Scientists figure out how to unboil an egg

You can't unring a bell, but you can unboil an egg. Gregory Weiss, a professor of biochemistry at the University of California at Irvine, and his colleagues untangled the proteins of cooked egg whites to return a key protein to its previous uncooked state. A press release quotes Weiss:

“Yes, we have invented a way to unboil a hen egg,” said Gregory Weiss, UCI professor of chemistry and molecular biology & biochemistry. “In our paper, we describe a device for pulling apart tangled proteins and allowing them to refold. We start with egg whites boiled for 20 minutes at 90 degrees Celsius and return a key protein in the egg to working order.”

What's the point of this research? The ability to untangle proteins could lead to much cheaper cancer drugs

The first demonstration of self-propelled nanobots in a living animal

Researchers from the University of California have developed acid-fueled micro-machines capable of traveling and delivering cargo directly inside a living creature. It's a breakthrough that's expected to significantly advance the field of medical nano-robotics.

Scientists have developed drug-delivering micro-machines before, but these systems were only tested under in vitro conditions (i.e., cell cultures outside the body). But in this latest breakthrough, Wei Gao and colleagues have shown that artificial micromotors can travel inside a live mouse, deliver its cargo, and produce no toxic effects.

Robot snow plow in Japan scoops up snow in its "mouth" and leaves igloo bricks behind

Meet Yuki-taro, a self-guided, GPS and camera equipped robot snowplow that somehow manages to look as cute as Pokemon's Pikachu - this is Japan, after all! 

Snow? In Japan? Yes indeed, and not just on top of Mount Fuji. Some parts of northern Japan can receive a surprising amount of snow in wintertime, enough to block roads and isolate people living in mountain villages. Elderly people in particular are at risk in these areas, both from being shut-in and from trying to shovel all the snow. That's where "Yuki-taro, the friendly snowbot", comes in!

Neiman Marcus' digital mirror compares clothes side by side

posted by Larra Morris

If you've ever wanted to see yourself in a few different outfits before deciding on your next wardrobe, Neiman Marcus now lets you view them side by side. The retailer's Memory Mirror takes video and stills of what you try on for comparison, in addition to 360-degree views so you can see all the angles and items in different colors. As you might expect, snapshots from the digital mirror can be shared, so you can ask your Facebook friends if red really is the best choice. There's also an option to share the session with a salesperson so they can recommend new items next time.

Bioluminescent plankton illuminate the waters off Hong Kong

posted by Larra Morris

Noctiluca scintillans, a species of bioluminescent plankton, illuminated a stretch of coastline near Hong Kong yesterday in a stunning display that was captured in long exposure photos by photographer Kin Cheung. Unfortunately, as The Atlantic reports, the glowing bloom is caused by farm pollution. The plankton is also known as “Sea Sparkle.”

The subterranean theme park 390ft down in a Transylvanian salt mine

posted by Larra Morris

For hundreds of years, workers broke and hauled salt out of the Salina Turda mine in Romania. That stopped in the 20th century. Since 1992, the huge chambers left behind have been a tourist attraction, which became a full-fledged theme park in 2010. The features include a 65-foot-tall Ferris wheel, an amphitheater, bowling alleys, a miniature golf course, and a lake where you can ride a boat, all contained in the huge underground chambers.

Researcher develops jazz music-playing robots that can improvise with a human musician

posted by Larra Morris

Screen_Shot_2015-01-25_at_6.12.33_PM.png

Musician and researcher Mason Bretan plays jazz with a backup band of four robots in what at first glance appears to be a clever application of dancing robots and pre-recorded tracks, but is actually something much more remarkable. While two of the robots do indeed play prerecorded percussion, the other two are actually improvising along with Bretan’s playing. And all of them are swaying and dancing in response to the music. The largest robot, named Shimon, improvises on a marimba–a complex task that require the robot to pre-position its arms in anticipation of the next note. You can see Bretan and his robo-band in action in the six-minute improvisational piece, “What You Say.” Bretan developed the robots as part of his PhD research at the Georgia Institute of Technology.
