Millions of Americans have a blood test every year to measure LDL, often called “bad” cholesterol. But new research from Northwestern Medicine suggests that another test may do a better job of identifying who needs more aggressive treatment to reduce the risk of heart attacks and strokes. The study, published in JAMA, found that measuring…

Titan in ultraviolet and infrared wavelengths, as captured by the Cassini probe in 2004 NASA/JPL/Space Science Institute A strange substance is hiding on the surfaces of both Pluto and Saturn’s moon Titan, and researchers aren’t sure what it is. Titan’s thick atmosphere means it is extremely difficult to study its surface, so identifying this compound…

A thorough comparison of quantum and classical machine learning models has been undertaken by Chuanming Yu from Hebei Normal University, and colleagues at Kyushu University and the University of Luxembourg. The study compares seven model pairs across both supervised and reinforcement learning tasks. Findings reveal the evaluated quantum machine learning models do not currently exceed…

Astronomers have, for the first time, observed the birth of a magnetar, an extremely magnetic, rapidly spinning type of neutron star. The breakthrough confirms that these exotic objects can power some of the brightest stellar explosions ever seen. The discovery also validates a theory first proposed 16 years ago by a UC Berkeley physicist and…

Mink numbers in Kent could be cut by 90% within two years under a new project aimed at protecting wildlife. The Waterlife Recovery Trust (WRT) has received a £20,000 grant from the BASC Wildlife Fund to expand trapping and monitoring across Kent, which once had one of Britain’s highest densities of invasive American mink. Conservationists…
