Emerging research suggests that the gas hydrogen sulfide, produced in the gut and released during flatulence, may help lower blood pressure by causing blood vessels to dilate, highlighting a potential link between gut health and cardiovascular health. However, further studies are needed, and the research does not recommend unregulated flatulence or drastic dietary changes.

Scientists using the James Webb Space Telescope have detected hydrogen sulfide, a molecule that smells like rotten eggs, in the atmosphere of the exoplanet HD 189733b. This discovery marks the first time hydrogen sulfide has been found outside our solar system and provides new insights into the atmospheric composition of exoplanets. HD 189733b, a "hot Jupiter" known for its extreme weather, including glass rain and high temperatures, also contains water, carbon dioxide, and carbon monoxide. The findings, published in Nature, enhance our understanding of exoplanet formation and atmospheric chemistry.

Astronomers have determined that Uranus likely smells like farts and rotting eggs due to the presence of hydrogen sulfide gas in its cloud cover, as detected by the Near-Infrared Integral Field Spectrometer. This gas gives off the distinctive smell of rotting eggs, and if humans were to descend into Uranus' atmosphere, they would likely find the smell nauseating. Additionally, researchers believe that Uranus and Neptune may also have ammonia ice in their clouds, contributing to the planet's unique and unpleasant aroma.

A new study suggests that a surge of hydrogen sulfide gas may have played a significant role in the mass extinction event that occurred around 530 million years ago, wiping out 45% of all ocean animals. Previously, it was believed that low-oxygen conditions were the primary cause of the die-off. The researchers found high levels of molybdenum in sediment samples from the extinction period, indicating the presence of hydrogen sulfide in the water. The surge of this toxic gas may have been triggered by an explosion of organic matter, which led to the depletion of oxygen and the subsequent release of hydrogen sulfide. Further research is needed to determine the exact cause of the anoxic conditions and the sulfidic wave that followed.

Scientists have discovered a new gut bacterium, Taurinivorans muris, that feeds on taurine and produces hydrogen sulfide. While hydrogen sulfide has protective properties against certain pathogens, excessive amounts can harm gut health. This finding provides insights into the roles of taurine and hydrogen sulfide in the gut and their broader health implications, contributing to the development of future microbiome-based therapies.

Researchers from the University of Exeter have discovered that targeting tiny amounts of hydrogen sulfide (H2S) to specific areas of cells using a H2S-releasing molecule called AP39 can greatly improve health and activity as organisms age. By specifically targeting H2S to the mitochondria, the energy-generating machinery of cells, this approach could potentially be used as a therapeutic for healthy aging. The study, conducted on worms, found that administering AP39 improved mitochondrial integrity, kept muscles active, and extended healthspan. The research also identified a group of proteins that regulate gene expression in aging, potentially opening up new targets for therapy in age-related conditions. The underlying technology has been assigned to the spin-out company MitoRx Therapeutics, which aims to develop next-generation compounds for combating diseases of aging.

Scientists at Texas A&M University Health Science Center have discovered that a nano-sized carbon material derived from the oxidation of carbon-rich sources could potentially be used to treat Down syndrome and other disorders associated with high levels of hydrogen sulfide. The carbon nanomaterial acts as a mediator of therapeutic reactions and has shown the ability to improve function and survival in Down syndrome-derived cells. Rather than blocking the production of hydrogen sulfide, the material converts it into beneficial metabolites, offering potential therapeutic implications. Further research is needed to explore the full range of applications for these carbon-based materials.
