Human vision is very advanced.  While a human child can look at a cartoon picture of a chicken and know that's a chicken, computers cannot.   We can also recognize cars, people, trees and lampposts instantaneously on a busy street without much thought and decide what to do.

That's an enormous number of computations and just one reason that coming up with a computer-driven system that can mimic the human brain in visually recognizing objects has been difficult.  Eugenio Culurciello of Yale's School of Engineering&Applied Science has developed a machine dubbed Neuflow, which is 'based' on the human visual system and operates much more quickly and efficiently than predecessors, coming closer to the mammalian visual system.

Premature ovarian failure (POF) is when a woman's ovaries stop working before she is 40.  Missed periods are usually the first sign of POF. Later symptoms may be similar to those of natural menopause. 

Most women with POF cannot get pregnant naturally. Fertility treatments help a few women; others use donor eggs to have children. There is no treatment that will restore normal ovarian function, though many health care providers suggest taking hormones until age 50.   According to the International Premature Ovarian Failure Association, between 1 and 4% of women suffer from POF – equivalent to between 250,000 and 1 million women in the USA alone.

There was a time a few years ago when the music industry was in the doldrums.   They blamed MP3 piracy, though it made no sense unless you were the kind of person who believes 'jobs saved or created' is also a valid metric for beneficial impact of government stimulus plans - basically, claiming that every pirated piece of music was a lost sale was unrealistically hopeful.   Most pirates may download something, but they weren't going to buy it anyway.

Yet capitalism began to reshape the music industry even when they couldn't figure out how themselves.  iTunes made it elegant for people to buy songs, and so they did, and now capitalism is at work in the music itself.
