A little movement in midlife could pay off for your brain years later

Exercise and healthy blood sugar levels in midlife may help slow cognitive decline decades later. Physical activity appeared especially beneficial for Mexican American adults, suggesting that some brain-protective factors may differ across populations.

The common mistake that could make aging joints hurt more

Aging gradually wears down the cartilage and fluid that protect our joints, but avoiding movement may actually make matters worse. Exercise helps nourish cartilage, strengthens the muscles that protect joints, and can reduce osteoarthritis pain. Low-impact activities such as swimming, cycling, tai chi, yoga, and walking on varied terrain may also improve balance and mobility. Even a few minutes of the right kind of movement can make a difference.

Physicists discover a hidden gluon structure inside protons that could rewrite textbooks

Physicists may have uncovered a hidden feature inside protons that helps preserve one of matter’s most fundamental properties. RHIC collision data suggest baryon number is carried not simply by three quarks, but by a Y-shaped junction of the gluons connecting them. The finding challenges a decades-old textbook picture and could deepen our understanding of why protons—and ultimately matter itself—remain stable.

Scientists reveal why walking gets so much harder with age

As we age, the body appears to sacrifice walking efficiency in exchange for stability. Older adults stiffen the ankle more with each step, which may help prevent falls but also forces the muscles to work harder while producing less forward motion. This leads to shorter strides, slower walking, and faster fatigue. Exercises targeting balance, coordination, and lower-leg strength could help preserve mobility.

A new Ice Age species was hiding in la brea tar pits fossils for decades

Scientists have discovered a new extinct amphibian species hiding in the fossil collections of Los Angeles’ La Brea Tar Pits. Named Spea labreae, the Ice Age spadefoot toad is an exceptionally rare find—only one other extinct Pleistocene amphibian has ever been identified in North America. Its bones had been sitting in collections since the 1950s before a researcher noticed features that set it apart from known species.

A black hole shredded a “super sun” — but something strange may have survived

Astronomers have witnessed a black hole violently shredding a massive star, creating one of the most energetic stellar explosions ever observed. The event, nicknamed “the Whippet,” briefly released about 400 billion times the Sun’s energy and sent a shock wave racing outward at one-fifth the speed of light. Months later, scientists spotted unexpectedly fast-moving helium, suggesting that some structure may have survived the destruction.

COVID-19 awakens dormant viruses — and one is linked to long COVID

COVID-19 can reactivate dormant viruses hiding in the body, including Epstein-Barr, cytomegalovirus, and several herpes viruses. One poorly understood viral family was strongly associated with long COVID and lasting disability, offering a potentially important clue to why some patients struggle to recover.

Scientists detect a surprising shift in human blood as CO2 rises

Rising carbon dioxide in the atmosphere may be leaving a measurable imprint inside the human body. Researchers analyzing more than two decades of U.S. health data found that blood bicarbonate levels have climbed about 7% since 1999, while calcium and phosphorus have declined—changes that closely track increasing atmospheric CO2.

When gut microbes run low on fiber, they may start eating you

Gut microbes need something to eat, and when fiber is limited, they may begin consuming proteins from the mucus lining that protects the gut. Researchers found that fiber can suppress this process, while indigestible plant proteins help microbes produce more beneficial compounds.

A 30-year-old fossil was hiding bones from a mysterious ancient sea monster

Fossils collected in Osaka more than 30 years ago have revealed a surprise hiding in plain sight: four previously unrecognized bones from a giant Cretaceous mosasaur. Among them is the first confirmed premaxilla—the frontmost bone of the upper jaw—ever identified in a Japanese mosasaur fossil. Even more intriguing, parts of the skull show unusual anatomical features that don’t match known mosasaurs, raising the possibility that the remains belong to an entirely new species.

Scientists solve the mystery of a brain “switch” that can trigger weight loss in opposite ways

Scientists have uncovered why two seemingly opposite ways of targeting the same brain receptor can both promote weight loss. In mice, activating the GIP receptor in the brainstem reduced appetite, while blocking it in the hypothalamus removed a kind of “brake” on fullness signals. The discovery helps explain why very different obesity drugs can achieve similar results and suggests that carefully combining GIP-targeting treatments with GLP-1 drugs like those related to Wegovy and Ozempic could pr
