Elon Musk’s acquisition of Twitter has been rocky, to say the least. Since taking over the company on Oct. 28, Musk has made a number of changes to the platform, resulting in widespread chaos and turmoil within the company. Within days of taking over Twitter’s operations, Musk fired top executives and half of the company’s 7,500 employees, ignored advice to not disproportionately fire employees representing diversity and inclusion and has likely violated employment labour laws and breached employee contracts. Then on Nov. 16, Musk sent an email to remaining workers with an ultimatum: commit to being “extremely hardcore” or leave the company. The letter continued: “This will mean working long…

The European Space Agency (Esa) recently announced a new mission of its science programme: a small telescope orbiting the Earth dubbed Arrakhis. But although its name is inspired by the sci-fi novel Dune, it will not be looking for sandworms or “spice” on a desert planet. Instead, this nimble satellite will punch hugely above its weight and try to track down one of the most elusive and mysterious substances in the universe: dark matter. This is the term given to the hypothetical invisible matter that is thought to be more abundant than normal matter and have a similar gravitational effect on its surroundings. The…

Drones are already shaping the face of our cities – used for building planning, heritage, construction and safety enhancement. But, as studies by the UK’s Department of Transport have found, swathes of the public have a limited understanding of how drones might be practically applied. It’s crucial that the ways drones are affecting our future are understood by the majority of people. As experts in design futures and mobility, we hope this short overview of five ways drones will affect building design offers some knowledge of how things are likely to change. 1. Creating digital models of buildings Drones can take photographs of buildings,…

When the first five images from the James Webb Space Telescope (JWST) were unveiled, one of them stared at me with two eyes. It was an image of the Southern Ring Nebula, NGC3132, and smack in the middle were two bright stars. Now, the fact that NGC3132 houses a binary star system (two stars orbiting one another) has been known since the days of the Hubble Space Telescope. But in those early images, the central star that ejected the nebula – a tiny, hot white dwarf – was so dim it was almost invisible next to its bright Sun-like companion.…

It is common to hear news reports about large data breaches, but what happens once your personal data is stolen? Our research shows that, like most legal commodities, stolen data products flow through a supply chain consisting of producers, wholesalers and consumers. But this supply chain involves the interconnection of multiple criminal organizations operating in illicit underground marketplaces. The stolen data supply chain begins with producers – hackers who exploit vulnerable systems and steal sensitive information such as credit card numbers, bank account information and Social Security numbers. Next, the stolen data is advertised by wholesalers and distributors who sell the data.…

The question of whether artificial intelligence (AI) can invent is nearly 200 years old, going back to the very beginning of computing. Victorian mathematician Ada Lovelace wrote what’s generally considered the first computer program. As she did, she wondered about the limits of what computers could do. In 1843 Lovelace wrote, in regard to what is arguably the first general purpose programmable computer: The Analytical Engine has no pretensions to originate anything. It can do whatever we know how to order it to perform. It can follow analysis; but it has no power of anticipating any analytical relations or truths. Its province is…

At about 10 o’clock on the night of February 28 2021, a fireball streaked through the sky over England. The blazing extraterrestrial visitor was seen by more than 1,000 people, and its descent was filmed by 16 dedicated meteor-tracking cameras from the UK Fireball Alliance and many dashboard and doorbell cams. With the time difference to Australia, the Global Fireball Observatory team at Curtin University were the first to dig into their cameras’ data, quickly realising there may be very special meteorites to find around the town of Winchcombe, Gloucestershire. The next morning’s news told people in the area to look out for black rocks in…

A photograph taken by NASA’s Orion spacecraft has given us a new perspective on our home planet. The snap was taken during the Artemis I mission, which sent an uncrewed vehicle on a journey around the Moon and back in preparation for astronauts’ planned lunar return in 2025. We get pictures of Earth every day from satellites and the International Space Station. But there’s something different about seeing ourselves from the other side of the Moon. How does this image compare to other iconic views of Earth from the outside? Earthrise In December 1968, three astronauts were orbiting the Moon…

President Joe Biden is hosting the Second US-Africa Leaders Summit in mid-December 2022. The focus will be on eight areas: economic engagement; peace, security and good governance; democracy and human rights; regional and global health security (including recovery from COVID-19 and pandemic preparedness); food security; climate change; diaspora ties; and education and youth leadership. Of the 55 African heads of governments, 49 have been invited to the summit. Burkina Faso, Guinea, Mali and Sudan are currently on suspension from the Africa Union due to coups d’etats, hence they were not invited. Western Sahara (officially called Sahrawi Arab Democratic Republic), though a member of the African Union,…

Our society faces the grand challenge of providing sustainable, secure and affordable means of generating energy, while trying to reduce carbon dioxide emissions to net zero around 2050. To date, developments in fusion power, which potentially ticks all these boxes, have been funded almost exclusively by the public sector. However, something is changing. Private equity investment in the global fusion industry has more than doubled in just one year – from US$2.1 billion in 2021 to US$4.7 billion in 2022, according to a survey from the Fusion Industry Association. So, what is driving this recent change? There’s lots to be excited about. Before we…
