Hello Professors Racaniello and Despommier,
In TWIP #33, Dr Despommier said that certain parasites do not need receptors to enter cells, while Dr Racaniello then said that all viruses require a receptor for entry. I might be wro... Read More
New research has revealed how infection by a parasitic fungus dramatically changes the behavior of tropical of carpenter ants (species Camponotus leonardi), causing them to become zombie-like and to die at a spot that has optimal reproduction conditions for the fungus. The multinational research... Read More
Genetically modified bacteria could be used in air filters to extract pesticide vapors from polluted air thanks to work by researchers in China published this month in the International Journal of Environment and Pollution.
The bacteria Escherichia coli is perhaps best known as a bacterium t... Read More
A recent study by researchers at the University of Hawaii, Manoa, and the Oregon State University provides strong evidence that mitochondria share a common evolutionary ancestor with a lineage of marine bacteria known as SAR11, arguably the most abundant group of microorganisms on Earth.

Just listened to this weeks twiv, and the q dot dyes you mentioned are also used in electronics. There they are used as a ultra precise phosphor. In that application blue light from LEDs can be re-emitted as red, an... Read More
Introduction and uses of culture media for growing pathogenic bacteria and fungi
Scientists have managed to reverse type 1 diabetes (T1D) in experimental mice by giving the animals an oral course of harmless gut bacteria that had been engineered to secrete the whole proinsulin autoantigen (PINS) and the immunomodulatory human cytokine IL-10 (hIL10). An international team led... Read More
On the issue of antibiotic-resistant bacteria and animals, the first thing that comes to mind is livestock and other farm-based animals that are regularly fed antibiotics as growth promoters, but they are not the only source of resistance. Participants discuss studies showing that non-farm anim... Read More
Lots of organisms rely on symbiotic relationships, in which two species rely on each other for survival and one lives inside the other. But citrus mealybugs enjoy a triply symbiotic relationship unlike any we've ever seen...with one absolutely crucial exception.

A gene interferes with the caterpillar's molting hormone and influences the insect's desire to climb. A single gene in a caterpillar virus sends its victims running for the treetops, where they die and their bodies liquefy, sending an ooze of virus particles on their brothers and sisters below. ...

The NIH Human Microbiome Project, initiated in 2008, is a five-year endeavor at capacity building and creating a community resource to support this emerging field. As a part of developing community resources, the HMP is announcing: 1) key findings on a very large study of the microbiomes of heal... Read More
In a significant discovery that can be a major breakthrough in biotechnology, Indian mycologists have discovered fungi spores, considered as being able to withstand a temperature of 100-115 degrees celsius. Spores are reproductive cells capable of developing into a new individual without fusion... Read More
Vincent Racaniello accepts the Peter Wildy Prize for Microbiology Education, awarded annually by the Society for General Microbiology for an outstanding contribution to microbiology education. Filmed at the Dublin Convention Centre in Dublin, Ireland. Read More
An outbreak of E. coli infection was detected in Germany about two weeks ago. Health authorities say that over 1500 people have become infected and 17 have died so far. Cases of E. coli infection have been reported in several other European countries, including the UK, the Netherlands, Sweden, D... Read More
It’s an accepted concept by now that taking antibiotics in order to quell an infection disrupts the personal microbiome, the population of microorganisms that we all carry around in our guts, and which vastly outnumbers the cells that make up our bodies. That recognition supports our understandi... Read More
