People are still debating whether the mRNA from COVID-19 vaccines remains in the body longer than it should. Some say it lingers and causes harm, others say that idea just doesn’t hold up. A new ...

As antibiotic-resistant infections rise and are projected to cause up to 10 million deaths per year by 2050, scientists are looking to bacteriophages, viruses that infect bacteria, as an alternative.

Discover how a tiny RNA molecule serves as a molecular switch in viral infections, providing insights into phage biology.

Researchers have revealed that so-called “junk DNA” contains powerful switches that help control brain cells linked to Alzheimer’s disease. By experimentally testing nearly 1,000 DNA switches in human ...
