Phys.org / Gold nanoclusters could help break down Alzheimer's amyloid plaques
Alzheimer's disease is a neurodegenerative brain disorder characterized by progressive memory loss and a decline in other mental functions. Past studies have consistently linked this disorder to the accumulation of the protein ...
Phys.org / Immune cells have a 'sense of touch,' scientists discover
Scientists have long believed that tissue-resident memory T cells—which remain in tissues after an infection has cleared and respond rapidly if the threat returns—are shaped primarily by biochemical signals. A McGill University–led ...
Phys.org / Last common ancestor of humans and chimpanzees could have been a vertical climber, no matter its feet
New research suggests that no matter what we eventually determine the last common ancestor of humans and chimpanzees to be, we'll learn it was a primate that climbed trees.
Phys.org / Physicists predict a new form of quantum matter that holds itself together
Researchers at Monash University have predicted a new type of quantum matter that challenges decades of thinking about how ultracold particles behave. The paper, "Quantum droplets in a resonant Bose-Fermi mixture," is published ...
Phys.org / Unlocking Gondwana's 120-million-year archive: Karoo record refines timing of extinctions and climate upheavals
A new review led by professor Emese Bordy at the University of Cape Town (UCT) Department of Geological Sciences brings together more than two decades of research on the Karoo Supergroup, revealing how scientific understanding ...
Phys.org / Three photons at once beat the standard photon test
Physicists at the University of Twente have improved the standard test for the quality of individual particles of light. By letting three photons interfere at the same time instead of two, they draw more information from ...
Phys.org / Quantum light engine links atom-photon thermodynamics to classical physics
What is heat, and what is useful work if a machine consists only of an atom and light particles? In modern quantum technologies, this kind of question connects thermodynamics with quantum physics. Researchers at the University ...
Phys.org / A weakening Atlantic Ocean current system could accelerate Earth's warming
A current system in the Atlantic Ocean that shapes regional climates and distributes ocean nutrients also serves as a control knob to help regulate temperatures across the planet, new research has found.
Phys.org / How ancient trees are warning us about the next enormous solar storm
Our sun is capable of storms far bigger than we've ever recorded. Studying the world's oldest trees suggests we could soon be due one of these gargantuan events.
Phys.org / Labrador Sea a key player in providing oxygen for deep North Atlantic life
Researchers from Cornell University have pinpointed the source of oxygen that sustains deep-sea life in the North Atlantic Ocean: the churning waters in the Labrador Sea.
Phys.org / Time-gating technique sees through deep tissue, dense fog, and other obstacles
From helping doctors detect cancer to guiding self-driving cars through traffic, many modern imaging systems rely on near-infrared light, producing a crisp picture when visible light would scatter and yield a blurry picture. ...
Phys.org / Who's watching who? Otters turn their attention to humans
For many people, a trip to the zoo is a chance to watch playful otters dart through the water and chatter with one another. But while we may worry that crowds could stress the otter community, a new Australian study shows ...
