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.
Waves crash over the Kulluk oil rig, which washed aground on Sitkalidak Island, Alaska. Officials say aircraft have not spotted any signs of a fuel leak from the rig, which reportedly does not contain crude oil.

The drilling rig Kulluk, seen here in 2010, is specially built to work in the Arctic Ocean. Its round shape deflects ice floating in the water.

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.
Scientists at the Large Hadron Collider announced the discovery of the Higgs boson on July 4, the long-sought building block of the universe. This image shows a computer-simulation of data from the collider.
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.
Here's a motley crew for you. Newsman Dan Rather, rapper Snoop Dogg - or is it Snoop Lion - actress Molly Ringwald, Public Radio host Ira Glass and President Obama. All right, what do they all have in common? They all hosted question and answer sessions on Reddit this year, a link sharing website that's become one of the most popular social media communities online. This month, the site reported more than three and a half billion page views.
It's unlikely 2013 will be the year that jet packs make it big, but the coming year could bring us a host of other new technology trends and products, such as 3-D printers for consumers, smarter smartphones and more connected devices like glasses and cars.
