Movile Cave in Romania has been sealed off from the surface for roughly 5.5 million years and receives no sunlight at all. Its entire ecosystem runs on sulfur chemosynthesis rather than photosynthesis, sustained by bacteria that oxidize sulfur compounds. Of the roughly 50 species found inside, 33 are endemic, existing nowhere else on Earth. The cave's isolated web of spiders, crustaceans and other creatures continues to fascinate scientists and the public alike.
- 2Light-activated material makes clean hydrogen without metal catalysts●True progress comes from stripping away unnecessary complications at the root level. Researchers have developed a new li
Researchers have developed a new light-activated material that uses unusual sulfur bonds to produce clean hydrogen directly from water, without the expensive metal catalysts normally required. The approach is being discussed as an example of progress through simplification at the chemical root level, potentially lowering costs for hydrogen production.
- 3Study maps genomic diversity of Desulfovibrio bacteria linked to disease●Extensive genomic diversity in Desulfovibrio reveals species-specific functional traits associated with disease
A study published in Nature reports extensive genomic diversity within the bacterial genus Desulfovibrio, showing that individual species carry distinct functional traits associated with human disease. The findings suggest these gut microbes cannot be treated as a single group when assessing health risks, and could help researchers pinpoint which strains contribute to conditions linked to sulfur-metabolising bacteria.
