And the As NASA announced that they found evidence of flowing water on the surface of Mars,

we're launching a series of programs that will probe what it's going to take to send people to the red planet.

in the first place.

Try and be as relaxed as you can and just watch what happens to the vision, see how it feels.

We'll start very low.

So the risk of actually losing consciousness because you haven't got enough blood going to your brain is very, very low.

So it will just give you a feel of what it's like it's sort of the acceleration you might get or

First this week, the presence of four strains of intestinal bacteria could make the

difference between a child breathing easily and developing lifelong

asthma from the University of

of British Columbia, Brett Finlay. Really this is the first time we can

actually demonstrate certain microbes influence asthma. We did this in

children. We had 319 children from across Canada that were already being studied from birth to

age five. What we did is we collected the feces from these children at three months of age
