    Blowing in the (Stellar) Wind

    It is theorized that massive stars have lighter elements on the outside, heavier ones at the core, and that there must be a layer where these meet – and where, possibly, nitrogen is formed. Taking measurements just 15 hours after a star exploded in a supernova, astrophysicists found nitrogen – and shed new light on the origins of the universe.

    Super-Slick Material Makes Steel Better, Stronger, Cleaner

    Harvard reports the creation of the ""most durable anti-fouling material to date,"" which protects and improves steel. Dr. Alexander Tesler, a former postdoc at Harvard and now a research fellow in the Weizmann Institute's Department of Materials and Interfaces, led the research into a way to make steel safer and less susceptible to corrosion.

    Rita J. King, Co-Director of Science House and Weizmann Advocate for Curiosity, writes about ""the incredible"" Prof. Noam Sobel's findings that people tend to sniff their hands – subconsciously, of course – after shaking someone else's hand. Perhaps counterintuitively, we actually sniff longer after shaking the hand of someone of the same gender.
