ADHD stimulants appear to work less by sharpening focus and more by waking up the brain. Brain scans revealed that these medications activate reward and alertness systems, helping children stay interested in tasks they would normally avoid. The drugs even reversed brain patterns linked to sleep deprivation. Researchers say this could complicate ADHD diagnoses if poor sleep is the real underlying problem.

One psychiatrist has already treated 12 patients hospitalized with AI-induced psychosis â and three more in an outpatient clinic, according to the Wall Street Journal. And while AI technology might not introduce the delusion, "the person tells the computer it's their reality and the computer accepts it as truth and reflects it back," says Keith Sakata, a psychiatrist at the University of California, calling the AI chatbots "complicit in cycling...

Yesterday, the ground shook off the coast of Taiwan, slamming the country with the strongest earthquake in 27 years. The seismic wave registered 7.0 in Taiwan's scales, or 6.6 to 6.7 according to the USGS standard. Thankfully, according to reports, TSMC's factories are all intact, saving the world from yet another spike in chip prices. Read more âș

Tramadol, a popular opioid often seen as a âsaferâ painkiller, may not live up to its reputation. A large analysis of clinical trials found that while it does reduce chronic pain, the relief is modestâso small that many patients likely wouldnât notice much real-world benefit. At the same time, tramadol was linked to a significantly higher risk of serious side effects, especially heart-related problems like chest pain and heart failure,... Read more âș

Alzheimerâs has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brainâs energy supply help drive the diseaseâand restoring that balance can reverse damage, even in advanced cases. In mouse models, treatment repaired brain pathology, restored cognitive function, and normalized Alzheimerâs biomarkers. The results offer fresh hope that recovery may be possible. Read more âș

UBC Okanagan researchers have uncovered how plants create mitraphylline, a rare natural compound linked to anti-cancer effects. By identifying two key enzymes that shape and twist molecules into their final form, the team solved a puzzle that had stumped scientists for years. The discovery could make it far easier to produce mitraphylline and related compounds sustainably. It also highlights plants as master chemists with untapped medical potential. Read more âș

A new eco-friendly technology can capture and destroy PFAS, the dangerous âforever chemicalsâ found worldwide in water. The material works hundreds to thousands of times faster and more efficiently than current filters, even in river water, tap water, and wastewater. After trapping the chemicals, the system safely breaks them down and refreshes itself for reuse. Itâs a rare one-two punch against pollution: fast cleanup and sustainable destruction. Read more âș

The familiar fight between âmind as softwareâ and âmind as biologyâ may be a false choice. This work proposes biological computationalism: the idea that brains compute, but not in the abstract, symbol-shuffling way we usually imagine. Instead, computation is inseparable from the brainâs physical structure, energy constraints, and continuous dynamics. That reframes consciousness as something that emerges from a special kind of computing matter, not from running the right program. Read more âș

New research suggests Alzheimerâs may start far earlier than previously thought, driven by a hidden toxic protein in the brain. Scientists found that an experimental drug, NU-9, blocks this early damage in mice and reduces inflammation linked to disease progression. The treatment was given before symptoms appeared, targeting the disease at its earliest stage. Researchers say this approach could reshape how Alzheimerâs is prevented and treated. Read more âș

Scientists discovered that common food emulsifiers consumed by mother mice altered their offspringâs gut microbiome from the very first weeks of life. These changes interfered with normal immune system training, leading to long-term inflammation. As adults, the offspring were more vulnerable to gut disorders and obesity. The findings suggest that food additives may have hidden, lasting effects beyond those who consume them directly. Read more âș

Deep ocean hot spots packed with heat are making the strongest hurricanes and typhoons more likelyâand more dangerous. These regions, especially near the Philippines and the Caribbean, are expanding as climate change warms ocean waters far below the surface. As a result, storms powerful enough to exceed Category 5 are appearing more often, with over half occurring in just the past decade. Researchers say recognizing a new âCategory 6â could...

A shiny gray crystal called platinum-bismuth-two hides an electronic world unlike anything scientists have seen before. Researchers discovered that only the crystalâs outer surfaces become superconductingâallowing electrons to flow with zero resistanceâwhile the interior remains ordinary metal. Even stranger, the electrons on the surface pair up in a highly unusual pattern that breaks all known rules of superconductivity. Read more âș

A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation and starving brain tissue. When the missing molecule was restored, normal blood flow returned. This discovery opens the door to new treatments aimed at fixing vascular problems in dementia. Read more âș
