Chemical Cocktail Can Keep a Heart Viable 10 Days, Outside the Body 97

Posted by timothy on Saturday May 15, 2010 @12:32AM from the with-very-few-exceptions-not-a-worm dept.

nj_peeps writes "Harvard professor Hemant Thatte has developed a cocktail of 21 chemical compounds that he calls Somah, derived from the Sanskrit for 'ambrosia of rejuvenation.' Using Somah, Thatte and his team have accomplished some amazing feats with pig hearts. They can keep the organ viable for transplant up to 10 days after harvest — far longer than the four-hour limit seen in hospitals today. Not only that, but using low temperatures and Somah, they were able to take a pig heart that was removed post mortem and get it to beat 24 hours later in the lab."

Submission + - Airborne Laser Successfully Shoots Down Missile (dailymail.co.uk)

Submitted by kborer on Saturday February 20, 2010 @11:31AM

kborer writes: A prototype airborne laser system discussed here last August has completed a new milestone:

The U.S. have successfully taken out a ballistic missile with a high-powered laser beam mounted to a plane, it revealed yesterday. The U.S. Missile Defence Agency (MDA) announced the feat after the test overnight on Thursday in central California. The plane uses lasers to lock onto the missile and follow its trajectory and then brings it down with a single shot from its nose — all in a matter of seconds. It is the first successful test of a futuristic, directed energy weapon and realises what had previously just been a science fiction fantasy.

Nothing has objective or inherent value. Some muddy water on the side of the road seems worthless to those walking by but would be priceless to someone dying of thirst. The price of something changes based on the subjective values of everyone participating in the market.

That is why there is little math in economic science. People assign ordinal values to things (item 1 is more valuable to me than item 2), but not cardinal numbers (item 1 is worth X). The price of something is not an objective value, nor even an average subjective value, but merely a historical fact that specifies at what price something sold for in a specific exchange. Consider how shares of the same stock can sell at wildly different prices at essentially the same time.
