Salt is one of those dangerously tasty substances. We add the magical crystals of sodium chloride to almost everything that we cook or bake, and according to many public health experts, we add too much.
They want us to cut back, to lower our risk of heart attacks or strokes.
Yet when you really start looking for ways to do this, you run into a paradox and a scientific puzzle.
First, the paradox. Too much salt may kill us, but our bodies need some of it to survive.
Friday is the last day of a 5,125-year cycle in the Mayan calendar, sparking talk about the possible end of the world. About two years ago, a rumor began circulating on the Internet that the French village of Bugarach, population 200, would be the only place to survive this apocalypse.
But despite many news stories of people flocking to the village, less than two weeks before "doomsday," there was no one on the streets. Houses were shuttered against the cold.
It is Dec. 20, 2012 — and citizens of Earth are panicking, consumed by the idea that the world will end Friday, something they say was predicted by Mayan astronomers. Of course, most people are not panicking, and Maya expert David Stuart says no one should. The calendar, he says, has plenty of room to go.

Passengers can now use devices such as Kindles, iPads and Nooks while in flight, but not during takeoffs and landings. The FAA says it is studying the matter, but the chairman of the Federal Communications Commission and a U.S. senator say it's time to act.
When a human tragedy occurs on the scale of the Newtown shootings, clergy are invariably asked an ancient question: If God is all-knowing, all-powerful and benevolent, why does he allow such misfortunes?
There's even a word for reconciling this paradox: theodicy, or attempting to justify God's goodness despite the existence of evil and suffering.

Want to eat sustainably? Then eat bugs.
That's the word from the Dutch, who are doing their best to make a scientific case for the environmental benefits of insect proteins. Reduce greenhouse gases? Check. Produce more edible protein while using less land than more traditional livestock? Check.

Advocates of stricter gun control legislation are hoping that history will not repeat itself.
Last Friday's shootings at an elementary school in Newtown, Conn., have shaken the country, but it's unclear whether the intense feelings of the moment will translate into legislative action. Many times in the past, outrage over gun violence has dissipated before Congress has chosen to act.
