A new study using simulations identified two tipping points for the Greenland Ice Sheet: releasing 1000 gigatons of carbon into the atmosphere will cause the southern portion of the ice sheet to melt; about 2500 gigatons of carbon means permanent loss of nearly the entire ice sheet. Having emitted about 500 gigatons of carbon, we're about halfway to the first tipping point.

The Greenland Ice Sheet covers 1.7 million square kilometers (660,200 square miles) in the Arctic.

Modeling tipping points, which are critical thresholds where a system behavior irreversibly changes, helps researchers find out when that melt might occur.

"For me, mathematics exists in the space between us," Emmy Murphy wrote in accepting the 2020 New Horizons in Mathematics Prize. That space, for her, is a realm of art, perhaps even more than science. And like an artist, she is most fulfilled when exploring the fertile ground where constraint meets creation. The objects she studies are "beautiful to me in the same way that architecture or fashion

A quick, affordable diagnostic test may help curb one of the most prevalent but least discussed sexually transmitted infections, Trichomonas vaginalis . More common than chlamydia or gonorrhea, Trichomonas vaginalis , also known as trich, causes no symptoms in about 70% of those infected. Even when asymptomatic, trich is linked to a host of bad health outcomes, including increased susceptibility

The galaxy JW100 (lower right) features prominently in this image from the NASA/ESA Hubble Space Telescope. The streams of star-forming gas dripping from the disk of the galaxy like streaks of fresh paint are formed by a process called ram pressure stripping. Their resemblance to dangling tentacles led astronomers to refer to JW100 as a "jellyfish" galaxy. JW100 is more than 800 million light-year
