Researchers have found a way to make artificial intelligence more energy efficient, reports Tech Explore.

Thanks to a mathematical breakthrough, AI applications like speech recognition, gesture recognition and ECG classification can become a hundred to a thousand times more energy efficient. 

According to Diagnostic Imaging, AI is capable of reading a chest X-ray as well as a radiology resident.  

Artificial intelligence (AI) algorithms can read chest X-rays as well as radiology residents, potentially fast-tracking interpretations, saving resources, and freeing up residents for other duties.

Artificial intelligence is helping scientists explore the surface of Mars, reports Jet Propulsion Lab.

Sometime between March 2010 and May 2012, a meteor streaked across the Martian sky and broke into pieces, slamming into the planet's surface. The resulting craters were relatively small - just 13 feet (4 meters) in diameter.
