A tiny set of ancient genetic “switches” may have played a surprisingly large role in making human language possible。 Researchers found that these DNA regions, which act like volume controls for genes involved in brain development, have an outsized influence on language ability despite making up less than 0。1% of the genome
Deep beneath the ground in China, the massive JUNO neutrino observatory has delivered its first major scientific breakthrough, achieving one of the most precise measurements yet of how elusive neutrinos change as they travel。 Using just 59 days of data, researchers sharply improved measurements of key neutrino properties, boosting confidence that J
Scientists at the University of Hong Kong have created a remarkable new type of brain-inspired chip that can function just above absolute zero, one of the coldest environments imaginable。 By using a standard silicon carbide transistor in a completely new way, the team made a single device behave like an energy-efficient neuron, firing electrical “s
Scientists have developed an artificial photosynthesis system that essentially regulates itself, eliminating the need for batteries used in many current designs。 The key innovation is an electrolyzer that automatically adapts to changing sunlight by altering its electrical properties as it heats up。 This keeps solar fuel production more stable whil
A new nature-inspired membrane uses perfectly uniform one-nanometer pores to filter molecules with remarkable precision。 The technology could transform industries such as pharmaceuticals and textiles by reducing energy consumption, improving water reuse, and delivering separation performance far beyond current filters
Scientists found that transfer learning can make the search for new physics in the universe much faster, slashing the need for expensive simulations。 Yet the approach can backfire when AI relies too heavily on familiar patterns, potentially missing evidence of something truly new
A spectacular fossil fish discovered on a remote cliff in New Zealand nearly 30 years ago has finally revealed its full story thanks to an unexpected discovery: the original collector’s long-lost field notebooks。2-meter fossil, preserved in stunning three-dimensional detail, belonged to an ancient tarpon-like predator that cruised New Zealand water
FIFA announced agreements with platforms such as TikTok and YouTube that include the participation of dozens of international influencers to generate content in the three host countries
At The New York Times’s Hard Fork Live event, Mr。 Nadella addressed the backlash against artificial intelligence and President Trump’s comments about Americans sharing in the wealth of A
Scientists discovered that rice behaves in a highly unusual way: it weakens under rapid compression but stays stronger when pressure is applied slowly。 Using this effect, they engineered a new material that reacts differently to gentle movements and sudden impacts。 The material can adapt its stiffness automatically, opening the door to safer soft r
Researchers in South Korea have recreated the legendary “sea silk” once prized by emperors, using fibers from a clam cultivated in Korean coastal waters。 They discovered that its famous golden shine comes from tiny protein structures that reflect light rather than from pigments or dyes。 Because the color is built into the fiber’s structure, it can
