Phys.org / Cast away: Tracing the voyage of a plastic bottle cap and its hitchhiking marine species
Researchers have traced the journey of a plastic bottle cap recovered near the waters of southern Japan by combining data from the label, chemical clues in tiny shells and ocean current simulations. They found 307 organisms, ...
Phys.org / When species are forced to move: Prediction models underestimate climate-related extinction risk
Climate change threatens many plant and animal species not only when their habitats disappear as climatic conditions change, but also when those habitats shift. In a new study, a team of University of Potsdam researchers ...
Phys.org / In Sicily, drones at work to predict volcanic eruptions
Hovering over the volcano, a buzzing drone pauses in front of a laser beam on the crater's edge as researchers test whether the devices can measure gases to predict eruptions.
Phys.org / Ribosome-based gene circuit lets cells read six signals and trigger responses
The molecular machinery that normally builds proteins inside cells has now taken on a new role as a "switch." A research team at POSTECH (Pohang University of Science and Technology) has developed a new 'RNA-based smart gene ...
Medical Xpress / Engineers develop AI tool to design peptides that turn signals on or off
To develop new and better peptides, the short amino acid strings behind medicines like GLP-1 drugs, researchers have used AI to generate candidates and to predict their properties.
Phys.org / Bacteria turn dissolved uranium into stable compound in 130 days, study finds
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), together with Wismut GmbH and scientists from the University of Granada in Spain, have demonstrated for the first time that bacteria can convert uranium dissolved ...
Phys.org / A robot that reads bacteria by touch, without staining or chemical labels
Fast identification of bacteria is important in health care, food safety, environmental monitoring and infection control. One of the most common first steps is gram classification, which separates bacteria into gram-positive ...
Medical Xpress / Brain glutamate changes could link cannabis use to a higher risk of psychosis
Cannabis, commonly known as marijuana, is a plant that contains psychoactive compounds that can temporarily alter people's brain activity and perceptions. While the consumption of this plant for medical or recreational purposes ...
Phys.org / Grasses provide most of the world's calories—but we're only now starting to learn how they grow
If we want to dismiss something as irrelevant, we'd say that it's "as boring as watching the grass grow." And yet grasses—including corn, wheat and rice—make up most of the plant-based calories humans eat, as well as most ...
Tech Xplore / Birdlike robot swims underwater, then flaps into flight without paddling
Loons, gulls, puffins and petrels are some of the 100 species of birds that can both fly and swim. These diving birds can plunge into water to swim after prey, and leap back into the air to fly away.
Medical Xpress / Artemisinin resistance is rising in East Africa—leaving anti-malarials at risk of failure
Resistance to the main drug in front-line malaria treatments is becoming more widespread across East Africa, according to new research by Imperial College London. The study, published in The Lancet Infectious Diseases, maps ...
Phys.org / The Vikings were more than bearded marauders, but Scandinavia's national museums continue to project that image
If you visit Scandinavia, you are likely to find yourself at an exhibition about Vikings. There are many to choose from.
