Phys.org / A wandering black hole caught feeding on the run
Astronomers have found the first direct evidence that a wandering black hole can feed itself by dragging gas along in its wake as it moves through its galaxy. It's the first direct evidence of an accretion channel long predicted ...
Medical Xpress / Iron overload: How tea, coffee, red meat and alcohol can affect absorption
Most of us are used to hearing about the risks of not getting enough iron. Yet having too much iron in the body can also cause serious health problems.
Phys.org / Mosquito 'toilet' detects West Nile and first Hedwig-like virus found in the Americas
When public health researchers want to know whether diseases such as COVID-19 or polio are circulating in a community, they can look for genetic evidence in wastewater.
Phys.org / New analysis reconstructs the dawn of dinosaurs and other reptiles
About 252 million years ago, at the end of the Permian Period, a large proportion of species on Earth rapidly became extinct. After this mass extinction, many groups of organisms began to recover, while reptiles known as ...
Phys.org / Blue light breaks long-standing chemistry rule, unlocking 3D drug building blocks
For more than a century, pharmaceutical companies have relied on flat structures called aromatic rings, which can help drugs bind to target sites in the body. They include benzene rings and other flat, nitrogen-containing ...
Phys.org / Europe's e‑waste is a valuable resource—let's not throw it away
Throwing something away that is urgently needed, expensive and difficult to source sounds crazy. Yet of the 60 metals contained in old electronic devices such as phones, screens and washing machines, only a few are recycled. ...
Tech Xplore / Humanoid robot learns to sprint and perform spin kicks using AI trained on human motion data
Humanoid robots, robotic systems with body shapes and limbs resembling those of humans, could potentially assist people with manual tasks in various real-world settings. So far, however, most of these robots can reliably ...
Phys.org / Could the clues to ancient alien civilizations be hiding in moon dust?
Most of our experience with the Search for Extraterrestrial Intelligence (SETI) has focused on capturing radio signals that alien species have sent out, whether intentionally or unintentionally. That creates a huge "synchronicity" ...
Medical Xpress / Smartphone-controlled microneedle patch could offer drug-free pain care from afar
A "wearable electroceutical" has been developed that could reduce the need to visit a hospital or rely on painkillers every time pain occurs. When attached to the skin, it modulates pain through electrical stimulation and ...
Tech Xplore / Improved thin film harnesses indoor light to power devices
Remember the solar calculator from middle school math class that had a small solar cell at the top? The idea behind that technology is not a relic of the past but the subject of continuous innovation. Today's indoor solar ...
Phys.org / Evolutionary home advantage: Field experiment reveals adaptation to be surprisingly local
A research team from the University of Bern has shown in a large-scale field experiment that populations of the same fish species can be much more fine-tuned to their local environments than previously thought. Habitats that ...
Phys.org / Frontline safety concerns mount among property managers, new survey shows
Safety and security challenges are creating unprecedented strain for frontline property management professionals, according to a new bilingual survey conducted by Portland State University's Center for Real Estate. Initiated ...
