Researchers identify a neural pathway critical to correcting behavioral errors

Mount Sinai researchers have identified a neural pathway through which the brain detects errors and guides subsequent behavioral improvement. This process, called cognitive control, is frequently dysregulated in a wide range of psychiatric disorders.

Researchers develop a mathematical means of assessing COVID-19 tests' false-negative rate

Even with more than 1.5 million Americans receiving a COVID vaccine each day, officials estimate it will take many more months before enough people are protected from the deadly virus.

Scientists find new therapeutic approach to effectively treat age-related macular degeneration

Runt-related transcription factor 1 (RUNX1) has been linked to retinal neovascularization and the development of abnormal blood vessels, which result in vision loss in diabetic retinopathy.

Organ transplant patient dies after receiving Covid-infected lungs

Doctors say a woman in Michigan contracted covid-19 and died last fall two months after receiving a tainted double-lung transplant from a donor who turned out to harbor the virus that causes the disease — despite showing no signs of illness and initially testing negative.

Salt reduction program will lead to health benefits, cost savings by 2050

England's salt reduction programme will have led to nearly 200,000 fewer adults developing heart disease and £1.64 billion of healthcare cost savings by 2050, according to research by Queen Mary University of London.

Study could lead to new strategies to prevent various cancers

Chronic inflammation drives the development of various cancers, including those of the skin, colon and pancreas. Investigators at Massachusetts General Hospital (MGH) who previously demonstrated high expression levels of an immune molecule called interleukin-33 (IL-33) during cancer-promoting inflammation have now uncovered the details behind the molecule's effects.

Could an intranasal adjuvant to vaccines boost immunity against SARS-CoV-2 variants?

A research team from the University of Michigan Medical School, USA, developed a supplementary intranasal treatment to improve COVID-19 vaccine response and its effects on long-lasting immunity from other variants, such as the B.1.351 variant first found in South Africa.

High fructose diets might prevent proper functioning of peoples' immune system

New research by Swansea scientists in collaboration with researchers at the University of Bristol and the Francis Crick Institute in London has indicated that consuming a diet high in sugar fructose might prevent the proper functioning of peoples' immune systems in ways that have, until now, largely been unknown.

Experts advocate for increased diversity in vaccine clinical trials

A team of scientific experts from across the U.S. and Puerto Rico are advocating for increased diversity in vaccine trials after publishing a new report that highlights a decade's worth of disparities.

Scientists use computer simulations to identify future targets for treatment of Covid-19

University of Warwick scientists model movements of nearly 300 protein structures in Covid-19. Scientists can use the simulations to identify potential targets to test with existing drugs, and even check effectiveness with future Covid variants.

Levels of IgG antibodies may influence COVID-19 outcomes

COVID-19, the source of the current pandemic, may be caused by a single virus, but it has a variety of presentations that make treatment difficult. Children, for example, almost exclusively experience mild or asymptomatic COVID-19, while adults can develop severe or even fatal COVID-19.

Polycomb complexes found to be essential for proper skin development

Mount Sinai researchers have discovered that Polycomb complexes, groups of proteins that maintain gene expression patterns, are essential for proper skin development, according to a paper published in Genes & Development on February 18.

Study reveals extremely low detection of SARS-CoV-2 on surfaces in oncology facilities

Researchers from Rutgers Cancer Institute of New Jersey, the state's only National Cancer Institute-designated Comprehensive Cancer Center, evaluated the frequency of SARS-CoV-2, the virus that causes COVID-19, on various environmental surfaces in outpatient and inpatient hematology/oncology settings located within Rutgers Cancer Institute and Robert Wood Johnson University Hospital, an RWJBarnabas Health facility.
