Say what you will about our other vices, human beings did not invent cheating. Microbes have been doing it for billions of years. You see, for microbes, cheating can sometimes be an evolutionary advantage. And this can cause it to get out of hand really quickly.

This episode: Ants teaming with bacteria help defend plants from bacterial pathogens!
(9.4 MB, 10.2 minutes)
Bacteria have developed countless strategies to hide themselves in order to evade attack by the immune system. In the body, Salmonella bacteria use macrophages as host cells to ensure their survival and to be able to spread within the body. Their survival strategy is to nestle into a vacuole wit... Read More
The tropical disease malaria is caused by the Plasmodium parasite. For its survival and propagation, Plasmodium requires a protein called actin. Scientists of the Helmholtz Centre for Infection Research (HZI) in Germany used high-resolution structural biology methods to investigate the different... Read More
Antibiotics improve growth in children at risk of undernourishment in low and middle income countries, according to researchers at McGill University who have just conducted a research literature review on the subject. Their results, published in the British Medical Journal, suggest that the youn... Read More
A new genetic analysis revealing the previously unknown biodiversity and distribution of thousands of fungi in North America might also reveal a previously underappreciated contributor to climate change. Pine forests are chock full of wild animals and plant life, but there's an invisible machine... Read More
Scientists have uncovered a new way the immune system may fight cancers and viral infections. The finding could aid efforts to use immune cells to treat illness. The research, in mice, suggests that some organs have the immunological equivalent of “neighborhood police” – specialized squads of de... Read More
A scientist with a swab and a microscope could tell what school you went to. Trillions of microbes live in and on our body. We don’t yet fully understand how these microbial ecosystems develop or the full extent to which they influence our health. Some provide essential nutrients, while others c... Read More
Mothers give a newborn baby a gift of germs -— germs that help to kick-start the infant’s immune system. But antibiotics, used to fight bacterial infection, may paradoxically interrupt a newborn’s own immune responses. A new animal study by neonatology researchers at The Children's Hospital of P...

Raw oysters, so good with hot sauce, increasingly can carry something even more unsettling to the stomach: A bacteria linked to vomiting, diarrhea and pain.
Infections with vibrio, a saltwater-based bacteria that can pool in shellfish, jumped 75 percent last year from 2006-2008, the U.S. Cent... Read More
A major French biomedical research body, the Pasteur Institute, have launched an investigation into the disappearance of some 2,300 test tubes containing samples of the SARS virus. The loss was discovered during an inventory.
The Pasteur Institute filed a so-called 'complaint against X' on Mo... Read More
At least eight Ebola patients in Guinea have beaten the odds. They have recovered and been sent home. In past outbreaks, the death rate has been as high as 90 percent. In Guinea so far, about 60 percent of the 157 suspected cases have ended in death.
The first seven to 10 days after infection... Read More
In order to survive, organisms produce small molecules known as ‘primary metabolites’ which help it to grow, develop and reproduce. Examples include nucleic acid used to make DNA, amino acids to make proteins, and simple sugars. Once the organism is established it will often start to produce ‘se... Read More

In 2004, the rebel geneticist Craig Venter took a sailing trip to Bermuda and, unable to resist doing a little research on the side, hauled up 50 gallons of the Sargasso Sea and began trawling it for DNA. It looked for all the world like cold, sterile saltwater, but Mr. Venter h... Read More
As an educator and researcher at a small liberal arts institution, my success is measured (to me) in watching former students from my classroom and laboratory go on to do great things after graduation. Here, I share some great information about (and by) a former student of mine, Franny Gilman, ... Read More
HOUSTON – (April 16, 2014) – An international research team led by Cesar A. Arias, M.D., Ph.D., at The University of Texas Health Science Center at Houston (UTHealth) has identified a new superbug that caused a bloodstream infection in a Brazilian patient. The report appeared in the April 17 iss... Read More
(Reuters) - An Ebola outbreak blamed for 135 deaths in West Africa in the past month was not imported from Central Africa but caused by a new strain of the virus, a study in a U.S. medical journal said, raising the specter of further regional epidemics. The spread of Ebola from a remote corne... Read More
University of Michigan microbiologist Pat Schloss, Ph.D., describes latest findings from Human Microbiome Project. Based on their findings in today’s Nature, there is no single healthy microbiome. Rather each person harbors a unique and varied collection of bacteria that’s the result of life his... Read More
