Are We Alone? New Analysis Suggests Life Could Be Extremely Rare In the Universe| Statistics Crush Optimism in Search for Extraterrestrials | Search for Life, SETI | Space.com

Again with the mean scientists! Using a statistical method called Bayesian reasoning, they argue that the life here on Earth could be common, or it could be extremely rare — there’s no reason to prefer one conclusion over the other. With their new analysis, Spiegel and Turner say they have erased the one Drake factor…

Can a Playground Be Too Safe?

After observing children on playgrounds in Norway, England and Australia, Dr. Sandseter identified six categories of risky play: exploring heights, experiencing high speed, handling dangerous tools, being near dangerous elements (like water or fire), rough-and-tumble play (like wrestling), and wandering alone away from adult supervision. The most common is climbing heights. “Climbing equipment needs to…

The incredible floating fire ant

Creepy-cool description of emergent behavior in ant colonies — complex survival strategies that develop when relatively dumb individual insects interact with each other in surprisingly complex ways. Back in the lab, Mlot deposited colonies of 500 to 8,000 ants in large beakers. When gently swirled, each colony spontaneously formed a sphere. Mlot dropped these spheres…

The Blue Marble Shot: Our First Complete Photograph of Earth – Atlantic Mobile

The incredible story behind an image we’ve all seen hundreds of times, possibly the most reproduced photograph in history It’s an iconic image we have all seen hundreds of times, possibly thousands, and probably the most widely reproduced photograph in history. Because it’s in the public domain it has been used for everything from car…

Oh, that’s how you do a science fair project!

Jeez, kids these days. Not satisfied to merely participate in wildly cool science fairs and competitions sponsored by tech industry giants, now they’re teaching us what we did wrong on our own science fair projects, oh so many years ago. At least that’s what Kevin Temmer managed to do, all in a video which Pearson…

NASA prepares a Mercury probe for orbit

NASA’s Messenger probe is about 10 days away from parking in an elliptical orbit around Mercury, the innermost planet of our solar system. Messenger has been en route since 2004, making a crazy Spirograph-looking series of orbits around the sun, taking the craft past Venus, and past Mercury three times, and finally heading for orbit…
