- newSimulations reveal how dominant SARS-CoV-2 strain binds to host, succumbs to antibodies
The dominant G-form spike protein 'puts its head up' more frequently to latch on to receptors, but that makes it more vulnerable to neutralization.

- COVID-19: Scientists identify human genes that fight infection
Scientists have identified a set of human genes that fight SARS-CoV-2 infection, the virus that causes COVID-19. Knowing which genes help control viral infection can greatly assist researchers' understanding of factors that affect disease severity and also suggest possible therapeutic options. The genes in question are related to interferons, the body's frontline virus fighters.

- Female protective effect: Researchers find clues to sex differences in autism
Researchers have found that autism may develop in different regions of the brain in girls than boys and that girls with autism have a larger number of genetic mutations than boys, suggesting that they require a larger 'genetic hit' to develop the disorder.

- New CRISPR technology offers unrivaled control of epigenetic inheritance
Scientists have figured out how to modify CRISPR's basic architecture to extend its reach beyond the genome and into what's known as the epigenome -- proteins and small molecules that latch onto DNA and control when and where genes are switched on or off.

- Experimental antiviral for COVID-19 effective in hamster study
The experimental antiviral drug MK-4482 significantly decreased levels of virus and disease damage in the lungs of hamsters treated for SARS-CoV-2 infection, according to a new study. MK-4482, delivered orally, is now in human clinical trials.

- Fit matters most when double masking to protect yourself from COVID-19
A new study shows that wearing two face coverings can nearly double the effectiveness of filtering out SARS-CoV-2-sized particles, preventing them from reaching the wearer's nose and mouth and causing COVID-19.

- Coronavirus does not infect the brain but still inflicts damage, study finds
SARS-CoV-2, the virus that causes COVID-19, does not infect brain cells but can inflict significant neurological damage, according to a new study of dozens of deceased patients.

- Highly dense urban areas are not more vulnerable to COVID-19, researchers say
A person who owns a car or who has a college education may be less vulnerable to COVID-19, according to an analysis of cases in Tehran, Iran, one of the early epicenters of the pandemic. While such variables do not inherently lower a person's risk, they do indicate an infrastructure of protection that persists despite how densely populated a person's district might be.

- Research shows to disrupt online extremism freewill is key
According to new research, when people are explicitly told that they are free to accept or reject propagandistic claims, the likelihood of choosing a moderate view increases. This was a result of a survey of attitudes that tested counter-propaganda strategies, which stressed a person's autonomy, and then measured sentiments after exposure.
