Henipavirus RNA found in African Bats

A new study in PLoS suggests that positive tests for Henipaviruses in African Straw-colored fruit bats in Ghana may indicate that one of the most pathogenic virus genera known in humans that is usually found in Australia and Asia may also be endemic in Africa.

PloS Abstract:

Henipaviruses... Read More

Stress Signals Link Pre-existing Sickness With Susceptibility To Bacterial Infection

Mitochondrial diseases disrupt the power generating machinery within cells and increase a person's susceptibility to bacterial infection, particularly in the lungs or respiratory tract. A new study published in Disease Models & Mechanisms, shows that infection with the pneumonia causing bacteria... Read More

Pregnant women 1st in line for swine flu vaccine

A government panel has recommended that certain groups be placed at the front of the line for swine flu vaccinations this fall, including pregnant women, health care workers, and children six months and older. Read More

Swine Flu Shot in U.S. May Rely on Emergency Use of Additives

Swine flu vaccine makers may rely on a U.S. emergency declaration to use experimental additives made by GlaxoSmithKline Plc and Novartis AG to boost a limited supply of shots that will be available to fight the pandemic.

The ingredients, known as adjuvants, may be added for the first time to... Read More

Researchers Develop New Geobacter Microbe Strain to Produce More Electricity, Open New Applications

In their most recent experiments with Geobacter, the sediment-loving microbe whose hairlike filaments help it to produce electric current from mud and wastewater, Derek Lovley and colleagues at the University of Massachusetts Amherst supervised the evolution of a new strain that dramatically inc...

'Microfluidic Palette' May Paint Clearer Picture of Biological Processes

The masterpieces that spring from the talents of Rembrandt, Van Gogh and other artists often begin with the creation of a gradient of colors on a palette. In a similar manner, researchers at the National Institute of Standards and Technology have created an innovative device called the “microflu... Read More

Coming Soon: Tuberculosis Detection with a Chip?

Many of the new techniques based on nanotechnology that have been developed for faster and more sensitive detection of pathogens fail in day-to-day clinical use because they require complex sample preparation or measurement equipment, or simply cannot keep up with the large sample throughput in ...

Bacteria simplifies cellulosic ethanol production

Bacteria found in sweet gum wood may improve the preprocessing steps for cost-effective production of cellulosic ethanol.

JDR-2, a strain of the wood-decaying bacteria Paenibacillus, can break down and digest hemicelluloses, which in traditional cellulosic ethanol production is broken down by... Read More

An American Girl Traped in China's Swine Flu Dragnet

Hundreds of Americans suspected of carrying H1N1 have been quarantined in China this summer. Here is a transcript from one American family between the mother and her daughter who was caught up in China's swine flu dragnet this summer. The authors are Sheryl Gay Stolberg, White House corresponden... Read More

New test will help determine the right antibiotics required to treat serious, chronic infections

A new test developed by Edmonton-based Innovotech™ Inc. will now allow doctors to more accurately identify the right antibiotics required to treat serious, chronic infections such as Cystic Fibrosis that are biofilm based. With more than 80 per cent of infections in the developed world caused by... Read More

First genetically-engineered malaria vaccine to enter human trials

Walter and Eliza Hall Institute scientists have created a weakened strain of the malaria parasite that will be used as a live vaccine against the disease. The vaccine, developed in collaboration with researchers from the US, Japan and Canada, will be trialled in humans from early next year.

Microbe Evolution Gets a Push

Improved DNA sequencing technology is making reading genomes faster and cheaper every day. But modifying genes in microbes and other organisms still requires slow and painstaking effort. Now, researchers report that they've come up with a new way to modify the genomes of billions of microbes sim... Read More

Can Good Bacteria Really Fight the Flu?

Cold and flu sufferers, there may be a way to head off those irritating symptoms before they cause you to miss work or school.

New evidence suggests that probiotics -- good bacteria that can aid immune function -- can have a preventive effect for cold and flu viruses.

In a study sponsored... Read More

Natural Born Killers: How The Body's Frontline Immune Cells Decide Which Cells To Destroy

The mechanism used by 'Natural Killer' immune cells in the human body to distinguish between diseased cells, which they are meant to destroy, and normal cells, which they are meant to leave alone, is revealed in new detail in research published July 28 in PLoS Biology.

Understanding how this ... Read More

Swine flu threat greater than terrorism, says UK's Home Secretary
