They might look like sinister aliens, but these bacteria-munching viruses could be the next weapon in the fight against infectious diseases.

The brain was long thought to be a kind of fortress, separated from the body by a virtually impenetrable barrier of specialized cells. Now, that view is beginning to shift, with increasing evidence that aliens can, and do, sneak in.

A news release issued by NASA’s Ames Research Center foretells the launch into space of a satellite inhabited by a bunch of nano-mariners who, left to their own devices, would no doubt rather curl up inside a bowel.

A tiny molecular machine used by bacteria to kill attacking viruses could change the way that scientists edit the DNA of plants, animals and fungi, revolutionizing genetic engineering. The protein, called Cas9, is quite simply a way to more accurately cut a piece of DNA.


Highly effective communities of bacteria in the world's deepest oceanic trench

An international research team announces the first scientific results from one of the most inaccessible places on Earth: the bottom of the Mariana Trench located nearly 11 kilometers below sea level in the western Pacific, which makes it the deepest site on Earth. Their analyses document that a highly active bacteria community exists in the sediment of the trench - even though the environment is under extreme pressure almost 1,100 times higher than at sea level.

One team of researchers has developed a unique way to measure caffeine levels. They’ve engineered Escherichia coli so that the bacteria’s growth depends on the concentration of the invigorating compound.

Naproxen, the over-the-counter anti-inflammatory drug, may also exhibit antiviral activity against influenza A virus, a team of French scientists has concluded in the journal Antimicrobial Agents and Chemotherapy.
