Space researchers have created the largest ever map of dark matter - that’s the invisible material making up 80 per cent of the universe.

UCL researchers used artificial intelligence to analyse images of 100 million galaxies, looking at their shape and spots of light made-up of 10 or so pixels - to see if they have been stretched.

The new map, a representation of all matter detected in the foreground of the observed galaxies, covers a quarter of the Southern Hemisphere’s sky.

The US Senate is pushing forward a sweeping package of laws to boost the country’s ability to compete with Chinese technology, as Congress takes an increasingly tough line with Beijing.

The bill includes authorisation for $190 billion to bolster the U.S. tech sector, plus $54 billion specifically to increase production of semiconductors, microchips and telecommunication equipment.

There’s apparently soon to be a new Twitter subscription service listed on smartphone app stores, but the social network is being cagey about what users will get for their money.

“Twitter Blue” could include an “undo” feature - which we’ve been waiting for - for tweets and possibly even a “reader mode” for getting through those long threads.

New global data is suggesting the rise in deaths associated with smoking, Reface AI is deploying artificial intelligence to turn street art murals and monuments to life, Britain’s first driverless vehicles have hit the road in Cambridge, and, take splat: a new free app called Bugs Matter can help map out how insect populations are being effected by pesticides and habitat destruction.
