Each year, more than two million people in the United States develop antibiotic-resistant infections, and at least 23,000 of them die as a result, says the first-ever national snapshot of the issue. That toll only rises when other conditions exacerbated by these infections are included in the co... 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
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
Following the September death of a young boy in St. Bernard Parish, La. from a brain-eating amoeba found in household water, state officials have confirmed the same amoeba has been found in a northern Louisiana parish's water. The amoeba, called Naegleria fowleri, which proves deadly if water is... Read More
Badgers are ultimately responsible for roughly half of tuberculosis (TB) in cattle in areas with high TB prevalence, according to new estimates.
However, only around six per cent of infected cattle catch TB from badgers, with onward transmission between cattle herds accounting for the remaind... Read More
Two new studies reveal how US scientists managed to uncover the detailed structure of a protein that plays a key role in HIV infection. The findings offer the kind of in-depth understanding that has been missing in the development of successful vaccines against the AIDS virus.
Using protein e... 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
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
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
Malaria is one of the most important infectious diseases in the developing world, with the absence of a vaccine and the development of parasite resistance to commonly used antimalarial drugs complicating efforts to fight the deadly disease.
The parasite that causes malaria is Plasmodium, whic... Read More
Getting a flu shot cuts the risk of having a heart attack or stroke by more than 50% in people who have had a heart attack, a new study shows.
"We may have identified that the flu vaccine may also be a vaccine against heart attacks," says lead author Jacob Udell, a cardiologist at Women's Col... Read More
Bacteria have a bad reputation, but University of Utah pathologist June L. Round, Ph.D., likes to look at their good side–and for the second time this year she's received a prestigious national award to aid her research into bacteria that actually are good for human health.

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
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
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
The spherical spores produced by the fungus Emericella nidulans are coated in a thin layer of the protein hydrophobin. Hydrophobin ensures that water rolls off the spores. Other fungi, such as mushrooms, also have a layer of hydrophobin on their caps. BASF researchers have succeeded in transferr... 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
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
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
