A leap of faith: Should we trust AI with a million-year problem?

A leap of faith: Should we trust AI with a million-year problem?

Artificial intelligence (AI) has been here a while, and it isn’t going anywhere, not any time soon. It has become an integral part of many lives and businesses. When I speak of AI, I am not referring to GenAI (generative AI) that writes your emails for you: Think about the algorithms that suggest what movie you should watch next, the voice assistant that adds milk to your shopping list, and ...[Read More]

AI: the good, the bad, and the forgotten

AI: the good, the bad, and the forgotten

AI is here, and when I say here, I mean e-v-e-r-y-w-h-e-r-e. For all you know, this blog may have been written by an algorithm (it wasn’t — I’m not a robot, promise. Or am I?). In what feels like the blink of an eye, AI has gone from a curiosity to a fully-fledged co-pilot in science (and out of science). It’s generating satellite imagery, helping compute paleo-climate predictions, or writing your ...[Read More]

How can scientists see ice underground? Recent study reveals how!

How can scientists see ice underground? Recent study reveals how!

When it comes to peering beneath the Earth’s surface, geophysicists have an arsenal of high-tech tools at their disposal. But what happens when you need to track something as elusive as underground ice forming and melting in real time? Enter borehole Ground-Penetrating Radar (GPR), the underground detective that helped Peter Jung and his colleagues image frozen subsurface volumes in an experimenta ...[Read More]

A 12-meter sediment core reveals secrets of the Arctic’s past climate

A 12-meter sediment core reveals secrets of the Arctic’s past climate

Extracted from a depth of 2,500 meters, a giant 12-meter long marine sediment core from the Fram Strait, between Svalbard and Greenland, preserves a climate record spanning up to 400,000 years. Its sediment layers offer crucial insights into the Arctic’s past, helping Dr Jochen Knies and his research team answer two important question: Was the Arctic ever ice-free during past warm periods? W ...[Read More]
