The American space agency's InSight lander appears to have detected its first seismic event on Mars. The faint rumble was picked up by the probe's sensors on 6 April - the 128th Martian day, or sol, of the mission. It is the first seismic signal detected on the surface of a planetary body other than the Earth and its Moon. Scientists say the source for this "Marsquake" could either be movement in a crack inside the planet or the shaking from a meteorite impact. Nasa's InSight probe touched down on the Red Planet in November last year.
A man who almost died from meningitis has revealed how he began to look forward to having his limbs amputated. Mike Davies, 60, from Brighton, spent 70 days in intensive care with meningococcal meningitis and septicaemia. During this time, he said he knew his hands and feet were "dead" and he would recover better without them. Now he says he is in a positive place and "can even hold a pint of beer". With the help of prosthetic limbs, Mr Davies can drive a specially-adapted car and said he was living life to the full.
"But AI has no internal world and it has no need to create its desires or fears." So rather than letting AI take complete control, results seem to be far more fruitful when human artists work hand-in-hand with machines. Musician and University of Sussex lecturer Dr Alice Eldridge suggests that we should treat AI as "just another tool that we have designed, like the wheel, or the combustion engine". She has helped create a cello that uses a combination of acoustics, electrification and an adaptive algorithm that makes the instrument self-resonate; or essentially, play itself. "With a classical cello you have to bring the instrument alive with a bow; a feedback cello is already singing, your job as a performer is to shape the sound - it's more like a dance than'controlling' an instrument in the traditional way," she says.

The drone attack that caused chaos at Gatwick before Christmas was carried out by someone with knowledge of the airport's operational procedures, the airport has said. A Gatwick chief told BBC Panorama the drone's pilot "seemed to be able to see what was happening on the runway". Sussex Police told the programme the possibility an "insider" was involved was a "credible line" of inquiry. About 140,000 passengers were caught up in the disruption. The runway at the UK's second busiest airport was closed for 33 hours between 19 and 21 December last year - causing about 1,000 flights to be cancelled or delayed.
The number of recorded sexual offences involving online dating sites and apps has almost doubled in the last four years, police figures suggest. Offences where a dating site was mentioned in a police report increased from 156 in 2015, to 286 last year, according to figures from 23 of the 43 forces in England and Wales. The Online Dating Association said apps try to protect users from harm. But the National Police Chiefs' Council said firms had a duty to do more. The figures reveal that between 2015 and 2018 there were a total of 2,029 recorded offences - including sexual offences - where an online dating website or app was mentioned in a police report.
Is workplace surveillance about improving productivity or simply a way to control staff and weed out poor performers? Courtney Hagen Ford, 34, left her job working as a bank teller because she found the surveillance she was under was "dehumanising". Her employer logged her keystrokes and used software to monitor how many of the customers she helped went on to take out loans and fee-paying accounts. "The sales pressure was relentless," she recalls. She decided selling fast food would be better, but ironically, left the bank to do a doctorate in surveillance technology.
The makers of the official world snooker video game have been accused of a marketing failure after leaving the current world champion off the cover of their latest title Snooker 19. Images of Mark Selby, Ronnie O'Sullivan, Judd Trump and Neil Robertson were preferred to the 44-year-old Welshman Mark Williams. However, the current world number three has responded in good humour. Fans have questioned the decision to omit Williams's image, and his wife Joanne has accused World Snooker of "massive prejudice" and asked whether it is his age or because he is Welsh. The Twitter account for Snooker 19 explained: "There are 128 players in the game and only space for four on the cover. We were never going to be able to please everyone so we worked with World Snooker to make the tough decision."
