Sunlight creates quantum entanglement once thought to require lasers
1+ hour, 8+ min ago (52+ words) Scientists have generated quantum entanglement directly from sunlight, potentially offering a lower-energy alternative to the lasers normally used in quantum technology. Their outdoor experiment produced entangled photons with about 94% similarity to an ideal state. The result could pave the way…...
Teen cannabis use linked to slower memory and thinking growth
3+ hour, 32+ min ago (415+ words) Tracking Cannabis Use and Cognitive Growth The research team followed 11,036 children from ages 9 to 10 through ages 16 and 17. During that period, the scientists monitored changes in cognitive performance as well as the participants' use of cannabis and other substances. To measure…...
Vitamin C may fight cancer — but not the way scientists once thought
15+ hour, 55+ min ago (673+ words) Half a century on, the story looks more complicated. Pauling was wrong in important ways, but he was not entirely wrong. Modern research is giving vitamin C a second look in cancer, and it turns out that under certain conditions…...
UCLA scientists discover how to guide heat like light at room temperature
16+ hour, 35+ min ago (315+ words) Scientists have demonstrated that heat can move through a crystal in focused, wave-like rays at room temperature instead of spreading randomly. The breakthrough could make it possible to route heat around sensitive parts of next-generation chips and quantum devices....
The key to colonizing Mars may be hidden inside asteroids
23+ hour, 28+ min ago (367+ words) Metal-rich asteroids could one day become hardware stores for Mars, supplying the materials needed to build and repair a growing colony. A new analysis shows that carefully selected asteroids may be reachable with current spacecraft technology. Some could even provide…...
Scientists find unexpected life on Ötzi the Iceman’s 5,300-year-old body
1+ day, 33+ min ago (443+ words) More than 5,000 years after his death, Ötzi the Iceman is still hosting a remarkable mix of ancient and modern microorganisms. Researchers separated microbes that lived in his body during his lifetime from those that arrived after his death, uncovering traces…...

Scientists discover a hidden brain shift that begins around age 50
1+ day, 3+ hour ago (292+ words) Beginning around age 50, the brain’s memory center appears to lose many of its longtime immune cells and replace them with more inflammatory ones. This surprising shift may help explain how normal aging sets the stage for Alzheimer’s disease and dementia....
A star’s violent death exposed a hidden supermassive black hole
1+ day, 16+ hour ago (706+ words) A supermassive black hole has been found lurking about 30,000 light-years from the center of its galaxy—the first dormant black hole detected so far from a galactic core. It revealed itself only after shredding a passing star and producing a…...
Cell-inspired nanoreactor turns sunlight into hydrogen peroxide
1+ day, 16+ hour ago (320+ words) Researchers have created a hollow CdS@polydopamine nanoreactor that imitates two important features of living cells. The design offers a new way to reproduce some of the highly organized chemical functions of cells inside synthetic nanomaterials. The findings were published…...
