WSU geneticist helps solve mystery of Arctic peoples

With help from a Washington State University population geneticist, Danish researchers have concluded that North America and the Arctic were settled in at least three pulses of migration from Siberia. First came the ancestors of today’s Native Americans, then Paleo-Eskimos – the first to settle in the Arctic – followed by the ancestors of today’s Inuit.

The research, published in the journal Science, settles nearly a century of debate over Arctic settlement and whether today’s Inuit are related to Paleo-Eskimos, who disappeared 700 years ago. That’s about the time the technologically superior Inuit reached Greenland, but the researchers could not tie the disappearance of the Paleo-Eskimos to the Inuit’s arrival.

Alien life could thrive on ‘supercritical’ C02 instead of water

Alien life might flourish on an exotic kind of carbon dioxide, according to a new study co-authored by Dirk Schulze-Makuch, professor at Washington State University’s School of the Environment. This “supercritical” carbon dioxide, which has features of both liquids and gases, could be key to extraterrestrial organisms much as water is to biology on Earth. » More …

Growth mindset study seeks to expand to area high schools

Believing in your ability to learn can make you smarter. This is the idea Joyce Ehrlinger, assistant professor of psychology at Washington State University, is bringing to high school classrooms in the Inland Northwest.

For the last year, Ehrlinger and a team of researchers have worked with math students at Pullman and Moscow high schools to develop a growth mindset, the belief that the ability to learn is not fixed by your IQ but can be developed through dedication and hard work. She is currently looking to expand the study to high schools in Spokane, the Tri-Cities and elsewhere in the region.

“Say you fail a math test. For someone who thinks math is an ability you either have or don’t have, this negative feedback makes them pull away from math completely,” Ehrlinger said. “For someone with a growth mindset, failing a test is not a complete overarching statement about them as a person and their abilities; rather, it gives them specific information about where they can improve.”

Ehrlinger’s post-doctoral work with Stanford psychologist Carol Dweck provided conclusive evidence a growth mindset ultimately leads to higher grades, higher SAT scores and greater confidence to tackle difficult subjects. However, psychologists do not have a strong understanding of why or how the growth mindset helps overall performance.

Ehrlinger’s hope is to fix this with her current study.

“Where does that bottle, leftover food or old laptop go when you dispose of it?” Kabasenche asks. “Our trash is out of sight but should it be out of mind? What are the ethical issues we should think about in disposing of our waste?”
