Imitation, the old saying goes, is the sincerest form of flattery. It also appears to be an ancient interpersonal mechanism that promotes social bonding and, presumably, sets the stage for relative strangers to coalesce into groups of friends, according to a new study.

A new review says using magnetic resonance imaging (MRI) before surgery to assess the extent of early breast cancer has not been shown to improve surgical planning, reduce follow-up surgery, or reduce the risk of local recurrences.

Arizona researchers compared the survival rates in out-of-hospital cardiac arrest patients treated with positive-pressure ventilation (bag-valve mask) vs. passive oxygen flow. Survival was higher (38.2 percent) with passive oxygen flow than with assisted ventilation (25.8 percent). This study reinforces the notion that survival of out-of-hospital cardiac arrest might have more to do with circulating the [...]
Recent research into the properties of graphene nanoribbons provides two new reasons for using the material as interconnects in future computer chips. In widths as narrow as 16 nanometers, graphene has a current carrying capacity approximately a thousand times greater than copper — while providing improved thermal conductivity.

Louis Armstrong sang, “When you’re smilin’, the whole world smiles with you.” Romantics everywhere may be surprised to learn that psychological research has proven this sentiment to be true — merely seeing a smile (or a frown, for that matter) will activate the muscles in our face that make that expression, even if we are [...]
The thinning of a gigantic glacier in Antarctica is accelerating, scientists report. The Pine Island Glacier in West Antarctica, which is around twice the size of Scotland, is losing ice four times as fast as it was a decade years ago. The research also reveals that ice thinning is now occurring much further inland.

Although open-heart surgery is a frequent treatment for heart disease, it remains extremely dangerous. Now groundbreaking research has shown the potential for an injected protein to regrow blood vessels in the human heart — eliminating the need for risky surgery altogether.

Chemists have discovered how to make molecules with a twist — the molecules fold in to twisted helical shapes that can accelerate selected chemical reactions. The research could yield valuable methods for making pharmaceuticals and other chemicals that require precise assembly of complex structures.
