Phys.org / How the humble silkworm could help us discover new anti-aging treatments
When scientists want to study aging and how to slow it down, they often turn to microscopic worms or lab mice among other models. The former are too different from humans, while the latter are expensive and take too long ...
Phys.org / Measuring chaos: Researchers quantify the quantum butterfly effect
For the first time, researchers in China have accurately quantified how chaos increases in a quantum many-body system as it evolves over time. Combining experiments and theory, a team led by Yu-Chen Li at the University of ...
Phys.org / The Princess of Bagicz: Dendrochronology settles debate over age of rare Roman-era wooden coffin
Dr. Marta Chmiel-Chrzanowska and her colleagues conducted a multidisciplinary analysis of the only known preserved wooden coffin from the Roman Iron Age, the Princess of Bagicz. The study, published in Archaeometry, used ...
Phys.org / The cooling system that lets bees beat the heat when hovering
To stay in the air when hovering over a flower, bumble bees continually flap their wings rapidly, a metabolic process that generates a massive amount of internal heat. Their flight muscles work so intensely that they can ...
Phys.org / Sudan's historic acacia forest devastated as war fuels logging
Vast stretches of a once-verdant acacia forest south of Sudan's capital Khartoum have been reduced to little more than fields of stumps as nearly three years of conflict have fueled deforestation.
Phys.org / Araish spiral galaxy observations uncover a 26,700-light-year radio jet
An international team of astronomers has performed multi-wavelength observations of the nearby Araish galaxy to investigate the origin of its radio emission. As a result, they detected an extended radio jet of this galaxy. ...
Phys.org / Ultra-stable lasers that rely on crystalline mirrors could advance next-generation clocks and navigation
Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e., systems that can keep ...
Phys.org / Exposing a hidden anchor for HIV replication
The tiny shell protecting the HIV virus resembles a slightly rounded ice cream cone, but there is nothing sweet about it. More than 40 million people worldwide live with AIDS because of this virus, and treatments must continually ...
Medical Xpress / Recurrent prostate cancer: Two treatment strategies with uncertain outcomes compared
Imperial College London investigators compared focal therapy with prostate removal surgery for men with prostate cancer that returned after radiotherapy. Matched analyses estimated 10-year cancer-specific survival at 92% ...
Phys.org / Cosmic predators: How supermassive black holes slow star growth in nearby galaxies
Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies millions of light-years ...
Medical Xpress / Scientists discover 'bacterial constipation,' a new disease caused by gut-drying bacteria
Scientists at Nagoya University in Japan have found two gut bacteria working together that contribute to chronic constipation. The duo, Akkermansia muciniphila and Bacteroides thetaiotaomicron, destroy the intestinal mucus ...
Phys.org / Antarctic warming is altering atmospheric stability: New evidence from the 1950s to the present
A new study published in the Journal of Climate reveals how surface warming in Antarctica, particularly over the Antarctic Peninsula, is significantly altering the stability of the lowest layers of the atmosphere.
