Treating coronavirus patients with alpha-blockers may help prevent the cytokine storm associated with severe COVID-19 infection. Alpha-blockers interfere with the cell signaling that triggers cytokine storms. Mice with bacterial infections that were treated with alpha-blockers experienced reduced cytokine storms and decreased death rates.

In the intestines, signals of sugar ingestion travel to the brain, sparking an appetite for more sweet foods. However, this pathway only responds to sugars, not artificial sweeteners.
Researchers have identified a set of genes that may have influenced human brain size, which helped us diverge from other apes. The study reveals the genes are unique to humans and help to build the neocortex.
