TORONTO, ON - American adults 65 years old and older have better vision than that age group did nearly a decade ago, according to a recent study published in the journal Ophthalmic Epidemiology.
In 2008, 8.3% of those aged 65 and older in the US reported serious vision impairment. In 2017 that number decreased to 6.6% for the 65-plus cohort. Put another way: if vision impairment rates had remained at 2008 levels, an additional 848,000 older Americans would have suffered serious vision impairment in 2017.
NEW YORK (March 17, 2021) -- High speed air dryers not only leave more contamination on poorly washed hands compared to paper towels, but during hand drying, they can also spread germs onto clothing, ultimately transferring more bacteria to other surfaces, according to a study published today in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America.

March 17, 2021-- A new study published online in the Annals of the American Thoracic Society reveals how socioeconomic factors partially explain the increased odds that Black and Hispanic Americans have of testing positive for SARS-CoV-2, the virus that causes COVID-19.
Researchers at University of Illinois Urbana-Champaign developed software to improve the accuracy of 3D-printed parts, seeking to reduce costs and waste for companies using additive manufacturing to mass produce parts in factories.

OSAKA, Japan. Quantum computers have seen a lot attention recently as they are expected to solve certain problems that are outside the capabilities of normal computers. Primary to these problems is determining the electronic states of atoms and molecules so they can be used more effectively in a variety of industries - from lithium-ion battery designs to in silico technologies in drug development.
This is a landmark study in so far as being the first to raise the alarm that, despite early successes with Covid-19 vaccines, further research is warranted on a next generation of Covid-19 vaccines.
The results from this study, however, only indicate that the AstraZeneca vaccine does not have at least 60% efficacy against mild-moderate Covid-19 due to the B.1.351 (N501Y.V2) variant.
According to a new study published in the Journal of the Royal Society of Medicine, the carbon footprint of personal protective equipment (PPE) provided to health and social care staff in England during the first six months of the COVID-19 pandemic was equivalent to flying from London to New York 244 times every day. The good news is that adopting a range of strategies including increased UK manufacture, reusing and recycling could reduce the environmental impact of PPE dramatically while maintaining the safety of staff and patients.
Researchers at Lund University in Sweden have designed a new bioink which allows small human-sized airways to be 3D-bioprinted with the help of patient cells for the first time. The 3D-printed constructs are biocompatible and support new blood vessel growth into the transplanted material. This is an important first step towards 3D-printing organs. The new study has been published in Advanced Materials.
The use of artificial light at night around the world has increased enormously in recent years, causing adverse effects on the survival and reproduction of nocturnal organisms. Artificial light at night interferes with vital ecological processes such as the nighttime pollination of plants by nocturnal insects, which could have consequences for agricultural crop yields and reproduction of wild plants.
Not least because of the COVID-19 pandemic, conspiracy theories are more topical than ever. They are reported and discussed in almost all media and communication channels. But what influence do they have on our behavior? Scientists led by behavioral economist Loukas Balafoutas investigated this question in a recently published study. The result: We don't need to believe in conspiracy theories for them to have an impact on us. Merely being confronted with them suffices.
One of the most vital functions performed by the cells in our body is DNA repair, a task so crucial to our well-being that failing to execute it can lead to consequences as dreadful as cancer. The process of DNA repair involves a complex interplay between several gene pathways and proteins. One such pathway is the "Fanconi anemia (FA) pathway," whose genes participate in DNA repair. FANCM, a component of this pathway, is tasked with the elimination of harmful DNA "inter-strand cross-links," and interacts with another component called MHF in order to function.
Hepatitis B virus (HBV) infections are among the major global health problems. Particularly problematic is the high number of chronic courses of the disease, causing the deaths of more than 800.000 people globally every year. So far, there is no therapy to cure the condition. "With the discovery of a new hepatitis B virus in donkeys and zebras capable of causing prolonged infections, we now have the opportunity for a better understanding of the chronic course of the disease and thus also for mitigation or prevention of severe clinical consequences," explains Prof. Dr.
A new study uncovers which cell types can be infected by SARS-CoV-2 due to their viral entry factors. The study also suggests that increased gene expression of these viral entry factors in some individuals partially explains the differences of COVID-19 severity reported in relation to age, gender and smoking status. The study evolved from the Human Cell Atlas Lung Biological Network with main contributions from Helmholtz Zentrum München, the Broad Institute of MIT and Harvard, the Wellcome Sanger Institute and University Medical Center Groningen.
