Understanding Nuclear Stability: Magic Numbers in Physics

A pivotal set of numbers has served as the foundation of nuclear physics research for decades, revealing how they stem from the quantum interplay of nuclear particles and forces.
Nearly 80 years ago, physicist Maria Goeppert Mayer discovered that atomic nuclei exhibit remarkable stability when they contain specific numbers of protons and neutrons, such as 50 or 82. Subsequent research has reinforced the existence of these “magic numbers,” which characterize the most stable and abundant elements in the universe.
Goeppert Mayer’s contemporaries introduced the concept that protons and neutrons occupy discrete energy levels or shells. While this shell model persists in explaining numerous nuclear physics experiments by treating each nucleus particle as independent, modern quantum theory contends that these particles engage in strong interactions.
Yao Jianming and researchers from Sun Yat-sen University in China have reconciled this discrepancy, revealing how magic numbers originate from these interactions.
According to Yao, the shell model does not derive intricate details of particle interactions. Instead, he and his team approached their calculations from first principles, elucidating how particles interact, cling together, and the energy required to separate them.
Yao likens the two models to images captured at differing resolutions: “Historically, researchers either modeled the system at low resolution or explored nuclear structure at high resolution. We applied contemporary methods to bridge these models.”
The team initiated their analysis with a high-resolution perspective, then deliberately blurred it at each calculation stage, observing how particle structures evolved.
The researchers noted that the symmetry of a particle’s quantum state shifts across a mathematical bridge. By graphing these state equations, they produced shapes showcasing various symmetries at different resolutions. This transformation led to a nuclear structure where nuclei are most stable when particles correspond to magic numbers.
Jean-Paul Ebelin from the French Alternative Energy and Atomic Energy Commission emphasizes that this study offers a theoretical exploration akin to a mathematical microscope, effectively mirroring experimental observations. “Nature reveals a different facet depending on the observational resolution,” Ebelin notes.
The identified symmetry alterations correlate with effects noted in Albert Einstein’s special theory of relativity, as Ebelin points out, enhancing our understanding of how magic numbers unify various elements of nuclear theory.
To date, researchers have validated their theoretical findings on a specific type of tin, known for its double magic property due to possessing 50 protons and 82 neutrons, along with several other nuclei. Looking ahead, Yao expresses intentions to extend their analysis to heavier and typically unstable nuclei, exploring how these are formed during supernova events and the collision of neutron stars.
Have you skipped eating grapefruit due to its bitterness? The new CRISPR gene-edited variety may change your mind. Researchers have discovered that by disabling a specific gene, they can greatly diminish the bitter compounds found in grapefruit.
“The market for grapefruit could significantly expand,” states Nil Karmi from the Volcano Center in Rishon Lezion, Israel. “Many children avoid grapefruit due to its bitter taste.”
Karmi posits that this innovative approach could also aid the citrus industry amidst the threat of a devastating bacterial disease known as citrus greening.Huanglongbing poses significant risks to citrus, but cold-resistant varieties might mitigate these problems. “The insects responsible for spreading the disease cannot survive in regions with cold winters; however, the citrus varieties that can tolerate the cold are often too bitter for consumption,” he explains.
Gene-editing technology opens doors to creating cold-tolerant edible citrus varieties, allowing for cultivation in regions with temperate climates, such as Northern Europe, instead of only subtropical areas like Florida.
Citrus fruits have their distinctive sourness, particularly evident in lemons, but their bitterness stems from various compounds. Previous studies indicate that grapefruit’s bitterness is primarily linked to a compound called naringin, alongside related molecules like neohesperidin and poncitin.
To address this, Karmi’s team utilized CRISPR gene editing on a grapefruit variety to deactivate the genes responsible for producing these three bitter compounds. While grapefruit trees take several years to bear fruit, preliminary tests on the leaves show no presence of naringin, indicating that the fruit will likely be less bitter.
The modified trees also carry “marker genes” that facilitate easy identification of successfully edited plants. However, these marker genes complicate and increase the cost of obtaining permission to sell the fruit in various countries. In places like the United States and Japan, simple gene edits are not classified as genetic modifications, easing the approval process.
The team plans to replicate these gene edits in grapefruit without incorporating marker genes. “It’s a feasible plan, but it requires extensive effort,” adds Elena Plesser, also from the Volcano Center. “The process is quite challenging.”
While research teams globally are exploring similar gene-editing strategies, Karmi believes his group’s advancements are noteworthy.
The researchers are also targeting the same enzymes in cold-tolerant citrus varieties, such as pomelo, whose fruits are currently inedible due to elevated bitterness levels. The goal is to cross-breed these with popular citrus varieties like oranges to maintain cold hardiness while generating delicious, seedless fruit—a process expected to take years.
This gene editing may revolutionize the taste profile of numerous citrus fruits, claims Erin Mulvihill, who has studied naringin at the University of Ottawa, Canada.
Moreover, grapefruit consumption can pose challenges for some medications, particularly statins, as it inhibits liver enzymes responsible for processing these drugs, risking dangerously high drug levels for users. Naringin is a major player in these interactions, but, according to Muribihir, it’s not the sole factor. “To eliminate all grapefruit-drug interactions, multiple gene deletions would be necessary,” he states.

Earlier this month, NASA’s TESS space telescope successfully captured the faint glow and tail of an interstellar comet, further enriching its archive with observations that may provide critical insights into this unique celestial visitor from beyond our solar system.
This 3I/ATLAS image was captured by NASA’s TESS satellite on January 15, 2026. Image credit: NASA/Daniel Muthukrishna, MIT.
The interstellar comet 3I/ATLAS was discovered on July 1, 2025, by the NASA-funded ATLAS survey telescope in Rio Hurtado, Chile.
Known as C/2025 N1 (ATLAS) and A11pl3Z, this comet originated from the Sagittarius constellation.
3I/ATLAS holds the record for the most dynamically extreme orbit of any object tracked in our solar system.
It reached its closest approach to the Sun, or perihelion, on October 30, 2025.
The comet passed within 1.4 astronomical units (approximately 210 million km) of our Sun, just crossing Mars’ orbit.
After its brief obscuration behind the Sun, it reemerged near the triple star system Zania, located in the Virgo constellation.
According to MIT astronomer Daniel Muthukrishna and his team, “The TESS spacecraft systematically scans vast areas of the sky for about a month, looking for variations in light from distant stars to identify orbiting exoplanets and new worlds beyond our solar system.”
“Additionally, this technology enables TESS to detect and monitor remote comets and asteroids,” they added.
Notably, 3I/ATLAS had been observed prior to its official discovery in May 2025. For more details, you can read the findings.
From January 15 to 22, 2026, TESS re-observed the interstellar comet during a dedicated observation period.
The comet’s brightness measured approximately 11.5 times the apparent magnitude, making it about 100 times dimmer than what the human eye can perceive.
By revisiting the TESS data, astronomers successfully identified this faint comet by stacking multiple observations to track its motion, showcasing the extraordinary capabilities of the TESS mission.
IBM Quantum System Two: The Machine Behind the New Time Crystal Discovery

Recent advancements in quantum computing have led to the creation of a highly complex time crystal, marking a significant breakthrough in the field. This innovative discovery demonstrates that quantum computers excel in facilitating scientific exploration and novel discoveries.
Unlike conventional crystals, which feature atoms arranged in repeating spatial patterns, time crystals possess configurations that repeat over time. These unique structures maintain their cyclic behavior indefinitely, barring any environmental influences.
Initially perceived as a challenge to established physics, time crystals have been successfully synthesized in laboratory settings over the past decade. Recently, Nicholas Lorente and his team from the Donostia International Physics Center in Spain utilized an IBM superconducting quantum computer to fabricate a time crystal exhibiting unprecedented complexity.
While previous work predominantly focused on one-dimensional time crystals, this research aimed to develop a two-dimensional variant. The team employed 144 superconducting qubits configured in an interlocking, honeycomb-like arrangement, enabling precise control over qubit interactions.
By manipulating these interactions over time, the researchers not only created complex time crystals but also programmed the interactions to exhibit advanced intensity patterns, surpassing the complexity of prior quantum computing experiments.
This new level of complexity allowed the researchers to map the entire qubit system, resulting in the creation of its “state diagram,” analogous to a phase diagram for water that indicates whether it exists as a liquid, solid, or gas at varying temperatures and pressures.
According to Jamie Garcia from IBM, which did not participate in the study, this experiment could pave the way for future quantum computers capable of designing new materials based on a holistic understanding of quantum system properties, including extraordinary phenomena like time crystals.
The model emulated in this research represents such complexity that traditional computers can only simulate it with approximations. Since all current quantum computers are vulnerable to errors, researchers will need to alternate between classical estimation methods and precise quantum techniques to enhance their understanding of complex quantum models. Garcia emphasizes that “large-scale quantum simulations, involving more than 100 qubits, will be crucial for future inquiries, given the practical challenges of simulating two-dimensional systems.”
Biao Huang from the University of the Chinese Academy of Sciences notes that this research signifies an exciting advancement across multiple quantum materials fields, potentially connecting time crystals, which can be simulated with quantum computers, with other states achievable through certain quantum sensors.
Treponema pallidum Bacteria Linked to Syphilis and Related Diseases

New research reveals that traces of Treponema pallidum—the bacteria responsible for syphilis—have been identified in the bones of ancient inhabitants of Colombia, dating back over 5,000 years. This discovery suggests that syphilis was infecting humans far earlier than previously believed, prior to the advent of intensive agriculture, which many experts think may have facilitated its spread.
Currently, Treponema pallidum encompasses three subspecies that cause syphilis, bejel, and framboise. The origins and transmission pathways of these diseases remain topics of scientific debate. Although ancient DNA and infectious markers on bones offer insights, they are often limited and ambiguous.
In a groundbreaking study, researchers analyzed DNA from 5,500-year-old remains discovered in the Bogotá savannah. The unexpected finding of Treponema pallidum in a human leg bone provides critical evidence of its historical prevalence.
“This discovery was entirely unanticipated, as there was a lack of skeletal evidence indicating an infectious disease,” notes Nasreen Broumandkoshbacht from the University of California, Santa Cruz.
Many scholars have long posited that the majority of diseases affected humans only after the rise of intensive agriculture, which led to denser populations. However, this individual lived in a contrasting setting—small, nomadic hunter-gatherer bands that maintained close contact with wild animals.
“These results shed light on the extensive evolutionary history of these organisms,” states Davide Bozzi from the University of Lausanne, Switzerland. “They reveal longstanding relationships between the bacterium and human populations.”
As researchers, including Blumandhoschbacht and Bozzi, correlated ancient genomes with contemporary ones, they identified that the pallidum strain was part of a distinct lineage, separate from any known modern relatives. This indicates that early variants of syphilis were already diversifying and infecting humans in the Americas millennia ago, with many of the same genetic traits that make present-day strains particularly pathogenic.
The findings imply that these pathogens were not only early residents in the Americas but may have been affecting human populations globally for much longer than previously assumed.
Rodrigo Barquera, a researcher at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, suggests that this ancient strain might link to an elusive “missing” pathogen, Treponema carathaeum, known primarily for its physical characteristics rather than its genetic makeup.
Kertu Majumdar, a researcher at the University of Zurich in Switzerland, posits, “The genomes of even older organisms might provide insights into a variety of extinct lineages and diseases caused by these pathogens.”
For Bozzi, unearthing the evolutionary adaptations of pathogens like syphilis is crucial for understanding their genetic attributes that enhance their virulence in new hosts.
Geophysicists from Washington State University and Virginia Tech have uncovered a potential pathway for nutrient transport from the radioactive surface of Jupiter’s icy moon, Europa, to its subsurface ocean.
Artist’s concept of the oceans of Jupiter’s moon Europa. Image credit: NASA/JPL-Caltech.
Europa is believed to host more liquid water than all of Earth’s oceans combined, but this vast ocean lies beneath a thick, ice-covered shell that obstructs sunlight.
This ice layer means that any potential life in Europa’s oceans must seek alternative sources of nutrition and energy, raising important questions about how these aquatic environments can support life.
Moreover, Europa is under constant bombardment from intense radiation emitted by Jupiter.
This radiation interacts with salts and other surface materials on Europa, producing nutrients beneficial for marine microorganisms.
While several theories exist, planetary scientists have struggled to determine how nutrient-rich surface ice can penetrate the thick ice shell to reach the ocean below.
Europa’s icy surface is geologically active due to the gravitational forces from Jupiter; however, ice movements primarily occur horizontally rather than vertically, which limits surface-to-ocean exchange.
Dr. Austin Green from Virginia Tech and Dr. Katherine Cooper from Washington State University sought inspiration from Earth to address the surface recycling challenge.
“This innovative concept in planetary science borrows from well-established principles in Earth science,” stated Dr. Green.
“Notably, this approach tackles one of Europa’s persistent habitability questions and offers hope for the existence of extraterrestrial life within its oceans.”
The researchers focused on the phenomenon of crustal delamination, where tectonic compression and chemical densification in Earth’s crust lead to the separation and sinking of crustal layers into the mantle.
They speculated whether this process could be relevant to Europa, especially since certain regions of its ice surface contain dense salt deposits.
Previous investigations indicate that impurities can weaken ice’s crystalline structure, making it less stable than pure ice.
However, delamination requires that the ice surface be compromised, enabling it to detach and submerge within the ice shell.
The researchers proposed that dense, salty ice, surrounded by purer ice, could sink within the ice shell, thereby facilitating the recycling of Europa’s surface and nourishing the ocean beneath.
Using computer simulations, they discovered that as long as the surface ice is somewhat weakened, nutrient-rich ice laden with salts can descend to the bottom of the ice shell.
This recycling process is swift and could serve as a reliable mechanism for providing essential nutrients to Europa’s oceans.
The team’s study has been published in the Planetary Science Journal.

Alzheimer’s disease presents significant challenges, transforming a cherished family member into someone who often fails to recognize their true self. Many individuals ponder the reasons behind the erosion of memories and personalities. Researchers have identified the primary driver of Alzheimer’s as the accumulation of a brain protein known as Tau.
Under normal circumstances, tau protein plays a crucial role in preserving the health of nerve cells by stabilizing the microtubules, which function as pathways for nutrient transport. However, in Alzheimer’s patients, tau protein becomes twisted and tangled, obstructing communication between cells. These tau tangles are now recognized by medical professionals as a defining characteristic of Alzheimer’s disease, serving as indicators of cognitive decline.
Recent studies have shown that tau tangles correlate with diminished brain function in individuals affected by Alzheimer’s disease. Additionally, the apolipoprotein E4 (APOE4) gene is closely linked to late-onset Alzheimer’s and may exacerbate tau tangling. This gene encodes a protein involved in transporting fats and cholesterol to nerve cells throughout the brain.
A team from the University of California, San Francisco, and the Gladstone Institute has discovered that eliminating APOE4 from nerve cells can mitigate cognitive issues associated with Alzheimer’s. Their research involved specially bred mice exhibiting tau tangles and various forms of the human APOE gene, specifically APOE4 and APOE3. The aim was to determine if APOE4 directly contributes to Alzheimer’s-related brain damage and if its removal could halt cognitive decline.
To investigate the impact of the APOE4 gene, the researchers introduced a virus containing abnormal tau protein into one side of each mouse’s hippocampus. When the mice reached 10 months of age, the team conducted various tests—including MRI scans, staining of brain regions, microscopy, brain activity assessments, and RNA sequencing—to analyze the accumulation of tau protein in the brains of those with and without the APOE4 gene.
The findings revealed significant discrepancies between the two groups. Mice with the APOE4 gene displayed a higher prevalence of tau tangles, a marked decline in brain function, and increased neuronal death, while those with the APOE3 gene exhibited minimal tau deposits and no cognitive decline.
Next, the researchers employed a protein linked to an enzyme called CRE to excise the APOE4 gene from mouse nerve cells, subsequently measuring tau levels with a specialized dye. The results indicated a significant reduction in tau tangles, dropping from nearly 50% to around 10%. In contrast, mice carrying the APOE3 gene saw an even smaller reduction from just under 10% to approximately 3%.
Additionally, a different dye was utilized to quantify amyloid plaques—another protein cluster frequently found in Alzheimer’s cases. The outcomes showed that, following removal of the APOE4 gene, amyloid plaque levels decreased from roughly 20% to less than 10%. Mice with the APOE3 gene, however, displayed no notable change, consistently maintaining around 10% amyloid plaques.
The researchers further analyzed the RNA of the mice to understand how APOE4 affects neurons and other brain cells. Their observations confirmed that the presence of APOE4 correlated with an uptick in Alzheimer’s-related brain cells. This finding helped illustrate that eliminating APOE4 from nerve cells resulted in diminished responses associated with Alzheimer’s disease.
In conclusion, the researchers determined that APOE4 is detrimental and may actively induce Alzheimer’s-like damage in the brains of mice. While further validation in human subjects is needed, the implications of this gene may pave the way for developing targeted therapies for Alzheimer’s disease.
Researchers from the University of Waterloo and Kyushu University have achieved a groundbreaking advancement in quantum computing by developing a novel method to create redundant, encrypted copies of qubits. This represents a pivotal step towards practical quantum cloud services and robust quantum infrastructure.

In quantum mechanics, the no-cloning theorem asserts that creating an identical copy of an unknown quantum state is impossible.
Dr. Achim Kempf from the University of Waterloo and Dr. Koji Yamaguchi from Kyushu University emphasize that this fundamental rule remains intact.
However, they have demonstrated a method to generate multiple encrypted versions of a single qubit.
“This significant breakthrough facilitates quantum cloud storage solutions, such as quantum Dropbox, quantum Google Drive, and quantum STACKIT, enabling the secure storage of identical quantum information across multiple servers as redundant encrypted backups,” said Dr. Kemp.
“This development is a crucial step towards establishing a comprehensive quantum computing infrastructure.”
“Quantum computing offers immense potential, particularly for addressing complex problems, but it also introduces unique challenges.”
“One major difficulty in quantum computing is the no-duplication theorem, which dictates that quantum information cannot be directly copied.”
“This limitation arises from the delicate nature of quantum information storage.”
According to the researchers, quantum information functions analogously to splitting passwords.
“If you possess half of a password while your partner holds the other half, neither can be utilized independently. However, when both sections are combined, a valuable password emerges,” Dr. Kemp remarked.
“In a similar manner, qubits are unique in that they can share information in exponentially growing ways as they interconnect.”
“A single qubit’s information is minimal; however, linking multiple qubits allows them to collectively store substantial amounts of information that only materializes when interconnected.”
“This exceptional capability of sharing information across numerous qubits is known as quantum entanglement.”
“With 100 qubits, information can be simultaneously shared in 2^100 different ways, allowing for a level of shared entangled information far exceeding that of current classical computers.”
“Despite the vast potential of quantum computing, the no-cloning theorem restricts its applications.”
“Unlike classical computing, where duplicating information for sharing and backup is a common practice, quantum computing lacks a simple ‘copy and paste’ mechanism.”
“We have uncovered a workaround for the non-replicability theorem of quantum information,” explained Dr. Yamaguchi.
“Our findings reveal that by encrypting quantum information during duplication, we can create as many copies as desired.”
“This method circumvents the no-clonability theorem because when an encrypted copy is selected and decrypted, the decryption key is automatically rendered unusable; it functions as a one-time key.”
“Nevertheless, even one-time keys facilitate crucial applications such as redundant and encrypted quantum cloud services.”
Deep within Bolivia’s seasonally flooded savannah, a small olive-green songbird has eluded scientific classification for decades. After 60 years of misidentification, ornithologists have finally confirmed that this bird is not merely a regional variant within the genus Hylophilus. It represents a completely new species. This discovery adds to South America’s rich avian diversity and underscores the vast unknowns still present within even well-studied bird families.
Beni Greenlet (Hylophilus moxensis), January 10, 2024, in its habitat near San Ramon, Beni, Bolivia. Observe the pale brownish-gray pinnae, dark lore, the base of the dark commissures, the clefts across the crown and frontal area, and the dark iris. Image credit: Tini Wijpkema.
The newly identified species belongs to the Hylophilus genus, part of the Vireonidae family, which includes vireos, greenlets, and shrikes.
With the scientific name Hylophilus moxensis (common name: Beni Greenlet), this bird thrives in the wet scrublands of Bolivia’s Beni Savannah, an ecologically unique area also known as Llanos de Moxos.
“Morphological differences among many Hylophilus Greenlet species are subtle. Most display shades of green, gray, yellow, and brown,” explains Dr. Paul Van Els, an ornithologist at the National Museum of History in La Paz, Bolivia. He and his colleagues detailed their findings in a recent paper.
“For certain species, iris color is one of the most effective traits to differentiate them from similarly appearing relatives.”
By analyzing one mitochondrial and three nuclear genes, the research team clarified the uncertainty surrounding this population.
Results revealed that the Beni population is distinct from known species and is more closely related to Hylophilus poirotis and Hylophilus amaurocephalus, which diverged approximately 6.6 million years ago.
In contrast, the latter two species separated from one another about 3.5 million years ago.
Van Els and his team also conducted comprehensive analyses of facial plumage, eye color, and vocalizations.
Research indicates that the Hylophilus moxensis can be uniquely identified by the absence of black or brown markings behind the ears, a trait consistently found in closely related species, along with uniformly dark brown eyes and a distinctive vocal pattern.
In vocal studies, researchers observed that this species’ calls feature “V-shaped notes,” and their vocalizations include overtones reminiscent of female Hylophilus amaurocephalus calls—a unique combination not shared with either comparative species.
The discovery of Hylophilus moxensis contributes to a growing list of endemic species found in the Beni savannah.
While scientists currently do not regard this species as threatened with extinction, they caution that extensive agricultural burning poses significant threats to the region’s biodiversity.
“Recognizing Hylophilus moxensis should enhance conservation priorities in this area,” the authors noted.
“Rampant agricultural burning poses a serious risk to the region’s biodiversity.”
“Though we cannot accurately estimate the population size of Hylophilus moxensis, we do not currently consider it at risk of extinction, as there remains extensive suitable habitat.”
“However, the relatively low number of sightings might indicate issues beyond mere observer rarity, potentially reflecting a truly localized population.”
Many individuals set New Year’s resolutions to lose weight, particularly following the holiday festivities. Traditionally, this involved adopting a new diet, waking up early for workouts, and other habits that can be challenging to sustain. Consequently, it’s no surprise that numerous people abandon their goals within weeks.
Today, however, an alternative has emerged: weight loss medications. Instead of solely depending on lifestyle changes, individuals can benefit from regular doses of GLP-1 agonists or other therapeutic tablets (as highlighted on page 6). Health professionals still recommend integrating these medications with consistent physical activity for optimal results.
GLP-1 drugs are not only transforming our cyclical health regimens. Restaurants are now crafting menus specifically for Ozempic diners, featuring smaller portion sizes for customers who experience reduced appetite. Additionally, supermarkets have reported declines in sales due to decreased demand from those using these medications. Airlines are also considering the implications, as decreased average passenger weight could lower fuel expenses.
While it’s unclear how much these trends can be attributed to GLP-1 drugs—which are currently used by a minority—and the extent of their impact on brands reacting to this health trend, the statistics surrounding obesity are alarming. Approximately 1 billion individuals globally are affected by obesity, and the adoption of these medications is expected to rise. According to World Health Organization estimates, fewer than 10 percent of people will utilize GLP-1 drugs by 2030, yet this still represents a substantial demographic.
“
Restaurants are designing menus featuring reduced portions for Ozempic diners. “
New advancements in medication are in development (refer to page 7), and the potential impacts could be even more significant. Beyond weight reduction, GLP-1 agonists have shown promise in treating various conditions, from addiction to eye diseases like cataracts.
While there remain numerous uncertainties regarding the long-term consequences, the results of discontinuation, and enhancing accessibility, the future appears bright. As we advance further into the 21st century, weight loss drugs are poised to play a crucial role in shaping health and wellness trends.
Quantum Computers: Solutions for Chemistry Challenges
Marijan Murat/DPA/Alamy
One of the critical questions in the quantum computing sector is whether these advanced machines can solve practical problems in fields like chemistry. Researchers in industrial and medical chemistry are poised to provide insights by 2026.
The complexity of determining the structure, reactivity, and other properties of molecules is inherently a quantum problem, primarily involving electrons. As molecular structures grow increasingly complex, these calculations become challenging, sometimes even surpassing the capabilities of traditional supercomputers.
Quantum computers, being inherently quantum, have a potential advantage in tackling these complex chemical calculations. As these computers develop and become more seamlessly integrated with conventional systems, they are gaining traction in the chemistry sector.
For instance, in 2025, IBM and the Japanese Institute of Scientific Research collaborated, employing quantum computers alongside supercomputers to model various molecules. Google researchers have also been innovating algorithms that unveil molecular structures. Additionally, RIKEN researchers are teaming up with Quantinuum to create efficient workflows, allowing quantum computers to calculate molecular energy with remarkable precision. Notably, the quantum computing software platform Kunova Computing introduced an algorithm that reportedly operates ten times more efficiently than traditional methods for energy calculations.
Progress is expected to expedite by 2026 as quantum computers become more advanced. “Future larger machines will allow us to create enhanced workflows, ultimately solving prevalent quantum chemistry problems,” states David Muñoz Ramo from Quantinuum. While his team currently focuses on hydrogen molecules, they foresee stepping into more intricate structures, such as catalysts for industrial reactions.
Other research entities are making strides in similar areas. In December, Microsoft announced a partnership with Algorithmiq, a quantum software startup, aimed at accelerating the development of quantum algorithms for chemistry. Furthermore, a study by Hyperion Research highlights chemistry as a focal area for advancement and investment in quantum computing, ranking it as one of the most promising applications in annual surveys.
However, meaningful progress in quantum chemical calculations depends on achieving error-free or fault-tolerant quantum computers, which will also unlock other potential applications for these devices. As Philip Schleich and Alan Aspuru-Guzik emphasized in a commentary for Science magazine, the ability of quantum computers to outperform classical computers hinges on the development of fault-tolerant algorithms. Thankfully, achieving fault tolerance is a widely accepted goal among quantum computer manufacturers worldwide.
Alzheimer’s Disease (AD) has long been deemed irreversible. However, a groundbreaking study by scientists from Case Western Reserve University, University Hospitals, and the Louis Stokes Cleveland VA Medical Center reveals that treatment for advanced Alzheimer’s disease can be reversed. Through extensive research on both preclinical mouse models and human brain samples, the team discovered that the brain’s failure to maintain normal levels of nicotinamide adenine dinucleotide (NAD+), the crucial energy molecule of cells, significantly contributes to the onset of Alzheimer’s. Furthermore, sustaining an appropriate NAD+ balance may not only prevent but also reverse the progression of Alzheimer’s disease.
Alzheimer’s disease severity correlates with NAD+ homeostatic dysregulation. Image credit: Chaubey et al., doi: 10.1016/j.xcrm.2025.102535.
Historically, Alzheimer’s disease, the primary cause of dementia, has been regarded as irreversible since its identification over a century ago, and it is expected to impact more than 150 million individuals globally by 2050.
Current therapies focused on amyloid beta (Aβ) and clinical symptoms offer limited benefits, underscoring the urgent need for complimentary and alternative treatment options.
Intriguingly, individuals with autosomal dominant AD mutations can remain symptom-free for decades, while others without Alzheimer’s neuropathology maintain cognitive function despite having numerous amyloid plaques.
These insights indicate potential intrinsic brain resilience mechanisms that may slow or halt disease progression, suggesting that enhancing these processes could enhance recovery from Alzheimer’s disease.
NAD+ homeostasis plays a pivotal role in cellular resilience against oxidative stress, DNA damage, neuroinflammation, blood-brain barrier degradation, impaired hippocampal neurogenesis, deficits in synaptic plasticity, and overall neurodegeneration.
In a recent study, Professor Andrew Pieper and his team from Case Western Reserve University discovered that NAD+ levels decrease significantly in the brains of Alzheimer’s patients, a trend also observed in mouse models.
While Alzheimer’s disease is unique to humans, it can be effectively modeled using genetically engineered mice that carry mutations linked to human Alzheimer’s disease.
The researchers utilized two distinct mouse models: one with multiple human mutations affecting amyloid processing and another with a human mutation in the tau protein.
Both models exhibited Alzheimer’s-like brain pathology, including blood-brain barrier degradation, axonal degeneration, neuroinflammation, impaired hippocampal neurogenesis, diminished synaptic transmission, and excessive oxidative damage.
They also developed cognitive impairments typical of Alzheimer’s patients.
Upon discovering the sharp decline in NAD+ levels in both humans and mice with Alzheimer’s, the scientists investigated whether preserving NAD+ levels before disease onset and restoring them after significant disease progression could prevent or reverse Alzheimer’s.
This research builds upon prior work showing potential recovery by restoring NAD+ balance following severe brain injuries.
The team achieved NAD+ balance restoration using a well-known pharmacological agent, P7C3-A20.
Remarkably, maintaining NAD+ balance not only shielded mice from developing Alzheimer’s but also enabled brain recovery from key pathological changes even when treatment was delayed in advanced disease stages.
Subsequently, both mouse strains fully regained cognitive function, accompanied by normalized levels of phosphorylated tau-217—a recently recognized clinical biomarker for Alzheimer’s disease in humans—confirming the restoration of cognitive function and highlighting a potential biomarker for future Alzheimer’s disease reversal trials.
“We are excited and hopeful about these results,” said Professor Pieper.
“Restoring brain energy balance led to both pathological and functional recovery in mice with advanced Alzheimer’s disease.”
“Observing this effect across two different animal models, driven by distinct genetic causes, reinforces the notion that recovery from progressive Alzheimer’s disease may be achievable through the restoration of brain NAD+ balance.”
These findings encourage a shift in how researchers, clinicians, and patients perceive treatment options for Alzheimer’s disease moving forward.
“The key takeaway is one of hope. Alzheimer’s disease effects may not necessarily be permanent,” noted Professor Pieper.
“Under certain conditions, the damaged brain can self-repair and regain functionality.”
“Through our research, we not only demonstrated a drug-based method for promoting recovery in animal models but also identified candidate proteins in human AD brains that may aid in reversing the disease,” remarked Dr. Kalyani Chaubey, a researcher at Case Western Reserve University and University Hospitals.
While current commercially available NAD+ precursors have been shown to elevate cellular NAD+ to unsafe levels—potentially promoting cancer—the pharmacological approach of this study employs P7C3-A20, which allows cells to maintain optimal NAD+ levels under stress without elevating them excessively.
“This is a crucial consideration for patient care, and clinicians should explore therapeutic strategies aimed at restoring the brain’s energy balance as a viable path toward disease recovery,” Professor Pieper concluded.
For more detailed information, see the study findings published in Cell Reports Medicine.

A rare triple-merger galaxy, known as J121/1219+1035, hosts three actively feeding radio-bright supermassive black holes, as revealed by a team of American astronomers.
Artist’s impression of J121/1219+1035, a rare trio of merging galaxies, featuring three radioactively bright supermassive black holes actively feeding, with jets illuminating the surrounding gas. Image credit: NSF/AUI/NRAO/P. Vosteen.
The J1218/1219+1035 system is located approximately 1.2 billion light-years from Earth.
This unique galaxy system contains three interacting galaxies, each harboring supermassive black holes at their centers that are actively accreting material and shining brightly in radio frequencies.
Dr. Emma Schwartzman, a research scientist at the US Naval Research Laboratory, states: “Triple active galaxies like J1218/1219+1035 are incredibly rare, and observing them during a merger allows us a front-row seat to the growth of supermassive galaxies and their black holes.”
“Our observations confirmed that all three black holes in J1218/1219+1035 are emitting bright radiation and actively firing jets. This supports the theory of active galactic nuclei (AGN) and provides insight into the life cycle of supermassive black holes.”
Schwartzman and colleagues utilized NSF’s Very Large Array (VLA) and Very Long Baseline Array (VLBA) to study J1218/1219+1035.
The findings confirmed that each galaxy hosts a compact synchrotron-emitting radio core, indicating that all three harbor AGNs powered by growing black holes.
This discovery makes J1218/1219+1035 the first confirmed triple radio AGN and only the third known triple AGN system in nearby space.
“The three galaxies within J1218/1219+1035, located about 22,000 to 97,000 light-years apart, are in the process of merging, resulting in a dynamically connected group with tidal signatures indicative of their interactions,” the astronomers noted.
“Such triple systems are crucial in the context of hierarchical galactic evolution, wherein large galaxies like the Milky Way grow through successive collisions and mergers with smaller galaxies, yet they are seldom observed.”
“By capturing three actively feeding black holes within the same merging group, our new observations create an excellent laboratory for testing how galactic encounters funnel gas into centers and stimulate black hole growth.”
J1218/1219+1035 was initially flagged as an anomalous system through mid-infrared data from NASA’s Wide-Field Infrared Surveyor (WISE), which suggested the presence of at least two obscured AGNs within the interacting galaxies.
Optical spectroscopy confirmed one AGN in a core while revealing complex signatures in another, although the nature of the third galaxy remained uncertain due to the possibility of emissions from star formation.
“Only through new ultra-sharp radio imaging with VLA at frequencies of 3, 10, and 15 GHz did we uncover compact radio cores aligned with all three optical galaxies, confirming that each hosts an AGN bright in radio emissions and likely fueling small-scale jets and outflows,” the researchers explained.
“The radio spectra of the three cores exhibited traits consistent with non-thermal synchrotron radiation from the AGNs, featuring two sources with typical steep spectra and a third with an even steeper spectrum potentially indicative of unresolved jet activity.”
In 1900, mathematician David Hilbert presented a list of mathematical problems that captured both the current state and future trajectory of mathematics. Now, 125 years later, Dr. Zahel Hani and his colleagues at the University of Michigan have successfully solved one of Hilbert’s enduring puzzles, significantly unifying various physical laws in the process.
Hilbert advocated for deriving all physical laws from mathematical axioms—assertions regarded as fundamental truths by mathematicians. His sixth problem sought to derive laws governing fluid behavior from such axioms.
Until 2025, physicists characterized fluids through three distinct paradigms based on scale: the microscopic scale of individual particles, the mesoscopic world of particle clusters, and the macroscopic scope of full-fledged fluids, such as water flowing in pipes. Despite advances in linking these scales, a seamless unification remained elusive until Hani and his team devised a solution.
The researchers’ breakthrough hinged on adapting diagram-based techniques pioneered by physicist Richard Feynman for the seemingly unrelated field of quantum field theory. This endeavor culminated in a published paper reflecting a five-year research initiative.
“We received validation of our results from numerous experts in the field,” Hani asserts. The study, currently available as a preprint, will soon appear in a highly regarded mathematics journal.
The findings represent not only a monumental achievement in mathematics but also offer the potential to enhance our understanding of complex fluid dynamics in natural systems, such as the Earth’s atmosphere and oceans. Hani notes they are also exploring a quantum variant of this issue, where microscale mathematics can reveal even more complex and intriguing particle behaviors.
Dark Photons: A New Explanation for the Double-Slit Experiment
Russell Kightley/Science Photo Library
This year, a fundamental aspect of quantum theory faced scrutiny when researchers introduced a groundbreaking interpretation of an experiment exploring the nature of light.
Central to this research was the historic double-slit experiment, first conducted by physicist Thomas Young in 1801, which confirmed the wave-like behavior of light. Conventionally, particles and waves are considered distinct; however, in the quantum realm, they coexist, showcasing wave-particle duality.
For years, light stood as the quintessential example of this duality. Experimentation demonstrated that light can exhibit particle-like behavior as photons and wave-like characteristics, culminating in interference patterns reminiscent of Young’s findings. However, earlier in 2023, Celso Villas Boas and his team at Brazil’s Federal University of São Carlos proposed a novel interpretation of the double-slit experiment, exclusively utilizing photons and negating the wave aspect of optical duality.
After New Scientist covered their study, the team received significant interest from peers, with citations soaring. Villas-Boas shared, “I’ve received numerous invitations to present, including events in Japan, Spain, and Brazil,” emphasizing the widespread intrigue.
In the traditional double-slit experiment, an opaque barrier containing two narrow slits is positioned between a screen and a light source. Light travels through the slits to create a pattern of alternating bright and dark vertical stripes, known as classical interference, usually attributed to colliding light waves.
The researchers shifted away from this conventional explanation, examining the so-called dark state of photons—a unique quantum state that prevents interaction with other particles, hence not illuminating the screen. This perspective eliminates the necessity for light waves to clarify the observed dark stripes.
This reevaluation challenges a deeply ingrained view of light within quantum physics. Many educators expressed concern, with some remarking, “Your findings challenge the foundational concepts I’ve taught for years.” However, while some colleagues embraced the new perspective, others remained skeptically intrigued, following New Scientist‘s initial report.
Villas-Boas has been actively exploring implications surrounding the dark state of photons. His investigations revealed that thermal radiation, such as sunlight, can reside in a dark state, concealing a substantial portion of its energy due to a lack of interaction with other objects. Experimental validation could involve placing atoms in cavities where their interactions with light are meticulously examined, according to Villas-Boas.
His team’s reinterpretation of interference phenomena facilitates comprehension of previously perplexing occurrences, such as non-overlapping wave interactions. Moving beyond the wave model to incorporate distinct bright and dark photon states opens avenues for innovative applications. Villas-Boas envisions potential developments such as light-controlled switches and devices that selectively permit specific light types to pass.
In his view, all these explorations connect back to the essential principles of quantum physics, highlighting that engaging with quantum objects necessitates understanding their interactions with measurement devices—encompassing darkness itself. “This concept is intrinsic to quantum mechanics,” Villas-Boas asserts.
Huntington’s Disease: A Gradual Destruction of Brain Cells.
Science Photo Library/Alamy
This year marks a watershed moment in addressing Huntington’s disease, a rare yet impactful form of dementia. Researchers have achieved a groundbreaking milestone with an experimental gene therapy that effectively slows the advancement of this debilitating condition for the first time ever. This represents a significant breakthrough in the search for viable treatments.
According to Sarah Tabrizi from University College London, “This is a monumental step forward,” referencing the successes observed in late-stage trials earlier this year. “We now understand that Huntington’s disease is potentially treatable, presenting us with a tremendous opportunity.”
Huntington’s disease stems from a genetic mutation that causes the normally benign huntingtin protein to cluster into harmful aggregates within the brain. This accumulation leads to gradual deterioration of brain cells, hindering movement, cognitive function, and emotional well-being. Currently, no approved treatments halt the progression of symptoms, and care primarily focuses on supporting affected individuals.
The novel treatment, dubbed AMT-130, directly targets these abnormal proteins by delivering genetic instructions to brain cells, instructing them to produce molecules that inhibit protein formation.
In a recent investigation, Tabrizi and her team administered high doses of AMT-130 to 17 patients with Huntington’s disease. They evaluated changes in cognitive, motor, and daily functioning over a three-year period compared to a control group. Preliminary results released by the drug’s manufacturer, biotechnology firm uniQure, indicate a remarkable 75% average slowdown in symptom progression.
“Huntington’s disease treatment has faced numerous challenges in recent years,” stated Sarah O’Shea at Mount Sinai in New York, who was not involved in the study. “This accomplishment is significant, not just in delaying the disease’s progression but also because it arrives at a crucial time when hope is desperately needed.”
Nevertheless, this innovative treatment does come with its own set of challenges. Tabrizi explained that the 12- to 18-hour surgical procedure required to deliver the treatment deep within the brain is only accessible in a limited number of facilities in select countries, including the U.S. and U.K. Additionally, if approved, the treatment is likely to be prohibitively expensive. “Will it be accessible to all? Achieving that will be a challenge,” she remarked.
To navigate these hurdles, Tabrizi and her team are developing an alternative therapy that involves injecting the fluid around the spinal cord. “We’re currently conducting a Phase I study, and the first patient was treated in November 2024,” Tabrizi noted, with safety results expected by July 2026.
Meanwhile, uniQure’s executives revealed in September plans to submit AMT-130 for FDA approval in early 2026. However, the submission timeline is now uncertain, as the FDA has expressed concerns regarding the study plan and the control group, which consists of *non-treatment* patients drawn from a database.
The absence of a proper control group complicates the ability to discern the placebo effect on results. Still, given the surgical nature of the treatment, establishing such a group poses significant challenges.
“We firmly believe that AMT-130 holds substantial potential to benefit patients and are dedicated to collaborating with the FDA to expedite access to this treatment for families in need across the U.S.,” stated Matt Kapusta, CEO of uniQure.
Ornithologists have utilized camera traps to document a newly identified species of jewel bubbler in the lush karst forests of Papua New Guinea’s Southern Fold Mountains.
Camera trap images showcasing the holotype and two paratypes of Ptilorrhoa urrissia taken during a detailed 3-month sampling in a high-density array over 0.5 ha. The holotype (ac, marked ‘h’ in image a) and a paratype (a and d, marked ‘p’ in image a), an adult female and juvenile with female-type plumage, were photographed together on January 1, 2020. The shown image is from a sequence of 20 photos captured within 87 seconds. A putative adult male paratype (e) was photographed on March 8, 2020, from under 40 meters. Image credit: Woxvold et al., doi: 10.1111/ibi.70016.
The newly identified species falls under the genus Ptilorrhoa, known for small birds in the family Cinclosomatidae.
Commonly referred to as jewel bubblers, these unique birds are endemic to New Guinea.
According to Ian Wachsvold, an ornithologist with the Australian Museum Research Institute, “Jewel bubblers are a group of ground-dwelling, insectivorous passerines found exclusively in New Guinea and nearby land-bridge islands.”
“These birds are characterized by their plump bodies, short wings, black masks, and white throat or cheek patches, with many species having soft feathers adorned with blue or maroon markings.”
“Typically vocal but shy, they dwell deep within the forests, making them more often heard than seen.”
“Currently, there are four recognized species, with three found across much of New Guinea, differentiated mainly by their altitude – Ptilorrhoa caerulescens lives in lowland areas, while Ptilorrhoa castanonota resides in hills and low mountains; Ptilorrhoa leucosticta prefers dense forests.”
“The fourth species, the brown-headed jewel bubbler (Ptilorrhoa geislerorum), has been recorded in two geographically separated regions: the hills and lowlands of northeastern Papua New Guinea, and a recently discovered population presumed to be this species located far west of Yapen Island.”
In 2017, Dr. Wachsvold and Leo Regula from Lihir Gold Ltd. initiated a biennial camera trap monitoring program for ground-dwelling birds and mammals on the Igif Ridge (Uri [mount] Uricia in the local Fasu language), a limestone forested anticline situated on the southeastern fringe of the Agogo Mountains in the Southern Highlands Province of Papua New Guinea.
Throughout this research, distinctive, undescribed jewel bubblers were captured on camera.
“During over 1,800 camera days, we recorded 10 images of the bird across three sequences (trigger events) using two cameras set approximately 600 meters apart,” the researchers noted.
“In November 2018, we attempted to set up mist nets to capture these birds but were unsuccessful.”
“Camera trap surveillance was repeated in 2019, 2021, and 2024, accumulating a total of 94 photographs (22 sequences) and seven 30-second videos (4 sequences) featuring at least three to six birds, with 11 cameras monitoring an area of 16 hectares.”
Analysis of museum specimens alongside field photographic evidence confirms that the bird in question distinctly differs from other known Ptilorrhoa species.
Pyroroa urrissia),” they stated.
Pyroroa urrissia appears to be a resident species in the Yagif Ridge area, with birds photographed consistently over a span of ten consecutive months (June through March) across seven years.
The total number of newly detected species during the sampling period probably comprises fewer than ten birds.
“This species tends to be observed alone, in pairs, or in small family groups of three to four,” the researchers highlighted.
“Data indicates a similar social organization to other jewel bubblers worldwide. The Pyroroa urrissia duo is frequently photographed together, with most records (all but 3 sequences of one male) gathered from a 7 ha area; most likely indicating two breeding events involving a resident pair and their offspring.”
“We hypothesize that the Igif Ridge supports a fragmented population occupying an isolated low mountain lacking higher altitude support for Ptilorrhoa leucosticta,” they add.
“Potentially suitable habitats may be restricted to regions between Mt Bosabi and Mt Karimui in southern Papua New Guinea.”
To date, no songs have been distinctly attributed to any Ptilorrhoa species aside from Ptilorrhoa castanonota, although the team did encounter vocalizations on the Igif Ridge.
The new species appears to produce softer calls compared to other species such as Ptilorrhoa caerulescens and Ptilorrhoa castanonota, while showing behavioral similarities to Ptilorrhoa leucosticta.
“Jewel bubblers on the Igif Ridge are threatened by multiple factors,” scientists warn.
“Known native predators include at least three marsupials, such as the New Guinea quoll (Dasyrus albopuntatus), the woolly three-striped dasher (Myoichthys leucula), and certain Murexia species. Furthermore, the Papuan eagle (Harpyopsis novaeguineae), goshawk (Accipiter poliocephalus), and the great owl (Tito tenebricosa) prey on the ground, possibly targeting adult birds or their young.”
“Invasive predators represent an additional significant risk, especially for ground-nesting species like the jewel bubbler.”
“Domestic cats (Felis catus) have been photographed on Igif Ridge thrice in 2021 and 2024.”
“Dogs (Canis lupus familiaris) are frequently spotted in the area, often accompanying hunters or loitering opportunistically.”
“Lastly, climate change poses a severe threat to tropical montane birds, particularly those like Pyroroa urrissia that have limited dispersal capabilities and no access to high-altitude environments on Igif Ridge.”
The findings of this significant discovery were published in a study in the journal Toki on November 26, 2025.

Worldwide, drug-resistant gonorrhea is increasing, yet new antibiotics may provide a temporary solution until we face bacterial strains that cannot be treated at all, which heightens the risk of infertility.
Every year, it is estimated that sexually transmitted infections affect over 80 million individuals globally. Gonorrhea infections can spread to various body parts, including the anus, urethra, and genitals. Symptoms often include a burning sensation during urination and unusual discharge from genital areas. Untreated infections can lead to complications such as infertility and miscarriage.
Typically, the treatment for gonorrhea involves ceftriaxone injections, which remain effective against most strains. However, resistance is developing, and the World Health Organization reported that in 2024, about 5 percent of cases in 12 countries, including Thailand, South Africa, and Brazil, showed resistance to ceftriaxone—a sixfold increase since 2022.
When ceftriaxone fails, doctors typically resort to alternative antibiotics. However, it’s only a matter of time before completely untreatable strains appear. “We’re running out of options,” states Alison Luckey from the Global Antibiotic Research and Development Partnership. “It’s been decades since a new treatment for gonorrhea has been approved.”
To combat this escalating issue, researchers found that gepotidacin, an antibiotic pill used for urinary tract infections, can effectively treat gonorrhea, and the U.S. Food and Drug Administration (FDA) is now reviewing the drug for U.S. approval. However, as bacteria evolve resistance to new medications, expanding treatment options is crucial, according to Lackey.
She and her team are currently studying another medication, zoliflodacin, specifically created to combat drug-resistant gonorrhea. In a study, 744 gonorrhea patients from the U.S., South Africa, Thailand, Belgium, and the Netherlands were randomly assigned to receive either zoliflodacin or a combination treatment that includes ceftriaxone and a second antibiotic, azithromycin.
After six days of testing through swabs of participants’ cervixes or urethras, results showed that zoliflodacin effectively cleared roughly 91 percent of infections, while standard treatment had a similar success rate of around 96 percent. Hence, no significant differences were observed between the two treatments, with side effects like headache and nausea being similar and short-lived in both groups.
Most of the 744 tested cases involved strains that were not resistant to ceftriaxone or azithromycin, but prior research indicated that zoliflodacin can effectively target N. gonorrhoeae strains resistant to all standard antibiotics. These findings suggest that zoliflodacin may represent a promising new strategy for treating gonorrhea, both as a first-choice treatment and when traditional options fail, as Lackey observes. “In areas with frequent resistance, early implementation as a primary treatment option could be beneficial,” she adds. Furthermore, since zoliflodacin is administered orally, it may provide a more convenient alternative than ceftriaxone, which some patients avoid due to needle aversion.
Researchers have already submitted findings to the FDA, with a ruling anticipated by December 15, according to Lackey.
If the FDA grants approval, other regions, including the UK, Europe, and Asia, could follow suit shortly, as noted by Charlotte Eve Short from Imperial College London, who was not part of the research.
Alongside ongoing vaccination efforts against gonorrhea, including the recent rollout of the Meningitis Group B vaccine in the UK, the introduction of these two new drugs could signify a pivotal moment in the battle against drug-resistant gonorrhea, according to Short. “This is excellent news,” she states. “While the population-level implications remain uncertain, our dual focus on prevention and treatment should help us significantly reduce resistance rates.”
Research conducted on Anopheles mosquitoes, native to Tanzania, shows promising results in malaria control.

A genetic technology known as gene drive has the potential to aid in malaria prevention by transferring genes to wild mosquitoes that inhibit parasite transmission. Recent tests in a Tanzanian lab have indicated that one specific gene drive could be effective if released within the country.
“This technology is poised to be transformative,” states George Christofides from Imperial College London.
Typically, a portion of an organism’s DNA is passed to only half of its offspring due to the halving of DNA in eggs or sperm. By enhancing this inheritance rate using gene drives, small segments of DNA can proliferate swiftly within a population, even if they do not confer any evolutionary advantages.
Many natural gene drives function through various means, potentially even in some human communities. In 2013, scientists engineered an artificial gene drive utilizing CRISPR gene-editing technology, allowing DNA segments to be copied from one chromosome to another.
The objective is to disseminate DNA segments that impede malaria transmission, but the question remains: which segments? Christofides revealed in 2022 that the development of malaria parasites in mosquitoes could be notably curtailed by two small proteins, one derived from honeybees and another from Xenopus. The genes linked to these anti-malarial proteins correspond with those that produce enzymes aiding in blood digestion, so the proteins are synthesized post-blood meal, secreted into the intestine.
However, these tests used lab strains of mosquitoes and malaria pathogens collected decades ago, leaving uncertainty regarding the effectiveness of this method in contemporary Africa.
Currently, Christofides and Dixon Rwetoihera from the Ifakara Health Research Institute in Tanzania have updated local data. The Anopheles gambiae mosquitoes, derived from this strategy, produced gene drive components that were maintained separately to prevent spreading, all within a secure setting.
Initial tests revealed significant suppression of malaria parasites collected from infected children, alongside successful gene replication for anti-malarial proteins. “We can now confidently assert this technology has field application potential,” states Christofides.
The forthcoming phase involves releasing mosquitoes that create anti-malarial proteins onto islands in Lake Victoria and monitoring their behavior in a natural setting. Rwetoijela notes that the team is conducting risk assessments and engaging local communities. “Thus far, political and public backing has been robust.”
The expectation is that gene drives will significantly contribute to the eradication of malaria in endemic regions. A. gambiae is the only species responsible for malaria transmission, and “gene drives could change the course,” claims Christofides.
Multiple organizations are also exploring gene drives for malaria control, alongside various strategies aimed at managing other pest populations.
Genetically modified mosquitoes have already been deployed in certain countries to manage wild mosquito numbers, but these strategies generally depend on continuously releasing high quantities of insects.
Google has announced a significant breakthrough in quantum computing, having developed an algorithm capable of performing tasks that traditional computers cannot achieve.
This algorithm, which serves as a set of instructions for guiding the operations of a quantum computer, has the ability to determine molecular structures, laying groundwork for potential breakthroughs in areas like medicine and materials science.
However, Google recognizes that the practical application of quantum computers is still several years away.
“This marks the first occasion in history when a quantum computer has successfully performed a verifiable algorithm that surpasses the power of a supercomputer,” Google stated in a blog post. “This repeatable, beyond-classical computation establishes the foundation for scalable verification and moves quantum computers closer to practical utilization.”
Michel Devore, Google’s chief scientist for quantum AI, who recently received the Nobel Prize in Physics, remarked that this announcement represents yet another milestone in quantum developments. “This is a further advancement towards full-scale quantum computing,” he noted.
The algorithmic advancement, allowing quantum computers to function 13,000 times faster than classical counterparts, is documented in a peer-reviewed article published in the journal Nature.
One expert cautioned that while Google’s accomplishments are impressive, they revolve around a specific scientific challenge and may not translate to significant real-world benefits. Results for two molecules were validated using nuclear magnetic resonance (NMR), akin to MRI technology, yielding insights not typically provided by NMR.
Winfried Hensinger, a professor of quantum technology at the University of Sussex, mentioned that Google has achieved “quantum superiority”, indicating that researchers have utilized quantum computers for tasks unattainable by classical systems.
Nevertheless, fully fault-tolerant quantum computers—which could undertake some of the most exciting tasks in science—are still far from realization, as they would necessitate machines capable of hosting hundreds of thousands of qubits (the basic unit of information in quantum computing).
“It’s crucial to recognize that the task achieved by Google isn’t as groundbreaking as some world-changing applications anticipated from quantum computing,” Hensinger added. “However, it represents another compelling piece of evidence that quantum computers are steadily gaining power.”
A truly capable quantum computer able to address a variety of challenges would require millions of qubits, but current quantum hardware struggles to manage the inherent instability of qubits.
“Many of the most intriguing quantum computers being discussed necessitate millions or even billions of qubits,” Hensinger explained. “Achieving this is even more challenging with the type of hardware utilized by the authors of the Google paper, which demands cooling to extremely low temperatures.”
Hartmut Neven, Google’s vice president of engineering, stated that quantum computers may be five years away from practical application, despite advances in an algorithm referred to as Quantum Echo.
“We remain hopeful that within five years, Quantum Echo will enable real-world applications that are solely feasible with quantum computers,” he said.
As a leading AI company, Google also asserts that quantum computers can generate unique data capable of enhancing AI models, thereby increasing their effectiveness.
Traditional computers represent information in bits (denoted by 0 or 1) and send them as electrical signals. Text messages, emails, and even Netflix movies streamed on smartphones consist of these bits.
Contrarily, information in a quantum computer is represented by qubits. Found within compact chips, these qubits are particles like electrons or photons that can exist in multiple states simultaneously—a concept known as superposition in quantum physics.
This characteristic enables qubits to concurrently encode various combinations of 1s and 0s, allowing computation of vast numbers of different outcomes, an impossibility for classical computers. Nonetheless, maintaining this state requires a strictly controlled environment, free from electromagnetic interference, as disturbances can easily disrupt qubits.
Progress by companies like Google has led to calls for governments and industries to implement quantum-proof cryptography, as cybersecurity experts caution that these advancements have the potential to undermine sophisticated encryption.
Researchers have crafted an environmentally friendly substitute for palm oil, potentially available by the end of 2025.
Palm oil, alongside other tropical oils like shea, coconut oil, cocoa butter, and soybeans, presents significant environmental challenges.
These oils encroach upon rainforests, contributing to deforestation, biodiversity decline, greenhouse gas emissions, as well as air and water pollution in regions such as Southeast Asia, South America, and Africa.
However, palm oil is prevalent in our foods and cosmetics. It is estimated that nearly half of all packaged goods in supermarkets contain palm oil, disguised under various ingredient names including glycerin and stearic acid.
This dilemma prompted a team of scientists at Bath University, led by chemical engineer Professor Chris Chuck, to seek alternatives for over a decade. Their research has led to a promising solution: a yeast called Metschnikowia pulcherrima.
“It thrives on grapes,” Chuck mentioned in BBC Science Focus. “It’s already applied in the organic wine sector. When you enjoy the blackcurrant notes in red wines from South Africa, that’s thanks to Metschnikowia.”
This yeast naturally comprises about 20% fat; however, Chuck’s team employed a method termed “directional evolution,” which promotes a rise in fat proportions, akin to selective breeding, by utilizing environmental pressures.
“Currently, about half of it is pure fat,” Chuck explained. “We didn’t just increase the yeast’s mass; it’s impressively fatty. Plus, we managed to accelerate its growth.”
The cultivation of this oil requires minimal space and uncomplicated equipment—just a large vat. The yeast feeds on food waste, such as discarded bread and potato byproducts, which are converted into sugar.
Once the yeast becomes densely populated, the cells burst and release oil, which is processed similarly to traditional cooking oils.
After this process, half of the non-oil yeast can be repurposed into other food ingredients, such as natural emulsifiers and beta-glucans, a heart-healthy fiber also found in oats.
By adjusting temperature, acidity, and sugar, yeast can produce a range of fats. The oil on the right is engineered to resemble more saturated, semi-solid palm oil, while the oil on the left is a less saturated liquid – Credit: Clean Food Group
Adjusting the yeast’s growing environment allows scientists to modify its flavor, texture, and nutritional properties, balancing saturation levels to mimic various fats.
“If executed correctly, we can prevent the destruction of tropical forests,” Chuck stated. “Currently, we’re using land equivalent to Argentina to cultivate cooking oil, making it one of the largest agricultural footprints globally.”
Demand for palm oil continues to rise. The current palm oil market is valued at $50.6 billion and is projected to increase to $65.5 billion (£48.3 billion) by 2027.
“We need forests to act as the planet’s lungs,” Chuck explained. “We cannot afford to clear everything.”
Moreover, substituting some tropical oils with yeast-based alternatives can lead to reduced greenhouse gas emissions.
“These tropical crops emit more CO2 than oil they produce,” Chuck added, noting that yeast-derived oils emit 95% less carbon dioxide and can be cultivated in nearly any location.
“These cutting-edge fermentation techniques enable us to establish local production,” he elucidated. “We’ve implemented this model on the outskirts of Birmingham, utilizing waste from our nearby factory to create oil and reintegrate it into our local ecosystem.”
This yeast-based oil is on the horizon; Chuck indicated it could debut in cosmetics by late 2025 or early 2026, with food applications to follow shortly thereafter.

A recent study by Professor Victor Pasco from Pennsylvania and his team reveals the method for determining the robust electric field associated with thunder, which collides with molecules such as nitrogen and oxygen, resulting in x-rays that trigger intense storms through additional electrons and high-energy photons.
NASA’s high-population ER-2 plane is equipped with instruments for the fly-eye Earth Intake Mapper Simulator and the Ground Gamma Ray Flash (ALOFT) Mission, which records gamma rays from ThunderClouds (illustrated in purple). Image credit: NASA/ALOFT team.
“Our research provides an accurate and quantitative explanation of the initial processes leading to lightning,” stated Professor Pasco.
“It connects the underlying physics of X-rays, electric fields, and electron avalanches.”
In their study, Professor Pasco and colleagues employed mathematical modeling to validate and elucidate field observations related to photoelectric phenomena within the Earth’s atmosphere.
This phenomenon, known as terrestrial gamma-ray flashes, consists of invisible, naturally occurring bursts of x-rays along with their associated radio emissions.
“By creating a simulation that mirrors the observed field conditions, we offered a comprehensive explanation of the x-rays and radio emissions occurring inside Thunderclouds,” added Professor Pasco.
“Our research illustrates how electrons, accelerated by lightning’s strong electric field, can generate x-rays upon colliding with air molecules like nitrogen or oxygen, leading to an avalanche of electrons that create high-energy photons to initiate lightning.”
Through their model, the researchers analyzed field observations gathered by various research teams utilizing ground-based sensors, satellites, and high-altitude surveillance platforms to simulate thunderstorm conditions.
“We elucidated the mechanisms of photoelectric events, the triggering conditions for electron cascades in thunder, and the sources of diverse radio signals detected in clouds preceding a lightning strike,” explained Professor Pervez.
“To validate the lightning initiation explanation, I compared our findings with previous models, observational studies, and my own investigations into lightning bolts, specifically intercompact cloud discharges that typically occur within limited regions of Thunderclouds.”
This process, termed photoelectric feedback discharge, models the physical conditions where lightning is likely to happen.
The equations employed to develop the model are available in the published papers, enabling other researchers to apply them in their own studies.
Besides elucidating the onset of lightning, the scientists clarified why ground-level gamma-ray flashes can often occur without the accompanying light and radio emissions that signify lightning in rainy conditions.
“In our simulations, the high-energy X-rays generated by relativistic electron avalanches create new seed electrons driven by photoelectric phenomena in the air, rapidly amplifying these avalanches,” Professor Pasco remarked.
“Moreover, while this runaway chain reaction is generated in a compact volume, it can happen across a varied range of intensities, often with minimal optical and radio emissions but detectable X-ray levels.”
“This explains why these gamma-ray flashes originate from regions that are visually dim and appear silent in wireless frequency.”
The team’s findings will be published in the Journal of Geophysical Research: Atmospheres.

Attention athletics fans, there’s an intriguing new competition to check out: Sperm Race.
It’s been reported that male birth rates are on the decline, with reduced sperm motility (movement speed) being a significant contributing factor. To raise awareness, a teenage founder has introduced sperm racing as a sport. As they say: “We’re creating the first racecourse for sperm: two competitors, two samples, one microscope finish line.”
Their site showcases “microscopic racetracks” that mimic reproductive systems, using “high-resolution cameras” to “track all microscopic movements.” They claim, “It’s all streamed live,” suggesting the phrase choice is deliberate, with the victor being “the first sperm to cross the finish line, confirmed via advanced imaging.”
The inaugural race on April 25th featured entries from two California universities. Readers may question why feedback on this topic emerged slowly. It’s due to a twist in the tale post-event.
Unfortunately for organizers, journalists like River Page, Reporter at Free Press, revealed that “the winner was predetermined. The ‘race’ was computer-generated.”
The issue is that microscopes can’t function that way. To have tracks long enough for sperm to swim competently, tracking them on camera is impractical. In film, a cameraman can follow Tom Cruise sprinting along the roof of a moving train. Yet, focusing a microscope can be challenging, even when the cells are nearly stationary.
The creators apparently ran a real race in a private setting, relying on computer-generated imagery to “depict” sperm racing for paying spectators.
This has led to speculation that a second round of the sperm race is improbable. I can’t help but recall how millions relish completely fabricated “sports entertainment” like wrestling, and outcomes in football often hinge on which teams have the wealthiest billionaires. Perhaps sperm racing could indeed be the next big sensation.
Water-Based Cooking
Feedback loves to explore the latest food trends, from cutting carbs to eating only lean meats, salt, and water! There’s even talk of “Air Protein,” which involves “microbial organisms that harness carbon dioxide.”
Essentially, water-based cooking means utilizing water for cooking whenever possible, in favor of oil. Think boiling, stewing, or steaming over stir-frying or roasting. This method reduces the formation of harmful advanced glycation end products (AGEs) found in the crispy bits of fried foods known to be linked to health complications. Hence, water-based cooking enthusiasts should steer clear of those.
Driving this trend is Michelle Davenport, a UCSF and NYU-trained nutrition scientist and the former founder of Digital Children’s Food Company. She educates followers on Instagram on how to manage metabolic health through water-based cooking inspired by family recipes.

Could a new approach lead to error-free quantum computers?
Nord’s numbers
Canadian startups in quantum computing assert that the new Qubit technology will enable the development of smaller, more affordable, and error-free quantum computers. However, reaching that goal presents a significant challenge.
Traditional computers mitigate errors by storing redundant copies of information across multiple locations. This method, known as redundancy, requires quantum computers to utilize many additional qubits, potentially hundreds of thousands, to replicate this redundancy.
Julianne Camiland Lemire and her team at Nord’s numbers have engineered a qubit that promises to reduce this requirement to just a few hundred. “The fundamental principle of our hardware is to utilize qubits with inherent redundancy,” she notes.
Competing qubit technologies include small superconducting circuits and ultra-cold atoms. The Nord Quartique qubit employs a superconducting cavity filled with microwave radiation. Inside this cavity, photons are trapped and bounce back and forth, allowing information to be encoded within quantum states.
This design is not entirely new; however, it’s the first instance of employing “multimode encoding.” Researchers utilize multiple properties of photons simultaneously to store information, thereby enhancing resilience against common quantum computing errors.
Victor Albert from the University of Maryland mentions that effective quantum error correction necessitates more qubits, meaning information is stored in interconnected groups rather than isolated qubits, safeguarding the system from individual failures.
The innovative Qubit incorporates a second technique that enables the effective storage of information in a four-dimensional mathematical framework.
This is why NORD’s quantitative project anticipates that their error-resistant quantum computers will be up to 50 times smaller than those utilizing superconducting circuit qubits, the most advanced yet. Moreover, the company estimates that machines built with their Qubits will consume as much power as those using conventional methods.
Despite these advancements, Nord has not yet released data on multiple kits. Furthermore, ensuring the multimode encoding functions correctly is still pending, indicating that the new Qubit has yet to be applied in computational tasks. Significant technical hurdles remain before these teams can achieve scalable quantum computing.
“It’s too early to conclude whether this fault-resistant approach will inherently outperform other methods,” remarks Barbara Telhal at Delft University of Technology in the Netherlands.
Michel Devoret from Yale University observes that while the new development is “not groundbreaking,” it enhances the science of quantum error correction and reflects the company’s grasp of technical difficulties.
Lemire expresses that the team is actively working on building additional Qubits and refining existing designs. They aim to implement a “perfect mechanism” for manipulating information stored within the Qubit, essential during quantum computational processes. The goal is to create a practical quantum computer featuring over 100 error-resilient qubits by 2029.
Known as Verve-102, this treatment could revolutionize heart attack prevention and significantly lower LDL cholesterol levels (often referred to as “bad” cholesterol) with a single injection.
While statins can achieve similar cholesterol reductions, they typically require daily administration.
“This is the future,” stated Professor Riyaz Patel, an academic from the University of London and a doctor at Barts Health NHS Trust involved in the trial – BBC Science Focus.
“This is not a fantasy; it’s reality. We are actively implementing it. I was providing this treatment to my patient during the exam.”
Unlike statins, which gradually lower cholesterol, Verve-102 aims for a one-time alteration by “turning off” a specific gene called PCSK9 in the liver. This gene is crucial in managing the levels of LDL cholesterol that the liver can detect and eliminate from the bloodstream.
In simpler terms, a reduction in PCSK9 means less LDL in the bloodstream.
“The results are stunning,” Patel remarked. “This drug disables a small segment of your DNA, and your LDL cholesterol will be permanently 50% lower thereafter. That’s a game-changer!”
Cholesterol builds up in blood vessel walls, leading to plaque formation that can obstruct blood flow.
Elevated LDL cholesterol levels heighten the risk of this buildup, prompting millions (over 40 million in the US and over 7 million in the UK) to take daily medications like statins for cholesterol management.
The VERVE-102 clinical trial included 14 participants with familial hypercholesterolemia, a genetic disorder that heightens the risk of heart disease, heart attacks, and strokes due to extremely high LDL cholesterol levels.
Initial outcomes from Verve-102 injections show that all participants reacted positively to the treatment with no severe side effects.
Responses varied by dosage. The lowest dose group experienced an average LDL reduction of 21%, while the intermediate group showed a 41% reduction, and the high-dose group saw a 53% reduction.
Remarkably, one individual in the high-dose group achieved a 69% reduction in LDL cholesterol after receiving Verve-102.
Dr. Eugene Braunwald, a distinguished medical professor and Hershey’s professor of medicine at Harvard Medical School who did not take part in the study, noted that the preliminary data is “promising” and indicates “the potential for a new era in cardiovascular disease treatment.”
Verve is actively recruiting participants for further stages of clinical trials involving even higher Verve-102 doses in the UK, Canada, Israel, Australia, and New Zealand. The final results are expected to be revealed in the latter half of 2025.

Kashiwara’s work is very abstract, but is seen as important
Peter Bagde / Typos1 / The Abel Prize
Red-tailed For his research on algebraic analysis, he received the 2025 Abel Prize, known as the Nobel Prize in Mathematics.
Professor of Kashiwara Kyoto UniversityJapan received the award “for his fundamental contributions to algebraic analysis and representational theory, particularly for the development of the theory of D-modules and the discovery of crystal bases.”
His work involves the use of algebra, focusing on investigating geometry and symmetry, and using those ideas to find solutions to differential equations that include the relationship between mathematical functions and their rate of change. Finding solutions to such equations can be particularly difficult, especially for functions with several variables, and therefore with several rates of change. These are known as partial differential equations (PDEs).
Kashiwara’s important work on the D-module, a highly specific area of algebraic analysis, including Linear PDE, was conducted surprisingly early in his career during his doctoral dissertation. He has worked with over 70 collaborators. Kashiwara said New Scientist He was pleased to win the Abel Prize, but he is still active and would like to make further contributions.
“I’m currently working on representative theory of quantum affine algebra and its related topics,” he says. “There’s a great guess: [the] “Affine epicenter speculation,” but I still don’t know how to solve it. ”
David Craven At the University of Birmingham, UK, Kashiwara’s work is very abstract and far from a direct real-world application, and even basic summary says that a minimum of a doctorate in mathematics is required. “That’s the level of these things being difficult,” he says. “It’s incredibly esoteric.”
However, Craven says that Kashiwara had a major impact on his field. “What he did is permeate theories of expression. If you want to do geometrical expression theory, you can’t escape from Kashiwara.
Gwyn Bellamy “All the big results on the field are [algebraic analysis] It was more or less due to him, and Kashiwara’s Abel Prize victory has been a long time.
Named after Norwegian mathematician Neils Henrik Abel, the Abel Prize is awarded annually by the King of Norway. Last year, Michelle Taragland won for his work in extreme studies of probability theory and randomness.
IIt's easy to believe that Elon Musk's reach is unlimited. But the richest people in the world are given a carte blanche to control the space satellite empire, own one of the biggest social media platforms, produce the world's bestselling electric cars, and gush the US government from Donald Trump, but there is a market where masks have not yet cracked properly.
Now, due to his new impact on the Trump administration and global geopolitics, Musk's entrance into the Indian market could be smoother and faster than expected, both on Tesla's electric vehicles and Starlink satellite internet.
When India's Prime Minister Narendra Modi traveled to Washington earlier this month to meet Trump, he sat down with Musk personally. There, according to the Indian government, the pair “discussed about strengthening collaboration with Indian and US organizations in innovation, space exploration, artificial intelligence and sustainable development.”
Trump said it more frankly: “I'm assuming him.” [Musk] I want to do business in India. ”
To date, India's 110% tariffs on imported electric vehicles have prevented Tesla from entering the fast-growing Indian market. However, Musk last year vowed that Tesla would be in India “as soon as possible as humanly possible.” And after his recent encounter with Modi, he appears to be keen to make it a reality.
Tesla has already started advertising for work in Mumbai and Delhi and has signed a lease to open its first showroom in Mumbai. If Tesla promises to invest $500 million in the factory that manufactures the car within three years, it could also take advantage of the new Indian government scheme, which will reduce import duties on electric vehicles to 15%. However, the tax credit only applies to the first 8,000 vehicles. This could push Tesla back.
The Tesla plant will benefit India, a country that is desperate for foreign investment and job creation, particularly in manufacturing. Nevertheless, Musk holds a checkered record of his commitment to investing in India. Last year, he left the Modi government's involvement after coming up with a high-profile plan to travel to India, hanging the possibility of a $3 billion investment to build a Tesla plant in the country, but cancelled the trip at the last minute. Instead, he rivaled China, another huge market that Musk would like to exploit in the same way to cut down on large transactions.

Tesla also faces tough competition with Indian manufacturers. Indian manufacturers manufacture and sell popular electric SUVs at about a quarter of the starting price of £35,000, which is far above the budget of most Indian families, when Tesla costs. (Tesla car sales have also plummeted worldwide, falling 45% in Europe in January.)
Trump also seemed less enthusiastic about Musk's ambition to start making Teslas in India. “If he builds a factory in India now, that's fine, but that's unfair to us. Trump told Fox News.
Another more advantageous finger in the Indian mask pie could be SpareLink's Starlink. Globally, masks already have the dominant lead on the satellite internet. There are more than half of all satellites in the sky.
Since 2021 he has been adamant about bringing Starlink into India. According to Deloitte, India's satellite internet currently has a small appetite, but is expected to grow to a $1.9 billion (£150 million) market by 2030, and is considered an important entry point for India's thriving telecom industry.
Earlier this year, after Trump took office, where Musk became very well-known, Indian Communications Minister confirmed that Starlink was in the process of seeking the security permits necessary to operate in India.
Jyotiraditya Scindia said: “If you check all boxes, you'll see the license. In their case [Starlink] Do it, we will be very happy. ”
However, in India, communications, including satellite internet, are one of the most strictly regulated and controlled industries in India, putting a huge obstacle in the way that foreign companies such as masks are allowed to have security permits.
In particular, Musk's close ties and business interests in China, and the use of Starlink in the Ukrainian War, was viewed as an insurmountable cybersecurity issue, SpareLink's ability to control access to satellite Internet from abroad. Government Undermody in India routinely orders internet providers to block important online content and uses internet blackout as a means of information management.
These fears could be raised after sources in Myanmar and neighboring India's Manipur state told the Guardian earlier this year that Starlink was already being used by the state's militant groups to avoid the regular internet closures imposed after the outbreak of ethnic violence.
A recent report from an Indian think tank warned that Starlink is a “wolf in sheep's clothing” and cited use by the US intelligence reporting agency and the military, and that it could be used to undermine India's safety.
However, some believe that after Trump's election, the Indian government may want to take those concerns to the side. “I think India had doubts about giving security clearance to Musk's Starlink before the US election results began,” said Nikhil Pahwa, founder of Indian tech news platform Medianama.
“One of the things we rely on India is our control of internet access and control over our operators. But now that Musk is part of the US government, his leverage in India has certainly increased, and it is possible that Starlink Clearing Security approval has improved dramatically.
Starlink can provide satellite internet to rural areas, but some have raised fears that it could be used to undermine India's safety. Photo: Nikolas Kokovlis/Nurphoto/Shutterstock
Pahwa said the Indian government's decision on Starlink is “as many political decisions as it is a security decision.”
What's known as “Starlink diplomacy” — opening the country to mask satellites in an obvious attempt to satisfy the Trump administration — was already evident in neighbouring Bangladesh, where the country's interim leader, Mohammed Yunus, suddenly expanded an invitation to launch Starlink within 90 days.
Even before Trump was re-elected, the Indian government had already piloted Starlink's ambitions in favour of its ambitions. In October, the government announced that broadband satellite spectra would be allocated administratively rather than auctions. “We will do our best to serve the people of India at Starlink,” Musk responded with an X.
This decision means Starlink has a much better opportunity to compete with Indian telecom companies in the fight to manage the country's satellite internet market. He has encountered rage from some of the country's biggest operators, including Jio, who also has vast ambitions in the satellite internet space, and has since lobbyed the government to reverse its auction decisions.
One of the main advantages of satellite internet is that it can provide internet access even in the most remote areas. However, in India, most people living in rural areas are unlikely to be able to afford it unless the subsidies are large.
Technology analyst Prasanto K Roy said that if Starlink cuts a significant amount of what he did in Africa, it could lead to a price war with India's biggest carrier if he repeats what Starlink did in the US at a price of around $10 compared to $120. A successful mobile internet, Jio came from undercutting all competitors to make Indian mobile internet the cheapest in the world, but could follow.
“Starlink isn't as easy in India like other markets, so there's a very strong competition here, so it's going to be difficult to get monopoly even at low prices,” says Roy.
He added: “People using Starlink will obviously be a very small niche at the top of the socioeconomic pyramid. But once he gets the hold, that's something that masks can really be utilized in India.”
In a groundbreaking scientific achievement, a mouse with two male parents has successfully reached adulthood.
Researchers utilized embryo stem cell engineering to accomplish this milestone by accurately correcting an important gene involved in reproduction. Double-headed mouse.
This innovative method has allowed scientists to overcome previously insurmountable barriers in reproducing single-identified mammals.
In previous experiments, using two male mice resulted in genetic issues during fertilization, leading to severe congenital defects and early termination of mouse embryo development.
However, the researchers of this new study suspected that these genetic issues were caused by “imprinted” genes, which are inherited from both male and female parents.
“The unique characteristics of imprinted genes have led scientists to believe they are the fundamental barriers to mammal reproduction,” said Research co-author Professor Qi Zhou.
“Even in the artificial creation of a two-cell embryo or double-headed embryo, they were unable to develop properly and stalled at a certain point due to these genes.”
Based on this theory, researchers altered 20 important imprinted genes using various methods before implanting the modified embryos into surrogate mothers.
Their findings revealed that these genetic edits not only allowed for the creation of double-headed mice but also enabled them to survive to adulthood.
“These discoveries offer compelling evidence that imprinted abnormalities are the primary barriers in mammals,” said co-author Professor Guan Zan Ruo from SUN YAT-SEN University.
“This approach greatly advances the manipulation of embryo stem cells and cloned animals, paving the way for progress in regenerative medicine.”
However, researchers noted that only 11.8% of surviving embryos successfully developed to birth, and some did not survive to adulthood due to developmental disorders.
In fact, most of the adult mice displayed abnormal growth and lifespan, and the surviving mice were infertile.
The team is actively working to address these issues by investigating whether altering a specific gene can improve embryo development. They also plan to extend their research to include larger animals like monkeys, though the use of this technology in humans remains uncertain.

Ion traps can control atoms for quantum experiments
Y. Colomb/National Institute of Standards and Technology/Scientific Photo Library
After decades of investigation, researchers observed a series of atoms undergoing a one-dimensional phase change. This was so elusive that it could only happen in a quantum simulator.
“There is only one motive [for our experiment] I'm trying to really understand basic physics. “We're just trying to understand the fundamental states that matter can be in,” he says. alexander shuckardt at the University of Maryland.
He and his colleagues used electromagnetic fields to arrange 23 ions of the element ytterbium in a line, forming a nearly one-dimensional chain. The device can be used for quantum computing, but in this case the researchers used the chain as a simulator instead.
In it, they built a 1D ytterbium magnet one atom at a time. Previous calculations predicted that this type of magnet would become unmagnetized when warmed, thanks to quantum effects. However, no experiments have achieved this phase transition in the past.
One reason for the difficulty is that systems such as quantum computers and simulators typically only work properly when they are very cold. So heating them to cause a phase transition can cause them to malfunction, Schuckert says.
To get around this, he and his colleagues tuned the initial quantum state of the atoms so that over time, the collective state of the 1D magnet changes as if the temperature were increased. This revealed a phase transition that had never been seen before.
The result is very unusual, he says, because chains of atoms are generally not supposed to undergo phase transitions. Mohammad Maghrebi at Michigan State University. The researchers were able to manipulate it precisely because each ion could interact with other ions over large distances, even if they weren't in contact. This caused the entire line to engage in abnormal collective behavior.
Because their simulator allows for such exotic states of matter, it could be used to study theoretical systems that are extremely rare or may not exist in nature, Maghrebi said. say.
Schuckert suggests that quantum simulators could also help explain the strange electrical or magnetic behavior that some materials exhibit in the real world. But for that to happen, these devices will have to be able to reach higher temperatures than they currently do. Currently, researchers can only create models at extremely low temperatures, but within five years it may be possible to simulate even higher temperatures, he says.
And if the simulator could be made larger, for example by arranging ions in two-dimensional arrays, many more existing theoretical systems could be studied, he says. andrea trombettoni at the University of Trieste, Italy. “This would suggest new physics to explore,” he says.
The US Congress is talking about extraterrestrial life again. But despite some evidence, this question remains frustratingly unanswered. Professor Michael Bolander, an expert on the impact of contact with extraterrestrial intelligence on human law, details newly released documents from the Department of Defense.

Stem cells are produced in the bone marrow and develop into different types of blood cells.
Katerina Conn / SPL/ Alamy
Human blood stem cells have been grown in a laboratory for the first time, which could dramatically improve how certain types of cancer are treated.
The lab-grown cells have so far only been tested in mice, but when injected into the animals, they resulted in functional bone marrow similar to levels seen after umbilical cord blood cell transplants.
Treating cancers such as leukemia and lymphoma with radiation and chemotherapy can destroy blood-forming cells in the bone marrow. A stem cell transplant means new healthy bone marrow and blood cells can grow. The umbilical cord is a particularly rich source of stem cells, but there is a limited amount they can provide, and the transplant may be rejected by the body.
The new method allows researchers to create stem cells from actual patients, eliminating supply issues and reducing the risk that the patient's body will reject the stem cells.
First, they transformed human blood and skin cells into so-called pluripotent stem cells through a process called reprogramming. “This involves temporarily switching on four genes, so that the patient's cells revert to an earlier stage of development that can become any cell in the body,” he said. Andrew Elefanti At the Murdoch Children's Research Institute in Melbourne.
The second step is to turn the pluripotent cells into blood stem cells. “You start by making thousands of tiny, free-floating balls of cells, each containing a few hundred cells, and then you induce them to turn from stem cells to blood vessels to blood cells,” Elefanti says. This process, called differentiation, takes about two weeks and produces millions of blood cells, he says.
When these cells were then injected into mice that lack immune systems, they produced functional bone marrow in up to 50 percent of cases. That means they made the same cells that carry oxygen and fight infection as healthy human bone marrow, Elefanti says. “This unique ability to make all blood cell types over an extended period of time defines them as blood stem cells,” he says.
Abbas Shafi A researcher from the University of Queensland in Brisbane said the work was an “exciting step forward” towards new treatments for blood cancers. “It's never been done before and has great potential for the future.” But even once animal testing is complete, he said a lot of human research still needs to be done before the technique can be used in the clinic.
Simon Cohn Researchers at Flinders University in Adelaide, Australia, say a key advantage of their approach is that it can be scaled up to produce “an essentially limitless supply” of blood stem cells, but they add that the work is based on blood or skin cells, and success rates and blood cell diversity depend on the starting cell type.
“This suggests that treatments are inconsistent even at the preclinical stage in mice, and will need to be addressed before clinical trials in human patients,” he says.
Those who suffer from the throbbing pain of migraines know how challenging everyday tasks can become. However, a new medication, if taken at the first signs of a migraine, could potentially prevent the onset of debilitating symptoms.
The drug, ubrogepant, has recently been approved for use in the US and is available in the UK, although not covered by the NHS. A study funded by AbbVie, the manufacturer of ubrogepant, revealed that taking the pill at the first indication of a migraine can prevent severe headaches from developing.
Before a migraine attack, some individuals experience early warning signs like sensitivity to light and sound, fatigue, neck pain, stiffness, and dizziness. Identifying these symptoms can help in timely treatment with ubrogepant to inhibit the protein CGRP in the brain responsible for migraines.
The research conducted by Dr. Richard B. Lipton and his team involved 518 participants who were able to predict the onset of migraines within a few hours. Those who took ubrogepant reported being able to function normally two hours after ingestion, with fewer limitations on their activities even after 24 hours.
While promising, ubrogepant may not be effective for those who experience sudden migraine attacks without warning signs. Regardless, experts view this development as a positive step in migraine treatment, providing hope for those who suffer from this common but debilitating condition.

Astrophysicists from the Event Horizon Telescope (EHT) Collaboration have conducted test observations that achieve the highest resolution ever obtained from Earth’s surface by detecting light emanating from the center of a distant galaxy at a frequency of about 345 GHz. When combined with existing images of the supermassive black hole at the center of Messier 87 and the Milky Way galaxy at a lower frequency of 230 GHz, these new results not only produce a 50% sharper picture of the black hole, but also a multi-color image of the region just outside the boundaries of these cosmic monsters.
This artist’s impression shows the locations of radio observatories on Earth that took part in the EHT Collaboration’s pilot experiment to produce the highest-resolution observations from the ground. Image courtesy of ESO/M. Kornmesser.
In 2019, the EHT Collaboration released images of M87*, the supermassive black hole at the center of Messier 87, and in 2022, they released images of Sagittarius A*, the supermassive black hole at the center of the Milky Way galaxy.
These images were obtained by linking multiple radio observatories around Earth, using a technique called Very Long Baseline Interferometry (VLBI), to form a single “Earth-sized” virtual telescope.
To get higher resolution images, astronomers typically resort to larger telescopes, or greater distances between observatories acting as part of an interferometer.
But because the EHT was already the same size as Earth, a different approach was needed to increase the resolution of ground-based observations.
Another way to increase a telescope’s resolution is to observe shorter wavelengths of light, and that’s exactly what the EHT Collaboration is currently doing.
“The EHT has seen the first image of a black hole at 1.3 millimeter wavelengths, but the bright ring created by the black hole’s gravity bending light still appears blurry because we’ve reached the absolute limit of how sharp an image we can make,” said Dr Alexander Raymond, an astronomer at NASA’s Jet Propulsion Laboratory.
“At 0.87mm, the images will be clearer and more detailed, which may reveal new properties, some previously predicted, but also some perhaps not.”
To demonstrate detection at 0.87 mm, EHT researchers carried out test observations of distant, bright galaxies at this wavelength.
Rather than using the entire EHT array, they used two smaller subarrays, including ALMA and the Atacama Pathfinder EXperiment (APEX).
Other facilities that will be used include the IRAM Thirty Meter Telescope in Spain, the Northern Extended Millimeter Array (NOEMA) in France, and the Greenland Telescope and Submillimeter Array in Hawaii.
In this pilot experiment, scientists achieved measurements down to 19 microarcseconds, the highest resolution ever achieved from the Earth’s surface.
But it hasn’t yet been able to capture an image: Though it has robustly detected light from some distant galaxies, it hasn’t used enough antennas to be able to accurately reconstruct an image from the data.
This technical test opens up new avenues for studying black holes.
With the full array, the EHT can see details as small as 13 microarcseconds, the equivalent of seeing a bottle cap on the Moon from Earth.
This means that at 0.87mm we can obtain images with approximately 50% higher resolution than the previously published M87* and Sagittarius A* 1.3mm images.
What’s more, it may be possible to observe a black hole that is more distant, smaller and fainter than the two black holes imaged so far.
“Observing changes in the surrounding gas at different wavelengths will help us solve the mysteries of how black holes attract and accrete matter, and how they can launch powerful jets that travel across the Milky Way galaxy,” said Dr Shepard Doleman, EHT founding director and astrophysicist at the Harvard-Smithsonian Center for Astrophysics.
This is the first time that VLBI technology has been used successfully at a wavelength of 0.87 mm.
“The detection of a VLBI signal at 0.87 mm is groundbreaking as it opens a new observational window into the study of supermassive black holes,” said Dr Thomas Krichbaum, astrophysicist at the Max Planck Institute for Radio Astronomy.
“In the future, the Spanish and French IRAM telescopes in combination with ALMA and APEX will allow us to image smaller and fainter radiation simultaneously at two wavelengths, 1.3 mm and 0.87 mm, which was previously possible.”
New Research has introduced an innovative and cost-effective method for diagnosing autism, potentially simplifying and speeding up the diagnostic process. Surprisingly, the new diagnostic test might involve analyzing stool samples rather than brain scans or psychiatric evaluations. Researchers have discovered consistent differences in the gut microbiome – the population of microorganisms in the intestine – between individuals with autism and those without.
Regularly collecting and analyzing stool samples could potentially enable doctors to identify autism at an earlier stage than current methods allow. This new approach is especially important given the diverse range of symptoms associated with autism, making diagnosis challenging.
“There is a pressing need to delay the diagnosis of autism in children, as the symptoms can vary widely,” according to the co-authors of the study. Professor Shu Qian Ng told BBC Science Focus.
Autism is a common condition, affecting approximately 1 in 100 individuals worldwide. While genetics is thought to play a significant role in autism, other factors such as birth complications, exposure to air pollution, and gender differences may also contribute.
Diagnosing autism currently relies on subjective behavioral assessments and developmental screenings, which can be time-consuming and depend on the availability of trained professionals. The average age of diagnosis in the United States is around 5 years old, resulting in delays in essential care and support for children with autism during crucial developmental stages.
The study, published in Nature Microbiology, analyzed stool samples from 1,627 children between 1 and 13 years of age, some of whom had autism. The researchers identified significant differences in gut bacteria between children with autism and those without, resulting in the identification of specific biomarkers for autism.
Utilizing machine learning algorithms, scientists could determine autism in children with up to 82% accuracy based on the biological function of several microorganisms in the digestive system. This innovative approach offers hope for a non-invasive and efficient diagnostic test for autism, expected to be available by the end of the year.

How is the gut microbiome linked to autism?
Dr. Ng explains two primary differences in the gut microbiome of individuals with autism compared to neurotypical individuals. Firstly, individuals with autism tend to have reduced diversity in their gut microbiome, with fewer types of bacteria and viruses. Secondly, children with autism often have an abundance of pathogens in their gut, potentially contributing to their condition.
The ongoing research aims to determine whether interventions such as dietary modifications or probiotics can help improve gut diversity and health, potentially influencing autism symptoms. Early indications suggest that adjusting the microbiome can lead to symptom improvements in children with autism.
While promising, the research does not establish causation between gut biomarkers and autism. Clinical trials are underway to explore the potential of using stool samples as a diagnostic tool for autism in young children.
The study participants were predominantly Chinese, highlighting the need for further global studies to enhance diagnostic accuracy across diverse populations. Despite potential dietary influences, preliminary findings suggest consistent diagnostic performance regardless of dietary habits.

All three discoveries were made in the past five years, and the more scientists experiment with animals, the more they discover that many species have an inner life and may be sentient. It shows that. A surprising range of organisms show evidence of conscious thought and experience, including insects, fish, and some crustaceans.
That’s why a group of top animal cognition researchers has released a new statement they hope will change the way scientists and society view and care for animals.
Nearly 40 researchers signed the petition. New York Declaration on Animal Consciousness” was first presented Friday morning at a conference at New York University. This comes at a pivotal moment, as a plethora of research on animal cognition collides with debates about how different species should be treated.
The declaration says there is “strong scientific support” that birds and mammals have conscious experience, and that there is a “realistic possibility” that consciousness exists in all vertebrates, including reptiles, amphibians, and fish. It has said. The possibility extends to many organisms without backbones, including insects, decapod crustaceans (including crabs and lobsters), and cephalopod molluscs such as squid, octopuses, and cuttlefish, he added.
“If an animal has a real possibility of conscious experience, it would be irresponsible to ignore that possibility in decisions affecting that animal,” the declaration reads. “We should consider welfare risks and use evidence to inform our responses to these risks.”
Jonathan Birch, professor of philosophy at the London School of Economics and principal investigator of the Fundamentals of Animal Senses project, is also one of the signatories of the declaration. He said many scientists had previously thought questions about animal consciousness were unanswerable, but the declaration shows his field is moving in a new direction.
“This has been a very exciting decade for the study of animal minds,” Professor Birch said. “People are boldly going out there in ways that have never been done before, and are excited about the possibility that animals like bees, octopuses, and squids are somehow having conscious experiences.”
From “automaton” to perceiver
There is no standard definition for animal perception or consciousness, but these terms generally refer to the ability to have subjective experiences, i.e. the ability to feel and map the outside world, and to feel emotions such as pleasure and pain. Refers to ability. In some cases, it may mean that the animal has some degree of self-awareness.
In this sense, the new declaration goes against long-standing orthodoxy in historical science. In the 17th century, French philosopher René Descartes argued that animals are nothing more than “material automatons” without souls or consciousness.
Rajesh Reddy, assistant professor and director of the animal law program at Lewis & Clark College, said Descartes believed that animals “cannot feel or suffer.” “There was something stupid and anthropomorphic about feeling sorry for them or empathizing with them.”
In the early 20th century, prominent behavioral psychologists promoted the idea that science should study only observable behavior in animals. rather than emotions or subjective experience.. But in the 1960s, scientists began to reconsider. Research began to focus on animal cognition, primarily other primates.
Birch said the new declaration attempts to “embody an emerging consensus that rejects the 100-year-old view that there is no way to study these issues scientifically.”
Indeed, there has been a recent surge in new discoveries that support the new declaration. As scientists develop new cognitive tests and test existing tests on a wider range of species, there are some surprises.
For example, consider the mirror mark test that scientists sometimes use to see if animals recognize themselves.
The fish were placed in an aquarium covered with mirrors, but no abnormal reactions were observed. However, when the cover was removed, seven out of 10 fish launched an attack toward the mirror, indicating that they may have interpreted the image as a rival fish.
After a few days, the fish calmed down and attempted strange behaviors never seen before in this species, such as swimming upside down in front of a mirror. Afterwards, some spent an unusual amount of time in front of the mirror observing their bodies. The researchers then placed brown spots under the fish’s skin to resemble parasites. Some fish tried to scrape off the mark.
“They’re able to see wrasse perform a series of steps that you can only imagine seeing in incredibly intelligent animals like chimpanzees and dolphins,” Birch said. “No one in a million years would have expected a small fish to pass this test.”
Birch said these experiments are part of a growing body of animal consciousness research over the past 10 to 15 years. “You have a much broader canvas to study a much wider range of animals, not just mammals and birds, but also invertebrates like octopuses and squid,” he said. “And people are talking about this idea more and more in relation to insects.”
Reddy said researchers may soon need to completely reorient their research, as more and more species are showing these signs.
A new legal perspective
Reddy said the change in scientists’ understanding of animal sentience could have implications for U.S. law, which does not classify animals as sentient at the federal level. Instead, animal-related laws primarily focus on conservation, agriculture, or the treatment of animals by zoos, laboratories, and pet retailers.
“The law moves very slowly and follows society’s views on many of these issues,” Reddy said. “This declaration, and other measures to remind the public that animals are more than just biological automatons, could greatly increase support for increased protections.”

State laws vary widely. Ten years ago, Oregon passed a law recognizing that animals are sentient and capable of feeling pain, stress and fear, forming the basis of progressive judicial opinion in the state, Reddy said. he said.
meanwhile, Washington and California These are among the states where lawmakers this year are considering bans on farming octopuses, a species in which scientists have found strong evidence of sentience.
British law has recently changed to consider octopuses as living organisms, just like crabs and lobsters.
“Once you realize that animals are intelligent, the concept of humane slaughter starts to become important. You have to make sure that the methods you’re using on the animals are humane,” Birch said. says. “For crabs and lobsters, very inhumane methods such as dropping them into a pot of boiling water are very common.”
Recent discoveries by scientists on the human gut microbiome, which consists of microorganisms like bacteria, archaea, fungi, and viruses residing in the gastrointestinal tract, may lead to new weight loss interventions in the future.
To be presented at the European Obesity Conference (ECO), researchers have identified specific microbial species that could either increase or decrease an individual’s risk of obesity.
Through a study involving 361 adult volunteers from Spain, scientists identified a total of six main species.
The lead researcher, Dr. Paula Aranaz, who obtained her PhD from the Nutrition Research Center of the University of Navarra, explained, “Our findings highlight the potential role of imbalances in various bacterial groups in the development and progression of obesity.”

Participants were categorized based on their body mass index: 65 were of normal weight, 110 were overweight, and 186 were obese. Genetic microbiota profiling was conducted to analyze the type, composition, diversity, and abundance of bacteria present in their fecal samples.
The study found that individuals with higher body mass index had lower levels of Christensenella Minuta, a bacterium associated with weight loss in other studies.
<.p>Interestingly, there were gender-specific differences in the findings. For men, the species Parabacteroides hercogenes and Campylobacter canadensis were linked to higher BMI, fat mass, and waist size. On the other hand, for women, the species Prevotella copri, Prevotella brevis, and Prevotella saccharolytica predicted obesity risk.
According to Aranaz, “Fostering certain bacterial types in the gut microbiota, like Christensenella Minuta, may protect against obesity. Future interventions aimed at altering bacterial strains or bioactive molecules levels could create a microbiome resistant to obesity.”
While the study focused on a specific region of Spain, factors such as climate, geography, and diet could influence the results. These findings could lead to tailored nutritional strategies for weight loss that take into account gender differences.

A new breakthrough in medical research could lead to personalized therapy for babies in the womb. Scientists have successfully grown small organs, known as organoids, from fetuses for the first time. This allows for monitoring the health of the fetus by cloning its organs.
Organoids are complex 3D models of organs made from human cells, retaining the DNA of the original cells, in this case, amniotic fluid cells. These organoids mimic human tissue and provide a more detailed view of any malformations compared to traditional imaging techniques like MRI or ultrasound.
Developed by researchers at UCL and Great Ormond Street Hospital (GOSH), this new technology enables a functional assessment of a baby’s congenital condition before birth. This groundbreaking method does not involve access to fetal tissue and is a significant advancement in prenatal diagnosis.
Lead author Dr. Mattia Gerli highlights the potential of organoids to revolutionize the pharmaceutical industry and clinics, particularly in fetal development. The study focuses on utilizing amniotic fluid cells to create organoids for prenatal medicine.
Growth process of mini organs
The process involves extracting cells from amniotic fluid, identifying tissue-specific stem cells, and culturing them to form organoids such as lungs, intestines, and kidneys. These organoids show similar functions and gene expressions to the corresponding organs.
In a study comparing organoids from infants with congenital diaphragmatic hernia to healthy infants, researchers found that treatments could be monitored at the cellular level. This breakthrough enables more information for parents during early pregnancy and expands research in fetal development beyond legal limitations.
Gerli emphasizes the potential of organoids in studying human development and advancing prenatal medicine. This innovation opens up a new field of research that was previously limited due to legal restrictions on fetal sampling.
The future of personalized therapy for babies in the womb looks promising with the use of organoids in medical research and fetal diagnosis.

Tardigrades are known for their ability to withstand extreme environments, and we now know how they do this. Small molecular sensors inside cells can detect when harmful molecules called free radicals are produced in excess, causing a state of dormancy.
Tardigrades, also known as tardigrades, are eight-legged microscopic invertebrates found throughout the world. Under adverse conditions such as sub-zero temperatures and strong radiation, the creatures shrink into a dry ball called a tongue and enter a deep hibernation state.
“Tardigrades do not breed under extreme conditions, but they can overwinter.” Derrick Colling At Marshall University in West Virginia. “We wanted to understand how they could step in there.”
To study, Kolling and colleagues exposed tardigrades to high levels of hydrogen peroxide, sugar, salt, or temperatures of -80°C (-112°F) to induce Tun. As a result of these stresses, tardigrades produce harmful, highly reactive molecules called oxygen free radicals.
The free radicals then go on to react with other molecules, team members say. leslie hix At the University of North Carolina at Chapel Hill. Importantly, the research team discovered that free radicals oxidize an amino acid called cysteine, which is one of the building blocks of proteins in the body. These reactions change protein structure and function and signal the onset of quiescence.
In experiments where cysteine oxidation was prevented, tardigrades were unable to enter the tun state. “Cysteine acts like a kind of regulatory sensor,” Hicks says. “This allows the tardigrade to sense its environment and respond to stress.”
When conditions improved, the researchers discovered that the cysteine was no longer oxidized and instructed the tardigrades to wake up from the tongue.
“Whether this is a universally conserved protection mechanism and whether this is conserved across tardigrade species is a really important question,” Hicks says. Her answers, she says, could help us better understand the aging process and how to make long-term space travel a reality.
Tinnitus, a ringing in the ears, can be a debilitating problem for those who suffer from it. However, a team of researchers has discovered a potential solution to this issue.
The survey results have been published in the magazine Frontiers of audiology and otology, and an international research team can effectively reduce symptoms in just a few weeks with an app that includes sound therapy and various training courses. The study involved 30 people with tinnitus, and almost two-thirds of them experienced “clinically significant improvement” from using the app. The team will now conduct a large-scale trial in the UK in collaboration with University College London Hospital. According to Suzanne Purdy, Waipapa Taumata Rau Professor of Psychology at the University of Auckland, New Zealand, cognitive behavioral therapy is known to help people suffering from tinnitus, but it is expensive and often difficult to access.
“[The app] Cognitive behavioral therapy, mindfulness, relaxation exercises, and sound therapy can be combined to train your brain’s responses and reduce tinnitus. The sounds you perceive fade into the background and become less noticeable.”
The new app aims to tune out the sound of tinnitus, giving the mind and body tools to suppress stress hormones and responses, and reduce the brain’s tendency to focus on the sound. The Mindear app is currently available for download for Apple and Android users. Some features are free in the app, but many are locked behind a paywall after a 7-day free trial (requires a £13 monthly subscription). Another app, the sound tinnitus app, is currently undergoing clinical trials in the UK.
About 1.5 million people in Australia, 4 million in the UK and 20 million in the US suffer from severe tinnitus, according to Dr. Fabrice Bardy, an audiologist at Waipapa Taumata Rau, University of Auckland, and lead author of the study published in the journal Frontiers of audiology and otology. He adds, “One of the most common misconceptions about tinnitus is that there’s nothing you can do about it; you just have to live with it. This is simply not true. Tinnitus Support Expertise The support of professionals with knowledge and expertise can reduce the fear and anxiety associated with a healthy patient experience.”
Tinnitus itself is not a disease, but is usually a symptom of another underlying health condition, such as damage to the auditory system or tension in the head and neck. While there is no known cure for tinnitus, management strategies and techniques can help patients. For more information, please visit the provided links.
