Study hints that fruit flies have free will

A spark of free will may exist in even the tiny brain of the humble fruit fly, based on new findings that could shed light on the nature and evolution of free will in humans.

Future research delving further into free will could lead to more advanced robots, scientists added. The result, joked neurobiologist Björn Brembs from the Free University Berlin, could be "world robot domination."

"Seriously though," Brembs said that programming robots with aspects of free will "may lead to more realistic and probably even more efficient behavior, which could be decisive in truly autonomous robots needed for planetary exploration"...

Creepy-crawly robot to mend a broken heart

A device that sounds like a 21st-century version of a medicinal leech may soon be set loose inside the chests of heart patients. Resembling a robotic caterpillar, it will crawl across the surface of their beating heart, delivering treatment without the need for major surgery.

The device, called HeartLander, can be inserted using minimally invasive keyhole surgery. Once in place, it will attach itself to the heart and begin inching its way across the outside of the organ, injecting drugs or attaching medical devices. In tests on live pigs, the HeartLander has fitted pacemaker leads and injected dye into the heart. This video shows the latest prototype creeping over the surface of a beating model heart (2.1MB, mpg format).

The 20-millimetre-long robot has two suckers for feet, each pierced with 20 holes connected to a vacuum line, which hold it onto the outside of the heart. By moving its two body segments back and forth relative to one another it can crawl across the heart at up to 18 centimetres per minute. This back-and-forth movement is generated by pushing and pulling wires that run back to motors outside the patient's body. The robot is being developed by Cameron Riviere and colleagues at Carnegie Mellon University in Pittsburgh, Pennsylvania...
