3D-printing breakthrough and other tech news you need to know

For the first time, researchers have successfully printed a robotic hand complete with bones, ligaments and tendons made of different types of polymers. The breakthrough was possible thanks to a new laser technique.

Researchers ETH Zurich, who conducted the work, believe it opens up new possibilities for the production of robotic structures that combine soft, elastic and rigid materials.

"Robots made of soft materials, such as the hand we developed, have advantages over conventional robots made of metal. Because they're soft, there is less risk of injury when they work with humans, and they are better suited to handling fragile goods," ETH Zurich robotics professor Robert Katzschmann explained.

The US administration has announced a proposal to split regulatory powers for private-sector space activities between the transportation and commerce departments.

The draft legislation would expand the Federal Aviation Administration (FAA) and the Department of Commerce's oversight of key areas. The FAA would see its remit expanded to cover areas including the licensing of crewed and uncrewed activities in space. Meanwhile, the commerce departments would have greater responsibility for various uncrewed spacecraft, including in-space servicing spacecraft.

The proposal is in response to a global treaty that requires countries to authorize and supervize the space activity of non-government bodies.

Researchers at MIT have developed a new process to create fuel from carbon dioxide. The new approach turns CO2 into formate, a solid fuel, that could be used to heat homes or in industry.

A new floating desalination machine, powered exclusively by waves, could help in the drive to create fresh water from salt water while avoiding the use of fossil fuels, the device's inventors say.

The European Space Agency has announced a new rocket, the Ariane 6, has passed a key rehearsal ahead of hopes for a debut flight next year. Ariane 6 is a joint venture between Airbus and Safran.
