The Week In Numbers: The Most Expensive Experiment Ever, 700,000-Year-Old DNA, And More

Clean Curiosity

NASA engineers work on the Mars rover Curiosity in a clean room to prevent cross-planetary contamination.

Via Fairen et al.

233 degrees Fahrenheit: the temperature at which NASA sterilized the Viking landers before before they went to Mars (turns out that was probably unnecessary-if Earth microorganisms could survive on Mars, they’re probably already living there…)

€13 billion to €16 billion: the cost of the International Thermonuclear Experimental Reactor, the most expensive science experiment ever built (fusion energy, here we come!)

2022: the year the Italian Space Agency’s BepiColombo spacecraft will arrive at Mercury

15 minutes: the amount of brain-zapping required to make the people around you start to look hot, according to a new study

700,000 years: the age of the horse DNA that scientists recently decoded, shattering the record for the world’s oldest sequenced genome by nearly tenfold

$2,000: the amount this dad spent to sequence his daughter’s genome at home in order to pinpoint the cause of her rare syndrome

5 months: the age at which babies can recognize each other’s moods, according to an adorable new study

2 hours: the time it takes to build your own DIY waterzooka

10-15 μl: the amount of blood (just a drop!) that Japanese scientists used to clone a healthy, fertile mouse from a living donor

$500: the price to pre-order this cheaper, sportier Google Glass competitor

43: the number of times Jose Canseco has recently tweeted about science and made our heads explode

$200: the price of a new printed circuit board-based rotary motor that’s as strong as a gas-powered one, sans the emissions and noise
