A newly released series of dramatic time-lapse satellite images, available at Google's Timelapse Web site, shows just how quickly the world's landscapes have changed in the last 28 years.

The pictures, captured by the series of Landsat satellites and released in conjunction with the U.S. Geological Survey, NASA, and Time magazine, show several startling examples of how humans and natural processes have changed Earth from 1984 to 2012. You'll see the depressing decline of the Columbia Glacier in Alaska, the blossoming of Dubai's epic cityscape, and Las Vegas' urban explosion. There's also an alarming look at the deforestation occurring in the Brazilian Amazon forest. … Read more

It wasn't very long ago that for a developer to make a successful weather app, it had to have the most information possible. This meant developers would compete to pack tons of graphs, maps, diagrams, written forecasts -- and even forums where people could talk about weather -- into busy, confusing apps that tried to cover it all. But what you ended up with were long, listlike menus when the only information you probably wanted was what the weather might be like for the weekend.

Don't get me wrong, the feature-packed weather apps have their place, particularly when … Read more

One my biggest disappointments with Peter Jackson's "The Lord of the Rings" was its failure to include Tom Bombadil, the immortal woodsman who is immune to the One Ring.

The character has a small but intriguing part in J.R.R. Tolkien's trilogy, but of course there's no room for him in a blockbuster film. Not so, however, with this very cool Periodic Table of Middle Earth, which replaces elements with earthly characters from LOTR and "The Hobbit." … Read more

While we remain dubious about the legitimacy of using the word "invisible" when visible light isn't involved, that's what a team of engineers at Duke University have dubbed their creation. Seven years ago, they demonstrated their first "invisibility cloak" in a laboratory; now, thanks to 3D printing, the fabrication process is a lot more accessible.

The object -- which looks more like a Frisbee made of Swiss cheese than a wearable cape a la Harry Potter -- has a large hole in the center, with seemingly random holes in the disc. The size, shape, and placement of these holes have actually been determined using algorithms to disguise any object placed in the center hole from microwave beams aimed through the side of the disc, making it appear as though the object isn't there. … Read more

People like to claim that education is in crisis.

But it's surely no more in crisis than humanity itself, as it veers toward an unknown future while leering into screens for its solution.

However, Bartow High School in Florida garlanded itself in a particularly educative spirit this week by expelling a 16-year-old girl for putting a couple of chemicals into an 8-ounce water bottle and watching it go bang.

Should this tale not have exploded before your eyes this week, Kiera Wilmot wasn't merely expelled for this misdeed on school premises, she was also charged with felony possession … Read more

After more than a decade of work, Harvard University researchers have finally gotten the so-called "RoboBee" to take flight.

According to the scientists, the robot -- which is half the size of a paperclip and weighs less than a tenth of gram -- was able to hover for a few moments and then flew on a "preset route through the air."

"This is what I have been trying to do for literally the last 12 years," Robert J. Wood, principal investigator of the National Science Foundation-supported RoboBee project, said in a statement. "It's really only because of this lab's recent breakthroughs in manufacturing, materials, and design that we have even been able to try this. And it just worked, spectacularly well."… Read more

Using off-the-shelf 3D printing tools, silver nanoparticles, and cell culture, scientists at Princeton University have created a functional bionic ear that can detect radio frequencies far beyond the normal human range.

Living, 3D-printed tissue has been in the news a fair bit recently, but this is the first attempt at creating a fully functional organ with embedded electronics.

"In general, there are mechanical and thermal challenges with interfacing electronic materials with biological materials," said Michael McAlpine, an assistant professor of mechanical and aerospace engineering at Princeton and the lead researcher on the project. "Previously, researchers have suggested some strategies to tailor the electronics so that this merger is less awkward. That typically happens between a 2D sheet of electronics and a surface of the tissue. However, our work suggests a new approach -- to build and grow the biology up with the electronics synergistically and in a 3D interwoven format." … Read more

A new shirt being touted as "the better button-down" aims to make laundry as we know it a thing of the past. The entrepreneur behind it claims it never wrinkles and can be worn over and over, without being washed.

Marketing grad Mac Bishop, 24, says his shirt not only looks good, but is soft to the touch, resistant to wrinkling, and odor-free. To prove it, he wore one of the shirts for 100 days in a row without washing it.

"I've (run) 4 miles in this shirt, I've biked 5 miles in this shirt, I've thrown it on after a basketball game," Bishop told CBS News. "It airs out. It's the miracle fiber." … Read more

Robotic prostheses may have a way to go before they work exactly like human limbs, but researchers are making great strides. A team out of Georgia Tech is working on new technology that could give these robotic limbs something akin to a sense of touch.

Thanks to tactile-sensing material that covers the entire prosthesis and software that integrates the gathered data, this robotic arm can maneuver through clutter and distinguish between hard and soft objects as it grips, pushes, and pulls more intuitively.

"Up until now, the dominant strategies for robot manipulation have discouraged contact between the robot's … Read more
