Analyzing data gathered by the James Webb Space Telescope, scientists discovered that an exoplanet named HD 189733 b, ...

Hydrogen sulfide SMAC values will define safe limits for spaceflight crews on future missions and could drive new requirements for monitoring and mitigation of this chemical during spaceflight.

Mark Roth's pioneering work on hydrogen sulfide has spawned Ikaria, a company exploring the molecule's potential to modulate the body's metabolism and perhaps one day turn hibernation into ...

One of the most foul-smelling substances is hydrogen sulfide (H 2 S), which has a characteristic rotten-egg odor. This gas is produced by the anaerobic (oxygen-free) breakdown of organic matter by ...

Since the end of November, the San Diego Air Pollution Control District has measured hydrogen sulfide levels above the California safety threshold in the Nestor area more than 15 times.

Since they came online, the air monitors have repeatedly detected levels of hydrogen sulfide – one of the main chemical components of sewer gas – above the state threshold of 30 parts per ...

Hydrogen sulfide, a toxic gas that smells like rotten ... ocean-covered exoplanet K2-18 b by detecting dimethyl sulfide, a molecule previously only known to be created by living organisms on ...
