Netting the NET: An anorexia nervosa gene is caught!

A study published in Molecular Psychiatry found a genetic link between the NET protein, which regulates norepinephrine levels, and an increased risk of restrictive anorexia nervosa. The discovery could lead to new treatments for this devastating illness, which has the highest death rate among psychiatric disorders.

New method of DNA testing promises to transform medical diagnostics

Researchers have developed a new DNA testing method using water-soluble conjugated polymers and peptide nucleic acid probes, which can detect specific DNA sequences at much lower concentrations. This approach significantly reduces the cost of diagnostics, especially in poorer countries where access to treatment is limited.

First drug developed for widespread use against botulism

A new drug has been developed to combat botulism by potently neutralizing the toxin. The antibody cocktail is capable of binding to a different part of the toxin molecule, blocking more of the toxin surface than single antibodies. This approach could be scaled up for mass production and stockpiling to prevent or treat botulism.

Size matters

A new model predicts that an animal's body size determines how often it encounters food in its environment. The researchers found that larger animals have bigger home ranges due to their ability to perceive and average over different scales of resource availability.
