Major psychiatric misdirections often share this intimidating mixture of a medical mistake lashed to a trendy idea. Any challenge to such a misdirection must confront simultaneously the professional authority of the proponents and the political power of fashionable convictions. Such challenges are not for the fainthearted or inexperienced.
Until Fred Gage came along, brain scientists accepted as a matter of faith that the neurons, or brain cells, you were born with were all the brain cells you would ever have. Then, two years ago, this 49-year-old neurobiologist at the Salk Institute for Biological Studies in La Jolla, Calif., showed in a groundbreaking experiment that neurons are constantly being born, particularly in the learning and memory centers. Gage's discovery forced scientists to rethink some of their most basic ideas about how the brain works. Even more exciting was the fact that the source of these new cells was neural-stem cells, master cells with the ability to morph into any type of brain cell, depending on the chemical signals they receive as they grow. Early studies hint that they may even belong to a more primitive population of stem cells that can form anything from skin to blood to liver.

If my grandchildren ever ask me where I was when I realised the internet was over – they won't, of course, because they'll be too busy playing with the teleportation console – I'll be able to be quite specific: I was in a Mexican restaurant opposite a cemetery in Austin, Texas, halfway through eating a taco. It was the end of day two of South by Southwest Interactive, the world's highest-profile gathering of geeks and the venture capitalists who love them, and I'd been pursuing a policy of asking those I met, perhaps a little too aggressively, what it was exactly that they did.
The Internet is like freakin' Kryptonite for hypochondriacs, right? It seems like very time you hit that Google Search button or refresh your email, you're just asking to stumble upon an ad, news story, or website that plays on your deepest fears about your health. And as someone who is definitely something of a hypochondriac herself, I would never want to instill unnecessary fear in others, but I definitely believe there's some truth to one web "rumor": That chemicals in some cosmetics promote breast cancer . There's a lot of confusion over what exactly in deodorant and other cosmetics might be linked to breast cancer, but one thing's for sure: Parabens (chemicals like methylparaben, ethylparaben, propylparaben, butylparaben, isopropylparaben, and isobutylparaben) are hormone disruptors (they mimic estrogen in the body) used in lots of different kinds of makeup, moisturizers, and hair care and shaving products.
First CO2 gas flow estimate from a submarine volcano:
An active region on the sun that unleashed a powerful solar flare on March 4 does not appear to be quieting down, and may have more surprises in store over the coming week, scientists say. An X1.1-class solar flare erupted from the sun at 11:13 p.m. EST on March 4 (0413 GMT March 5). X-class flares are the most powerful type of solar storm, with M-class eruptions considered to be mid-range, and C-class flares being the weakest.

There's no gentle way to put it: People who give in to racism and prejudice may simply be dumb, according to a new study that is bound to stir public controversy. The research finds that children with low intelligence are more likely to hold prejudiced attitudes as adults. These findings point to a vicious cycle, according to lead researcher Gordon Hodson , a psychologist at Brock University in Ontario.
This month, researchers are inaugurating the Event Horizon Telescope , a project that will try to take the first detailed pictures of the supermassive black hole at the center of our galaxy.
In Lewis Carroll's , the White Queen tells Alice that in her land, " memory works both ways." Not only can the Queen remember things from the past, but she also remembers "things that happened the week after next." Alice attempts to argue with the Queen, stating "I'm sure mine only works one way...I can't remember things before they happen."
The Large Hadron Collider (LHC), famously engaged in the quest for the Higgs boson, has turned up a heavier variant of a sub-atomic particle first discovered a quarter-century ago, scientists reported on Thursday.
