Popular joint supplement glucosamine linked to faster Alzheimer’s progression

A major study suggests glucosamine, a popular supplement for joint pain, could be linked to faster progression from mild cognitive impairment to Alzheimer’s disease. Researchers found a 25% higher likelihood of developing dementia among glucosamine users and uncovered biological clues that may explain why.

Earth's first animals barely evolved until sex changed everything

Earth’s earliest animals may have held evolution back because they reproduced asexually, creating low-competition communities that changed very little over time. When environmental pressures pushed them toward sexual reproduction, biodiversity exploded and evolution accelerated dramatically.

Cancer patients found a simple way to stay mentally sharp during chemotherapy

“Chemo brain” affects up to 80% of people receiving chemotherapy, making everyday tasks harder. In a new trial, cancer patients who followed a home-based exercise program showed better attention and fewer noticeable cognitive problems than those who received a placebo. Low-dose ibuprofen also improved some cognitive measures, though its effects were less consistent.

NASA Knows: What Is Mass Distribution?

This article is for students grades 5-8. Mass distribution affects everything from galaxy shapes to aircraft design to planetary rotation. It’s used to map stars in our universe, figure out what planets are made of, and even to determine how luggage is loaded onto an airplane. Mass distribution can be a tricky thing to understand. […]

Ultra-processed foods may be stealing your focus even if you eat healthy

A study of more than 2,100 adults found that eating more ultra-processed foods was linked to poorer attention and slower mental processing, even among people with otherwise healthy diets. Researchers also found higher consumption was associated with increased dementia risk factors, raising concerns about the hidden cognitive costs of heavily processed foods.

Sleep apnea’s hidden heart disease trigger found in the gut

A surprising gut-heart connection may help explain why sleep apnea increases the risk of cardiovascular disease. In mice, disabling a bile acid receptor called FXR sharply reduced plaque buildup, opening the door to potential new treatments based on gut microbes and their chemical signals.

Scientists think they solved the mystery of the Amaterasu particle

The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better able to retain their energy while traveling through space. This idea could help explain how these rare particles reach Earth and provide new clues about the powerful cosmic explosions that create them.

The species is abundant within the protected archipelago but when they migrate outside the marine reserve to give birth they run the gauntlet of industrial fishingThe unmistakable fluted T-shape of a scalloped hammerhead shark slides by, followed by a diver holding his breath and a metal spear like an extra-long snooker cue.

An invisible forever chemical rain is falling across the planet

A surprising study suggests that chemicals introduced to protect the ozone layer may have unintentionally created a growing global pollution problem. Researchers found that refrigerants and certain anesthetic gases have generated more than 335,000 tonnes of trifluoroacetic acid (TFA), a highly persistent "forever chemical," that has been deposited across Earth's surface since 2000. The pollutant is now showing up everywhere from rainwater to remote Arctic ice, and scientists expect levels to kee

The secret reason some cancer treatments stop working

Scientists have uncovered a hidden immune system "brake" that may help cancers avoid being destroyed. The molecule, called SLAMF6, weakens the body's cancer-fighting T cells and can leave them exhausted over time. Researchers developed antibodies that block this brake, allowing immune cells to stay stronger and attack tumors more effectively in mice.

World's largest opioid review finds they often don't work

The largest review ever conducted on opioids for acute pain found that these widely prescribed drugs often deliver only small, short-lived benefits. For many common conditions, including some surgeries and kidney stone pain, opioids performed no better than a placebo. Researchers also found higher rates of side effects and warned that dependence can begin after only a short period of use.
