After 15 years, pulsar timing yields evidence of cosmic background gravitational waves

Groups report evidence that the cosmos is filled with a background of gravitational waves likely due to mergers of supermassive black hole binaries. The universe is humming with gravitational radiation…

Hospital pathogen Acinetobacter baumannii

… quickly adapts to new environmental conditions. Hospital-acquired infections are often hard to treat because the corresponding pathogens become increasingly resistant against antibiotics. Here, the bacterium Acinetobacter baumannii is particularly…

Earth’s most ancient impact craters are disappearing

Earth’s earliest history still holds mysteries for geologists, and ancient craters could provide some answers — scientists are racing against time to find them. Earth’s oldest craters could give scientists…

How atomic nuclei vibrate

Using ultra-high-precision laser spectroscopy on a simple molecule, a group of physicists led by Professor Stephan Schiller Ph.D. from Heinrich Heine University Düsseldorf (HHU) has measured the wave-like vibration of…

Machine learning: artificial neural networks localize extrasystoles

KIT researchers use deep learning for non-invasive localization of ventricular extrasystoles. Worldwide, cardiovascular diseases cause more than 17 million deaths per year. Of these, about 25 percent are deemed sudden…

Successful structure search

Construction of Monoatomic Lead Layers with Specially Developed Method Unveiled for the First Time. Research team led by Chemnitz University of Technology synthesizes two-dimensional layer of lead using a novel…
