Space-based and ground observations reveal L 98-59 d as a 1.6× Earth's size exoplanet with a global magma ocean and a sulfur-rich atmosphere likely dominated by hydrogen sulfide and sulfur dioxide, suggesting it formed from a larger sub-Neptune and cooled over billions of years. This lava-world represents a new class of planets and highlights the surprising diversity of worlds beyond our solar system.
A new study reveals that oceans may cool the Earth more than previously thought, due to sulfur gases like methanethiol emitted by marine life, which create aerosols that reflect solar radiation. This discovery suggests that climate models have overestimated solar radiation reaching the Southern Ocean, highlighting the need for more accurate models. The research emphasizes the role of oceanic sulfur compounds in climate regulation, potentially impacting climate change policies.
Researchers at Flinders University’s Australian Wine Research Institute have found that adding gold nanoparticles to wine can improve its aroma by trapping sulfur compounds. The particles can be removed and reused, making the process cost-effective. The nanosurfaces can also be added to packaging materials and filtration devices. The study found that the gold nanoparticles consistently removed the same or more hydrogen sulfide from both white and red wines than copper fining, without affecting desirable sulfur compounds.
