Listeria bacteria has been enlisted by researchers to selectively infect metastatic pancreatic cancer cells and deliver radioisotopes into them. The experimental treatment dramatically decreased the number of metastases (cancers that have spread to other parts of the body) in a mouse model of highly aggressive pancreatic cancer without harming healthy tissue. Mice livers are shown above. The saline control liver on the left presents a large number of metastases compared to the liver on the right which was subject to the radioactive Listeria treatment. ...

Biologists from James Cook University have discovered a new species of leaf-tailed gecko in Australia. The lizard is highly camouflaged against the granite boulders it lives on and grows to around 12 cm. It's been named the Cape Melville leaf-tailed gecko (Saltaurius eximius) after the region in northern Queensland where it was found.

A new study has found that most adults, everywhere in the world, are playing host to face mites. They live in our hair follicles, eat the oils we secrete, mate with each other near the surface of our skin, and sometimes venture out at night.

While it may sound counter-intuitive, new research suggests that selectively plucking hairs in very close proximity can stimulate some startlingly dense regrowth. The team behind the study, led by researchers at the University of Southern California, demonstrated that by carefully extracting 200 hairs, one-by-one, from the back of a mouse in a specific configuration and density, they could trigger the growth of around 1,200 new hairs in the area - a five-fold increase. The biological mechanism is shown below:



While it's very early days, the researchers say their findings, which were reported in the journal Cell, could pave the way for new treatments for balding, or alopecia. ...

What can we learn from chimps swinging their hips? In this Nature Video, the walking style of our primate cousins are investigated, and we see what they can teach us about our ambling ancestors.
