A global shift toward healthier diets could sharply reduce livestock farming, free up agricultural land, and cut emissions from land-use change by 85% by 2050。 At the same time, fruit, vegetable, nut, and legume production could soar, creating a sweeping transformation of what the world grows and eats
Sometimes, compelling stories beat medical evidence

As social media companies face scrutiny over addictive design features, mental health experts cite a stream of breakup content as an example of the failure to protect users
A svelte smart ring can track important activity, sleep, and health metrics。 Plus, unlike most smartwatches, it doesn’t need to be charged every day
Starlink has a Texas factory but also makes routers in Vietnam
Dying Sun-like stars may not fade away quietly。 As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction。 Thousands of these random kicks could eventually break apart distant stellar pairs or, in rare cases, drive two stars into a violent collision
Researchers are applying evolutionary theory to cancer by changing treatments before tumors have time to develop resistance。 Mathematical models suggest that rapid, carefully timed switches between multiple therapies could improve cure rates
A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics。 Using a quantum gravity framework called Gravity from Entropy, mathematician Ginestra Bianconi found that the Universe’s total entropy may rise as space expands, even while entropy within each unit of
Framework's latest modular laptop trades one set of problems for another
The US is making measles great again, so treatment options are needed for the most vulnerable
Scientists have uncovered new evidence that Venus may still be tearing itself apart from within。 Advanced 3D simulations indicate that some of the planet's giant rift valleys formed relatively recently and could still be expanding。 The results suggest Venus has a far more active interior than researchers once believed, challenging the long-held vie
Researchers discovered a proton-assisted mechanism that greatly improves how triplet energy moves between quantum dots and nearby molecules。 The proton briefly shifts position, helps coordinate electron movement, and then returns to where it started。 This quantum-driven shuttle could offer a powerful new way to tune solar cells, lasers, and catalyt
Google's and Reddit's use of DMCA to fight web scraper is bizarre, expert says
Telecom expects AI revenue from dark fiber deals and retrofitted data centers
Meme generator may have screwed up by using templates in outputs, expert says
NASA has not made substantial investments in thermal protection research for decades
A distant Sun-like star appears to have devoured one of its planets, leaving behind a surprising chemical fingerprint。 Researchers found an unusually high concentration of lithium, a strong sign that planetary material was mixed into the star。 Careful comparisons with dozens of similar stars confirmed the signal is highly unusual, and scientists th
NASA’s Swift Observatory observed a supermassive black hole ripping apart a star more than 30,000 light-years from the center of a distant galaxy。 The extraordinary flare briefly outshone its entire host galaxy in ultraviolet light and revealed a black hole about a million times the Sun’s mass
