Modernize scope of practice for health-care professionals, researchers say

Around the country, the collective voice of eight directors of health workforce research centers came together to call for a reforming of laws and regulations that limit the practice of health professionals.

Preclinical study links human gene variant to THC reward in adolescent females

A common variation in a human gene that affects the brain's reward processing circuit increases vulnerability to the rewarding effects of the main psychoactive ingredient of cannabis in adolescent females, but not males, according to preclinical research by Weill Cornell Medicine investigators. As adolescence represents a highly sensitive period of brain development with the highest risk for initiating cannabis use, these findings in mice have important implications for understanding the influence of genetics on cannabis dependence in humans.

Researchers shrink laser-induced graphene for flexible electronics

You don't need a big laser to make laser-induced graphene (LIG). Scientists at Rice University, the University of Tennessee, Knoxville (UT Knoxville) and Oak Ridge National Laboratory (ORNL) are using a very small visible beam to burn the foamy form of carbon into microscopic patterns.

Fossilized insect from 100 million years ago is oldest record of primitive bee with pollen

Beetle parasites clinging to a primitive bee 100 million years ago may have caused the flight error that, while deadly for the insect, is a boon for science today.

New data shows rising repeat ER visits for opioid-related emergencies

The emergency department is being increasingly utilized as a patient's best or only treatment option for opioid use disorder (OUD). New analysis in Annals of Emergency Medicine shows that the prevalence of patients who visited emergency departments at four Indiana hospital systems for repeat opioid-related emergencies jumped from 8.8 percent of all opioid-related visits in 2012 to 34.1 percent in 2017—nearly a four-fold increase in just five years.

US health authority shipped faulty coronavirus test kits across country

A number of test kits sent out by US health authorities to labs across the country to diagnose the deadly novel coronavirus are faulty, a senior official said Wednesday.

Britain starts setting up 'first internet watchdog'

The British government said Wednesday it plans to allow its broadcast regulator to police the internet and issue substantial fines when social media giants fail to remove "online harm".

New material has highest electron mobility among known layered magnetic materials

All the elements are there to begin with, so to speak; it's just a matter of figuring out what they are capable of—alone or together. For Leslie Schoop's lab, one recent such investigation has uncovered a layered compound with a trio of properties not previously known to exist in one material.

World Mobile Congress cancelled over coronavirus fears

Organisers of the World Mobile Congress said Wednesday they have cancelled the world's top mobile trade fair due to fears stemming from the coronavirus that sparked an exodus of industry heavyweights.

EU seeks better coordination to tackle coronavirus

European Union nations will on Thursday discuss ways to increase cooperation in a bid to tackle the threat posed by the coronavirus which has killed over 1,100 people in China and spread to several EU member states.

UN: Congo's Ebola outbreak slows but still global emergency

The World Health Organization said although signs are now "extremely positive" in Congo that the Ebola outbreak is winding down, the epidemic remains a global health emergency.

Researchers develop 'multitasking' AI tool to extract cancer data in record time

As the second-leading cause of death in the United States, cancer is a public health crisis that afflicts nearly one in two people during their lifetime. Cancer is also an oppressively complex disease. Hundreds of cancer types affecting more than 70 organs have been recorded in the nation's cancer registries—databases of information about individual cancer cases that provide vital statistics to doctors, researchers, and policymakers.

Researchers link quartz microbalance measurements to international measurement system

Researchers at the National Institute of Standards and Technology (NIST) have found a way to link measurements made by a device integral to microchip fabrication and other industries directly to the recently redefined International System of Units (SI, the modern metric system). That traceability can greatly increase users' confidence in their measurements because the SI is now based entirely on fundamental constants of nature.

Protecting redundancy in the food web helps ensure ecological resilience

In 2014, a disease of epidemic proportions gripped the West Coast of the U.S. You may not have noticed, though, unless you were underwater.

Bacteriophages may play a role in childhood stunting... and be able to help treat it

New research spearheaded by McGill University has discovered that bacteriophages (viruses that infect bacteria) found in the intestinal tracts of children may play a role in childhood stunting, a significant impediment to growth that affects 22% of children under the age of five around the world.

How bird flocks with multiple species behave like K-pop groups

Birds of a feather don't always flock together: Peer into a forest canopy, and you will likely spot multiple bird species flying and feeding together, a phenomenon most spectacular in the Amazon where 50 species may travel as a unit. But are birds in these mixed flocks cooperating with one another or competing?

Cracks in perovskite films for solar cells easily healed, study finds

A new study reveals good news for the possibility of using perovskite materials in next-generation solar cells.

Faith-centered tattoos are analyzed in study of university students

With more than a quarter of U.S. adults now having tattoos—and nearly half of millennials sporting them—only a handful of studies have focused on religious tattoos. But a new study by researchers at Baylor University and Texas Tech University analyzes faith-centered tattoos and is the first to use visual images of them.

Researchers develop new method for analyzing metal

Warfighters on the battlefield often rely on machines, vehicles and other technologies with rotating parts to complete their mission. Army researchers have devised a new method of testing for a major factor in equipment failure and breakdown in order to ensure that those tools meet the proper standard of quality.

New etching technique could advance the way semiconductor devices are made

Microelectronics like semiconductor devices are at the heart of the technologies we use each day. As we move into an era where we are stretching the limits of Moore's Law, it is essential to find new ways to continue to pack more circuitry into each individual device in order to increase the speed and capability of our computers.

What is the best way to encourage innovation? Competitive pay may be the answer

Economists and business leaders agree that innovation is a major force behind economic growth, but many disagree on what is the best way to encourage workers to produce the "think-outside-of-the-box" ideas that create newer and better products and services. New research from the University of California San Diego indicates that competitive "winner-takes-all" pay structures are most effective in getting the creative juices flowing that help fuel economic growth.

Answers to microbiome mysteries in the gills of rainbow trout

While many immunologists use mouse models to conduct their research, J. Oriol Sunyer of Penn's School of Veterinary Medicine has made transformational scientific insights using a very different creature: rainbow trout.

Mind the trust gap: It's wider than you think

New Yorkers are more trusting of others compared to Alabamans or Texans. While this regional divide between southerners and the rest of Americans is well documented, the gap is wider than perceived, a study from York University reveals.
