hybrids review

Plug-in hybrids differ from the current hybrid vehicles in that they can be recharged externally, from an ordinary power outlet.
In a conventional hybrid the battery is recharged from power generated by its wheels.
plug-in hybrids that run on lithium-ion batteries/last longer, more expensive/, instead of the nickel-metal hydride
In electric mode, the plug-in Prius gets 99.9 miles a gallon, according to a gauge on a screen in the middle of the dashboard. But it cannot go very far: the plug-in hybrid’s two batteries hold enough power for only seven miles, 4hour cahrge

new heart

Medicine's dream of growing new human hearts and other organs to repair or replace damaged ones received a significant boost Sunday when researchers at the University of Minnesota reported success in creating a beating rat heart in a laboratory.Experts not involved in the Minnesota work called it "a landmark achievement" and "a stunning" advance. But they and the Minnesota researchers cautioned that the dream, if it is ever realized, is still at least 10 years away.

If you're younger than 35, you'll probably live long enough to put David Levy's prediction to the test. Levy says that by 2050 we'll be creating robots so lifelike, so imbued with human-seeming intelligence and emotions, as to be nearly indistinguishable from real people. And we'll have sex with these robots. Some of us will even marry them. And it will all be good.
Levy lays out his vision of a Brave New Carnal World in Love and Sex With Robots: The Evolution of Human-Robot Relationships
