Saving Submariners and Studying Deep Sea Species

The NATO Submarine Rescue System Sub. (c) Jonti Powis/Rolls Royce

How can we save the occupants of stricken submarines? What species survive in the deepest depths of ocean trenches? Recognising the centenary of the Titanic tragedy, we're diving deep to meet the Rolls-Royce NATO Submarine Rescue System, we find out about a new initiative to discover what really lives at the bottom of the ocean and hear how volcanoes are acidifying the seas. Plus, what robots can tell us about cocktail party conversations, the mystery of the pigeon's magnetic navigation, and can oil-based face-cream make you fat...?

  • 01:41 - Saving sailors in sunken submarines

    Submarines, manned or unmanned have been vital in learning about the deep sea as well as playing an essential role as part of our armed forces. But sometimes, subs get into trouble and its passengers aren't able to bailout. Jonty Powis explains how systems such as NATO are comi...

  • 09:34 - Studying life in the deepest depths of the ocean

    A major international collaboration is embarking on a mission to conduct the first systematic study of life in the deepest marine habitat on Earth; ocean trenches which are regions of the sea floor about 11,000 metres deep. We find out more......

  • 17:21 - Conversations over Cocktails: How we Converse in a Crowd

    Picking out a single voice in a noisy room can be a challenge. Our ears are assaulted by a wide range of noises that compete for our attention, yet somehow we are still able to enjoy a coherent conversation. Now, research suggests that the way we move our heads may have a sign...

  • 22:02 - A possible long-term treatment for Fragile X Syndrome

    Researchers have found a possible treatment for Fragile X syndrome – the most common genetic cause of mental retardation in boys and the main single-gene cause of autism.

  • 25:30 - Compass Confusion - The Pigeon's Magnetic Myth

    How do birds navigate long distances? It’s been known for a while that many different animal species are sensitive to Earth’s magnetic field and use this to find their way around. But recent work by scientists in Vienna has shown this may not, unlike previous theories, be the ...

  • 31:49 - The Signature of Colon Cancer

    Cancerous colon cells have a distinctive genetic signature, which could be used to develop personalised treatments, or identify those at risk of developing the disease...

  • 34:02 - Modifying Memories to Treat Drug Addiction and the Effects of Social Status on Health

    How memories can be re-written to prevent drug relapse, the effects of social rank on gene expression and health, how asteroid craters can help find life on other planets and using maths to help athletes run faster...

  • 38:35 - An Olympic Effort to Monitor Air Pollution

    The World Health Organisation estimates that every year almost two and a half million people worldwide die as a direct result of air pollution. In London, air quality regularly fails to meet European standards – which is of particular concern this year when the city hosts the O...

  • 44:10 - How do Volcanoes affect Ocean Biodiversity?

    How do subsea volcanoes affect the acidity of seawater? And how can this then affect the species found nearby? Robyn Williams from the Australian Broadcasting Corporation’s Science Show spoke to Jason Hall Spencer from Plymouth University to find out more...

  • 51:26 - Are robots the best way to study deep sea environments?

    A little while ago, the French were looking at designing robots to explore deep sea trenches in the Philippines. Is this the sort of technology that we need to be looking at, getting robots, getting automated devices, to do our research for us?
