One Magnet Doubles Plant Growth — Why Is This Physics "Ignored"?

 Forbidden Roots,  28 Dec 2025

In 1974, two independent researchers documented plant growth results that challenged modern agriculture.

 Radishes reached nearly three times their normal size and cucumbers ripened weeks early using no fertilizer, no special soil, and only a carefully placed magnet. The findings were dismissed as impossible and then quietly forgotten. 

This video explores the lost science of magnetoculture, examining the work of Albert Roy Davis, Walter Rawls, and later researchers who identified measurable links between magnetic fields, paramagnetic soils, and plant growth. Using original photographs, historical records, and peer-reviewed studies, we examine evidence showing faster germination, improved water absorption, and yield increases of 10–25% under controlled conditions without additional chemical inputs.

 Finally, the video asks why physics-based agriculture faded as chemical fertilizer use surged, and what that shift reveals about incentives, economics, and forgotten alternatives. This video does not ask for belief — it asks for observation, replication, and critical thought.

 Earth’s pulse is still free.

Scientists Are Turning Food Waste Into Farming Gold and Health Breakthroughs

BY AMERICAN CHEMICAL SOCIETY, DEC. 30, 2025

From farm leftovers to leafy greens tossed aside, food waste is proving far more valuable than expected. Scientists are finding ways to turn scraps into tools for sustainable farming, gut health, and bioactive ingredients.

What we throw away as food waste may hold the key to healthier crops, stronger ecosystems, and new medical compounds.

Food waste is often seen as little more than compost material, but new research shows it can offer much more. Scientists are discovering valuable uses for discarded food, ranging from dried beet pulp to coconut fibers broken down by millipedes. Four recently published studies in ACS journals describe how food waste can support more sustainable farming practices and provide new bioactive compounds for pharmaceutical use.

Turning Agricultural Waste Into Crop Protection

Researchers writing in ACS’ Journal of Agricultural and Food Chemistry report that sugar beet pulp could help lower agriculture’s dependence on synthetic pesticides. After sugar is extracted, this pulp remains and accounts for roughly 80% of the beet’s original weight. In laboratory tests, scientists converted the pectin-rich pulp into carbohydrates that stimulated plants’ own defense systems. These natural responses helped protect wheat from diseases such as powdery mildew.

Sustainable Alternatives for Seedling Growth

Coconut fibers processed by millipedes may offer a greener substitute for peat moss, which is commonly used to start seedlings but harvested from environmentally sensitive areas that help protect groundwater quality. A study published in ACS Omega evaluated this coconut “millicompost” as a peat alternative. When blended with other plant materials, the compost supported bell pepper seedling growth just as effectively as traditional peat-based growing media.

Overlooked Greens With Digestive Benefits

A review in ACS’ Journal of Agricultural and Food Chemistry suggests that radish tops, which are often thrown away, may be even more nutritious than the root itself. These peppery greens contain high levels of dietary fiber and bioactive compounds. In several laboratory and animal studies, components such as polysaccharides and antioxidants encouraged the growth of beneficial gut microbes, indicating they may also support overall digestive health in humans.

Preserving Bioactive Compounds for Industry

Research described in ACS Engineering Au outlines a way to stabilize beneficial compounds extracted from beet leaves so they can be used in cosmetics, pharmaceuticals and food products. Scientists aerosolized and dried a liquid mixture containing antioxidant-rich beet-green extract and an edible biopolymer. This process produced microparticles that encapsulated the extract. According to the researchers, these microparticles showed higher antioxidant activity than the extract alone, suggesting the coating helps protect the compounds from degradation.

Ancient Climate Shift Linked to the Mysterious Extinction of the Real-Life “Hobbit” Humans

BY U. OF WOLLONGONG, DEC. 30, 2025

https://scitechdaily.com/ancient-climate-shift-linked-to-the-mysterious-extinction-of-the-real-life-hobbit-humans/

Homo floresiensis is an extinct species of early human that lived on the Indonesian island of Flores during the Late Pleistocene.

A new study links climate stress to the disappearance of the early human species Homo floresiensis, known as the “hobbits” of Flores.

An international group of researchers, including scientists from the University of Wollongong (UOW), has uncovered strong evidence linking climate change to the disappearance of the early human species Homo floresiensis, commonly called the “hobbits.” Their findings, published in Communications Earth & Environment, suggest that this small-bodied human species left Liang Bua, a cave they had lived in for roughly 140,000 years, during a prolonged period of drought that persisted for thousands of years.

To reach their conclusions, the researchers analyzed chemical signals preserved in cave stalagmites alongside isotopic evidence from fossilized teeth of a pygmy elephant species (Stegodon florensis insularis) that formed a key part of the hobbits’ diet. These data point to a long-term shift toward drier conditions starting about 76,000 years ago.

The drying intensified into severe drought between roughly 61,000 and 55,000 years ago, closely matching the period when Homo floresiensis vanished from the area. Ongoing water shortages and growing competition for limited resources likely forced the hobbits to leave Liang Bua and may have contributed to their eventual extinction.

The discovery builds on decades of groundbreaking UOW research into Homo floresiensis, first discovered in 2003 in Liang Bua on the Indonesian island of Flores. Dubbed the hobbit due to its tiny stature, Homo floresiensis challenged prevailing theories of human evolution. It disappears from the fossil record around 50,000 years ago, but its fate has remained an enigma.
A Vanishing Food Source

The scientists used stalagmites, a natural archive of rainfall, to reconstruct past climate and rainfall. Analysis of oxygen-isotopes in fossil tooth enamel showed the pygmy elephants relied on river water, which became increasingly scarce. The pygmy elephant population fell steeply around 61,000 years ago, meaning that an important food source for the hobbits was disappearing.

“Surface freshwater, Stegodon and Homo floresiensis all decline at the same time, showing the compounding effects of ecological stress,” UOW Honorary Fellow Dr Gert van den Berg said. “Competition for dwindling water and food probably forced the hobbits to abandon Liang Bua.”

While Homo floresiensis fossils predate the earliest evidence of modern humans on Flores, Homo sapiens were traversing the Indonesian archipelago around the time the hobbits disappeared.

“It’s possible that as the hobbits moved in search of water and prey, they encountered modern humans,” Dr Gagan said. “In that sense, climate change may have set the stage for their final disappearance.”

Not All Microbes Are Bad: Scientists Reveal the “Invisible Friends” That Keep Us Healthy

Microbes are usually associated with disease, but new research from Flinders University highlights their lesser-known role in supporting health and resilience. By cataloguing microbes and natural compounds linked to positive health outcomes, researchers are challenging the long-standing pathogen-focused view of the microbial world. Credit: Shutterstock

Experts build database of “salutogenic potential” revealing how hidden microbes and natural compounds help keep us healthy.

Viruses and bacteria are often viewed as harmful, but researchers at Flinders University are drawing attention to the overlooked ways microbes can support and enhance human health.

In a newly published article in Microbial Biotechnology, Flinders microbial ecologist Dr. Jake Robinson and his colleagues highlight these so-called “invisible friends,” encouraging a shift away from seeing microbes and biogenic compounds only as dangers. Instead, their work emphasizes the value of understanding how many microorganisms play beneficial roles.

The researchers also introduce the ‘Database of Salutogenic Potential’, a first-of-its-kind open-access prototype that brings together evidence on microbes and natural compounds associated with positive health outcomes.

Rethinking Microbes and Health

“Emerging evidence shows that exposure to diverse environmental microbiomes and natural biochemical products also promotes health and resilience,” says Dr. Robinson.

“Rather than viewing biodiversity as something to be eliminated, contemporary approaches recognise the vital role of diverse ecosystems in creating salutogenic, or health-promoting, environments. By consolidating this data, we aim to rebalance the story of microbes – highlighting not only what makes us sick, but also what keeps us well. After all, health is not merely the absence of disease.”

Dr. Jake Robinson, from the College of Science and Engineering at Flinders University.

The researchers argue that this shift in perspective has implications well beyond medicine.

“The implications are far-reaching – from designing healthier cities and schoolyards to guiding ecosystem restoration and rethinking green infrastructure,” says Dr. Robinson.

The Overlooked Role of Salutogenic Microbes

Salutogenic microbes – those that promote health – and beneficial biochemical compounds have received comparatively little attention despite their important roles in regulating immune function and metabolic processes, suppressing disease, mitigating stress, and supporting ecosystem resilience.

“For well over a century, microbes and chemicals in the air have mainly been studied as threats – causes of infection, disease, and contamination. While this pathogen-centric lens has saved countless lives, it also risks overlooking the invisible biodiversity that actively supports human and planetary health,” says Dr. Robinson.

“Just as biodiversity loss threatens our health, restoring microbial and biochemical richness could be a key to healthier futures.”

Flinders University researchers and collaborators prepared a novel global open-access database cataloguing health-promoting microbes and biogenic compounds.

Building a New Evidence Base

The researchers have identified 124 potentially salutogenic microbial taxa and 14 biochemical compounds (from soil bacteria to plant-derived phytoncides) associated with benefits ranging from immune regulation to stress reduction.

“We aim to shift the balance between pathogen-centric and salutogenic perspectives, potentially enabling future applications in public health, urban planning, and ecosystem restoration,” says Dr. Robinson.

“While the current iteration of the database primarily centers on human health outcomes, it is designed to expand into ecosystem health domains, embedding salutogenic thinking into One Health frameworks.”

A Foundation for Future Research

The team emphasizes that the database is only the beginning.

“We’re not viewing this database as a finished tool. It’s a foundation – an invitation for scientists, practitioners, and communities to co-create a fuller picture of how invisible biodiversity sustains our lives,” says Dr. Robinson.

He continues, “However, even in its early form, this resource rebalances the traditional pathogen focus by consolidating data on salutogenic taxa, their benefits and environmental origins – and it will advance holistic approaches to environmental and human health.”

Dr. Robinson also has recently joined researchers in China to reveal that urban soils harbor more pathogens than forest, with a several-fold increase in the pathogen Klebsiella pneumoniae. The study in Communications Earth and Environment (Nature Springer) highlights the need to understand the risk to human health and soil biodiversity of bacterial zoonotic pathogens buildup in densely populated cities around the world.

Too Much Night Light? It Could Be Hurting Your Heart

BY AMERICAN HEART ASSOCIATION, DEC. 29, 2025

https://scitechdaily.com/too-much-night-light-it-could-be-hurting-your-heart/

Nighttime light pollution may quietly stress the brain, inflame the arteries, and put your heart in danger.

Exposure to artificial light at night appears to trigger stress in the brain and inflammation in the arteries, raising heart disease risk. Researchers say even modest light increases could have long-term cardiovascular consequences.

Higher exposure to artificial light at night was associated with increased stress activity in the brain, inflammation in the arteries, and a greater risk of heart disease, according to a preliminary study presented recently at the American Heart Association’s Scientific Sessions 2025.

Why Artificial Light at Night Matters

Artificial light at night, often referred to as nighttime light pollution, is nearly unavoidable in modern urban environments, the researchers noted. In this first-of-its-kind investigation, scientists combined brain imaging with satellite data to identify a biological pathway that may connect nighttime light exposure to heart disease.

“We know that environmental factors, such as air and noise pollution, can lead to heart disease by affecting our nerves and blood vessels through stress. Light pollution is very common; however, we don’t know much about how it affects the heart,” said study senior author Shady Abohashem, M.D., M.P.H., head of cardiac PET/CT imaging trials at Massachusetts General Hospital and an instructor at Harvard Medical School in Boston.

How Researchers Measured Brain Stress and Artery Inflammation

All participants underwent the same Positron Emission Tomography/Computed Tomography (PET/CT) scan. The study included 450 adults who had no history of heart disease and no active cancer. “This is a routine imaging test at my hospital,” Abohashem said. “The CT portion provides detailed anatomy, while the PET portion reveals metabolic activity in tissues. Using both imaging techniques together allows for the measurement of brain stress activity and arterial inflammation in a single scan.”

Key Findings From the Analysis

The results showed that people exposed to higher levels of artificial light at night had increased stress-related activity in the brain, more inflammation in blood vessels, and a higher likelihood of major cardiovascular events. Researchers gathered this information from medical records, which were independently reviewed by two blinded cardiologists who did not know any details that could influence their evaluations.

Risk rose steadily with increasing light exposure. Each standard deviation increase in nighttime light was linked to roughly a 35% higher risk of heart disease over five years and a 22% higher risk over ten years. These relationships remained even after accounting for traditional heart disease risk factors and other social and environmental influences such as noise pollution and socioeconomic status.

The association was strongest among participants living in areas with additional stressors, including heavy traffic noise or lower neighborhood income. Over a ten-year follow-up period, 17% of participants experienced major heart-related conditions.

A Stress Driven Pathway Linking Light and the Heart

“We found a nearly linear relationship between nighttime light and heart disease: the more night-light exposure, the higher the risk. Even modest increases in night-time light were linked with higher brain and artery stress,” Abohashem said. “When the brain perceives stress, it activates signals that can trigger an immune response and inflame the blood vessels. Over time, this process can contribute to hardening of the arteries and increase the risk of heart attack and stroke.”

Reducing Exposure at Home and in Communities

To lessen the impact of artificial light at night, Abohashem suggested that cities reduce unnecessary outdoor lighting, shield streetlamps, or install motion sensitive lighting systems. On an individual level, “people can limit indoor nighttime light, keeping bedrooms dark and avoiding screens such as TVs and personal electronic devices before bed,” he said.

Expert Perspective on Public Health Implications

“These findings are novel and add to the evidence suggesting that reducing exposure to excessive artificial light at night is a public health concern,” said Julio Fernandez-Mendoza, Ph.D., DBSM, FAHA, who serves on the writing committee of Multidimensional Sleep Health: Definitions and Implications for Cardiometabolic Health: A Scientific Statement From the American Heart Association.

Circadian Health and Cardiovascular Risk

Previously, the American Heart Association released a scientific statement on the Role of Circadian Health in Cardiometabolic Health and Disease Risk. The statement highlights light pollution as a major disruptor of the body’s internal clock and notes that it can suppress melatonin, delay the onset of sleep, and even at low levels has been linked to an increased risk of cardiovascular disease.

“We know too much exposure to artificial light at night can harm your health, particularly increasing the risk of heart disease. However, we did not know how this harm happened,” Fernandez-Mendoza said. “This study has investigated one of several possible causes, which is how our brains respond to stress. This response seems to play a big role in linking artificial light at night to heart disease.” Fernandez-Mendoza, who was not involved in the research, is also a professor of psychiatry, neuroscience, and public health sciences and director of behavioral sleep medicine at Pennsylvania State University College of Medicine in Hershey, Pennsylvania.

Strengths and Limitations of the Study

The research benefited from advanced PET/CT imaging to assess brain stress and arterial inflammation, combined with satellite-based measurements of nighttime light and long-term follow-up for cardiovascular events.

There were also limitations. The study was observational and relied on previously collected data, meaning it cannot establish a direct cause-and-effect relationship. In addition, all participants received care within a single hospital system, which limits the extent to which the findings can be generalized to more diverse populations.

Study Population and Data Sources

Researchers reviewed health records from 466 adults, 43% of whom were men, with a median age of 55. Among participants, 89.7% were white, and 10.3% were non-white. All underwent a PET/CT scan at Massachusetts General Hospital in Boston between 2005 and 2008.

Nighttime light exposure was estimated using data from the 2016 New World Atlas of Artificial Night Sky Brightness. This resource combines upward radiance measurements from the Visible Infrared Imaging Radiometer Suite Day/Night Band on the Suomi National Polar-orbiting Partnership satellite with radiative transfer modeling to estimate ground-level zenith sky brightness. Artificial brightness refers only to light produced by human sources and excludes natural light from stars, airglow, and moonlight.

Researchers measured nighttime light levels at each participant’s home and analyzed imaging markers of brain stress and arterial inflammation. Participants were followed through the end of 2018, during which time 79 individuals, or 17%, experienced major heart problems.

Looking Ahead

“This research indicates that light pollution is more than just an annoyance; it could also increase the risk of heart disease. We hope clinicians and policymakers will consider nighttime light exposure when developing prevention strategies,” Abohashem said. “We want to expand this work in larger, more diverse populations, test interventions that reduce nighttime light, and explore how reducing light exposure might improve heart health.”

What Actually Is Fire? The Answer Is Stranger Than You'd Think

30 December 2025, By E. BROWN, THE CONVERSATION

https://www.sciencealert.com/what-actually-is-fire-the-answer-is-stranger-than-youd-think

(TrueCreatives/Canva)

Fire is an ancient technology that has helped shape human evolution. Our ancestors used fire for safety, cooking, and preserving food. They gathered around a flickering fire to share stories, pass on cultural knowledge, and build community.

Today, fire is an important industrial tool. It remains woven into our daily lives and rituals (think blowing out candles on your birthday cake).

As it did millions of years ago, fire can shape our landscapes, having the power to both devastate and rejuvenate entire ecosystems.

Fire is so familiar, and yet it can be hard to define. What actually is fire?

Let's begin with a question that's a little easier to answer.

What are the ingredients for fire?

To light a fire we need three things: fuel (something to burn), oxygen, and an initial spark or heat source. This is known as the fire triangle, but you could also call the fuel and oxygen "reactants" and the initial heat the "activation energy".

For a bushfire, organic matter (such as wood) provides the fuel. Oxygen is available in the air, and the activation energy could come from a range of sources, such as lightning or human activities.


If we remove one of the reactants, a fire cannot continue to burn. To extinguish a bushfire, heat can be removed by dousing the fire with water. The water is turned into steam, which also smothers the fire by displacing air. Fuel may be used up by the fire itself or be preemptively removed using hazard-reduction or cultural burns.

Fire can be hard to define.

The main "product" of fire is energy, along with the gases carbon dioxide and water vapour. When there is more fuel than there is oxygen for burning, which is the case in a bushfire, there can be additional products.


One of them is soot, which is tiny, half-burned particles of carbon. These products interact to provide what we feel and see when we experience fire.

The warmth we feel from a fire comes from energy as it radiates outwards in the form of heat. The hot gas products rise because they are less dense than the surrounding, cooler air. The gases carry with them soot particles that glow yellow-orange because of their high temperature.

In a bushfire or campfire, it is the glowing soot that we experience as flames. Flames actually extend well above where we can see them. As the soot moves higher up, it cools and emits light in colours that we cannot see, such as infrared light.

So, what is fire?

It obviously isn't a liquid or a solid. While flames do involve hot gases, flames only exist while a fire is burning. They don't exist in a stable state on their own and we can't collect flames in a container like we could CO₂ or water vapour. Therefore, flames and fire are not gases.

We can also rule out plasma – the fourth state of matter. Plasma is similar to an extremely hot gas but with some key differences.

A plasma contains so much heat energy that atoms in the plasma become ionised, meaning they can no longer hold on to all of their electrons. The plasma is like a soup of charged particles, both electrons and ionised atoms, which can conduct electricity and respond to a magnetic field.

In the hottest parts of the most intense fires, it is possible that there are enough ionised atoms to form areas of weak plasma. However, the plasma is not stable on its own, and fire, as a whole, does not behave like a plasma.

In fact, fire is not matter at all. Fire is a process. It is a type of chemical reaction called combustion.

A process unique to Earth

Gasses and plasma are everywhere in the universe, but fire as we experience it – with visible, oxygen-fuelled flames – appears to be unique to Earth.

The Earth itself formed from dust and gas around a young Sun, which is so hot that it is almost entirely plasma. The universe is home to trillions of galaxies, each filled with stars and possible planetary systems, so there's a lot of gas and plasma out there.

Meanwhile, our Earth is the only place in the universe where fire is known to be possible.

That's because one of the key ingredients for fire – a stable supply of oxygen – is a byproduct of life. And as far as we know, life only exists here on Earth.

South Asia's Dairy Intolerance Could Help Explain Our Ability to Drink Milk

29 Dec. 2025, By M. STARR

https://www.sciencealert.com/south-asias-dairy-intolerance-could-help-explain-our-ability-to-drink-milk

Traditional buffalo herders of South Asia have unusually high lactose tolerance. 

(uniquely india/photosindia/Getty Images Plus)

A curious and paradoxical intolerance for lactose across the South Asian subcontinent could help explain why the ability for adults to consume fresh milk from other animals developed in other populations.

Researchers from the University of California, Berkeley, led a team of scientists in a genome-wide study of people across the Asian subcontinent to better understand how and why the ability to digest the sugar common in dairy products spread.

Despite being the world's biggest producers and consumers of dairy, most adults in India, Pakistan, and Bangladesh do not produce enough lactase, an enzyme that enables the digestion of lactose. Instead, dairy products in South Asia – such as ghee, yogurt, and other fermented products — are often lactose-reduced.

For many around the world, a variation in DNA near the lactase gene confers an ability to continue producing the enzyme well beyond infancy. It's believed that mutations responsible for this function emerged among pastoralists some 5000 years ago in what is now western Russia.

The recently-published study found that while the variant was introduced to the subcontinent during the historic and medieval periods, it failed to spread throughout South Asia's populations as it had in Europe.

Instead, natural selection barely moved the genetic variant, an allele called -13910*T, into the wider population at all – except in two small pastoralist communities, where it rose under some of the strongest known selection in recent human evolution.

Not all dairy products are high in lactose. 

(deepart386/E+/Getty Images)

In fact, "The strength of selection acting on this allele may have been higher in the South Asian pastoralist populations than in Northern Europeans," the researchers write in a preprint uploaded to bioRxiv.


"This is a great, careful, important study," anthropologist Christina Warinner of Harvard University, who wasn't involved in the research, told Science Magazine. "Our current explanation for how adult milk digestion works, and our understanding of lactose tolerance and intolerance, is really incomplete."

Humans produce lactase as infants to break down the lactose in their mother's milk. However, as children grow into adulthood, lactase production drops dramatically. If you can drink and digest lactose, you're in a global minority: an estimated 70 percent of the global population has a lactase deficiency to some degree, with wide variation between ethnic and age groups.

In some groups of people, the -13910*T allele allows high levels of lactase production well into adulthood. It's unclear how and why this trait spread globally, but scientists have often attributed it to natural selection in populations that consume a lot of dairy. Its low rate in South Asian populations, therefore, presents a bit of a puzzle.

Led by biologist Priya Moorjani of the University of California, Berkeley, a team of researchers assembled data from around 8,000 genomes, including present-day and ancient genetic material dating between 3300 BCE and 1650 CE.

They mapped the distribution of -13910*T across the South Asian subcontinent, finding a gradient from north to south.

The milk-drinking gene is significantly more common in the north, becoming more scarce the further south you go, with one glaring exception – the Toda (South India) and Gujjar (Pakistan) groups, traditional buffalo herders, in which lactase persistence was as high as 90 percent of the population.

Then, they traced -13910*T back through time to see when and where it emerged. They also compared long stretches of DNA around the allele from South Asian populations against other populations to find the closest match.

Both sets of data indicated that the gene variant had been introduced by pastoralists on the Eurasian Steppe, whose -13910*T haplotype was almost identical to that of South Asian populations.

Finally, the researchers simulated different ways the variant could have potentially persisted at elevated rates, from natural selection to genetic drift.

The explanation that best fits the data is that the gene was imported from the Eurasian Steppe and amplified by positive selection pressures. And its unusual strength in the Toda and Gujjar populations may have had something to do with their lifestyle. As buffalo herders, their diet depends heavily on fresh dairy, including fresh milk, butter, buttermilk, yogurt, and cheese.

Given that both the Toda and Gujjar traditionally rely heavily on fresh milk, their unusually strong, recent selection for the milk-drinking gene is consistent with an influence from dairy-dependent lifestyles.

"Our findings reveal that the evolution of lactase persistence is not a single narrative of selection," the researchers conclude, "but a mosaic of demographic and cultural histories, each leaving a distinct genetic imprint on the human genome."

World's Deepest Gas Hydrate Discovered Teeming With Life Off Greenland

29 Dec. 2025, By J. COCKERILL

https://www.sciencealert.com/worlds-deepest-gas-hydrate-discovered-teeming-with-life-off-greenland

(Panieri et al., Nature Communications, 2025)

A reserve of natural gas bubbling from a cage of ice discovered on the ocean floor to the west of Greenland may be the deepest gas hydrate cold seep on record, and it happens to be teeming with animal life.

The Freya gas hydrate mounds were discovered during the Ocean Census Arctic Deep EXTREME24 expedition, led by researchers from UiT The Arctic University of Norway and other partners. A water column gas flare alerted the researchers to unusual activity deep below their ship, prompting them to send a remotely operated vehicle (ROV) to investigate.

There, they encountered exposed mounds of a crystalline material known as a gas hydrate. The scientists guided the ROV to collect samples of the methane seepage and crude oil, along with sediment that contained a diversity of marine life.

"This discovery rewrites the playbook for Arctic deep-sea ecosystems and carbon cycling," says the expedition's co-chief scientist Giuliana Panieri.

"We found an ultra-deep system that is both geologically dynamic and biologically rich, with implications for biodiversity, climate processes, and future stewardship of the High North."

The deep-sea animals that call the Freya gas hydrate mounds home feed on chemosynthetic microbes that turn chemicals like methane, sulphide, and other hydrocarbons into biological fuel.

This is exactly what is seeping out of the seafloor at the newly discovered Freya mounds, far below the surface of the Greenland Sea: methane, and, to a lesser extent, heavier hydrocarbons.

One of the Freya hydrate gas mounds, with sample sites marked.

 (Panieri et al., Nature Communications, 2025)

With a steady supply of these chemicals leaking from the Earth's crust, the inhabitants of the Freya mounds are quite unbothered by the 3,640 meters (roughly 11,940 feet) of ocean above their heads. Who needs sunlight when you've got gas hydrates, which are a frozen mixture of methane and water, held in a crystal state by the high pressures and low temperatures of the deep ocean.

Nearly one-fifth of the world's methane is in the form of gas hydrate, locked in deep marine sediments.

Discovering the Freya mounds more than 3.5 kilometers below the surface is unusually deep for such a seep, though. Most on record are less than 2,000 meters underwater.

Animals discovered at the Freya mounds included 

tubeworms (b), shrimp-like crustaceans (c), bristle worms (d), and bivalves (g) 

(Panieri et al., Nature Communications, 2025)

The animals include siboglinid and maldanid tubeworms, skeneid and rissoid snails, and melitid amphipods. The ecosystem has a similar composition, at the family level, to Arctic hydrothermal vents at similar depths.

Compounds found in the sediment samples suggest the oil and possibly the gases originate from flowering plants that once grew in a warm, forested Greenland back in the Miocene, a geological epoch stretching from 23 to 5.3 million years ago.

These carbon-rich deposits are what make the Freya mounds such a great place to live (if you're a maldanid tubeworm or a melitid amphipod). It's also a key reason why the world's mining industry and some governments have their eyes on the deep Arctic.

"Despite significant progress in understanding the distribution and concentration of gas hydrates, a major challenge remains in evaluating gas hydrates as an energy resource and their role in global climate change," the authors note.

So far, deep-sea mining has primarily focused on polymetallic nodules; potato-size lumps found on the seafloor that contain rare earth minerals used in devices like smartphones. But it's unclear what effect such a disruption to the deep sea floor would have on marine ecosystems of our already-destabilized planet.

"There are likely to be more very-deep gas hydrate cold seeps like the Freya mounds awaiting discovery in the region, and the marine life that thrives around them may be critical in contributing to the biodiversity of the deep Arctic," says marine ecologist Jon Copley of the University of Southampton in the UK, who was part of the expedition.

"The links that we have found between life at this seep and hydrothermal vents in the Arctic indicate that these island-like habitats on the ocean floor will need to be protected from any future impacts of deep-sea mining in the region."

The Forgotten Genius of ElectroCulture

MARCH 7, 2025

https://omnicore.tech/blogs/news/the-forgotten-genius-of-electroculture-justin-christofleau-and-the-lost-science-of-atmospheric-energy-in-agriculture

In the early decades of the 20th century, as industrial agriculture marched toward synthetic fertilizers and mechanized efficiency, a visionary emerged with a radically different approach—one that harnessed the invisible forces of nature to nourish the soil and amplify plant growth. His name was Justin Christofleau, and his work in ElectroCulture—a method that utilized atmospheric and telluric electricity to stimulate agriculture—promised a revolution in farming.

Yet, despite his pioneering discoveries between 1910 and 1940, Christofleau’s research was overshadowed by the rise of chemical-based agribusiness. The agricultural world, lured by the convenience of synthetic fertilizers, turned away from the subtle but profound power of natural electrical forces. What followed was not just neglect but the active suppression of an entire branch of energy-based agricultural science—one that is only now beginning to resurface as the need for sustainable, non-toxic farming solutions becomes ever more urgent.

The Groundbreaking Experiments of Christofleau

Christofleau was not merely a theorist—he was an experimenter, an inventor, and a practical scientist whose methods yielded astonishing results. His work centered around three primary techniques:

• Metallic Conductors: Copper and zinc rods inserted into the soil channeled ambient electrical currents, invigorating root systems and microbial life.

• Atmospheric Antennas: Tower-like structures captured and redistributed electrical charges from the air, mimicking the natural effects of lightning on plant growth.

• Electro-Magnetic Soil Activation: Low-voltage electrical fields stimulated ion exchange and microbial activity, enhancing nutrient availability and soil health.

The results were nothing short of extraordinary:

• Accelerated Growth: Crops grew two to three times faster than under conventional methods.

• Enhanced Resilience: Plants displayed greater resistance to drought, disease, and pests due to increased nutrient absorption and vitality.

• Higher Yields: Some experiments recorded productivity increases of up to 200%.

• Improved Quality: Fruits and vegetables exhibited richer colors, superior taste, and higher nutritional value.

These findings were meticulously detailed in his seminal work, L’Agriculture Électrique, a comprehensive guide to ElectroCulture’s techniques and benefits.

The Science Behind ElectroCulture

At its core, ElectroCulture functioned by tapping into natural electrical currents that flow through the Earth and atmosphere—forces that modern physics acknowledges but industrial agriculture has largely ignored. The principles behind the method parallel concepts explored by Nikola Tesla, whose experiments in wireless energy transmission demonstrated that electrical fields could be harnessed and directed with precision.

Key insights from Christofleau’s research include:

• Plants Respond to Electricity: Scientific studies confirm that plants naturally react to electrical fields, often experiencing growth surges after thunderstorms. ElectroCulture replicates and enhances this effect in a controlled manner.

• Self-Sustaining Energy: Unlike chemical fertilizers that deplete soil health over time, ElectroCulture continuously regenerates the soil, fostering long-term vitality and sustainability.

The Visionaries Who Helped Pave the Way

Christofleau’s work did not exist in isolation. His discoveries were part of a broader exploration into the relationship between electricity, magnetism, and biological life. Several other pioneers—each a genius in their own right—helped lay the foundation for ElectroCulture and the understanding of nature’s hidden energetic forces:

• Georges Lakhovsky: A brilliant researcher in electromagnetic biology, Lakhovsky demonstrated that living cells resonate with natural cosmic and terrestrial frequencies. His Multiwave Oscillator was designed to amplify these vital energies, promoting cellular regeneration and plant vitality—concepts that align directly with Christofleau’s electro-agricultural principles.

• Viktor Schauberger: An Austrian naturalist and water researcher, Schauberger studied the energetic properties of vortex motion and its role in plant growth. He believed that the proper structuring of water and atmospheric energy could enhance fertility and revitalize soil ecosystems—an idea deeply connected to ElectroCulture’s goal of harnessing nature’s electrical forces.

• Derald Langham: A 20th-century scientist who expanded upon ElectroCulture techniques, Langham demonstrated that weak electrical fields could significantly boost plant metabolism, nutrient uptake, and overall vitality, providing modern validation for Christofleau’s work.

• Jagadish Chandra Bose: A pioneer in plant electrophysiology, Bose proved that plants respond to electromagnetic stimuli and even exhibit nervous system-like reactions. His work provided a crucial scientific framework for understanding how plants interact with subtle electrical energies.

• Nikola Tesla: Tesla’s studies in wireless energy transmission explored how atmospheric electricity could be harnessed for practical use. His concepts of free energy and non-invasive electrical stimulation parallel ElectroCulture’s vision of amplifying natural energetic flows to enhance plant growth.

Each of these visionaries contributed to a growing body of evidence that subtle electrical and vibrational energies are fundamental to life, capable of transforming agriculture, and key to unlocking a truly sustainable future.

Together, these minds helped construct a compelling body of evidence that subtle electrical forces could be harnessed to create thriving, resilient ecosystems—without the need for artificial inputs.

The Suppression of ElectroCulture and the Rise of Industrial Farming

Despite its promise, ElectroCulture was largely dismissed by the scientific establishment—a rejection driven not by a lack of efficacy but by economic and industrial pressures. The timeline of its decline follows a familiar pattern:

• Initial Enthusiasm: Christofleau’s patents and field trials in Europe sparked significant interest among progressive farmers.

• Industrial Resistance: As the chemical fertilizer industry gained dominance, powerful agricultural lobbies dismissed ElectroCulture as “unscientific” and impractical.

• Systematic Marginalization: Research into energy-based agriculture was ignored, ridiculed, or buried, ensuring that chemical-dependent farming became the global standard.

By the mid-20th century, ElectroCulture had faded into obscurity, preserved only in niche research and independent experimentation.

A Rediscovery for the Future of Agriculture

Today, as modern agriculture faces mounting crises—soil depletion, toxic runoff, declining crop nutrition, and climate instability—the principles of ElectroCulture offer a regenerative path forward. Revisiting Christofleau’s work could provide powerful solutions in areas such as:

• Sustainable Food Production: ElectroCulture techniques could dramatically increase crop yields without synthetic fertilizers or pesticides.

• Soil Restoration: By revitalizing microbial life and enhancing nutrient cycles, ElectroCulture restores soil health instead of depleting it.

• Food Security & Climate Resilience: Electrically enhanced plants demonstrate greater drought resistance and adaptability, offering a critical advantage in an era of ecological uncertainty.

As interest in bio-energetic agriculture resurfaces, Christofleau’s forgotten discoveries may yet spark a revolution—one that harmonizes with nature’s own energetic blueprint to redefine the future of farming.

Over 50% of Heart Attacks in Younger Women Aren't From Clogg

28 Dec 2025, By D. NIELD

Traditionally, most heart attacks have been blamed on clogged arteries causing atherothrombosis – where blood clots block flow to the heart.

But research suggests we may be underestimating the role of other causes, particularly in younger adults.

Scientists from the Mayo Clinic in the US analyzed 1,474 heart attack events in people aged 65 or younger, recorded between 2003 and 2018 in Olmsted County, Minnesota. By carefully reviewing medical records and imaging, they identified a primary cause behind each case.

Strikingly, more than half of heart attacks in women were found to have non-atherothrombotic causes.

https://www.youtube.com/watch?v=7-rAKQq-fhQ

Atherothrombosis accounted for 75 percent of heart attacks in men, which wasn't surprising. But in women, it was behind 47 percent – less than half. That has major implications for the prevention and treatment of heart attacks.

"This research shines a spotlight on heart attack causes that have historically been under-recognized, particularly in women," says cardiologist Claire Raphael.

"When the root cause of a heart attack is misunderstood, it can lead to treatments that are less effective – or even harmful."

In women, 34 percent of all heart attack events were attributed to supply/demand mismatch secondary myocardial infarctions (SSDMs) – defined as an imbalance of oxygen supply and demand caused by other stressors on the body, such as anemia or an infection.

Among the other factors significantly contributing to heart attacks were spontaneous coronary artery dissections (SCADs), where tears in artery walls collect blood, and embolisms (blood clots traveling from other areas of the body).

Among people under 65, there were significant differences in heart attack causes between men and women. (Raphael et al., J. Am. Coll. Cardiol., 2025)



"In women aged 45 years or younger, SSDM was the most common cause," write the researchers in their published paper.

"And the acute non-atherothrombotic coronary causes (SCAD, embolism, spasm, and MINOCA-Undefined) were collectively as common as atherothrombosis."

People who experienced SSDMs had the highest rates of death from any cause in the following 5 years, which the authors suggest "likely relates to a sicker population who are more likely to die from their underlying non-cardiac diseases."

The team also found that many SCAD-related heart attacks were initially misattributed to atherothrombosis, especially in women, where SCAD was the cause nearly six times as frequently.

If heart attack causes are misdiagnosed, then doctors might take the wrong approach to trying to prevent the next one.

"Our research highlights the larger need to rethink how we approach heart attacks in this patient population, and for younger adult women, in particular," says cardiologist Rajiv Gulati.

"Clinicians must sharpen their awareness of conditions like SCAD, embolism, and stress-related triggers, and patients should advocate for answers when something doesn't feel right."

This study didn't explore the significant difference here between men and women, but it could be the result of heart attack risk factors affecting women differently, or women being less likely to seek medical help.

That's something that future research can look into, as well as using the same analysis techniques across larger and more diverse groups of people.

In the US, someone experiences a heart attack every 40 seconds, and work continues to try and understand as much as we can about the risk factors, which include city living, diet, and air pollution.

The good news is, as the team notes, we are getting better at spotting, diagnosing, and preventing heart attacks from recurring. Significant progress has been made in heart imaging technology, for example, over the study period.

That said, new research from the US and Canada shows current medical screening techniques could still be failing to catch nearly half of those who experience a heart attack.

In the US, heart attack risk is typically assessed according to a set of criteria such as an atherosclerotic cardiovascular disease (ASCVD) score, which measures factors linked to the development of cardiovascular disease. Patients are then monitored or treated if their scores exceed a certain threshold.

An analysis of the health records of 465 people aged 65 years or younger who were treated for their first heart attack found that two days before the event, ASCVD scores would have categorized 45 percent of them as being at low or borderline risk levels.

Raphael, Gulati, and their colleagues now want to see more done to raise awareness of the alternative causes behind heart attacks, both with health professionals and the public, which could ultimately save lives.

"Understanding why a heart attack happened is just as important as treating it," says Raphael. "It can mean the difference between recovery and recurrence."

Researchers analyzing ancient sewer drains at the Roman fort of Vindolanda near Hadrian’s Wall have found clear evidence that people living at the site were infected with three intestinal parasites: roundworm, whipworm, and Giardia duodenalis.

All three parasites spread through poor sanitation, typically when food, water, or hands are contaminated with human feces. Roundworms can grow to 20-30cm in length, while whipworms reach about 5cm. Giardia duodenalis is a microscopic protozoan parasite known for causing outbreaks of diarrhea. This discovery marks the first confirmed evidence of Giardia duodenalis in Roman Britain.
Vindolanda and Rome’s Northern Frontier

Vindolanda was located near Hadrian’s Wall in what is now northern England. Hadrian’s Wall was built by the Romans in the early 2nd century AD to protect the province of ‘Britannia’ from northern tribes and remained in use until the late 4th century. The fort itself sits between Carlisle and Corbridge in Northumberland, Britain.

The wall stretches east to west from the North Sea to the Irish Sea and was built with forts and towers placed at regular intervals. These defenses were manned by infantry, archers, and cavalry units drawn from across the Roman Empire.

A Site Known for Exceptional Preservation

Vindolanda is well known for the remarkable preservation of organic materials within its waterlogged soil. Archaeologists have uncovered more than 1,000 thin wooden writing tablets that record daily life at the fort, along with over 5,000 Roman leather shoes.
How the Sewer Samples Were Studied

The parasite investigation focused on sediment collected from a sewer drain connected to a latrine block at a 3rd century CE bath complex. The work was carried out jointly by researchers from the universities of Cambridge and Oxford and published in the journal Parasitology.

Scientists collected 50 sediment samples along the drain, which measured about nine meters and carried waste from the communal latrine to a stream north of the fort. Objects recovered from the drain included Roman beads, fragments of pottery, and animal bones.

The samples were divided between laboratories at Cambridge and Oxford, where researchers examined them under microscopes to search for ancient helminth eggs. Helminths are parasitic worms that infect humans and other animals.

Evidence of Worms and Giardia Infection

About 28% of the samples contained eggs from either roundworm or whipworm. One sample showed evidence of both species. That same sample was further tested using a bio-molecular method known as ‘ELISA’, which works by using antibodies that bind to proteins produced by single-celled organisms. This test revealed traces of Giardia duodenalis.

The research team also examined sediment linked to an earlier fort dating to the 1st century CE. That fort was built around 85 CE and abandoned by 91/92 CE. The sample came from a ditch that formed part of the fort’s defensive system and contained both roundworm and whipworm eggs.

How Parasites Affected Roman Soldiers

“The three types of parasites we found could have led to malnutrition and cause diarrhea in some of the Roman soldiers,” said Dr. Marissa Ledger, who led the Cambridge portion of the study as part of her PhD at the University of Cambridge’s Department of Archaeology.

“While the Romans were aware of intestinal worms, there was little their doctors could do to clear infection by these parasites or help those experiencing diarrhea, meaning symptoms could persist and worsen. These chronic infections likely weakened soldiers, reducing fitness for duty. Helminths alone can cause nausea, cramping, and diarrhea.”

Study senior author Dr. Piers Mitchell, an Affiliated Scholar at Cambridge’s McDonald Institute for Archaeological Research, explained that Giardia could have caused serious illness during warmer months. “Some soldiers could have become severely ill from dehydration during summer outbreaks of Giardia, which are often linked to contaminated water and can infect dozens of people at a time. Untreated giardiasis can drag on for weeks, causing dramatic fatigue and weight loss.”

Mitchell also noted that “The presence of the fecal-oral parasites we found suggests conditions were ripe for other intestinal pathogens such as Salmonella and Shigella, which could have triggered additional disease outbreaks.”

How Vindolanda Compares to Other Roman Sites

According to the researchers, the dominance of fecal-oral parasites at Vindolanda closely matches findings from other Roman military sites, including Carnuntum in Austria, Valkenburg on Rhine in the Netherlands, and Bearsden in Scotland. In contrast, large Roman cities such as London and York show a wider variety of parasites, including fish and meat tapeworms.

“Despite the fact that Vindolanda had communal latrines and a sewer system, this still did not protect the soldiers from infecting each other with these parasites,” said Dr. Patrik Flammer, who analyzed samples at the University of Oxford.

What Ancient Parasites Reveal About Roman Life

“The study of ancient parasites helps us to know the pathogens that infected our ancestors, how they varied with lifestyle, and how they changed over time,” said Prof Adrian Smith, who led the Oxford laboratory involved in the research.

Dr. Andrew Birley, CEO of the Vindolanda Charitable Trust and leader of ongoing excavations at the site, said the findings continue to reshape our understanding of life on Rome’s northern frontier. “Excavations at Vindolanda continue to find new evidence that helps us to understand the incredible hardships faced by those posted to this northwestern frontier of the Roman Empire nearly 2,000 years ago, challenging our preconceptions about what life was really like in a Roman frontier fort and town.”

W. H. Auden’s well-known poem about a miserable Roman soldier guarding a rain-soaked wall in northern Europe mentions “lice in my tunic and a cold in my nose.” Based on this research, serious stomach trouble could easily be added to that list.
