Scientists generate a detailed molecular atlas of lung development

Researchers at the Perelman School of Medicine at the University of Pennsylvania have produced a detailed molecular atlas of lung development, which is expected to be a fundamental reference in future studies of mammalian biology and of new treatments for diseases, such as COVID-19, that affect the lungs.

Study shows SARS-CoV-2 antibodies wane at different rates

Researchers from Duke-NUS Medical School, the National Centre for Infectious Diseases (NCID), and the Agency for Science, Technology and Research (A*STAR) Infectious Diseases Labs have discovered that antibodies against SARS-CoV-2 decline at different speeds, and these antibodies last for only a few days in some people but remain for many years in other individuals.

Hormone drugs may help disarm coronavirus spike protein and stop disease progression

Hormone drugs that reduce androgen levels may help disarm the coronavirus spike protein used to infect cells and stop the progression of severe COVID-19 disease, suggests a new preclinical study from researchers in the Abramson Cancer Center at the University of Pennsylvania and published online in Cell Press's iScience.

Study provides clues for designing more effective antiviral drugs

An international research team from the University of Turku based in Finland and PennState University based in the United States has solved an ancient puzzle of how living organisms differentiate between DNA and RNA building blocks at the time of gene expression, offering new possibilities for designing novel antiviral medications.

Mutant peptides derived from SARS-CoV-2 hamper activation of CD8+ killer T cells

A deep sequencing study of 747 SARS-CoV-2 virus isolates has revealed mutant peptides derived from the virus that cannot effectively bind to critical proteins on the surface of infected cells and, in turn, hamper activation of CD8+ killer T cells that recognize and destroy these infected cells.

UN research: 17% of total food available to consumers went into waste bins

An estimated 931 million tonnes of food, or 17% of total food available to consumers in 2019, went into the waste bins of households, retailers, restaurants and other food services, according to new UN research conducted to support global efforts to halve food waste by 2030.

Three new COVID-19 variants can evade antibodies that act against original virus

New research at Washington University School of Medicine in St. Louis indicates that three new, fast-spreading variants of the virus that cause COVID-19 can evade antibodies that work against the original form of the virus that sparked the pandemic.

SARS-CoV-2 can make itself unrecognizable to immune response by T-killer cells through mutations

The body's immune response plays a crucial role in the course of a SARS-CoV-2 infection. In addition to antibodies, the so-called T-killer cells, are also responsible for detecting viruses in the body and eliminating them.

Legal wildlife trade needs monitoring to reduce emerging zoonotic diseases

With three out of four newly emerging infectious human diseases originating in animals, there is an urgent need to monitor the legal trade in wildlife, according to new research by Vincent Nijman, Professor in Anthropology at Oxford Brookes University.

Genomics study examines the impact of COVID-19 on care homes

Care homes are at high risk of experiencing outbreaks of COVID-19, the disease caused by SARS-CoV-2. Older people and those affected by heart disease, respiratory disease and type 2 diabetes - all of which increase with age - are at greatest risk of severe disease and even death, making the care home population especially vulnerable.
