  • Scientists Use Rooster Testes to Learn How the Body Fights Viruses
    Our bodies are constantly under siege by foreign invaders; viruses, bacteria and parasites that want to infiltrate our cells. A new study in the journal eLife sheds light on how germ cells - sperm and egg - protect themselves from these attackers so that they can pass ...More

  • Research Shows Some Viruses Can Infect Even After Major Mutations
    Portland State University researchers have found that only about half the genes in a specific virus affecting single cell organisms is needed to infect a host. This means the virus can undergo major mutations without losing its ability to survive and infect. The research, ...More

  • Cross-Species Jumps May Play Unexpectedly Big Role in Virus Evolution
    Tanglegrams of rooted phylogenetic trees for each virus family. Courtesy of Geoghegan JL, et al. (2017)   On occasion, a virus may jump from one host species to another and adapt to the new host. Such cross-species transmission happens more often than expected, ...More

  • New Link Found Between Sex and Viruses
    Sexual reproduction and viral infections actually have a lot in common. According to new research, both processes rely on a single protein that enables the seamless fusion of two cells, such as a sperm cell and egg cell, or the fusion of a virus with a cell membrane. The ...More

  • Rice University Study Probes Microbe, Virus Co-Evolution
    A Rice University study suggests that researchers planning to use the CRISPR genome-editing system to produce designer gut bacteria may need to account for the dynamic evolution of the microbial immune system. CRISPR is an acquired immune system that allows bacteria and ...More

  • Decision-Making Process of Viruses Could Lead to New Antibiotic Treatments
    Humans face hundreds of decisions every day. But we're not alone. Even the tiniest viruses also make decisions, and scientists are researching how they do so, to help lead to better treatments for some diseases. In a study published Feb. 6 in the journal Nature ...More

  • Model Shows How Viruses Enter Intestine
    Using immature stem cells to create a miniature model of the gut in the laboratory, researchers at Washington University School of Medicine in St. Louis and the University of Pittsburgh have determined how infection-causing enteroviruses enter the intestine. ...More

  • Scientists Discover Critical Antiviral Role of Biological Molecule
    Scientists have discovered that a biological molecule important in cell growth (STAT3) is also critical in protecting us against infection - so much so that we would be unable to fight the common flu virus without it. Their discovery could pave the way to the development of ...More

  • Nanoparticle Exposure Can Awaken Dormant Viruses in the Lungs
    Nanoparticles from combustion engines can activate viruses that are dormant in in lung tissue cells. This is the result of a study by researchers of Helmholtz Zentrum München, a partner in the German Center for Lung Research (DZL), which has now been published in the ...More

  • Retroviruses are Ancient, Research Finds
    Retroviruses, the family of viruses that includes HIV, are almost half a billion years old, according to new research by scientists at Oxford University. That's several hundred million years older than previously thought and suggests retroviruses have ancient marine ...More
