Bacteria-infecting viruses bind mucosal surface and protect from disease
Mucosal surfaces protect organisms from external stressors and disease. Bacteriophages, viruses that infect bacteria, have been shown to preferentially bind to mucosal surfaces. This has been suggested to provide an extra level of immunity against bacterial infections. Researchers at the…
In the war on emerging crop diseases, scientists develop new ‘War Room’ simulations
Farmers rely on seed systems for access to high-quality, disease-free planting material at the start of the season. Good seed systems ensure access to seed for a variety of crops that are affordable and fully available at the start of…

‘Give me the calcium!’ Tulane virus takes over cellular calcium signaling to replicate
Some gastrointestinal viruses need calcium. They need calcium ions to carry out several essential aspects of viral life, such as entry into host cells, genome replication and building new viruses to invade other cells. The cells invaded by viruses also…

Genes from ‘fossil’ virus in human DNA found to be active
Genes from a virus that was stitched into the human genome thousands of years ago are active, producing proteins in the human brain and other tissues, new research suggests. The finding might help explain why people who inherit this “fossil virus” appear to have a higher risk of developing neurodegenerative diseases such as multiple sclerosis and Alzheimer’s.
