Two immune system chemicals may trigger COVID-19 cytokine storms

Exactly how the coronavirus kills is a mystery. But part of the problem may be a partnership between just two immune system chemicals that triggers deadly organ damage. In mice, a combination of immune chemicals called TNF alpha and gamma interferon trips a domino chain of biochemical reactions that ultimately leads to three types of […]

Novel adoptive cell transfer method shortens timeline for T-cell manufacture — ScienceDaily

Adoptively transferred T-cells can prolong survival and sometimes cure patients with advanced solid tumors. While promising, it can take months to generate the necessary T-cells to help these patients. Such slow speed makes this therapy impractical for most patients who need immediate treatment. In the September issue of Cancer Research, Hannah Knochelmann, a student in […]

Rethinking Darwin’s Theory of Atoll Formation

Almost 200 years ago, during his voyage on the HMS Beagle, Charles Darwin charted reef systems around the world, many of them with astonishing accuracy. On the basis of his observations, he formed a theory for the formation of reef systems. A new paper challenges Darwin’s theory. In Darwin’s model, corals first form […]
