May 05, 2020 Chinese mobile data predicts Covid-19 Spread
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.

April 28, 2020 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 intuitive
Is it possible to make computers intuitive like us? That’s a question that Professor Mateja Jamnik from Cambridge University is trying to answer by building computational models that capture human informal reasoning – essentially trying to humanise computer thinking. Gareth Mitchell and Bill Thompson visited Professor Jamnik in Cambridge before the lockdown.
Tech to tackle locust storms update
Gareth speaks to Senior Locust Forecasting Officer Keith Cressman to find out if any of the tech that was being deployed to try and control the locust storms in the Horn of Arica and the Indian Subcontinent is working.
The programme is presented by Gareth Mitchell with expert commentary from Bill Thompson.

April 21, 2020 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. The study is called DETECT and one of those involved is Dr. Jennifer Radin an epidemiologist at Scripps Research Translational Institute in San Diego California and she joins us on the programme.
COVID-19 Cybercrime
Why are we more susceptible to cybercrime during lockdown? A new report just published by The Global Initiative against Transnational Organized Crime entitled “Cybercrime – Threats during the COVID-19 pandemic” is trying to answer that question. From attacks on hospitals, to a massive rise in the registration of websites with coronavirus, pandemic and COVID-19 in their addresses, the report looks at how our behaviour, our tech and the criminals, have changed in the last few months making cybercrime an even greater threat than before.
How safe are sex robots?
Sex robots are increasing in popularity. But as more people around the world bring these increasingly sophisticated androids into their homes, what new risks do they bring with them? As countries across the globe enforce strict lockdowns, many of us have felt the power of technology to counter loneliness and isolation, but how close should we let our tech get? And when technology is so taboo, do important discussions about safety ever see the light of day? Luckily, roboticists and regulators are beginning to grapple with some of these issues. Geoff Marsh has been finding out more…

April 14, 2020 Supercomputers seeking solutions for Covid-19
Supercomputing power for Covid-19 solutions
The 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 Cognition
Gareth 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 Mondiale
DRM 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.

As many schools around the world close their doors, more and more learning is shifting from the classroom to the home. 17 million households in twelve countries across sub-Saharan Africa are now benefitting from Ubongo – the TV, radio, online and mobile learning platform. Iman Lipumba of Ubongo explains how it works.
Culture in Quarantine; sacred music at Easter
Twenty musicians in the famous Tenebrae vocal ensemble have recorded an Easter recital for television, despite socially isolating all over the world. Quite a challenge for the singers, their conductor Nigel Short and the production company Livewire Pictures. Jan Younghusband BBC Music Head of Music TV Commissioning explains how it all happened.

Cyber criminals are exploiting the pandemic to send fraudulent emails and deploy all kinds of tools to steal our money, our contacts or our identities. Armen Najarian, the chief identity officer at email security firm Agari, updates us on the latest coronavirus driven cyber-attacks including scammers pretending they are emailing from the WHO or CDC.
Can the internet cope with the massive increase in demand?
Jane Coffin, SVP, Internet Growth from the Internet Society is an expert on internet access across the world. We ask how is the network holding up with so many more people now working remotely and what is its resilience for the future?
3D Printing cochlear implants
Gareth and Bill visit Dr Yan Yan Shery Huang at the biointerface group at the University of Cambridge. During the interview in her lab her team prints a 3D cochlear implant. It’s part of a growing field using 3D printing to improve medical care and aims to ultimately personalise cochlear implants allowing the patient to hear much more naturally than current implants allow.

March 03, 2020 Will digital sobriety help reduce energy use?
ITU emissions standard
The UN ICT agency, the ITU, wants to cut greenhouse gas emissions by nearly half in the next decade. It’s the only way that the ICT industry is to stay in line with the Paris Agreement and its target of limiting global warming to one and a half degrees. The new technical standard announced by the ITU says renewable energy and digital sobriety are the best way of achieving these cuts.
Domestic violence AI
AI could help police forces determine who might be the most at risk of domestic abuse. A new study from the Centre for Economic Performance at the LSE in London, suggests that by using already available data about individuals AI could help police decide which emergency calls they need to prioritise.
Circulo safety app
A safety app that is used only in dangerous situations is helping female journalists stay safe in Mexico. The Circulo app allows users to check in and tell up to six contacts at a time that you’re safe OR raise the alarm if you’re in danger.
