Ancient Viruses Lurk In Frozen Caribou Poo

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

Dairy scientist targets heat-resistant microbes

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

Three Irish Teens Win Google Science Fair Using Bacteria to Grow Food

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

The bug that lost a few genes to become Black Death

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

Adhering To The 'Replicon Model' The Sloppy Way

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

Viruses as a Cure

When we talk about viruses, usually we focus on the suffering caused by Ebola, influenza and the like. But our bodies are home to trillions of viruses, and new research hints that some of them may actually be keeping us healthy.

“Viruses have gotten a bad rap,” said Ken Cadwell, an immunologi... Read More

A Snippet: One Fungus, Two Bacteria

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 prepackage beneficial microbes in their seeds

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

Six to Tango

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

From the archives: life at 90°C

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

Delaying ART in Patients with HIV Reduces Likelihood of Restoring CD4 Counts

A larger percentage of patients with human immunodeficiency virus (HIV) achieved normalization of CD4+ T-cell counts when they started antiretroviral therapy (ART) within 12 months of the estimated dates of seroconversion (EDS) rather than later, according to a report published online by JAMA In...

Facilitation of horizontal transfer of antimicrobial resistance by transformation of antibiotic-induced cell-wall-deficient bacteria

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

Progress in the fight against harmful fungi

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

US Travelers Return Home With Tropical Disease. Will It Spread In The States?

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

SA vaccine cuts bacteria to size

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

The Result of the Microbiome Poll

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

A Cheap, Promising Way to Filter Water: Through A Twig

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

How do they make it work? Genomic Revelations on a Bacterial Consortium

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

Study Shows Bed Bugs Can Transmit Parasite that Causes Chagas Disease

The bed bug may be just as dangerous as its sinister cousin, the triatomine, or “kissing” bug. A new study from Penn Medicine researchers in the Center for Clinical Epidemiology and Biostatistics demonstrated that bed bugs, like the triatomines, can transmit Trypanosoma cruzi, the parasite that ...
