A new study published in the journal npj Climate and Atmospheric Science, shows that electronically tagged sharks can serve as mobile sensors, collecting ocean climate data in regions that are difficult to observe using conventional methods.

Manganese dioxide can convert amino acids into hydrogen cyanide (HCN) without requiring methane, solving a long-standing puzzle about the origin of this key prebiotic molecule on early Earth, as reported by researchers from Science Tokyo. Although HCN is central to origin-of-life theories, recent evidence suggests early Earth's atmosphere didn’t contain sufficient methane needed for classic HCN-producing reactions. The newly found chemical pathway shows that HCN could instead have been continuously supplied from abundant amino acids.

Dan M. Frangopol, the inaugural Fazlur R. Khan Endowed Chair of Structural Engineering and Architecture Emeritus and professor emeritus of civil and environmental engineering at Lehigh University, has been selected to receive the 2026 Arthur M. Wellington Prize from the American Society of Civil Engineers (ASCE).

Tiny plankton shells used to reconstruct past polar ocean temperatures may contain two different chemical stories, a new study by iC3 researchers has found. 

The work shows that Neogloboquadrina pachyderma, a key species in polar climate archives, can grow an outer shell crust with a different chemical make-up from the shell beneath it, even when both are grown in the same conditions.

This discovery could help scientists produce more accurate records of past ocean change.
