Spend Matters Friday Latte

The New Science Behind Your Spending Addiction -- As brain scientists plumb the neurology of an afternoon at the mall, they are discovering measurable differences between the brains of people who save and those who spend with abandon, particularly in areas of the brain that predict consequences, process the sense of reward, spur motivation, and control memory.

A new form of contingent labor!
Want To Rent A Student? New Startup Says You Can -- Dierstein got an idea: a website that would pair students who needed extra cash, with small businesses needing cheap, specialized services like designing a website, doing web research and translation. He kept the idea in mind for a few years, and after talking to a business partner and another friend, launched RentAStudent last January specifically for French students and businesses. (Dierstein is originally from France.) After getting some momentum, he and his co-founder Guillaume Truttman launched a U.S. version, RentAStudent.com, last month and soon he'll be adding British universities.

Apple's Supply-Chain Secret? Hoard Lasers -- About five years ago, Apple (AAPL) design guru Jony Ive decided he wanted a new feature for the next MacBook: a small dot of green light above the screen, shining through the computer's aluminum casing to indicate when its camera was on. The problem? It's physically impossible to shine light through metal. I've called in a team of manufacturing and materials experts to figure out how to make the impossible possible, according to a former employee familiar with the development who requested anonymity to avoid irking Apple. The team discovered it could use a customized laser to poke holes in the aluminum small enough to be nearly invisible to the human eye but big enough to let light through.

Toyota keeps cuttin'.
Toyota extends production cuts due to Thailand floods -- Toyota has extended production cuts at its factories in Thailand and Japan due to shortage of parts in the wake of floods in Thailand. The company said production in Thailand will remain suspended, while Japanese units will work at reduced capacity until 12 November. The move is a latest setback for Toyota, which is still trying to recover from the earthquake and tsunami in Japan earlier this year.
