Phys.org / Researchers demonstrate organic crystal emitting red light from UV and green from near-infrared
Invisible light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and optical sensing. Ultraviolet and near-infrared wavelengths are routinely used in these fields, yet ...
Phys.org / The surprising power of a tiny, disordered protein in a mitochondrial supercomplex
For decades, scientists assumed that order drives efficiency. Yet in the bustling machinery of mitochondria—the organelles that crank out adenosine triphosphate (ATP), the universal "energy currency" of cells—one of the ...
Phys.org / Measuring time at the quantum level depends on material symmetry
EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the material. "The concept of time has troubled philosophers and physicists for thousands of years, and ...
Medical Xpress / One-third of dementia cases are linked to non brain-related diseases, study finds
Dementia is a term used to describe memory loss, impaired reasoning, difficulties communicating and other mental impairments that can be caused by Alzheimer's disease, other neurodegenerative disease, strokes, severe infections, ...
Phys.org / Astronomers trace a runaway star to a former companion's supernova
Astronomers have strengthened long-standing predictions that massive runaway stars could have originated in binary pairs, and were dramatically ejected into space when their companion stars underwent supernova explosions. ...
Medical Xpress / Experimental bioadhesive patch sticks to wet brain tissue and wipes out most glioblastoma cells
Glioblastoma is the most prevalent and aggressive brain tumor. It proliferates very rapidly, is highly invasive, and there is currently no treatment capable of halting its progression or curing it, which means life expectancy ...
Tech Xplore / Is artificial general intelligence already here? A new case that today's LLMs meet key tests
Will artificial intelligence ever be able to reason, learn, and solve problems at levels comparable to humans? Experts at the University of California San Diego believe the answer is yes—and that such artificial general ...
Phys.org / School breaks make up more than an hour of the day. Should they be considered part of learning?
Most public debate about schooling focuses on what happens inside the classroom—on lessons, tests and academic results.
Phys.org / Aerobic respiration began hundreds of millions of years earlier than previously thought, study suggests
Oxygen is a vital and constant presence on Earth today. But that hasn't always been the case. It wasn't until around 2.3 billion years ago that oxygen became a permanent fixture in the atmosphere, during a pivotal period ...
Phys.org / Broken inversion symmetry lets 3D crystals mimic 2D Ising superconductivity
Two-dimensional (2D) materials, in general, allow the realization of unique quantum phenomena unattainable in the common three-dimensional (3D) world. A prime example is graphene. Transition metal dichalcogenides (TMDs) have ...
Phys.org / Artificial light is reshaping caracal behavior, limiting where the South African wild cat can hunt
Artificial light is one of the most ingrained features of modern life. For humans, light after dark offers convenience and a sense of safety. For wildlife, it's a growing environmental disturbance. "When humans introduce ...
Medical Xpress / Addiction and appetite along the gut-brain axis: Vagus nerve may play a crucial role in the dopamine reward pathway
Dopamine—a neurotransmitter responsible for influencing motivation, pleasure, mood and learning in the brain—has experienced a bit of fame in recent years, acting as a sort of buzzword to describe a fleeting satisfaction ...
