Bar code devised for bacteria that causes tuberculosis
Doctors and researchers will be able to easily identify different types of tuberculosis (TB) thanks to a new genetic barcode devised by scientists. To help identify the different origins and map how tuberculosis moves around the world, spreading from person to person through the air, the research team studied over 90,000 genetic mutations.

Scientists create renewable fossil fuel alternative using bacteria
Researchers have engineered the harmless gut bacteria E.coli to generate renewable propane. The development is a step towards commercial production of a source of fuel that could one day provide an alternative to fossil fuels. Propane is an appealing source of cleaner fuel because it has an existing global market.

Growing mushrooms in diapers
Mexico is the third largest consumer of disposable diapers globally, which led to a Mexican scientist to design a technology capable of degrading the product materials by the mushroom Pleurotus ostreatus.

War between bacteria, phages benefits humans
In our battle with cholera bacteria, we may have an unknown ally in bacteria-killing viruses known as phages. Researchers report that phages can force cholera bacteria, even during active infection in humans, to give up their virulence in order to survive.

New way to diagnose malaria by detecting parasite's waste in infected blood cells
A technique that can detect malarial parasite's waste in infected blood cells has been developed by researchers. "There is real potential to make this into a field-deployable system, especially since you don't need any kind of labels or dye. It's based on a naturally occurring biomarker that does not require any biochemical processing of samples" says one of the senior authors of a paper.

Discovery reveals how bacteria distinguish harmful vs. helpful viruses
Viruses can kill bacterial cells or, under the right circumstances, lend them helpful genes that the bacterium could harness to, say, better attack its own hosts. Experiments have now revealed that one type of bacterial immune system can distinguish viral foe from friend, and it does so by watching for one particular cue.

Factor in naked mole rat's cells enhances protein integrity
A factor in naked mole rat cells could be one of the secrets to how the rodent defies aging, researchers say. Naked mole rats, which burrow through underground tunnels in their native East Africa, are nearly hairless rodents. They live as long as 32 years. Naked mole rats maintain cancer-free good health and reproductive potential well into their third decade of life.

Surprising discovery: HIV hides in gut, evading eradication
Some surprising discoveries about the body's initial responses to HIV infection have been made by researchers. One of the biggest obstacles to complete viral eradication and immune recovery is the stable HIV reservoir in the gut. There is very little information about the early viral invasion and the establishment of the gut reservoir. “We want to understand what enables the virus to invade the gut, cause inflammation and kill the immune cells,” said the study's lead author.

Efficacy of new gene therapy approach for toxin exposures shown in mouse study
Gene therapy may offer significant advantages in prevention and treatment of botulism exposure over current methods, new research shows. "We envision this treatment approach having a broad range of applications such as protecting military personnel from biothreat agents or protecting the public from other toxin-mediated diseases such as C. difficile and Shiga toxin-producing E. coli infections," said the lead researcher.

Vaccine for Ebola? Experts answer questions
To learn more about this outbreak and the creation of new human vaccines, infectious disease experts who have led vaccine studies for such global pathogens as cholera, West Nile virus, dengue, typhoid fever and anthrax speak to reporters and answer questions.
