Life on Mars? Now, while Curiosity takes pictures and lasers rocks, a new theory posits that Mars never had life, that the clay on Mars wasn't caused by water flow but rather by magma rich in water, which would have been too hot to support microbial life. Also, clay would have trapped more organic material if there WAS more organic material to collect. So... sorry to disappoint you. For now. (Los Angeles Times)
