Harvard scientists have uncovered that lithium, a naturally occurring element in the brain, may be the missing piece in understanding Alzheimer’s. Their decade-long research shows that lithium depletion—caused by amyloid plaques binding to it—triggers early brain changes that lead to memory loss. By testing new lithium compounds that evade plaque capture, they reversed Alzheimer’s-like damage and restored memory in mice at doses far lower than those used in psychiatric treatments.

A July combat training exercise involved a satellite dish-style antenna that "could fire enough electromagnetic energy to fry the satellite 22,000 miles away," reports the Washington Post. But "Instead, the salvo would be more covert — millisecond pulses of energy that would subtly disrupt the satellite's signals, which U.S. military forces were using to communicate in the Pacific Ocean." The goal was to disguise the strike as a garbled connection... Read more ›

A new hypercar has dethroned Bugatti's record for the fastest production car, and unsurprisingly, it's an electric vehicle. During a livestream at the Automotive Testing Papenburg testing site in Germany, the YangWang U9 Extreme hit a facemelting top speed of 496.22 kmph, or around 308.33 mph. That metric edges out the previous record from the Bugatti Chiron Super Sport 300+, which achieved 304.77 mph in 2019. Officially, the fastest production... Read more ›

An AI-generated image posted by President Trump depicts him buying Intel stock at $20 and selling it at $30 to make a considerable profit. These prices are mostly accurate, given that the real-life purchase occurred at $20.47 per share, and Intel stock reached over $30 just two days ago, although that rise can be attributed to the Nvidia deal instead.

Scientists in Zurich have shown that stem cell transplants can reverse stroke damage by regenerating neurons, restoring motor functions, and even repairing blood vessels. The breakthrough not only healed mice with stroke-related impairments but also suggested that treatments could soon be adapted for humans, marking a hopeful step toward tackling one of the world’s most devastating conditions.

New research from Denmark challenges long-held assumptions about body weight and health, revealing that being overweight—or even moderately obese—does not necessarily increase the risk of death compared to those at the upper end of the "normal" BMI range. In fact, those who are underweight or at the lower end of the so-called healthy spectrum faced higher risks. Read more ›

Warming Arctic permafrost is unlocking toxic metals, turning Alaska’s once-clear rivers into orange, acid-laced streams. The shift, eerily similar to mine pollution but entirely natural, threatens fish, ecosystems, and communities that depend on them—with no way to stop the process once it starts. Read more ›

Nitazenes, a powerful and largely hidden class of synthetic opioids, are quickly becoming a deadly factor in the overdose crisis. Over 20 times stronger than fentanyl, these drugs often go undetected on routine drug tests, making overdoses harder to diagnose and reverse. Cases from Tennessee reveal a disturbing pattern of fatalities, with nitazenes frequently mixed into counterfeit pills alongside fentanyl and methamphetamine. Read more ›

Scientists at Harvard have discovered how salts like lithium bromide break down tough proteins such as keratin—not by attacking the proteins directly, but by altering the surrounding water structure. This breakthrough opens the door to a cleaner, more sustainable way to recycle wool, feathers, and hair into valuable materials, potentially replacing plastics and fueling new industries. Read more ›

Microplastics have been detected in human blood, brain tissue, and even bones, where they may weaken skeletal structure and accelerate cell aging. Recent studies suggest that these particles could worsen metabolic bone diseases like osteoporosis, a risk that’s especially concerning as fractures are projected to rise sharply in the coming decades.

Dry eyes are far more common than previously believed, with over half of adults in the US and Europe experiencing symptoms, yet most remain undiagnosed for years. The large-scale NESTS study reveals that sufferers often endure daily discomfort that disrupts work, driving, and even surgery outcomes. Many accept the condition as part of aging, unaware that simple treatments could provide relief. Read more ›

Despite strong evidence that salt substitutes can safely lower sodium intake and reduce high blood pressure, very few Americans use them. A new analysis of nearly 20 years of national health data found that usage peaked at just over 5% and then declined, even among those with hypertension. Researchers say this represents a major missed opportunity to improve heart health, especially since salt substitutes are inexpensive and effective. Read more ›
