Collective Dynamics Differentiates Functional Divergence in Protein Evolution

Collective Dynamics Differentiates Functional Divergence in Protein Evolution | Papers | Scoop.it
From www.ploscompbiol.org - March 30, 2012 2:58 PM

Proteins are remarkable machines of the living systems that show diverse biochemical functions. Biochemical diversity has grown over time via molecular evolution. In order to understand how diversity arose, it is fundamental to understand how the earliest proteins evolved and served as templates for the present diverse proteome. The one sequence - one structure - one function paradigm is being extended to a new view: an ensemble of different conformations in equilibrium can evolve new function and the analysis of inherent structural dynamics is crucial to give a more complete understanding of protein evolution.

Why Millennials Don't Want To Buy Stuff

Why Millennials Don't Want To Buy Stuff | Papers | Scoop.it
From www.fastcompany.com - July 17, 2012 2:04 PM

Compared to previous generations, Millennials seem to have some very different habits that have taken both established companies and small businesses by surprise. One of these is that Generation Y doesn't seem to enjoy purchasing things.


The Atlantic's article "Why Don't Young Americans Buy Cars?" mused recently about Millennials' tendency to not care about owning a vehicle. The subtitle: "Is this a generational shift, or just a lousy economy at work?"


What if it's not an "age thing" at all? What's really causing this strange new behavior (or rather, lack of behavior)? Generational segments have profound impacts on perception and behavior, but an "ownership shift" isn't isolated within the Millennial camp. A writer for USA Today shows that all ages are in on this trend, but instead of an age group, he blames the change on the cloud, the heavenly home our entertainment goes to when current media models die. As all forms of media make their journey into a digital, de-corporeal space, research shows that people are beginning to actually prefer this disconnected reality to owning a physical product.
