The most detailed analysis to date of the spread of the H1N1 2009 pandemic influenza virus, known informally as ‘swine flu’, has found that short-range travel was likely the primary driver for the 2009 pandemic in the United States, in contrast with popularly accepted views on the way diseases s...

As many patients know, treating wounds has become far more sophisticated than sewing stitches and applying gauze, but dressings still have shortcomings. Now scientists are reporting the next step in the evolution of wound treatment with a material that leads to faster healing than existing comme... Read More
Researchers at Bigelow Laboratory for Ocean Sciences dug into the last 70 years of peer-reviewed publications about protozoan parasites that infest bivalve mollusks and found that when an organism can be cultured in the laboratory, more papers and greater understanding result. Senior Research S... Read More
Vibrio cholerae was isolated in the capital city Kathmandu , where as it causes cholerae endemic in certain remote parts in the country every year . Vibrio cholerae O1 ogawa serotype was isolated and identified after growth in TCBS agar and subcultured on HIA plate and performed oxidase test (+... Read More
Recently, the American Academy of Microbiology released a new report, Viruses Throughout Life & Time: Friends, Foes, Change Agents that delves into the origin of viruses, the overlooked biological and microbial ecological role of viruses, and how these live forms have contributed to evolution. T... Read More
A virus not known to cause disease kills triple-negative breast cancer cells and killed tumors grown from these cells in mice, according to Penn State College of Medicine researchers. Understanding how the virus kills cancer may lead to new treatments for breast cancer.
Adeno-associated virus... Read More
The technique addresses the problem of hidden reservoirs of HIV in the body, and could herald a new way of battling the viral infection.
Once HIV invades the body, it doesn’t want to leave. Every strategy that scientists have developed or are developing so far to fight the virus – from powerf... Read More
When most people look at soil, they just see dirt. When I look at soil, I see billions of microorganisms crawling atop one another, consuming the dead in a feasting frenzy that stops for nothing save a deep freeze. I see microbes and their enzymes, the digestive juices that break down, transform... Read More
For hospital workers an outbreak of harmful bacteria in the wards is a nightmare, but what gives bacteria nightmares?
Perhaps the prospect of being eaten alive by a kind of viral parasite called a bacteriophage (bacteria eater): unlike antibiotics, which some bacteria have evolved a resistanc... Read More
The joys of anaerobic digestion
One U.K. grocery store plans to power itself using biogas harvested from its own unsold, rotting produce. Yum.
A Sainsbury's store in Cannock in central England is getting access to anaerobic digesters. The store plans to use electricity solely from the dige... Read More
Using two yeasts that have been used to brew tea and beer for centuries, researchers at Fred Hutchinson Cancer Research Center have revealed how reproductive barriers might rapidly arise to create species boundaries. Schizosaccharomyces pombe has been used to brew beer in Africa, whereas its clo... Read More

MIT study finds ocean bacteria follow predictable patterns of daily activity.
We are all creatures of habit, and a new MIT study finds ocean bacteria are no exception.
In a paper published this week in Science, researchers from MIT and elsewhere report that microbes in the open ocean follo... Read More
Growth of Acetobacter pasteurianus on glucose, yeast extract, calcium carbonate, ethanol medium.
Formation of acetic acid from ethanol oxidation is shown by a clear halo around bacterial growth due to dissolution of calcium carbonate.
Organism: Acetobacter pasteurianus. Incubation conditions:... Read More
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.
A new study from MIT materials scientists reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-... Read More
A probiotic that prevents obesity could be on the horizon.
Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice, Vanderbilt University investigators have discovered.
“Of course it’s hard to spec... Read More
Accelerated progress against the global burden of HIV, malaria, and tuberculosis (TB) has been made since 2000 when governments worldwide adopted Millennium Development Goal 6 to combat HIV/AIDS, malaria, and TB. New estimates from a major new analysis show that worldwide, the number of people l... Read More
Nearly 40 years ago, a young Belgian scientist travelled to a remote part of the Congolese rainforest - his task was to help find out why so many people were dying from an unknown and terrifying disease.
In September 1976, a package containing a shiny, blue thermos flask arrived at the Instit... Read More
A UAB research concludes that the Streptococcus mutans, one of the principal bacteria causing dental caries, has increased the changes in its genetic material over time, possibly coinciding with dietary changes linked to the expansion of humanity.
