HELLO FROM EARTH - celebrate the International Year of Astronomy

COSMOS magazine, thought it would be a cool way to celebrate National Science Week in Australia - and the International Year of Astronomy - by sending a message to a potentially habitable planet outside the Solar System.

HELLO FROM EARTH is collecting messages that will be transmitted to Gliese 581d, a planet outside our Solar System which may support life.





Will we get an answer? No-one really knows. So why not send a message and find out? (since it will take 20years to get there dont expect a reply untill 2049)

Why We Get Fat

This is a great lecture by Gary Taubes an American science writer. The movie is 72 minutes long but well worth it!

Message:

-Great video on diet in general

-An interesting point in the video: Eating less doesn't work with weight loss, neither does exercising more.

-Here are some good quotes form the lecture:

"Insulin is the only hormone that tells your body to retain fat." - Gary Taubes

"Fat is mobilized [from fat tissue] when insulin secretion diminishes." -American Medical Association council on foods and nutrition 1974
