Grist reports that penguin guano in Antarctica may help cool the region by forming clouds through ammonia release, but ...

Scientists may have just found alien life—on a distant ocean world 124 light-years away. Dimethyl sulfide, a known ...

I learned that potential signs of life were discovered on an exoplanet called K2-18b, which is 120 light-years away from Earth.

While the molecules identified on K2-18b by the April study — dimethyl sulfide, or DMS, and dimethyl disulfide, or DMDS — are associated largely with microbial organisms on our planet, scientists ...

Dimethyl sulfide, also known as DMS, sounds like it could be a chemical compound you'd try to avoid on an ingredient label, or the poisonous ingredient in a murder mystery. But some scientists ...

Last month, astronomers using the James Webb Space Telescope made headlines by announcing they had detected hints of the chemicals dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) on the planet.

First discovered in 2015 by the Kepler Space Telescope, K2-18b quickly drew attention. It is roughly 2.6 times Earth’s diameter, making it unlike anything in our solar system—a so-called “hycean” ...

This April, news reports linked the stinky gas dimethyl sulfide (DMS) in the atmosphere of a distant exoplanet called K2-18b to possible life on it. The reports, prompted by work led by astronomer ...

But an abiotic source of DMS has been reported from photochemical reactions involving hydrogen sulfide and methane. 5 Some planetary scientists argue that it seems unlikely any putative biosignature ...
