Phys.org / Scientists take a step toward a quantum internet using New York City's fiber
As long as there's been an internet, there's been a way to hack it. Scientists have spent decades imagining a different kind of network, one where the laws of physics make eavesdropping physically impossible, not just technically ...
Phys.org / US climate sees decline in both hot and cold extreme temperatures since 1899, researchers claim
A comprehensive new study extending the U.S. Historical Climatology Network (USHCN) record back to 1899 finds that both hot and cold temperature extremes across the contiguous United States have declined over the past 127 ...
Phys.org / Breakthrough sulfur polymer kills dangerous fungi and bacteria while sparing human and plant cells
Antimicrobial resistance is becoming a global burden in human health and food production, so affordable new materials are needed to overcome this growing problem. To answer the call, a multidisciplinary research team led ...
Phys.org / Cell membranes may store memories after electrical stimulation
The science of memories has been pursued and studied since the days of ancient Greece and Aristotle. Today, research conducted by Dima Bolmatov, assistant professor in the Department of Physics & Astronomy at Texas Tech University, ...
Phys.org / A few extra minutes of daily play can strengthen your bond with your dog in four weeks
Playing a little extra with your dog improves the emotional bond between owner and dog, according to a new study from Linköping University. However, training did not give the same results. The study is relevant for all dog ...
Phys.org / Collagen analysis finds wider prey use by Neanderthals and modern humans
The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) has taken part in a study published in the International Journal of Osteoarchaeology that provides new insights into subsistence strategies during the ...
Phys.org / Pressure-tuned quantum spin liquid-like behavior observed in material Y-kapellasite
A quantum spin liquid is a phase of matter in which the magnetic moments in a material do not align or freeze, even at temperatures close to absolute zero (i.e., at 0 K). The experimental realization of this highly dynamic ...
Phys.org / Before the melt begins, sea stars show hidden immune collapse and tissue failure driving a coastal die-off
Scientists are homing in on a mysterious wasting disease that has killed billions of sea stars along the Pacific coast of North America since 2013. Sea star wasting disease can rapidly wipe out entire populations, leaving ...
Phys.org / Half of America sits in democratic limbo—and that silent middle may decide what breaks next
If you were to ask democracy scholars what they consider the greatest threat to American democracy, you might assume it is voters who support undemocratic practices or policies. But the real answer may surprise you: These ...
Medical Xpress / A common weed killer left a hidden epigenetic footprint in early-onset colon cancer
A study led by José A. Seoane, Head of the Vall d'Hebron Institute of Oncology's (VHIO) Computational Biology Group identifies for the first time the exposome footprint—the set of environmental and lifestyle exposures—in ...
Medical Xpress / Why electroconvulsive therapy remains contested: Families report memory loss, worse quality of life and limited benefits
Electroconvulsive therapy (ECT), which involves passing electricity through the brain under general anesthesia to cause a seizure, usually between six and 12 times, is used to varying degrees around the world for patients ...
Phys.org / Penguin muscle map reveals how waddles and underwater 'flight' both work
Penguins may look charmingly awkward on land, but new research shows their bodies are finely tuned for powerful, efficient movement both on land and underwater. A team of anatomists from Midwestern University, in collaboration ...
