Significance of the discovery of anthrax toxin genes in a naturally occurring microbe other than Bacillus anthracis

Dr. Fraser discusses, for the first time, the significance of the discovery of anthrax toxin genes in a naturally occurring microbe other than Bacillus anthracis, the bacterium that causes anthrax.

Oxidants are responsible for sex in algae

Colonies of the multicellular green alga Volvox carteri exposed to temperatures of 111 degrees Fahrenheit (42.5 degrees Celsius) had twice the amount of free radicals, oxidants that can damage biological structures, as unheated colonies. High levels of oxidants within their cells activated the algae's sex-inducer gene, the researchers report.

Chemical agents extracted from Caribbean sea squirt may help find cancer treatments for certain deadly tumours

European Union funding is helping to find cancer treatments for certain deadly tumours using small marine animals. European researchers are using chemical agents extracted from a type of Caribbean sea squirt, named Ecteinascidia turbinata, to treat some tumours.

Brain builds early warning detection system by working out the odds on potentially harmful experiences

An experiment conducted by Dr Ben Seymour and colleagues at the Wellcome Department of Imaging Neuroscience, University College London, revealed that volunteers couldn’t recall the details of a specific test which had resulted in them receiving a mild electric shock.

Patients play computer games using only the signals from their brains

For the first time in humans, a team headed by researchers at Washington University in St. Louis has placed an electronic grid atop patients' brains to gather motor signals that enable patients to play a computer game using only the signals from their brains.

Gene that affects alcohol sensitivity

Since one of the basic risk factors for alcoholism is a tolerance to alcohol, researchers have long sought to understand the genetic differences among people that affect their sensitivity to alcohol. So far, scientists have met with little success.

Computational design used to engineer and construct a protein that could sense the nerve agent soman

Duke University Medical Center biochemists have used computational design to engineer and construct a protein that could sense the nerve agent soman. They said their achievement constitutes a proof-of principle that such engineered proteins can be made to detect nerve agents such as sarin and other toxic substances.
