Scientists have identified new clues that could help astronomers spot one of the most famous hypothetical alien megastructures: a Dyson sphere。 The study finds that red dwarfs and white dwarfs are the most promising stars to examine, since advanced civilizations could potentially build energy-harvesting swarms around them more easily。 These objects

Researchers solved the mystery of how soft lithium dendrites crack the hard ceramic inside solid-state batteries, triggering short circuits。 The breakthrough could help engineers build safer, longer-lasting batteries for smartphones, electric vehicles, and other electronics

The hunt for ancient life on Mars just got an important test run。 Scientists confirmed that the Rosalind Franklin rover's sophisticated instrument can detect subtle differences in two stable molecules that could preserve evidence of past life for billions of years。 But the team also uncovered a surprise: organic molecules in the Murchison meteorite

A new quantum theory bridges two rival models of how impurities behave inside many-particle systems, resolving a problem that has challenged physicists for decades。 The findings could reshape experiments on ultracold atoms, semiconductors, and other exotic forms of quantum matter

The Times, The New York Daily News and other media organizations accused OpenAI of withholding evidence in a lawsuit

ive been seeing a recurring claim that open (weight) models 6 months behind the frontier are good enough for the majority of ‘work’。 if you've had a concrete task in the last month where GLM/DeepSeek/Kimi/Qwen failed and Opus/Fable/GPT succeeded (or vice versa。), please shareIll provide a template as ive also frequently seen posters complain about

These are the cleaning robots, water monitors, and toys actually worth buying for pool season

Solid-state batteries are safer and more capable—but harder to mass-produce。 They also represent an opportunity for non-Chinese companies to get back in the game

Yes, Sarah Wynn-Williams violated her deal to stay silent。 But the power disparity bolsters the view that Meta is a heartless bully

The ASA says adverts claiming small devices can rapidly cool rooms were too good to be true

Scientists have rewritten the story of gallium after discovering that its unusual atomic bonds re-form at high temperatures, contradicting decades of accepted theory。 The finding changes how researchers explain why the metal melts so easily and behaves unlike almost any other metal。 Beyond solving a long-standing scientific mystery, the work could

A surprising discovery is reshaping scientists' understanding of how humans develop sharp central vision before birth。 Instead of blue cone cells migrating away from the retina's center, the study found they transform into red and green cones under the influence of vitamin A-related signals and thyroid hormones。 The findings could improve lab-grown

A planet with one side permanently roasting and the other frozen in endless darkness might still have a chance of supporting life。 Researchers found that heat inside a tidally locked exoplanet could circulate in a stable, continuous loop, helping moderate temperatures in certain regions。 Their laboratory model suggests these worlds may be more hosp
