New research suggests the astringent sensation caused by flavanols could act as a direct signal to the brain, triggering effects similar to a mild workout for the nervous system. In mouse experiments, flavanol intake boosted activity, curiosity, learning, and memory—despite these compounds barely entering the bloodstream. The key appears to be sensory stimulation: the taste itself activates brain pathways linked to attention, motivation, and stress response, lighting up regions involved in arousal and memor

Last Sunday, Bitcoin had dropped 13% in three days, to $76,790. By Thursday it had dropped another 21%, to $60,062. This morning it's at $69,549 — up from Thursday, down from Sunday, but 44% lower than its all-time high in October of $123,742. In short, Bitcoin "is down almost 30% this week alone," reports CNBC: "This steady selling in our view signals that traditional investors are losing interest, and overall... Read more ›

Trump Mobile is already failing to deliver on some early promises, according to the latest report from The Verge. The report revealed the near-final design of the T1 smartphone and uncovered some major changes with pricing and manufacturing. The Verge spoke with Don Hendrickson and Eric Thomas, two of the three execs behind Trump Mobile, about the company's first smartphone, which will get a more expensive price tag and no... Read more ›

It's a complete coincidence that I installed Linux around the same time as my colleagues Nathan Edwards and Stevie Bonifield. A few months ago, I decided to breathe new life into a 2019 Dell XPS 15 that had been collecting dust for a couple of years. Despite its (at the time) high-end Core i7 CPU […] Read more ›

I'm an awful rock climber. Being scared of heights probably doesn't help. But when I've tried it, I've loved the slow, methodical work of moving from one ledge to the next. It reminds me a lot of why I love running; in both sports, you achieve goals that seem insurmountable by taking them one step […] Read more ›

Somewhere on America's eastern coast, there's an economic development agency in Massachusetts promoting green energy solutions. And Monday the Massachusetts Clean Energy Center (or MassCEC) announced "a first-of-its-kind" program to see what happens when they provide free electric vehicle chargers to selected residents, school districts, and municipal projects. The catch? The EV chargers are bi-directional, able "to both draw power from and return power to the grid..." The program hopes... Read more ›

A massive Swedish study tracking nearly 28,000 people for 25 years found an unexpected link between full-fat dairy and brain health. Among adults without a genetic risk for Alzheimer’s, eating more full-fat cheese was associated with a noticeably lower risk of developing the disease, while higher cream intake was tied to reduced dementia risk overall. The findings challenge decades of low-fat dietary advice but come with important caveats. Read more ›

Researchers have discovered a hidden quantum geometry inside materials that subtly steers electrons, echoing how gravity warps light in space. Once thought to exist only on paper, this effect has now been observed experimentally in a popular quantum material. The finding reveals a new way to understand and control how materials conduct electricity and interact with light. It could help power future ultra-fast electronics and quantum technologies.

Scientists at Keck Medicine of USC are testing an experimental stem cell therapy that aims to restore the brain’s ability to produce dopamine, the chemical whose loss drives Parkinson’s disease. The early-stage clinical trial involves implanting lab-grown dopamine-producing cells directly into a key movement-control region of the brain, with the hope of slowing disease progression and improving motor function.

Even in some of the most isolated corners of the Pacific, plastic pollution has quietly worked its way into the food web. A large analysis of fish caught around Fiji, Tonga, Tuvalu, and Vanuatu found that roughly one in three contained microplastics, with Fiji standing out for especially high contamination. Reef and bottom-dwelling fish were most affected, linking exposure to where fish live and how they feed. Read more ›

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing many qubits to be read at once. The team has already demonstrated working arrays with dozens and even hundreds of cavities. The approach could eventually support massive quantum networks with millions of qubits. Read more ›

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus-control problem in light-shaping materials. This opens the door to tiny, highly efficient light sources integrated directly onto chips.

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of years. Using ancient magnetic records and advanced simulations, scientists discovered that these formations influence the movement of liquid iron in Earth’s core. Some parts of the magnetic field remained stable over vast stretches of time, while others changed dramatically. Read more ›

Middle age is becoming a tougher chapter for many Americans, especially those born in the 1960s and early 1970s. Compared with earlier generations, they report more loneliness and depression, along with weaker physical strength and declining memory. These troubling trends stand out internationally, as similar declines are largely absent in other wealthy nations, particularly in Nordic Europe, where midlife well-being has improved. Read more ›

A new imaging breakthrough combines ultrasound and light-based techniques to generate vivid 3D images that show both tissue structure and blood vessel activity. Developed by researchers at Caltech and USC, the system delivers detailed results quickly and without radiation or contrast dyes. It has already been used to image multiple parts of the human body. The approach could significantly improve cancer detection, nerve-damage monitoring, and brain imaging. Read more ›

Scientists are digging into why heart disease risk in type 2 diabetes differs between men and women—and sex hormones may be part of the story. In a large Johns Hopkins study, men with higher testosterone had lower heart disease risk, while rising estradiol levels were linked to higher risk. These hormone effects were not seen in women. The results point toward more personalized approaches to heart disease prevention in diabetes. Read more ›
