A Million Processor Supercomputer

Largest neuromorphic supercomputer The world’s largest neuromorphic supercomputer has just been switched on. Called the Spiking Neural Network Architecture or SpinNNaker, it’s built to work like the human brain and can complete more that 200 million million actions per second, making it the fastest of its kind in the world. First AI medical app in Swahili Ada, an AI powered health platform, is launching in Swahili, making its health assessment technology available to more than 100 million...


Is VR Dying?

The promise of a new virtual world where we could escape and become someone completely different may never become a reality, according to tech journalist Joshua Topolsky. On Click, BAFTA award winning immersive artist Catherine Allen argues that VR is not dying, but it will not be the experience we thought it would be. Managing Social Media After a Terrorist Attack How should police and other authorities manage social media during and after a terrorist attack? A new report, entitled From...


Migrant Caravan Communications

Three thousand migrants from Latin America are attempting to enter the US en masse. How are they organising it - is it just word of mouth or does technology play a part? Digital forensics, why an online washing machine could land you in hot water. Robot flies become real but they won’t be landing in your drinks any time soon. The role of fake news in starting World War II. How the Nazis conned the allies into allowing them to invade Czechoslovakia, with a very modern sounding deception....


Keeping Internet Traffic Within Africa

The Internet Society has partnered with Facebook to expand internet connectivity in Africa using internet exchange points (IXP). IXPs could allow data to stay within the continent instead of being sent outside and then back again. Our attitudes towards technology appear to have changed completely – from tech worship to tech fear. Will we be able to find a healthy balance? Jess Tyrell, author of a new discussion paper about our approach to tech and Julian Blake, editor at DigitalAgenda, who...


Apple and Amazon Deny China Hack Claims

Apple and Amazon have strongly denied they have been subject to a Chinese cyber-attack, following a report by Bloomberg Businessweek. BBC Technology Correspondent Mark Ward tells Click more and if such a spy chip attack could even be possible. Scientists at Drexel University in the US have created spray on antennas that perform as well as current antennas found in phones, routers and other gadgets. They have used a 2D metallic material called MXene which they say can be painted onto everyday...


Could Tech Warn of Future Tsunami?

Could a complex prototype system of sensors and cables on the sea floor in Indonesia warn scientists of future tsunamis? Professor Louise Comfort from the University of Pittsburgh explains how this might work. What could be the consequences of hidden messages encoded into audio that voice recognition systems can hear, but we can’t? Professor Dorothea Kolossa from the University of Bochum has been hacking into these systems to find out. Is the age of tech fibre really upon us? Professor Yoel...


Digital v Analogue

The digital era gives us everything to own, but nothing to touch. At the same time there is an increasing craving for tactile, physical analogue experiences. In recent years there has been a return to vinyl with record shops opening up across the world; in Berlin alone there are more than 100. It is not just nostalgia. Many new sales are coming from young people who have been brought up in a digital age. Perhaps for a heathy life we need an analogue ying to our digital yang. In the BBC Radio...


Atomic Radio

Using a laser to detect the effect of radio waves on certain atoms is the basis for a new kind of antenna that resists interference and can receive a wider range of signals. Click talks to David Anderson who has reinvented the antenna from scratch. 4D printing allows 3D objects to can change shape reacting to external inputs such as pressure, temperature, light or other environmental stimuli, making 4D printed creations interactive. Researchers in Wellington, New Zealand are using biology as...
