BlueDot’s AI algorithm, a type of computer program that improves as it processes more data, brings together news stories in dozens of languages, reports from plant and animal disease tracking networks and airline ticketing data. The result is an algorithm that’s better at simulating disease spread than algorithms that rely on public health data – better enough to be able to predict outbreaks. The company uses the technology to predict and track infectious diseases for its government and private sector customers.

Facial recognition is increasingly being used in many countries around the world. In some cases the take up has been dramatic. As a result, people are being observed by cameras more than ever, whether in stores, on public transit, or at their workplaces.

The first generation of people who have grown up using social media such as Facebook and Instagram are entering the workforce. For as long as this breed of so-called “digital natives” has been alive, some academics have been arguing that using the internet from a young age would shape the way people learn, work and even think.

If you’re concerned that automation and artificial intelligence are going to disrupt the economy over the next decade, join the club. But while policymakers and academics agree there’ll be significant disruption, they differ about its impact.

Aside from being a central information and alert system, Twitter also provides a platform for the narratives of those personally affected by disasters or outbreaks, which is useful when it comes to humanitarian assistance and support.

South Africa is ranked 19 out of 46 countries on the RIA African Mobile Pricing (RAMP) Index. The prices of the first-entrant operators – MTN and Vodacom – remain high relative to Cell C and Telkom Mobile, which dropped their prices in the first half of last year.

“Atomaterials” is short for “atomic materials”, so called because their properties depend on the precise configuration of their atoms. It is a new but rapidly developing field.

Like quantum computing, quantum communication records information in what are known as qubits, similar to the way digital systems use bits and bytes. Whereas a bit can only take the value of zero or one, a qubit can also use the principles of quantum physics to take the value of zero and one at the same time.

While Facebook and Twitter host a broad range of user activities, a study asked, what does off-label use look like on an app like Tinder, which has an articulated label? Further, how does off-label use play out when other users expect that the app has fixed purposes?

These four altcoins are the largest cryptocurrencies on the market after bitcoin, representing an aggregate US$51 billion market capitalisation (the value of each coin multiplied by the number of coins on the market). This is still fairly small compared with bitcoin’s US$178 billion market cap, but clearly the gap has been narrowing.
