Pelicans have the life. They live by the water, fly over the ocean, and eat lots of fish. Among humans, only T.C. from Magnum P.I. comes close to matching them. And he's just a fictional character, played by Roger E. Mosley.

The Limits Of Simulation

The idea that the world might be living in a simulation — discussed in Marcelo's post this week — is brought to life with wit and power in Peter Weir's 1998 film The Truman Show. Young Truman, who has been raised inside a simulation — a reality TV show! — is free to explore his environment; he can move around and pursue his interests and interrogate and probe.

Health problems can put a strain on a marriage at any age. But as we get older, chronic illnesses can make it even tougher to keep the spark alive.

Scientists at the University of Chicago have uncovered one way couples can offset the stresses of illness and aging: more physical intimacy.

Couples who continue to be sexually active over the years report higher levels of satisfaction in their marriages, the sociologists reported last month.

There's never a good week for nuclear waste, but this week has been a particularly bad one. Officials at the Waste Isolation Pilot Plant in New Mexico have disclosed that 13 employees inhaled radioactive material after a major accident earlier this month.

While there's no risk to the public and the exposed workers did not need immediate medical treatment, the incident is shaping up to be a major setback for the nation's only dedicated nuclear waste dump.

Chickens That Lay Organic Eggs Eat Imported Food, And It's Pricey

Empty shelves where eggs should be at a Whole Foods Market in Washington, D.C. The store blames increased demand for organic eggs.
Dan Charles NPR

The other morning, I found myself staring at something strange and unfamiliar: empty grocery shelves with the word "eggs" above them. The store, a Whole Foods Market in Washington, D.C., blamed, in another sign, the dearth on "increased demand for organic eggs."

This scene is unfolding in grocery stores across the country. But Whole Foods' sign wasn't telling the whole truth. Demand for organic eggs is indeed increasing, but production is also down.

The reason behind that shortfall highlights an increasingly acute problem in the organic industry.

The sheer volume of food wasted in the U.S. each year should cause us some shame, given how many people are hungry both in our own backyard and abroad.

Now the U.S. Department of Agriculture has provided us with a way to understand our flagrant annual waste in terms of calories, too. It's pretty mind-boggling — 141 trillion calories down the drain, so to speak, or 1,249 calories per capita per day.

Neil DeGrasse Tyson Explains Why The Cosmos Shouldn't Make You Feel Small

Originally published on Fri February 28, 2014 9:45 am

Astrophysicist Neil deGrasse Tyson hosts a new TV series called Cosmos: A Space-Time Odyssey. It's an update of the influential 1980 PBS series Cosmos: A Personal Journey, hosted by Carl Sagan.
Patrick Eccelsine Fox

When it comes to "callings" we usually think of people who feel drawn to religious career paths. But if you ask Neil deGrasse Tyson how he became an astrophysicist he says: "I think the universe called me. I feel like I had no say in the matter."
