Clinicians using a new viral screening test can not only diagnose COVID-19 in a matter of minutes with a portable, pocket-sized machine, but can also simultaneously test for other viruses -- like influenza -- that might be mistaken for the coronavirus. At the same time, they can sequence the virus, providing valuable information on the spread of COVID-19 mutations and variants.

A new study finds that antibody tests are able to predict prior COVID-19 infection, even for people with mild symptoms. Researchers also found that low-cost rapid screening methods, including finger prick tests, detect infection with nearly the same precision as higher-complexity lab tests.

Emerging technologies can screen for cervical cancer better than Pap smears and, if widely used, could save lives in areas where access to health care may be limited. In Biophysics Reviews, scientists at Massachusetts General Hospital write advances in nanotechnology and computer learning are among the technologies helping develop HPV screening that take the guesswork out of the precancer tests....

This 'metal-eating' robot can follow a metal path without using a computer or needing a battery. By wiring the power-supplying units to the wheels on the opposite side, the robot autonomously navigates towards aluminum surfaces and away from hazards that block its energy source.

At the same time the pandemic was expanding the number of people working remotely, children nationwide began attending school virtually. The result? An increase in domestic work that fell disproportionately on the shoulders of mothers, according to a new study by sociologists.

Almost six per cent of Ontarians online are spreading misinformation about the COVID-19 pandemic, according to exclusive new research conducted on behalf of the Ontario Medical...

A new invention that uses sunlight to drive water purification could help solve the problem of providing clean water off the grid.

Water quality management in the ocean often targets visible pollution sources such as sewage, rivers or ships. A new global study reveals that invisible groundwater discharges may be just as important driving nitrogen into coastal waters.

Researchers demonstrated a new method to detect freshwater plumes between the seafloor and ocean surface.

An international team of scientists led by Gina Moseley from the Department of Geology at the University of Innsbruck presents the very first analysis of sediments from a cave in northeast Greenland, that cover a time period between about 588,000 to 549,000 years ago. This interval was warmer and wetter than today, the cave deposits provide an outlook in a possible future warmer world due to...

The first imaging of substantial freshwater plumes west of Hawai'i Island may help water planners to optimize sustainable yields and aquifer storage calculations. University of Hawai'i at Mānoa researchers demonstrated a new method to detect freshwater plumes between the seafloor and ocean surface in a study recently published in Geophysical Research Letters.

It was Harlock's first day at coronavirus training school and she already showed promise.

Grizzly bears are slowly expanding the turf where they roam in parts of the northern Rocky Mountains but need continued protections, according to government scientists who concluded that no other areas of the country would be suitable for reintroducing the fearsome predators.

An enormous telescope complex in Tibet has captured the first evidence of ultrahigh-energy gamma rays spread across the Milky Way. The findings offer proof that undetected starry accelerators churn out cosmic rays, which have floated around our galaxy for millions of years. The research is to be published in the journal Physical Review Letters on Monday, April 5.

Downing Street sources reject reports the COP26 meeting in Glasgow will be postponed until next year.

Researchers found that female putty-nosed monkeys (Cercopithecus nictitans) use males as 'hired guns' to defend from predators such as leopards.

In order to remove heat, for example from computer chips, materials are needed which are extremely good at conducting heat. Scientists in Vienna have analyzed materials on an atomic level and found an excellent new heat conductor: theta-phase tantalum nitride.

A group of scientists have discovered a node in the brains of male mice that modulates the sounds they make in social situations. This discovery could help identify similar locations in the human brain, and potentially lead to a better understanding of social disorders.

Some cone snails use a previously undetected set of small molecules that mimic the effects of worm pheromones to drive marine worms into a sexual frenzy, making it easier to lure them out of their hiding places so the snails can gobble them up.

Researchers used NIST's agricomb to simultaneously measure emissions of methane, ammonia, carbon dioxide and water vapor from the atmosphere around a beef cattle feedlot in Kansas.

Scientists up to create the next version of Xenobots - tiny biological robots that self-assemble, carry out tasks, and can repair themselves. Now they can move faster, and record information.
