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. […]

Novel school improvement program can raise teaching quality while reducing inequality

A multi-national European study, looking at over 5,500 students, has found that a novel school intervention program can not only improve the mathematics scores of primary school children from disadvantaged areas, but can also lessen the achievement gap caused by socioeconomic status. Known as the Dynamic Approach to School Improvement (DASI), the program is based on the latest findings in […]

Half a face enough for recognition technology: Researchers achieve 100 percent recognition rates for half and three-quarter faces

Facial recognition technology works even when only half a face is visible, researchers from the University of Bradford have found. Using artificial intelligence techniques, the team achieved 100 per cent recognition rates for both three-quarter and half faces. The study, published in Future Generation Computer Systems, is the first to use machine learning to test the recognition rates for different […]

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 […]

Mathematicians reveal secret to human sperm’s swimming prowess

Researchers have discovered what gives human sperm the strength to succeed in the race to fertilise the egg. The researchers, from the universities of York and Oxford, discovered that a reinforcing outer-layer which coats the tails of human sperm is what gives them the strength to make the powerful rhythmic strokes needed to break through the cervical mucus barrier. Only […]

Artificial intelligence cuts lung cancer screening false positives

Lung cancer is the leading cause of cancer deaths worldwide. Screening is key for early detection and increased survival, but the current method has a 96 percent false positive rate. Using machine learning, researchers at the University of Pittsburgh and UPMC Hillman Cancer Center have found a way to substantially reduce false positives without missing a single case of cancer. […]
