Efforts are underway to drive down cost of using renewable energy.

Ancient continents were found under Antarctic ice, thanks to old data from a now-dead European satellite.

New analysis of data from the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) mission has revealed rocky zones called “cratons” in the Earth’s lithosphere, a zone between our planet’s crust and mantle. GOCE plunged into Earth’s atmosphere five years ago this month after the craft ran out of orbital-maneuvering fuel. While scientists were unable to predict exactly where GOCE would fall, no debris dropped into populated areas.

The new fuel cell could be a cheaper, more practical way to generate energy to heat homes and eventually run cars.

The VERITAS collaboration recently discovered a binary system with a very high-energy gamma-ray neutron star, the rarest and most extreme known object in the Universe.

A major factor holding back development of wearable biosensors for health monitoring is the lack of a lightweight, long-lasting power supply. Now scientists at the University of Massachusetts Amherst led by materials chemist Trisha L. Andrew report that they have developed a method for making a charge-storing system that is easily integrated into clothing for “embroidering a charge-storing pattern onto any garment.”

An inexpensive way to make products incorporating nanoparticles—such as high-performance energy devices or sophisticated diagnostic tests—has been developed by researchers.

It’s an unfortunate fact that a large percentage of people have some sort of trouble with their vision. Even if you don’t at the moment, every human eventually has enough trouble focusing both near and far that they’ll need glasses for one or the other as they age. Our pupils become more limited also, with young eyes able to expand and close from about 2mm to 8mm, while in seniors they hardly change size at all. Exposure to the wrong kinds of light can also lead to eye issues later in life.

Fortunately, there are a variety of high-tech solutions either available or planned that can help us delay, or workaround, or even prevent some of these problems. For many of us, the only time we think about getting new glasses or a different kind of contact lenses is when our prescription changes. But that old pair of glasses you’re wearing doesn’t include the latest high-tech advances, which might turn out to be important to you. Similarly, there is increasing competition in contact lenses as well. We’ll cover some of the most important advances below.

Watch Are We Getting Closer to Thorium Nuclear Fuel?, an Earth video from Seeker.

Increased attacks prove the importance of detecting threat behaviors early and monitoring network traffic, stopping cybercriminals in their tracks.
