Sharing COVID-19 experiences can increase vaccination rates

A Rutgers study found that people who know someone who became ill with COVID-19 or died from the disease are twice as likely to receive a COVID-19 vaccine. The study also found that essential workers and those with better health status were more likely to get vaccinated.

The nutrient that cancer cells crave

Researchers found that arginine levels are limited in human cancers, prompting cancer cells to manipulate proteins to take up the amino acid. Starving cancer cells of arginine may lead to mutations that make them more recognizable to the immune system.
