Thawing Arctic permafrost is releasing ancient carbon into the ocean, raising fears that microbes could turn it into greenhouse gases and accelerate climate change。 But sediment cores collected near Canada’s Herschel Island reveal a more reassuring twist: most of this land-based carbon becomes buried in the seafloor, while only about 10 percent is
Taiwan’s steep, remote mountains have sheltered extraordinary forests containing hundreds of giant Taiwania firs。 After years of difficult expeditions, LiDAR mapping, and citizen-science detective work, researchers discovered an 84。1-meter (276-foot) tree, the tallest known in East Asia
Dark matter particles may exert a hidden force on one another, but its effects are stranger than expected。 An extra attraction helps the particles cluster, yet it also makes dark matter effectively lighter as the Universe expands。 That weakens its gravitational impact and usually slows the growth of cosmic structure rather than accelerating it

Mathematicians have shown that no electoral system can perfectly balance local representation, proportional national results, and a fixed-size parliament once enough parties compete。 A newly proposed voting method could soften these unavoidable trade-offs and produce outcomes that are much closer to fair

Researchers have found a way to build much larger “twisted” oxide materials while precisely controlling how their atomic layers line up。 Because these materials can be made over large areas and transferred onto different surfaces, the technique could help turn twistronics from a laboratory curiosity into a practical platform for next-generation ele
Billions of dollars are being poured into a new wave of AI technology。 But will it pay off
Clement Delangue said he didn't want cyber attacks on other companies to become "normalised"
The Trump administration has struggled over how to approach to “open source” models, which are freely available to download and favored by Chinese companies
A Louisiana launch site would offer several significant advantages
The solar wind may be stripping away Mars’ atmosphere by creating giant rolling waves along its outer edge。 Data from MAVEN and Tianwen-1 show that these waves form plasma clouds that carry atmospheric particles into space。 The process is concentrated on one side of Mars and may have played a major role in drying out the once potentially habitable
Over the years, tech workers have proudly worn nerdy company-branded gear。 But this generation of hot companies is getting fancy with its merch
When atomic nuclei smash together at nearly the speed of light, they create the hottest fluid in the universe, but scientists may have overlooked one of its most important forces。 New simulations reveal that extreme acceleration builds up along the edges of quark-gluon plasma, helping drive its explosive expansion。 This acceleration may do far more

Hidden moon ice may reveal itself through the way it bends and reflects vibrations from moonquakes。 The technique could help astronauts locate vital water supplies and uncover clues about the origins of Earth’s oceans
A new Google Earth tool allowed the creation of A。 deepfake maps。 The company quickly pulled it back after users noted there were no safeguards to prevent content that could be harmful
