Vision impairment is associated with mortality

Scientists at Walter Reed Army Institute of Research, in a collaboration the Duke University, have confirmed that monoclonal antibodies can be an effective tool in the global fight against malaria. The study, led by Dr. Sheetij Dutta, chief of the Structural Vaccinology Laboratory at WRAIR, showed that mAbs such as CIS43 were most effective in a culture-based assay that measured a malaria parasite's ability to infect a human liver cell, while another mAb 317 showed the best activity in a mouse infection model. Dutta added, "difference in assay outcomes for mAbs could reflect distinct sites on the circumsporozoite protein, that can be exploited for developing improved vaccines." The study results were published today in in Nature Scientific Reports. Despite decades ...

If you are going to buy a face mask to protect yourself and others from COVID-19, make sure it's a three-layered mask. You might have already heard this recommendation, but researchers have now found an additional reason why three-layered masks are safer than single or double-layered alternatives. While this advice was originally based on studies that showed three layers prevented small particles from passing through the mask pores, researchers have now shown that three-layered surgical masks are also most effective at stopping large droplets from a cough or sneeze from getting atomized into smaller droplets. These large cough droplets can penetrate through the single- and double-layer masks and atomize to much smaller droplets, ...

Mount Sinai Researchers find a new way to prevent attention deficits associated with Fragile X, a leading genetic cause of autism, in an animal model Corresponding Author: Hirofumi Morishita, MD, PhD, Department of Psychiatry, Neuroscience, Friedman Brain Institute, Mindich Child Health and Development Institute, Icahn School of Medicine at Mount Sinai, New York. Bottom Line: The adolescent maturation of the frontal cortex is important for establishing cognitive function, and disruption of this process is associated with neurodevelopmental disorders. This study uncovered a new molecular driver of frontal circuit maturation that is essential ...

ORLANDO, March 5, 2021 - Nuisance flooding has increased on U.S. coasts in recent decades due to sea level rise, and new research co-authored by the University of Central Florida uncovered an additional reason for its added frequency. In a study appearing today in the journal Science Advances, researchers show that higher local tide ranges, most likely from human alterations to coastal areas and estuaries, has increased the number of nuisance flooding days in many coastal locations in the U.S. Coastal nuisance flooding is considered to be minor flooding from the seas that causes problems such as flooded roads and ...

Could cactus pear become a major crop like soybeans and corn in the near future, and help provide a biofuel source, as well as a sustainable food and forage crop? According to a recently published study, researchers from the University of Nevada, Reno believe the plant, with its high heat tolerance and low water use, may be able to provide fuel and food in places that previously haven't been able to grow much in the way of sustainable crops. Global climate change models predict that long-term drought events will increase in duration and intensity, resulting in both higher temperatures and lower levels of available water. Many crops, such as rice, corn and soybeans, have an upper temperature limit, and ...

In early 2016, an icy visitor from the edge of our solar system hurtled past Earth. It briefly became visible to stargazers as Comet Catalina before it slingshotted past the Sun to disappear forevermore out of the solar system. Among the many observatories that captured a view of this comet, which appeared near the Big Dipper, was the Stratospheric Observatory for Infrared Astronomy (SOFIA), NASA's telescope on an airplane. Using one of its unique infrared instruments, SOFIA was able to pick out a familiar fingerprint within the dusty glow of the comet's tail--carbon. Now this one-time visitor to our inner solar system is helping explain ...

When stay-at-home orders were announced as one of the greatest tools in our arsenal against the COVID-19 pandemic, anyone who's vintage enough to have watched forward-looking shows and movies-- from "The Jetsons" to "Star Trek" to "Back to the Future" -- might have thought America was ready to embrace a world where video calling and other tech-heavy communication options reigned supreme. But one year, dozens of Zoom meetings, hundreds of phone calls and text messages, thousands of online gaming hours, and millions of social media posts later, new research led by UNLV has ...

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) found large quantities of previously undetectable compounds from the family of chemicals known as PFAS in six watersheds on Cape Cod using a new method to quantify and identify PFAS compounds. Exposures to some PFAS, widely used for their ability to repel heat, water, and oil, are linked to a range of health risks including cancer, immune suppression, diabetes, and low infant birth weight. The new testing method revealed large quantities of previously undetected PFAS from fire-retardant foams and other unknown sources. Total concentrations of PFAS present in these watersheds were above state maximum contaminant ...

Researchers from Japan and Indonesia have pioneered a new method for more accurately estimating the source of weak ground vibrations in areas where one tectonic plate is sliding under another in the sea. Applying the approach to Japan's Nankai Trough, the researchers were able to estimate previously unknown properties in the region, demonstrating the method's promise to help probe properties needed for better monitoring and understanding larger earthquakes along this and other plate interfaces. Episodes of small, often imperceptible seismic events ...

African American breast cancer survivors are four times more likely to die from breast cancer than women of all other races and ethnicities, and they have a disproportionately high rate of death from cardiovascular disease (CVD). New research led by George Mason University's College of Health and Human Services faculty Dr. Michelle Williams assessed African American breast cancer survivors' risk factors and knowledge about CVD in the Deep South, where health disparities between African American women and women of other races is even larger. They found that although African American breast cancer survivors have a higher prevalence of CVD risk factors, their knowledge about CVD is low. The study was published in the Journal of Health Disparities Research and Practice in February. ...
