AI just created a virus not found in nature and scientists are worried
The technique could lead to new treatments for antibiotic-resistant bugs, but some scientists say the technology could be misused
Lactobacillus metabolite boosts fertility in older mice
A metabolite from *Lactobacillus crispatus* improved pregnancy outcomes in older mice by 30% and may help preserve fertility in aging uteruses. Human trials are needed to confirm if this postbiotic effect translates to …
Bacteria and archaea evolved independently from LUCA
Life on Earth may have started twice, as bacteria and archaea likely evolved independently from LUCA, a primitive ancestor dependent on hydrothermal vent metals. This suggests life could arise more easily elsewhere in t…
Scientists have demonstrated that heat can move through a crystal in focused, wave-like rays at room temperature instead of spreading randomly. The breakthroug…
Astronomers have found evidence that one of the most massive white dwarfs known has an oxygen-neon core instead of the more common carbon-oxygen core. The find…
Uberaba Geopark in Brazil, a 3,900 sq km site with 90-million-year-old fossils, was designated a Global Geopark to protect its Late Cretaceous-era dinosaur rem…
NASA’s Voyager 2 survives daring ‘big bang’ maneuver After 49 years in space, NASA’s Voyagers are running low on power—but an audacious move should extend the…
Short, frequent breaks—especially with physical activity—boost energy and motivation more than long, uninterrupted work sessions, improving performance and red…
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. Frequ…
A new yarn combines the stretch of spandex with the recyclability of a single plastic, offering a potential path toward more sustainable clothing.
Folding a standard sheet of paper 42 times makes it thick enough to reach the moon because each fold doubles the thickness exponentially. This demonstrates how…
Smoking in movies and TV is up, and “cigfluencers” have become a thing, but lags in data make it unclear if the vibe shift has any reality to it
Earth’s molten iron core unexpectedly reversed direction beneath the Pacific, revealing a dramatic change in the hidden engine that creates our planet’s magnet…
Voyager 1 is running low on power for science, but a successful energy-saving maneuver on Voyager 2 raises hope that the 50-year-old spacecraft can keep going.
