Scientists in Cambridge plan to set up a research centre to develop new ways to repair the Earth's climate.

Engineers in the EU's Centreline research project believe they can make a more efficient, less polluting airliner by improving on the current design layout. The innovation involves fitting an electrically powered fan at the rear of the aircraft. It’s cutting edge technology, and there is plenty of debate over how they can make the idea fly in the highly competitive world of aviation.

Amazon, which is racing to deliver packages faster, is turning to its employees with a proposition: Quit your job and we'll help you start a business delivering Amazon packages.

Underwater vehicles, diving robots, and detectors require their own energy supply to operate for long periods independent of ships. A new, inexpensive system for the direct electrochemical extraction of energy from seawater offers the advantage of also being able to handle short spikes in power demand, while maintaining longer term steady power. To do so, the system can autonomously switch between two modes of operation, as researchers report in the journal Angewandte Chemie.

The smallest pixels yet created—a million times smaller than those in smartphones, made by trapping particles of light under tiny rocks of gold—could be used for new types of large-scale flexible displays, big enough to cover entire buildings.

Instagram said Thursday it will now block additional hashtags that surface vaccine misinformation, but other hashtags and content promoted by anti-vaccination accounts are still thriving on the platform.

It's become a widespread hack for a lot of games. If you get stuck on a certain level or run out of lives, there are bundles or upgrades you can pay for to help you get through it.

Japan has started testing its fastest-ever bullet train -- capable of reaching 400 kilometers per hour (249 mph) -- as it continues to develop the revolutionary mode of travel.

Facebook is banning several prominent figures it regards as "dangerous individuals".

Scientists working to detect gravitational waves switched on their instruments for a third time at the beginning of April and immediately began to register events that could be interpreted as cosmic collisions. All five trigger events still need confirmation. The BBC's Roland Pease examines how telescopes worldwide are helping.
