Monoclonal antibody prevents HIV infection in monkeys, study finds

Eurekalert - Jun 07 2021 - 00:06
The experimental, lab-made antibody leronlimab can completely prevent nonhuman primates from being infected with the monkey form of HIV, new research published in Nature Communications shows. The results will inform a future human clinical trial evaluating leronlimab as a potential pre-exposure prophylaxis, or PrEP, therapy to prevent human infection from the virus that causes AIDS.

In Oregon, new gun violence restraining orders appear to be used as intended, but could be used more proactively

Eurekalert - Jun 07 2021 - 00:06
A new study examined ERPO use in Oregon in the first 15 months after it was adopted. The study found that while extreme risk protection orders (ERPOs) are commonly considered as a tool to remove guns from dangerous individuals, they should also be considered as a tool to prevent gun purchases by dangerous individuals.

Researchers discover how cowpea mosaic plant virus activates immune system against cancer

Eurekalert - Jun 07 2021 - 00:06
Cowpea mosaic virus, when injected into cancerous tumors, stimulates the immune system to attack and often eliminate the tumor. In a new study, immunology researchers in Dartmouth's and Dartmouth-Hitchcock's Norris Cotton Cancer Center, in collaboration with researchers at the University of California San Diego Jacobs School of Engineering, characterize the previously unidentified pathways through which CPMV is recognized by the immune system, opening the door for pursuit of CPMV as a new biological cancer treatment.

Papers explore massive plankton blooms with very different ecosystem impacts

Eurekalert - Jun 07 2021 - 00:06
Two new papers explore this question and provide examples of conditions that lead to massive plankton blooms with vastly different potential impacts on the ecosystem, according to McGillicuddy, co-author of both papers. Both papers also point to the importance of using advanced technology--including Video Plankton Recorders, autonomous underwater vehicles, and the Ocean Observatories Initiative's Coastal Pioneer Array--to find and monitor these blooms.
