    5bn mobile phones to become waste in 2022
    The WEEE forum estimates that of the 16 billion mobile phones in the world about 5.3bn will no longer be in use this year. Despite being packed with precious metals like gold, silver and palladium and other recyclable parts most will not be disposed of properly. This mountain of e-waste (that if piled on top of each other would reach 120 times higher than the International Space Station) is only part of e-waste problem with other small consumer electronics e.g. remotes, headphones, clocks, irons etc., being hoarded in even greater numbers than mobiles. Magdalena Charytanowicz from the WEEE forum is on the show and explains the magnitude of the problem and how it needs to be tackled.100 years of the BBC As the BBC starts its 100th anniversary celebrations, we have a report from BBC Northampton’s Martin Heath, who is spending the day at the site of the Daventry transmitting station at Borough Hill. Martin tells us about the history of the station (it was initially was used for long wave, and short wave broadcasting and closed in 1992) and we also speak to one of the engineers who worked there about the technology used.The biggest radio telescope in the Northern Hemisphere The NOEMA radio telescope is now the most powerful radio telescope in the northern hemisphere. Twelve antennas in the French Alps will simultaneously detect and measure a large number of signatures of molecules and atoms. More than 5000 scientists from across the world will now be able to observe stars being born, comets, black holes and light from cosmic objects that has been travelling to Earth for more than 13 billion years. We find out about the tech that is making this possible.The programme is presented by Gareth Mitchell with expert commentary from Angelica Mari.Studio Manager: Gayl Gordon Producer: Ania Lichtarowicz(Image credit: Getty Images)

    Internet under attack in Ukraine
    Ukraine has faced internet outages since missile attacks restarted on Monday -a drop of more than 20% was recorded yesterday by The Internet Observatory Netblocks. This loss of connectivity is not thought to be due to cyber attacks but more about physical attacks on power infrastructure. Director of Netblocks, Alp Toker, is on the show to explain what’s happened.The boom in mobile money in Somalia Despite the worst drought in 40 years, Somalians are embracing mobile money to the point that it’s replacing formal currency. Without a central bank following the collapse of the government, the country was flooded with counterfeit money, this led to mobile money becoming popular. Two thirds of payments now being made via mobiles with 73% of the population over the age of 16 using mobile money services. Aid agencies are using the services to get money to remote rural populations in al-Shabab controlled areas impacted by the drought. We speak to Quartz East Africa Correspondent Tom Collins and Dean of Economics at SIMAD University in Mogadishu, Abdinur Ali Mohamed.Pass me that lobster: Conjuring up the metaverse On Tuesday Meta announce their metaverse plans. The sheer volume of images needed to fill the metaverse for it to be a success cannot be left to big tech if the metaverse is going to be a success. The metaverse will also have to rely on the next generation image making tools to fill the space for everyone who wants to use it in the way they want to use it . Bill Thompson explains how we will be able to take a lobster out of our backpack in the VR future. The programme is presented by Gareth Mitchell with expert commentary from Bill Thompson.Studio Manager: Michael Millham Producer: Ania Lichtarowicz(Image credit: Getty Images)

    Pandemic pushes women online
    In 2020 more than 40% of the world’s population was not using the internet, with many more women being unable to get online. Now a new global study into digital access in 90 countries shows that although women were disproportionately impacted by the Covid pandemic, it seems to have got more of them online in South East Asia and Africa. In these two parts of the world, the study shows progress in terms of bridging the gap between men and women and access to tech and the internet. While, historically, 90% of transactions in India were done by cash, the researchers say the pandemic forced more people to turn to digital payments for everyday items including food and other goods. In many parts of South East Asia, including India, many women are doing most of the shopping. The combination paved the way for progress and highlights a unique instance where the pandemic benefited women in these regions. Additionally, now equipped with their own digital wallets, women are afforded more agency over their finances. The progress in gender parity was seen in sub-Saharan Africa (8% improvement from 2019-2021), the Middle East and North Africa (6%), and South Asia (3%). We speak to Tufts University researchers who carried out the work, the dean of Global Business, Bhaskar Chakravorti, and research manager Christina Filipovic.War Games: Real Conflicts/Virtual Worlds/Extreme Environments Gareth and Ghislaine visit the Imperial War Museum in London to see the UK’s first-ever exhibition to explore video games and what they can tell us about conflict. Developing technology has introduced new ways of telling and experiencing war stories; toy soldiers and board games, cinema screenings of World War One, radio broadcasts from the frontlines of WWII, and TV images of the Cold War have given way to first-person shooter games on iconic consoles like the Atari 2600 and the Super Nintendo to internet driven team battles with the latest graphics and audio immersion. But is gaming tech the right place to explore conflict and how much is this entertainment industry driving tech development elsewhere?Presented by Gareth Mitchell with expert commentary from Ghislaine Boddington Producer: Ania Lichtarowicz(Photo: Rural woman talking on a mobile phone and using a laptop, India.

    Tiny robots cure mice with deadly pneumonia
    Microrobots have been created and used to treat the most common form of pneumonia that infects patients in ICU. In experiments, currently carried out in mice at the University of California San Diego, the tiny robots swam around the lungs and delivered antibiotics that killed the disease-causing bacteria. The amount of antibiotics needed is a tiny fraction of the amount currently used to treat this infection intravenously. The robots are made from algae cells (this allows them to move) covered in antibiotic-filled nanoparticles. These nanoparticles are made with tiny spheres that are coated with the cell membranes of neutrophils – a type of white blood cell that fights infection and inflammation - making the microrobots more effective at fighting the lung infection. We hear from lead author Professor Joseph Wang about the tech that’s allowed the team of nanoengineers to create these microrobots.Internet shutdowns in India – on what grounds are they allowed? Since 2012 there have been 683 full internet blackouts in India according to the internet shutdown tracker run by the Software Freedom Law Centre (SLFC). Many of these are done without following government rules. Now India’s Ministry of Electronics and Information Technology has only a week left to reveal the grounds on which it approves or imposes internet shutdowns in the country. The SFLC filed a lawsuit against the states of Arunachal Pradesh, Rajasthan, Gujarat and West Bengal, after internet shutdowns were ordered to prevent cheating during state exams. This is a common occurrence around the time of public exams across the country as stolen exam papers often appear on the internet. Now the Supreme Court has ruled that the protocols on which these decisions are made need to be made public. Tech reporter Emma Woollacott explains the massive impact of these shutdowns and lawyer Mishi Choudhary founder of the SFLC explains why they bought about the lawsuit.National Robotarium opens in Edinburgh Digital Planet’s Hannah Fisher has been given access to the UK’s first robotarium and reports on the eve of its opening for the programme. A big aim of the national robotarium at Heriot Watt University is to change public opinion about what robots actually are and how we can use them. The programme is presented by Gareth Mitchell with expert commentary from Ghislaine Boddington.Studio Manager: Andrew Garratt Producer: Ania Lichtarowicz(Image: Illustration of microrobots entering the lungs to treat pneumonia.
