Phys.org / The changing chemistry of invasive death cap mushrooms
The California Department of Public Health reported 39 related poisonings in the last three months, leading to the death of four people, at least three liver transplants, and many more people made sick. The culprit? In each ...
Phys.org / Saturn's moon Titan could have formed in a merger of two old moons
Recent research suggests that Saturn's bright rings and its largest moon, Titan, may have both originated in collisions among its moons. While Cassini's 13-year mission expanded our understanding of Saturn, the discoveries ...
Phys.org / Silicon metasurfaces boost optical image processing with passive intensity-based filtering
Of the many feats achieved by artificial intelligence (AI), the ability to process images quickly and accurately has had an especially impressive impact on science and technology. Now, researchers in the McKelvey School of ...
Tech Xplore / 'Dynamic plastic delocalization' can slow metal alloy cracking, engineers find
Metal alloys crack and fail through a mechanism called "fatigue" when repeatedly loaded and strained. While it is well known how to design alloys to withstand static loads and pressures, it is very difficult to design resistance ...
Phys.org / Rich medieval Christians bought graves 'closer to God' despite leprosy stigma, archaeologists find
Medieval Christians in Denmark showed off their wealth in death by buying prestigious graves: the closer to the church, the higher the price. Researchers used these gravesites to investigate social exclusion based on illness, ...
Phys.org / Satellite observations put stratospheric methane loss higher than models predicted
Methane is a powerful greenhouse gas with strong heat-trapping capabilities. Although there is less methane in the atmosphere than carbon dioxide, the foremost greenhouse gas, researchers attribute 30% of modern global warming ...
Phys.org / Nanolaser on a chip could cut computer energy use in half
Researchers at DTU have developed a nanolaser that could be the key to much faster and much more energy-efficient computers, phones, and data centers. The technology offers the prospect of thousands of the new lasers being ...
Medical Xpress / Scientists create 'smart underwear' to measure human flatulence
Scientists at the University of Maryland have created Smart Underwear, the first wearable device designed to measure human flatulence. By tracking hydrogen in flatus, the device helps scientists revisit long-standing assumptions ...
Medical Xpress / Study identifies a new class of drug targets for aggressive leukemia
Hyperactive signaling pathways of some aggressive blood cancer cells can be tamped down by a previously unrecognized protein complex, ensuring the cancer's survival. If one component of the complex is deleted or removed, ...
Phys.org / How giant galaxies could form just 1.4 billion years after the Big Bang
The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international team led by Nikolaus Sulzenauer and Axel Weiß from the Max Planck Institute for Radio Astronomy ...
Phys.org / Oldest known reptile skin impressions dated to 298 million years found in Germany
An international research team led by Dr. Lorenzo Marchetti from the Museum für Naturkunde Berlin has described the oldest known impressions of reptile skin from the Thuringian Forest in central Germany. Particularly remarkable ...
Tech Xplore / A forgotten battery design from Thomas Edison—how scientists helped reimagine it
A little-known fact: In the year 1900, electric cars outnumbered gas-powered ones on the American road. The lead-acid auto battery of the time, courtesy of Thomas Edison, was expensive and had a range of only about 30 miles. ...
