Water-stable catalyst could bring carbon-bond chemistry closer to use in living cells
Olefin metathesis is one of the most important reactions in organic chemistry for forming carbon–carbon bonds—for example, in the production of pharmaceuticals, plastics and complex natural products. However, previous ruthenium catalysts that enable this reaction have faced a maj

Scientists discover first new penguin species in more than 100 years
Genetic evidence has revealed a previously unknown gentoo penguin species on the remote Kerguelen Islands and shown that gentoos actually consist of four distinct species. The discovery also highlights a growing threat, as warming oceans could leave several island populations wit

Plasma treatment helps reveal how molecular coatings dope silicon
Controlling dopant concentration near the silicon surface is increasingly important for ultrashallow junctions and nanoscale devices. Mixed monolayer doping (MMLD) offers a surface-chemistry-based approach in which dopant-containing molecules are mixed with nondopant molecules to

Two-color glowing molecule could make wind tunnel tests more accurate
Most sensors can measure only one thing at a time, like a thermometer for temperature or a pressure gauge for pressure. Measuring two properties accurately from the same surface at the same moment usually means using two separate instruments—adding cost and complexity to the proc
