A horse trots along a dirt road in Turkey, encased by the Kurtsystems Car equine training system. What may look like a complex horse-drawn carriage is actually a high-tech way to automate the delicate process of training racehorses.

Solar Force Field
University Corporation for Atmospheric Research
The first computer-generated model of an entire sunspot—a magnetic anomaly on the surface of the sun—tracks the magnetic fields in the area, helping researchers figure out how the sun releases energy around the spots. At the dark center, or umbra, the field is so strong—about 1,000 times the solar average—that it blocks the solar gases that typically bubble to the surface.
Thinking of keeping a giant roach as a pet? Make sure it's infested with beneficial parasites first

What’s more disgusting than cockroaches? Mites that feed off cockroaches. Here, mites munch moist debris from around the breathing holes of a Madagascar hissing cockroach, an insect sometimes kept as a pet that, unfortunately, can trigger allergies.

Open Heart Surgery
Roger W. Winstead
This is a pig heart, procured from a slaughterhouse, beating on a heart-pumping machine called the Heart Cart. Because pig hearts share many anatomical similarities with humans', scientists often use them to test new medical devices and surgical procedures. Instead of operating on the entire, living hog, which costs about $2,500 for each experiment, the Heart Cart lets researchers work on just the hearts, dropping that cost to $25, by pumping them with a saline solution to make the heart valves move realistically.
Have you ever been taking pictures of an entire country from space and thought, "you know what, this is ok, but I want to photograph the entire hemisphere at once,"? Well, with Raytheon's new 16-megapixel infrared sensor, you can.
Or, more precisely, the government can. Designed to work as part of a satellite, the sensor uses 4,096 pixel rows and columns to produce what the company calls, "an 'unblinking eye' over an entire hemisphere."
The wind may be restless, but the fastest air-powered ground vehicle is surprisingly steady as it sails over the dusty ground. Called Greenbird, it was developed by English engineer Richard Jenkins and the U.K.'s largest private green electricity supplier, Ecotricity.
On March 26 in a dry lakebed in California, the craft broke the world land-speed record for wind-powered vehicles by more than 10 miles an hour, setting the new record at 126.2 mph.
Lemur IIa is a robot designed to autonomously inspect and maintain in-orbit space equipment such as the Orion crew exploration vehicle. Shown below on a model space telescope, the Lemur IIa was envisioned as an orbital Swiss Army knife. Each limb has four degrees of freedom and a "quick connect” feature, allowing astronauts to swap in different repair tools as needed.
After three years of piecing together hundreds of individual x-ray images, researchers were able to produce the first high-resolution picture of the five million atoms that make up a virus's protective shell. The yellow- and red-colored ribbons were highlighted to illustrate how four identical proteins join to form the building block of the blue-hued shell, or capsid, of the Ps V-F penicillin fungus-attacking virus.
