Watch: Beach-walking 'FlipperBot' inspired by baby turtles

While it might look like a giant robotic pet, scientists at the Georgia Institute of Technology have actually created the "FlipperBot" to generate new data on how organisms move.

The robot mimics the movements of sea turtle hatchlings struggling to reach the ocean. These little creatures need to rely on dexterity and flexibility in their wrists to get around without moving a lot of the surrounding sand.

"We are looking at different ways that robots can move about on sand," Daniel Goldman, an associate professor at the Georgia Institute of Technology, said in a statement. "We wanted to make a systematic study of what makes flippers useful or effective. We've learned that the flow of the materials plays a large role in the strategy that can be used by either animals or robots."… Read more

AP Twitter feed returns, minus many followers, after hacking

After spending the better part of a day offline -- following a hacking and fake tweet incident that caused a violent hiccup in the stock market -- the AP Twitter is back up and tweeting -- albeit, to far fewer followers.

The main Associated Press Twitter feed had almost 2 million followers Tuesday morning. That was before the Syrian Electronic Army apparently got hold of the account and tweeted the "breaking news" that a bomb had gone off in the White House, injuring President Obama. The hoax was almost instantaneously called out -- the formatting and channel used to send the tweet weren't consistent with AP standards. Also, it didn't go unnoticed that a live press conference happening at the time in the White House was uninterrupted by a bomb blast in the building.… Read more

Sea lion may be first nonhuman mammal to keep a beat

In the wild, sea lions are kept busy with hunting prey, caring for young, and swimming about in the great big ocean. In captivity, they have more time to devote to activities like sunning themselves, playing, and rocking out.

Ronan the California sea lion lives at the Long Marine Laboratory at the University of California in Santa Cruz. University researchers have studied Ronan's ability to keep the beat of musical tracks by nodding her head. She seems to particularly enjoy upbeat, jazzy disco numbers.

Ronan was first trained to bob her head to a simple metronome-like sound. Once she figured that out, she was able to find and keep the beat of more complex music all on her own. Previously, this ability has only been observed in parrots and humans.… Read more

View a 2,000-year-old scroll of the Ten Commandments online

Google is once again offering a glimpse into ancient history with online images of rare scrolls dating back more than 2,000 years.

Courtesy of Google, in collaboration with the Israel Antiquities Authority, the new Leon Levy Dead Sea Scrolls Digital Library is now home to detailed digitized photographs of thousands of biblical and non-biblical manuscripts. These ancient scrolls were discovered in remote caves near the Dead Sea between 1947 and 1956.

Among them, the scroll of the Ten Commandments may be one of the most fascinating. Dating back to sometime between 30 B.C. and 1 B.C., the … Read more

Cargo ship with metal sails would save 30 percent fuel

Can wind energy really power modern cargo ships? We've seen the idea of hybrid freighters before, but this concept from the University of Tokyo has a remarkable sail system.

A model of the UT Wind Challenger was recently shown off at the Sea Japan trade show in Tokyo. It would have giant telescoping sails that rise above the deck when wind conditions are good.

As seen in the vid below, University of Tokyo professor Kiyoshi Uzawa and collaborators believe this hybrid system could cut fuel consumption by cargo ships by about 30 percent. … Read more

AMD to acquire microserver vendor SeaMicro--a user of Intel chips

Advanced Micro Devices will acquire server vendor SeaMicro in an attempt to make a run at Intel in the microserver market.

AMD said it has signed a definitive agreement to acquire SeaMicro, a company that supplies energy-efficient microservers, for approximately $334 million.

To date, SeaMicro servers have been using Intel's Atom and Xeon processors. Future plans call for SeaMicro to build servers with AMD's Opteron chips.

"AMD plans to offer the first AMD Opteron processor-based solutions that combine AMD and SeaMicro technology in the second half of 2012. The company remains firmly committed to its traditional server … Read more

NASA mission calculates global ice melt and rising sea levels

From 2003 to 2010, NASA satellites systematically measured all of Earth's melting glacial ice--the results added up to 4.3 trillion tons of water and a global sea level rise of half an inch.

Put in perspective, that's enough ice to bury the entire U.S. 1.5-feet deep.

These calculations are detailed in a new study released today by a team of scientists at the University of Colorado. The scientists used satellite measurements from the NASA Gravity Recovery and Climate Experiment (GRACE), which launched in 2002 and focused on how melting ice from glaciers and ice caps … Read more

SeaMicro brawns up the microserver

Startup SeaMicro first packed lots of low-end Atom processors into servers to save power and space. Now Intel's beefy Xeon server chips are also getting the low-power treatment.

SeaMicro today announced its SM 10000-XE server, which it claims is the most energy-efficient Xeon server ever built. It consumes one half the power of a server with comparable computing muscle, takes one third of the space, and increases the available bandwidth twelve times, the company said.

The company is one of few companies that have taken a radical approach to server design by using arrays of less powerful processors, called &… Read more
