Low Energy, High-Power Processing

Hard disk drives are common storage devices used with computers. (c) Alpha six from Germany

This week we're getting inside the workings of the next generation of chips that are set to pack a bigger computing-punch but at a fraction of the energy-expenditure of todays' models: CTO Mike Muller joins us to explain the revolutionary technology that leading microprocessor-maker ARM is developing. Also, energy-efficient world-wide computing - we find out how distributing data-processing demands around the planet can turn waste energy into useful computations, simultaneously saving CO2 emissions. Plus, in the news this week, a new malarial mosquito threat, rejection-free artificial blood vessels and the electric cap that helps users solve maths puzzle they previously found impossible.

  • 01:47 - New Malaria-susceptible mosquito found

    Researchers this week have reported in the journal Science the existence of a new subspecies of mosquito, that is highly susceptible to the most dangerous form of malaria parasites.

  • 04:27 - Hard graft yields new artificial arteries

    The field of arterial graft surgery looks set to take a big leap forward thanks to a breakthrough by US scientists. Writing in Science Translational Medicine, Shannon Dahl, a researcher with the North Carolina-based bioengineering company Humacyte, has described a method for ma...

  • 17:47 - Programmable packaging for cells

    Scientists have developed the cellular equivalent of a shrink-wrapping system which is capable of packaging up chemicals inside the cell...

  • 20:01 - Plant Earth Online - Sounds under the Sea

    Documentaries filmed underwater tend to give the impression that its a quiet, even, serene environment beneath the waves, but stick a microphone in the sea and you'd be amazed what you can hear...

  • 25:35 - Naked Engeering - Designing Computer Chips

    What is a computer chip and how does it really work? Meera and Dave investigate...

  • 33:50 - Energy Efficient Microchips

    ARM Holdings are a world leader in developing digital solutions and two of the projects they're working on at the moment are ways to make computer chips smaller and much more energy efficient....

  • 40:22 - Computing With Waste Energy

    As the internet and our reliance on computers grows, so does the amount of energy that this industry consumes, which means significant CO2 emissions. But is there a way to make the process more environmentally friendly? Computer Scientist Professor Andy Hopper from Cambridge U...

  • 47:43 - Do we really need faster computing power?

    Do we really need faster computing power, or are our programming methods just inefficient? What do we need to do to make sure we're programming our computers in the most efficient way possible?
