@sciencex.bsky.socialZinc-air batteries completed up to 500 charge–discharge cycles in experiments with a long-lasting catalyst. Reliable operation hinges on a stable contact area inside the cell. doi.org/hcm566
@sciencex.bsky.socialSuckling anatomy appears to have begun evolving nearly 165 million years ago, before modern mammals arose. A Jurassic fossil preserves tiny bony hooks resembling those in living mammals. doi.org/rr85
@sciencex.bsky.socialWord meanings appear to be represented across groups of hippocampal neurons, with activity during spoken stories reflecting relationships between meanings and their context. doi.org/hcm55d
@sciencex.bsky.socialArctic sea ice extent could be forecast up to nine months ahead with a simple algorithm. Its September forecast error was comparable to that of 34 seasonal models. doi.org/hcm548
@sciencex.bsky.socialSpinach nanoparticles activated by red light improved pumping in rats with induced heart failure. Whether enough light could reach a human heart remains unresolved. doi.org/hcm542
@sciencex.bsky.socialJonathan, a 194-year-old tortoise, retains youthful order in genetic switches linked to mitochondrial energy production. The longevity signal still needs validation. doi.org/hcms6z
@sciencex.bsky.socialZimbabwe’s newly named, 4.5-meter Musango adds to a dinosaur fauna distinct from South Africa’s, despite similar rock ages and geographic proximity.
@sciencex.bsky.socialIntensive breathwork reduced brain blood flow by around 45%, but brain-network changes appear key to the altered states reported by 30 experienced practitioners. The findings are preliminary.
@sciencex.bsky.socialAbout two daily servings of unsalted, skin-roasted peanuts improved insulin responsiveness in memory-related brain regions after 16 weeks in healthy older adults. doi.org/hcm53t
@sciencex.bsky.socialUltraviolet laser pulses changed diamond defects while existing nitrogen-vacancy centers’ optical signals stayed largely unchanged. The new defects’ precise structures remain unresolved. doi.org/hcm53h
@sciencex.bsky.socialBrief safety reminders cut potentially harmful AI choices from 16.6% to 10.1% in clinical tests. Unsafe choices persisted despite improvements in 19 of 20 models. doi.org/hcm53b
@sciencex.bsky.socialNew stability rules separate quantum phases an older method wrongly labels as identical, including a generic product state and a maximally dephased toric code. The framework is not yet universal. doi.org/hcm52p
@sciencex.bsky.socialA magnitude 7.7 earthquake in Panama triggered tsunami warnings. Waves up to 3 meters high could hit the coastline in the coming hours.
@sciencex.bsky.socialAdults whose fathers held the least advantaged jobs had death rates around 26% higher than those whose fathers held the most advantaged jobs. The association does not prove causation. doi.org/hcm5v8
@sciencex.bsky.socialAn EU offshore wind focus could mean 22% less wind and solar capacity by 2050, yet retain 93% of the rare earth requirement for added equipment compared with full expansion. doi.org/hcm5tc
@sciencex.bsky.socialAbout 65% of preschool boys in Norway chose a character from the larger cartoon group. Girls showed no clear preference, and the cues influencing children's choices remain unclear. doi.org/hcm5tb
@sciencex.bsky.socialA healthy Nordic diet may lower 24-year death risk, modeling suggests. The estimated reduction was 2.67 percentage points versus usual eating habits; severe liver protection remains unclear. doi.org/hcks8v
@sciencex.bsky.socialCoral reefs and chimpanzee populations can thrive despite environmental pressures. Conservation bright spots often share strong community involvement and respect for local knowledge.
@sciencex.bsky.socialMECP2 regulatory variants may help explain autism’s fourfold diagnosis gap between boys and girls. One variant lowered gene expression by about 30% in human neurons. doi.org/hcm43d
@sciencex.bsky.socialStigmatomma pallipes brains appear to reach maximum size before adulthood. This Dracula ant species starts hunting immediately, without an age-based transition from nursing to foraging. doi.org/chk66j
