A careful examination of frozen caribou poop has turned up two never-before-seen viruses.
The viruses are hundreds of years old: One of them probably infected plants the caribous ate. The other may have infected insects that buzzed around the animals.
The findings prove viruses can survive... Read More
A trio of Irish high-schoolers nabbed the top prize in this year's Google Science Fair with a project that speeds up crop growth by tapping into the naturally cozy relationship between soil microbes and plants.
After 11 months of experiments, the three 16-year-olds—Ciara Judge, Émer Hickey, a... 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
Antibiotic resistance is increasing worldwide, and represents a dramatic threat for public health. Antibiotics are a common and universal good, a treasure that we must urgently protect. It is a duty for each citizen of the world. We intend to ask the UNESCO to include the antibiotics in the list... Read More
Sixty years ago Jacob, Brenner and Cuzin devised their 'Replicon Model', inspiring and useful guideline for replication research ever since. According to the model, a 'Replicon' is a genetic element replicated from a single 'Replicator'—replication origin, in modern terms—and replication is trig... Read More
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...

Plants have a symbiotic relationship with certain bacteria. These 'commensal' bacteria help the plants extract nutrients and defend against invaders -- an important step in preventing pathogens from contaminating fruits and vegetables. Now, scientists have discovered that plants may package thei... Read More
One genome at a time can be exciting, but two even more so. I’m not entirely sure why this is, although it may explain our fascination with sex. And what if more than two entities were involved? What if the intimacy were not just between two individual organisms, but between a greater number of ... 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
It is universally accepted that the use of antibiotics will lead to antimicrobial resistance. Traditionally, the explanation to this phenomenon was random mutation and horizontal gene transfer and amplification by selective pressure. Subsequently, a second mechanism of antibiotic-induced antimic... Read More
A group of researchers at the Max F. Perutz Laboratories has created one of the three world's largest gene libraries for the Candida glabrata yeast, which is harmful to humans. Molecular analysis of the Candida glabrata fungus mutations led to the discovery of 28 new genes that are partly respon... Read More
If you happened to be reading state health departments’ outbreak announcements this past weekend, you might have seen something interesting.
(You don’t do this? Hmm.)
Three states — Rhode Island, North Carolina and Tennessee — all said that they have identified residents who have been diag... Read More
South Africa has shown the world that a vaccine against the strains of bacteria that can cause deadly meningitis and pneumonia in children works.
A study published today in the New England Journal of Medicine, to coincide with world Pneumonia Day, records the country's success in reducing pne... 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
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
The "danger zones" in Asia which are vulnerable to a deadly bird flu have been mapped by scientists.
The virus, called H7N9, has infected 433 people mostly in China and has killed 62.
The study, published in Nature Communications, showed parts of Bangladesh, India and Vietnam could easily ... Read More
Do you ever look at a couple and wonder… ‘Why are they together? What does X see in Y. I just don’t get it. Is X in it only for the money’? Who doesn’t at times ponder about such matters? There’s practically an entire economy based on it. However, you didn’t find this article while waiting to ... Read More
DURHAM, NC - Within each strand of DNA lies the blueprint for building an organism, along with the keys to its evolution and survival. These genetic instructions can give valuable insight into why pathogens like Cryptococcus neoformans -- a fungus responsible for a million cases of pneumonia and... 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
