Technologies for rapid detection of bacterial pathogens are crucial to maintaining a secure food supply.
Researchers from the School of Science at Indiana University-Purdue University Indianapolis (IUPUI) and the Bindley Bioscience Center at Purdue University have developed a novel approach t... Read More
Did you know that our bodies are home to trillions — yes, trillions — of microorganisms that play a role both in keeping us healthy and making us sick?
Taken together, these teeming communities of bacteria, viruses and fungi make up what's known as our microbiome, and probing its secrets has ... Read More
Personal touch-screen devices – iPads, BlackBerrys and Droids – are now seemingly everywhere, potentially harboring the germs and viruses that turn voices raspy and send noses running.
Want to peek at a digital snapshot, a friend's Facebook status or to show off the latest YouTube video? Best... Read More
New research shows, how like a conjuring trick with interlocking rings, two interlocked pieces of DNA are separated after DNA is copied or repaired.
While reconstituting the DNA repair system of yeast in a test tube, scientists found that a complex of proteins called Sgs1, Top3, and Rmi1 allo... Read More
Intranasal administration of the protein flagellin may activate innate immunity and protect against acute pneumonia say researchers from France. They report their findings in the October 2010 issue of the journal Infection and Immunity.
Streptococcus pneumoniae is a major cause of respirator... Read More
Klassevirus, a new member of the picornavirus family, has recently been discovered in human stool and more specifically linked with pediatric diarrhea. Researchers from the U.S. and abroad detail their findings in the October 2010 issue of the journal Clinical and Vaccine Immunology.

Helicobacter pylori, the bacterium largely associated with gastritis and peptic ulcers in humans, may invade and replicate in gastric epithelial cells say researchers from China. This discovery disputes prior views of H. pylori as a noninvasive pathogen and could offer significant insight into ... Read More
The need to re-formulate the influenza virus vaccine in response to viral antigenic drift and shift makes for complex logistics of vaccine production and administration. Surveillance programs must be conducted each year to identify strains that are likely to predominate and cause disease. Wouldn... Read More
Jeff Fox of Microbe magazine interviews Michael Brennan of Aeras Global TB Vaccine Foundation on efforts to develop a tuberculosis vaccine. Aeras is focusing a substantial portion of its vaccine development strategy and efforts on the venerable but flawed Bacille Calmette-Guerin (BCG) vaccine Read More
Xenotropic murine leukemia virus–related virus (XMRV) has been the subject of many studies since its discovery in 2006, but conflicting reports have created an unclear picture of XMRV's role in human disease. In three recent studies published in the November 15 issue of The Journal of Infectious... Read More
A study of peptide hormones in the brain of a seemingly primitive flatworm reveals the surprising complexity of its nervous system and opens up a new approach for combating a major parasitic disease, researchers report.
The planarian flatworm, Schmidtea mediterranea, is perhaps best known for... Read More
Two studies appearing in the October 14, 2010 New England Journal of Medicine and funded by the National Institutes of Health helped influence the World Health Organization (WHO) to change its guidelines this year for the treatment of HIV infection in certain women and children. The recently up... Read More
A flu vaccine made through a speedier production method appears to be as safe and effective as one produced in the traditional way, a study suggests.
The conventional flu vaccine is produced using chicken eggs to grow the virus, a slow process that makes it hard to quickly boost production in... Read More
Much as an anthropologist can study populations of people to learn about their physical attributes, their environs and social structures, some marine microbiologists read the genome of microbes to glean information about the microbes themselves, their environments and lifestyles.
Using a rela... Read More
Malaysia could be the first country in Asia to use genetically modified mosquitoes to battle a rise in dengue fever, government authorities said Monday. Read More
Bioluminescence is as widespread as it is wild and mysterious. Jack-o'-lantern mushrooms, flashlight fish and fireflies are among the multitude of organisms that bioluminesce. Scientists are still finding previously unknown examples of the phenomenon, especially at sea, where bioluminescent spec... Read More
Psi Wavefunction, an undergraduate in the Department of Botany, University of British Columbia, and the host of the blog Skeptic Wonder: Protists, Memes and Random Musings, has authored a guest post on Small Things Considered that looks at some confusing terminology associated with phylogenies:

Researchers have discovered the crystal structures of pumps that remove heavy metal toxins from bacteria, making them resistant to antibiotics.
The finding offers a better understanding of bacterial resistance to antibiotics that could ultimately help drug researchers develop treatments to co... Read More
