WASHINGTON, April 27, 2021 -- If a base station in a local area network tries to use a directional beam to transmit a signal to a user trying to connect to the network -- instead of using a wide area network broadcast, as base stations commonly do -- how does it know which direction to send the beam?
Abu Dhabi, UAE, April 27, 2021: As people around the world increasingly get their news from social media, online misinformation has emerged as an area of great concern.
Aerosol products used in the home now emit more harmful volatile organic compound (VOC) air pollution than all the vehicles in the UK, new research shows.
A new study by the University of York and the National Centre for Atmospheric Science reveals that the picture is damaging globally with the world's population now using huge numbers of disposable aerosols - more than 25 billion cans per year.
This is estimated to lead to the release of more than 1.3 million tonnes of VOC air pollution each year, and could rise to 2.2 million tonnes by 2050.
Arum Han, professor in the Department of Electrical and Computer Engineering at Texas A&M University, and his collaborators have designed an experimental system that shows exposure of coronavirus to a very high temperature, even if applied for less than a second, can be sufficient to neutralize the virus so that it can no longer infect another human host.
The Marcellus Formation straddles the New York State and Pennsylvania border, a region that shares similar geography and population demographics. However, on one side of the state line unconventional natural gas development - or fracking - is banned, while on the other side it represents a multi-billion dollar industry. New research takes advantage of this 'natural experiment' to examine the health impacts of fracking and found that people who live in areas with a high concentration of wells are at higher risk for heart attacks.
A team of engineering researchers at the Georgia Institute of Technology hopes to uncover new ways to diagnose and treat brain ailments, from tumors and stroke to Parkinson's disease, leveraging vibrations and ultrasound waves.
DALLAS (SMU) - An international team of paleontologists has identified a new genus and species of hadrosaur or duck-billed dinosaur, Yamatosaurus izanagii, on one of Japan's southern islands.
The fossilized discovery yields new information about hadrosaur migration, suggesting that the herbivors migrated from Asia to North America instead of vice versa. The discovery also illustrates an evolutionary step as the giant creatures evolved from walking upright to walking on all fours. Most of all, the discovery provides new information and asks new questions about dinosaurs in Japan.
Researchers at the Pritzker School of Molecular Engineering (PME) at the University of Chicago have designed a completely novel potential treatment for COVID-19: nanoparticles that capture SARS-CoV-2 viruses within the body and then use the body's own immune system to destroy it.
These "Nanotraps" attract the virus by mimicking the target cells the virus infects. When the virus binds to the Nanotraps, the traps then sequester the virus from other cells and target it for destruction by the immune system.
New studies from the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) shed more light on the economic and environmental costs of mandates in the Renewable Fuels Standard (RFS), a federal program to expand the nation's biofuels sector.
Researchers said the studies indicate the need to adopt more targeted policies that value the environmental and ecosystem benefits of perennial bioenergy crops over cheaper options -- and provide financial incentives for farmers to grow them.
MEMPHIS, Tenn. - For the first time in published literature, Le Bonheur Children's Hospital and University of Tennessee Health Science Center (UTHSC) researchers showed that a variety of white blood cells known as eosinophils modify the respiratory barrier during influenza A (IAV) infection, according to a recent paper in the journal Cells. This research could have implications in understanding SARS-CoV-2 (COVID-19) infection in asthmatic patients.
An Academic Analytics Research Center (AARC) study published in the journal Scientometrics found that senior faculty (scholars who earned their terminal degree 30 or more years ago) research publication activity exceeded expectations based on age cohort population for book chapters and book publications, and senior scholars largely kept pace in terms of journal article publications.
Irvine, Calif., April 27, 2021 -- University of California, Irvine biologists have developed a new genetically engineered mouse model that, unlike its predecessors, is based on the most common form of Alzheimer's disease. The advance holds promise for making new strides against the neurodegenerative disease as cases continue to soar. Their study appears in the journal, Nature Communications.

Just as humans receive the first members of their microbiomes from their mothers, seeds may harbor some of the first microorganisms plants encounter. While these initial microbes could become influential players in the plants' microbiomes, the microbial communities that colonize seeds have not received as much attention as root, shoot, or soil microbiomes.
Researchers have spent more than three decades developing and studying miniature biosensors that can identify single molecules. In five to 10 years, when such devices may become a staple in doctors' offices, they could detect molecular markers for cancer and other diseases and assess the effectiveness of drug treatment to fight those illnesses.
Skoltech researchers used Google Trends' Big Data ensuing from human interactions with the Internet to develop a new methodology - a tool and a data source - for analyzing and researching the growth of startups. A paper reporting these important findings was published in technology management journal, Technological Forecasting and Social Change.
