NASA tests crazytech flying saucer thruster, could reach Mars in days

Let's test it! They guy inside will be reduced to the consistency of peanut butter.

The future in space is robots. Not those ridiculous little Martian toys but 4-5 foot-tall robots with long striding ability to walk up and over large rocks, replete with all human sensory, including the big one, TOUCH, sent back home instantaneously, all movements controlled from here. Without the need for food, sleep, oxygen or gravity so their "muscles'' won't melt away en route or upon landing. Made much tougher than us for 100s of blast-off and landings. Any nation can build them to be shot out into space in differently-designed ships taking advantage of a non-human robot's need and abilities, not a human's.

And any human that gets jealous and wants to grow up to be a space robot, science will eventually be able to transform them into one. Then an entire population of 'em can live indefinitely on a real star trek, undergoing periodic on-board repairs that will allow them to live for millenia. THAT'S the ticket!

Global warming COULD SHRINK THE HUMAN RACE

Re: I'm not sure about this

Bulletin, healthy adult humans even today range in size from just under 4 feet to about double that. Their size doesn't depend on whether they got much more or much less sun or water due to their local climate. It does depend, tho, on the level of nutrition they receive while they're growing and whether their genes support potential growth beyond a certain height. Within two generations, humans in general can eat differently and therefore grow to different sizes than their parents and grandparents. And do! Just look around! The idea the entire species would permanently shrink would have to mean their larger sizes would not allow them to live beyond puberty, and the smaller size would. That wouldn't be due necessarily to climate change, as it could have been over a period of many centuries with horses, but would require some kind of mass death of all prepubescents above a certain height. There would necessitate a bizarre change in the environment that would benefit a smaller size. Climate change could not account for that. So the implication in this POORLY written article, by someone who really has little clue to how evolution works, that rising or falling temps would necessarily kill off all tall prepubescants worldwide and benefit much smaller prepubescants, is too preposterous to figure out what kind of condtions could actually cause that.

If there's no protein around, a generation of 6 1/2 ft parents could see their kids grow to 5 ft and no more. Climate change does not imply any such condition. A world of exploding volcanoes would kill off most, and the rest would remain tall IF they had the protein to continue to eat. The conditions of what it would take to shrink human size universally is beyond the understanding of the "author" of this piece. I AM sure about this.

VERY BAD JOB, REGISTER.

Re: I'm not sure about this...

The tall Africans drink cow's blood. It's the protein that makes them tall, despite the temps. The entire article is junk. Climate change is real---400 billion tons of ice melt each day at the poles---but the not-so-bright idea the entire species could shrink due to climate change is really dumb, unless all protein disappeared, and the climate that would kill off all protein would kill us off too (we're protein!).
