Dimethyl sulfide, also known as DMS, ... by marine organisms, most notably the microscopic plants known as phytoplankton that live in the nutrient-rich upper layer of the ocean.

Scientists have announced the detection of dimethyl sulfide—a chemical that, on Earth, is only produced by living organisms—in the atmosphere of an exoplanet called K2-18b.; This is the second ...

In this case, scholars at the University of Cambridge inferred K2-18b's atmosphere contains dimethyl sulfide, which on Earth, is only produced by living organisms, primarily marine algae and microbes.

If dimethyl sulfide and dimethyl disulfide are in K2-18b's atmosphere, and if they're from biological activity, "it would represent a groundbreaking moment in the search for extraterrestrial life ...

The team’s work repeats the 2023 detection and adds further credence to the possibility of life on the relatively nearby exoplanet—assuming the findings are sound and that dimethyl sulfide is ...

Both dimethyl sulfide and dimethyl disulfide, which are part of the same chemical group, have overlapping characteristics, which is why the results can’t definitively differentiate between the ...

A chemical called dimethyl sulfide popped up in an analysis of exoplanet K2-18b’s atmosphere. On Earth, it’s only made by living organisms.

Astronomers using the James Webb Space Telescope confirmed that the planet K2-18b has traces of dimethyl sulfide, a potential biosignature of marine microorganisms.

Dimethyl sulfide is cool—and a potential biosignature—but scientists are urging caution before we declare a plankton party some 120 light-years away.

On Earth, these are only produced by life, particularly by marine microbes. Madhusudhan, despite his enthusiasm, ... The team announced this possible detection of dimethyl sulfide in 2023, ...

Dimethyl sulfide is the largest natural source of atmospheric sulfur on Earth, which means that it gets into the atmosphere and cycles around. But it starts its journey in the ocean.

Both dimethyl sulfide and dimethyl disulfide, which are part of the same chemical group, have overlapping characteristics, which is why the results can’t definitively differentiate between the ...
