Smart Cities at UP's Engineering 4.0: How to make a city street-smart

South Africa and the world will need to go a big step further to create smart cities where cars are safer and traffic congestion becomes a thing of the past: road infrastructure needs to “talk” to the vehicles driving on it, says UP's Professor Schalk Els.

'Imaging Black Holes With An Earth-Sized Telescope'

On 10 April 2019, the Event Horizon Telescope Collaboration revealed the first image of a black hole. This required a large international effort by over 200 scientists spread across five continents.

The team uses a technique called radio interferometry, synthesising a virtual telescope with the effective diameter of the Earth. By using antennas with separations on inter-continental scales,...

'World's first 3D-printed middle-ear transplant: Technological Advances in the 4IR'

On 13 March 2019, Professor Tshifularo performed three middleear transplants using 3D-printed ossicles (the hammer, anvil and stirrup). This procedure is significantly less risky than the use of prostheses and their associated surgical procedures and is hailed as the answer to conductive hearing loss, a middle-ear problem caused by congenital birth defects, infection, trauma or metabolic...

In the Shadow of the Black Hole.

The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today (10 April), in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.
