Hooked On Light - Could Reveal The Biochemistry Of Addiction

mouse responding to light 

A newly created set of light-sensitive proteins grants scientists unprecedented control over the brain’s biochemistry, potentially shedding light on addiction and other complex neural processes. To demonstrate the potential of this novel molecular toolbox, researchers from Stanford University engineered mice to carry light-sensitive proteins in the brain’s reward center, which responds to drugs of abuse. Using pulses of light delivered directly to the brain, researchers were able to induce a druglike state, ultimately conditioning the mice to behave like drug-addicted animals.

Political Preferences: It Might Not Be What You Think

Political Preferences:  It Might Not Be What You Think 

Why does it seem many people begin with political preferences and then try to find reasons justifying their inclinations? Why is it so difficult to sway people who care deeply about politics no matter how compelling the facts or persuasive the prose? University of Nebraska-Lincoln research may help to answer these questions.
