Teens who start using cannabis may experience slower growth in memory, attention, language, and processing speed。 Their abilities often developed normally at first, then began leveling off while nonusers continued improving。 THC appeared to be the most likely driver, especially for worsening memory
Genetic changes may set off a chain reaction that causes the spine’s natural shock absorbers to harden and deteriorate。 Zebrafish with a faulty collagen-related gene developed mineral buildup and spinal fusion similar to human disc disease。 Researchers were able to reduce the damage using an existing osteoporosis drug and by targeting fat metabolis
Beginning around age 50, the brain’s memory center appears to lose many of its longtime immune cells and replace them with more inflammatory ones。 This surprising shift may help explain how normal aging sets the stage for Alzheimer’s disease and dementia
More than 5,000 years after his death, Ötzi the Iceman is still hosting a remarkable mix of ancient and modern microorganisms。 Researchers separated microbes that lived in his body during his lifetime from those that arrived after his death, uncovering traces of his original gut bacteria and cold-loving yeasts that may have survived alongside him i
A ten-month Antarctic experiment found that astronauts may struggle not only with loneliness but also with spending too much time around the same people。 Frequent contact was linked to greater tension and mistrust, while the crew increasingly divided into cultural and language-based groups
A new hollow nanoreactor mimics living cells to make hydrogen peroxide more efficiently using visible light。 Its light-trapping cavity and proton-shuttling shell could open new possibilities for cleaner chemical manufacturing and artificial photosynthesis
Metal-rich asteroids could one day become hardware stores for Mars, supplying the materials needed to build and repair a growing colony。 A new analysis shows that carefully selected asteroids may be reachable with current spacecraft technology。 Some could even provide the ingredients for making rocket fuel in space, dramatically reducing the burden
So i've been working on this project since a few days (or months i should say), it's called wyzer (meaning wiser) it's a statically typed, compiled, resource-oriented programming language with integrated distributed safety via choreographic programming and perceus memory model, The reason why i began this project is out of frustration from Rust, yo
Earth’s molten iron core unexpectedly reversed direction beneath the Pacific, revealing a dramatic change in the hidden engine that creates our planet’s magnetic field。 Satellite data suggest the surge is already weakening, raising the possibility that the deep-Earth upheaval is part of a mysterious natural cycle
