Hacking internet-enabled cars
About 40% of cars in the US are connected to the internet. While this enables many useful functions, it also makes them vulnerable to hacks. As all the electronics systems within the car are connected, hackers could take full control of the vehicle. Skanda Vivek tells Gareth how this is possible, and what would happen if a large number of cars were hacked at the same time.

Covid-19 treatment trials in AI
It is possible to do drug trials in vitro and in vivo – but what about simulating them? The Cambridge-based company AI VIVO uses machine learning and AI to model diseased cells and their potential treatments. For Covid-19, they screened 90,000 different compounds to find out which drugs could be effective against the virus. Could this be a new way to discover drug treatments? Gareth speaks to David Cleevely to find out how it works.

Mobile phone rain forecast for farmers
Farmers with small holdings in developing countries often do not benefit from new technologies, but a tech project in Pakistan has managed to help drastically reduce their water consumption. Farmers receive text messages about when it is going to rain and whether they should irrigate their crops, generating an average of 40% in water savings. Roland Pease has been finding out more.

The programme is presented by Gareth Mitchell with expert commentary from Bill Thompson.
