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.
Sweet tasting foods don't only trigger the taste buds, they also switch on a neurological pathway that begins in the gut.

Glial cells and radial astrocytes might control the decision to give up swimming against the current in Zebrafish.
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.
Researchers have created a revolutionary new tool to help shed light on living cells. By combining two existing imaging technologies, researchers were able to image living cells in 3D.
