Anatomically modern humans interbred with more archaic hominin forms even before they migrated out of Africa, a team of researchers has found. The discovery suggests genetic exchange with their more morphologically diverged neighbors was more widespread than previously thought and all humans today may carry genes from now-extinct Homo species.

Novel method for increasing antibiotic yields

Posted: 05 Sep 2011 01:09 PM PDT

A novel way of increasing the amounts of antibiotics produced by bacteria has been discovered that could markedly improve the yields of these important compounds in commercial production. It could also be valuable in helping to discover new compounds. With the ever-growing threat from antibiotic resistance, these tools will be very useful in ensuring that we have enough of these useful compounds in the future.

Stomach bacterium damages human DNA; Risk factor for gastric cancer

The stomach bacterium Helicobacter pylori is one of the biggest risk factors for the development of gastric cancer, the third most common cause of cancer-related deaths in the world. Molecular biologists in Switzerland have now identified a mechanism of H. pylori that damages the DNA of cells in the gastric mucosa and sets them up for malignant transformation.
