Scientists have created the first quantum material that can sort and transport different quantum states of light at room temperature, potentially removing the need for bulky, ultra-cold refrigeration systems。 Built from a gold film carved with hundreds of microscopic structures, the ultrathin “metacrystal” acts like a filter that directs different

What was the thinking of the investors backing the now-canned plan, and are such proposals in the future inevitable

A few details from the White House’s A。 plan have leaked to the news media, but the administration has officially communicated almost nothing

With rising temperatures and drier conditions, fires are more likely to explode。 And with more people living next to forests, the results can be catastrophic

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 of his original gut bacteria and cold-loving yeasts that may have survived alongside him i

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

DOGE's inflated "Wall of Receipts": 96% of grant savings unverifiable, GAO says

A new wearable patch may help people reach REM sleep faster and remain there longer without medication or surgery。 In a study of 28 participants, the device shortened the time to REM by 43 minutes and extended it by about 16 minutes。 Researchers also observed signs of improved stress regulation and changes in brain circuits tied to emotion

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 brief, brilliant flare。 Astronomers think it may be the remnant of a devoured galaxy or a black hole flung o
