Three decades ago, some companies began adding a chemical called triclosan to their products and tried to convince consumers that their hand soap or toothpaste was better because it was “anti-bacterial.”
Now, scientists are finding traces of that compound in the environment, and it’s causing ... Read More
A mix of six different bacteria found naturally in the healthy gut system of mice and isolated from feces can succeed where antibiotics fail, and eradicate murine infection by highly contagious strains of the Gram-positive anaerobe Clostridium difficile, including the human epidemic 027/BI strai...

Bacteria can be pernicious, but they also keep your stomach digesting, turn cucumbers into beloved pickles, and can, apparently, also be used to make art. Of course, it all depends on how you want to define "art." But Zachary Copfer finds himself precisely where it intersects with science.
"I... Read More
Scientists have found a soil bacteria that not only resists the toxic effects of antibiotics -- it makes a meal out of them.
Many bacteria can protect themselves from antibiotics by modifying the compounds to make them harmless or by pumping the compounds out of their cells entirely. And othe... Read More

Every different life form on earth can probably be infected with at least one type of virus, if not many more. Most of these viruses have not yet been discovered: just over 2,000 viral species are recognized. While the majority of the known viruses infect bacteria and eukaryotes, there are only ... Read More
A simple blood test for Creutzfeldt-Jakob Disease and Mad Cow disease is a step closer, following a breakthrough by medical researchers at the University of Melbourne.
Using newly available genetic sequencing scientists discovered cells infected with prions (the infectious agent responsible f... Read More
Analytical Chemistry Researchers have created a spinning disk that can quickly tell--within 30 minutes--if food samples contain Salmonella. The most widely-used method to test for the pathogen involves growing out samples on petri dishes and can take days so this has potential to be much quicker... Read More
Any part of the human body that is open to the outside world it available for the colonisation of bacteria. While this blog has covered bacteria in the gut, the vagina and the throat, one area I’ve neglected to cover is the bacteria that get into the lungs. As the company I currently work for is...

A drug currently being used to treat ischemic strokes may prove to be a significant advance in the treatment of tuberculosis and ulcers. In a new research report appearing online in The FASEB Journal, a compound called ebselen effectively inhibits the thioredoxin reductase system in a wide varie... Read More
The world’s only twin astronauts will take center stage in an upcoming NASA experiment that will analyze whether or not identical siblings remain the same biologically if one travels to outer space while the other remains on Earth.
According to the US space agency, astronaut Scott Kelly will ... Read More
Poor Larry isn't looking too good. He's pale and clammy and he's been projectile vomiting over and over again while his carers just stand by and watch.
Yet their lack of concern for Larry is made up for by their intense interest in how far splashes of his vomit can fly, and how effectively th... Read More

Do you eat bread? Or drink beer? If so you've probably consumed yeast products from the National Collection of Yeast Cultures.
Yeasts are one of the earliest, if not the earliest, biological tools used by people. Brewers' yeast, Saccharomyces cerivisae, features widely in products we consume... Read More
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
