Exome Sequencing Impact in Routine Care

Summary: They placed the pseudoscientific nonsense about selection for beneficial mutations into the context of positive selection for mutations, which are caused by the virus-driven degradation of messenger RNA. The mutations have been linked to all pathology. It’s as if all theorists want to become known as “biologically uninformed science idiots” via their associations with others who have touted claims about “beneficial mutations.” US Air Force Studying Impact of Exome Sequencing in Routine Care Who, among my fellow veterans, and…

Understanding cell type differentiation

The Wisdom of the Fly Crowds by Ed Yong Excerpt: “This is a landmark study of collective behaviour,” says Iain Couzin… “Never before has it been possible to unweave the intricate coding of social behaviour during collective decision-making.” When it comes to fruit flies, scientists…  can really start to understand the origins of collective behaviour—how genes in the fly’s neurons are activated, how those neurons process signals from the fly’s environment, and how they drive individual behaviours that, in turn,…

RNA-mediated cell type differentiation and behavior

Neuroscience Meeting Planner Now Available The Preliminary Program and Neuroscience Meeting Planner for Neuroscience 2014 are available. At the 2012 Meeting I learned that the microRNA/messenger RNA balance had emerged during the past decade to be the most likely regulator of all downstream effects on cell type differentiation. That inspired me to focus on what I knew about RNA-mediated events and put what we detailed about them in our 1996 Hormones and Behavior review into the context of a this…

New technique used in report of atomic-level ecological adaptations

Archaerhodopsin variants with enhanced voltage-sensitive fluorescence in mammalian and Caenorhabditis elegans neurons Directed evolution of a far-red fluorescent rhodopsin reported as: New technique uses a genetic tool and light to view and map neuronal circuits Excerpt 1): “This [directed evolution] experiment demonstrates how rapidly these remarkable bacterial proteins can evolve in response to new demands. But even more exciting is what they can do in neurons, as Viviana discovered,” says Arnold. Excerpt 2): After incorporating Archer1 into neurons that were…

Ecologically linked adapted ants and brains

Ants Swarm Like Brains Think A neuroscientist studies ant colonies to understand feedback in the brain. By Carrie Arnold April 24, 2014 Excerpt: “The behavior of each individual in the group is set by the rate at which it meets other ants and a set of basic rules. Its behavior alters that of its neighbors, which in turn affects the original ant, in a classic example of feedback. The result is astonishing, complex behavior.” My comment: The molecular mechanisms of…
