Tech Xplore / Erasable semiconductor is programmed with light
Researchers at Princeton Engineering have created a semiconductor with unique properties: It is just a few molecules thick and can repeatedly change its properties in response to light. This is a step toward building more ...
Phys.org / Mapping thorium's preferred sites could pave the way for nuclear clocks
For decades, physicists have used a technique called Mössbauer spectroscopy to peer inside solid materials, revealing fine details of their surroundings by studying how their atomic nuclei absorb and re-emit gamma rays.
Phys.org / Developing a genetic toolkit for manipulating abundant intestinal microbes
Weill Cornell Medicine investigators have developed a set of molecular tools to regulate the activity of specific genes in one of the most common classes of intestinal bacteria. The ability to genetically manipulate these ...
Phys.org / Exact calculations sharpen view of atomic nuclei
Every high-energy nuclear collision leaves behind a trail of clues about the structure of atomic nuclei. Deciphering those clues, however, depends on the accuracy of the underlying theory. Physicists at Osaka Metropolitan ...
Medical Xpress / Smart probiotics can sense high blood sugar and release GLP-1 on demand
For people living with diabetes, managing blood sugar can mean constantly watching the clock, keeping meals and medications on schedule and staying alert to changes in glucose levels. While little can be done about timed ...
Phys.org / Cowpea plants create underground defense system for the next generation after insect attacks
Plants might seem helpless when it comes to insect attacks, but they are known to employ various techniques to deter pests. One of these techniques involves sending out signals to recruit parasitoid wasps, and a new study, ...
Phys.org / Rare medieval manuscript fragments reveal Guernsey's lost literary history
Seventeen medieval manuscript fragments have been identified in Guernsey with support from Kent manuscript expert Dr. David Rundle, offering an unprecedented insight into the island's literary and intellectual life during ...
Phys.org / Electron beams cut poultry pathogens while preserving turkey quality
Researchers are gauging the effectiveness of electron beams in the fight against foodborne pathogens in poultry. "Impact of Electron Beam (eBeam) Treatment on Meat Quality and Sensory Attributes of Ground Chicken and Turkey" ...
Phys.org / Naked photobombing comet found in public image
Sometimes images are released before anyone realizes they have been photobombed, meaning something unexpected showed up in the background. A team of researchers found a naked photobombing comet in publicly available archival ...
Phys.org / Simulations reveal asymmetric diffusion of magnetic skyrmions through an off-center gate
Diffusion is a fundamental natural phenomenon that can be observed across a wide range of length and time scales. It plays a key role in many fields, including physics, biology and economics. In particular, asymmetric or ...
Phys.org / Forty forest drought experiments reveal trees show little physiological acclimation
Forests support much of the world's biodiversity and play a vital role in regulating Earth's climate, but they are increasingly exposed to drought. To understand the potential consequences of drought, a key question is whether ...
Phys.org / Expert pieces together puzzle from fragments of 1,600-year-old Roman text
A Roman law expert at the University of Cincinnati edited and translated a Latin legal text he pieced together from fragments that surprisingly survived in the Egyptian sands for more than 1,600 years. What's less surprising? ...
