Phys.org / Ultrasound waves rupture COVID-19 and flu viruses without damaging cells
Researchers at the University of São Paulo (USP) in Brazil have discovered that high-frequency ultrasound waves similar to those used in medical exams can eliminate viruses such as SARS-CoV-2 and H1N1 without damaging human ...
Phys.org / Photonics advance could enable compact, high-performance lidar sensors
Lidar systems use pulses of infrared light to measure distance and map a 3D scene with high resolution, allowing autonomous vehicles to rapidly react to obstacles that appear in their path. But traditional lidar sensors are ...
Phys.org / From pantry to pest control: Garlic kills the mood for mosquitoes as well
Garlic is not a substance that most people consider an aphrodisiac. It turns out that mosquitoes agree. In fact, a new Yale study finds that garlic also functions as a de facto birth control for mosquitoes and other winged ...
Phys.org / These monster black holes did not form the usual way—their history of violence is written into spacetime ripples
The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from collapsing stars, according to a new study. These cosmic giants instead build up through a series of ...
Phys.org / Quantum metallurgy: Electron crystals deform and melt
In a process analogous to how solids melt into liquids, the electrons in many different metals form crystal-like patterns that can deform and melt, opening new pathways for neuromorphic computing and superconductors, University ...
Phys.org / Researchers combine five metals to build a better nanocrystal
A nanocrystal is an extraordinarily tiny piece of material—composed of anywhere from a few to a few thousand atoms—in which atoms are arranged in a precise, ordered structure. Think of it like taking a piece of gold and shrinking ...
Phys.org / Archaeologists unearth evidence of dogs being traded within Mayan societies
A University of Calgary archaeologist has found evidence that the Classic Period Maya were trading live dogs over long distances between the northern Yucatan peninsula and central Chiapas regions.
Phys.org / Myanmar's devastating quake could reshape how California and other fault zones gauge future risk
A devastating earthquake in Myanmar is giving scientists new insight into how major quakes start, spread, and grow. The findings could improve risk estimates for dangerous faults around the world. A new study, published in ...
Phys.org / Team steers electron spin ballistically in graphene
Researchers at The University of Manchester's National Graphene Institute have shown that electrons in ultra-clean graphene can be steered with high precision while keeping their spin information intact, a key requirement ...
Phys.org / Chilean wasp named in honor of Sir David Attenborough's 100th birthday
Scientists from the Natural History Museum, London have described a new genus and species of parasitic wasp found within the Museum's collections, and named it as a birthday present for Sir David Attenborough.
Phys.org / LED light unlocks 3D optical fingerprints inside materials without lasers
Researchers have developed, for the first time in the world, incoherent dielectric tensor tomography (iDTT), a technology that can read complex three-dimensional optical fingerprints inside materials using only everyday LED ...
Phys.org / Mechanical method unlocks sunlight-driven wastewater cleanup
University of Birmingham researchers have demonstrated a new method to break down toxic pollutants in wastewater, using sunlight and molecular-thin catalysts created using an innovative "mechanical" approach. Non-degradable ...
