Phys.org / Shorter front-leg strides can be an early warning sign of dementia in senior dogs
Scientists have shown that the stride length of the front legs (but not the hind legs) of senior and geriatric dogs decreases as their cognitive performance worsens. In contrast, chronological age itself was a poor predictor ...
Phys.org / Laser experiments push helium to record shock pressures
Deep inside gas giants like Jupiter and Saturn, hydrogen and helium coexist under pressures millions of times greater than Earth's atmosphere. Under those conditions, helium may separate from hydrogen and influence a planet's ...
Tech Xplore / A new type of pixel can steer and analyze light, paving way for devices that function as both camera and display
In 1927, the term "picture element," later abbreviated to "pixel," appeared for the first time in the American technology magazine Wireless World. Today, pixels are everywhere: in computer screens and television sets, where ...
Phys.org / How long can plants survive on Earth? New model suggests up to 2 billion more years
Vegetarians need not worry yet—plants will be on Earth for a long time to come. But not forever. The sun will ultimately determine the long-term existence of life on Earth. Its total energy output, called luminosity, has ...
Phys.org / Sugar-coated nanoparticles show promise for treating most aggressive form of brain cancer
Researchers at Oregon State University have potentially found a new way to treat the most aggressive form of brain cancer, glioblastoma, whose two-year survival rate is less than 30%.
Tech Xplore / Brain-inspired AI architecture could compute faster while using far less power
Spiking neural networks (SNNs) are artificial intelligence (AI) models inspired by how biological neurons communicate with each other. While biological neurons exchange information in the form of electrical impulses, SNNs ...
Medical Xpress / Hope for spinal injuries as pigs walk again after experimental gel treatment for severed spinal cords
In humans and other mammals, spinal cord injuries can be devastating, leading to permanent loss of movement, sensation and bladder control. When severed axons (the long fibers that carry messages between nerve cells) cannot ...
Medical Xpress / New oral GLP-1 drug delivers up to 12% weight loss in 36 weeks
A new strategy for delivering GLP-1 drugs to patients with obesity or who were overweight resulted in up to a 12% reduction in body weight after 36 weeks, according to a randomized phase II clinical trial published in Nature ...
Phys.org / Euclid mission view of Milky Way's heart previews upcoming survey by NASA's Roman
A new look at the heart of our Milky Way galaxy by Euclid, an ESA (European Space Agency) mission with NASA contributions, overlaps with a region scientists will observe with NASA's Nancy Grace Roman Space Telescope, launching ...
Phys.org / First complete map of world's seagrass offers warnings and hope for conservation
It's time we gave seagrass the credit it's due. This hero of a plant protects coastlines, stores vast amounts of carbon and supports ecosystems that people and wildlife depend on. But we don't often hear about it when it ...
Phys.org / From virtue to vice: How the morality of popular music lyrics has changed since the 1960s
Popular music may be reflecting a growing culture of vices, according to new research from the Center for Digital Music at Queen Mary University of London. The analysis of musical evolution found that song lyrics have become ...
Phys.org / A magnetic field that kills superconductivity can also bring it back
Magnetic fields are generally known to destroy superconductivity in a material. However, in exceptional cases, they can lead to what is known as "re-entrant superconductivity"—where superconductivity disappears as expected, ...
