Researchers at Tokyo Institute of Technology working in collaboration with colleagues at the Kanagawa Institute of Industrial Science and Technology and Nara Medical University in Japan have succeeded in preparing a material called cerium molybdate (γ-Ce2Mo3O13 or CMO), which exhibits high antiviral activity against coronavirus.
Results of a 2018 multirocket launch at Poker Flat Research Range north of Fairbanks, Alaska, will help scientists better understand the impact of more water vapor accumulating near the fringe of the Earth's atmosphere.
"This is the first time anyone has experimentally demonstrated that cloud formation in the mesosphere is directly linked to cooling by water vapor itself," said Irfan Azeem, space physicist at Astra LLC in Louisville, Colorado, and principal investigator of the Super Soaker mission.
Major changes in bereavement care have occurred during the COVID-19 pandemic, amid a flood of demand for help from bereaved people, according to new research from the University of Cambridge. The first major study of pandemic-related changes in bereavement care has found that the switch to remote working has helped some services to reach out, but many practitioners feel they do not have capacity to meet people's needs.
Materials called perovskites can be more readily incorporated into silicon-based semiconducting platforms by using a microfluidic pumping technology developed at KAUST.
The perovskites currently being explored for many applications in new technologies are diverse materials sharing the same crystalline structure as the natural mineral perovskite. These semiconducting materials show great promise in a variety of optoelectronic applications, such as light emitters, sensors and solar cells.
COLUMBUS, Ohio - Parents may fear that if their high school student isn't motivated to do well in classes, there's nothing that will change that.
But a new study that followed more than 1,600 students over two years found that students' academic motivation often did change - and usually for the better.
Results showed that increasing students' sense of "belongingness" in school was one key way of increasing academic motivation.
Electric scooters or "e-scooters" are taking over cities worldwide and have broad appeal with tourists. Although e-scooter use declined during the COVID-19 pandemic, its popularity could rebound rapidly, especially if travelers start to substitute scooters for transit on some shorter trips. Shared e-scooters in particular, are a rapidly emerging mode of transportation, but present a host of regulatory challenges from equitable distribution to parking infrastructure to pedestrian safety, among others.
An associate professor from RUDN University found out the effect of the number and size of pores on the permeability of bone implants by biological fluids. The results of the study could help choose the optimal physical parameters of implants. The results of the study were published in the International Journal of Engineering.
Wildlife tourism including white shark cage-diving is growing in popularity, but these industries remain highly contentious amongst tourists, conservationists, and scientists alike.
Many voice concerns about possible negative impacts - especially when it targets potentially dangerous animals - while proponents cite the socio-economic benefits to justify wildlife tourism activities.
In reality, wildlife tourism is complex, requiring managers to balance the benefits and drawbacks to determine what is acceptable for such industries.
Physicists from Russia, Chile, Brazil, Spain, and the UK, have studied how the magnetic properties change in 3D nanowires, promising materials for various magnetic applications, depending on the shape of their cross-section. Particularly, they more deeply probed into the Walker breakdown phenomenon, on the understanding of which the success of the implementation of the future electronics devices depends. The research outcome appears in Scientific Reports.
Hypertrophic cardiomyopathy (HCM) is a cardiovascular disease characterized by thickening of the left ventricle, otherwise known as the main squeezing chamber of the heart. HCM is best known for causing sudden death in athletes but can occur in persons of any age, often without symptoms. While frequently discussed in the context of genetics, most patients with HCM do not have a known genetic variant. Investigators from Brigham and Women's Hospital uncovered a means to study the complexity of this disease beyond the identification of individual genes.
While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights into the particles that build our universe.
Now, researchers hunting for these squeezed protons at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility have come up empty handed, suggesting there's more to the phenomenon than first thought. The result was recently published in Physical Review Letters.
States regularly use administrative records, such as motor-vehicle data, in determining whether people have moved to prune their voter rolls. A Yale-led study of this process in Wisconsin shows that a significant percentage of registered voters are incorrectly identified as having changed addresses, potentially endangering their right to vote.
Litter is not only a problem on Earth. According to NASA, there are currently millions of pieces of space junk in the range of altitudes from 200 to 2,000 kilometers above the Earth's surface, which is known as low Earth orbit (LEO). Most of the junk is comprised of objects created by humans, like pieces of old spacecraft or defunct satellites.
ITHACA, N.Y. - A team from Cornell University's Environmental Systems Lab, led by recent graduate Allison Bernett, has put forth a new framework for injecting as much information as possible into the pre-design and early design phases of a project, potentially saving architects and design teams time and money down the road.
WEST LAFAYETTE, Ind. -- Doppler radar improves lives by peeking inside air masses to predict the weather. A Purdue University team is using similar technology to look inside living cells, introducing a method to detect pathogens and treat infections in ways that scientists never have before.
