February 25, 2020 Ethiopia’s new law banning online hate speech
Ethiopia’s online hate speech law
Disseminating hate speech online in Ethiopia could now land you with a prison sentence of up to three years and a fine of $3000US, but the new law has proved controversial. Julie Owonp, Excutive Director of Internet without borders explains their concerns.
Kivuwatt
Rwanda has an ambitious plan to go from half of the population having electricity at the moment to everyone within the next four years. Digital Planet has been given access to one project that aims to be a key part of that expansion. In the depths of Lake Kivu – one of East Africa’s great lakes – there’s methane and they’re burning the methane to generate electricity. Kivu is one of Africa’s so-called ‘killer lakes’, because the gases it harbours could be deadly for the thousands who live on shore. Burning some of the gas could help make it safer. Gareth Mitchell reports from the floating barge that is supplying 30% of the country’s electricity.
Carnival 4.0
It’s Carnival week in Rio and this year for the first time celebrations have gone fully hi-tech with augmented reality floats, QR Codes and RFID tags tracking costumes and smart bands monitoring the health of performers. But there have also been warnings about facial recognition. Brazil-based journalist Angelica Mari has been following proceedings. And joins us on the programme.

February 18, 2020 Feminist chatbots
Why the tone of chatbots matters and how a feminist perspective can help use them to address online problems such as bullying and trolling.
We look at some of the methods used to try and scam you, particularly the increasingly sophisticated emails sent to businesses to try and get them to part with their money.
We have a drive in a LIDAR enabled electric car, a new development in Autonomous vehicles
And the perils of misleading data, why clear and accurate data is so important to a huge variety of global issues such as adequate clean water or food supplies.

February 11, 2020 Repairing Voyager 2
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.

February 04, 2020 Drones dealing with locust swarms
Trials are taking place to manage the massive locust swarms in the Horn of Africa and the Indian subcontinent with drones. Using them to collect real time data allows scientists to predict where the insects might fly to next.
Irish data centre power problem
Amazon has just announced plans to build another data centre in Ireland. It’s just one of about 60 data centres that are putting a huge demand on electricity. According to a report by the Irish Academy of Engineering 30% more electricity will be needed by 2030 to keep these data centres running. But where will it come from if Ireland is to meet its carbon emission targets?
More data leaks in India
A new data privacy bill has been passed in India, but with hundreds of millions of individuals having their data leaked last year alone, will this new bill ensure data privacy? BBC data journalist Shadab Nazmi has exposed a number of information security blunders in India and explains what has been happening.
Acoustic camera
Imagine that you could only hear specific sounds in certain parts of a room. So an intensive care nurse would only hear the beeps from the medical bay of their patient? This might be possible as scientists at the University of Sussex in England are splitting sounds, focusing them into beams and even bending them. Our reporter Hannah Fisher has been there to explore.

January 28, 2020 Internet partially restored in Kashmir
Internet in Kashmir partially back on
Following a court ruling in India, the internet has been partially restored in Kashmir. There is still no access to social media but the Indian government was forced to allow some access. Mishi Choudhary, founder of the Software Freedom Law Centre in New Delhi updates us on the situation.
Pigeonbot
Imagine a robot that’s as graceful as a swooping and gliding bird. It could get into crowded environments where drones currently can’t be used. The latest research, published in Science Robotics, into flying robots delivers just that. Laura Matloff from Stanford University in USA is one of the team who designed PigeonBot and joins us on the programme.
Will Brazil become a data colony?
Brazilians are neither happy with the way in which companies handle their personal data or trust them, according to a new survey by IBM. Sau Paulo based Technology Writer Angelica Mari explains why there are growing concerns that soon private companies may control most citizen’s data.

January 21, 2020 Internet shutdowns cost $8bn in 2019
The cost of the major internet shutdowns in 2019 has been estimated as $8bn according to a report by the Top10VPN website, with WhatsApp being the platform that is blocked most often.
Twitter bots and trolls on bush fires
Could the latest orchestrated social media disinformation campaign be unfolding in Australia. Researchers at the Queensland University of Technology have been analysing thousands of tweets and found some concerning activity. Could paid for trolls be behind tweets suggesting that arsonists are responsible for this year’s bush fires?
Indigenous language keyboards
The United Nations has just declared an International Decade of Indigenous Languages. It is to begin in 2022, so we have been finding out about getting indigenous languages onto a device – and it isn’t always as hard as you think.
Worm robots
Robotic worms might be soon being used to sniff out people as part of search and rescue operations. Our reporter Jason Hosken has been to the lab where they’re developing chemical sensors that could help trace people who have perhaps been trapped under rubble following a natural disaster. The robotic worm could end up assisting, or reducing the need for, specially trained sniffer dogs.

January 14, 2020 Tech tracking Australian fires
An app is helping Australian’s stay safe during the Bush fires. Fires Near Me was created by the New South Wales Rural Fire Service and we hear how it works from journalist Corinne Podger. Also the WICEN HAM Radio operators who are providing emergency communications when mobile masts and internet connections are disrupted and measuring air quality using low power networks.
Safer motorbike taxis in Rwanda and the DRC
How do you ensure that the motorbike taxi you are hailing in Kigali or Kinshasa will get you home safely? Using an app that has data on the driver is one big step to having a safer journey. Gareth Mitchell finds out about Cango who collect data about their drivers to rate how safely they ride.
Digitising Natural History
The famous Natural History Museum in London has only a fraction of its collection on show. To ensure all their specimens are correctly catalogued, the museum is now digitising their collections. Harry Lampert has been finding out how technologies like machine learning are helping to get more and more specimens online.

January 07, 2020 South Africa power cuts
South Africa Power Cuts
Is South Africa facing a blackout? Power cuts across the country are now happening regularly as the country struggles with demand for electricity. There’s even an app that tells you if your lights are going to stay on today, or tomorrow. Professor Keith Bell from Strathclyde University explains why this is happening.
Plasmonics - computing with light
Fancy computing with the speed of light? Well for the first time this is possible thanks to research at Oxford University. Scientists have managed use light to store, access and now process data on chip. The research could significantly increase processing speeds at data centres, not only making computing faster but saving significant amounts of energy.
Land of Iron
A National Park is usually synonymous with nature and wildlife. Perhaps not the obvious place to find a technology story, but in North Yorkshire in the UK a project is underway that is using technology in many different forms to bring a forgotten history back to life. Our reporter Jack Meegan has been time-travelling for us. Jack finds out how the park’s industrial past can now be seen thanks to technology.
