and many have taken on the challenge of retrofitting energy hogs--to save money, to make cities more efficient,
and Glen Bull of the  Curry School of education at the University of Virginia, recently answered my questions about the project.
Bull: Producing and creating customizable manipulatives like base 10 rods, fraction cubes, geometric Tangram shapes all potentially support elementary students'mathematic proficiency and understanding in ways that the teacher controls.

A subspecies of Pyrenean ibex was cloned momentarily back to life. Credit: Joseph Wolf (1898), via Wikimedia) But returning to the merits of Mulligan's proposal, remember that resurrecting dead
such as the Asian gaur in 2001, but often with limited success. In 2009 Spanish biologists cloned the calf of an extinct subspecies of Pyrenean ibex from tissue samples preserved for that purpose,
but minutes after its birth the calf died of lung abnormalities (which have been cloned common among animals to date).
Moreover, all those cloning efforts crucially relied on the use of egg cells or surrogate mothers from living species closely related to the ones being brought back.
Meet the Maverick: the only fully legal flying carthe last time a flying car had shot a at making an impact was in 1956,
the Maverick Sport is powered officially a parachute. The Sport Pilot license required to fly it is much easier to obtain than a standard pilot's license.
For the first certified Maverick's vanity plate, FLY CAR seemed an appropriate choice. As for the hardware, it's a lithe, 900lb vehicle reminiscent of a dune buggy.
The Maverick Sport should be available for purchase in time for Airventure 2011 a yearly air show held in July.
the Maverick Sport has a unusual creation story. The mastermind of the project, a missionary named Steve Saint, created the Maverick not to indulge some kind of sci-fi whim,
but to solve practical transportation problems in the developing world. From CNN: What we're doing here at
'The Maverick flying car is just one piece of the puzzle for I-Tec. We've been working on this particular project for six years,
and sees the Maverick's potential uses as extremely diverse, from security to recreation to search and rescue.
So, for example, it would be possible to distinguish corn-fed cattle from Vermont from their cousins from Texas or Idaho.
