A four-year EU-funded project has identified new ways of cultivating marine microorganisms and screening them for potentially useful marine bio-compounds. This could have implications for the healthcare, cosmetics and pharmaceutical industries, which are just a few of the sectors that are eager ... 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
Researchers at the University of Virginia School of Medicine studying a potentially deadly parasitic infection have discovered a previously unknown way that human cells are killed, with the parasitic amoeba essentially nibbling cells to death – as a piranha might attack its prey.
Until now, r... Read More
Bravo Randy Schekman!
I strongly support your comments on the tyranny of "impact factors" and I will be pleased to join in efforts to prevent the misuse of these ratings.
Impact Factors have become a symbol of terror for scientists in all disciplines and their use in promotion and other ... Read More
What have we learned?
The various comments confirm that the term microbiome means different things to different people.
Lita points out that in the early days when HMP was formed, the NIH officially defined the human microbiome as “all of the microorganisms and their genes and genomes whic... Read More
Dave Wiechert of Nashville, Illinois, does good business most years cleaning seed for farmers in preparation for planting season. But this year, Wiechert is doing big business after harvest: cleaning fungus off wheat so farmers can sell it.
The "head scab" fungus can produce vomitoxin, a chem... 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
Prokaryotes are by far the most successful superkingdom in terms of both biochemical diversity and the variety of environments conquered. Bacteria can be found living in all kinds of adverse conditions; from high alkaline lakes, to below freezing temperature, to hot volcanic vents which in some ... Read More
Corralling desperados with names like bacillus and paenibacillus will require ingenuity and an arsenal of weapons. These outlaws aren't rustling cattle—they're making milk sour and cheese soft and crumbly.
For more than a century, milk has been heated to kill any bacteria or pathogens that ca... Read More

About 6,000 years ago, a bacterium underwent a few genetic changes. These allowed it to expand its habitat from the guts of mice to that of fleas. Such changes happen all the time, but in this particular instance the transformation eventually resulted in the Black Death that wiped out a third of... Read More
Yale University researchers have determined how a scarce molecule produced by marine bacteria can kill cancer cells, paving the way for the development of new, low-dose chemotherapies.
The molecule, lomaiviticin A, was previously shown to be lethal to cultured human cancer cells, but the mech... Read More
One way to avoid getting sick while traveling is to only eat fruit that you peel yourself, since plants can filter out bacteria and prevent it from traveling throughout their tissues. Well, why not apply this principle to filtering water directly? A team of scientists have done just that, testi... 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
Bacteria could mop up naturally-occurring and man-made leaks of natural gases before they are released into the atmosphere and cause global warming - according to new research from the University of East Anglia.
Findings published today in the journal Nature shows how a single bacterial strai... Read More
We continue our semi-annual ritual and post this quick tour of our featured blog posts published since June 2013.
Microbial ‘Starstuff’. Associate blogger Gemma Reguera tells us how the remnants of a dying star become transmuted into microbial stuff, including cellular structures... Read More
A few weeks ago, I came across a new paper in BioScience called “Natural History’s Place in Science and Society” that contained the following graph.
On the right axis and indicated by the line surrounded by dots is the proportion of introductory biology texts devoted to natural history since ... 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
Scientists have taken the first steps to developing a vaccine for chikungunya — an emerging mosquito-borne virus that has infected more than a half million people in the Western Hemisphere this year. About 600 Americans have brought the virus to 43 states.
The study was small. Only 25 people ... 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
