COVID-19 often goes undiagnosed in hospital workers; virus may impair heart functions
A high proportion of COVID-19 infections among U.S. healthcare personnel appear to go undetected, according to a report on Monday in the Morbidity and Mortality Weekly Report of the U.S. Centers for Disease Control and Prevention. Between April and June, among more than 3,000 frontline workers in 12 states, roughly 1 in 20 had antibody evidence of a previous COVID-19 infection, but 69% of those...
Getting ahead isn't a nasty business, US study reveals
Researchers found ‘nice, generous’ people advanced at work just as much as bulliesThe question has puzzled humans from the earliest philosophers to the ranks of home workers who have swapped water cooler gossip for rants on Zoom: does being a jerk help people get to the top?Now, after a study lasting more than a decade, researchers believe they finally have the answer. Nasty colleagues are no...
Discovery of an ancient dog species may teach us about human vocalization
In a study published in PNAS, researchers used conservation biology and genomics to discover that the New Guinea singing dog, thought to be extinct for 50 years, still thrives. Scientists found that the ancestral dog population still stealthily wanders in the Highlands of New Guinea. This finding opens new doors for protecting a remarkable creature that can teach biologists about human vocal...
Scientists unlock crops' power to resist floods
Enzymes that control a plant's response to lower oxygen levels could be manipulated to make vital crops resistant to the impacts of flooding triggered by climate change, new research shows.
Stealing information from host plants: How the parasitic dodder plant flowers
About 4,000 to 5,000 parasitic plant species exist. Among these, dodders (Cuscuta, Convolvulaceae) are distributed worldwide. Compared with normal autotrophic plants, they have a unique morphology—they are rootless and leafless and carry out no or very little photosynthesis.
To the choir: Forward-thinking faculty sharing innovations mostly among themselves
Eager to learn the latest in instructional practices that research says will better engage and educate her students, an assistant professor of biochemistry attends a virtual workshop devoted to exactly that.
Climate change creating vast new glacial lakes, with risk of 'gargantuan' floods, researcher says
Meltwater from shrinking glaciers is creating vast lakes that could eventually pose an enormous flooding threat, says newly published...
Study finds missing link in the evolutionary history of carbon-fixing protein Rubisco
A team led by researchers at the University of California, Davis, has discovered a missing link in the evolution of photosynthesis and carbon fixation. Dating back more than 2.4 billion years, a newly discovered form of the plant enzyme rubisco could give new insight into plant evolution and breeding.
NASA's Suomi NPP satellite shows two views of California's smoky skies
NOAA/NASA's Suomi NPP satellite captured two images that tell the story about the smoke coming off the fires in California. One instrument on the provided a visible image of the smoke, while another analyzed the aerosol content within. The images were captured on August 30, 2020.
Leaked email reveals CVS instructed pharmacy staff not to tell patients their medications were filled by someone who tested positive for COVID-19
A CVS technician said the company threatened to fire staff if they told patients their medications were filled by a COVID-positive...
Trump eyes aquaculture boom, but environmentalists dig in
President Donald Trump wants to dramatically expand aquaculture production in the United States, but a coalition of environmentalists believes his plan would be bad for the oceans, unnecessary for food security and difficult to implement.

A study has found evidence for quantum fluctuations near a quantum critical point in a superconductor. Theory suggests that these quantum critical points may be analogous to black holes as places where all sorts of strange phenomena can exist in a quantum material.

Hydroacoustic 3-D snapshots of fish habitats could help stem overfishing
Robotic eyes and ears under the water's surface could help researchers figure out how much fish are in our oceans—and how much we can eat.
Researchers develop molecule to store solar energy
Researchers at Linköping University, Sweden, have developed a molecule that absorbs energy from sunlight and stores it in chemical bonds. A possible long-term use of the molecule is to capture solar energy efficiently and store it for later consumption. The current results have been published in the Journal of the American Chemical Society (JACS).
Researchers develop dustbuster for the moon
A team led by the University of Colorado Boulder is pioneering a new solution to the problem of spring cleaning on the moon: Why not zap away the grime using a beam of electrons?
Demonstrating the dynamics of electron-light interaction originating from first principle
With the highest possible spatial resolution of less than a millionth of a millimeter, electron microscopes make it possible to study the properties of materials at the atomic level and thus demonstrate the realm of quantum mechanics. Quantum-physical fundamentals can be studied particularly well by the interactions between electrons and photons. Excited with laser light, for example, the energy,...
Saving marine life: Novel method quantifies the effects of plastic on marine wildlife
Scientists at Tokyo Institute of Technology together with their international collaborators have developed a novel quantitative method to quantify the effects of plastic on marine animals. This method successfully shows that plastic ingestion by sea turtles might be causing population declines, despite a lack of strong effects on individual turtles.

New evidence for quantum fluctuations near a quantum critical point in a superconductor
Among all the curious states of matter that can coexist in a quantum material, jostling for preeminence as temperature, electron density and other factors change, some scientists think a particularly weird juxtaposition exists at a single intersection of factors, called the quantum critical point or QCP.
