Phys.org / Psychologist wins Ig Nobel for proving rich drivers are the worst
Paul K. Piff, UC Irvine associate professor of psychology, has officially been recognized for what millions of frustrated commuters have long suspected: The fancier the car, the worse the driver.
Phys.org / Ultra-cold quantum sensors cut X-ray uncertainty, improving nuclear material assessments
To monitor the amount and type of nuclear material at power plants and weapons facilities, scientists look for a special signal—the unique pattern of gamma rays emitted by specific radioactive elements. However, some of these ...
Phys.org / Unaccounted climate feedback loops may amplify warming by 20–30% this century, but cutting emissions will reduce risks
New research shows that warming-induced emissions—greenhouse gas emissions from natural sources driven by rising temperatures—could amplify global warming by approximately 20%–30% and add an estimated 0.2°C–0.4°C of warming ...
Phys.org / 'Peculiar' new species of Jurassic squid found in Wyoming
A "peculiar" new species of Jurassic squid-like animal has been unearthed in Wyoming, U.S., following the discovery of two exceptionally rare fossils dating to around 160 million years ago.
Phys.org / Cell wall transport disruption exposes weakness in antibiotic-resistant bacteria
Even highly antibiotic-resistant bacteria become more vulnerable when their cell wall transport system is disrupted, according to a new study from Umeå University. The discovery reveals a previously overlooked weakness that ...
Phys.org / A fake spider at the tip of this snake's tail helps it lure birds: Scientists get their first look inside it
Lots of animals use mimicry to survive. Some copy the appearance of threatening predators, and others have evolved to resemble plants or rocks so they can blend into the background and avoid being attacked. But a viper from ...
Phys.org / An unusual bacterium that penetrates and lives inside human cells may offer a new drug target
Research underway in the lab of Rebecca Alexander, a professor in Wake Forest University's Department of Chemistry, is shedding light on an unusual human bacterium, Mycoplasma penetrans. Alexander's work to understand how ...
Phys.org / Tightly guided atoms could enable low-power quantum navigation when GPS fails
Within tiny halos of light clinging to a vanishingly thin wisp of optical fiber, scientist Jongmin Lee guides atoms like marbles through a narrow pipe. Rock the fiber and the atoms shift side by side; they just don't fall ...
Phys.org / Ultrathin silicon structures can tune mid-IR light in billionths of a second
Light in the mid-infrared (mid-IR) portion of the electromagnetic spectrum plays a key role in modern sensing. Because molecules interact with this kind of light in specific ways, researchers use technologies like mid-IR ...
Phys.org / Chinese cave traces Denisovan hunting and adaptation across 120,000 years
An ancient cave in southwestern China has revealed new evidence about how Denisovans—an ancient human relative—lived, survived and adapted over more than 100,000 years.
Phys.org / Unveiling how nanoparticles create iridescence in ancient ceramics
Scientists led by the Universitat Politècnica de Barcelona and the ESRF, the European Synchrotron, have revealed the chemical reactions in nanoparticles that created a unique, shimmering effect in the painting on ninth-century ...
Phys.org / Global database reveals why no two cities' food emissions look the same
Switching to a more sustainable diet could halve food-related emissions in cities such as Amsterdam, while in cities such as Dhaka and Delhi, the focus should be more on making food production more sustainable as they widen ...
