(AP) -- Restaurants around the world will soon use new DNA technology to assure patrons they are being served the genuine fish fillet or caviar they ordered, rather than inferior substitutes, an expert in genetic identification says.

Using stem cells, University of Florida researchers have connected muscle fibers to spinal cord tissue, which is essential to the brain's ability to control muscle movement. The junction also plays an important role in Lou Gehrig's disease, spinal cord injury and other life-threatening conditions. "With further development, the team's techniques could be used to test new drugs or other treatments for these conditions." Further down the line, the research could revolutionize how all drugs are tested.

“You are what you eat.” The old adage has for decades weighed on the minds of consumers who fret over responsible food choices. Yet what if it was literally true? What if material from our food actually made its way into the innermost control centers of our cells, taking charge of fundamental gene expression?

If the human brain – with 100 billion neurons forging trillions of connections – were not complicated enough, new research suggests that every neuron may have its very own genome.
Add McConnell's observation to the overwhelming evidence that epigenetic modifications influence traits such as obesity, or the suggestion that the sequences of many genes are subtlty altered after being transcribed, and you get the sense that organism are not content to stick with the genome they were born with.

Biology does seem to be a factor in the issue of suicide. From research, most people who attempted suicide were also found to have the gene called RGS2. 43% of the people who attempted suicide had this gene.

Now a small contingent of researchers, many of them evolutionary biologists who typically have nothing to do with linguistics, are looking at language from in front of their computers, using mathematical techniques imported from the study of DNA to wring scenarios of language evolution out of huge amounts of comparative speech data.

The results revealed which subjects were strongly and weakly associated. Chemistry was linked to almost no other science. Biology was linked to almost all of them. Health was tied more to business than to food. But why did fashion connect strongly to physics? And why was astronomy linked to genetics?

Evolution and the Emergent Self is an eloquent and evocative new synthesis that explores how the human species emerged from the cosmic dust. Lucidly presenting ideas about the rise of complexity in our genetic, neuronal, ecological, and ultimately cosmological settings, the author takes readers on a provocative tour of modern science’s quest to understand our place in nature and in our universe. Readers fascinated with “Big History” and drawn to examine big ideas will be challenged and enthralled by Raymond L. Neubauer’s ambitious narrative.

Virtually all organisms with complex cells—better known as eukaryotes—have at least two separate genomes. The main one sits in the central nucleus. There’s also a smaller one in tiny bean-shaped structures called mitochondria, little batteries that provide the cell with energy. Both sets of genes must work together. Neither functions properly without the other.

Scientists presented new research demonstrating the impact life experiences can have on genes and behavior. The studies examine how such environmental information can be transmitted from one generation to the next -- a phenomenon known as epigenetics. This new knowledge could ultimately improve understanding of brain plasticity, the cognitive benefits of motherhood, and how a parent's exposure to drugs, alcohol, and stress can alter brain development and behavior in their offspring.

Among the most fundamental challenges facing the scientists will be developing new computer models that more accurately predict the behavior of cells in the laboratory. Scientists can already program individual cells to complete certain tasks but scaling up to create a larger organism is trickier.
