Scientists have developed a new multi-layered metalens design that could revolutionize portable optics in devices like phones, drones, and satellites. By stacking metamaterial layers instead of relying on a single one, the team overcame fundamental limits in focusing multiple wavelengths of light. Their algorithm-driven approach produced intricate nanostructures shaped like clovers, propellers, and squares, enabling improved performance, scalability, and polarization independence.

You can make your RTX 5090 just a teeny bit more powerful and less efficient, thanks to a new 800W BIOS stripped from Asus' $4000 ROG Matrix RTX 5090. As long as you have a compatible 5090 that'll play nicely with the custom firmware, you, too, can enjoy higher clocks and electricity bills for a marginal increase in performance. Read more ›

Wireless charging has become one of those small but satisfying conveniences of modern smartphones. You drop your device on a pad and watch the battery percentage climb without fiddling with cables or ports. Yet for many users, that effortless charge doesn’t always come at the speed they expect. Sometimes the phone warms up, the percentage barely rises or charging takes far longer than it would if you plugged it in.... Read more ›

Researchers found that tau proteins don’t jump straight into forming Alzheimer’s-associated fibrils—first they assemble into soft, reversible clusters. When the clusters were dissolved, fibril growth was almost entirely suppressed. This reveals a promising new strategy: stop the precursors, stop the disease. Read more ›

Rutgers scientists found that metformin can blunt many of the metabolic and cardiovascular improvements normally produced by exercise. Participants who took the drug saw reduced gains in fitness, blood vessel function, and glucose control. The interference may stem from how metformin affects mitochondrial activity. Read more ›

Chronic kidney disease has surged to nearly 800 million cases and is now among the top causes of death worldwide. The condition is heavily linked to diabetes, hypertension, and obesity, and often goes unnoticed until late stages. Many countries lack access to dialysis and transplants, leaving millions without adequate care. Read more ›

Electrons can freeze into strange geometric crystals and then melt back into liquid-like motion under the right quantum conditions. Researchers identified how to tune these transitions and even discovered a bizarre “pinball” state where some electrons stay locked in place while others dart around freely. Their simulations help explain how these phases form and how they might be harnessed for advanced quantum technologies. Read more ›

Scientists discovered that alcohol activates a sugar-producing pathway in the body, creating fructose that may reinforce addictive drinking. The enzyme responsible, KHK, appears to drive both alcohol cravings and liver injury. When this enzyme was blocked in mice, their drinking decreased and their livers showed far less damage.

Scientists found that people who use both cannabis and tobacco show a distinct brain pattern tied to mood and stress regulation. Their scans revealed higher levels of an enzyme that reduces a natural feel-good molecule in the brain. This imbalance may help explain why co-users experience more anxiety and struggle more when quitting. Read more ›

People are more likely to believe lies when there’s the possibility of a reward. Neuroimaging shows that the brain shifts into reward or risk mode depending on whether the context involves a gain or a loss. Friends show synchronized brain activity that can predict successful deception. Social bonds and incentives can subtly warp how we judge honesty. Read more ›

Ultra-processed foods, already known for their links to health problems in adults, are now shown to harm young adults too, disrupting blood sugar regulation long before illness appears. A four-year USC study following 85 participants found that even modest increases in UPF consumption drove up the risk of prediabetes and insulin resistance, two early markers that pave the way for type 2 diabetes.
