By studying how a virus that infects most people at some point in their lives packages its genetic material during infection, an international collaboration of researchers has made discoveries that help scientists better understand virus-host interactions and may open new avenues for therapies.

UC Davis scientists have uncovered a potential drug target for the development of an effective therapy against the debilitating, chronic form of the bacterial disease brucellosis, which primarily afflicts people in Mediterranean and Middle Eastern countries.
Brucellosis, which affects about 5... Read More
Given the evolutionary ability of microbes to rapidly adapt, the threat of antimicrobial resistance likely will never be eliminated. Today, many factors compound the problem, including the inappropriate use of antibiotics and a dwindling supply of new medicines, leading to a global crisis of ant... Read More
A virus that invaded the genomes of humanity's ancestors millions of years ago now plays a critical role in the embryonic stem cells from which all cells in the human body derive, new research shows.
The discovery sheds light on the role viruses play in human evolution and could help scientis... Read More
As they destroy bacteria very efficiently, plasmas constitute an alternative to chemical disinfectants and potentially to antibiotics, as well. How they achieve this effect has been investigated by biologists, plasma physicists and chemists at the Ruhr-Universität (RUB). Cold atmospheric-pressur... Read More
The head of the World Health Organization warned the world this week of a new virus, awkwardly dubbed MERS-CoV, found in Saudi Arabia.
"Looking at the overall global situation, my greatest concern right now is the novel coronavirus," Margaret Chan said, calling it "a threat to the entire worl... Read More
Six new cases of Heartland virus disease have been identified in residents of Missouri and Tennessee. The cause of this disease appears to be a member of the Phlebovirus genus in the Bunyaviridae family that was first identified in 2009 and appears to be transmitted by the Lone Star tick (Amblyo...

Gastrointestinal parasitic infections, which are worm infections in the intestine, affect nearly one quarter of the world population and have been heavily linked with poverty in poorer regions.
They normally result in a chronic, long-lived infection associated with poor quality of life and he... Read More
Endogenous retroviruses (ERVs) are viruses that at some point in the past inserted themselves into the nuclear genome of a host's germ cell. Once integrated in a germ cell the virus would be passed on from one generation to the next and the endogenous retroviral genome would therefore be inherit... Read More
It is well known that aquatic birds are a major reservoir of influenza A viruses, and that pandemic human influenza virus strains of the past century derive viral genes from this pool. The recent discovery of two new influenza A viruses in bats suggests that this species may constitute another r... Read More
A compound found in soybeans can be used in new treatments to inhibit the deadly HIV infection, scientists claim. Read More
Researchers and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones.
University of Illinois at Urbana-Champaign researchers have developed a cradle and app for the iPhone that uses the phone's buil... Read More
Researchers at the University of Melbourne have discovered that some Indigenous groups will be more susceptible to the effects of the new strain of influenza (H7N9) currently found in China.
Research indicated that some Indigenous people such as in Alaska and Australia displayed limited immun... Read More
Bacterial proteins could alter precipitation patterns and climate-change models.
Proteins can help grow teeth and bones in the body, crops in the ground, and even ice in the atmosphere. Some proteins have an uncanny knack for kick starting ice formation at unusual temperatures, and they have ... Read More

GUECKEDOU, Guinea, April 8 (Thomson Reuters Foundation) - H iccups, say doctors in this remote corner of Guinea, are the final tell-tale sign of infection by the Ebola virus that has killed more than 100 people since an outbreak began this year.
Then come profuse bleeding, circulatory shock a... Read More
Researchers at the UNC School of Medicine have deployed a potential new weapon against HIV – a combination therapy that targets HIV-infected cells that standard therapies cannot kill.
Using mouse models that have immune systems composed of human cells, researchers led by J. Victor Garcia, PhD... Read More
On any given day, one in 25 hospitalized patients - 4 percent - is battling an infection picked up in a hospital or other healthcare facility, according to a new survey by the Centers for Disease Control and Prevention (CDC).
That translates to more than 600,000 hospital patients each year. R... Read More
A study published recently in PLOS ONE authored by Dr. Henry Sun and his postdoctoral student Dr. Gaosen Zhang of Nevada based research institute DRI provides new evidence that Earth bacteria can do something that is quite unusual. Despite the fact that these bacteria are made of left-handed (L)... Read More
A new study from Karolinska Institutet in Sweden finds that testing for human papilloma virus (HPV) allows for longer time between screening tests when compared to cytology-based testing. The study is published in the scientific journal British Medical Journal (BMJ).
Cervical screening progra... Read More
