As newborn neurons make their way through the developing brain, they must squeeze through incredibly tight spaces to reach their final destinations。 Researchers discovered that this physical journey routinely causes some of the most severe forms of DNA damage—double-strand breaks—yet the young brain has evolved an impressive ability to repair the d
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
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
Astronomers may be closing in on a long-standing cosmic mystery: why some of the universe’s biggest galaxies seem to have far fewer stars than expected。 Using NASA- and JAXA-supported XRISM observations of a galaxy called NGC 4151, researchers found strong evidence that supermassive black holes can unleash powerful winds that blow away the raw mate
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
Coherence Neuro has started testing a brain-computer interface that could one day use electrical stimulation to prevent tumors from growing
Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species。 Even more surprising, some show little sign of physical decline as they age。 Their unusual pollen-feeding lifestyle may play a role, but the research suggests deeper evolutionary changes are also helpin
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
As tech giants rush to build infrastructure, some residents who live near data centers say a constant low-frequency vibration is ruining their health and homes
Scientists have proposed a new method for finding tightly bound supermassive black hole pairs by searching for stars that flash repeatedly as their light is magnified by the black holes’ gravity。 The timing and brightness of these bursts could provide a unique fingerprint of black holes slowly spiraling toward a future collision
A surprising new study suggests the earliest primates didn't originate in tropical forests but in cold, dry parts of North America。 Some may have even survived seasonal Arctic conditions by slowing their metabolism or hibernating。 Researchers found that dramatic climate shifts, rather than warmth, played a major role in driving primate evolution an
A new SETI study suggests we may be overlooking alien signals not because they aren't there, but because their own stars are scrambling them before they escape into space。 Turbulent plasma and powerful stellar storms can spread an ultra-narrow radio transmission across a wider range of frequencies, making it much harder for traditional searches to
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
The mysterious Amaterasu particle may not be a proton at all。 New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better able to retain their energy while traveling through space。 This idea could help explain how these rare particles reach Earth and provide new clues about
One of the most celebrated claims about Yellowstone’s wolves is facing a major challenge。 Scientists say the study behind the famous trophic cascade story relied on flawed methods that overstated the ecological impact of wolf recovery。 Their reanalysis found no evidence for a dramatic, park-wide surge in willow growth
Himalayan villages are creating artificial glaciers to guarantee water for their crops in the spring
