It's not every day that a new window on the birth of the universe is thrown open. It's not every day that human beings get the chance to leap into the void and have their conceptions of space and time stretched to the limits. It's not every day that we see the wildest dreams of scientists realized, written into the fabric of space and time and light.

Today appears to be one of those days.

St. Patrick's Day is my excuse to present you with the following illusion in green, courtesy of Akiyoshi Kitaoka, a psychology professor at Ritsumeikan University in Japan.

This image includes two spirals in different shades of green, one a yellowish light green and the other a darker turquoise green. Right?

Wrong.

How easy is it to spot a fake ID?

As an international armada of planes, ships and helicopters continues to comb the Indian Ocean for any sign of Malaysian Airlines flight 370, now missing for more than a week, Interpol confirms that two passengers aboard that flight were traveling on stolen passports.

Aviation experts say the incident highlights a major security gap at many airports: It is simply too easy to board a flight using someone else's photo ID.

Physicists, Generals And CEOs Agree: Ditch The PowerPoint

About six months ago, a group of physicists in the U.S. working on the Large Hadron Collider addressed a problem they've been having for a while: Whenever they had meetings, everyone stuck to the prepared slides and couldn't really answer questions that weren't immediately relevant to what was on the screen.

The point of the forum is to start discussions, so the physicists banned PowerPoint — from then on, they could only use a board and a marker.

Not-So-Objective Scientists Cling To Accepted Wisdom

RACHEL MARTIN, HOST:

Scientists are usually portrayed as highly rational seekers of the truth - and they are that. But they also have qualities that make them more similar to you and me than you might think. NPR's Joe Palca has a story that reveals that quite dramatically. Joe's been immersed in an NPR series called Joe's Big Idea, where he explores the minds and motivations of scientists and inventors. And from time to time, he drops by to share some of the interesting things he's learned. Hi, Joe.

JOE PALCA, BYLINE: Hi, Rachel.

Beware Of The Quick-Fix Mirage

Just because you can get your body or your mind in shape doesn't mean you will actually do the hard work necessary to succeed. Inertia is powerful thing.

An article last week in The New York Times reported that the scientific jury is still out on brain-fitness programs. It seems that playing computer games designed to work your powers of perception, memory and attention can lead to significant and lasting improvement in one's ability to play those very games. But the benefits don't transfer. You may perform the relevant tasks like a 20-year-old, but you'll still have the mind of a 60-year-old.

Why'd The Scientist Cross The Road? To Figure Out Why You're Laughing

Here's a joke: A man is sitting on the porch with his wife one night when, out of the blue he says, "I love you." His wife says, "Was that you? Or was that the beer talking?" The man says, "That was me — talking to the beer."

Maybe you laughed at that and maybe you didn't, but either way, cognitive neuroscientist Scott Weems wants to know whether you found it funny. In his new book HA! Weems explores the science "of when we laugh and why."

Rethinking The Five-Second Rule: With Carpet, There's No Rush

Many of us will happily eat a gummy bear or cookie after it falls on the floor, as long as we snatch it up quickly. Say, five seconds or less, right?

Well, science just gave us another excuse to continue this food-saving habit, especially when it comes to carpet-dusted snacks.

Biology students at the Aston University in Birmingham, U.K., measured how quickly two common bacteria hop aboard foods dropped on tiles, linoleum and carpet.
