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
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
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
Scientists at the University of Hong Kong have created a remarkable new type of brain-inspired chip that can function just above absolute zero, one of the coldest environments imaginable。 By using a standard silicon carbide transistor in a completely new way, the team made a single device behave like an energy-efficient neuron, firing electrical “s
JWST has revealed dramatic differences between the dawn and dusk regions of the scorching exoplanet WASP-121 b。 Fierce winds appear to carry heat from the planet’s permanent dayside, making the evening side hotter and more expanded。 Scientists also found signs that water is being broken apart by extreme temperatures and that mysterious mineral clou
NASA says a long-running air leak aboard the ISS recently worsened, leading engineers to investigate new suspected crack locations and consider a riskier repair strategy。 Astronauts were temporarily moved into a safe haven as a precaution before the repair was postponed for further analysis
Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world。 Researchers say the answer isn’t to stop following current events—it’s to build healthier habits around how, when, and where we get our news
A clever nanoscale redesign may have solved one of superconductivity’s biggest problems。 Researchers in Sweden discovered that by subtly sculpting the surface beneath an ultrathin superconducting material, they could make it stay superconducting at higher temperatures and under much stronger magnetic fields
A new technique could solve one of the biggest challenges in making future computer chips from ultrathin materials。 Researchers found that coating molybdenum disulfide with oxygen or fluorine lets manufacturers remove just the top layer of atoms much more safely during plasma processing。 The result is a cleaner, more controlled path toward smaller
Scientists found that transfer learning can make the search for new physics in the universe much faster, slashing the need for expensive simulations。 Yet the approach can backfire when AI relies too heavily on familiar patterns, potentially missing evidence of something truly new
Researchers found that a Chinese sodium-ion battery performs far better than expected, with production quality and design features comparable to Tesla’s batteries。 If engineers can improve cold-weather charging and energy density, sodium could become a cheaper and more abundant alternative to lithium for EVs and large-scale energy storage
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
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
In February, a Trump official refused to review the vaccine
Using the Keck Observatory, astronomers measured the spins of dozens of giant planets and brown dwarfs orbiting distant stars。 They found that giant planets can spin faster than much more massive brown dwarfs, challenging simple assumptions about mass and rotation。 The results suggest that magnetic fields and formation processes play a major role i
Astronomers have spent years searching for a possible hidden giant planet far beyond Neptune。 Unusual orbits among distant Kuiper Belt objects have fueled the Planet Nine theory, but recent discoveries are challenging the idea by showing more stable motion than expected。 If Planet Nine exists, it may be much farther away than originally thought
