Researchers apply a new experimental approach to visualize the turbulent motion of swimming bacteria and propose a minimal model that captures their observations.
Bacteria are among the oldest and most abundant living species on Earth, and their activity influences the planet’s environmental ... Read More
As many San Franciscans have noticed, sourdough bread stays fresher longer than the regular stuff. Sourdough’s extended freshness is due to extra fermentation that traps more moisture in the dough. But now we know that sourdough’s longevity is also because it can ward off mold. Because bacteria ... Read More
An important predictor of the severity of respiratory syncytial virus (RSV) in infants may be what their mothers ate during pregnancy.
Fernando Polack, M.D., Cesar Milstein Professor of Pediatrics, is lead author of an article in the American Journal of Respiratory and Critical Care Medicine... Read More
What draws a mosquito to bite its host has long been studied from the perspective of the victim—uncovering which smells and chemicals lure the insect in. But researchers at Rockefeller's Laboratory of Neurogenetics and Behavior, headed by Robin Chemers Neustein Professor Leslie Vosshall, are aim... Read More
The first description of the 4-million-atom structure of the HIV’s capsid, or protein shell, could lead to new ways to fight the virus. The findings are highlighted on the cover of the May 30 issue of Nature.
“The capsid is critically important for HIV replication, so knowing its structure in... Read More
An outbreak of high-pathogenicity avian influenza H7N7 virus that took place on 255 poultry farms in the Netherlands during 2003 has been used to provide clues about the current avian influenza H7N9 viruses in China. During the Dutch outbreak 453 humans showed symptoms of illness and 89 were con... Read More
I have been asked recently to write an article, somewhat along the lines of this one but longer, and with a somewhat different angle, asking a little bit different questions: What makes a science blog? Who were the first science bloggers and how long ago? How many science blogs are there? How do... Read More
The Gulf of Mexico may have a much greater natural ability to self-clean oil spills than previously believed, an expert in bioremediation said here today at the 245th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society.
Terry C. Hazen, ... Read More
An alternative treatment for antibiotic-resistant infections that are raising concern nationwide already exists. But there's a big problem. The treatment is not approved for use in the United States.
And it could be a decade or more for the treatment, long used in Russia, former Soviet nation... Read More
The world's longest-running experiments remind us that science is a marathon, not a sprint. Although science is a long-term pursuit, research is often practised over short timescales: a discrete experiment or a self-contained project constrained by the length of a funding cycle. But some investi... Read More
A potentially lethal fungal infection appears to gain virulence by being able to anticipate and disarm a hostile immune attack in the lungs, according to findings by researchers at Duke Medicine.
Defense mechanisms used by the fungus Cryptococcus neoformans enable it to lead to fatal meningit... Read More
Now that the mammalian intestinal microbiome has been promoted to organ status, might not such stately respectability be granted to the gut microbiota of other metazoans? If looking for a worthy candidate for such recognition, one could not do better than to consider the varied communities dwell... Read More
An increasing number of bacteria is evolving antibiotic resistance. Much-feared representatives of this steadily growing group include Staphylococci strains. At this point, multi-resistant forms of the bacterium Staphylococcus aureus - the "hospital germ" known commonly by its acronym, MRSA - ca... Read More
If half of a cell population were coloured white and the other half were coloured black, scientists should think all cells are grey. Conventional methods average over thousands of cells, overlooking any cell-to-cell variability. ETH scientists now measured metabolite levels in single yeast cells... Read More
Seeing how the Hepatitis C virus builds ion channels could help researchers find new drugs to fight the disease. Viruses are masters of minimalist design. With only a simple genome and a handful of proteins, a virus can hijack much more sophisticated cells and mimic many of the intra- and inter-... Read More
Many ladies love their handbags and will spend a lot of money for the latest and greatest, but a new study says what is inside those bags may be covered in germs worse than what you’ll find in the bathroom.
As CBS 2′s Cindy Hsu reported Wednesday, the study said your purse may, in fact, have ... Read More
On May 8th JoVE will publish research that demonstrates how a biosensor can detect antibiotic resistance in bacteria. This new technology is a preliminary step in identifying and fighting superbugs, a major public health concern that has led to more deaths than AIDS in the United States in recen... Read More
Researchers at Tufts University School of Dental Medicine and the Forsyth Institute published a study today that found that a significant proportion of dental bib clips harbored bacteria from the patient, dental clinician and the environment even after the clips had undergone standard disinfecti...

The Supreme Court said human genes isolated by scientists may not be patented, ruling unanimously today in a dispute weighing intellectual property associated with genes known to detect early signs of breast and ovarian cancer.
The dispute concerned a 2009 lawsuit filed by the American Civil ... Read More
Not long ago, Elio said in this blog that predation, a major force in evolution, is somewhat neglected in microbiological circles. The full implications of predation are just beginning to be uncovered as more becomes known about the ecology, physiology, and genomics of predators against microbes... Read More
