A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision。 The discovery suggests some early planets formed from dramatically different materials than Earth and Mars, rewriting part of the solar system’s origin story
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
The global cobalt supply chain is more interconnected—and more vulnerable—than previously thought, with disruptions capable of triggering far-reaching cascades across multiple countries and industries。 Researchers warn that protecting battery supply chains will require system-wide coordination because critical bottlenecks can turn local shocks into
Scientists at RIKEN have proposed a new way to make quantum systems synchronize in only one direction—like a one-way street for sound particles known as phonons。 The breakthrough combines two quantum effects to create a form of one-way quantum synchronization that remains surprisingly stable even when exposed to manufacturing flaws and environmenta
MIT researchers have shown that one fuel can power both chemical and electric spacecraft thrusters, potentially transforming what small satellites can do。 The approach combines quick bursts of speed with highly efficient long-range propulsion in a single compact system。 A NASA-supported CubeSat mission will soon test the technology in orbit
Scientists used nanoscale gold metamaterials to supercharge heat transfer across tiny gaps, achieving up to four times more energy flow than similar conventional systems。 The breakthrough could lead to better chip cooling, more efficient energy technologies, and a new era of precision heat engineering
A newly identified crocodile species nicknamed “Lucy’s hunter” prowled Ethiopia’s rivers when Lucy’s species walked the Earth more than 3 million years ago。 The giant predator was likely the most dangerous animal in the ecosystem and may have regularly hunted early human relatives
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
Millipedes may have been crawling across Earth's landscapes nearly 460 million years ago, long before vertebrates ventured onto land。 A new study finally completes their evolutionary family tree, revealing surprising clues about these ancient ecosystem engineers and their early chemical defenses
A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō。 The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife and driving extinctions long before humans arrived
A new study suggests Southern California's major fault system is more stressed than at any point in the last 1,000 years。 Researchers found that the Cajon Pass, where the San Andreas and San Jacinto faults meet, could act as an “earthquake gate” that determines whether a future rupture spreads across both faults。 Current conditions resemble those t
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
Researchers tracked honey bees in the wild using a drone-based system and found that each bee follows its own highly consistent flight path。 Some repeated their routes so precisely that they flew only centimeters from where they had flown before。 Landmarks like trees helped keep them on track, while uniform areas such as cornfields led to more vari
Researchers found that twisting layered sheets of hexagonal boron nitride can dramatically change the light produced by quantum emitters embedded within the material。 The technique offers an unexpected new level of control over components that could power future quantum computers, communications systems, and sensors
Oak is a version control system I've been working on designed for agents (https://oak。 It improves the speed and context your agents need when working on serious projects。 With virtual mounts, agents locally and in the cloud no longer need a full copy of a repo to get working
Freshwater lakes across North America and Europe are becoming noticeably browner, reducing underwater visibility and reshaping fish populations。 Research found that several popular sport fish, including trout, bass, perch, and whitefish, tend to decline in darker waters。 Meanwhile, walleye and northern pike often become more abundant because they a
