'Selfish' genes called introners proven to be a major source of genetic complexity

A new study proves that a type of genetic element called 'introners' are the mechanism by which many introns spread within and between species, also providing evidence of eight instances in which introners have transferred between unrelated species in a process called 'horizontal gene transfer,' the first proven examples of this phenomenon.

New UK law would ban ransomware payments by publicly funded orgs

The British government has announced plans to move forward with a law that would bar public organizations from paying off ransomware attackers. The proposed legislation would add schools, town councils, National Health Service (NHS) hospitals and critical infrastructure managers to a ban which already applies to the national government. The logic behind banning payments is simple. If cybercriminals know a ransomware attack against a UK school or hospital won't get... Read more

Erythritol, a widely used sugar substitute found in many low-carb and sugar-free products, may not be as harmless as once believed. New research from the University of Colorado Boulder reveals that even small amounts of erythritol can harm brain blood vessel cells, promoting constriction, clotting, and inflammation—all of which may raise the risk of stroke.

Dogs trained to detect Parkinson’s disease using scent have shown remarkable accuracy in new research. In a double-blind trial, they identified skin swabs from people with Parkinson’s with up to 80% sensitivity and 98% specificity, even when other health conditions were present. The findings offer hope for a simple, non-invasive diagnostic method using biomarkers that appear long before traditional symptoms, potentially allowing earlier treatment and slowed disease progression.

Scientists have uncovered a surprisingly simple “tissue code”: five rules that choreograph when, where, and how cells divide, move, and die, allowing organs like the colon to remain flawlessly organized even as they renew every few days. Mathematical models showed that manipulating just these parameters faithfully recreates real tissue architecture, hinting that the same code may govern skin, brain, and more. The discovery offers a fresh way to understand healing,... Read more
