Scientists are exploring novel materials that efficiently absorb light across the solar spectrum to enhance solar energy harvesting.
Gold and silver nanoparticles have been identified as viable options due to their ease of fabrication and cost-effectiveness, yet current nanoparticles primarily absorb visible wavelengths.
To extend absorption into additional wavelengths, including near-infrared light, researcher Seungwoo Lee and colleagues from Korea University propose the innovative use of self-assembled gold superballs.
These unique structures consist of gold nanoparticles aggregating to form small spherical shapes.
The diameter of the superball was meticulously adjusted to optimize absorption of sunlight’s diverse wavelengths.
The research team first employed computer simulations to refine the design of each superball and predict the overall performance of the superball film.
Simulation outcomes indicated that the superball could absorb over 90% of sunlight’s wavelengths.
Next, the scientists created a film of gold superballs by drying a solution containing these structures on a commercially available thermoelectric generator, a device that converts light energy into electricity.
Films were produced under ambient room conditions—no cleanroom or extreme temperatures needed.
In tests using an LED solar simulator, the average solar absorption rate of the superball-coated thermoelectric generator reached approximately 89%, nearly double that of a conventional thermoelectric generator featuring a single gold nanoparticle membrane (45%).
“Our plasmonic superball offers a straightforward method to harness the entire solar spectrum,” said Dr. Lee.
“Ultimately, this coating technology could significantly reduce barriers for high-efficiency solar and photothermal systems in real-world energy applications.”
The team’s research is published in the journal ACS Applied Materials & Interfaces.

Green hydrogen offers numerous potential applications
Bernat Armangue/Associated Press/Alamy
Hydrogen, the most prevalent element in the universe, generates energy when it reacts with oxygen, producing only water as a by-product. This is why it is being hailed by politicians as a versatile solution to combat climate change, potentially powering the multitude of vehicles and industries that currently depend on fossil fuels.
However, 99% of the hydrogen in circulation today is “gray” hydrogen, derived from processes that decompose methane or coal gas, subsequently releasing carbon dioxide. To attain net-zero emissions, many nations are now pivoting towards “blue” hydrogen, which captures this CO2 before releasing it into the atmosphere, or “green” hydrogen, generated by using renewable energy to split water molecules.
UN Secretary-General António Guterres has remarked that green hydrogen represents a significant opportunity for Western nations to contend with China in the clean technology sector This was articulated at a press briefing on December 3rd.
The challenge is that low-carbon hydrogen costs at least double that of gray hydrogen. To boost production and reduce prices, government incentives are essential. While the European Union and others are backing the sector, former President Donald Trump has begun to dismantle proposed low-carbon hydrogen initiatives. This effort is ongoing in the US via a $7 billion initiative.
As a result of these obstacles, the analytics company BloombergNEF has revised its prediction for low-carbon hydrogen production down to just 5.5 million tonnes by 2030, amounting to around 5% of current gray hydrogen usage. Experts suggest that, given the limited availability of supplies, governments and organizations ought to concentrate on utilizing clean hydrogen where it is most beneficial for both the environment and the economy.
“Hydrogen can do nearly everything, but that doesn’t mean it should,” states Russell McKenna from ETH Zurich, Switzerland.
Recent studies conducted by McKenna and his team evaluated the CO2 emissions associated with producing and transporting low-carbon hydrogen for projects globally in 2000, contrasting it with the CO2 emissions this hydrogen could displace. Their findings indicate that hydrogen could significantly impact the climate in the manufacturing of steel, biofuels, and ammonia.
Conversely, employing hydrogen for road transport, electricity generation, and home heating sees limited emissions reductions.
Steel
In a blast furnace, coke made from coal serves the dual purpose of generating heat to melt iron oxide ore and supplying the carbon needed for chemical reactions that remove oxygen from the ore. Therefore, merely heating the metal using renewable electricity is insufficient. The reaction requires a carbon alternative, and hydrogen can produce water instead of CO2.
“The current technology allows for the production of iron from iron ore at an industrial scale without CO2 emissions, and that technology is hydrogen,” asserts David Dye from Imperial College London. “Any alternative would require substantial advancements in technology.”
Green steel startup Stegra is in the process of establishing a facility in northern Sweden, which aims to be the first carbon-neutral steel factory by the end of 2026, utilizing electric furnaces and green hydrogen generated from local river water. Similar projects are also being developed in Europe, Asia, and North America.
Nevertheless, generating green hydrogen and powering arc furnaces demands affordable renewable electricity. This year, the multinational steel producer ArcelorMittal declined a €1.3 billion subsidy aimed at transitioning two German steel mills to hydrogen, citing elevated electricity costs.
Ammonia
Crops require nitrogen in the form of nitrates to thrive, yet the soil contains limited nitrates. In the early 20th century, chemists Fritz Haber and Carl Bosch created a process that combines nitrogen, abundantly available in the air, with hydrogen to synthesize ammonia, which can then be transformed into various fertilizers.
This innovation fueled the agricultural revolution and the expansion of the global population, and today, hydrogen is primarily utilized in oil refining and ammonia production. Approximately 70% of all ammonia is used as fertilizer, while the remainder is employed in producing plastics, explosives, and other chemicals.
“You can’t electrify this… because it’s a chemical reaction requiring that input,” explains McKenna. “Thus, we need hydrogen, but it has to be decarbonized.”
Countries like Saudi Arabia are beginning to construct facilities that will leverage solar and wind energy to produce hundreds of thousands of tons of green ammonia, primarily for export. Simultaneously, a startup is working on compact, modular plants to generate green hydrogen and ammonia directly at US agricultural sites. However, at present, all these methods depend on governmental funding and tax incentives.
Alternative Fuel
Ammonia can also be burned in engines. While passenger vehicles and many trucks can efficiently operate on electricity, long-range transport methods, such as large trucks, ships, and airplanes, face challenges with battery storage and charging. Hydrogen holds potential as a key element in generating low-carbon fuels for this segment.
Research led by McKenna and his team has identified that manufacturing hydrotreated vegetable oils is one of the most advantageous applications of hydrogen. This involves treating used cooking oil with hydrogen to break down fats into combustible hydrocarbons.
Both ammonia and hydrotreated vegetable oil are being explored as substitutes for marine heavy fuel oil, which contributes to 3% of global emissions. The aviation sector, with a comparable carbon footprint, may also transition to ammonia.
Since hydrogen is produced independently of oil and closely resembles kerosene, it could also be harnessed to create synthetic aviation fuel compatible with existing aircraft.
In the long term, research teams at institutions like Cranfield University in the UK are conceptualizing aircraft featuring powerful tanks designed to store compressed hydrogen. Hydrogen and ammonia, which generate nitrogen oxide pollution when combusted, could alternatively be combined with oxygen in fuel cells, resulting in electricity and water. Ultimately, a fuel cell-powered aircraft represents a significant objective. Phil Longhurst from Cranfield University remarks.
“Hydrogen is the cleanest, zero-carbon fuel accessible, so it’s essentially the holy grail,” he concludes.
The rapid technological advancements can widen the gap between parents and teens. Gen
Moreover, a rise in cyberattacks affecting major companies has been frequently reported. Interestingly, many of those who face these hacks are young individuals equipped with advanced digital skills. In fact, the National Crime Agency reports that one in five children engages in unlawful activities under the Computer Fraud Act, which penalizes unauthorized access to computer systems or data. This statistic rises to 25% among gamers.
To combat this, co-ops adopt a unique preventive strategy. As part of our long-term mission to empower young people to harness their technology skills, Co-op has teamed up with a hacking game aimed at helping talented gamers secure positions in the cybersecurity sector.
This collaborative model is crucial because, as Greg Francis, former senior officer at the National Crime Agency and director of 4D Cyber Security, puts it, “A digital village is necessary to nurture digital natives.” Early intervention is essential, and parents play a pivotal role. “Parents are vital as they wield significant influence, but they shouldn’t remain passive. They should grasp the fundamentals of the hacker universe,” notes Francis, who also serves as Hacking Game’s Cyber Ambassador. So, where to begin?
Show Interest Without Judgment
First and foremost, having an interest in hacking isn’t inherently negative.
“Ethical hacking is an exhilarating and rapidly evolving domain, making it completely understandable for children to find it intriguing,” says Lynne Perry, CEO of children’s charity Barnardo’s. The organization collaborates with co-ops to generate funds to support young individuals in forging positive futures.
Maintaining an open dialogue is just as critical as beginning discussions early. “The ideal moment to start is now,” states Perry. “Once your child shows an interest in online technology, it’s time. Frequent, age-appropriate discussions are essential to keep the lines of communication open.”
Activities that seem innocuous can lead to a path towards cybercrime. Composite: Stocksy/Guardian Design
Perry advises involving children in online activities from a young age. “Explore technology together and discuss what to do if something unusual or concerning occurs. As kids mature, they may seek more independence, but regular interaction allows them to steer conversations, ask questions, and express concerns.”
For parents who grew up in a simpler digital age, grasping the complexities of today’s online gaming, dominated by franchises like Roblox, Minecraft, and Call of Duty, might seem daunting. However, both Francis and Perry emphasize that you don’t need to have all the answers to provide support.
Parents should check game age ratings and utilize parental controls, such as friend-only features, to enhance the security of in-game chats. For online resources, check Ask About Games for detailed information on popular games and guides to setting up safety measures.
It’s also beneficial to inquire if your young gamer has ever experienced being “booted” offline. Booting refers to a DDoS (Distributed Denial of Service) attack, where someone hacks another gamer’s IP address and floods it with data, causing an Internet outage. While booting may seem innocuous among gamers, it is a serious issue. Francis clarifies: “They may not realize this infringes on the Computer Misuse Act.” In fact, booting is identified as one of the initial steps towards cybercrime, as noted during Francis’s work with various prevention programs.
Asking questions aligns with observing potential warning signs like excessive gaming, social withdrawal, unexplained tiredness, unusual purchases of equipment or technology (especially if you’re unaware of how it was paid for), and multiple email addresses. While one sign alone might not be serious, a combination of them can be concerning.
Mary* faced these warning signs firsthand. “I had a son engaged in hacking on the darknet. He isolated himself and avoided sleep. I truly had no clue about his activities,” she shares. “After consulting a cybersecurity expert and discussing my challenges, I discovered he was attempting to delve into the cryptocurrency world on the darknet at just 13 years old.”

A Transformative Path for Neurodivergent Youth
Particularly for neurodivergent youth, engaging with games and spending time online can yield significant advantages in terms of socialization and emotion regulation. Yet, it’s crucial to recognize that with these benefits come potential drawbacks, including the considerable risks of internet or gaming addiction and the associated allure of cybercrime.
However, over 50% of technology professionals identify as neurodivergent, according to the Tech Talent Charter, indicating vast opportunities for neurodivergent young individuals in this sector. This is why The Hacking Games directly targets “digital rebels” showcasing “raw talent” and “unconventional thinking,” matching them with cybersecurity job opportunities, mentors, and fostering community through Discord group chats.
As Mary can confirm, mentorship and career awareness can be life-changing. “Cyber experts supported my son as a credible source of information and ultimately coached him on my behalf,” she states. “They helped him realize that he could channel his skills for impactful purposes. Consequently, he began assisting others.”
While this situation may seem alarming, there are numerous ways for parents to intervene positively. Approaching the subject with curiosity and care, rather than judgment, is paramount for guiding your child in the right direction. Here are some suggestions for parents who are concerned about their kids.
1 Begin conversations regarding online gaming safety early, approaching the topic with sensitivity rather than judgment. Remaining calm fosters open communication.
2 You don’t need to be fully informed, but a genuine interest can lead to insightful discussions. Ask your child about their games and online activities. Just as you would inquire about who they play with at a park, ask the same about their online friends. Be vigilant for warning signs like strangers trying to befriend them, offering freebies, or inviting them to unfamiliar worlds or games, as these could indicate grooming.
3 Take proactive measures. Pay attention to age ratings for games, which are significant. The best way to ascertain what is suitable for your child is to play the game together or at least observe them while they play. Remember, just like in Call of Duty, children can also be recruited in games like Minecraft. Games with community or “freemium” options can entice young players seeking extra income through in-game purchases or upgrades.
4 Monitor for warning signs such as social withdrawal, excessive gaming, lack of sleep, unusual tech purchases, and multiple email accounts.
5 Engage with your child’s school. Consult their computer science teacher to learn how they promote digital responsibility. Teachers often have insight into which students may require specific support to enhance their skills. This could serve as an early opportunity to channel their talents positively through initiatives like Cyber First and Cyber Choices or coding communities such as Girls Who Code.

In the media, the climate crisis can often seem overwhelming with daily warnings about environmental degradation and extreme weather events. However, how do climate scientists cope with the relentless reality of a shifting planet? What lessons can they share regarding the intense emotions that climate change provokes? Is there a way to leverage these feelings constructively?
New Scientist Recently, I spoke with New York-based climate scientist Kate Marvel and Tim Renton, a climate scientist at the University of Exeter, UK. Both have dedicated years to modeling the interactions of our planet in response to rising greenhouse gas levels in the atmosphere. Each has authored recent works that provide insights on how to engage with and address climate emergencies.
At first glance, their books may appear quite distinct. Humanity by Marvel comprises a series of essays delving into the emotional responses elicited by climate change. In contrast, Renton’s work, A Positive Turning Point, emphasizes actionable strategies and solutions. It argues compellingly that with appropriate social, economic, and technological interventions, a significant shift toward a cleaner world is achievable.
Nonetheless, both books center around accepting our feelings about climate change, enabling us to reshape our thoughts and actions. During our discussion, Renton and Marvel emphasized why we should embrace anger, fear, pride, and hope regarding our future on this planet.
Rowan Hooper: Kate, your book discusses nine emotional perspectives on our changing planet. Would you mind starting with anger?
Kate Marvel: The chapter on anger was one of the most straightforward for me to write. I aimed to explore the historical context of climate change discovery, particularly how it intertwines with the actions of those who misrepresent it.
For example, there’s a research team striving to show that the majority of excess carbon dioxide in our atmosphere originates from fossil fuel sources, conducting innovative experiments to confirm this. They’ve deployed large ships to gather sea measurements and ultimately they’ve constructed a climate model with highly accurate predictions. Interestingly, the story traces back to an oil company, which fills me with anger. They were aware of the truths that many are just beginning to confront.
RH: Can this anger drive positive action?
KM: That’s my hope. It can be easy to fall into a negative spiral fueled solely by anger. Social media often exacerbates this outrage, but that sort of unproductive rage doesn’t lead to meaningful change.
RH: Your book also addresses emotions such as wonder, guilt, fear, sadness, surprise, pride, hope, and love. Can you share your approach to navigating these emotions?
KM: It was important for me to convey that there isn’t a singular way to feel about climate change. I often grew frustrated by narratives that insinuate you must adhere to one emotion—such as fear or anger. Living on Earth means acknowledging conflicting feelings; you care deeply about what unfolds here because your loved ones do as well.
Tim Renton examines “tipping points” within ecosystems that could impact the broader climate scenario.
University of Exeter
RH: Tim, what strategies do you use to handle the emotions tied to climate change research?
Tim Renton: My focus has been on climate tipping points that could have serious implications, some of which are already beginning to manifest. For instance, up to five billion people globally depend on tropical coral reefs that are currently threatened.
Having studied this for nearly 20 years, I’ve had to cultivate a mental framework that grapples with complex systems while seeking evidence that fosters my optimism. It’s about finding plausible pathways toward necessary changes without falling into naive hope.
RH: Is it vital to strike a balance between realism and hope?
TL: Yes, that’s what I consider conditional optimism. I remain hopeful that as people read, they might join me on this journey. History shows us that meaningful inspiration comes from a handful of committed individuals.
Madeleine Cuff: Tim, much of your work revolves around the notion of tipping points. For those unfamiliar, can you explain what that entails?
TL: A tipping point refers to a moment when minor alterations result in significant impacts on systemic states and destinies. In the context of climate change, this includes major ice sheets, ocean circulations, and key biospheric aspects that can transition between stable states. For instance, the Amazon rainforest could shift into a degraded forest or savanna.
MC: What does a positive turning point look like?
TL: Drawing from various fields over decades, I’ve seen that social changes can reach a tipping point. Social protests can appear to ignite a revolution, and technological advancements can also lead to significant shifts. There’s a point when a new technology can effectively replace an existing one.
RH: A clear example is the rise of electric vehicles and the decreasing costs of solar energy. How do these contribute to a positive turning point?
TL: We need to focus on actions that facilitate positive tipping points. We must accelerate the decarbonization process significantly. Fortunately, everyone plays a role in this transition.
At the most basic level, adopting new behaviors like reducing meat consumption or embracing technologies such as electric vehicles and solar power is crucial. Most individuals have investment funds, so it is essential to scrutinize where these funds are allocated.
The narrative surrounding positive turning points often begins with passionate social activists and innovators who envision new technologies or those eager to create change.

MC: Kate, while we’ve touched on the negative emotions related to climate change, what about the positive feelings? How can they spur constructive actions?
KM: I began my book with a chapter on Wonder. When you take a step back to consider our planet and how much we understand it, it’s quite astonishing. This awe can forge connections and initiate conversations.
Typically, when I introduce myself as a climate scientist, people tend to disengage. But framing discussions around wonder can invite curiosity—for instance, asking, “Did you know that Earth’s water is likely older than our planet?” This fosters engagement. Utilizing a spectrum of emotions can be an effective communication strategy.
Research indicates that positively experienced emotions can be motivating. Pride in our achievements and the fulfillment of instigating change are significant. Social science data consistently points to love—love for family, friends, and community—as a powerful motivator for climate action. We all recognize the strength of such feelings.
My chapter on hope explores our complicated relationship with it. When asked if I hope for solutions to climate change, I compare it to asking if I hope to clean my bathroom; it’s not really a question of hope but a question of action we already know how to undertake.
As Tim rightly notes, many solutions are already at hand. We are making progress but need to increase the momentum to reach that critical turning point.
RH: We must confront our emotions, right? This might explain why so many struggle to engage with the issue—it can feel too immense to face.
KM: Absolutely. I ponder this daily, yet remain confounded by its complexity. The problem stems from global industrial activity, with CO2 and other greenhouse gases diffusing through the atmosphere and impacting life globally.
It’s daunting to distill such a vast issue into something easily digestible. The significance of what this entails and the actions required can span a lifetime of work.
Many Americans express concern about climate change and wish for governmental action. However, polls often reveal that individuals believe others are less concerned. One of the most impactful actions an individual can take regarding climate change is to discuss it openly. By talking about it, we begin to realize we are not alone.
RH: What do you hope readers will take away from your book?
KM: I want readers to explore how they can resonate with their communities through shared experiences and narratives.
TL: My goal is for readers to feel empowered to act on what might seem like a daunting and insurmountable situation, instilling a sense of agency instead.

Microorganisms may derive energy from surprisingly confined environments
Book Worms / Public Domain Sources from Aramie / Access Rights
Fractured rocks from earthquakes could reveal a variety of chemical energy sources for the microorganisms thriving deep beneath the surface, and similar mechanisms may feed microorganisms on other planets.
“This opens up an entirely new metabolic possibility,” says Kurt Konhauser, from the University of Alberta, Canada.
All life forms on Earth rely on flowing electrons to sustain themselves. On the planet’s surface, plants harness sunlight to create carbon-based sugars that are consumed by animals, including humans. This initiates a flow of electrons from the carbon to the oxygen we breathe. The chemical gradient formed by these carbon electron donors and oxygen electron acceptors, known as redox pairs, generates energy.
Underground, microbes also depend on redox pairs, but these deep ecosystems lack access to various solar energy forms. Hence, traditional carbon-oxygen pairings are inadequate. “Challenges remain in identifying these underground [chemical gradients]. Where do they originate?” Konhauser questions.
Hydrogen gas, generated by the interaction of water and rock, serves as a primary electron source for these microbes, much like carbon sugars do on the surface. This hydrogen arises from the breakdown of water molecules, which can occur when radioactive rocks react with water or iron-rich formations. During earthquakes, when silicate rocks are fragmented, they expose reactive surfaces that can split water, producing considerable amounts of hydrogen.
However, to utilize that hydrogen, microorganisms require electron acceptors to complete the redox pair. Attributing value solely to hydrogen is misleading. “Having the food is great, but without a fork, you can’t eat it,” remarks Barbara Sherwood Lollar from the University of Toronto, Canada.
Konhauser, Sherwood Lollar, and their research team employed rock-crushing machines to simulate the reactions that yield hydrogen gas within geological settings, which could subsequently form a complete redox pair. They crushed quartz crystals, mimicking strains in various types of faults and mixing the water present in most rocks with different iron and rock forms.
The crushed quartz reacted with water to generate significant quantities of hydrogen, both in stable molecular forms and more reactive species. The team’s findings revealed many of these hydrogen radicals react with iron-rich liquids, creating numerous compounds capable of either donating or accepting enough electrons to establish different redox pairs.
“Numerous rocks can be harnessed for energy,” Konhauser pointed out. “These reactions mediate diverse chemical processes, suggesting various microorganisms can thrive.” Secondary reactions involving nitrogen or sulfur could yield even broader energy sources.
“I was astonished by the quantities,” said Magdalena Osburn from Northwestern University, Illinois. “It produces immense quantities of hydrogen, and it also initiates fascinating auxiliary chemistry.”
Researchers estimate that earthquakes generate far less hydrogen than other water-rock interactions within the Earth’s crust. However, their insights imply that active faults may serve as local hotspots for microbial diversity and activity, Sherwood Lollar explained.
Importantly, a complete earthquake isn’t a prerequisite. Similar reactions can take place as rocks fracture in seismically stable areas, like continents or geologically dead planets such as Mars. “Even within these massive rocks, you can observe pressure redistributions and shifts,” she noted.
“It’s truly exciting to explore sources I was recently unfamiliar with,” stated Karen Lloyd from the University of Southern California. The variety of usable chemicals produced in actual fault lines is likely even more diverse. “This likely occurs under varying pressures, temperatures, and across vast spatial scales, involving a broader range of minerals,” she said.
Energy from infrequent events like earthquakes may also illuminate the lifestyles of what Lloyd refers to as aeonophiles—deep subterranean microorganisms thought to have existed for extensive time periods. “If we can endure 10,000 years, we may experience a magnitude 9 earthquake that yields a tremendous energy surge,” Lloyd added.
This research is part of a growing trend over the last two decades that broadens our understanding of where and how organisms can endure underground, states Sherwood Lollar. “The deep rocks of continents have revealed much about the habitability of our planet,” she concluded.

Music transcends mere entertainment; it serves as a remarkably effective tool for regulating mental states. Society must acknowledge the therapeutic potential of music, extending its use beyond clinical settings and into everyday life.
While it’s widely recognized that music can evoke emotions—lift our spirits, soothe our nerves, or bring us to tears—recent research from my lab at the University of Bergen in Norway reveals that it can also transform our thought processes. A 2019 study demonstrated that participants who listened to heroic or melancholic music while letting their minds wander experienced significant cognitive effects. The uplifting pieces invigorated participants and inspired positive thoughts, whereas somber music instilled calmness or ambition. This isn’t just a curiosity; it has real implications for mental health.
Research shows our minds wander frequently, with a Harvard University study indicating that we spend nearly half our waking hours in fantasy, often without improving our mood. Why? During these episodes, the brain’s default mode network (DMN) tends to dominate, fostering imagination and memory but also leading us into negative thought spirals—like worries at 3 AM or regrets about missed trains.
Recent brain imaging research indicates that negative daydreaming engages brain pain networks and the DMN, especially in conjunction with sad music. Specific brain areas, including the posterior sulcus, appear to play a crucial role in this connection. Such distressing thoughts activate neural circuits that are also engaged during physical pain.
Fortunately, the DMN has a natural counterpart—a cognitive executive network that facilitates focus and goal-directed behavior. These two systems are inversely correlated; when one is active, the other becomes subdued. Engaging with music can shift us into this more adaptive state, especially when we participate actively—whether by tapping along, matching our breathing to rhythms, or humming. This redirecting of attention helps to break negative thought cycles, providing our minds with a cognitive “reset.”
This approach doesn’t just elevate mood. A 2023 study found that individuals who tapped along to music reported a marked reduction in physical pain in their fingertips compared to those who simply listened. The combination of musical immersion and motor synchronization proved clinically beneficial in alleviating pain.
These insights point to musical engagement as a delightful form of meditation. Evolution may have shaped our brains to seek out music for precisely this reason: to enhance resilience and build social bonds.
I explore these concepts further in my new book, Good Vibrations: Unleashing the Healing Power of Music, which also offers practical techniques—such as music-centered breathing exercises and mood-enhancing playlists—to help regulate emotions, reduce anxiety, and alleviate negative thought patterns.
If music possesses such profound effects, it deserves far more recognition than being relegated to mere lifestyle accessory status. It should be woven into education systems, public health initiatives, and our daily routines. Music therapy must become more accessible, and music education—oftentimes the first to be cut in school budgets—should be viewed as essential for brain health, emotional intelligence, and social wellness.
Music is always within reach. The next time your thoughts begin to spiral or stress begins to encroach, resist the urge to check the news on your phone. Instead, turn to your favorite songs. Your mind—and your community—will be grateful.

“Technological advancements occur because they can,” states OpenAI CEO Sam Altman. I mentioned how the 2019 New York Times rephrased Robert Oppenheimer, the creator of the atomic bomb.
Altman encapsulates the ethos of Silicon Valley. The march of technology is relentless.
Another prevailing technical belief is that the emergence of artificial general intelligence (AGI) will result in one of two potential futures: a technotopia or the end of humanity.
In numerous instances, the arrival of humans has led to decisive change. We were faster, stronger, and more adaptable. Extinctions have often been unintended consequences of our ambitions. Genuine AGI could be akin to creating new species that may outsmart or outnumber us.
Altman and leaders of prominent AI labs are perceived as facilitators of a potential extinction event. This is a genuine concern echoed by numerous AI researchers and notable figures.
Given this backdrop, one naturally wonders: should we pursue technologies that could jeopardize our existence?
A common retort is that AGI is inevitable; it’s simply too appealing not to create. After all, AGI is viewed as the pinnacle of technology, as described by Alan Turing’s contemporaries, the last invention humanity will ever need. Moreover, if you don’t, someone else will. Responsibility looms overhead.
A burgeoning ideology in Silicon Valley, Effective Accelerationism (e/acc), argues that AGI’s inevitability is rooted in the second law of thermodynamics, and it is driven by “technological capital.” The e/acc manifesto asserts: “You cannot halt this machine. Progress is a one-way street. Returning is not an option.”
For Altman, e/acc is imbued with a mystical quality. The trajectory of inventions is perceived as an immutable law of nature. Yet, that perspective overlooks the reality that technology emerges from intentional human actions influenced by myriad powerful forces.
Despite the allure of AGI, the notion of technology being inevitable deserves scrutiny.
Historically, advancements in technology have prompted resistance, with society often restraining its utilization.
Concerns regarding new technologies have led to regulations. Pioneering biologists effectively prohibited recombinant DNA experiments in the 1970s.
Humans have yet to be successfully replicated through cloning, even though the possibility has existed for over a decade; only one scientist attempting to gene-edit humans found himself imprisoned.
Nuclear energy provides steady, carbon-free power, yet fears of disaster have inhibited its progress extensively.
If Altman was more aware of the history of the Manhattan Project, he might understand that the creation of nuclear weapons was a series of unpredictable and unintended outcomes, sparked by misconceptions regarding nations’ technological advancements.
It is now hard to conceive a world devoid of nuclear arms. Yet, in lesser-known history, President Ronald Reagan nearly reached an agreement with Mikhail Gorbachev to dismantle all nuclear arms, which was thwarted by the Star Wars satellite defense system. Currently, nuclear arsenals run at less than 20% of their 1986 peak.
These choices weren’t made in isolation. Reagan, previously a staunch opponent of disarmament, was ultimately swayed by the global movements advocating for nuclear freeze during the late 1980s.
While there are significant economic incentives to continue utilizing fossil fuels, climate activism has transformed the discourse surrounding decarbonization.
In April 2019, the youth-led climate movement Extinction Rebellion brought London to a standstill, pushing for net-zero carbon emissions by 2025.
The UK declared a climate emergency and Labor adopted a 2030 target for decarbonizing electricity production.
Sierra Club’s Beyond Coal campaign, while not widely recognized, has been incredibly effective, shuttering over a third of U.S. coal plants within five years.
In many respects, the regulation of AGIs could present an easier challenge than decarbonization, given that 82% of global energy production still relies on fossil fuels. Society does not depend on hypothetical AGIs to avert disaster.
Moreover, guiding the future of technological development does not necessitate halting current systems or creating specialized AIs to address pressing challenges in medicine and climate.
It’s evident why many capitalists are drawn to AI; they envision a future where they can eliminate manual labor (and reduce costs).
However, governments are not merely focused on maximizing profits. While economic growth is crucial, they also prioritize employment, social stability, market concentration, and occasionally democracy.
The overall impact of AGI on these areas remains uncertain. The government is not equipped for a scenario in which widespread technical unemployment occurs.
Historically, capitalists have often gotten what they desire, particularly in recent decades. However, their relentless chase for profit can hinder regulatory attempts to slow AI’s progression.
In a San Francisco bar in February, veteran OpenAI safety team members stated that E/ACC proponents should fear the likes of AOC and Senator Josh Hawley more than “extreme” AI safety advocates, as they possess the power to truly disrupt.
While humanity may seem stuck in its ways, it’s uncertain whether AGI will ultimately be created; however, proponents often assert that its arrival is imminent, and that resistance is futile.
Yet, whether AGI emerges in 5, 20, or 100 years is crucially significant. The timeline is more within our control than advocates are likely to admit. Deep down, many of them likely recognize this, rendering attempts to persuade others as futile. Furthermore, if they believe AGI is inevitable, why seek to convince anyone?
We already possessed the computational power to train GPT-2 a decade before OpenAI actually undertook it, as uncertainty loomed about its value.
Yet now, top AI labs fail to implement requisite precautions, even those that their safety teams advocate for. A recent OpenAI employee resigned over a loss of faith in responsible actions towards AGI due to competitive pressures.
The “safety tax” is a cost that labs are unwilling to incur if they wish to stay competitive, pushing for faster product releases at the expense of safety.
In contrast, governments do not face the same financial burdens.
Recently, certain tech entrepreneurs claimed that regulating AI development is impossible “unless you control every line of code.” While this might hold true for an AGI created on a personal laptop, cutting-edge AI requires extensive arrays of supercomputers with chips produced by an extraordinarily exclusive industry.
Thus, many AI safety advocates have proposed that computational governance could be a viable solution. Governments could collaborate with cloud computing providers to prevent unregulated training of next-gen systems. Instead of instituting draconian oversight, thresholds could be established to target only major players capable of significant expenditures; training models like GPT-4 reportedly cost over $100 million per run.
Governments must consider the implications of global competition and the risk of unilateral disarmament. However, international treaties can facilitate the equitable sharing of benefits derived from advanced AI systems while ensuring that comprehensive scaling does not proceed blindly.
Despite the competitive climate, collaboration among nations has occurred in surprising ways.
In the 1960s and 1970s, many analysts feared that all states capable of developing nuclear arms would do so. However, around three dozen nuclear programs have since been abandoned globally, not merely through coercion but via intentional actions bolstered by the norms established in the 1968 Non-Proliferation Treaty.
When polled on whether Americans favor superhuman AI, a significant majority indicated “no.” Opposition to AI has grown as technology becomes more prevalent. Advocates declaring AGI’s inevitability often dismiss public sentiment, perceiving the populace as unaware of their own best interests, which contributes to the appeal of inevitability as it bypasses meaningful debate.
The potential risks of AGI are severe, with implications that could jeopardize civilization itself. This necessitates a collective effort to impose effective regulations.
Ultimately, technology progresses because people choose to make it happen. The option to decide remains.
Counterterrorism officials have long assessed their approach to the utilization of terrorist organizations alongside digital tools and social media platforms, often likening their efforts to a whac-a-mole scenario.
Groups like the Islamic State and neo-Nazi organizations such as The Base harness digital tools to covertly gather finances, obtain 3D-printed weaponry, and disseminate these resources among their followers.
Over time, thwarting attacks and preserving an upper hand over such terrorist factions has progressed as more open-source resources have become accessible.
Currently, with artificial intelligence rapidly evolving, and now freely available as an app, security agents are in a race against time.
A source acquainted with the U.S. government’s counterterrorism initiatives informed the Guardian that several security agencies are deeply worried about how AI enhances the operational efficiency of hostile groups. The FBI refrained from commenting on the situation.
“Our research accurately forecasted the trends we are witnessing. Terrorists are leveraging AI to expedite their existing strategies rather than reinventing their operational frameworks,” remarks Adam Hadley, the founder and executive director of Tech Against Terrorism, an online counter-terrorism watchdog. He references the UN Anti-Terrorism Commission Secretariat (CTED).
“Future dangers encompass the potential for terrorists to utilize AI for rapid app and website development, essentially amplifying threats associated with pre-existing technologies rather than introducing entirely new categories of risk.”
So far, groups like IS and affiliated organizations have started to amplify their recruitment propaganda across diverse media formats, utilizing AI technologies such as OpenAI’s ChatGPT. This poses a more immediate risk as numerous sectors of employment prepare for potential upheavals, benefiting some of the wealthiest individuals globally while complicating public safety issues.
“Consider breaking news from the Islamic State. Today, it can be converted into an audio format,” states Mustafa Ayad, executive director for Africa, the Middle East, and Asia at the Institute for Strategic Dialogue. “We’ve observed supporters establishing groups to bolster their efforts, and we also have a photo array generated in the center.”
Ayad continues, aligning with Hadley’s insights: “Much of AI’s impact enables pre-existing methods. It also enhances their propaganda and distribution capabilities, which is critically significant.”
The Islamic State is not merely curious about AI; it actively acknowledges the potential benefits it offers, even providing encrypted channels with a “Guide to AI Tools and Risks” for its supporters. A recent propaganda magazine elaborates on the future of AI and the necessity for the group to incorporate it into their operations.
“It’s become crucial for everyone to understand the intricacies of AI, irrespective of their field,” the article states. “[AI] is evolving into more than just technology; it is becoming a driving force in warfare.” The writer even posits that AI services could serve as “digital advisors” and “research assistants” for any member of the organization.
Within the perpetually active chat rooms used for communication among followers and recruits, discussions are emerging on various ways AI could be utilized as a resource, though some remain cautious. One user queried whether it was safe to use ChatGPT for “explosives practices,” expressing uncertainty about whether authorities were monitoring the platform. Privacy concerns have surfaced as chatbots are increasingly utilized.
“Are there any alternatives?” an online participant asked among supporters in the same chat room. “Ensure safety.”
However, another participant discovered a method to evade attention during monitoring. By omitting schematics and instructions for creating a “basic blueprint for remote vehicle prototypes using ChatGPT,” they shifted focus. Truck ramming has emerged as a tactic in recent assaults, as well as for followers and operatives. In March, an IS-linked account released a video featuring AI-generated bomb-making tutorials utilizing avatars for crafting recipes from household materials.
Ayad emphasized that some of these AI-powered tools are advantageous for terrorist groups in enhancing their operational security, enabling them to communicate securely without attracting undue scrutiny.
Terrorist organizations continually strive to maximize and adapt digital spaces for their advancement, with AI representing the latest example. Since June 2014, when IS first commanded global attention amid dramatic live-tweeted accounts of mass executions in Mosul, they have undergone significant cyber operations. Following the establishment of their so-called caliphate, there was an organized response by both government entities and Silicon Valley to mitigate online presences. Western intelligence agencies have increasingly focused on encrypted messaging applications, particularly where 3D-printed firearms can be located, for surveillance and policing efforts.
Nonetheless, recent reductions in comprehensive global counterterrorism initiatives, including some from U.S. agencies, have undermined these efforts.
“The more urgent weakness lies in the deteriorating counterterrorism infrastructure,” Hadley remarked. “Standards have considerably declined as platforms and governments divert focus from this critical domain.”
Hadley is advocating for improved “content moderation” concerning AI-enabled materials, pressing companies like Meta and OpenAI to “enhance current mechanisms such as hash sharing and traditional detection methods.”
“Our vulnerabilities do not stem from new AI capabilities, but rather from the reduced resilience against established terrorist activities online,” he concluded.
Spider-like organisms dwelling near methane seepage seem to infiltrate the seabed, consuming microbes within their bodies that oxidize energy-dense gas. This discovery broadens the understanding of entities that rely on symbiotic associations with microorganisms in these alien settings.
Shana Goffredi from Occidental College, California, along with her team, has investigated marine arthropods named for their resemblance to ahinides, which thrive near three distinct methane seeps in the Pacific Ocean. They previously identified three new species from the sea spider genus Celico Sura, noted to be plentiful exclusively near these gas seepages.
In contrast, other sea spider species, which do not inhabit methane seep regions, primarily feed on various invertebrates. However, researchers have found that these newly identified sea spiders primarily acquire nutrition by ingesting a specific range of bacterial species residing in their bodies. These bacteria are capable of converting methane and methanol from the seepage into energy, something the sea spiders alone would not access.
Scientists observed that bacteria remained confined to the spiders’ exoskeletons, resembling “microbial fur coats,” and formed clusters that Goffredi describes as “volcanic-like.” The bacterial layer exhibited patterns resembling marks from a lawnmower, indicative of feeding by the spider’s robust “lips” and three tiny teeth.
To confirm that ocean spiders were actually consuming the bacteria, researchers employed radioactive labeling techniques to monitor the assimilation of methane carbon by laboratory sea spiders. “I observed methane being absorbed into the microorganisms on the spider’s surface, and subsequently traced carbon molecules migrating into the spider’s tissues,” Goffredi explains.
Researchers believe that ocean spiders do not consume all microorganisms growing on their exoskeletons. The species inhabiting the exoskeleton differ from those typically found in their surroundings, indicating a selection process is at play, Goffredi remarks. “The spiders are clearly cultivating and nurturing a unique microbial community.”
Sea spiders are not the first to cultivate microorganisms for chemical energy. “With every observation of these ecosystems near methane seeps, this phenomenon becomes increasingly evident,” notes Eric Cordes from Temple University, Pennsylvania. He previously collaborated with Goffredi on related studies, revealing a similar symbiosis in tube worms. The rich biodiversity near methane seepage is sustained not by solar energy but rather through methane and other chemicals. “That’s truly remarkable,” he remarks.
Cordes emphasizes that bacteria might also be transported along the surface of sea spiders. Unlike livestock on a farm, they gain superior protection and access to pastures. For instance, if methane seepage shifts to another area of the seabed, sea spiders could transfer bacteria to new locales. “Sea spiders maintain these organisms in an ideal habitat,” he adds.
aAnyone who saw the run that Tom Vickery uploaded to the sports-tracking app Strava on February 18th of last year might have been a little confused. The 30-minute sprint appeared to be taking place in the middle of the Channel, not far from Guernsey, toward the west coast of France. And, oddly enough, the run was in a straight line, as measured by a ruler, and was shown on Vickery’s public profile as a one-inch, unbending orange line within a blue swath of the app’s virtual ocean. Oh, and it was on world-record-breaking pace.
Of course, it probably came as no surprise to anyone who knows Vickery. The 38-year-old triathlon coach from Cambridge was on holiday to Bilbao for a two-day ferry trip, and this fairly fast jog was just one of almost four years of daily runs he had been recording on Strava at the time. Determined not to break the record on board, Vickery got up at 5am and spent his allotted 30 minutes sprinting up and down the deck. As the boat slid through the water, he appeared to be running faster than any long-distance runner in the world.
This is just one example of the lengths some people will go to to maintain a “streak.” A streak is something (actually anything) that continues uninterrupted over a period of time. It’s a form of gamification: the process of adding game-like elements to a task to make it more engaging. Perhaps the most famous “streak holder” is British runner Ron Hill, who ran every day for 52 years and 39 days (or 19,032 consecutive days), even going for a jog the day after breaking his sternum in a car accident in 1993.
Hill, a scientist, used to keep a diary of his runs, but more recently, advances in technology have made it possible to keep track of streaks in a more streamlined and user-friendly way. For example, on Snapchat, the word “streak” is part of the lexicon. A “snap streak” is the number of consecutive days that a user sends “snaps,” either photos or messages, to other users. To maintain a snap streak, a user must send a snap within a 24-hour period or the streak ends.
Foraging bees carry pollen from surrounding plants back to the hive
Eric Tourneret
If you’re lucky enough to find one, dip your fingers into a jar of honey from Pitcairn Island, a remote British Overseas Territory in the South Pacific. Honey is the island’s main export and highly prized among foodies. Pure and free of pesticides and pollutants, the honey infuses the delicious subtropical scents of Pitcairn Island plants, including passionflower, mango, guava and rose apple.
Honey contains much more information, if only we knew how to look for it. Breaking a container of honey opens a gateway to an entire ecosystem. Honey contains a detailed record of everything the bee encountered while foraging – not just the flowers that provided it with nectar and pollen, but also other plants, insects, fungi, viruses and larger animals in the environment.
He explains that honeybees are “passive bioaccumulators.” Parwinder Kaur As the bees go about their day, their fluffy bodies unwittingly collect samples of whatever they come into contact with, which then mix into the honey the bees produce, says researcher David Schneider of the University of Western Australia in Perth. “It’s got everything in it,” he says. Luca Fontanesi at the University of Bologna in Italy. “Well, almost everything.”
Scientists are now realizing that they have the potential to reach into that honey pot and garner sweet morsels of information that are currently hard to come by. Using advanced DNA tools, researchers are using honey to gather data on bee health, the general state of biodiversity in the bees’ foraging areas, and disease in the broader environment. They could identify possible culprits behind the mysterious Colony Collapse Disorder that is wiping out beehives, and…
From T-shirts with changing messages to carpets that can detect your position, the future of smart textiles seems to come straight out of a sci-fi novel.
Researchers now claim they have created a smart fiber that can achieve just that, without the need for a battery pack.
A team of Chinese researchers have developed textile-based electronics that utilize the human body as part of a circuit to harness electromagnetic energy from the environment.
This innovation could pave the way for a “body-bound” fiber electronics technology that functions without electronic chips or batteries and could be applied in various scenarios.
Co-author Chengyi Hou from Donghua University in Shanghai explained, “When electromagnetic energy passes through a fiber, it is converted into different forms of energy, including visible light or radio waves. Therefore, the fiber not only emits light but also produces an electrical signal when in contact with the human body.”
Hou highlighted that these radio signals are programmable by manipulating different aspects of the system, such as the fiber’s contact area with the body and its diameter.
The team stated that this method resolves a major challenge in integrating electronic systems into textiles, which is the necessity of rigid components.
Hou mentioned, “We have successfully achieved mass production of this new type of fiber electronics, which is as thin and soft as traditional fibers. The next step is to implement it.”
The team has created prototypes like a wearable cloth display with a cloth keyboard, intended for individuals with hearing impairments to aid in communication, as well as textile controllers for gaming.
Additionally, they developed a wireless tactile carpet that illuminates underfoot, providing emergency lighting at night and wirelessly transmitting signals to control household devices like lights.

Read more about the study here. The team assures that the fiber is constructed from three layers of inexpensive materials, making it durable, washable, and sweat-resistant.
An accompanying article suggests that this technology can also be utilized in robots, robotic prosthetics, and capturing haptic information to enhance human interactions and object recognition.
Dr. Luigi Occhipinti, a research director at the University of Cambridge specializing in smart electronics, biosystems, and AI, acknowledged the potential of this approach.
He stated, “By being constantly surrounded by various electromagnetic fields, we are developing innovative electronic textiles with skin sensors and unconventional electronics, powered uniquely through energy harvesting. This has the potential to unlock a new realm of self-powered wearable electronics for continuous health monitoring.”
Microscopic marine fungi are abundant, with approximately 2000 species discovered to date.
Dayarathne MC et al. (2020)
Take a walk along the coast almost anywhere in the world and you'll see colorful patches of life growing on rocks, seawalls, and driftwood. These are lichens, a mutualistic partnership between fungi and algae. In the UK, this may include brightly colored orange marine lichens and yellowish coastal sunburst lichens, as well as many other Drabber species.
Lichens are typically thought of as terrestrial organisms, and in fact, the majority grow inland on rocks, tree trunks, leaves, and soil. However, coastal organisms are not creatures that accidentally washed ashore from land; they are marine-adapted species found only on or in close proximity to shores. Until recently, they were considered to be outliers in the almost entirely terrestrial fungal kingdom. No more. “Fungi are present in every marine ecosystem we observe,” says Michael Cunliffe of the University of Plymouth in the UK.
Research on marine fungi is currently rapidly increasing, but their exact role and importance in marine ecosystems remains a mystery. Nevertheless, there are high hopes that it could save us from the two great scourges of the 21st century: antibiotic resistance and plastic pollution.
What are marine fungi?
The existence of marine fungi has been known for many years. The earliest descriptions were published in his mid-19th century to his early 20th century, but these were largely ignored by mainstream mycologists. Most of the species discovered are found on the roots of seaweed that live near the coast.
Dengue fever is currently endemic in 100 countries, putting half of the world’s population at risk. The threat has increased dramatically, with the number of dengue fever cases increasing tenfold between 2000 and 2019, and the number of cases hitting an all-time high in 2023.
Bangladesh, Peru and Burkina Faso have all seen record outbreaks in the past 12 months, while France, Italy and Spain have also reported cases of mosquito-borne dengue fever.
What’s causing this? Scientists say global warming is making space more hospitable to insects, and that climate change is fueling the rise in this mosquito-borne viral disease. As mosquitoes become more common, we expect the time to outbreak of dengue fever to shorten and the transmission season to lengthen.
This is a worrying situation.But that’s what the sponsoring team decided world mosquito program There is a possible solution. They suggest treating mosquitoes with bacteria that can prevent the development of viruses in the body.

What are the symptoms of dengue fever?
There’s a good reason dengue fever has been labeled “breakbone fever.” 80% of cases are asymptomatic, but when symptoms develop, symptoms include high fever, muscle and joint pain, severe headache, pain behind the eyes, nausea, and vomiting.
Symptoms begin 4 to 10 days after infection and can last from 2 days to up to a week. DHF (severe dengue fever) manifests as severe abdominal pain, persistent vomiting, bleeding gums or nose, blood in the stool or vomit, pale, cold skin, and fatigue. Doctors can only alleviate these symptoms because antiviral drugs are not available.
How does dengue spread?
Dengue fever is spread through the bite of an infected female mosquito. Aedes aegypti, typically found in tropical and subtropical regions. Originating from the forests of West Africa, Aedes aegypti They spread around the world during the African slave trade and have continued to hitchhike as a means of human transportation ever since.
other Aedes Other species can also transmit dengue fever, although to a lesser extent. The highly invasive Asian tiger mosquito is the likely cause of dengue infections in Europe. Unlike malaria mosquitoes, which usually bite at night and can be prevented with insecticide-treated bed nets, dengue mosquitoes bite during the day and are very difficult to control.
Mosquitoes are now highly urbanized creatures, admirably adapted to coexist with humans, their preferred blood source. In cities, stagnant water is key to survival, providing spawning grounds and habitat for aquatic larval and pupal development. Mosquitoes breed in small puddles in garbage, used tires, and man-made containers such as flower pots. Thus, humans have been the main driving force behind the success of the dengue mosquito.
How can we fight the spread of infection?
Dengue prevention requires a multipronged attack on mosquitoes, with a focus on insecticide spraying. However, insecticide resistance is developing in mosquito populations around the world, threatening their effectiveness.
what else? Control strategies also include adaptations to eliminate breeding sites or prevent reproduction. Aedes aegypti Prevent spawning in stagnant water (remove debris that could trap water and install covers on water storage containers).
Bacterial toxins are also applied to bodies of water to kill mosquito larvae. These strategies are labor intensive because it is difficult to identify, treat, and eliminate all breeding sites. Therefore, new methods of mosquito control are desperately needed.
The World Mosquito Program (WMP) has devised a non-chemical and non-GMO-based approach for dengue control. Bacteria called Wolbachia which occurs naturally in many insect species; Aedes aegypti.
WMP was found to be “infected”. Aedes aegypti and Wolbachia Prevented the onset of dengue virus in adult women. From a logistical point of view, this method is self-sustaining. Wolbachia It can spread to wild populations because it infects eggs through mating.
WMP reports a significant decrease in dengue cases. Aedes aegypti carry Wolbachia has been released.given that Aedes aegypti Since Zika and Chikungunya viruses are also transmitted, WMP has developed a potential “three-for-one” method of disease control.
It’s no exaggeration to say that mosquitoes are the most hated insects, but despite their notoriety, only a handful of the 3,500 species of mosquitoes transmit disease. They are also important to the ecosystem.
Mosquitoes are a food source for fish, frogs, reptiles, bats, and birds, and they are also pollinators, as male insects suck nectar from flowers (only females drink blood). The WMP approach is species-specific and targeted only. Aedes aegyptiThis is in contrast to the “blunt force” approach with insecticides, which can affect insects other than the target.
The climate change trajectory we are currently on is leading to rising temperatures and changing rainfall patterns, which will benefit this terrifying little insect and her viral cargo. Therefore, we need as many weapons as possible in our arsenal to combat the growing global dengue threat.
Immune system researchers have designed a computational tool to improve pandemic preparedness. Scientists can use this new algorithm to compare data from very different experiments and more accurately predict how individuals will respond to disease.
“While we are trying to understand how individuals fight off different viruses, the advantage of our method is that it can be applied to other organisms, such as comparing different drugs or different cancer cell lines. It has general applicability in academic settings,” says Dr. Tal Einab. D., La Jolla Institute of Immunology (LJI) assistant professor and co-leader of the new study.
This study addresses a major challenge in medical research. Labs that study infectious diseases collect very different types of data, even those that focus on the same virus. “Each dataset becomes its own independent island,” he says Einav.
Working closely with Dr. Rong Ma, a postdoctoral fellow at Stanford University, Einav set out to develop an algorithm to help compare large datasets. His inspiration comes from a background in physics, where scientists can be confident that their data falls within the known laws of physics, no matter how innovative the experiment. E is always equal to mc2.
For example, researchers may be able to design better vaccines by understanding exactly how human antibodies target viral proteins.
The new method is also thorough enough to give scientists confidence behind their predictions. In statistics, a “confidence interval” is a way to quantify how certain a scientist’s predictions are.
“When people from different backgrounds come together, there is great synergy,” says Einab. “With the right team, we can finally solve these big unsolved problems.”
