Doctors can predict patients’ risk for ischemic stroke based on the severity of their metabolic syndrome, a conglomeration of conditions that includes high blood pressure, abnormal cholesterol levels and excess body fat around the abdomen and waist, a new study finds.

The study found that stroke risk increased consistently with metabolic syndrome severity even in patients without diabetes. Doctors can use this information — and a scoring tool developed by a UVA Children’s pediatrician and his collaborator at the University of Florida — to identify patients at risk and help them reduce that risk.

“We had previously shown that the severity of metabolic syndrome was linked to future coronary heart disease and type 2 diabetes,” said UVA’s Mark DeBoer, MD...

New design overcomes long-standing LED efficiency problem – and can transform into a laser to boot. A new design for light-emitting diodes (LEDs) developed by a team including scientists at the National Institute of Standards and Technology (NIST) may hold the key to overcoming a long-standing limitation in the light sources’ efficiency...

A special type of aurora, draped east-west across the night sky like a glowing pearl necklace, is helping scientists better understand the science of auroras and their powerful drivers out in space. Known as auroral beads, these lights often show up just before large auroral displays, which are caused by electrical storms in space called substorms...

Simple innovation expected to open multiple new avenues for quantum science. If we can harness it, quantum technology promises fantastic new possibilities. But first, scientists need to coax quantum systems to stay yoked for longer than a few millionths of a second.

A team of scientists at the University of Chicago’s Pritzker School of Molecular Engineering announced the discovery of a simple modification that allows quantum systems to stay operational – or “coherent” – 10,000 times longer than before...
