Estonia is building an artificial intelligence powered robo-judge that will rule over a backlog of small court cases. It will be fed legal documents and analyse them before coming to a decision based on its pre-programmed algorithms and training. The'robot judge' would preside over disputes of less than €7,000 (£6,000/$8,000) and free up more time for humans to work on bigger cases. Any ruling would be legally binding but could be appealed to a human judge. The project and technology is still in its infancy and no set date has been announced for its roll-out, but the larger AI project it is part of will announce its results in May.

A range of robots capable of instantly making sushi at the touch of a button has been created by engineers. The machines do not require the years of training and hard-work needed for a human to become an accomplished sushi chef but can churn out the fishy delicacies relentlessly. Sushi-making firm AUTEC say the device can create 2,400 nigiri rice balls and 200 sushi rolls per hour. Monk Conveyors, based in the UK, manufactures the AUTEC robots.

Scientists may finally be close to understanding the mechanisms behind hallucination. Despite the dramatic perceptual changes that take place during a bout of hallucination, what exactly happens in the brain during these moments has long been a mystery. A new study on drugged mice has found that the phenomena associated with these episodes may be the result of reduced signaling in the visual cortex – not an increase, as was expected. The images revealed that even after taking the drug, the signals being sent were largely similar to those seen in its absence, indicating that the information itself does not change. 'You might expect visual hallucinations would result from neurons in the brain firing like crazy, or by mismatched signals,' says senior author Cris Niell, an associate professor and member of the Institute of Neuroscience at the University of Oregon.

UPS will leverage drones to deliver medical samples in the first FAA-backed and continuous commercial deployment of drone technology in America. According to UPS, an autonomous drone -- Matternet's M2 quadcopter -- will travel between locations at WakeMed's campus in Raleigh, North Carolina, flying distances of up to 12.8 miles along a fixed, pre-determined route. Currently, the samples are delivered on the ground via courier cars, says UPS, making the shipments susceptible to road traffic. The use of drones will both increase efficiency and lower costs, the company says. Samples are loaded onto the drone which then flies a predetermined route to a landing pad located within the hospital.

The laws will apply only in the EU for now, but it's possible these global companies will apply these laws elsewhere (Microsoft has already applied some EU regulations in other places.) Venezuela used to have an anti-government newspaper, but that was until the government made it impossible for them to get enough paper to print. So Venezuelans have turned to the voice-chat app Zello to spread news, get basic needs, and coordinate aid amid the country's political and economic crisis. Vice President Mike Pence said the US will be sending astronauts to the moon's south pole. Because there's tons of ice Pence says can be turned into life support and even rocket fuel.

Some artificial intelligences can perform tasks with superhuman ability, but just how clever are they overall? A competition called the Animal-AI Olympics will pit AIs against tests normally used to study animal intelligence. From April, AIs will battle it out in a virtual playground for a $10,000 prize pool. All the tasks involve retrieving a piece of food, but the skills needed to succeed vary in complexity.

As you learn your first language, your brain stores about 1.5 megabytes of information – just a little over the amount that would fill a floppy disc (that is what the picture for the save icon represents, if you are too young to remember them). "I thought it would be much more," says Frank Mollica at the University of Rochester in New York. When you hear a word that you know, your brain is accessing all kinds of information to help you make sense of it: the sounds that make up the word, the meanings it has, its context in a sentence, the tense of a verb, and more. Mollica and his colleagues used a branch of mathematics called information theory to figure out how many bits of data you would need to encode all of this to lean English. These are estimates, Mollica says, but they give us a ballpark idea that can quantify how much information language acquisition requires.

The EU has passed some of its most controversial rules in years, changes that could fundamentally alter how the internet works. We'll tell you what's true. You can form your own view. But opponents say it will have the accidental effect of banning all sorts of legitimate behaviour, punishing tech companies and maybe even "banning memes". What are the new rules?

Media reports are attempting to suggest that the strange "Momo" character has returned, despite it not actually existing. A flurry of reports over the last day or so have focused on suggestions that the character is appearing in "baby shark" videos in an attempt to terrify the children watching them, and convince them to engage in dangerous behaviour. While it may be true that there the image has appeared in one or some of those videos, they have probably been watched by very few people. What's more, the character does not actually exist – the model that the infamous picture shows was destroyed after it rotted – which means the stories actually only refer to somebody inserting the horrifying image into videos rather than anything supernatural. We'll tell you what's true.

Twitter users are being tricked into changing their birthdays – and finding themselves locked out of their account. A viral hoax flying around the site suggests that people change their birthday in their Twitter profile to 2007. If they do, they'll get access to new colour schemes on the site, it suggests. But there are no colour schemes to be unlocked. Instead, changing your birthday to that soon will just tell Twitter that you are under 13 years old, which in turn means you shouldn't be allowed on the site, and so will be kicked off.
