In a healthy adult human body, most internal organs such as the brain, spleen, liver, and heart are devoid of microorganisms because the immune system keeps them in check. After human host death, however, the immune system falters and microorganisms proliferate throughout the body beginning in ... Read More

Hawaii Senate Bill 3124 would make Vibrio fischeri the official state microbe.
Here’s why, according to the bill:
Vibrio fischeri is deserving of being Hawaii’s official state microbe because of its broad reputation as among the best-studied beneficial microbes. These bacteria live in... Read More
I listened to the latest TWIP this morning. Dickson mentioned the herbicide atrazine but thought it was a fungicide. It is actually a herbicide in the photosynthesis inhibitor class. Another bit of trivia about ag chemicals is that old chemicals like ... Read More

E. coli engineered to produce the enzyme carbonic anhydrase, which converts carbon dioxide to bicarbonate and then to calcium carbonate,... Read More
A new study has revealed that bacteria use a form of communication similar to human language, but employing chemical signals instead of words. This language enables bacteria to thrive and researchers hope that by interpreting it they can develop new drugs to fight infections without bacteria dev... Read More

Norwegian researchers in Trondheim have achieved surprising results by exploiting nature's own ability to clean up after oil spills.
We all know that marine bacteria can assist in cleaning up after oil spills. What is surprising is that given the right kind of encouragement, they can be even mo... Read More
Nuevas guías de la Agencia de Protección Ambiental (USEPA) para las aguas recreacionales: éste es el tópico que discutiremos hoy con Grace Robiou, quien ha trabajado durante los últimos años buscando nuevos indicadores de riesgo que protejan mejor a los bañistas.

Tom talks with Vincent about viral central nervous system infections of global importance, Ebola virus, and running the fastest marathon dressed as a doctor.
Should we only consider bacteria as harmful to our bodies?
Bonnie Bassler is a molecular biologist who has made a stunning discovery: bacteria 'talk' to each other using chemical signals that enable them to act as a unit, mount attacks and coordinate defence. This phenomenon of bacterial com... Read More
