Coyote + wolf = new breed of predator - Discovery.com- msnbc.com
"It is somewhat ironic that a trait that was created by humans may now prove to be beneficial for wolves as they deal with human-caused changes to their habitat." [See: http://sciencetrio.wordpress.com/2009/09/24/coywolves-expand-their-range/]
Scientist at Work - Eric Schadt - Enlisting Computers to Unravel the True Complexity of Disease - Biography - NYTimes.com
The problem is no surprise to Dr. Schadt. “It turns out that common diseases involve thousands of genes and proteins interacting on complex pathways,” he said.
In 2003, Dr. Schadt was first noticed as a co-author of a paper in Nature that articulated t
Anti-Aging Pill Targets Telomeres at Ends of Chromosomes: Scientific American
New York-based T.A. Sciences claims to be the only company in the world manufacturing a supplement in a pill form that has been lab tested and shown to stop telomeres from shortening, in hopes of halting the aging process. The product, TA-65, comes from e
ACTN3 Genotype Is Associated with Human Elite Athletic Performance
This suggests that the presence of α-actinin-3 has a beneficial effect on the function of skeletal muscle in generating forceful contractions at high velocity, and provides an evolutionary advantage because of increased sprint performance. There is also a

The Human Genre Project
The Human Genre Project is a collection of new writing in very short forms — short stories, flash fictions, reflections, poems — inspired by genes and genomics.
PLoS Genetics: Assessing the Impact of Transgenerational Epigenetic Variation on Complex Traits
In the context of evolutionary biology, the existence of an additional mechanism for the creation of heritable variation in complex traits could explain the faster than expected adaptation to environmental change that is often observed in natural populations [32]. There is indeed mounting evidence that epigenetic alterations (epimutations) can arise at high frequency, in response to environmental challenges or ‘genomic shocks’ [5],[33],[34]. Furthermore, our findings provide clear evidence that many epigenetic variants can be stably inherited over numerous generations in the absence of selection ([21]; this study). Such stability could thus provide populations with sufficient time to explore the adaptive landscape [35], and for neutral mutations to accumulate over the new epialleles, in a process that could ultimately lead to genetic assimilation [36].

Optogenetics uses a brain cell switch with two genetic parts. The first is a gene taken from an algae that activates the cell in the presence of blue light in order to turn towards the light and photosynthesis. In a neuron, that activation fires the cell. The second is from an archaeon, a salt-based extremophile, which responds to yellow light by pumping chlorideions. In a brain cell, that means not firing at all.
The Niche: Gene therapy combined with reprogramming makes disease-free cells
“The problem with gene therapy wasn’t with the gene but the fact that [the gene] wasn’t getting to the right cell.

The variations thus accumulated over successive generations, such that, over the course of three to four generations, the songs had evolved to sound more like the songs of wild-types than those of the isolated colony founders.
-
as it is well established that the vocal centres in the song bird brain are regenerated anew every mating season, it would be interesting to investigate whether the progressive changes in the pupils' songs are associated with changes in neurogenesis, cellular organization, or gene expression
