Protein pathway competition regulates embryo development

Impact: Cell Biology    March 10, 2010
One thing I’ve noticed in following scientific developments for a long time is that when something unexpected is discovered it very often adds to the complexity. Here’s a recent case in point, first, I’ll let a piece of the announcement speak for itself, and then I’ll explain the context: Until now, scientists believed these pathways [...]

Iterating toward artificial life

Impact: Synthetic Biology    October 21, 2009
There’s more than one way to make a stew – but a primordial stew, the original mix of (whatever) materials from which life arose? This was a stew millions, if not hundreds of millions of years in the making. How can we recreate that evolutionary process within the ephemeral lifespan of a science laboratory? Then [...]

Beyond the genome: Mapping the epigenome

News: DNA Decoding    October 21, 2009
Given all the coverage, most people have heard about the ‘mapping of the human genome.’ It was a big project, taking many years (1990-2003) and costing about three billion dollars. Typically it was heralded as ‘one of the greatest scientific achievements of the century.’ It was that, although among those involved it was clearly a [...]

Can we stimulate repair of old muscles?

News: Extending Lifespan    October 10, 2009
Yes, we probably can stimulate more repair of muscle cells in older people. Berkeley — A study led by researchers at the University of California, Berkeley, has identified critical biochemical pathways linked to the aging of human muscle. By manipulating these pathways, the researchers were able to turn back the clock on old human muscle, [...]
