Bob McDonald's blog: Humanity gets its first glimpse of what happens when an aging star overwhelms a close orbiting planet, just as our sun is expected to eventually do with Mercury, Venus and...
Newly developed 'smart' coatings for surgical orthopedic implants can monitor strain on the devices to provide early warning of implant failures while killing infection-causing bacteria, researchers report. The coatings integrate flexible sensors with a nanostructured antibacterial surface inspired by the wings of dragonflies and cicadas.
Cohen Irwin is part of a group of former addicts in New Zealand working with researchers to trace signs of healing in the brains of those who stop smokingEvery few months, Cohen “Coey” Irwin lies on his back and lets the walls close in. Lights move overhead, scanning over the tattoos covering his cheeks. He lies suspended, his head encased by a padded helmet, ears blocked, as his body is...
Scientists think the amulet absorbed DNA from contact with the skin of the person who wore it. That DNA tells them it was a woman related to people who lived across northern...
Stargazers in Asia and Australia had the best seats for the year's first lunar eclipse.
The U.S. federal government's management of wild horses is doomed to fail without fundamental changes in policy and the law, according to a new paper led by researchers at the University of Wyoming and Oklahoma State University.
Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. Since the days of Max Planck and Albert Einstein, we know that light as well as electricity are quantized, meaning they come in tiny packets called photons and electrons. In a solar cell, the energy of a single photon is transferred to a single electron of the material, but no more than one. Only a...
Microbiologists have uncovered the evolutionary origins of antimicrobial resistance (AMR) in bacteria. His studies on the bacterium that causes cholera, Vibrio cholerae, provide insight into deciphering what conditions must occur for infectious agents to become resistant. He studied genetic variants of a protein found in bacterial membranes called OmpU. Using computational and molecular...
Using a long-term multifactor experimental field site researchers showed that experimental warming of a tallgrass prairie ecosystem significantly altered the community structure of soil archaea and reduced their taxonomic and phylogenetic diversity.
Because contrasting societal views have created an approach that simultaneously manages horses on the range as wildlife, livestock and pets, current U.S. government programs are incapable of succeeding, according to researchers.
Researchers have proposed a new model for the evolution of higher brain functions and behaviors in the Hymenoptera order of insects. The team compared the Kenyon cells, a type of neuronal cell, in the mushroom bodies (a part of the insect brain involved in learning, memory and sensory integration) of 'primitive' sawflies and sophisticated honey bees. They found that three diverse, specialized...
Researchers have captured one of the fastest movements of a molecule called ferricyanide for the first time by combining two ultrafast X-ray spectroscopy techniques. They think their approach could help map more complex chemical reactions like oxygen transportation in blood cells or hydrogen production using artificial photosynthesis.
Providing defendants with legal counsel during their initial bail hearing decreases use of monetary bail and pretrial detention, without increasing the likelihood that defendants fail to appear at the subsequent preliminary hearing, according to a new RAND Corporation study.

Scientists at the Department of Genetics, Blavatnik Institute at Harvard Medical School have discovered something remarkable while studying phosphate transport in fruit fly intestines—a never before seen organelle. Their results are published in the journal Nature, and a News and Views piece in the same journal discusses their findings.

The High court dismisses case brought by animal activists against a government change in policy.
Brownfield restoration has become a frontier topic in the research on urban ecosystem governance. Optimizing brownfield ecosystems through proper bioremediation approaches can provide urban landscapes and habitats with sound ecological potentials. Currently, the lagging theory and technique development of brownfield vegetation restoration, the species selection based on single causality, and the...
A scientist will attempt to turn seismic activity—recorded in real time at Yellowstone National Park—into music during an ambitious live performance on Tuesday, May 9.
The Middle East and North African region lose about $13 billion a year because of increasing sand and dust storms. By combining learnings from artificial intelligence and 3000-year-old sustainable methods, researchers might be on the way to finding out how to mitigate the damages.
