Google to test 200 self-driving cars

General Motors. Toyota. Google?

One of the world's largest technology companies is getting into the car business — and hoping to turn drivers into passengers. The tech giant announced on its blog Tuesday that it plans to test about 200 of its own two-seat self-driving cars.

"We've been working toward the goal of vehicles that can shoulder the entire burden of driving," the company wrote. "They will take you where you want to go at the push of a button. And that's an important step toward improving road safety and transforming mobility for millions of people."

Charging portable electronics in 10 minutes

Researchers at the University of California, Riverside Bourns College of Engineering have developed a three-dimensional, silicon-decorated, cone-shaped carbon-nanotube cluster architecture for lithium ion battery anodes that could enable charging of portable electronics in 10 minutes, instead of hours

Lithium ion batteries are the rechargeable battery of choice for portable electronic devices and electric vehicles. But, they present problems. Batteries in electric vehicles are responsible for a significant portion of the vehicle mass. And the size of batteries in portable electronics limits the trend of down-sizing.

First 3-D pterosaur eggs found with their parents

Researchers have discovered the first three-dimensionally preserved pterosaur eggs in China. The eggs were found among dozens, if not hundreds, of pterosaur fossils, representing a new genus and species (Hamipterus tianshanensis). The discovery reveals that the pterosaurs -- flying reptiles with wingspans ranging from 25 cm to 12 m -- lived together in gregarious colonies.

Big Crash Theory: Moon May Be Child of Earth

The Moon might be the child of the Earth and another small planet, scientists say, claiming they have evidence of oxygen isotopes in Apollo moon samples. The team of German researchers studied several lunar meteorites and three basalt rock samples brought back by the crews of the Apollo 11, Apollo 12 and Apollo 16 missions some forty years ago, which they say contain evidence of a Mars-sized planet called Theia having crashed into Earth and created the moon.

Due to a new technique, the team detected a chemical difference between Earth and moon rocks, which according to their theory, proves that moon rocks contain traces of a body that clashed with the Earth.Most computer models esimate that between 70 percent and 90 percent of the moon is that mysterious Theia, so it should have a slightly different chemical makeup than Earth.

Computer scientists develop tool to make the Internet of Things safer

Computer scientists have developed a tool that allows hardware designers and system builders to test security -- a first for the field. There is a big push to create the so-called Internet of Things, where all devices are connected and communicate with one another. As a result, embedded systems -- small computer systems built around microcontrollers -- are becoming more common. But they remain vulnerable to security breaches. Some examples of devices that may be hackable: medical devices, cars, cell phones and smart grid technology.
