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 / New screening system flags food-packaging chemicals linked to serious health risks
Packaged food usually sits in plastic-lined bags designed to keep air, moisture and contaminants out. That same protection can also increase the chances of chemicals from the packaging seeping into the food. When a chemical ...
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 ...
Medical Xpress / Where 9/11 responders live may influence frailty, PTSD and depression decades later
Twenty-five years after the September 11 terrorist attacks, researchers at the Icahn School of Medicine at Mount Sinai have found that environmental conditions where World Trade Center responders live may influence their ...
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 / 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 ...
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 / 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 / New insect genus and four species named for Taylor Swift and her albums
Taylor Swift is now the namesake of a genus of plant-feeding insects from Australia that were previously unknown to science.
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 / How big can the universe's first starbursts get?
As our telescopes have improved and we've been able to peer farther back in time, we've begun finding more fascinating features of the universe. But one thing we haven't found for sure is Population III (Pop III) stars. These ...
