Study shows how cancer cells gain access to nerve signal to enter the bloodstream

Tumors come in many shapes and forms--curable or deadly, solid or liquid, lodged inside the brain, bone, or other tissues. One thing they all have in common, however, is a knack for molecular deceit.

Novel training reduces anger, aggression and hostile attribution bias in social conflict situations

Scientists at the Walter Reed Army Institute for Research and Army Research Laboratory have developed a computer-based training to reduce anger, reactive aggression and hostile attribution bias--the tendency to attribute hostile intent to the actions of others--in ambiguous social conflict situations.

Different triggers for Kawasaki disease suggest slightly different genetic susceptibilities

Researchers at University of California San Diego report that while Kawasaki disease (KD) occurs in clusters, the traits, and thus the triggers of the inflammatory disease vary among clusters. The findings are published in the September 2020 online issue of The Journal of Pediatrics.

Australian scientists develop a nasal spray that could stop SARS-CoV-2 infection

The novel product, called INNA-051, is being developed by Ena Respiratory, and laboratory experiments have shown that it reduced viral replication by as much as 96 percent in the animal study. Spearheaded by Public Health England’s (PHE) Deputy Director, Professor Miles Carroll, the new study described the potential treatment and has been published in the open-source preprint server bioRxiv*.

Self-collection of blood for COVID-19 antibody testing may be a reliable and easy alternative

Some evidence suggests that IgGs appear at 6-15 days after infection and may persist for months. However, large-scale testing over time is required to understand the immunological response to COVID-19 with greater accuracy. A recent pilot study published on the preprint server medRxiv in September 2020 reports the use of self-collected capillary blood for serology, with highly promising results.
