Oil execs get monster raises after a ‘very strong’ 2011

How big was my raise? Thiiiiiis big.

How big was your raise last year? John Watson, the CEO of Chevron, got a 52 percent bump in his compensation. That's a nice chunk of change for anyone, and in Watson's case, it brought his total yearly take up to about $25 million.

Which is nothing to complain about, unless Watson is comparing his raise to the raise of his rival giganto oil company. In that case, he might be feeling a little bit short-changed.

Scientists build energy-efficient computer out of crabs

Here is an amazing example of humans piggybacking on a natural phenomenon to create an incredibly clever system: crab-based computing.

A crab-based computer starts with swarms of crabs. These swarms include hundreds of thousands of crabs that, individually, run every which way but that, as a group, progress in one direction. Even more incredible -- when two swarms collide, they merge and start moving along the vector of their combined velocity (hellloooo, high school physics!).

So what does this have to do with computing? A team of researchers set up a system where crab behavior would provide the basic logic on which computers work. For instance, a computer might need to take inputs X and Y, and output the result “X or Y” -- a 1 if either X or Y is 1, and a 0 otherwise. Crabs can do that:

Millennials love cities because they provide the one thing their boomer parents couldn’t give them

Why is Gen Y migrating to the cities? Because millennials are craving the things they didn’t get in their suburban upbringings, like connectedness and adventure. Basically, they’re throwing off their cul-de-sac childhoods and seeking out authenticity.

Nathan Norris, urban infrastructure planner, lays it all out at the PlaceShakers blog:

Critical List: Emperor penguin population double previous estimates; a new fracking working group

A team using very high resolution satellite pictures counted twice as many emperor penguins in Antarctica than any previous study had.

President Obama formed a new working group in Washington to coordinate federal oversight of fracking.

Those earthquakes in Oklahoma and Arkansas could be caused not just by fracking wastewater disposal but by fracking itself.

Farm-in-a-truck teaches kids about sustainability

Compass Green is a mobile greenhouse built into a truck, which runs on vegetable oil (natch). Handsome hipsters Nick Runkle and Justin Cutter retooled the truck, which was already fitted with Plexiglas display panels, to turn it into a biofuel-powered educational farm on wheels.

Texas got a CRAZY amount of hail

That shit cray.

I know this looks like a firefighter standing in a crack in some rocks, but no, my friend: those are four-foot hail drifts in Amarillo, Texas. The reason they look so dirty is that this is basically the only precipitation the drought-stricken state has been getting lately -- Texas was covered in mostly dust, so now it's covered in mostly dusty ice. Which is not really an improvement in terms of things like agriculture, but it sure looks impressive.

Government spends $40 million mowing lawns of empty homes

The U.S. government owns 200,000 foreclosed homes. And to keep those empty homes looking spiffy for would-be buyers, the government has to keep up appearances -- including the appearance of the lawn. As a result, we taxpayers are forking over $40 million for lawn-mowing at these uninhabited houses.

Swedish fast food chain makes bank by becoming ‘Klimatsmart!’

Sweden's No. 1 burger chain got rid of its kids'-meal boxes and, contrary to expectations, sales of the meals rose. Apparently parents who are facing the prospect of their children scrabbling for survival on this wrecked cinder of a planet don’t like creating needless trash? At least in Sweden, anyway.
