Repairing Voyager 2

Scientists at Nasa’s Jet Propulsion Laboratory have been working flat out over the last week repairing Voyager 2. The spacecraft is about 18 billion kilometres from Earth, so sending a command to it takes 17 hours.Alexa: save my life pleaseCould personal assistants like Alexa and Siri save your life? Research in the journal BMJ innovations has assessed how good the top four voice assistants are at giving sound medical advice – the results were mixed. Drones mesh it up in VietnamManaging a natural disaster like a flood is so difficult because often there are many unknowns - responders urgently need real time information on water levels in the swollen rivers for instance. Installing monitoring kit across long stretches of river is expensive and the sensors need replacing regularly. So how about deploying a squadron of drones to pick up the data instead? That has been happening in a trial in Vietnam. Dr Trung Duong, at Queen’s University Belfast tells us more.Purrfect robotsDo you need a robot that can work in the dark or a dangerous environment? Give it whiskers! After all, some bristles and a snout work well for the likes of dogs, mice and shrews. So researchers at Manchester Metropolitan University in the UK have spent hours watching whiskers in the wild and are now switching the twitching to robots in the lab. (Photo: Voyager spacecraft.

Supercomputers seeking solutions for Covid-19

Supercomputing power for Covid-19 solutionsThe world’s most powerful supercomputers are being used for urgent investigations into the Sars-Cov-2 virus. Professor Peter Coveney from the UCL Centre for Computational Science is part of this consortium of hundreds of scientists across the globe, and tells Gareth how this phenomenal amount of computer power is already trying to identify potential treatments and vaccine candidates for Covid-19. Hot and Cold CognitionGareth and Bill meet Professor Barbara Sahakian at Cambridge University to discuss her work on hot and cold cognition. Cold cognition is the mechanics of AI. Hot cognition is what humans do so well – being able to empathise. So if we are to take AI to the next stage eg. interactive care robots, it is the hot cognition that needs to be developed – the social and emotional side of AI.Digital Radio MondialeDRM is the sister standard to DAB. DAB has taken off in the UK and other developed countries, but it is DRM that is becoming more popular in the developing world – India, Pakistan, China are all using it. Recently Brazil added their support for DRM. The key with DRM is that it digitises everything so we don’t need a new infrastructure for it and it can even act as a backup in disasters when other forms of communication fail.

Privacy concerns over contact tracing apps

Contact tracing is an essential part of controlling the Coronavirus pandemic but how should this data be collected and shared? In previous pandemics the tech wasn’t advanced enough to be used widely, but now country by country new contact tracing apps are appearing. But what about our privacy, should our personal health information be so easily available and potentially be unsecure? Some of the tech giants have even developed new protocols to anonymise our data – but not all governments think this will work? Journalist Timandra Harkness tells us what types of apps are being used where and about the tech behind them.Making computers intuitiveIs it possible to make computers intuitive like us?

Could fitness trackers track COVID-19?

Could your smart fitness device detect if you were coming down with respiratory symptoms? A project collecting data from smart wearable devices to see if they can plot outbreaks of disease symptoms by reporting data in real time and giving it a geographical tag has been launched. This would allow local authorities to mount responses quickly before any virus spreads further.

In the depths of Lake Kivu – one of East Africa’s great lakes – there’s methane and they’re burning the methane to generate electricity. Kivu is one of Africa’s so-called ‘killer lakes’, because the gases it harbours could be deadly for the thousands who live on shore. Burning some of the gas could help make it safer.

Dispelling COVID-19 vaccine myths online

Thousands of people in the UK have now received the Pfizer COVID-19 vaccine and vaccinations have just started in Canada, yet despite promotion from the government, a recent survey shows many people are reluctant to have it. Part of this hesitation is due to misinformation and vaccine myths on social media. Anna-Sophie Harling Managing Director for Europe at NewsGuard– the trust tool web extension provider – talks about their special report on top COVID-19 vaccine myths online. Many of these myths have been circulating online for months so how can governments dispel these falsehoods and convince their populations to be vaccinated?
