Washington, DC—Researchers from Children’s National Medical Center have found that an alternate, “escape” replication process triggered by apoptosis—the process of cell death or “cell suicide”—appears to be common in human herpesviruses (HHV). The findings have implications for better understand... Read More
Noninvasive method could enable rapid diagnosis in humans without need for blood tests. Breath analysis may prove to be an accurate, noninvasive way to quickly determine the severity of bacterial and other infections, according to a UC Irvine study appearing online today in the open-access journ...

Scientists fear the mosquito-borne virus, Chikungunya, which has infected tens of thousands of people in Papua New Guinea, could spread to Australia.
The virus, which originated in Africa, is similar to dengue and causes debilitating joint pain, rashes and fever.
Amid an outbreak of the vi... Read More
Researchers have developed a system that concentrates foodborne salmonella and other pathogens faster than conventional methods by using hollow thread-like fibers that filter out the cells, representing a potential new tool for speedier detection.
The machine, called a continuous cell concent... Read More
Researchers suspect H7N9 virus is in bird markets as human cases rise rapidly. Virologists know its name: H7N9. What they don’t yet know is whether this novel avian influenza virus — first reported in humans in China less than two weeks ago — will rapidly fizzle out, become established in animal... Read More
On October 25, JoVE, the Journal of Visualized Experiments will publish a novel technique to confront the problem of antibiotic resistance. According to Dr. Joseph Ndieyira, one of the developers involved in the technique, "The use of this technology will allow scientists to understand how antib... Read More
Princeton Professor David Botstein pledges funds awarded to him from 2013 Breakthrough Prize in Life Sciences
Cold Spring Harbor, NY – Dr. David Botstein, until recently director of Princeton’s Lewis-Sigler Institute announced today his decision to donate $400,000 to four U.S. academic instit... Read More
For a while, Adam Martiny and some of his fellow scientists had suspected something was not right in how researchers understand the oceans. The object of their suspicion was something called the Redfield ratio, a principle stating that, when nutrients are not limiting, ocean microorganisms alway... Read More
Researchers from the University of Missouri School of Medicine have found a more accurate method to screen for bacterial meningococcal infection in its early stages, when it's hardest to detect. According to the researchers, the method for diagnosis could save lives by getting patients treatment... Read More
A clinical study published in the Lancet Infectious Diseases shows for the first time that an oral cholera vaccine (ShancholTM) provides sustained protection against cholera in humans for up to five years. The study showed the vaccine had a protective efficacy of 65% over a five-year period. The... Read More
Researchers from Boston Medical Center (BMC) and Boston University School of Medicine (BUSM) have identified obesity as a possible risk factor for clostridium difficile infection (CDI). These findings, which appear online in Emerging Infectious Diseases, may contribute to improved clinical surve... Read More
The gastropod mollusc Scaphander lignarius —a marine invertebrate found in North Atlantic and Mediterranean water— is the first organism, besides bacteria, in which the biosynthesis of lignarenones, organic molecules involved in organism’s chemical defence, has been identified. This is one of th... Read More
Finding the gene that gives barley resistance to leaf rust could benefit people who rely on the crop for food and beer.
Researchers have discovered that the gene Rph20 provides resistance to leaf rust in some barley variety adult plants.
“Leaf rust is a fungal disease that could destroy al... Read More
Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon. Researchers at the University of Massachusetts, Amherst report their findings at the 113th General Meeting of the A... Read More
Vibativ (telavancin) has been approved by the FDA to treat HABP/VABP (hospital-acquired ventilator-associated bacterial pneumonia) caused by Staphylococcus aureus. The FDA (Food and Drug Administration) added that telavancin should only be used when other treatments are not appropriate.
Telav... Read More
Some bacteria can harness frozen water as a weapon, using special proteins embedded in their outer membranes to help ice crystals form. Triggering frost formation, the bacteria then invades through the damaged tissues of plants. Now, scientists have observed this bacteria's ability for the first... Read More
Virologist John Holland passed away on 11 October 2013. I asked former members of his laboratory for their thoughts on his career and what he meant to them. Read More
We often ignore what we cannot see, and yet organisms below the soil's surface play a vital role in plant functions and ecosystem well-being. These microbes can influence a plant's genetic structure, its health, and its interactions with other plants. A new series of articles in a Special Sectio... Read More
If you think cold and flu season is tough, trying being an infant. A new research finding published in the November 2013 issue of the Journal of Leukocyte Biology sheds new light on why newborns appear to be so prone to getting sick with viruses—they are born without one of the key proteins need...

In 2008 researchers from the University of Southern Denmark showed that the drug thioridazine, which has previously been used to treat schizophrenia, is also a powerful weapon against antibiotic-resistant bacteria such as staphylococci (Staphylococcus aureus).
Antibiotic-resistant bacteria is... Read More
