The drive system will probably require some sort of exotic materials. But at least with the refined theory, the power requirements are not impossible. Perhaps impracticle, but not impossible.

Even only managing to make it to light speed (or even almost to light speed) would be very useful for our species.
While light speed still means years to even the closest star systems, it means that if it can be used safely in the Solar System, the other planets are just minutes to maybe an hour away. Commerce happens when you can get to Mars and back within an hour. The proposed 10 times light speed would make traveling to other stars viable as the closest star with seemingly viable life sustaining planets would be just a little over two years travel away.

Scientists Report First Success in Cloning Human Stem Cells:
"It’s been 17 years since Dolly the sheep was cloned from a mammary cell. And now scientists applied the same technique to make the first embryonic stem cell lines from human skin cells." See: http://news.yahoo.com/scientists-rep...160011071.html |

Kepler Telescope out of comission
http://www.bbc.co.uk/news/science-environment-22548886
hopefully they can get it fixed somehow or find a workaround, Kepler's been one of the more successful mission lately. |

Could a Drug Prevent Brain Aging?:
"Sharply reducing calorie intake, by as much as 40 percent, could slow aging in cells and may even prolong life span, studies have suggested. Now, researchers say they have found a way to mimic the beneficial effects of calorie restriction on the brain with a drug." "In the new study, researchers at the Massachusetts Institute of Technology focused on how calorie restriction affects brain cells. They showed that restricting the calorie intake of laboratory mice by 30 percent boosted levels of an enzyme in the brain, and delayed the loss of nerve cells that can accompany decline in brain function. The calorie-deprived mice also did better on memory tests, compared with their well-fed counterparts. Then, the researchers mimicked calorie restriction — they fed the mice a regular diet, but also gave them the enzyme-blocking drug. These mice had better functioning brain cells, and did better on cognitive tests, just as the mice that were fed a calorie-restricted diet."

COLD FUSION is BACK with 'anomalous heat' claim:
"Italian entrepreneur Andrea Rossi has surfaced again to restate his claim that his E-Cat low energy nuclear reaction kit puts out more energy than goes in. And so it is that the “cold fusion” debate will be re-ignited – this time with new voices in Rossi's corner. Giuseppe Levi and Evelyn Foschi (Bologna University, Italy); Torbjörn Hartman, Bo Höistad, Roland Pettersson and Lars Tegnér, all of Uppsala University in Sweden, and Hanno Essén of the Royal Institute of Technology in Stockholm, are claiming that the heat produced in the latest tests of Rossi's E-Cat rig is “one order of magnitude greater than conventional energy sources”.

Doctors save Ohio boy by 'printing' an airway tube:
"In a medical first, doctors used plastic particles and a 3-D laser printer to create an airway splint to save the life of a baby boy who used to stop breathing nearly every day. It's the latest advance from the booming field of regenerative medicine, making body parts in the lab." See: http://news.yahoo.com/doctors-save-o...125228957.html |

Neanderthals Went Extinct Because Of Their Large Eyes
Apparently, too much of their brain power was dedicated to vision and body control instead of managing social structures and whatnot. |
