A Non Visual Opsin Could Help Future Studies of the Brain and CNS

Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a light-sensitive opsin protein that plays a surprising and possibly critical role in neuron maturation and circuit formation.

The research is in Current Biology. (full access paywall)

> A schematic history of human civilization reflects a growing complexity of the collective behavior of human organizations. The internal structure of organizations changed from the large branching ratio hierarchies of ancient civilizations, through decreasing branching ratios of massive hierarchical bureaucracies, to hybrid systems where lateral connections appear to be more important than the hierarchy. As the importance of lateral interactions increases, the boundaries between subsystems become porous. The increasing collective complexity also is manifest in the increasing specialization and diversity of professions. Among the possible future organizational structures are fully networked systems where hierarchical structures are unimportant.

3 mistakes you make when you think about happiness:
Using examples from vacations to colonoscopies, Nobel laureate and founder of behavioral economics Daniel Kahneman reveals how our "experiencing selves" and our "remembering selves" perceive happiness differently. This new insight has profound implications for economics, public policy — and our own self-awareness.

3D Microscope Method to Look Inside Brains

Full article at http://neurosciencenews.com/3d-imaging-mouse-brain-1210.

A University of Utah team discovered a method for turning a small, $40 needle into a 3-D microscope capable of taking images up to 70 times smaller than the width of a human hair. This new method not only produces high-quality images comparable to expensive microscopes, but may be implanted into the brains of living mice for imaging at the cellular level.

The research is in Applied Physics Letters. (full open access)

Research: “An ultra-small three dimensional computational microscope” by Ganghun Kim and Rajesh Menon in Applied Physics Letters. doi:10.1063/1.4892881

Image: University of Utah engineers have developed a new microscopy method that uses a fine needle or cannula and an LED light to make 3-D images. They hope this new microscope technology, shown here, can be implanted into the brains of mice to show images of cells. Credit Ganghun Kim, University of Utah.

The Guardian: Britain will never be a champion of democracy while it sells arms to tyrants. http://google.com/newsstand/s/CBIwp72NwBo
A glance at the countries the UK's heavily subsidised weapon industry sells to – Russia, Israel, Saudi Arabia, Bahrain, Egypt – should rid you of any illusions about our foreign policy • Kaye Stearman: This year's DSEI arms fair needs to be the last
