Mystery solved about the machines that move your genes

Fleets of microscopic machines toil away in your cells, carrying out critical biological tasks and keeping you alive. By combining theory and experiment, researchers have discovered the surprising way one of these machines, called the spindle, avoids slowdowns: congestion. The spindle divides chromosomes in half during cell division, ensuring that both offspring cells contain a full set of genetic material. […]

Smaller class size means more success for women in STEM

A new study demonstrates that increasing class size has the largest negative impact on female participation in science, technology, engineering and mathematics (STEM) classrooms, and offers insights on ways to change the trend. Using data obtained from 44 science courses across multiple institutions — including Cornell, the University of Minnesota, Bethel University and American University in Cairo — a team […]

How humans reduce uncertainty in social situations: Scientists propose a psychological model of three interrelated ways people reduce uncertainty in social situations

Do my friends find me funny? Am I making a good impression during this job interview? For most, such questions and concerns are a routine part of life. A new perspective paper from Brown University scientists establishes a framework to apply rigorous mathematical models of uncertainty originally developed for non-social situations, such as whether or not to purchase a lottery […]

Artificial intelligence predicts treatment effectiveness

How can a doctor predict the treatment outcome of an individual patient? Traditionally, the effectiveness of medical treatments is studied by randomised trials where patients are randomly divided into two groups: one of the groups is given treatment, and the other a placebo. Is this really the only reliable way to evaluate treatment effectiveness, or could something be done differently? […]
