Almost 2,500 women of child-bearing age in the United Kingdom are at risk of transmitting mitochondrial disease to their children, evidence of how many families could potentially be helped by new IVF techniques to it.

The paper adds data to emotional debates about new regulations.  

Mitochondrial diseases are caused by inherited mutations in the DNA contained in mitochondria - tiny structures present in every cell that generate energy. Mitochondrial diseases can be devastating and particularly affect tissues that have high energy demands - brain, muscle (including heart), liver and kidney.

90 percent of the American public consider themselves spiritual so why is there a belief that 'religious' people are less likely to accept science? Environmentalism is certainly akin to its own religion, as is alternative medicine, and they are also widely considered anti-science, yet all three groups consider themselves fans of science - just not some science they happen not to like.

Electric cars are fine for people who have another car as a back-up or who only make short trips or who are not afraid of a little charge rage in the office parking lot.

For everyone else, electric cars only work if they are heavily subsidized. 

To become mainstream, and not just toys for elites like a Tesla, batteries need to get battery or they need to be leased. Otherwise, they remain in the realm of well-connected CEOs who get gigantic government subsidies to set up shop - like Tesla. 

Cancer uses a little-understood element of cell signaling to hijack the communication process and spread, according to Rice University researchers.

A new computational study by researchers at the Rice-based Center for Theoretical Biological Physics shows how cancer cells take advantage of the system by which cells communicate with their neighbors as they pass messages to "be like me" or "be not like me."

Despite enormous progress in cancer therapy, many patients still relapse because their treatment addresses the symptoms of the disease rather than the cause, the so-called stem cells. Work in the group of Veronika Sexl at the University of Veterinary Medicine, Vienna has given a tantalizing clue to a solution. In the current issue of Blood, the scientists report that the cell-cycle kinase CDK6 is required for activation of the stem cells responsible for causing leukemia.

Paleontologists have discovered a new species of a long-necked dinosaur. 

Qijianglong (pronounced "CHI-jyang-lon") was about 45 feet long and lived about 160 million years ago in the Late Jurassic. The name means "dragon of Qijiang," for its discovery near Qijiang City, close to Chongqing, and the fossil site was found by construction workers in 2006. The dig eventually came upon a series of large neck vertebrae stretched out in the ground - with the head of the dinosaur was still attached.
