New method uses light to enable the generation of non-canonical amino acids
UC Santa Barbara researchers are building out the repertoire of chemical reactions, using light. In a paper published in the journal Nature, chemistry professor Yang Yang and collaborators at the University of Pittsburgh report a method using photobi.....»»
Historic iceberg surges offer insights on modern climate change
A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs, and the havoc it wrought was on the ocean current itself......»»
Microscopic defects in ice influence how massive glaciers flow, study shows
As they seep and calve into the sea, melting glaciers and ice sheets are raising global water levels at unprecedented rates. To predict and prepare for future sea-level rise, scientists need a better understanding of how fast glaciers melt and what i.....»»
New sulfur-free catalyst enables efficient green diesel production
Green diesel, a blend of diesel-grade hydrocarbons derived from renewable oils such as vegetable oils and animal fats, offers a promising alternative to traditional petroleum diesel. With a chemical composition similar to petroleum diesel, it integra.....»»
