This episode: Bacteria have effects on brain development!
Early Earth lacked an ozone layer to act as a shield against high-energy solar radiation, but microbes flourished by adapting to or finding other forms of protection from the higher ultraviolet radiation levels. Now researchers have begun testing modern microbes to see if they could act as pione... Read More
Each of us carries a unique collection of trillions of friendly microbes in our intestines that helps break down food our bodies otherwise couldn’t digest.
This relationship between humans and their microbes is generally a healthy one, but changes to the mix of microbes in the digestive tract... Read More
Our search for life beyond Earth could take us down the road to a shocking look into the mirror -- a climax straight out of a Twilight Zone plot.
A team of researchers at MIT is proposing to apply forensic science testing on the Martian surface. Specifically, the task would be to do DNA and R... Read More
With 6 dead and over 700 cases in just the last two weeks, the rapidly rising numbers are leading experts to think that the latest outbreak could kill more than the 131 who died in the original 2009 emergence.
The outbreak of the AH1N1 flu virus affecting Venezuela since March 17 has caused s... Read More
An outbreak of A/H1N1 influenza in Venezuela has infected 482 people and killed three this year, the country’s health ministry reported on Wednesday.
The outbreak of the disease also known as swine flu started in the southeastern state of Merida on March 17 and spread to the capital Caracas... Read More
Researchers have identified a new ally in the war against tooth decay: an enzyme produced by a mouth bacterium that prevents plaque formation. The finding could eventually lead to the development of toothpaste that harnesses the body's own plaque-fighting tools.
The human mouth is awash with ... Read More
Flu activity in the United States continues to tail off, though newly reported pediatric deaths were twice as high as the week before, the US Centers for Disease Control and Prevention (CDC) said today.
The percentage of deaths from pneumonia and flu, however, remained above the epidemic leve... Read More
David Livermore is in a race against evolution. In his north London lab, he holds up an evil-smelling culture plate smeared with bacteria. This creamy-yellow growth is the enemy: a new strain of germs resistant to the most powerful antibiotics yet devised by humankind.
Out on the streets, Ste... Read More
Science writer Carl Zimmer writes a masterful blog piece tracing the history of the study of ecosystems, from lakes to the human microbiome. Just one interesting fact: In their lifetimes, individual humans will produce about five elephants worth of microbes. Read More
El podcast del Microbio Nº185 deals with the discussions inside WHO about the fate of the last vials with smallpox virus. E... Read More
In a forest of tubes eight metres high in eastern Spain scientists hope they have found the fuel of tomorrow: bio-oil produced with algae mixed with carbon dioxide from a factory.
The project, which is still experimental, has been developed over the past five years by Spanish and French resea... Read More
"Who has more bacteria in their navel -Carl Zimmer of The Loom or Peter Aldhous of NewScientist? The swabs have been taken, and the cultures were grown." - Miss Cellania
In late February, Peter Aldhous visited Rob Dunn's lab at North Carolina State University in Raleigh, where a team led by J... Read More
Last week we discussed the second known virophage, but we didn’t have any explanation of why such viruses might evolve. This week we have the discovery of a third virophage, hints of many more, and a hypothesis for what they might be doing in the global ecosystem. Read More

It is no wonder the roads of Scunthorpe are peppered with potholes.
That is because boffins have revealed residents in the town are having the ground eaten from under their feet by greedy bacteria.
Scunthorpe is built on tonnes of iron ore that experts believe could supply the steel-making... Read More
Electronic faucets may be touch-free, but they are far from germ-free. In a new study, researchers at The Johns Hopkins School of Medicine report finding higher levels of disease-carrying bacteria on hands-free faucets compared to conventional, manually operated faucets. Their discovery led to t... Read More
Researchers from the University of Pittsburgh and Stanford University discovered that a supposedly inactive protein actually plays a crucial role in the ability of one the world's most prolific pathogens to cause disease, findings that suggest the possible role of similarly errant proteins in ot...

Toxoplasma gondii, an obligate intracellular parasite of the phylum Apicomplexa, has the unusual ability to infect virtually any warm-blooded animal. It is an extraordinarily successful parasite, infecting an estimated 30% of humans worldwide. The outcome of Toxoplasma infection is highly depend... Read More
In what could be a potential breakthrough in the battle against AIDS and a major development in the rational design of new drugs, scientists have engineered a new protein that prevents the virus from entering cells. This protein is based on a naturally occurring protein in the body that protects... Read More
