Researchers at UC San Diego have demonstrated that a key cellular enzyme can accurately read an eight-letter genetic alphabet, doubling the four letters used by all known life on Earth. Detailed imaging revealed that RNA polymerase handles synthetic DNA letters in surprisingly similar ways to…
A giant iceberg measuring more than 76 square kilometers broke from Greenland’s Petermann Glacier in August 2026, marking the Arctic’s largest glacier calving event since 2020. The berg later slammed into Joe Island but survived without breaking apart, and satellites are now tracking it as…
Scientists used Earth’s magnetic field and atmosphere as a planet-sized detector to search for some of the lightest proposed forms of dark matter. The approach dramatically improved limits on ultralight axions and uncovered several intriguing dark photon signals that still need to be explained.
Slow breathing with a prolonged exhale made people more willing to take risks by changing heart activity and increasing the brain’s sensitivity to rewards. The findings suggest that something as simple as controlling your breath can directly influence how you evaluate choices.
A huge 10-sided atmospheric pattern has appeared around Saturn’s south pole, giving the planet a surprising counterpart to its famous northern hexagon. Hubble data suggest the strange decagon only began emerging in the past few years and is still growing stronger. Researchers hope continued observations…
Following nearly 10,000 older women for 10 years, researchers found that tea drinking was associated with slightly higher hip bone density. Moderate coffee consumption did not appear harmful, but drinking more than five cups a day was linked to lower bone density. The findings suggest…
Snake embryos begin life curled into a distinctive right-handed spiral, and scientists may finally know why. Their bodies grow faster than their guts, creating a tether that forces the lengthening embryo to buckle and twist inside the egg. Researchers reached the conclusion after studying more…
A long-standing picture of brain evolution as newer, rational layers stacked on top of an ancient “lizard brain” may be deeply misleading. Researchers found that evolution instead appears to balance two competing styles of brain wiring, expanding one while shrinking the other depending on what…
Ancient footprints in Kenya reveal that eight Paranthropus boisei may have traveled together 1.4 million years ago, with some individuals reaching surprisingly large, human-like body sizes. The tracks offer a rare glimpse of their social behavior and suggest these extinct human relatives may have lived…
Physicists have mathematically captured a bizarre “spacetime crystal” that can either dissolve or collapse into a microscopic black hole after only a tiny change in energy. Their breakthrough came from an unusual trick involving infinitely many dimensions, potentially giving researchers a new tool for studying…
