Alan Turing's 1950s tiger stripe theory proved

Researchers from King's College London have provided the first experimental evidence confirming a great British mathematician's theory of how biological patterns such as tiger stripes or leopard spots are formed.

A knockout resource for mouse genetics

An international consortium of researchers report today in Nature that they have knocked out almost 40 per cent of the genes in the mouse genome. The completed resource will power studies of gene activity in models of human ...

Mutant mouse reveals new wrinkle in genetic code

(PhysOrg.com) -- Call it a mystery with a stubby tail: an odd-looking mouse discovered through a U.S. government breeding program in the 1940s that had a short, kinky tail and an extra set of ribs in its neck – and nobody ...

Cell Phones Using Gesture Control (w/ Video)

Scientists discover gene that 'cancer-proofs' rodent's cells

(PhysOrg.com) -- Despite a 30-year lifespan that gives ample time for cells to grow cancerous, a small rodent species called a naked mole rat has never been found with tumors of any kind—and now biologists at the University ...

Meet the complete mouse -- whole mouse genome sequence published

Are you a man or a mouse? A new paper, published in this week's issue of PLoS Biology, explores exactly what distinguishes our genome from that of the lab mouse. In the first comprehensive comparison between the genes of ...

Expression of infrared fluorescence engineered in mammals

(PhysOrg.com) -- Researchers at the University of California, San Diego - led by 2008 Nobel-Prize winner Roger Tsien, PhD - have shown that bacterial proteins called phytochromes can be engineered into infrared-fluorescent ...

UCSF team closer to creating safe embryonic-like stem cells

A team of UCSF researchers has for the first time used tiny molecules called microRNAs to help turn adult mouse cells back to their embryonic state. These reprogrammed cells are pluripotent, meaning that, like embryonic stem ...
