Injecting modified bacteria related to those which cause tuberculosis could protect against the lung disease, US scientists say.
Experiments on mice showed the injections could completely eliminate tuberculosis bacteria in some cases

A bacterium found in soil is a showing promise as a way of delivering cancer drugs into tumours.
Spores of the Clostridium sporogenes bacterium can grow within tumours because there is no oxygen.
Scientists have been able to genetically engineer an enzyme into the bacteria to activate a cancer drug.
Experts said it would be some time before the potential benefits of the work – presented to the Society of Microbiology – were known.
Researchers have successfully injected cultured red blood cells (cRBCs) created from human hematopoietic stem cells (HSCs) into a human donor, according to study.
As the global need for blood continues to increase while the number of blood donors is decreasing, these study results provide hope that one day patients in need of a blood transfusion might become their own donors.
Fat cells in the skin have been identified as the source of chemicals needed to make hair grow, according to researchers in the US.
In Pic:Wayne Rooney famously had hair transplant surgery to combat a receding hairline
Experiments on mice, reported in the journal Cell, suggested hair stem cells were controlled by fat.
Injecting a type of fat cell stimulated hair growth in mice which otherwise struggled to grow hair.
