Few Chicken Products with Highly Virulent Salmonella Strains Responsible for Most Illnesses

Raw poultry is one of the main causes of Salmonella poisoning, which affects thousands of people in the U.S. every year. A new study from the University of Illinois Urbana-Champaign shows that few products with high levels of very virulent Salmonella strains are responsible for most of the illnesses from raw chicken parts.

Liver-produced hormone protects mice against the harmful effects of intoxication

A shot of a liver-produced hormone called FGF21 sobered up mice that had passed out from alcohol, allowing them to regain consciousness and coordination much faster than those that didn't receive this treatment, UT Southwestern researchers report in a new study.

Detecting multiple food poisoning bacteria based on color differences in scattered light from metals

Osaka Metropolitan University scientists have developed a simple, rapid method to simultaneously identify multiple food poisoning bacteria, based on color differences in the scattered light by nanometer-scaled organic metal nanohybrid structures (NHs) that bind via antibodies to those bacteria.

Researchers analyze how cannabis cells make cannabinoids

Plant biologists have outlined the elevated “hacks” that cannabis cells use to produce cannabinoids (THC/CBD) for the first time. Although many biotechnology firms are currently attempting to engineer THC/CBD outside of the plant in yeast or cell cultures, it is still unclear how the plant does it innately.
