Will Colorado's marmots will be OnlyFans' next big stars? The federal funding crisis has driven UCLA biologist Dan Blumstein's lab to seek new ways to keep the 65-year study running. Long-term studies like this are important to understand how organisms respond to a changing world. 🧪

'We're trying this out of frustration': Marmots star in OnlyFans account as researchers desperately look for ways to raise funds amid US budget cuts

As U.S. federal research budgets continue to be slashed, a team of marmot researchers have turned to unconventional sources of funding.

River riddle solved! The Colorado River disappeared from the geological record for 5 million years. Scientists now know where it went: Into vanished Bidahochi Lake, before eventually spilling over on a course to the Grand Canyon. ucla.in/4dO9niX 🧪

UCLA physicist Eric Hudson's team is working toward a clock based on a nucleus rather than an atom’s electrons, which could keep a steadier rhythm because it would be less sensitive to environmental disturbances such as temperature changes. They've found an answer in Thorium-229. 🧪

Using atomic nuclei could allow scientists to read time more precisely than ever – what this research could mean for future clocks

Atomic clocks undergird modern timekeeping. A nuclear clock could be even more precise.

UCLA researchers have found that rivers in Mars' Jezero Crater delta go back at least 4.2 billion years, suggesting that the window of habitability stretches even further back in time than many scientists had imagined, write Joseph Howlett and @leebillings.bsky.social for @sciam.bsky.social. 🧪

NASA’s Perseverance Mars rover discovers even older lost rivers at Jezero Crater

By plying its ground-penetrating radar in the depths of Mars’s Jezero Crater, this rover has found even older deltas buried beneath those seen on the surface from space

UCLA and UCSD astronomers have detected hydrogen sulfide gas in the atmospheres of four distant gas giants. The sulfur came from evaporated solid matter from the star's disk, proving that they are planets, not brown dwarfs. The method could help identify Earthlike exoplanets. ucla.in/4arfq9A 🔭 🧪

Rarity Public Benefit Corporation is trying to turn a UCLA cure for a rare disease into a medicine. The bottleneck now is not showing that it works, but another key part of the drug approval process — developing the commercial manufacturing. Great story by @carolynyjohnson.bsky.social 🧪

Scientists are inventing treatments for devastating diseases. There’s just one problem.

Gene therapy treatments for rare diseases are being developed, but getting them out of the lab has proved challenging.

UCLA astrophysicist Erik Petigura studied four baby planets in the V1298 Tau system that are becoming super-Earths and sub-Neptunes. Despite being 5 to 10 times Earth’s radius, the planets have masses only 5 to 15 times Earth’s, meaning they are about as dense as Styrofoam. ucla.in/4aPC8Kz 🧪🔭

UCLA-led research has found that by electroplating thorium onto stainless steel, they can excite its nucleus with a laser and measure the electric current it produces. The achievement can be used to miniaturize the nuclear clock. ucla.in/48L8iFL 🧪
