Queen bees have a disturbing way to survive pesticides

Honeybee queens exposed to pesticides can shift some of the contamination into their eggs, revealing a previously unknown survival strategy. The process may protect the queen while putting developing offspring, and potentially the entire colony, at risk.

Tooth count may predict survival after pancreatic cancer surgery

Pancreatic cancer patients with at least 21 natural teeth survived nearly two years longer after surgery than those with fewer teeth in a study of 339 people. Researchers suspect tooth loss may reflect decades of inflammation, frailty, nutrition, and other factors tied to the body’s overall resilience.

Archaeologists discover mysterious 400-year-old Indigenous pot in Florida

A tiny, fully intact Indigenous pot buried for roughly 400 years has left archaeologists wondering why such a usable object was deliberately abandoned. Found at a historic Potano-Timucua village in Florida, the mysterious vessel is helping reveal a complex world of Native traditions, Spanish influence, trade, and migration.

This gut microbe may help keep you strong as you age

Scientists have linked a specific gut bacterium, Roseburia inulinivorans, to stronger muscles in both humans and mice. Older adults who carried it had 29% greater handgrip strength, while treated mice gained about 30% more grip strength and developed larger, more fast-twitch muscle fibers. The bacterium was also less common in older people. Researchers say it could eventually become a probiotic candidate for helping combat age-related muscle loss.

NASA Shares Views of August Solar Eclipse from Ground, Air, Space

On Aug. 12, a total solar eclipse darkened skies over Greenland, Iceland, and Spain. As the Moon covered the Sun, it briefly revealed the Sun’s wispy outer atmosphere — the corona — to those in the path of totality who were lucky enough to have clear skies. NASA researchers and photographers were along the eclipse […]

3 minutes of sprinting does something 90 minutes of exercise does not

A few minutes of sprinting may reshape the bloodstream far more dramatically than a much longer moderate workout. Six 30-second sprints altered nearly a quarter of the blood proteins measured and more than 200 metabolites, while 90 minutes of moderate cycling produced far smaller immediate changes. Many of the proteins affected by sprinting were also associated with lower risks of obesity, type 2 diabetes, and other metabolic diseases.

Scientists catch a hidden electronic state forming in just 30 femtoseconds

Scientists watched a light-triggered hidden state form inside a material in only 30 femtoseconds, revealing a step that had never been seen before. The material first entered a fleeting electronic state in which its bonds reorganized in a repeating pattern, followed by tiny atomic shifts. This ultrafast pathway could offer a new way to control electronic properties with light and help inspire faster, more responsive technologies.

This weight-loss hormone may protect the liver even without weight loss

A hormone already known for curbing appetite and supporting weight loss may have a surprising second job: protecting the liver from inflammation and scarring. Researchers at McMaster University found that GDF15 activates a previously unknown brain-to-liver pathway that triggers the release of glucocorticoids, helping calm immune activity in the liver.

AI may know how you’ll respond to a vaccine before you get it

AI may be able to predict how strongly someone will respond to a vaccine before they receive it. By analyzing antibody patterns in more than 4,000 people, researchers found signs of “immune readiness” that helped distinguish strong responders from weak ones. Surprisingly, even some healthy people responded poorly, while some immunosuppressed people mounted strong responses.

Hidden magnetism inside atoms may explain mysterious gamma rays

For decades, scientists have puzzled over why certain atomic nuclei unexpectedly produce large numbers of low-energy gamma rays. A new experiment traced the effect to magnetic changes inside the nucleus, where protons and neutrons effectively flip their tiny internal magnets. The discovery could sharpen models of everything from nuclear reactions on Earth to the creation of heavy elements in stars and neutron star mergers.
