Medical Xpress / MRI supplemental to digital breast tomosynthesis averts additional breast cancer deaths
For women aged 40 years and older with extremely dense breasts, digital breast tomosynthesis (DBT) with supplemental magnetic resonance imaging (MRI) averts additional breast cancer deaths and results in more false-positive ...
Tech Xplore / Non-destructive battery testing with ultralow-field nuclear magnetic resonance
Rechargeable batteries are everywhere—from portable electronic devices and electric vehicles to renewable energy storage. Battery failures are often due to the loss or chemical degradation of the electrolyte.
Phys.org / Rainfall can shape bird populations as much as temperature, global study reveals
Scientists have long focused on rising temperatures to understand how climate change is reshaping the natural world. But there's a critical blind spot in that picture: rain. A new global study reveals precipitation has been ...
Phys.org / Lord of the fruit flies: How scientists are defending against a major agricultural pest
When Vasilis Rodovitis rips open his brown paper bag in a sunny persimmon orchard just outside Naousa, in Greece, I half expect groceries to spill out. Instead, a barely there gray cloud emerges. For half a week, the bag ...
Medical Xpress / Testosterone therapy could mean trouble for knee replacement patients, study warns
Testosterone therapy is booming in the U.S., but it might bring higher risks for people undergoing knee replacement surgery, a new study says.
Tech Xplore / Simulated cats and elephants with touch-based memory help usher in new age of robotics
A new approach to simulating biologically inspired robotics can cut the design and training of tactile robots from eighteen months to two weeks, new research suggests. Published in Cyborg & Bionic Systems, the study applies ...
Phys.org / NASA's eclipse megamovie project releases full data on 2024 solar eclipse
On April 8, 2024, people across the world witnessed a solar eclipse, a relatively rare event in which the moon occults (blocks out) light from the sun. To capture this event, volunteers at 143 observatories across the U.S. ...
Phys.org / From hyperbolic in-plane anisotropy to an optical chirality: A new route to nanoscale circular polarizers
In recent years, van der Waals crystals have evolved from scientific curiosities into a versatile platform for exploring novel quantum phases and unconventional nanophotonic phenomena. Their layered nature allows stacking, ...
Tech Xplore / Study proposes ways to control unforeseen leaks in underground excavations
A study involving the IIAMA Institute at the Universitat Politècnica de València (UPV) proposes a series of solutions to address a critical engineering problem: unforeseen water leaks during the construction of deep excavations. ...
Phys.org / BaSi₂-supported nickel catalyst boosts low-temperature hydrogen production
A new catalyst strategy developed at Institute of Science Tokyo uses BaSi2 as a support for nickel and cobalt to decompose ammonia at lower temperatures. By forming unique ternary transition metal–nitrogen–barium intermediates ...
Medical Xpress / Bacteria found in mouth and gut may help protect against severe peanut allergic reactions
One of the big mysteries in food allergy is why two people with similar levels of peanut-specific antibodies can react so differently. It turns out the answer may be in the mouth and gut's bacteria. A new study, led by researchers ...
Medical Xpress / New findings provide objective look at broad sensory impairments among long COVID sufferers
New research from The Ohio State University College of Medicine is the first to objectively measure multisensory losses in COVID-19 patients. "Our goal is to understand why some long COVID patients experience different profiles ...
