Researchers have discovered that a type of white blood cell carries a deadly fungus into the brains of HIV positive patients, causing meningitis which kills more than 600,000 people a year. The discovery could lead to more effective ways of tackling the deadly fungus as it infects the human body... 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
Genetic factors could play an important role in whether people survive the Ebola virus, say US scientists.
A study of mice infected with the virus found they showed a number of different symptoms, with 19% remaining unaffected by the disease.
This could explain why some people recover from... Read More
Plants and Microorganisms are the major sources of drugs till date. Most of these "natural products" come from a few genera of soil and marine bacteria that have long been known for their prolific chemistry. The classical process of discovering drugs from microorganisms have two drawbacks- it is... Read More
From November 2010: http://subtledesigner.blogspot.com/
So this year we really tried hard to geek out with the Christmas tree decorations (not that we haven’t done this before). We went with a 'microscopic universe' theme complete with DNA garland (made from pipe cleaners), micro-organism o... Read More
Vanderbilt University researchers have now discovered how intestinal cells build this specialized structure, which is critical for absorbing nutrients and defending against pathogens. The findings, published April 10 in the journal Cell, reveal a role for adhesion molecules in brush border assem... Read More
While I was working on the “H1N-What?” post, I also knew there would soon be questions about MERS (Middle East Respiratory Syndrome), just as there were about SARS. So here are the essentials of what we know and don’t know about MERS—which has just been reported in the U.S.—as well as intriguing... Read More
An international team of scientists has identified the precise biochemical key that wakes up the body’s immune cells and sends them into action against invading bacteria and fungi.
The patented work, published in Nature today, provides the starting point to understanding our first line of defen... Read More
Scientists working to understand the devastating bat disease known as white-nose syndrome (WNS) now have a new, non-lethal tool to identify bats with WNS lesions —ultraviolet, or UV, light.
If long-wave UV light is directed at the wings of bats with white-nose syndrome, it produces a distinct... Read More
The Human Microbiome Project revealed tens of trillions of microbes residing in and on humans. Now scientists are taking a census of plant microbes—and not just the hundreds of billions found in soils. Distinct microbial communities live inside roots, on leaves and within flowers, and all in all... Read More
A University of Florida research team is cautiously optimistic after finding a possible treatment in the lab for citrus greening, a disease devastating Florida’s $9 billion citrus industry. It is the first step in a years-long process to bring a treatment to market.
Claudio Gonzalez and Graci... Read More
A common plant puts out a welcome mat to bacteria seeking to invade, and scientists have discovered the mat's molecular mix. The study published this week in the Proceedings of the National Academy of Sciences reveals new targets during the battle between microbe and host that researchers can ex... Read More
Although natural selection is often thought of as a force that determines the adaptation of replicating organisms to their environment, Harvard researchers have found that selection also occurs at the level of neurons, which are post-mitotic cells, and plays a critical role in the emergence of A...

We need to understand how diverse communities of microbes interact, but doing so in the gut is hard. Why not turn to a model system, where diverse microbial communities interact, but in an environment that’s easier to study? We have a long history of using model systems in biology – the mice I m...

Beautiful metallic colonies of E. coli growing on Endo agar which is being used mostly for differentiation and isolation of Enterobacteriaceae strains.
How often have you heard of two or more bacterial species coexisting within the same cell of a host? It’s known to happen with some frequency in some amebas, insects and other invertebrates (including the strange case of the mealybug bacteria, which have an endosymbiotic bacterium that carries a...

Researchers at Princeton have discovered that cytomegalovirus manipulates a process called fatty acid elongation, which makes the very-long-chain fatty acids necessary for virus replication. Published in the journal Cell Reports on March 3, the research team identified a specific human enzyme--e... Read More
Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome, new research shows.

Potentially toxic microbes which pose a threat to our drinking water have undergone a dramatic population explosion over the last 200 years as a result of pollution, research involving experts from The University of Nottingham has found. The study, published in the journal Ecology Letters, looke... Read More
The first of a group of 10 American aid workers who may have come into contact with the Ebola virus in Sierra Leone were evacuated on Saturday, American government and aid officials said. They will be the largest group of Americans to have returned home over fears of exposure to the virus since ... Read More
