The Trump administration, which took a noninterventionist approach to artificial intelligence, is now discussing imposing oversight on A。 models before they are made publicly available
A group of undergraduate students pulled off something remarkable: they built their own dark matter detector and used it to probe one of physics’ biggest mysteries。 Working with limited resources but plenty of creativity, they designed a stripped-down experiment to hunt for axions — hypothetical particles that could make up dark matter
Oak trees have a surprising trick to fight back against hungry caterpillars: they simply wait。 When trees are heavily attacked one year, they delay leaf growth by just three days the next spring—long enough to leave newly hatched caterpillars with nothing to eat。 This small shift slashes insect survival and reduces leaf damage by more than half, pr
Evolution seems to follow a script more often than expected。 Researchers found that distantly related butterflies and moths have reused the same pair of genes for over 120 million years to produce strikingly similar warning colors。 Rather than altering the genes themselves, evolution modifies how they’re switched on and off
In 1990, three former Apple employees launched a company that epitomized the Silicon Valley dream。 What they invented looked like an iPhone—more than a decade earlier。 The device never came to be
For the first time, scientists have watched a subduction zone literally fall apart beneath the ocean floor。 Using advanced seismic imaging, they found the Juan de Fuca plate splitting into fragments as it sinks beneath North America。 Rather than collapsing all at once, the plate is tearing piece by piece, like a train slowly derailing
Penn researchers have developed a smarter AI method for solving notoriously difficult inverse equations, which help scientists uncover hidden causes behind observable effects。 By introducing “mollifier layers” that smooth noisy data, they’ve made these calculations more stable and far less computationally demanding。 This could transform fields like
Researchers have, for the first time, directly visualized how electronic patterns known as charge density waves evolve across a phase transition。 Using cutting-edge microscopy, they found these patterns form unevenly, breaking into patches influenced by tiny structural distortions。 Unexpectedly, small pockets of order persist even above the transit
A bizarre rainforest insect is rewriting what scientists thought they knew about camouflage。 A katydid spotted glowing hot pink in Panama stunned researchers when it slowly transformed into green in just 11 days, perfectly mirroring the life cycle of tropical leaves that emerge pink before maturing。 What once seemed like a rare genetic oddity now a
A major review of 217 trials shows that aerobic exercise is the most effective option for managing knee osteoarthritis。 Activities like walking, cycling, and swimming outperformed other exercise types in reducing pain and improving movement。 While alternatives like strength training and mind-body exercises help, they are best used alongside aerobic
In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the cosmos—they could have helped create dark matter itself。 New research suggests that faint, ancient gravitational waves might have transformed into particles that eventually became the invisible substance shaping galaxies today
A centuries-old vision of a mechanical volcano has finally erupted into reality, as two University of Melbourne engineering students recreated a design first imagined in 1775 by volcanology enthusiast Sir William Hamilton。 Drawing from an 18th-century watercolor and a preserved sketch, they used modern tools like LED lighting and electronic systems
Scientists have created a powerful new way to control quantum systems, achieving the first-ever demonstration of quadsqueezing—an elusive fourth-order quantum effect。 By combining simple forces in a clever way, they made previously hidden quantum behaviors visible and usable, opening new frontiers for quantum technology
Scientists have uncovered the true boundary of the Milky Way’s star-forming region using stellar “age mapping。” They found a telltale U-shaped pattern showing that star formation drops sharply around 35,000–40,000 light-years from the center。 Beyond that, stars are mostly migrants, slowly drifting outward rather than forming in place
A new quantum physics study reveals that simply changing a magnetic field over time can unlock entirely new forms of matter that don’t exist under normal conditions。 By carefully “driving” materials with timed magnetic shifts, researchers created exotic quantum states that could be far more stable and resistant to errors—one of the biggest challeng
Scientists have created tiny “optical tornadoes” — swirling beams of light that twist like miniature whirlwinds — using a surprisingly simple setup based on liquid crystals。 Instead of relying on complex nanotechnology, the team used self-organizing structures called torons to trap and manipulate light, causing it to spiral and rotate in intricate
Coffee doesn’t just energize—it actively reshapes the gut and mind。 Researchers found that both caffeinated and decaf coffee altered gut bacteria in ways linked to better mood and lower stress。 Decaf even improved learning and memory, while caffeine boosted focus and reduced anxiety
