In Amazon Wars, Bands of Brothers-in-law
SALT LAKE CITY, Oct. 27, 2014 – When Yanomamö men in the Amazon raided villages and killed decades ago, they formed alliances with men in other villages rather than just with close kin like chimpanzees do. And the spoils of war came from marrying their allies' sisters and daughters, rather than taking their victims' land and women.
Teens Still Sending Naked Selfies
A new study from the University of Utah confirms that substantial numbers of teens are sexting – sending and receiving explicit sexual images via cellphone. Though the behavior is widely studied, the potentially serious consequences of the practice led the researchers to more accurately measure how frequently teens are choosing to put themselves at risk in this fashion.
Asteroid Named for University of Utah Makes Public Debut
SALT LAKE CITY, Sept. 23, 2014 – What's rocky, about a mile wide, orbits between Mars and Jupiter and poses no threat to Earth? An asteroid named "Univofutah" after the University of Utah. Discovered on Sept. 8, 2008, by longtime Utah astronomy educator Patrick Wiggins, the asteroid also known as 391795 (2008 RV77) this month was renamed Univofutah by the International Astronomical Union's Minor Planet Center in Cambridge, Massachusetts.
University of Utah Engineers Unlock Potential for Faster Computing
SALT LAKE CITY, Sept. 22, 2014 – University of Utah engineers discovered a way to create a special material – a metal layer on top of a silicon semiconductor – that could lead to cost-effective, superfast computers that perform lightning-fast calculations but don't overheat. This new "topological insulator" behaves like an insulator on the inside but conducts electricity on the outside and may pave the way for quantum computers and fast spintronic devices.
Firelight Talk of the Kalahari Bushmen
SALT LAKE CITY, Sept. 22, 2014 – After human ancestors controlled fire 400,000 to 1 million years ago, flames not only let them cook food and fend off predators, but also extended their day.
