Astronomers using JWST have discovered that massive early galaxies contain far more small, faint stars than expected. That hidden population could make some of these galaxies three to four times more massive than previous estimates. The finding makes it even harder to explain how enormous, mature galaxies formed so soon after the Big Bang. It could also suggest that planets around low-mass stars were more common in the early universe than scientists realized.

Exercise may not be a powerful weight-loss tool on its own, but it appears to play a much bigger role in preventing lost weight from returning. By preserving muscle, supporting metabolism, improving fat burning, and regulating appetite and blood sugar, regular activity can make long-term weight maintenance easier.

Peppermint oil may have an unexpected benefit for people with mildly high blood pressure. Adults who took a small dose twice daily for 20 days saw their systolic blood pressure fall by an average of 8.5 mmHg, while a placebo group showed little change. Researchers say the inexpensive oil could eventually provide a simple additional option for managing elevated blood pressure.

A simple yeast-based food supplement may help restore the immune system’s ability to fight cancer, according to new research in mice. Scientists found that yeast beta-glucan reprogrammed early immune cells in the bone marrow, leading to stronger, longer-lasting cancer-fighting responses against colorectal, skin, and breast cancer cells.

Freezing the liquid core of an optical fiber produced an extreme environment where light and sound interact more than 1,000 times more strongly than in ordinary fibers. Researchers used the effect to create optoacoustic memory, potentially paving the way for lower-energy photonic computers and advanced quantum technologies.

People who speak several languages may have brains that age more slowly, with four-language speakers showing brains that appeared about 13 years younger than those of monolinguals. Starting earlier and becoming highly fluent were also linked to a stronger effect.

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.

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.

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.

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.

Jodi Ettenberg on living grief and a serendipitous discovery. “Living grief lacks the tapestry of rituals, language, and social permissions around grieving that a person is offered with death.”

Jon Husted's pitch: electricity prices are high because Obama and Biden closed 23 Ohio power plants — half the state's power supply, he claims — all in the name of "radical climate policies." Supply and demand did the rest. Never mind that utilities at the time cited cheap...
