For infection-fighting cells, a guideline for expanding the troops

A team from Princeton University used mathematical modeling to explore the relationship between T cell expansion and infectious agent levels. They found that the starting amount of infectious agent and affinity for the cells are key factors in determining the expansion rate. The study suggests a simple underlying mechanism governing th...

Brain stimulation improves depression symptoms, restores brain waves in clinical study

A clinical study led by Flavio Frohlich at UNC School of Medicine successfully reduced depression symptoms in about 70 percent of participants using transcranial alternating current stimulation (tACS). The treatment target specific alpha oscillations in the brain, bringing them back into balance and decreasing symptoms.

Fusion science and astronomy collaboration enables investigation of the origin of heavy elements

A research team has successfully computed millions of highly accurate atomic data for neodymium ions, enabling studies of the origin of precious metals like gold and platinum. The findings show that the light of a kilonova, emitted by neutron star mergers, contains abundant heavy elements.

When green 'fixes' actually increase the carbon footprint

A study by University of Pennsylvania sociologists found that high-income residents moving into tech-enabled neighborhoods increase carbon emissions, displacing low-income populations. The research highlights the need for affordable housing and sustainable planning to counteract gentrification's negative effects.

AJTMH tipsheet for March 2019

Researchers analyzed sentinel chickens to detect Eastern equine encephalitis virus, finding its presence year-round in the Florida Panhandle. A new hand-washing product, SuperTowel, shows potential to limit disease spread in humanitarian crises. The global 'pandemic' of fake medicines kills over 250,000 children annually.

An international study co-led by CNIO identifies a 'sensor' that activates cell migration

A recent study has found that Focal Adhesion Kinase (FAK) acts as a sensor to mechanical forces generated by the cytoskeleton, activating biochemical signals regulating cell migration. This discovery provides new insights into how cancer cells invade and metastasize, potentially leading to therapies targeting this mechanism.

Note-taking jurors influence verdicts, study finds

Researchers found that note-taking during trials enhances jurors' recall of critical evidence and influences verdicts. Jurors with faster handwriting speed, higher short-term memory capacity, and better sustained attention remembered more incriminating evidence, leading to a greater likelihood of finding the defendant guilty.
