Scientists have taken a major step towards creating an aircraft of the future, one powered by an ion drive rather than using moving parts and fuel like conventional aircraft.

In a paper published today in Nature, a team led by Steven Barrett from the Massachusetts Institute of Technology (MIT) described how they created a so-called electroaerodynamic-powered plane, one that uses solid-state propulsion, meaning no propellers or jet engines with expendable fuel.

“The future of flight shouldn’t be things with propellers and turbines,” Barrett says in the video below. “[It] should be more like what you see in Star Trek, with a kind of blue glow and something that silently glides through the air.”

Archaeologists just pried another secret of our past from the clutches of the earth, welcoming a new human species to our growing family tree.

This discovery began with an ancient foot, or what was left of one. A foot bone, called the third metatarsal, was found in the Callao Cave on the Philippine island of Luzon back in 2007.

The oldest known Homo sapiens remains, found nearby on Palawan Island, were dated to 30,000 to 40,000 years ago. But this mysterious foot is older, dated to 67,000 years ago.

European scientists looking for some of the oldest ice on the planet have homed in on a particular spot in Antarctica, where they will drill more than 1.5 miles (2.7 kilometers) below the surface of the ice.

Over the next five years, the “Beyond EPICA-Oldest Ice” mission will work at a remote location known as “Little Dome C” to start drilling for ice up to 1.5 million years old, the team announced today (April 9) at the meeting of the European Geosciences Union in Vienna, Austria.

“Ice cores are unique for geosciences because they are an archive of the paleo-atmosphere,” said Beyond EPICA’s coordinator Olaf Eisen of the Alfred Wegener Institute in Germany. [Antarctica: The Ice-Covered Bottom of the World (Photos)].
