Greatest Mysteries

LiveScience has a series running for last 15 days or so on greatest mysetries in science. the following 15 have so far been reported... I think - the biggest mysetry really is why does the universe exist or may be equivalent is why do I exist? I have an answer as well, " I exist to find out why do I exist". (Is it sufficiently round about?)

What Makes a Scientist?
How Does the Brain Work?
How Many Species Exist on Earth?
Does Alien Life Exist?
Who Are You?
What Causes Mass Extinctions?
How Did Human Culture Evolve?
What Causes Gravity?
How Did the Universe Begin?

Crows are closer to Humans in Problem solving

Crows have been found to be clever in the recent experiments reported. They are closer to analogical thinking, which is problem solving based on experience. The way humans also do, it seems.

Looks like the old Thirsty Crow fable is not a story, afterall.

We have something to Crow about. As well the Crows of the world!!
