Recent findings from a comprehensive randomized trial indicate that natural ovulation methods for preparing the uterus for frozen embryo transfer after in vitro fertilization (IVF) are equally effective and come with fewer risks compared to traditional hormone therapy.

Emerging data suggests that for women with strong responses to IVF treatment (which can yield multiple eggs), freezing embryos and transferring them in a later cycle can enhance success rates. Consequently, frozen embryos now represent the majority of embryo transfers conducted globally.

Post-IVF, the crucial timing for transferring frozen embryos into the uterus occurs during the menstrual cycle when the endometrium (the uterine lining) is adequately thick to facilitate implantation.

Women can opt for either a medicated cycle, which involves administering estrogen and progesterone for uterine preparation, or a natural cycle, where the body’s natural hormone production is monitored, assuming regular cycles.

Determining the optimal choice remains complex due to a lack of substantial trials evaluating the complications linked to these varying methods.

To address this uncertainty, Daimin Wei and a team from Shandong University in Jinan, China, conducted a large-scale clinical trial involving 4,376 women across 24 fertility treatment centers. All participants were aged 20 to 40 and were slated for a single frozen embryo transfer. Participants were divided equally between the medicated and natural cycle groups.

“This is the randomized controlled trial we’ve been waiting for,” remarks William Bucket from McGill University in Montreal, Canada, who was not involved in the study.

Live birth rates were comparable between both methods, with 41.6% in the natural cycle group and 40.6% in the medicated group. This suggests that natural ovulation is as effective as hormone therapy for preparing the uterus for embryo implantation.

However, an analysis of maternal complications during and after pregnancy revealed notable distinctions.

Women utilizing natural cycles exhibited a lower likelihood of preeclampsia, a severe condition marked by elevated blood pressure, along with fewer incidences of early pregnancy loss. They were also less prone to develop placenta accreta spectrum, a condition that makes the placenta difficult to detach following childbirth. Additionally, this group had reduced rates of cesarean sections and severe postnatal hemorrhage.

“These risks impact both maternal and fetal health during pregnancy and hold significance for long-term postpartum health,” states Wei.

“This research is vital,” notes Tim Child, Chair of the Scientific and Clinical Progress Advisory Committee of the UK Human Fertilization and Embryology Authority. The clinic now advises individuals with regular menstrual cycles that both natural and medicated methods yield similar success rates.

However, Child points out that there is evidence suggesting natural cycles may lower the risk of preeclampsia. This reduction may be attributed to the presence of the corpus luteum, which regulates hormones necessary for preparing the uterus for pregnancy.

“This extensive study corroborates and expands on previous findings, especially concerning significantly lower rates of preeclampsia, early miscarriage, placenta accreta, cesarean sections, and postpartum hemorrhage linked to the natural cycle approach,” Child asserts.

Wei’s team is set to analyze blood samples gathered during the trial to identify potential biomarkers that could shed light on the differences observed in pregnancy complications.

Sinking Arctic Ocean Trees: A Natural Solution to Removing 1 Billion Tons of CO2

Trees Floating Towards the Arctic Ocean

Trees Floating Towards the Arctic Ocean

Logging extensive areas of boreal forests and submerging the trees in the Arctic Ocean could potentially eliminate up to 1 billion tons of carbon dioxide from the atmosphere each year.

Researchers suggest cutting down wildfire-prone coniferous trees and transporting them through six major Arctic rivers, including the Yukon and Mackenzie, where they can sink within a year.

“Currently, we have forests that sequester significant carbon, but the next challenge is finding ways to store it without burning,” says Wolf Bungen from Cambridge University.

To combat carbon emissions from hard-to-electrify industries, it’s essential to explore methods for atmospheric carbon reduction. While direct air capture technology is costly, tree planting can backfire if the trees end up dying or burning.

Several companies are working on wood burial techniques. For instance, a U.S. initiative, Running Tide, sunk 25,000 tonnes of wood chips off Iceland’s coast but faced shutdown due to environmental concerns.

Approximately 1 trillion tonnes of carbon are stored within the wood, soil, and peat of boreal forests across North Eurasia and North America, a figure expected to rise as climate change accelerates plant growth. However, with increasing wildfire frequency, this carbon could be released.

Bungen and his team previously discovered that wood can survive for up to 8,000 years in cold, oxygen-limited Alpine lakes without decomposing or emitting CO2. Six Arctic rivers transport substantial amounts of logs, with driftwood in deltas estimated to contain over 20 million tons of carbon. Carl Stadie from Germany’s Alfred Wegener Institute was not part of the study.

If every year, 30,000 square kilometers were cleared along each river, placing the wood on river ice in winter and then replanting, it could absorb up to 1 billion tons of CO2 annually, researchers estimate.

However, some US rivers continue to experience biodiversity loss a century after timber removal, warns Ellen Wall of Colorado State University.

“Dumping a massive amount of logs into a river resembles pushing brush into a river,” she notes.

Moreover, if wood becomes lodged on beaches or in tributaries, causing flooding, it could thaw permafrost and increase methane emissions from microorganisms.

“We could see a scenario where the wood aids ocean carbon sequestration, while onshore flooding and melting snow cause carbon release at high altitudes,” warns Merritt Turetsky from the University of Colorado Boulder.

Inadequate cold or oxygen-free conditions may lead to wood decomposition rather than sinking. Driftwood frozen in sea ice is often transported to the Faroe Islands.

“In a worst-case scenario, vast forest areas could be cleared, impacting the carbon they store,” says Stadie.

Roman Dial, a professor at Alaska Pacific University, warns that this proposal may be exploited by commercial logging and could face criticism from all sides of the political spectrum.

“How extensive is the list of potential unintended consequences that could unfold in the Arctic, given our limited understanding?” he questions.

Some regions of the Arctic ocean floor might not be suitable for conservation, according to Morgan Raven at the University of California, Santa Barbara. However, others could benefit from exploration, given the substantial influx of wood into the Arctic and other oceans. The Earth once experienced a greenhouse climate era 56 million years ago.

“We can investigate sediments and rocks to understand how this experiment was conducted in the past,” Raven concludes.

CAR-T Cell Therapy: A Natural Approach to Revitalizing Aging Intestinal Health

The Importance of a Strong Intestinal Lining for Optimal Health

Shutterstock/3dMediSphere

As we age, the cells that line our intestines gradually lose their ability to regenerate, impacting our immune health. However, recent research has successfully reversed this decline in older mice using genetically modified immune cells.

This innovative approach, known as CAR T-cell therapy, is primarily used to target specific blood cancers. It entails collecting a patient’s T cells, reprogramming them in a laboratory to identify and eliminate cancerous cells, and then reintroducing them into the bloodstream. Emerging variations of this therapy show promise not only in combatting solid tumors but also in preventing arterial blockages and treating autoimmune diseases like lupus.

In a groundbreaking study, Cemil Beyaz and his team at Cold Spring Harbor Laboratory, New York, explored the application of this therapy for revitalizing the aging gut. They focused on targeting damaged cells, known as senescent cells, which accumulate over time, fail to proliferate, and secrete substances that exacerbate inflammation and promote further aging. The researchers aimed their intervention at a protein called uPAR, prevalent on aging cells.

“The decline in gut health we observe with aging is linked to diminished stem cell fitness responsible for renewing the intestinal lining every three to five days,” Beyaz states. “We posited that eliminating these ‘unfit’ senescent cells would enhance the regenerative ability and overall functionality of stem cells in older mice.”

To validate this hypothesis, the researchers engineered CAR T cells from older mice to specifically recognize and eliminate uPAR on senescent cells. Upon reintroducing these modified cells, the researchers noted a significant increase in both the activity and number of stem cells maintaining tissue function, reaching levels comparable to those observed in younger mice. The treated older mice also exhibited marked improvements in intestinal barrier integrity and reduced inflammation compared to a separate cohort that received CAR T-cell therapy targeting different mechanisms.

“By removing senescent cells, we not only inhibited the aging process but also witnessed a reversal, with tissues displaying characteristics similar to those of young mice,” said team member Corina Amor, also from Cold Spring Harbor Laboratory.

“This therapy could potentially reverse age-related declines in bowel function, decreasing vulnerability to diseases such as intestinal infections, compromised intestinal integrity, and even cancer,” explained Tuomas Tammera from Memorial Sloan Kettering Cancer Center, who was not part of the study. However, he emphasized that ensuring the treatment’s effectiveness and safety in humans remains crucial.

Onur Eskiokaku, a researcher at Cold Spring Harbor Laboratory, highlighted the importance of determining the optimal dosage before advancing to human trials. “While uPAR is abundant in aged, defective cells, it may also be present in healthy tissues under certain conditions,” he noted.

It’s important to remember that senescent cells aren’t all detrimental; they play roles in tumor suppression and wound healing. “We are investigating the implications of depleting uPAR expression in other tissues,” mentioned Jesse Poganic from Harvard Medical School.

Additionally, treating aging in otherwise healthy individuals is not commonplace. The complexity and expense associated with CAR-T therapy, coupled with ongoing safety concerns, suggest that widespread application for reversing aging effects is not imminent, according to Joanna Neves at the Center at King’s College London. “Safety standards for preventative treatments must be more stringent than those for oncology.”

Beyaz asserts that addressing the age-related decline in intestinal function has long posed a challenge, with no effective solutions currently available, especially when the intestinal barrier’s regenerative capability is compromised. This research marks a significant step forward, indicating that the removal of unfit cells can restore crucial functions.

Ways to Reset Your Body’s Natural Sleep Cycle

Feeling fatigued is the new norm

Experiencing reduced focus, appetite, and coordination? These are all indicators of sleep deprivation, a growing global issue.

About two-thirds of adults globally are estimated to awaken at least once each night. In the UK, one in five adults frequently struggle with sleep issues. As reported by the European Journal of Public Health, the UK is the most sleep-deprived nation in Europe.

A 2025 independent survey by OnePoll, commissioned by Silentnight, asked 2,000 UK residents about their sleep routines. The results showed that 24% of participants consider feeling tired to be normal.

This is a serious concern. Sleep deprivation not only impacts your mood the next day but can also lead to various health issues, as well as chronic physical and mental health challenges over time.

Discover why your body requires a nightly reset with valuable insights and tips for enhancing your sleep quality from Kathryn Pinkham, founder of Insomnia Clinic and sleep expert at Silentnight.

Please reset your mind


While you’re asleep, your brain actively resets itself for recovery. The glymphatic system clears out toxins and metabolic byproducts, while short-term memories are stored in the neocortex. Concurrently, the prefrontal cortex manages emotional responses, processes the day’s events, and prepares for what’s to come.

The brain also experiences a neurochemical reset as dopamine and serotonin levels drop notably during sleep. Brain waves slow down to the REM stage, where activity surges as the brain processes emotions and memories, aiding creative thinking during waking hours.

Kathryn shares tips on how to calm your mind before bedtime to effectively reset it.

• Alleviate stress by jotting down thoughts to relieve pressure.

• Instead of thinking, “I can’t sleep,” tell yourself, “I will get some rest, and I’ll manage the day.”

• Be gentle with yourself; don’t chase after ideal sleep. Reducing pressure allows your body to relax naturally.

Reset your body


During deep (slow wave) sleep, your body undergoes a reset and regeneration process. It’s recognized that sleep quality impacts the aging process, and chronic sleep deprivation can adversely affect both current and future health.

While you sleep, your body is hard at work. Protein synthesis fosters cell repair, the pituitary gland produces human growth hormone (HGH) to encourage muscle growth, and immune functions are enhanced.

During deep sleep, heart rate slows, blood pressure decreases, and your cardiovascular system rests. Quality sleep is shown to improve insulin sensitivity, enhancing glucose metabolism and energy levels. Hormones like melatonin are produced while cortisol, a stress hormone, is regulated.

Kathryn Pinkham advises on how to reset your body before sleep:

“The human body inherently needs sleep, a need that intensifies the longer you remain awake. Going to bed early, waking up late, napping during the day, or worrying excessively in bed can weaken this need, making it more challenging to fall asleep. To bolster your need for sleep, try going to bed a bit later and maintaining a consistent wake-up time. This way, you’re more likely to drift off as soon as your head touches the pillow.”

Reset your lifestyle


The Sleep Foundation states, “Good sleep is a 24-hour process,” indicating that cultivating productive daily habits is key to enjoying healthy sleep patterns.

“When you’re fatigued, it’s easy to fixate solely on bedtime,” Kathryn notes. “However, don’t depend only on sleep to feel rejuvenated. Other strategies for boosting energy include physical activity, ample sunlight exposure, and healthy eating. Simple adjustments like these can help your nervous system relax and alleviate stress. When your days are balanced, you’ll naturally start to sleep better.”

Silentnight’s national sleep reset campaign aims to encourage individuals in the UK to rethink their approach to rest, helping to eliminate obstacles to improved sleep through a structured three-step reset plan.

Findings from sleep reset research indicate:

1 in 3 people (30%) wake up multiple times each night.

• The main concerns keeping people awake include: Health worries (34%), Financial issues (28%), and Relationship troubles (23%).

• Nearly 30% of individuals lie awake regretting their actions from the day.

• Significant life events can also interrupt sleep, like Job interviews (30%), Moving (23%), and for 28% of women, menopause.

Silentnight provides a range of mattresses tailored to every sleeper, from our new UltraGel™ collection, designed for comfort and support throughout the night, to our Just Sleep roll-up mattress series, which combines convenience with comfort.

Senate Democrats Aim to Reinstate NOAA Database Monitoring $1 Billion in Natural Disasters

Senate Democrats are working to reinstate a database that monitored billions of dollars in climate and weather-related disasters for decades, which was discontinued by the Trump administration this past May.

Since 1980, NOAA has kept a disaster database for events causing damages over $1 billion in the U.S., but the agency halted its initiatives this spring due to budget cuts in climate science research under the Trump administration.

The database and its annual reports shed light on how climate change is influencing extreme weather patterns, including increased travel to flood-prone areas and rising wildfire incidents. Lawmakers have utilized the report in assessing disaster funding while raising awareness about natural disaster costs.

In a statement to NBC News in May, a spokesperson from NOAA indicated that the closure of the database was “consistent with evolving priorities and staffing changes.”

Currently, Senate Democrats, led by Peter Welch, D-Vt., have introduced a bill that mandates NOAA to revive the database and update it at least biannually. Congress holds the power to dictate NOAA’s budget and outline its administrative functions.

Welch stated, “Our legislation is crucial to reversing the reckless actions of the Trump administration, restoring this database, and mitigating the expenses associated with emergency preparedness and natural disasters. This database is essential for understanding the financial implications of constructing homes, businesses, and communities nationwide after significant weather events.”

Neither the White House nor NOAA has provided a response to requests for comments.

More than a dozen senators have co-sponsored the bill, including Sen. Angela of Brooks and Chris Van Hollen, who represents Maryland, where NOAA is based.

This legislation may face uphill battles in becoming law as Republicans, who hold the Senate, are not supporting the bill.

The introduction of this new bill reflects mounting concerns and protests regarding funding at NOAA and other climate-focused organizations. Notably, NOAA’s database has seen leading scientists resign, with some leaving the agency in May due to the planned closure of the database. One of them, Smith, has since joined Climate Central, a nonprofit research organization dedicated to climate change, to continue the work he once conducted at NOAA.

Tom Di Liberto, a spokesperson for Climate Central, indicated that the organization has refrained from commenting on current policies or proposed legislation.

“We look forward to enhancing our in-house $1 billion disaster dataset,” Di Liberto noted in an email.

From 1980 to 2024, NOAA’s database has recorded a staggering total of $40 billion in disaster-related expenses. In the previous year alone, NOAA reported $27 billion in disasters, amounting to around $182.7 billion in costs. This year ranks as the second-lowest for reported multi-billion dollar disasters since 2023.

The analysis provided “direct costs” of disasters, encompassing damage to buildings, infrastructure, and crops. However, it did not factor in other important considerations, such as loss of life, health-related costs from disasters, or economic impacts on “natural capital,” including forests and wetlands, as detailed in a 2025 report from the Congressional Research Service.

NOAA adjusts its data annually to account for inflation.

Previous Reports highlight that developments in hazardous areas vulnerable to floods, wildfires, and other natural disasters have intensified over time, leading to an increase in both the number and cost of weather and climate disasters, ultimately raising the number of at-risk assets.

Moreover, climate scientists assert that extreme weather events are occurring more frequently. Climate change is raising temperatures, heightening the risks of heat waves, intense precipitation, and rapidly intensifying hurricanes.

NOAA has utilized a combination of private and public data to generate estimates, integrating information from the Federal Emergency Management Agency, the U.S. Department of Agriculture, National Fire Centers, as well as private insurance data.

Like NOAA, these institutions are also experiencing budget cuts.

Bipartisan Backing Grows for the Natural Disaster Review Committee

As Texans look for solutions to flooding issues in the hill country, prominent meteorologists and policymakers are advocating for the creation of a disaster review board similar to the National Traffic Safety Commission, which investigates all civil aviation incidents and significant traffic occurrences.

The proposal for an independent committee to evaluate weather-related disasters is not a recent idea; however, it seems to have gained renewed momentum following floods in Texas that have claimed over 120 lives and left another 170 unaccounted for.

During a Senate confirmation hearing on Wednesday for the head of the National Oceanic and Atmospheric Administration (NOAA), Neil Jacobs expressed his support for the initiative when Sen. Ted Cruz (R-Texas) inquired about how he would enhance public response to emergency weather notifications.

“We also need more data and need to conduct post-storm evaluations,” Jacobs stated. “I have been involved with some aviation incidents at the NTSB, and we’re looking at something similar here, requiring data to identify what went wrong, whether proper warnings were issued, and how to respond to weather-related disasters.”

Lawmakers from both parties have taken the initiative.

Senator Brian Schatz and Rep. Bill Cassidy (R-La) have introduced multiple bills since 2020 to establish the Natural Disaster Safety Commission, modeled after the NTSB. Rep. Katie Porter (D-Calif.) and several Republican colleagues also introduced a corresponding bill in the House.

In 2022, the House of Representatives passed legislation that included provisions for creating a Natural Disaster Safety Committee; however, it failed in the Senate.

The proposed legislation aimed to establish a board consisting of seven independent members vested with subpoena power to conduct investigations. This would identify the fundamental causes of disaster impacts without assigning blame.

Cassidy and Schatz did not respond immediately when asked whether they feel there is renewed momentum in Congress for establishing a disaster review panel. Notably, Porter is no longer serving in Congress.

In a communication to NBC News, the only meteorologist in Congress, Rep. Eric Sorensen (D-Ill.), indicated he is collaborating with colleagues to initiate an NTSB-style program to investigate severe weather events.

“It would be incredible if meteorologists had access to research reports that could inform their future actions, regardless of past mistakes,” Sorensen remarked.

Illinois also faced significant flooding this week, with around five inches of rain descending in just 90 minutes at Garfield Park on Chicago’s west side, leading to multiple rescue operations.

The floods in Chicago and Texas were among four extreme rainfall events occurring within a week, events researchers describe as once-in-a-thousand-years occurrences.

The notion of an independent disaster review board has circulated within meteorological and disaster management circles for years. Mike Smith, a meteorologist and former senior vice president at Accuweather, has championed this concept since the aftermath of Hurricane Sandy in 2012.

Common “Natural Beauty” Ingredients That Harm the Planet

The beauty industry often resists trends. From campaigns on aging to home LED masks, consumers have encountered a range of innovations. However, one particularly enduring trend over the last decade is the shift towards “natural” or “organic” beauty products.

At first glance, this sounds appealing: fewer plant ingredients, minimal processing, and no synthetic pesticides. What could be wrong with that? The reality is more complex.

Choosing “natural” beauty products may feel like a wise choice when considering our planet.

Yet, as the beauty industry comes under scrutiny for its environmental impact, we must move beyond greenwashing and evaluate whether relying on naturally grown resources is truly sustainable within a billion-dollar industry.

Growth Market

The global natural and organic beauty sector is currently seeing robust growth driven by heightened consumer interest, with projections estimating gross revenues of approximately £11.3 billion ($14.9 billion) by 2025.

In the UK alone, the natural cosmetics market is expected to reach around £210 million ($278 million) in 2025, with annual growth rates of about 2.74% over the next five years.

From ingredient-light serums to zero-waste shampoo bars, the diversity and volume of products available have never been greater. While this thriving market is exciting, it also presents challenges.

More products lead to increased material extraction, mining, and synthesis, as well as greater packaging and emissions throughout the supply chain.

This intricate situation can easily confuse well-meaning consumers, who may get caught up in labels like “natural” or “organic” without fully understanding their implications.

There’s a common belief that if something is labeled “natural,” it must be beneficial for the environment. However, whether it’s Moroccan argan oil or Mexican aloe vera, obtaining natural ingredients often comes at a high price.

Crops require extensive land, water, and energy for cultivation.

Many high-demand crops are susceptible to climate change and, regrettably, are often linked to unethical labor practices. While we aspire for organic farming to represent a more sustainable approach, it can also lead to unintended negative outcomes.

For instance, many organic agricultural practices may yield lower crop outputs while occupying more land. This can result in deforestation as farmers seek additional land to maximize production of slowly-growing crops.

Naturally derived pesticides used in organic agriculture can also harm the soil.

Copper sulfate, commonly used in the wine industry’s “Bordeaux mixture,” has long been approved for use in organic farming but has recently faced regulation due to its negative effects on soil microbiomes and potential threats to local insect populations.

Lab-grown Materials

This is where biotechnology enters the conversation. While it may not have the allure of “Wild Harvest Lavender,” biotechnology could ultimately prove to be one of the planet’s most eco-friendly resources.

In simple terms, biotechnology utilizes scientific methods (often involving fermentation with yeast, plant sugars, or bacteria) to cultivate ingredients in laboratories, as opposed to sourcing them from nature. Think of it like brewing beer, but instead of a refreshing pint, you yield powerful active ingredients for moisturizers and shampoos.

These lab-generated components are molecularly identical to their natural counterparts and can be produced without ecosystem emissions, using significantly less water, land, and energy.

This highly controlled process can also be scaled efficiently while maintaining consistent quality.

For example, swapping “wild harvested lavender” for biotechnologically produced lavender essential oils can lead to substantial reductions in energy and water usage.

Producing 1g (0.04oz) of natural lavender oil requires about 20L (approximately 5 gallons) of water and about 4 megajoules of energy—roughly equivalent to watching TV for 20 hours.

In contrast, if biotechnologically produced, the same 1g can potentially require just 2-5L (0.5-1.3 gallons) of water and 1 megajoule of energy (the equivalent needed to boil a kettle).

Biotechnology has advanced significantly in recent years, although companies have yet to replicate every component of these unique essential oils.

One ingredient successfully replicated is bisabolol, known for its soothing properties in the cosmetics field. It’s utilized in a diverse range of products, from hormone-related creams to sun care and baby products.

To extract natural bisabolol, it must be derived from Candea trees native to Brazil. This cultivation can lead to deforestation, biodiversity loss, and ecosystem strain, with natural harvest quality varying based on weather conditions.

To obtain 1kg (2.2 pounds) of natural bisabolol, cutting down around 1-3 trees is necessary, with each tree taking 10-15 years to mature.

To create one ton (2,204 pounds) of bisabolol, approximately 3,000 to 5,000 trees are needed—a staggering statistic given the global demand is around 16 tons (35,000 pounds) annually.

Each tree consumes about 36,000 liters (9,500 gallons) of water over its lifetime (equivalent to 72,000 500ml bottles) and 75 megajoules of energy (approximately analogous to charging a smartphone 2,500 times).

Givaudan, a Swiss ingredient manufacturer, has already developed bisabolol through biotechnological means, resulting in a much higher specification than what natural agriculture can achieve.

Comparatively, biotechnological yields of bisabolol can utilize 90-95% less water and 50-60% less energy than natural Candeia tree yields, not to mention the hectares saved from potential deforestation.

Brands like Boots and Estée Lauder are investing in biotechnology.

Even smaller indie brands are beginning to highlight fermented or lab-grown ingredients. Eco Brand Biossance uses a similar moisturizing ingredient to squalene, but instead of harvesting it from shark fins, they derive it from sugarcane, claiming to save an estimated 20-30 million sharks each year.

Moreover, biotechnology ingredients tend to be purer, more stable, and often more effective than their natural counterparts, meaning your product will last longer, perform better, and evoke less guilt regarding the environment.

What Should I Look For?

For consumers, all this information can feel daunting, especially with packaging filled with misleading marketing buzzwords. However, here are a few straightforward tips for choosing cosmetic products that align with your values.

  • Seek out biotechnology or lab-grown ingredients, often labeled as “fermented origin,” “biodesign,” or “bioidentical” on ingredient lists.
  • Be cautious of common marketing greenwash terms like “eco-friendly,” “clean beauty,” “sustainable,” and “biodegradable.” Look for tangible values, timelines, or explanations backing these claims.
  • Avoid brands that shift their focus away from sustainability to other concerns, such as “opposing animal testing,” which has been banned by the EU since 1998 for British cosmetics.

While the notion that beauty should be “natural” is comforting, this approach isn’t necessarily the most sustainable choice, especially as the UK lacks a legal definition of what “natural” cosmetics entail.

If you genuinely want to protect the planet for future generations, it’s essential to move past the notion of nature as an infinite resource and start supporting smarter scientific innovations that collaborate with nature rather than oppose it.

Nature Memories Review: A New Book Reveals the Critical Shortcomings of Our Natural History Museum

What are you missing? Contemplating the exhibition at the American Museum of Natural History in New York City

Nature’s Memory
Jack Ashby (Allen Lane)

In his intriguing new book, Nature’s Memories: Behind the Scenes of the World’s Natural History Museum, Jack Ashby, assistant director of the University Zoology Museum in Cambridge, UK, describes the museum as a peculiar space. It represents societal meanings and the natural chronicles of our ecosystems and environments. However, these records are often fundamentally flawed and misleading.

Ashby emphasizes the museum’s role, particularly in natural history, as an extensive catalog of past life on our planet. Its original purpose was to document everything from flora to fauna and enhance our understanding of the natural world.

Times have changed. As Ashby reveals in this captivating work, he critiques the shortcomings of museums, challenging our preconceived notions. Notably, much of our natural history remains hidden in poorly lit storage rather than publicly displayed.

Readers will soon discover the significance of the areas typically off-limits to the public. Ashby notes that there are approximately 70,000 flowering plant species worldwide that scientists have yet to fully describe.

The book delves into the preservation processes for animal skeletons, highlighting how flesh is removed for conservation, how insects are prepared for display, and how taxidermy is conducted. These behind-the-scenes insights are among the book’s most intriguing aspects. Ashby also points out the unrealistic representation of frogs due to shrinkage and features a segment on a renowned glassmaker recognized for creating lifelike floral reproductions.

Yet, the lack of representation extends beyond plants. Ashby highlights the biases in what we learned during school trips to such institutions. He cites a 2008 study indicating that merely 29% of mammal displays and 34% of bird exhibits in natural history museums feature females, resulting in a limited understanding of habitat contributions. This imbalance can be attributed to the more visually appealing male specimens and the fact that those who collect and exhibit are predominantly male and often white Westerners.

Ashby advocates for addressing the misrepresentation issue within museums, asserting that our education about nature is severely lacking due to the biases of past generations. Many male mammalian skeletons are misrepresented in museum displays due to curatorial choices that remove pelvic bones.

Though the book was published prior to the intentional dismantling of American scientific institutions, it reflects the prevailing anti-expert sentiment. This makes it all the more vital to read. We must reflect on what is excluded from museum exhibits as seriously as we do what is included.

As Ashby asserts, “The work that is being done at the Natural History Museum is more crucial than ever, and the role that must be played in order to safeguard the future of humanity is just beginning to unfold.”

Can Underground Natural Hydrogen Assist the UK in Achieving Net Zero?

The Lizard Peninsula in Cornwall has rocks capable of producing hydrogen gas

PIO3/SHUTTERSTOCK

Recent discoveries of small amounts of underground hydrogen gas have sparked a global search for a potential zero carbon fuel source, yet the UK has largely been overlooked by prospectors.

According to a Briefing from the Royal Society on natural hydrogen production, the lack of exploration is not due to geological factors. “There are rocks that could produce hydrogen, but no research has been conducted,” states Barbara Sherwood Lollar, who contributed to a report at the University of Toronto.

The UK also doesn’t lack interest in gas. The latest Hydrogen Strategy highlights its crucial role in achieving the ambition of becoming a clean energy superpower through low-carbon production methods for heavy industry and transportation, yet natural hydrogen is not mentioned as a potential source.

Novelty plays a role in this oversight, according to Philip Ball, who contributed to the report and invests in natural hydrogen firms at Keele University. “Essentially no one is paying attention. There’s no regulation for this emerging sector, and there’s a lack of understanding.”

However, the situation may be changing. Ball notes that several companies have obtained rights to explore hydrogen in parts of the UK, including Devon in the southwest, while multiple universities conduct related research. The UK Geological Survey is also delving into the country’s potential for natural hydrogen, drawing on a wealth of existing geological data.

There is reason to believe that natural hydrogen exists beneath the surface. A report by the Royal Society notes that certain types of rocks, particularly iron-rich super-solid rocks, can generate hydrogen when interacting with water. Such formations are found in locations like the Lizard Peninsula in Cornwall and Scotland’s Shetland Islands. Geoplasms in areas like the North Pennines could also yield hydrogen through the breakdown of water molecules via natural radioactivity.

“It will definitely be found in the UK,” Ball asserts. “The question remains whether it will be economically viable.”

If hydrogen is discovered in the UK, expectations should be tempered; Sherwood Lollar emphasizes that one of the report’s goals was to correct some exaggerated claims about natural hydrogen, such as the concept of massive quantities of gas continually rising from the Earth’s mantle and core.

Nonetheless, it is critical to consider conservative estimates of the hydrogen production within the Earth’s crust. The report indicates that around 1 million tonnes of hydrogen permeates the crust annually. “Even capturing a fraction of this could significantly contribute to the hydrogen economy,” Sherwood Lollar states.

Neck and Facial Massage: A Natural Way to Detoxify Your Brain

Magnetic resonance image scan of the human brain

Phanie/Sipa Press/Alamy

A device designed for facial and neck massage suggests it might enhance the brain’s waste removal system and alleviate symptoms associated with conditions like Alzheimer’s disease.

Cerebrospinal fluid (CSF) envelops the brain and inflates it before moving through a network of delicate tubes known as grinft blood vessels. Research on mice indicates that this fluid clears waste produced by brain cells, including proteins linked to diseases like Alzheimer’s and Parkinson’s, such as beta-amyloid.

This has prompted researchers to consider whether increasing CSF flow could promote brain health. However, they note that the grinft vessels, previously only discovered deep within the neck, are difficult to access. Gou Young Koh, from the Advanced Science and Technology Research Institute in Korea, remarks on this challenge.

Recently, Koh and his team identified a network of grinft vessels located just five millimeters beneath the skin on the faces and necks of mice and monkeys. They made this breakthrough by administering fluorescent dyes that label the CSF and imaging the subjects under anesthesia. “We utilized a different kind of anesthesia than was applied in earlier studies. The previous anesthetic blocked the visualization of vessels close to the skin,” Koh explains.

In their effort to determine if massaging these vessels could boost CSF flow, the researchers developed a device with small rods attached to a 1 cm cotton ball. They used it to gently stroke down the face and neck of a 2-year-old mouse for a few months, applying strokes for one minute on younger mice. “A gentle facial and neck massage can compress the liquid and enhance the CSF flow,” Koh states.

After 30 minutes of massage, CSF flow was observed to increase nearly threefold in the brains of the mice compared to their flow prior to the massage. Furthermore, this process seemed to reverse age-related decreases in CSF flow. “After stimulation, the CSF flow in older mice appeared comparable to that of younger mice [who hadn’t received the massage],” Koh elaborates.

In their unpublished findings, the team observed similar outcomes in monkeys. They also identified glymphetic blood vessels in human cadavers, implying that massage could stimulate CSF flow in humans, as suggested by Koh.

However, due to anatomical differences between mice, monkeys, and humans, further investigations are necessary to confirm this, remarks Vesa Kiviniemi from Uru University in Finland. “It’s a slightly different scenario.”

Moreover, it remains uncertain whether increased CSF flow can genuinely mitigate brain aging or offer protection against neurodegenerative conditions like Alzheimer’s. Stephen Prucks of the University of Bern in Switzerland stated that Koh’s team aims to investigate this with mice that exhibit Alzheimer-like traits.

The Truth About Endorphins and Runner’s High: How to Increase Your Natural High

For those who are not runners and don’t find the appeal of a two-hour run at 6am, it’s known that running (and other forms of aerobic exercise) can create powerful chemical sensations that are comparable to real drugs.

The body naturally produces two pleasurable substances associated with the runner’s high. Endorphins are well-known neurotransmitters that can be likened to morphine for their pain-relieving properties.

One theory suggests that our ancestors evolved to produce endorphins to help them chase prey or escape predators by numbing foot pain and blisters.

Research indicates that for runners, a long-term, moderately intense run is the ideal scenario for endorphin production. If you’re aiming to experience the runner’s high, try a “tempo” run.

After a good warm-up, aim to run for at least 20 minutes at a pace of about 6 or7 out of 10 (with 10 being an all-out sprint).

While endorphins have traditionally been credited with causing the euphoria of the runner’s high, recent research suggests that another substance may be the actual source of the uplift felt towards the end of a run.

Endocannabinoids are molecules similar to those in marijuana that enhance the mood, but are naturally produced by the body.

Research shows that when cannabinoid receptors are blocked in mice, they exhibit reduced activity. In a study in 2021, researchers at the University Medical Center Hamburg Eppendorf found that even when the opioid receptor that binds to endorphins is blocked, runners still experience the high.

This suggests that cannabinoids may be more responsible for the runner’s high than previously thought.

In the study, participants ran at a moderate pace for 45 minutes. To achieve a similar high, aim for a consistently challenging pace where holding a conversation becomes difficult.


This article addresses the question (posed by Emily Marine of Colchester) “When does the runner’s high kick in?”

Tax credit proposed to assist homeowners affected by natural climate-related disasters

On Tuesday, two U.S. senators introduced a bill with the goal of reducing damage to homes and communities caused by floods, wildfires, and other natural disasters by offering federal tax credits.

The bill, proposed by D-Calif. and R-Mont. lawmakers Adam Schiff and Tim Sheehy, aims to provide tax credits to incentivize people to upgrade their homes with improved protections against major disasters like hurricanes and wildfires.

The bipartisan legislation, known as the Increased Resilience, Environmental Weathering, and Enhanced Firewall Act, seeks to enhance community resilience in the face of increasing climate change impacts such as more frequent and severe floods, hurricanes, and other disasters across the nation.

Speaking to NBC News, Schiff explained that the proposed law was inspired by the devastating fires in Southern California and aims to address the growing insurance crisis in disaster-prone areas where insurance companies are pulling out of the market.

The bill proposes a federal tax credit that covers 50% of the cost of home resilience upgrades, including measures like underground sealed walls, automatic shutoff valves for water and gas lines, and fireproof roofing materials.

To qualify for the tax credits, states must have experienced a federally declared natural disaster within the past ten years, ensuring that the bill not only benefits recent disaster victims but also helps all Americans mitigate risks from hurricanes, floods, tornadoes, and wildfires.

Sheehy, who collaborated with Schiff on the legislation, emphasized that the bill aims to lower financial barriers for individuals seeking to protect themselves from extreme weather events and their property.

The tax credits are capped at $25,000 for families earning under $200,000 annually, with a phased-out limit for higher-income households. Families earning less than $300,000 could receive up to $12,500 in credits.

According to Schiff, the tax credits will be fully refundable and adjusted for inflation starting in 2026.

Schiff highlighted the importance of targeting relief to those most in need and aiming to reduce costs in disaster-prone regions by incentivizing resilient building practices through tax credits.

The use of natural fibers in wet wipes can have damaging effects on soil and wildlife

Fibers from wet wipes can get mixed into fertilizer if flushed down the toilet.

Linda Kennedy/Alamy

The natural fibers increasingly used in wet wipes can actually have a more negative impact on the environment than the synthetic fibers they are designed to replace.

Viscose and lyocell, made from wood cellulose, are often used in wet wipes and clothing as an alternative to fibers such as polyester, which are primarily byproducts of fossil fuels.

“These are in high street stores, so you can get them in the ethically conscious consumer sections of fast fashion stores,” he says. winnie courten jones At Bangor University, UK.

However, there is uncertainty as to whether they are truly better than alternative materials. “There's been a bit of a knee-jerk reaction to move away from traditional fossil fuel-based plastics and replace them with alternatives, and there hasn't been much testing of those other materials,” Corton says. Jones says.

To learn more, she and her colleagues tested the effects of viscose, lyocell, and polyester on the soil and some of the animals that live there. Wet wipes often end up in sewage treatment plants along with microfibers that fall off clothes in washing machines. These are accidentally spread into the soil through sludge from these plants, which is used as fertilizer.

The research team is a type of earthworm (Eisenia fetida) changes the concentration of viscose, lyocell, and polyester in the soil. Approximately 30 percent of people exposed to high concentrations of polyester died after 72 hours. In contrast, almost 60 percent of those exposed to lyocell and 80 percent of those exposed to viscose died.

When researchers tested it at lower concentrations that are more commonly encountered in the real world, they found that worms exposed to viscose or lyocell reproduced less than worms exposed to polyester. Ta. It is unclear why this occurs, but fibrous material, regardless of its composition, can be toxic to earthworms.

But it's important to know that the message is not that if they go into the environment it will be better.”

Researchers uncover natural graphene flakes in lunar soil samples

Planetary scientists have identified layers of graphene formed alongside complex minerals in lunar regolith samples collected by China's Chang'e-5 probe, a discovery that provides new insight into the origins of the Moon and supports the hypothesis that it contains carbon.

Structural and compositional characteristics of few-layer graphene in lunar soil samples from Chang'e-5. Image courtesy of Zhang others., doi: 10.1093/nsr/nwae211.

“Graphene's novel physical phenomena and extraordinary properties have revolutionized research in condensed matter physics and materials science,” said Professor Zhang Wei of Jilin University and his colleagues.

“It plays an increasingly important role in a wide range of fields, including planetary and space sciences.”

“It is estimated that about 1.9% of all interstellar carbon exists in the form of graphene, and protosolar graphene has been identified in carbonaceous chondrite meteorites.”

The researchers analyzed an olive-shaped lunar soil sample measuring about 2.9 millimeters by 1.6 millimeters, collected by the Chang'e-5 mission in 2020.

Using a specialised spectrometer, they discovered iron compounds in the carbon-rich parts of the sample that are closely related to the formation of graphene.

The researchers then used advanced microscopy and mapping techniques to determine that the carbon content within their samples was made up of “flakes” of two to seven layers of graphene.

The scientists propose that few layers of graphene could have formed during volcanic activity in the Moon's early existence, catalysed by solar wind stirring up the lunar soil and iron-containing minerals, prompting a change in the structure of carbon atoms.

Meteorite impacts creating high temperature and pressure environments may also have led to the formation of graphene.

“The first study to confirm the presence of native few-layer graphene in lunar soil samples by examining its microstructure and composition,” the authors said.

“Our discovery provides new insight into the origin of the Moon and supports the hypothesis that the Moon contains carbon.”

“Moreover, graphene's unusual properties depend strongly on its structure and environment.”

“Further investigation of the properties of natural graphene could provide more information about the geological evolution of the Moon.”

“Consequently, the formation of natural graphene by mineral catalysis sheds light on the development of low-cost, scalable synthesis techniques for high-quality graphene.”

“This will therefore propel a new lunar exploration program forward, with some exciting breakthroughs in the future.”

In contrast, other hardwoods showed mixed efficacy, and oak showed effectiveness against enteroviruses. Image courtesy of Schroff. others., doi: 10.1021/acsami.4c02156.

Since ancient times, wood has played a vital role in tools, utilities, and construction.

The 20th century witnessed a depletion of wood resources, prompting the emergence of alternatives like plastics and metals for interior surfaces and fixtures.

A growing concern for sustainability and the unique qualities of wood has led to a resurgence in its use across various applications.

The 21st century has brought new health challenges, including viral outbreaks like SARS and COVID-19, emphasizing the importance of surface hygiene.

Viruses can persist on surfaces as fomites, with enveloped viruses having shorter survival times compared to non-enveloped viruses.

Wood has been known for its antibacterial and antifungal properties, but its antiviral capabilities were not thoroughly explored until this study.

Researchers investigated how different types of wood affect the infectivity of enveloped and non-enveloped viruses.

The study found that certain types of wood could significantly reduce viral infectivity within hours, showcasing their potential as natural antiviral materials.

Their research paper was published in the journal ACS Applied Materials & Interfaces.

Sea buckthorn is a deciduous, spiny plant that grows along the coasts of northwestern Europe and in temperate regions of central Asia.

Its fruits and leaves are widely used Sea buckthorn oil has nutritional, medicinal, and functional properties and is rich in omega-3 and omega-6 fatty acids, vitamins E, B, A, and polyphenols.

The plant was introduced in Canada in the early 2000s following research into the crop's commercial potential by government agencies.

“Sea buckthorn is a unique crop with great potential for use,” said Dr. Renan Danielski. student at the University of Newfoundland.

“Popular in Asia and northwestern Europe, there is an opportunity to replicate this success in North America by leveraging the unique qualities of locally grown varieties.”

Danielski and Professor Fereydoun Shahidi of Memorial University of Newfoundland were motivated by the experimental status and limited commercialization of sea buckthorn in North America to date, and research on the antioxidant properties of Canadian cultivars. We set out to characterize the unique composition of polyphenols, a type of chemical compound.

“Understanding how our varieties compare globally will help us communicate our benefits to consumers and establish our presence in the market,” Professor Shahidi said.

The findings highlight the presence of key polyphenolic compounds in sea buckthorn pomace and seeds, each boasting potential health benefits ranging from cardiovascular protection to anti-inflammatory properties. .

Importantly, geographic factors influence the polyphenol profile of sea buckthorn berries, and researchers found that several different compounds with enhanced bioactivity are present only in sea buckthorn varieties grown in Newfoundland. is that we have identified.

Additionally, sea buckthorn extract has demonstrated promise in vitro It has anti-diabetic and anti-obesity potential, paving the way for further research into its mechanisms and potential therapeutic applications.

“This is a first step toward understanding how sea buckthorn polyphenols can modulate our physiology in beneficial ways,” Danielski said.

“Future research should focus on understanding the mechanisms behind those effects and further experiments using animal models and humans.”

“If these effects are confirmed, in vivoWe can imagine using sea buckthorn polyphenols for therapeutic and pharmacological purposes to help prevent and treat diabetes, obesity, and many other conditions. ”

Physicists discover first natural unconventional superconductor

Solid state chemistry has led to the creation of numerous materials with unique properties not found in nature. For instance, the high-temperature superconductivity of copper oxide compounds known as cuprates is so distinct from the superconductivity of naturally occurring metals and alloys that it is often referred to as “unconventional.” Unconventional superconductivity is also present in other synthetic compounds like iron-based superconductors and heavy fermion superconductors. Physicists at Ames National Laboratory have uncovered strong evidence of unconventional superconductivity in synthetic samples of Rh17S15, a mineral that exists in nature as miassite.



Miasite is one of only four minerals found in nature that act as a superconductor when grown in the laboratory, and is the only mineral ever known to exhibit unconventional superconductivity in its clean synthetic form. It is the only mineral that exists. Image credit: Paul Canfield.

Superconductivity is the ability of a material to conduct electricity without any loss of energy.

Superconductors have various applications including medical MRI machines, power cables, and quantum computers.

Conventional superconductors are well understood but have low critical temperatures.

The critical temperature is the highest temperature at which a material displays superconductivity.

In the 1980s, scientists discovered unconventional superconductors with significantly higher critical temperatures, all of which were manufactured in a lab, challenging the notion that unconventional superconductivity is not a natural occurrence, as stated by Ruslan Prozorov, a researcher at Ames National Laboratory.

“Miasite is a fascinating mineral due to its intricate chemical composition,” he added.

Continued efforts to grow miasite crystals as part of a broader exploration into compounds combining elements with high melting points and volatile elements have led to the discovery of unconventional superconductors in the Rh-S system.

Professor Paul Canfield highlighted the unique process of growing crystals at low temperatures with minimal vapor pressure in elements like Rh, contrary to pure elements found in nature.

Further tests confirmed that miasite functions as an unconventional superconductor, enhancing the understanding of superconductors.

Keeping your eyes open can lead to faster sleep because of the body’s natural response to darkness.

Do you find yourself tossing and turning all night once again? Are you counting down the hours until your unyielding alarm goes off? If you’re a reader struggling with sleep, you’re not alone.

Many of us have experienced the frustration of feeling like the more we try to force ourselves to sleep, the more it eludes us. But is this truly the case?

According to recent trends on TikTok, trying to fall asleep can actually hinder your ability to do so. In fact, influencers are actively promoting the idea of not trying to fall asleep. This counterintuitive technique is known as “paradoxical intent,” and while it may be new to TikTok, it’s a scientifically backed method.

As it turns out, there is scientific support behind TikTok after all. Who would have thought?

“Paradoxical intentions are a well-established therapeutic technique that has been used in psychotherapy for decades,” explains Colin Espie, Professor of Sleep Medicine at the Nuffield Department of Clinical Neuroscience, University of Oxford. “In fact, I conducted my first research using paradoxical intention therapy in the 1980s.”

Read more:

What is paradoxical intent?

Paradoxical intent can be useful for various phobias and anxiety disorders, but the underlying premise remains the same: deliberately adopting an attitude contrary to the desired outcome.

For instance, if a patient has a phobia of failure, a psychologist might assist the patient in confronting failure instead of avoiding it, ultimately reducing fear and anxiety.

“The fundamental directive regarding sleep is that you should aim to stay awake when you’re in bed, feeling sleepy, or waking up in the middle of the night,” Espie explains. “You need to switch your intention from sleeping to staying awake.”

Although this approach may seem illogical at first, it is based on the idea that trying too hard to sleep can backfire.

“Sleep is largely an involuntary process, so attempting to control it often interferes with the natural sleep process,” Espie says. “Essentially, you can’t force sleep; you can only invite it. It’s like stepping back from being awake rather than actively pursuing sleep.”


How to use paradoxical intention to fall asleep faster

Implementing paradoxical intent is simple, but there are some considerations to keep in mind before giving it a try.

1. Go to bed when you feel sleepy (not before)

It may seem obvious, but you can’t sleep unless you’re tired. While paradoxical intention involves trying to stay awake, attempting this during the day is not as challenging.

“Sometimes people go to bed early because they’re desperate for sleep, but if they’re not morning people, they may struggle, leading to falling asleep early in the evening,” Espie notes.

2. Prepare for bed as usual

Despite its fancy name, paradoxical intent doesn’t require any elaborate setup. There’s no need for high-tech gadgets or sleep meditation apps; simplicity is key.

Espy recommends getting into bed, turning off the lights, and lying down.

3. Keep your eyes open instead of closing them

There are several ways to practice paradoxical intent, but this is the simplest approach.

“Keep your eyes open, assume that position, and tell yourself, ‘I am not falling asleep, I am not falling asleep, I am not falling asleep,'” Espie suggests.

“Then, encourage yourself further by saying phrases like, ‘I will stay awake a bit longer,’ or ‘I will keep my eyes open for 10 more seconds.’ Whenever you feel your eyes drooping, say ‘No.'” he explains.

Gradually, it becomes increasingly challenging to keep your eyes open, and instead of struggling to fall asleep, you find yourself struggling to keep your eyes open.

If you sense sleep approaching, try not to resist or acknowledge it too much. Simply allow it to happen.

As an additional tip, Espie recommends keeping a tissue or handkerchief under your pillow in case your eyes start to water.

Read more:

4. Don’t take it too literally

The most common mistake people make when employing paradoxical intent is interpreting it too literally.

“It’s not about tormenting yourself to stay awake at all costs. The goal isn’t to prevent yourself from sleeping,” Espie clarifies.

“If you overdo it, you will be overly determined to stay awake, interfering with sleep. The real aim is to allow sleep to naturally happen,” he adds.

5. Be consistent

Changing your sleep patterns doesn’t happen overnight, so persistence is key. “To derive the most benefit from these strategies, you need to continue using them for a while,” Espie advises.

“One challenge with such an approach,” notes the Oxford professor who advocates for it, “is that if it works initially but falters over time, people may become disillusioned, potentially leading to depression.”

“This is usually because individuals underestimate the extent of their sleep problems and the ingrained habit of overthinking,” he explains.

If the issue persists, seeking professional help is crucial. “It’s not just a lifestyle matter,” Espie emphasizes, “sometimes, people need assistance.”

“This is not a hack”

Contrary to what TikTokers may suggest, there is no magical trick to manipulate our brains.

“You can’t outsmart human nature,” Espie asserts. “Sleep is an essential process, and this is not a technique to switch on sleep. It’s not a game.”

He finds it intriguing that sleep advice and techniques are gaining popularity on social media. TikTok’s #insomnia tag currently boasts around 600,000 posts, while the #sleep tag has over 2.9 million posts.

Meanwhile, according to a study investigating American adults, nearly three-quarters of social media usage occurs right before bedtime. It might be an opportune time to learn new sleep strategies, don’t you think?

According to Espie, the increasing online interest in the subject could indicate rising levels of insomnia.

“The value of sleep and the need for effective solutions to sleep issues are sorely underestimated, with many young individuals in particular struggling,” he observes.

“This is why paradoxical intentions are so beneficial; they remind us that the answer isn’t a gimmick, pill, or potion. It’s sleep itself.

“The solution lies in establishing healthy sleep habits to attain the rest you deserve.”

Albanian mines reveal large reserves of natural hydrogen gas underground

Albanian mine where hydrogen naturally seeps through rocks

FV.Donze

The largest flow of natural hydrogen gas ever recorded has been measured deep in an Albanian mine. The discovery could help locate underground reserves of this clean fuel.

“The lather is really intense,” he says. Laurent Truche Researchers at France’s Grenoble-Alpes University measured gas in a pool of water about a kilometer underground. “It’s like a jacuzzi.”

Companies are currently searching for natural hydrogen deposits around the world as a source of clean fuel, but there is scant evidence that this “golden hydrogen” has accumulated in large quantities. Most claims about vast subsurface hydrogen deposits rely on extrapolation rather than direct measurements.

In search of more substantive evidence, Truche and his colleagues descended on Albania’s Balkizekromite mine. There, hydrogen gas escaping from the rocks has caused several explosions. The mine is also located in an outcrop of iron-rich rocks known as ophiolites. In other places, such as Oman, water is known to react with such rocks to produce hydrogen.

The researchers found that more than 80% of the gas bubbling out of the pool was hydrogen, mixed with methane and small amounts of nitrogen. That gas was flowing at a rate of 11 tons per year, almost an order of magnitude more than any other gas. Flow of hydrogen gas measured from a single point source elsewhere on the Earth’s surface.

To determine the source of the gas, the researchers also modeled various geological scenarios that could produce such flows. They found that the most likely scenario is that the gas is coming from a deeper reservoir of hydrogen accumulated in faults beneath the mine. Based on the geometry of the fault, they estimate that the reservoir contains at least 5,000 to 50,000 tons of hydrogen.

“This is one of the largest amounts of natural hydrogen ever measured,” he says. Eric Gaucher an independent geochemist focused on natural hydrogen.

But he says it’s still not a huge amount. Jeffrey Ellis At the U.S. Geological Survey. But evidence of stable hydrogen accumulation supports the idea that there is more hydrogen stored underground, he says. “We need to look deeper.”

Incredible flow of natural gas beneath permafrost

Scientists have discovered that methane trapped beneath Svalbard’s permafrost could escape and put it at risk of a warming cycle. Frequent methane accumulations found in well exploration highlight the potential for increased global warming as permafrost thaws. Credit: SciTechDaily.com

Scientists say large amounts of methane may be trapped beneath the permafrost and could escape if it thaws.

Research in Svalbard has shown that methane is moving beneath the permafrost. Lowland regions have ice-rich permafrost, which acts as an effective gas seal, while highland regions with less ice appear to be more permeable. If permafrost thaws too much, greenhouse gas emissions could leak and temperatures could rise further.

Millions of cubic meters of methane are trapped beneath Svalbard’s permafrost. And scientists now know that methane can escape by moving beneath the cold seal of permafrost. A large-scale escape could create a warming cycle that would cause methane emissions to skyrocket. Global warming will thaw permafrost, releasing more gases; warming will thaw more permafrost, releasing more gases. These mobile methane deposits may exist elsewhere in the Arctic, as Svalbard’s geological and glacial history is very similar to other parts of the Arctic region.

“Methane is a powerful greenhouse gas,” said the study’s lead author, Dr. Thomas Birshall of the Svalbard University Center. Frontiers of Earth Science. “Although leakage from beneath the permafrost is currently very low, factors such as retreating glaciers and thawing of the permafrost could ‘uncover’ the problem in the future.”

Refrigerated

Permafrost, ground that remains below freezing Celsius It has been prevalent in Svalbard for over two years. However, it is not uniform or continuous. The western part of Svalbard is warmer due to ocean currents, so the permafrost can be thinner and more patchy. Permafrost in highlands is drier and more permeable, whereas permafrost in lowlands is saturated with ice. The rocks below are often a source of fossil fuels and emit methane, which is locked away by permafrost. However, even where permafrost exists continuously, gas can escape depending on the geographical features.

The bottom of permafrost is difficult to study because it is inaccessible. But over the years, many wells have been sunk into permafrost by companies looking for fossil fuels. Researchers used historical data from commercial and research wells to map permafrost across Svalbard and identify permafrost gas accumulations.

“My boss, Kim, and I looked at a lot of historical well data in Svalbard,” Birchall said. “Kim noticed one recurring theme, and that was the accumulation of gas at the bottom of the permafrost.”

Discover methane accumulation

Initial temperature measurements are often compromised by heating the drilling mud to prevent freezing of the wellbore. But by observing trends in temperature measurements and monitoring boreholes over time, scientists were able to identify permafrost. They also looked at ice formation within the wellbore, changes in drill chips produced during drilling of the wellbore, and changes in background gas measurements.

Well monitors confirmed the flow of gas into the wellbore, indicating that gas was accumulating beneath the permafrost, and abnormal pressure measurements indicated that the icy permafrost was acting as a seal. I did. In other cases, the permafrost and underlying geology are suitable for trapping gas, and even if the rock is a known source of hydrocarbons, it may not be present and the gas produced This suggests that they were already on the move.

Unexpectedly frequent discoveries

Scientists stressed that gas buildup is much more common than expected. Of his 18 hydrocarbon exploration wells drilled in Svalbard, eight showed evidence of permafrost, and half of them showed gas accumulation.

“All wells that encounter gas accumulation have done so by chance. In contrast, hydrocarbon exploration wells that specifically target accumulation in more typical environments have a success rate of well over 50%. It was below,” Birchall said. “This seems to be a common occurrence. One anecdotal example comes from a recently drilled well near the airport in Longyearbyen.Drillers heard bubbling coming from the well. So I decided to take a look, equipped with a rudimentary alarm designed to detect explosive levels of methane. As soon as I held the alarm over the well, it went off.”

Impact on climate change

Experts have shown that the active layer of permafrost – the top 1-2 meters that thaws and refreezes seasonally – is expanding as the climate warms. However, little, if any, is known about how deeper permafrost is changing. Understanding this depends on understanding fluid flow beneath permafrost. As permanently frozen permafrost becomes thinner and more splotchy, this methane can move and escape more easily, accelerating global warming and potentially exacerbating the climate crisis.

Can Natural Genetic Factors Lead to Having More Children in a Shorter Time?

Scientific Evidence Backs Antagonistic Pleiotropy Theory of Aging

Comprehensive studies have confirmed the antagonistic pleiotropy theory of aging, indicating a genetic correlation between high fertility and shortened lifespan. Nonetheless, environmental factors are highlighted as major influencers of modern human lifespan and reproductive behavior.

New research further supports the idea that genes promoting early reproduction can accelerate aging but emphasizes the overriding role of environmental factors in determining longevity and reproduction.

Originating in a 1957 theory proposed by evolutionary biologist George Williams, the antagonistic pleiotropy theory posits that genetic mutations favoring early reproduction could simultaneously contribute to aging, making life shorter.

The theory was tested in a new study led by the University of Michigan, involving over 276,000 individuals, reaffirming its validity. The researchers found distinct genome-wide evidence supporting the theory.

A novel breakthrough discovery showcased a strong negative genetic correlation between reproduction and longevity, suggesting that mutations promoting reproduction tend to shorten lifespan. However, this link is also influenced by environmental factors.

It was established that the number and timing of reproduction can impact lifespan. Remarkably, having two children was linked to the longest lifespan, according to this study, reinforcing previous research findings.

The concept of pleiotropy suggests that a single mutation can impact multiple traits, while antagonistic pleiotropy posits that mutations can be beneficial or harmful depending on various circumstances. The evolutionary basis of aging is seen through this lens.

In line with this, the study’s outcome points to significant environmental changes, such as lifestyle and technological advances, as opposed to genetic variants identified as drivers of human phenotypic changes.

Researchers find natural method to enhance the meat-like qualities of plant-based meat

Recent research has revealed that fermenting alliums such as onions with fungi can naturally mimic the flavor of meat, offering a promising solution for enhancing plant-based meat substitutes without the use of synthetic additives. measures are provided.

Plant-based alternatives like tempeh and bean burgers offer protein-rich options for those looking to cut back on meat. However, it is difficult to imitate the taste and aroma of meat, and many companies use artificial additives for this purpose. Recent research in ACS Journal of Agricultural and Food Chemistry revealed a promising solution. Onions, chives, and leeks can produce natural compounds that resemble meat flavors when fermented with typical fungi.

An innovative approach to natural meat flavoring

When food manufacturers want their plant-based meat alternatives to taste more like meat, they often add precursor ingredients found in the meat that transform into flavorants during cooking. Alternatively, flavors are first prepared by heating flavor precursors or other chemical manipulations and then added to the product.

Because these flavors are created through a synthetic process, many countries do not allow food manufacturers to label them as “natural.” To utilize plant-based “natural” meat flavors, flavor chemicals must be physically extracted from plants or produced biochemically using enzymes, bacteria, and fungi. So YanYan Zhang and colleagues wanted to see if they could produce the same chemicals from vegetables and spices using fungi, which are known for producing meat-like tastes and smells from synthetic ingredients.

Allium releases the aroma of meat

The team fermented different fungi seed After experimenting with different foods, I found that meaty aromas only come from foods in the allium family, such as onions and leeks. The sample with the strongest aroma was one in which the fungus Polyporus umbellatus was used to ferment onions for 18 hours, producing a fatty and meaty aroma similar to liverwurst.

The researchers used gas chromatography-mass spectrometry to analyze onion ferments to identify flavor and odor chemicals, many of which are known to be responsible for various flavors in meat. discovered a chemical substance. One of the chemicals they identified was bis(2-methyl-3-furyl) disulfide, a strong odorant found in meat and savory foods.

The researchers say the high sulfur content of alliums contributes to their ability to produce meat-flavoring compounds, and these compounds often also contain sulfur. These onion ferments could one day be used as a natural flavoring agent in a variety of plant-based meat substitutes, the researchers say.
