A new study co-led by Indiana University that tracked the eye movement of twins finds that genetics plays a strong role in how people attend to their environment. Conducted in collaboration with researchers from the Karolinska Institute in Sweden, the study offers a new angle on the emergence of differences between individuals and the integration of genetic and environmental factors in social,…
Researchers in the University of Wisconsin–Madison Department of Biochemistry have discovered that a cellular pump known to move drugs like antibiotics out of E. coli bacteria has the potential to bring them in as well, opening new lines of research into combating the bacteria. The discovery could rewrite almost 50 years of thinking about how these types of transporters function in the…
When the ancestors of modern humans migrated out of Africa, they passed through the Middle East and Turkey before heading deeper into Asia and Europe. Here, at this important crossroads, it’s thought that they encountered and had sexual rendezvous with a different hominid species: the Neanderthals. Genomic evidence shows that this ancient interbreeding occurred, and Western Asia is the most likely…
In 2013, an influenza virus that had never before been detected began circulating among poultry in China. It caused several waves of human infection and in late 2016, the number of people to become sick from the H7N9 virus suddenly started to rise. As of late July 2017, nearly 1,600 people had tested positive for avian H7N9. Nearly 40 percent…
Scientists attending a recent meeting of the American Society for Microbiology reported they had uncovered a highly disturbing trend. They revealed that bacteria containing a gene known as mcr-1 – which confers resistance to the antibiotic colistin – had spread round the world at an alarming rate since its original discovery 18 months earlier. In one area of China, it…
Sixty years ago, a team of scientists went looking for yellow fever in the jungles that line the northwestern edge of Lake Victoria. What they found instead, in the blood of a rhesus monkey, was a new virus, one they named for the area’s dense vegetation: Uganda’s Zika Forest. Within a few years, Zika virus was showing up in humans, causing a pink…
