December 17, 2019 Improving crop yields with mobile phones
Mobile phones are improving lives and yields for millions of farmers around the world. Michael Kremer, a 2019 Economics Nobel Prize winner developed Precision Agriculture for Development (PAD) to give farmers in developing countries advice on how to improve their yields. He and Owen Barder, CEO of PAD, tell Digital Planet how it works.
To reduce failures on surveillance or delivery missions, drones need to be monitored effectively. Karen Willcox at the Oden Institute of the University of Texas in Austin explains how her team has found a way to send back real time data using sensors that create a digital twin of the drone, which can show where fatigue and stress may cause damage during the flight.
Racist and sexist biases within algorithms are causing concern, especially considering they are making many decisions in our lives. Noel Sharkey, Professor of Robotics and AI at the University of Sheffield in the UK, and he thinks it’s time to halt this decision making until it can be properly regulated, or it will have major, real-life effects on all of us.

December 10, 2019 New Phone in China? Scan your face…
Mobile phone users in China will have to submit to 3D face scans to get a sim card. Technology ethicist Dr Stephanie Hare and New York Times Asia correspondent, Paul Mozur, discuss how this will affect citizens’ privacy, and whether China is alone in making this decision.
Petr Plecháč from the Institute of Czech Literature uses a piece of software that can identify people by the pattern of their written language. Gareth speaks with him about Shakespeare’s Henry VIII and the likelihood of John Fletcher co-authoring this key text.
Reporter William Park takes a go at being a virtual burglar. He investigates a game that is allowing researchers to understand what thieves do during a break-in, with the aim of understanding their moves and decision making.
A technique that allows people to check how computer neural networks make decisions about image classification may help to reduce mistakes by AI in medical imaging. Dr Cynthia Rudin explains why bird identification was the perfect model to test the computers’ abilities – and check them.

December 03, 2019 Humanitarian drone corridor in Africa
Humanitarian drone corridor in Africa
Sierra Leone has just launched West Africa’s first drone corridor – it’s a dedicated channel of airspace for medical delivery drones. UNICEF is part of the project and already has three other humanitarian corridors open globally.
Wikipedia untagging of women
Dr. Jess Wade from Imperial College London is continuing her mission of getting more female scientists onto Wikipedia, however a few days ago many of her entries were marked as not notable enough to be included. This was done anonymously by another Wiki editor. We hear from Jess and Wikipedia’s Katherine Maher.
Cats detecting earthquakes
Could cats detect earthquakes? Yes says Celeste Labedz a seismologist at Caltech – if they are fitted with a motion tracker device. It’s purely a theoretical idea as she explains on the programme.
Smart tattoos
Smart ink that changes colour could lead to medical smart tattoos that monito conditions like diabetes. Harrison Lewis has been finding out more.

November 26, 2019 Google bug bounty hunters
Google’s offering up to $1.5m to anyone who can identify bugs in its new chip for Android smartphones. This is a especially high reward but Google’s just one of a host of big well-known companies running bug hunting programmes. But is this the best way for big business to protect its new tech?
AI in Africa
Does Africa need a different approach to AI – yes according to Professor Alan Blackwell of the Computer Laboratory at Cambridge University in England. He’s just started a sabbatical year across Africa working with AI experts – we spoke to him on the first leg of his trip at the Bahir Institute of Technology (BIT) in the North West of Ethiopia.
Wi-fi on the bus
Being online when travelling on the bus in parts of Kenya and Rwanda is not new, but now it is also possible in parts of South Africa as BRCK launch their public internet service there.
Nanotech tracing stolen cars
Around 143,000 vehicles worldwide were reported as stolen in 2018 according to Interpol. In the UK, only half are recovered. Now nanosatellites could be a new tool in retrieving stolen cars. Digital Planet’s Izzie Clarke has more.

November 19, 2019 Iran internet shutdown continues
Iran internet shutdown
Iran is now almost entirely offline as authorities try to stem the spread of protests that started last week. The government increased fuel prices by as much as 300% and since people took to the streets online access has been restricted. We find out the latest from online monitoring group NetBlocks.
US Election emails unsafe
Agari was the company that uncovered and confirmed that the webserver the email that ‘hacked’ Hilary Clinton’s campaign came from Russia. They have now conducted a poll and found that only Elizabeth Warren out of all the potential presidential candidates has secure emails. This matters not only from a data security point of view but also from a voter and donor point – the company has found that voters are less likely to vote for a candidate with a data breach and that donors are less likely to give money.
Hate speech control using tech
Hate speech that incites violence or hate against vulnerable groups has long been a problem in human societies but has more recently been weaponised by social media. The current system means the direct or indirect recipient needs to complain. The alternative approach is to develop artificial intelligence to identify potential hate speech and put the post in quarantine until either the direct recipient has agreed it should be deleted or has read it and agreed it should be allowed.
Cargo Ship tech
Our reporter Snezana Curcic has travelled across the North Atlantic Ocean in a bit of an unusual and adventurous way – on a cargo ship. With only eight hours of Wi-Fi allowance per week, Snezana filed this story on her journey from Liverpool to New York on the Atlantic Star. She looks at the tech on board and how this hugely competitive and complex industry is adapting to the digital age to survive. Even e-commerce leaders, like Ali Baba and Amazon, are heavily investing in ocean cargo services and stepping up their game.

Mookh opens up e-commerce opportunities in Kenya
Mookh is a Nairobi-based company that allows users to sell their products online. Founder Eric Thimba describes how the platform has allowed many Kenyan creatives to monetize their products and the boon of mobile money to the African economy. The platform has recently launched in Uganda and Rwanda.
Curiosity photographs dunes on Mars
The Curiosity rover has been exploring Mars since its landing in 2011. Professor Sanjeev Gupta of Imperial College London explains how planners and software engineers work together to conduct experiments remotely, and muses on the potential of sending a real human to the red planet.

UNICEF start crypto-currency fund
UNICEF, the United Nations Children’s Fund, will now be able to receive donations in crypto-currencies like Bitcoin and Ethereum. Christopher Fabian, co-founder of UNICEF’s innovation unit, explains how this will allow the organisation to buy data directly from suppliers for schools that are currently offline.

New spy technology uses wi-fi signals
Wi-fi signals are distorted as they bounce off objects. Dr Yasamin Mostofi from the University of California has created a way to use these distortions to ‘see’ and possibly identify a person moving behind a wall.

Tunabot
Professor Hilary Bart-Smith at the University of Virginia, USA went back to basics to develop a fast swimming robotic tuna - the tunabot. They took detailed anatomical data from the Yellow-finned tuna and Atlantic mackerel and 3D printed the fast tunabot. The tunabot swims faster than existing tunabots by increasing the frequency with which its tail beats.
Tech to help deal with dementia
An estimated 130 million of us could have dementia by 2050, but technology could help people live with the condition. Videos that pop up on your phone to help you perform everyday tasks like boiling the kettle or QR codes on your clothes that help others identify you and contact your family if you get lost are just some of the advances that Jason Hosken reports on.
Ushahidi
Ushahidi is Swahili for witness and it’s also the name of an open source software. It was originally created ten years ago to report reprisals and violence around elections. Since then it’s widened out into all kinds of crisis mapping – everything from monitoring natural disasters to illegal deforestation. Angela Odour Lungati is the recently appointed Executive Director at Ushahidi.
