Climate change makes pollen scarce, starving honeybees. A new supplement made from engineered yeast that contains specific beneficial fats may help young honeybees thrive.

But extreme weather and shifts in plants’ flowering periods have made pollen scarce, causing them to starve.Elynor Moore is a synthetic biologist at Delft University of Technology. At the time of the study, she was a graduate student in the laboratory of Geraldine Wright, a bee researcher at the University of Oxford.

“Even though there were long periods of inactivity, the Hadza are often resting in postures that require their muscles to maintain light levels of activity,” explains professor and researcher David Raichlen, Ph.D. “Being a couch potato—or even sitting in an office chair—requires less muscle activity. Since light levels of muscle activity require fuel, which generally means burning fats, then squatting and kneeling postures may not be as harmful as sitting in chairs.”

Grinstein, PhD, North American Editor of Inside Precision Medicine, hosts a new series called Behind the Breakthroughs that features the people shaping the future of medicine. With each episode, Jonathan gives listeners access to his guests’ motivational tales and visions for this emerging, game-changing field. When a rare genetic mutation left baby KJ without a viable treatment option, scientists and regulators faced an ethical and scientific crossroads: should medicine move fast enough to save a single child? Vanessa Almendro-Navarro, PhD, saw in KJ’s case both an urgent humanitarian mission…
Getting enough protein and fiber in your diet can help with weight loss.Prepared foods can be a helpful tool when trying to eat well and support weight loss.Your overall lifestyle—beyond just diet and exercise—is important for weight loss success. Between work, after school activities and maintaining a social life, trying to find the time to meal prep might be the last thing on your mind. This is where a busy person best friend comes in: prepared foods. But not all prepared foods are created equal—especially if you’re aiming to support weight loss or meet specific nutrient needs. If you’re trying…
We lift weights to build muscles, head to pilates class to tone them, and foam roll or use a massage gun to help relieve tension. But there’s a muscle that many women don’t know they need to pay attention to until something goes awry—the pelvic floor.
Luke TaylorRio de JaneiroAt least 57 people, including 22 women and 17 children, have been killed in northern Darfur in Sudan after a camp hosting displaced families was bombed on Saturday, Unicef has said.1The drone strike on the Dar al-Arqam displacement centre in the city of El Fasher in North Darfur state has been widely attributed to the Rapid Support Forces (RSF), a paramilitary group that has been openly at war with Sudan’s national army since April 2023.2The Sudan Doctors Network said on Saturday that the attack “was not an accidental incident, but rather a full blown genocide being carried…
Next week will see a first in computer science, with the launch of a scientific conference in which all of the papers — and all of the reviews — have been produced by machines.At the event known as Agents4Science 2025, to be held online on 22 October, the attendees will still be humans. It will feature presentations of the submitted papers — given either by the artificial intelligence (AI) agents themselves or by the humans who ran the experiments — and panel discussions by academics.The conference offers “a relatively safe sandbox where we can sort of experiment with different submission…
Off a quiet hallway on the top floor of a building at the University of Osaka in Japan, Katsuhiko Hayashi is hatching a revolution.Human embryo science: can the world’s regulators keep pace?He is on a decades-long quest to grow eggs and sperm in the laboratory. Hayashi wants to understand the fundamental biology of these reproductive cells. But, if he succeeds, it could forever alter how humans reproduce.Even for a scientist known for extreme doggedness, it has been a tortuous road. It has taken Hayashi to some strange places: his lab grows fragments of faux ovaries and testes in dishes and…
A new observational study involving retrospective analysis of serum samples from 33,029 individuals from the UK indicates that almost one in 10 women were anemic, and one third had absolute iron deficiency, despite being part of a health-aware population.Samples from people who had privately visited a Randox Health Clinic within the UK for a health check between January 2022 and May 2024 were retrospectively analyzed to identify the prevalence of anemia and iron deficiency. Writing in Frontiers in Nutrition, the researchers from Randox Health, Ulster University and Antrim Hospital, UK, posed the question, “should there be a national screening programme…
SEATTLE – “Proteins are these beautiful and strange mysteries of nature,” described Nobel Laureate, David Baker, PhD, to an audience of fundraiser donors at the Amazon Meeting Center in downtown Seattle. “For many years, the only proteins we knew were the proteins that were found in nature. In the last 10 years, we’ve figured out how to design new proteins to solve the problems that are facing humanity today.” Baker, who is the director of the Institute for Protein Design at the University of Washington (UW) and a Howard Hughes Medical Institute (HHMI) investigator, was awarded the 2024 Nobel Prize in Chemistry for…
