A study by an international team of researchers, including from the University of Washington, determines that carved stone tools, also known as Levallois cores, were used in Asia 80,000 to 170,000 years ago.

Researchers at the University of Minnesota and the Somali, Latino, and Hmong Partnership for Health and Wellness have new evidence that the gut microbiota of immigrants and refugees rapidly Westernize after a person's arrival in the United States. The study of communities migrating from Southeast Asia to the US, published Nov. 1 in the journal Cell, could provide insight into some of the metabolic health issues, including obesity and diabetes, affecting immigrants to the country.
A joint study by the BBC, UCL and the University of Barcelona shows that in virtual reality news experiences, basic interactivity can increase buy-in without compromising faithful reporting.
