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 / 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 ...
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 ...
Phys.org / When the interaction between fungi and bacteria becomes a dangerous alliance
Rivals or allies—how do bacteria and fungi interact in our bodies? Until now, bacteria on our mucous membranes were primarily considered to be antagonists of fungi, as they can inhibit their growth. However, an international ...
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 / 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 ...
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 ...
Phys.org / Petra aqueduct survey uncovers rare 116-meter lead conduit beside terracotta pipe
In a recent study, Niklas Jungmann from the Humboldt-Universität zu Berlin conducted a survey and investigation of the 'Ain Braq aqueduct of the ancient city of Petra. It was discovered that, unlike previously believed, ...
Medical Xpress / Scientists now know why ovarian cancer spreads so rapidly in the abdomen
Ovarian cancer kills more women than any other gynecological cancer. Most patients receive their diagnosis only after the disease spreads throughout the abdomen. Until now, scientists have never fully understood why this ...
Tech Xplore / Stabilized iron catalyst could replace platinum in hydrogen fuel cells
Japan and California have embraced hydrogen fuel-cell technologies, a form of renewable energy that can be used in vehicles and for supplying clean energy to manufacturing sectors. But the technology remains expensive due ...
Medical Xpress / The body processes good fats and bad fats differently, study finds
The concept of "good fats" and "bad fats" has influenced diet trends, public health policy, and biomedical research for decades. Now, a new study led by Thomas A. Vallim, Ph.D., a researcher and professor of medicine in the ...
Phys.org / New 3D method maps Paleolithic engravings at submillimeter resolution
A team of archaeologists from the Universitat Jaume I, the University of Barcelona, and the Catalan Institution for Research and Advanced Studies (ICREA) has developed a new methodology that allows for a much more detailed, ...
