Fast, portable test can diagnose COVID-19 and track variants
- ScienceDaily
- 21/3/31 23:37
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.
COVID-19 antibody tests, even rapid finger pricks, are effective, new study finds
- ScienceDaily
- 21/3/31 23:37
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.
Cervical cancer testing tech could replace pap smears, save lives
- ScienceDaily
- 21/3/31 23:37
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....
Even without a brain, metal-eating robots can search for food
- ScienceDaily
- 21/3/31 23:37
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.
Mothers bear the cost of the pandemic shift to remote work
- ScienceDaily
- 21/3/31 23:37
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.
Older Ontarians most involved in online spread of COVID-19 myths, study finds
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...
Low-cost solar-powered water filter removes lead, other contaminants
A new invention that uses sunlight to drive water purification could help solve the problem of providing clean water off the grid.
Groundwater discharge affects water quality in coastal waters
- ScienceDaily
- 21/3/31 21:37
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.
Greenland caves: Time travel to a warm Arctic
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...
First images of freshwater plumes at sea
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.
Italian dogs sniff through COVID-19 bootcamp
It was Harlock's first day at coronavirus training school and she already showed promise.
Scientists: Grizzlies expand turf but still need protection
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.
Decades of hunting detects footprint of cosmic ray superaccelerators in our galaxy
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.
COP26: Government has 'no plans' to delay climate summit
Downing Street sources reject reports the COP26 meeting in Glasgow will be postponed until next year.
Female monkeys use males as 'hired guns' for defense against predators

Researchers found that female putty-nosed monkeys (Cercopithecus nictitans) use males as 'hired guns' to defend from predators such as leopards.
Heat conduction record with tantalum nitride
- ScienceDaily
- 21/3/31 20:31
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.
Newly discovered node in brain could expand understanding of dysfunctional social behavior
- ScienceDaily
- 21/3/31 20:31
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.
Cone snails use sexual enticements to lure prey out of hiding
- ScienceDaily
- 21/3/31 20:31
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.
