Ancient DNA reveals farming spread through migration, locals slow to adopt it
2025-08-27
UNIVERSITY PARK, Pa. — Roughly 10,000 years ago, humans started shifting from being nomadic hunter-gatherers to building large agricultural settlements, marking one of the greatest transformations in human history. This transition, known as the Neolithic Revolution, began in the Fertile Crescent of the Middle East and led to the spread of farming throughout Europe. For decades, researchers have debated what drove this change. Did farming spread mainly because farmers themselves moved into new lands, ...
Researchers turn mouse scalp transparent to image brain development
2025-08-27
During childhood and adolescence, our brain goes through a lot of changes. But studying those changes in juvenile mice is challenging because scientists don’t have a way to repeatedly image the same animal’s neural pathways as they grow.
Now, by simply rubbing a solution into a juvenile mouse’s scalp, researchers at Stanford can make the skin transparent to all visible light, allowing them to image the developing connections in a living mouse’s brain. And because the technique is reversible and non-invasive, the researchers can return to the same animal over days and weeks. The work, published Aug. ...

Wheat that makes its own fertilizer
2025-08-27
Scientists at the University of California, Davis, have developed wheat plants that stimulate the production of their own fertilizer, opening the path toward less air and water pollution worldwide and lower costs for farmers.
The technology was pioneered by a team led by Eduardo Blumwald, a distinguished professor in the Department of Plant Sciences. The team used the gene-editing tool CRIPSR to get wheat plants to produce more of one of their own naturally occurring chemicals. When the plant releases the excess chemical into the soil, the chemical helps certain bacteria in the soil convert nitrogen from the air into ...

2025-08-27
MINNEAPOLIS — A new study found that Native Hawaiian or Pacific Islander people had the highest rate of stroke among people from other race and ethnic groups, with a rate more than three times higher than that of white people. The study is published on August 27, 2025, in Neurology®, the medical journal of the American Academy of Neurology.
“Multiple studies have shown racial and ethnic disparities in the rate of stroke in the United States, but there is little information on the rate among Native Hawaiian or Pacific Islander people, especially ...
Scientists reveal warped protoplanetary discs, reshaping ideas about how planets form
2025-08-27
The textbook picture of how planets form – serene, flat discs of cosmic dust – has just received a significant cosmic twist. New research, published in the Astrophysical Journal Letters, is set to reshape this long-held view. An international team of scientists, wielding the formidable power of the Atacama Large Millimetre/submillimetre Array (ALMA), has found compelling evidence that many protoplanetary discs, the very birthplaces of planets, are in fact subtly warped.
These slight bends and twists in the disc plane, often just a few ...
Be it feast or famine, orangutans adapt with flexible diets
2025-08-27
Humans could learn a thing or two from orangutans when it comes to maintaining a balanced, protein-filled diet.
Great apes native to the rainforests of Indonesia and Malaysia, orangutans are marvels of adaptation to the vagaries of food supply in the wild, according to an international team of researchers led by a Rutgers University-New Brunswick scientist. The critically endangered primates outshine modern humans in avoiding obesity through their balanced choices of food and exercise, the scientists found.
The researchers reported their findings, based on 15 years of firsthand observations of wild orangutans ...

New crocodile-relative “hypercarnivore” from prehistoric Patagonia was 11.5ft long and weighed 250kg
2025-08-27
A newly-discovered species of a large, crocodile-relative predator has been described via a remarkably well-preserved fossil from Argentina, according to a study published August 27, 2025, in the open-access journal PLOS One by Fernando Novas from Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Argentina, and colleagues.
The Chorrillo Formation formed around 70 million years ago, during the Maastrichtian age at the very end of the Cretaceous period. At this time, southern Patagonia was a warm, seasonally humid landscape of freshwater floodplains, home to creatures like dinosaurs, turtles, frogs, and various mammals.
The new fossil unearthed in this formation is ...
“Unhappiness hump” in aging may have disappeared worldwide
2025-08-27
A new survey-based study suggests that the “unhappiness hump”—a widely documented rise in worry, stress, and depression with age that peaks in midlife and then declines—may have disappeared, perhaps due to declining mental health among younger people. David Blanchflower of Dartmouth College, U.S., and colleagues present these findings in the open-access journal PLOS One on August 27, 2025.
Since 2008, a U-shaped trend in wellbeing with age, in which wellbeing tends to decline from childhood until around age 50 before ...

Children’s Hospital of Philadelphia researchers link dietary fats to more severe form of asthma
2025-08-27
Philadelphia, August 27, 2025 – Researchers at Children’s Hospital of Philadelphia (CHOP) found that certain lipids, or fats, in obesity-causing foods also cause asthma-like lung inflammation. The findings suggest that in addition to modifying dietary choices, certain existing drugs could be repurposed to help treat this type of asthma. The findings were published online today by the journal Science Translational Medicine.
The study was prompted by researchers noticing an association between childhood obesity and neutrophilic asthma, a non-allergic type of asthma triggered ...

Overworked brain cells may burn out in Parkinson’s disease
2025-08-27
SAN FRANCISCO—Certain brain cells are responsible for coordinating smooth, controlled movements of the body. But when those cells are constantly overactivated for weeks on end, they degenerate and ultimately die. This new observation made by scientists at Gladstone Institutes may help explain what goes awry in the brains of people with Parkinson’s disease.
Researchers have long known that a particular subset of neurons die as Parkinson’s disease progresses, but they aren’t sure why. The new work, published in the scientific journal eLife, shows that in mice, chronic activation of these neurons can directly cause their demise. The scientists hypothesize ...
One in seven bariatric surgery patients turn to new weight loss drugs
2025-08-27
Bariatric surgery is usually effective on its own for weight loss, but an increasing proportion of patients who undergo bariatric surgery start taking one of the new glucagon-like 1 peptide receptor agonist (GLP-1) weight-loss drugs in the years after their surgery, according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health.
The researchers analyzed de-identified national electronic health records covering 112,858 individuals who underwent bariatric surgery from January 2015 to May 2023. They found that 14% of those patients used a GLP-1 such ...
A nonsurgical path to treating pelvic organ prolapse
2025-08-27
Pelvic organ prolapse (POP) is a disorder that primarily affects older women who have experienced multiple vaginal childbirths.
Repeated vaginal deliveries can cause the muscles and connective tissue that hold the pelvic organs—the vagina, bladder, uterus, urethra, and rectum—to weaken, causing one or more of the organs to drop out of position and bulge or extrude outside the body.
“There’s a breakdown and loss of the elastic matrix which contributes to tissue elasticity, similar to how a rubber band can stretch and recoil,” says Lehigh University ...
Electrons reveal their handedness in attosecond flashes
2025-08-27
We have all been familiar since childhood with the fact that our left and right hands are identical in structure but not in shape. They are mirror images of each other. In everyday life, this means that a left-handed glove does not fit on the right hand.
This “handedness” is also a fundamental property of matter: similar to our hands, many molecules exist in two mirror-image versions, which, despite looking confusingly similar, are actually not identical. Chemists call this chirality.
The distinction between right- and left-handed chiral molecules ...
