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
Health officials have issued a warning for cantaloupes from a revered melon-producing area of the U.S. state of Colorado amid a bacteria outbreak blamed for four deaths in the state and New Mexico, troubling farmers who depend on sales of the fruit.
The warning from the Centers for Disease Co... Read More
Note the wheel-like appearance of some of the rotavirus particles. The observance of such particles gave the virus its name ('rota' being the Latin word meaning wheel). Bar = 100 nanometers. Rotaviruses are nonenveloped, double-shelled viruses, making the virus stable in the environment.

This sculpture made of purple and clear glass beads depicts bacteriophage Phi174, a virus that infects bacteria. It rests on a surface that portrays an adaptive landscape, a conceptual visualization. The ridges represent the gene combinations associated with the greatest fitness levels of the vi... Read More
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
The human microbiome consists of thousands of viral and microbial species which inhabit the human body and have co-evolved with us to protect against pathogens, regulate organ function and supply nutrients and other factors essential for health. When these members fall out of balance, it can le... Read More
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
This episode: Some bacteria have been discovered that construct multiple types of magnet in their cells!
El Dr. José Antonio Castillo, obtuvo su doctorado en la Universidad de Chile y luego realizo una estancia postdoctoral en el Departamento de Genética Molecular y Biología Celular, de la Universidad de Ch... 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
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. ...

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
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.
Microbiologist John McCutcheon... Read More
