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.

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
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

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
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
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
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
Each year in the UK, bacterial infections cause around 6,000 cases of a severe eye condition known as microbial keratitis - an inflammation and ulceration of the cornea that can lead to loss of vision. The use of contact lenses has been identified as a particular risk factor for microbial kerati... Read More
A compound found in soybeans can be used in new treatments to inhibit the deadly HIV infection, scientists claim. Read More
Bacteria has the virtue (and sometimes the vice) of being able to grow at incredible speeds—some strains can double in cell count in as little as four minutes. Fernan Federici, a postdoctoral student at the University of Cambridge, is pioneering the art of capturing the split-second process. And... 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
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
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...

From a bacteria’s perspective the environment is one big DNA waste yard. Researchers have now shown that bacteria can take up small as well as large pieces of old DNA from this scrapheap and include it in their own genome. This discovery may have major consequences – both in connection with resi... Read More
Despite major efforts to keep operating rooms sterile, surgical wound infections remain a serious and stubborn problem, killing up to 8,200 patients a year in the U.S. A study by Columbia University Medical Center (CUMC) researchers suggests that narrow-spectrum ultraviolet (UV) light could dram...

Going barefoot in parts of Africa, Asia, and South America contributes to hookworm infections, which afflict an estimated 700 million of the world’s poor. The parasitic worm lives in the soil and enters the body through the feet. By feeding on victims’ blood, the worms cause anemia and, in child... Read More
