Description
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 please
Could 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 Vietnam
Managing 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 robots
Do 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.
