Neuroscience offers new insights into how our brain solves ‘the cocktail party problem’

Master1305/Shutterstock Imagine you are at a cocktail party. The room is crowded, people are coming and going, and you can barely hear your friend as they tell you some juicy gossip about the date they went on last week.

The long fascinating history of food additives – and why we’re stuck with them

Stir crazy? udra11 Battenberg cake is one of my favourite cakes. But when I tell people that one of the things I like most about this cake is its E-number, they tend to look at me strangely.

Open source tech helps farmers put more trust in digital tools

For a farmer wondering whether to invest in a new digital solution, a successful demonstration hundreds of kilometres away may not be particularly convincing. But seeing the same technology work on a neighbouring farm, or hearing a recommendation from a fellow farmer, a friend, or even a conversation in the local café, carries a different […]

Your brain runs on 20 watts. Could brain-inspired computing do the same?

Blue Andy/Shutterstock Right now, your brain is recognising the shapes of these letters, analysing their meaning, and holding a stream of thought together – all on about 20 watts of power. That’s roughly what it takes to run a lightbulb. Yet reproducing even a small fraction of the brain’s capabilities using today’s AI systems can […]

Tech leaders are calling for an ‘AI slowdown’ – but what would that mean in practice?

Alexander Supertramp / Shutterstock On Saturday, Donald Trump said, “We’re leading China on AI… and, frankly, I want to keep it that way because whoever wins AI, wins.” But the danger the world is waking up to is that this is a game both the US and China could lose, potentially fatally, with AI itself […]

China is exploring humanoid robots for war – but what role could they play?

At the World Humanoid Robot Games in Beijing, a humanoid robot named Tiangong Ultra ran the 100-metre sprint in a staggering 8.64 seconds, shattering Jamaican sprinter Usain Bolt’s legendary human world record of 9.58 seconds. The internet laughed at the robots’ awkward, lurching finishes and spectacular falls – but the laughter masked a chilling reality. […]

Who should own the knowledge that underpins AI technology?

Russian mathematician Yurii Nesterov's work on gradient descent methods is influential in the development of AI technology. Simons Foundation via Wikimedia Commons, CC BY-NC-ND Russian mathematician Yurii Nesterov was recently awarded the Gauss Prize for outstanding mathematical contributions for his “groundbreaking work” on optimisation. The award cited his work on gradient descent methods – and […]

New world map makes Africa look bigger: what’s the fuss about? Cartographers explain

The UN has passed a non-binding resolution to endorse the Equal Earth Projection, a map which more fairly represents the true size of the Earth’s landmasses. The current commonly used projection, called the Mercator Projection, greatly exaggerates land towards the north and south poles, which makes Africa look much smaller. In the Mercator projection, countries […]
