Over the last decade, bariatric surgeons have made strides in performing weight loss surgery that not only reverses obesity but can also reverse type 2 diabetes in patients with both conditions. Despite dramatic improvements in quality of life and diabetes remission, the number of patients who pursue surgery remains relatively low, according to Ali Tavakkoli, MD, co-director of the Center for Weight Management and Metabolic Surgery at BWH...

Electrical dipole activity detected in a quantum material unlike any other tested. A theorized but never-before detected property of quantum matter has now been spotted in the lab, a team of scientists reports. The team proved that a particular quantum material can demonstrate electrical dipole fluctuations – irregular oscillations of tiny charged poles on the material – even in extremely cold conditions, in the neighborhood of -450 degrees Fahrenheit.

The material, first synthesized 20 years ago, is called k-(BEDT-TTF)2Hg(SCN)2 Br. It is derived from organic compounds, but behaves like a metal...

Recent GBT and ATCA observations have identified the telltale radio signal of diamond dust around 3 such stars, suggesting they are a source of the so-called anomalous microwave emission. Credit: S.

Nanoscale gemstones source of mysterious cosmic microwave light. Some of the tiniest diamonds in the universe – bits of crystalline carbon hundreds of thousands of times smaller than a grain of sand – have been detected swirling around 3 infant star systems in the Milky Way...

Using a pioneering method, researchers have found a neutron star of about 2.3 Solar masses – one of the most massive ever detected. Neutron stars (often called pulsars) are stellar remnants that have reached the end of their evolutionary life: they result from the death of a star of between 10 and 30 Solar masses. Despite their small size (about 20 km in diameter), neutron stars have more mass than the Sun, so they are extremely dense.

Researchers from the Universitat Politècnica de Catalunya (UPC) and the Canary Islands Institute of Astrophysics (IAC) used an innovative method to measure the mass of one of the heaviest neutron...
