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.
Initial... Read More
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
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
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

It’s now much easier to pinpoint biological hot spots in the world’s oceans where some inhabitants are smaller than, well, a pinpoint.
Researchers have built a device that can count and classify microscopic algae called phytoplankton that range in size from one to hundreds of microns—the smal... Read More
Some bacteria grow electrical hairs, known as nanowires, that let them link up in big biological circuits.The discovery suggests that microbial colonies may survive, communicate, and share energy in part through electrically conducting hairs.
The finding is reported this week in Proceedings ... Read More
The subject of this year’s top microscope photo in the 36th annual Nikon Small World competition looks more like neon suspension bridges or sailboats than what it really is: mosquito heart muscle magnified 100 times.
The image, which used flourescence technology to highlight different parts o... Read More
Just about a month ago, the disease-geek world was riveted by news of the “Indian superbug“: common bacteria carrying a newly recognized gene that confers profound multi-drug resistance, and that was linked to travel between Europe and South Asia, especially for medical tourism.
The gene, whi... Read More
