Discover Magazine - January 2003 Issue
Check out Discover magazine's January 2003 issue - it's a look back at the top 100 science stories of 2002; serving as a quick summary of what important science was done last year. Some of the highlights are: (66) Why space suits don't fit women - they were actually designed to fit men, that's why; (10) Gigahertz waves detected confirms Big Bang; (74) Babies are a lot smarter than we thought - and researchers still have to confirm that the majority of parents are given too much credit for having smarts; (75) The average colour of the universe turns out to be a pinkish beige - this after the colours of the stars from 200,000 galaxies were averaged; (3) The world's population growth is slowing down - the biggest reason? Women don't go for having kids as they did before. For example: roughly 40% of Brazilian women of reproductive age are now sterilized; (47) Last year, the US Congress voted to suspend animal rights for rats, mice and birds - this year, they're working on the researchers; (55) Stephen Wolfram and his book: A New Kind of Science; (34) Ice Ages may be brought on by the solar system passing through regions of the galaxy rife with supernovas; (2) Physicists found out that neutrinos are not massless after all; (7) Two mathematicians have provided a 13-line test for prime numbers - there goes cryptography and every secure transmission on the internet; (38) Quaoar discovered - located beyond Pluto, this 800-miles diameter minor planet is the largest found in our solar system; (42) Two physicists have figured out how to communicate beyong the speed of light - huh? (6) NASA discovers water at Mars south pole; (20) The US' EPA agrees that global warming is actually happening - Bush dismisses it as work of "the bureaucracy;" (65) Did Heisenberg try to build the A-bomb for Hitler? (16) Astrophyscists have proposed that Black Holes have no surface; (4) Researchers at CERN managed to "bottle" some antimatter. Check out the site for more!
The first chef
First came fire ... and then, as the camera shifts to the soon to be late-village idiot, you're left wondering -- just what was going through that mind -- and food is put on the fire, for the first time, and cooking is accidentally discovered by humanity. The first chef is ridiculed by grunts, then the local thug tries a sample of the burnt carcass, and soon, everybody gets queued at the McDonalds drive-thru. What happened? Richard Wrangham of Harvard believes there's more to cooking than evolutionary history would have you believe. Wrangham points out that there is no way homo sapiens could survive on just raw food. Raw food just doesn't give up calories as easily as cooked food -- and raw food makes the digestive system expend more energy to get at those calories. Cooking on the other hand breaks complex molecules down, allowing the digestive system to make easy work of them -- and cooking also softens food, allowing the body to get to the calories with less effort...
