Scientists at UC Santa Barbara have created a remarkable new material that works like a “rechargeable solar battery,” storing sunlight inside tiny molecules and releasing it later as heat — even long after the sun goes down。 Inspired by reversible changes found in DNA and photochromic sunglasses, the system captures solar energy without relying on
As blood stem cells age, their lysosomes become overactive and damaged, triggering inflammation and weakening the body’s ability to regenerate healthy blood and immune cells。 By calming this cellular “overdrive,” researchers restored the stem cells’ youthful function, dramatically boosting their ability to regenerate and produce balanced blood cell
Scientists have uncovered a surprising secret hidden inside fat cells that could reshape how we think about obesity and metabolic disease。 A protein called HSL, long believed to simply release stored fat when the body needs energy, turns out to have a second job deep inside the nucleus of fat cells—helping keep those cells healthy and balanced。 Eve
NASA’s Curiosity rover had an unexpectedly stubborn Mars souvenir after drilling into a rock nicknamed “Atacama” — the entire chunk ripped loose from the ground and stayed stuck to the rover’s drill。 Engineers watched as Curiosity shook, vibrated, tilted, and spun the drill over several days in an effort to free the rock, while cameras captured the
Astronomers using the James Webb Space Telescope have spotted something that shouldn’t exist—at least not so early in the universe。 A massive galaxy, formed less than 2 billion years after the Big Bang, appears to have no rotation at all, a trait usually seen only in much older, evolved galaxies。 This challenges current theories that young galaxies
Penn researchers have developed a smarter AI method for solving notoriously difficult inverse equations, which help scientists uncover hidden causes behind observable effects。 By introducing “mollifier layers” that smooth noisy data, they’ve made these calculations more stable and far less computationally demanding。 This could transform fields like
Scientists may have found a powerful new way to hunt for alien life — not by searching for specific molecules, but by looking for hidden patterns in how those molecules are organized。 Researchers discovered that living systems leave behind a kind of chemical “fingerprint” in the statistical distribution of amino acids and fatty acids, one that cons
A major obstacle may be standing in the way of the next generation of ultra-tiny computer chips。 Researchers discovered that many promising 2D materials lose their advantages because an invisible atomic-scale gap forms when they are combined with insulating layers。 That tiny gap weakens electronic performance and could prevent further miniaturizati
The little pauses, “ums,” and moments when you struggle to find the right word may reveal far more about your brain than anyone realized。 Researchers discovered that everyday speech patterns are closely tied to executive function — the mental system that powers memory, planning, focus, and flexible thinking。 By using AI to analyze natural conversat
It's not entirely clear how the exploit works。 Microsoft says it's investigating
Researchers in Japan traced a hidden medieval solar storm using ancient tree rings and centuries-old sky observations。 The team linked reports of eerie red auroras with spikes of carbon-14 trapped in buried wood, revealing a powerful solar radiation event around 1200 CE。 The findings suggest the Sun was far more active at the time, with unusually s
Ocean heat plus human-caused global warming is a grim recipe for deadly climate extremes
A new quantum-inspired algorithm has cracked a problem so massive that conventional supercomputers struggle to even approach it。 Researchers used the method to simulate extraordinarily complex quantum materials known as quasicrystals, opening the door to powerful new quantum devices and ultra-efficient electronics。 The work could help scientists de
A bizarre planetary pairing 190 light-years away is challenging everything astronomers thought they knew about how worlds form。 A “lonely” hot Jupiter — typically found without nearby companions — is sharing its system with a smaller mini-Neptune tucked even closer to the star, a setup once thought nearly impossible
The Universe’s biggest black holes may not be born giants after all。 Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes are likely “cosmic recyclers” — formed through repeated smashups inside incredibly crowded star clusters。 These violent chain reactions appear to creat
