A protein called ARF, which acts as a fail-safe mechanism to protect against cancer, also prevents regeneration in mammals, a study published Aug. 6 in Cell Stem Cell suggests. ARF backs up Rb, an important anticancer protein, by limiting the ability of mature cells to divide and replicate. But researchers in California have discovered that blocking ARF and Rb allowed mature muscle cells taken from mice to proliferate, something the cells normally cannot do.The discovery is an important step in learning why mammals, including people, can’t regrow or replace lost limbs and organs the way animals such as salamanders and zebrafish can. Such work may one day lead to new treatments for injuries.

“The initial motivation for that was in fact cost,” Okuda explained. “Doing it purely as a graphic was considerably less expensive than buying electronic components. But very quickly we began to realize—as we figured out how these things would work and how someone would operate them, people would come to me and say, ‘What happens if I need to do this?’ Perhaps it was some action I hadn’t thought of, and we didn’t have a specific control for that. And I realized the proper answer to that was, ‘It’s in the software.’ All the things we needed could be software-definable.”
5. Andrew Morton writes worst book of 21st century – Awhile back, I probably wrote a blurb or two about Andrew Morton’s unauthorized biography of Tom Cruise, a book I’d never actually read but felt inclined to support due to its focus on his $cientology life. That was perhaps premature as Morton has just come out with a new biography on Angelina Jolie that is apparently so atrocious in its content and constant citing of unnamed sources that it led one critic to dub it the worst book of the century, so far. Ouch.
