Phys.org / Fragile no more, nickelates get an upgrade that changes how superconductivity endures
Discovered in 2019, the material known as nickelates has intrigued researchers for its potential to become a superconductor at elevated temperatures—a property that could significantly advance such fields as quantum science ...
Phys.org / How giants that vanished 10,000 years ago triggered ripple effects that are still felt today
Between 50,000 and 10,000 years ago, many of the world's largest mammals disappeared. Picture creatures like saber-toothed cats with 7-inch fangs and elephant-sized sloths. Woolly mammoths whose curved tusks grew longer than ...
Phys.org / Rivers worldwide reveal greenhouse gas rise that's been overlooked for decades
Rivers worldwide are under severe stress: they are warming, losing oxygen, and as a result emitting increasing amounts of greenhouse gases. Researchers at Karlsruhe Institute of Technology (KIT) have now quantified these ...
Tech Xplore / Motion-enhanced sensor captures ultra-high-resolution images, overcoming a pixel miniaturization bottleneck
Digital image sensors (DIS), devices that capture images by converting light patterns into electrical signals, are integrated in many contemporary electronic devices, including smartphones, digital cameras and some medical ...
Phys.org / Aligned cells may explain why some wounds heal faster than others
Understanding how wounds heal after injury could be a step closer thanks to a new mathematical model developed by researchers at the University of Bristol. The study, published in Physical Review Letters, builds on previous ...
Phys.org / Single X-ray photons reveal hidden light-matter interactions in 50-nanometer double slits
A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water droplets. This same physical effect underlies many everyday technologies, like LCD screens and broadband ...
Phys.org / Breaking connections helps ideas spread farther, says physics-based study
Sticking with the same people might feel safe and comfortable. But a new Northwestern University study suggests it can actually trap new ideas and behaviors inside tight echo chambers. By contrast, the research, published ...
Science X / Crows look plain black to us, but their feathers contain a secret visual code that changes with age
To understand birds—their social relationships, their choices, even their feathers—you need to understand the way they see the world. That can be a challenging task, because birds and humans literally see their environments ...
Medical Xpress / A new algorithm can spot who may be headed for self-harm before warning signs become obvious
Depression, one of the most widespread mental health disorders, is characterized by a persistent low mood and a loss of interest in everyday activities, along with possible sleep disruptions and/or changes in appetite. Some ...
Medical Xpress / Turning immune cells into tumor allies: A cancer cell protein can reprogram frontline defenders
Cancer cells can disarm the immune system not just by hiding from it, but by actively reprogramming nearby immune cells into a suppressed state. This previously unrecognized molecular interaction, discovered by scientists ...
Medical Xpress / Could a new tool for diabetes treatment be hiding in your spice cabinet?
Curcumin, the compound that gives turmeric its striking yellow hue, is known for its anti-inflammatory and antioxidant effects. A new study conducted in rats suggests it could also help ward off the cardiovascular damage ...
Phys.org / Why stars spin down, or up, before they die
From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they "spin down." The sun's total angular momentum has declined as material is gradually blown off at the surface ...
