Across the globe, learning has been transformed over the last few months, often with the help of specialised tech. More and more educational technology, or EdTech for short, is entering the market. But how do governments, schools, and teachers know which tools and platforms to use? And how do countries with limited resources choose the best tech for their needs? Gareth is joined by Joysy John from NESTA and Susan Nicolai, from the Edtech Hub, to find out.Bot or not? With so many of us socialising and working online it becomes more important than ever to know whether we are talking to a real person or a computer-generated bot. A study from Carnegie Mellon University showed that 45.5% of users tweeting about coronavirus have bot characteristics. A new Mozilla-funded project called “Bot or Not” invites visitors to take part in a modern-day Turing test. One of the creators, Agnes Cameron, tells us about the project, bots online, and how to spot them. Lockdown views As many people are forced to stay at home we look at how some are using tech to keep looking out on the world. Many are flocking to online webcams to observe serene nature scenes or unusually empty streets in the tourist hot spots of the world. Jacqui Kenny has long used Google Street View to visit foreign places due to her fear of open spaces. She talks about her new photobook and how machine learning may help her find new images to capture.

In Spain, there are a total of nine COVID-19 tracing apps, but is this too many? Which type is preferable and does there need to be a more coordinated technology across Europe to track COVID-19? Digital Planet reporter Jennifer O’Mahony ask these questions and more on the programme.Ovarian cancer and AI In the final of our reports from the Cambridge Science Festival, Gareth and Bill meet Dr. Mireia Crispin Ortuzar. She researches AI that analyses radiographic images to help choose and track treatment for ovarian cancer. In the long-term, this type of technology could lead to more personalised medicine in response to cancer and, perhaps, in other fields of medicine as well.Robotic Ventilators At MIT, a team of scientists and engineers have developed a low-cost, open-source robotic hand that can operate manual ventilators. It could help fill the shortage of mechanical ventilators for Covid-19 patients across the globe, particularly in developing countries. Professor Daniela Rus tells Gareth how this new tech works.

Using anonymous mobile data, researchers tracked the movement of people from Wuhan to other regions of China and showed that it was possible to predict the spread of the virus throughout the country. Professor Nicholas Christakis, a co-author of the study, shares how it was done and what other countries could learn from it. Malawi Solar-Powered Radios Malawi could be highly affected by the coronavirus pandemic. In particular rural areas without access to electricity are in need of help. Brave Mhonie, the general manager for the charity Solar Aid in Malawi, tells Gareth about the plan to bring solar powered lights to remote clinics as well as radios to rural communities to spread information about COVID-19. Robot Zebra Fish In a laboratory in New York, scientists study zebra fish by having them interact with their robot counterparts. Reporter Anand Jagatia went to Tandon School of Engineering to find out how this is done and how robo-fish might be helpful in the future. (Photo: Chinese New Year celebrations.
