Artificial intelligence (AI) is becoming ever more prevalent in our lives. It’s no longer confined to certain industries or research institutions; AI is now for everyone. It’s hard to dodge the deluge of AI content being produced, and harder yet to make sense of the many terms being thrown around. But we can’t have conversations about AI without understanding the concepts behind it. We’ve compiled a glossary of terms we think everyone should know, if they want to keep up. Algorithm An algorithm is a set of instructions given to a computer to solve a problem or to perform calculations that…

Each day, messages from Nigerian princes, peddlers of wonder drugs and promoters of can’t-miss investments choke email inboxes. Improvements to spam filters only seem to inspire new techniques to break through the protections. Now, the arms race between spam blockers and spam senders is about to escalate with the emergence of a new weapon: generative artificial intelligence. With recent advances in AI made famous by ChatGPT, spammers could have new tools to evade filters, grab people’s attention and convince them to click, buy or give up personal information. As director of the Advancing Human and Machine Reasoning lab at the University…

Do you remember learning to drive a car? You probably fumbled around for the controls, checked every mirror multiple times, made sure your foot was on the brake pedal, then ever-so-slowly rolled your car forward. Fast forward to now and you’re probably driving places and thinking, “how did I even get here? I don’t remember the drive”. The task of driving, which used to take a lot of mental energy and concentration, has now become subconscious, automatic – habitual. But how – and why – do you go from concentrating on a task to making it automatic? Habits are there…

The AI chatbot ChatGPT produces content that can appear to have been created by a human. There are many proposed uses for the technology, but its impressive capabilities raise important questions about ownership of the content. UK legislation has a definition for computer-generated works. Under the Copyright, Designs and Patents Act 1988 they are “generated by computer in circumstances such that there is no human author of the work”. The law suggests content generated by an artificial intelligence (AI) can be protected by copyright. However, the original sources of answers generated by AI chatbots can be difficult to trace – and they…

Physicists believe most of the matter in the universe is made up of an invisible substance that we only know about by its indirect effects on the stars and galaxies we can see. We’re not crazy! Without this “dark matter”, the universe as we see it would make no sense. But the nature of dark matter is a longstanding puzzle. However, a new study by Alfred Amruth at the University of Hong Kong and colleagues, published in Nature Astronomy, uses the gravitational bending of light to bring us a step closer to understanding. Invisible but omnipresent The reason we think dark matter…

The Justice Department on April 14, 2023, charged Jack Teixeira, a 21-year-old Massachusetts Air National Guard member, with unauthorized retention and transmission of national defense information and unauthorized removal and retention of classified documents or material. Media reports suggest that Teixeira didn’t intend to leak the documents widely but rather shared them on a closed Discord community focused on playing war games. Some of the documents were then shared to another Discord community with a larger following and became widely disseminated from there. So what is Discord and should you worry about what people are encountering there? Ever since the earliest days of the internet in the…

In March 2023, Italy became the first western country to block the advanced chatbot known as ChatGPT. The Italian data protection authority, Garante, cited concerns over the protection of personal data when making this decision. It has given OpenAI, the California-based company that created ChatGPT, until the end of April to comply with its demands. Garante said ChatGPT collects data in a way that’s incompatible with data protection law. Another reason given was the lack of age verification by the platform, which could expose children to harmful content. As a result, it used an emergency procedure to temporarily suspend the processing of personal data by OpenAI. News…

On April 20, 2023, a new SpaceX rocket called Starship exploded over the Gulf of Mexico three minutes into its first flight ever. SpaceX is calling the test launch a success, despite the fiery end result. As a space policy expert, I agree that the “rapid unscheduled disassembly” – the term SpaceX uses when its rockets explode – was a very successful failure. The most powerful rocket ever built This launch was the first fully integrated test of SpaceX’s new Starship. Starship is the most powerful rocket ever developed and is designed to be fully reusable. It is made of two different stages,…

As public concern about the ethical and social implications of artificial intelligence keeps growing, it might seem like it’s time to slow down. But inside tech companies themselves, the sentiment is quite the opposite. As Big Tech’s AI race heats up, it would be an “absolutely fatal error in this moment to worry about things that can be fixed later,” a Microsoft executive wrote in an internal email about generative AI, as The New York Times reported. In other words, it’s time to “move fast and break things,” to quote Mark Zuckerberg’s old motto. Of course, when you break things, you might have…

Lunar exploration is undergoing a renaissance. Dozens of missions, organised by multiple space agencies – and increasingly by commercial companies – are set to visit the Moon by the end of this decade. Most of these will involve small robotic spacecraft, but NASA’s ambitious Artemis programme, aims to return humans to the lunar surface by the middle of the decade. There are various reasons for all this activity, including geopolitical posturing and the search for lunar resources, such as water-ice at the lunar poles, which can be extracted and turned into hydrogen and oxygen propellant for rockets. However, science is also sure to…
