WASHINGTON, August 11, 2020 -- Since the COVID-19 virus spreads through respiratory droplets, researchers in India set out to explore how droplets deposited on face masks or frequently touched surfaces, like door handles or smartphone touch screens, dry.
Droplets can be expelled via the mouth or nose while coughing, sneezing or simply talking. These droplets are tiny, around twice the width of a human hair, and studies have shown a substantially reduced chance of infection once they dry.
COLUMBUS, Ohio - Bifocal contact lenses aren't just for aging eyes anymore. In nearsighted kids as young as 7 years old, multifocal contact lenses with a heavy dose of added reading power can dramatically slow further progression of myopia, new research has found.
In the three-year clinical trial of almost 300 children, a bifocal contact lens prescription with the highest near-work correction slowed nearsightedness progression by 43 percent when compared to single-vision contact lenses.
Imagine plugging in to your brick house.
Red bricks -- some of the world's cheapest and most familiar building materials -- can be converted into energy storage units that can be charged to hold electricity, like a battery, according to new research from Washington University in St. Louis.
Doctors are overworked and in short supply across the globe, but they could soon be assisted by machine learning to help reduce errors in primary care. AI symptom checkers are tremendously valuable in providing medical information and safe triaging advice to users, however, none of them performs diagnosis like a doctor. Unlike doctors, existing symptom checkers provide advice based on correlations alone - and correlation is not causation. Researchers at Babylon have, for the first time that we know of, used the principles of causal reasoning to enable AI to diagnose written test cases.

Synchronization, in which a complex system operates as one body, is an important phenomenon that takes place in an enormous range of scales -- from subatomic particles to galaxies. In biology, fish, birds, and even cells synchronize in order to survive. Group synchronization is essential to human beings, and critical to our physical and mental health. Examples of synchronization can be seen in drivers on the road or in a crowd of people clapping hands together. Today, in order for a group of people to make a decision, they don't have to meet.
Materials scientists studying recharging fundamentals made an astonishing discovery that could open the door to better batteries, faster catalysts and other materials science leaps.
Philadelphia, August 11, 2020 - A team of researchers at Children's Hospital of Philadelphia (CHOP) affiliated with the CHOP Epilepsy Neurogenetics Initiative (ENGIN) further bridged the gap between genomic information and clinical outcome data by systematically linking genetic information with electronic medical records, focusing on how genetic neurological disorders in children develop over time. The findings were published today in the journal Genetics in Medicine.
Ana Losada, from the Spanish National Cancer Research Centre (CNIO), is the scientist who identified cohesin in vertebrates, a protein that is essential in cell division. Losada has studied cohesin since she identified it in vertebrates in 1998, at the Cold Spring Harbor Laboratory in New York. "It is fascinating," she says. "Now we know that cohesin plays a role in several types of cancer, and a large number of researchers worldwide have become greatly interested in this protein complex."
CAMBRIDGE, MA -- At the height of a thunderstorm, the tips of cell towers, telephone poles, and other tall, electrically conductive structures can spontaneously emit a flash of blue light. This electric glow, known as a corona discharge, is produced when the air surrounding a conductive object is briefly ionized by an electrically charged environment.
For centuries, sailors observed corona discharges at the tips of ship masts during storms at sea. They coined the phenomenon St. Elmo's fire, after the patron saint of sailors.
Scientists have been warning about an "insect apocalypse" in recent years, noting sharp declines in specific areas -- particularly in Europe. A new study shows these warnings may have been exaggerated and are not representative of what's happening to insects on a larger scale.
University of Cincinnati physicists, as part of an international research team, are raising doubts about the existence of an exotic subatomic particle that failed to show up in twin experiments.
UC College of Arts and Sciences associate professor Alexandre Sousa and assistant professor Adam Aurisano took part in an experiment at the Fermi National Accelerator Laboratory in search of sterile neutrinos, a suspected fourth "flavor" of neutrino that would join the ranks of muon, tau and electron neutrinos as elementary particles that make up the known universe.
SCOTTSDALE, Ariz. -- Aug 11, 2020 -- Working with an international team of researchers, HonorHealth Research Institute and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, were instrumental in one of the first clinical trials showing how pancreatic cancer patients can benefit from immunotherapy, according to a four-year study published in a premier scientific journal, Nature Medicine.
NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of former Typhoon Mekkhala shortly after it made landfall in southeastern China. Wind shear had torn the storm apart.
Mekkhala made landfall in Fujian, southeastern China, bringing strong winds and torrential rain. According to the China Meteorological Agency, the typhoon came ashore in coastal areas of Zhangpu County at around 7:30 a.m. local time on Aug. 11 (7:30 p.m. EDT on Aug. 10). The storm generated at least 170 mm (6.7 inches) of rainfall in Zhangpu County by the middle of the day on Aug. 11.
Reston, VA--Researchers have developed a simplified process that could enhance personalization of cancer therapy based on a single nuclear medicine scan. The novel method uses a follow-up single photon emission computed tomography/computed tomography (SPECT/CT) scan to obtain reliable radiation dose estimates to tumors and at-risk organs. The study is published in The Journal of Nuclear Medicine.
