Episode 287 Chinese AI company DeepSeek unexpectedly stormed onto the scene just a few days ago - a move that has shaken the big US AI companies. The new large language model is similar to ChatGPT, but was developed for a fraction of the cost. How have they achieved this? We dig into the key technological innovations behind DeepSeek. We also discuss the potential climate gains of a more efficient AI model, whether this is the beginning of an AI-fuelled arms race between China and the US and perhaps most importantly - is it safe for you to use? All of this and a chat about the future of AGI - artificial general intelligence. Global ocean temperatures hit record highs for 450 days straight in 2023 and early 2024. This appears to be because the world’s oceans are absorbing heat from the sun at an accelerated rate. As warming hits the highest rates predicted by climate models, what is causing this sudden jump? Amazon river dolphins have been caught shooting pee into their friends’ snouts. A series of amazing images capture these dolphins, or botos, rolling upside-down and shooting a stream of pee into the air in a never-before-seen display. The team discuss why they’re doing it. Hosted by Rowan Hooper and Madeleine Cuff, with guests Alex Wilkins, Jeremy Hsu, Chris Merchant, Gavin Schmidt and Patty Brennan.

  • Hello.

  • Welcome to the latest Science insights from New Scientist.

  • I'm Rowan Hooper, joined today by Madeline Cuff.

  • Hello.

  • Hello.

  • Today we are talking to a couple of climate scientists about whether global heating is accelerating.

  • And we report on the first ever recording of a new form of dolphin behavior, aerial urination.

  • Well done.

  • I was really trying to get blue left without googling.

  • And also a nice pivot from climate change to dolphin.

  • We.

  • We're going to start though this week with the Chinese AI company Deepseek.

  • And it exploded onto the scene on Monday.

  • It wiped $600 billion off the market value of Nvidia, the chip company.

  • And if you think that this is just a tech story, we're going to get into why the development of AI is a climate story.

  • This is a really big story all round.

  • That's what I like to hear.

  • Every story is a climate story.

  • In my book.

  • That share price drop on Monday was the largest drop for a company on a single day.
