Scientists have created record-breaking X-ray flashes lasting just 300 attoseconds, concentrating enormous power into an incredibly tiny spot. The breakthrough could unlock a new way to observe electrons in action and potentially control the ...

A surprising new study suggests that a stronger flu shot could offer older adults significantly greater protection against Alzheimer's disease. Researchers at UTHealth Houston analyzed nearly 200,000 adults ages 65 and older and found that those who ...

A study of more than 17,700 US adults found that people who use cannabis in multiple forms have dramatically higher rates of daily consumption and addiction symptoms than those who stick primarily to one method. Nearly 67% of those who used almost .. ...

Mysterious gas emissions and fresh volcanic fissures suggest that Mars may not be geologically dead after all, with hot magma potentially still active deep underground. The discovery could point to hidden pockets of warmth and chemical energy capable ...

Scientists have discovered a surprising quantum limit that prevents electrons from being tracked with unlimited precision in both space and time. The breakthrough could pave the way for manipulating chemical reactions and developing electronics ...

Drinking two to three cups of caffeinated coffee daily was linked to a dramatically lower risk of dementia and better cognitive functioning in a study spanning up to 43 years. The benefits appeared regardless of genetic risk, but decaffeinated coffee ...

Humans collectively produce more than 2 billion tonnes of carbon dioxide annually just by turning food into energy, a 74% increase over three decades largely driven by population growth. Unlike fossil fuel emissions, however, the CO2 we exhale is ...

Scientists have uncovered evidence that Europe was dominated for more than 20 million years by open woodlands, colorful meadows, and large grazing animals, not the dense forests long considered its natural state. The surprising discovery challenges . ...

The Vera C. Rubin Observatory has already uncovered two previously unknown companions of the Milky Way using preliminary observations covering just 7% of the night sky. The discoveries include an extremely faint galaxy 355,000 light-years away and a ...
