The wind energy industry is dependent on something even more unpredictable than wind: Congress. Hidden in the turmoil over the "fiscal cliff" compromise was a tax credit for wind energy.
Uncertainty over the credit had lingered long before the last-minute political push, causing the industry to put off further long-term planning. So while the now-approved tax credit revives prospects for an industry facing tens of thousands of layoffs, don't expect to see many new turbines coming up soon.
People have been sharing food with strangers since ancient days, offering up the household's finest fare to mysterious travelers. Think Abraham and the three men of Mamre in the Bible and the folks who take in strangers after natural disasters like Hurricane Sandy. That deep tradition of generous hospitality has long been thought uniquely human.
If so, then bonobos, those gregarious African apes, may be more like us than we thought.
If a stranger attacks you inside your own home, the law has always permitted you to defend yourself. On the other hand, if an altercation breaks out in public, the law requires you to try to retreat. At least, that's what it used to do.
The millions of Americans who make New Year's resolutions to lose weight often have pictures in mind.
They're pictures that have been repeatedly supplied by the health and beauty magazines at supermarket checkout lines. They feature skinny models in bikinis, or toned guys with six-pack abs, and captions about how you could look like this by summer.
Some people go so far as to tape these pictures onto their refrigerators and cupboards. When they're tempted to reach for a cookie, they reason, the sight of that toned model might dissuade them from breaking their resolutions.
An oil drilling rig holding more than 150,000 gallons of diesel, lubricating oil, and hydraulic fluid has run aground near Kodiak Island in the Gulf of Alaska, after it was being towed during a storm. The crew was evacuated before the rig was incapacitated.
"The rig ran aground in a storm, with waves up to 35 feet and wind to 70 miles per hour," reports Jeff Brady, on NPR's Newscast. The Shell Oil rig is "about 250 miles south of Anchorage," Jeff says.
It's a year-end tradition to cobble together a list of the most important advances in science. But, truth be told, many ideas that change the world don't tend to spring from these flashy moments of discovery. Our view of nature — and our technology — often evolve from a sequence of more subtle advances.
Even so, chances are good that this year's list-makers will choose the discovery of the Higgs boson as the most important discovery of 2012.
Updated Jan. 1, 2013: I've added a postscript to this post. You can find it at the bottom of this page.
Look at yourself. Right now.
You are muscle,skin, bone, brain, blood, warmed by energy, and all of you, every cell, even the subsets of those cells, all trillions and trillions of them, are going to tire, waste and depart. In 10 years almost every bit of you will have been replaced by new bits.
As American make contributions to various charities at the end of the year, there is increasing evidence that politics is playing a role in their decisions. Research suggests that the way the charity presses certain ideological buttons predicts whether liberals or conservatives will pony up a donation.
