The excitement of auto racing comes from split-second decisions and daring passes by fearless drivers. Imagine that scene, but without the driver – the car alone, guided by the invisible hand of artificial intelligence. Can the rush of racing unfold without a driver steering the course? It turns out that it can. Enter autonomous racing, a field that’s not just about high-speed competition but also pushing the boundaries of what autonomous vehicles can achieve and improving their safety. Over a century ago, at the dawn of automobiles, as society shifted from horse-drawn to motor-powered vehicles, there was public doubt about the safety…

The New York Times’ (NYT) legal proceedings against OpenAI and Microsoft have opened a new frontier in the ongoing legal challenges brought on by the use of copyrighted data to “train”, or improve generative AI. There are already a variety of lawsuits against AI companies, including one brought by Getty Images against StabilityAI, which makes the Stable Diffusion online text-to-image generator. Authors George R.R. Martin and John Grisham have also brought legal cases against ChatGPT owner OpenAI over copyright claims. But the NYT case is not “more of the same” because it throws interesting new arguments into the mix. The legal action…

China’s national champions for computer chip – or semiconductor – design and manufacturing, HiSilicon and Semiconductor Manufacturing International Corporation (SMIC), are making waves in Washington. SMIC was long considered a laggard. Despite being the recipient of billions of dollars from the Chinese government since its founding in 2000, it remained far from the technological frontier. But that perception — and the self-assurance it gave the US — is changing. In August 2023, Huawei launched its high-end Huawei Mate 60 smartphone. According to the Center for Strategic and International Studies (an American think tank based in Washington DC), the launch “surprised the…

Sam Altman, chief executive of ChatGPT-maker OpenAI, is reportedly trying to find up to US$7 trillion of investment to manufacture the enormous volumes of computer chips he believes the world needs to run artificial intelligence (AI) systems. Altman also recently said the world will need more energy in the AI-saturated future he envisions – so much more that some kind of technological breakthrough like nuclear fusion may be required. Altman clearly has big plans for his company’s technology, but is the future of AI really this rosy? As a long-time “artificial intelligence” researcher, I have my doubts. Today’s AI systems – particularly generative AI…

NASA’s space shuttle operated in low-Earth orbit for 30 years before its retirement in 2011. However, the US space agency’s replacement for this vehicle, Orion, returned to the conical capsule design familiar from the Apollo missions. This was because NASA intended that this newer craft be used for exploring targets in deep space, such as the Moon. But in recent years, we have seen a return of the spaceplane design. Since 2010, the US Space Force (and formerly the US Air Force) has been launching a robotic spaceplane called the X-37B into low Earth orbit on classified missions. China has its own military spaceplane called Shenlong.…

The videogame industry had a banner year in 2023, with critically acclaimed blockbuster titles selling millions of copies. Yet, it was also a year of layoffs with 10,500 game makers losing their jobs. And with 5,900 reported layoffs in January alone, 2024 will likely surpass the previous year’s numbers. An endemic crunch mentality, exploitation, work intensification and growing unionization in the game industry collide with government and lobbyist reports about economic prosperity and employment growth. The industry contributed $5.5 billion to Canada’s GDP in 2021, an increase of 23 per cent from 2019. Global game revenue is predicted to rise from US$227 billion in 2023 to US$312 billion in…

In a newly published study, we describe our design for a self-extinguishing rechargeable battery. It replaces the most commonly used electrolyte, which is highly combustible – a medium composed of a lithium salt and an organic solvent – with materials found in a commercial fire extinguisher. An electrolyte allows lithium ions that carry an electric charge to move across a separator between the positive and negative terminals of a lithium-ion battery. By modifying affordable commercial coolants to function as battery electrolytes, we were able to produce a battery that puts out its own fire. Our electrolyte worked well across a wide…

The first human has received a Neuralink brain chip implant, according to co-founder Elon Musk. The neurotechnology company has started its first human trial since receiving approval from the U.S. Food and Drug Administration in 2023. The trial’s focus is on an implant that could potentially allow people with severe physical disabilities to control digital devices using their thoughts. The study involves implanting a brain chip — called a brain-computer interface implant — in the region of the brain that controls movement intention. Musk has said the patient who received the implant — fittingly named Telepathy — is “recovering well” and that “initial results show promising neuron spike…

Humans have always looked at the sky, using the stars as navigation guides or for spiritual storytelling. Every human civilization has looked to the stars and used celestial movements to measure time and find meaning. This insatiable thirst for knowledge combined with technological advancements have made it possible for us to dream of travelling in space. These dreams became more and more real after the Second World War, the Industrial Revolution, the Cold War and the large-scale exploitation of the Earth’s resources. Dreams of space travel started small with the launch of Sputnik-1 by the Soviet Union, and escalated with the U.S.…

Every minute, millions of social media posts, photos and videos flood the internet. On average, Facebook users share 694,000 stories, X (formerly Twitter) users post 360,000 posts, Snapchat users send 2.7 million snaps and YouTube users upload more than 500 hours of video. This vast ocean of online material needs to be constantly monitored for harmful or illegal content, like promoting terrorism and violence. The sheer volume of content means that it’s not possible for people to inspect and check all of it manually, which is why automated tools, including artificial intelligence (AI), are essential. But such tools also have their…
