Tiny nutrient, big mystery: Key gene reveals how cereal crops transport nickel

Nickel plays an important physiological role in plants, but how it is transported over long distances from stems and leaves to grains was poorly understood for more than 50 years. Now researchers have identified a key transporter gene, ZmNAET1, that controls nickel accumulation in cereal grains.

How cells pull together: Theoretical study reveals a hidden source of attraction

Imagine two people standing on a stretchy sheet. When one pulls, the other feels the fabric move and responds with a pull of their own. Each adjustment changes what the other feels. Something similar happens between living cells. They tug on the material around them, sense the stretching caused by their neighbors and adjust their own forces.

Gatineau Park foliage reveals local Cold War nuclear testing legacy

For more than six decades, local scientists have collected sugar maple leaves from Gatineau Park to measure their radiocarbon levels, creating the longest continuous record of its kind. Now, a study of those leaves led by the André E. Lalonde National Facility for Accelerator Mass Spectrometry (AEL-AMS) located at the University of Ottawa shows that the effects of Cold War–era nuclear weapons testing have only recently disappeared from the local biosphere. The study, titled "Stored carbohydrates buffer Bomb and Suess radiocarbon effects in maple leaves across a 65-year Ottawa region record," was published in Scientific Reports.

Machine learning reveals how often fish schooling evolved—and repeatedly disappeared

Scientists have used new machine learning techniques to investigate a topic no one has ever found a way to study: the evolution of fish moving together in schools across thousands of species. The new paper, published Nov. 6 in the Proceedings of the National Academy of Sciences, is among the largest studies of the evolution of any behavior ever conducted in any group of species, according to the authors. The research shows that behaviors, which have previously been difficult to quantify, can be studied at a large evolutionary scale.

Subaru Telescope reveals the shape and temperature of Comet Encke's nucleus

Mid-infrared observations with the Subaru Telescope have revealed the shape and surface temperature of the nucleus of Comet 2P/Encke. By analyzing how the nucleus's thermal emission changed as it rotated, the researchers found that the nucleus is elongated, with a long axis of about 7 kilometers and a short axis of about 3 kilometers. They also determined that the surface temperature at the time of observation was 328 ± 7 Kelvin (about 55°C).

An ancient ocean full of giant predators reveals a surprising twist in evolution

A remarkable fossil discovery in Colombia is challenging how scientists understand major evolutionary changes in Earth's history. Researchers uncovered an incredibly diverse ancient marine ecosystem where giant reptiles, sharks, and other creatures thrived as older evolutionary groups approached extinction and newer ones emerged. They call this previously unrecognized pattern a "Biotic Inflection," suggesting that major transformations in life can occur without mass extinctions.

Ancient Siberian tomb reveals surprising secrets of cannabis use 2,800 years ago

Scientists investigating a 2,800-year-old Siberian tomb discovered roughly 1,000 cannabis seeds and chemical evidence suggesting ancient Scythians used the plant for its intoxicating effects. The remarkable find, surrounded by evidence of elaborate burial rituals and animal sacrifices, offers the oldest directly dated archaeological evidence of psychoactive cannabis use.

Magic mushrooms rewire the brain in a way scientists didn't expect

A surprising discovery reveals how psilocybin, the active compound in magic mushrooms, rapidly reshapes the brain by creating new neural connections and strengthening them. Researchers found that the drug behaves differently in healthy and chronically stressed mice, potentially helping repair brain circuits damaged by prolonged stress. Most intriguingly, they identified a way to trigger this brain rewiring without the behavioral response associated with psychedelic effects.

Astronomers deliver the sharpest and deepest view yet of the low-frequency radio sky

Using the Low Frequency Array (LOFAR), an international team led by Leiden University has produced the sharpest and most sensitive radio image of the sky ever made at low radio frequencies. The image reveals almost 63,000 radio sources, such as active galactic nuclei and star-forming galaxies, across a patch of sky about 25 times the area of the full moon. The results have been accepted for publication in Astronomy & Astrophysics. The paper is currently available on the arXiv preprint server.

Origin of Stonehenge’s altar remains enigma as north-east Scotland theory ruled out

Geologists say they are getting closer to solving mystery as tests suggest stone may have come from elsewhere in Scotland, northern England or even Ireland They spent countless hours on weather-battered Scottish hills, a hardy band of geologists searching for the origin of one of Stonehenge’s most intriguing features. But the prehistoric monument tends to yield its secrets reluctantly, and a new scientific report reveals that the origin of Stonehenge’s altar stone remains elusive – and the wind-whipped geologists may very well have been looking in the wrong spot anyway.

Ultrasound reveals hidden tongue movements behind centuries-old language change

Scientists at Lancaster University have observed the hidden tongue movements accompanying a centuries-old change in English speech—offering a rare glimpse of language transforming in real time. Linguists have used ultrasound imaging to observe one of these changes as it unfolds inside the mouths of speakers from Blackburn, Lancashire—one of the few places in England where many older speakers still pronounce the historical strong-R sound after vowels in words like star and heart.

Molecular imaging reveals how shape-shifting protein complex captures DNA and holds separate sections together

Researchers at Kanazawa University and the National Institute of Genetics in Japan have used high-speed atomic force microscopy to observe how a group of proteins known as Smc5/6 interacts with DNA. The images reveal how this structure opens and closes, captures DNA and brings separate sections together. The researchers also observed Smc5/6 holding twisted sections of DNA in place, producing more tightly packed arrangements. The findings, published in Nature Communications, provide new insights into the molecular processes that contribute to the maintenance and repair of genetic material.

The next global pandemic could be brewing on a mink farm in Utah – and little is being done to stop it | George Monbiot

Mink farms are the perfect petri dishes for deadly flu strains to emerge. Yet officials appear to be protecting business interests over human lives Could this be ground zero? Could it be the spot where the next pandemic begins? It’s certainly a candidate, not least because the chain of events that could trigger a plague far worse than Covid-19 looks like the opening sequence of a disaster movie. A really bad disaster movie, in which the levels of carelessness and turpitude defy belief. A report by the investigative news service ProPublica reveals that bird flu has been raging in a mink farm in Utah since August, and it appears next to nothing has been done by public officials. In 2023, I warned in the Guardian that mink farms could scarcely be better designed to generate lethal plagues. This is for three reasons: mink are fed on the offcuts of chickens, cows and other farm animals, in which new viral variants often develop; mink readily host both avian and human flu viruses, which can then exchange genetic material, turning a bird disease into a human one; and mink possess extremely high “zoonotic potential” – the ability to infect animals of other species, including human beings. George Monbiot is a Guardian columnist Continue reading...

Boat burial reveals leprosy strain in fifth-century Germany

Visigothic and Vandal forces marched into Italy and conquered Rome; the Huns spread fear and terror on their campaigns through Western Europe; the Franks expanded their domain southward—the fifth century was an era of profound, often violent upheavals in Europe, and at the same time one of great mobility. Researchers from the Institute of Clinical Molecular Biology (IKMB) at Christian-Albrechts-University in Kiel and the Lower Saxony Institute for Historical Coastal Research (NIhK) have now identified a specific example of this mobility in the Fallward burial ground in what is now the district of Cuxhaven.
