A glycan controls how SARS-CoV-2’s spike protein opens, study finds

Using simulations, a team of researchers in the U.S. found that the glycan at position N343 of the SARS-CoV-2 spike protein’s receptor-binding domain (RBD) helps in its opening. A mechanism that aids its binding to the host cell receptor.

Researchers evaluate frequency of SARS-CoV-2 in hematology/oncology settings

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.

SARS-CoV-2 D614G mutation associated with lower antibody binding

The onset of the COVID-19 pandemic has brought about an international effort to uncover the biology of its causative agent, SARS-CoV-2, and to develop effective and safe antivirals to contain and treat the infection. A new study by a team of researchers in France and Sweden discusses one such study, exploring the relative immunogenicity of the three main structural proteins of the virus.

One in five people lack protein α-actinin-3 in their muscle fiber, shows study

Almost one in five people lack the protein α-actinin-3 in their muscle fibers. Researchers at Karolinska Institutet in Sweden now show that more of the skeletal muscle of these individuals comprises slow-twitch muscle fibers, which are more durable and energy-efficient and provide better tolerance to low temperatures than fast-twitch muscle fibers.
