Physicists have solved a long-standing problem involving systems that appear to violate Newton’s third law, such as bird flocks and bacterial swarms。 By adding carefully designed “imaginary partners” to their models, they can now simulate these complex systems with unprecedented accuracy
A recent episode underscored the Trump administration’s increasing reliance on advanced A。 systems for cybersecurity even as it battles a leading U
The purpose of Starfall is to support the "transport and delivery of goods through space
A new study from Northern Arizona University is raising red flags about a widely used global emissions database from Climate TRACE, a consortium co-founded by Al Gore。 Researchers found that the database may be dramatically undercounting carbon dioxide emissions from cars and trucks in cities—by an average of 70% across 260 U。 cities, with some cit
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
Yeti coolers are very nice and very expensive。 Three very different models are on sale right now
“I deleted it as a test and it came immediately back,” says one government employee
Researchers gave top AI models a classic attention test used in psychology and found a major flaw。 While the models could correctly name colors in short lists, their performance deteriorated sharply as the task became longer and more complex。 Some leading systems fell from over 90% accuracy to nearly complete failure
We built HALO (Hierarchal Agent Loop Optimizer), an open-source tool for debugging and optimizing AI agents using their execution traces。It’s a loop。 Run your agent, feed the traces to HALO, get the report, apply the fixes, then re-run your agent
TikZ is a widely-used LaTeX package for drawing figures in papers。 It uses commands like \draw[->] (0,0) -- (1,2); to draw lines, shapes, text, etc。 Academics usually code up their figures by hand, so there is lots of twiddling around with the coordinates and recompiling until things look nice
Scientists have digitally preserved the world’s most endangered marine mammal by creating highly detailed 3D models of a vaquita skeleton using advanced imaging technology。 The virtual archive provides an unprecedented look at the species and could help inspire conservation efforts before the tiny porpoise disappears forever
Federal officials are urging the lone major tech company holdout to allow government safety evaluations, weeks after ordering Anthropic to pull its latest model
A newly identified molecule called OLE helped restore the brain’s immune cells to a more protective state in Alzheimer’s models。 The treatment reduced toxic plaque buildup and improved memory, raising hopes for a new therapeutic approach
Researchers uncovered why H5N1 bird flu attacks cows’ udders instead of their lungs: the virus’s preferred receptors are concentrated in mammary tissue。 The breakthrough could help scientists predict future bird flu jumps and spot unusual infections before they spread widely
June's night sky delivers several must-see events, starting with a close encounter between Venus and Jupiter after sunset。 Mercury joins the pair to form a rare three-planet lineup, while the Moon puts on a special show by passing in front of Venus for viewers in parts of the Americas。 The month also marks the start of astronomical summer and the r
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
Workers at the artificial intelligence company have been puzzled and increasingly concerned by the administration’s move to limit their latest A
