Laughing gas and the mystery of Carl Sagan's Faint Young Sun Paradox: When the sun shone dimmer an eon ago, Earth remained warm in spite of it likely thanks to a mix of greenhouse gases. Biogeochemists have now shown how N20, known today for its use as a dental anesthetic, may have made it into the mix.
For ants and robots operating in confined spaces like tunnels, having more workers does not necessarily mean getting more work done. Just as too many cooks in a kitchen get in each other’s way, having too many robots in tunnels creates clogs that can bring the work to a grinding halt.

What does flying in a commercial airliner have in common with working at the office or relaxing at home? According to a new study, the answer is the microbiome – the community of bacteria found in homes, offices and aircraft cabins.
By instructing key immune system cells to accept transplanted insulin-producing islets, researchers have opened a potentially new pathway for treating type 1 diabetes. If the approach is ultimately successful in humans, it could allow type 1 diabetes to be treated without the long-term complications of immune system suppression.
