>Touchless touchscreen
Cambridge University researchers have developed a "no-touch touchscreen".
The technology works by predicting where a user intends to touch the screen as they begin the hand movement towards the screen.
A combination of AI and sensors determine the user's intent in real time by tracking contextual information like the user's profile, environmental conditions and an eye-gaze tracker.
The "predictive touch" technology can be retrofitted to existing displays and could be used to prevent the spread of pathogens on touchscreens at supermarket check-outs, ATMs and ticket terminals at railway stations.

>Original drawing of Olympic rings
An Olympic flag design created by Pierre de Coubertin was sold for 185,000 euros on Sunday, the auction house in Cannes that organized the sale said.
The drawing is made on a white canvas measuring 21cm x 27.5cm, in graphite and opaque watercolor, and consists of an intertwining of five rings of different colors.
The five rings represented the five participating continents of the time.
Alexandre Debussy, associate director of Cannes Encheres, said that the design was sold to a Brazilian collector for that sum, adding that France's National Sport Museum made a bid that was not enough to secure its purchase.
Created in 1913 by Coubertin, the father of the modern Olympics, the design had been given to one of his supporters in Lausanne, and stayed in the same family until it was bought by the collector who put it up for auction on Sunday.

>UK to tackle obesity issue
The UK government will enforce a number of regulations on food retailers and advertisers to combat weight gain, as mounting evidence links obesity to increased risk of severe COVID-19 infection.
The new rules include a ban on "two-for-one" junk-food promotions, as well as restrictions on the airing times of television and online commercials for fatty and sugary products.
Large restaurants, cafes, and takeaways soon will be mandated to print calorie information on their menus.
Two in three Britons are overweight or obese, according to the UK Department of Health and Social Care, and the pandemic has instilled new urgency within the government to diffuse what it calls the "obesity time bomb".
"If we all do our bit, we can reduce our health risks and protect ourselves against coronavirus - as well as taking pressure off the NHS," UK Prime Minister Boris Johnson said on Monday.



>Concert coronavirus experiment
German scientists are planning to equip 4,000 pop music fans with tracking gadgets and bottles of fluorescent disinfectant to get a clearer picture of how coronavirus could be prevented from spreading at large indoor concerts.
The "coronavirus experiment" will be held at an indoor stadium in the city of Leipzig on Aug 22.
Participants, aged between 18 and 50, will wear matchstick-sized "contact tracer" devices on chains around their necks that transmit a signal at five-second intervals and collect data on each person's movements and proximity to other members of the audience.
Inside the venue, they will also be asked to disinfect their hands with a fluorescent hand-sanitizer - designed to not just add a layer of protection but allow scientists to scour the venue with UV lights after the concerts to identify surfaces where a transmission of the virus through smear infection is most likely to take place.
The project's organizers say the aim is to "identify a framework" for how larger cultural and sports events could be held "without posing a danger for the population".
