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


Originally published on Mon April 28, 2014 9:42 am



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.

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."

You're Old. You're a Rock. You Can See


I want to tell you the story of three rocks, starting with the oldest one ever found. That one is so small, if you put it in the palm of your hand you'd need a magnifying glass to spot it. It was found buried inside a hunk of sandstone near a sheep ranch in a remote part of Western Australia ...

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

Bacteria don't wear wristwatches. But they can take their sweet time hopping onto a potato chip.

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.
