Bananas Could Make Cars Leaner, Greener

Researchers are going bananas in the quest to build cleaner, greener cars.

Brazilian scientists have developed a way of using fibers from bananas, pineapples and other plants to create plastic that is stronger and lighter than the petroleum-based stuff. So-called nanocellulose fibers rival Kevlar in strength but are renewable, and the researchers believe they could be widely used within a couple of years.

"The properties of these plastics are incredible," Alcides Leão, a researcher at Sao Paulo State University, said in a statement. "They are light, but very strong — 30 percent lighter and three to four times stronger."

That could reduce the weight of new vehicles, which would increase fuel economy. Several automakers are cutting weight in their campaigns to maximize mpg. Ford, for example, hopes to trim 250 to 750 pounds from its vehicles and is exploring nanotechnology to do so.

GOP's anti-immigrant stance could turn Texas into a blue state

Not today, to be sure, nor tomorrow. But to read the newly released census data on the Lone Star State is to understand that Texas, the linchpin of any Republican electoral college majority, is turning Latino and, unless the Republicans change their spots, Democratic.

Figures released last month by the Census Bureau show that during the past decade, Texas joined California as a majority-minority state: The percentage of whites in the Texas population declined from 52 percent in 2000 to 45 percent in 2010, while the percentage of Latinos rose from 32 percent to 38 percent. Nearly half of all Texans under 18 - 48 percent - are Latino.

What these numbers mean is simply that the Republicans have an existential problem. As America becomes increasingly multiracial, the Republicans have elected to become increasingly white.
