  • Rethinking the Brain Machine Interface | Polina Anikeeva | TEDxCambridge

    The way humans interact with computers has evolved from punch cards, to the keyboard and mouse, to much more sophisticated user interfaces, but the kinds of connections imagined in movies like The Matrix, Avatar or Pacific Rim still seem like science fiction. Polina Anikeeva is working to turn fiction into fact, not to help with virtual reality technology, but to help amputees restore full functionality to prosthetic limbs - not just to control the muscles, but to be able to feel and touch again. To achieve this, you need the precision of a virtuoso pianist to connect neural tissue to the prosthetic limb. The key to this precision is finding the right materials. Dr. Polina Anikeeva is an assistant professor of Materials Science and Engineering at MIT and a principle investigator of the Bi...

  • The Super-Resolution Revolution

    Cambridge scientists are part of a resolution revolution. Building powerful instruments that shatter the physical limits of optical microscopy, they are beginning to watch molecular processes as they happen, and in three dimensions. Here, Professor Clemens Kaminski describes how a new era of super-resolution microscopy has begun. The developments earned inventors Eric Betzig and William E Moerner (USA) and Stefan Hell (Germany) the 2014 Nobel Prize for Chemistry, and are based on clever physical tricks that work around the problem of light diffraction. Among the scientists in Cambridge who are using the techniques, Kaminski’s team in the Department of Chemical Engineering and Biotechnology designs and builds super-resolution microscopes to study Alzheimer’s disease. “The technology is ba...

  • Prof. Ortwin Hess - The Stopped-Light Laser: An optical black hole on the nanoscale

    Talk abstract by Prof. Hess: Ever since their first conception 50 years ago, lasers have evolved from little more than a scientific curiosity in the laboratory to take a place at centre stage in today’s society. Lasers do come in all kind of sizes and for an incredible variety of wavelengths – colours of the emitted light – but all have two vital components: a (laser) gain material and coherent feedback of the emitted light. In normal lasers feedback is provided by placing the gain material between mirrors – i.e. inside a cavity. Now, could we accomplish such feedback by keeping photons that have just been emitted from an active laser medium, simply from propagating away? Light is normally the fastest ‘object’ in the universe, but researchers have, indeed, recently conceived ways of slowi...

  • Vox Cambridge 30 Repair (Please read description)

    This video deals with replacing the optical coupler in a Vox Cambridge 30 guitar amp. The component can be sourced from Thonk in the UK. Not too expensive and a quick service. Make sure you get the component the right way round. When you remove the back cover, the led section of the component is on the right hand side legs. The positive leg goes closest to the potentiometer above it. Took me around an hour total to replace and rebuild. Was disappointed when I tried it out, but then adjusted the potentiometers as per the video and it's like a different amp. This is guidance only. I do not accept any responsibility for injury, damage or death by fiddling with your amplifier. I'm really pleased with the improvement this repair has made. I'm definitely keeping this amp now.

Her research lies in the field of neuroprosthetics and brain-machine interfaces. Together with her group she explores optoelectronic, fiber-based and magnetic approaches to minimally invasive neural interrogation. Her group was first to demonstrate multifunctional flexible fibers for simultaneous optical stimulation, electrical recording and drug delivery in the brain and spinal cord, as well as magnetic nanomaterials for wireless magnetic deep brain stimulation. Her work at the interface of materials science and neurobiology earned a number of junior faculty awards including NSF CAREER and DARPA Young Faculty Award and was recently featured across popular press. She received her doctoral degree in Materials Science from MIT. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

By imaging blobs of light as separate points in time, we are able to discriminate them spatially, and thus prevent image blur.” Their work is funded by the Medical Research Council, Wellcome Trust, Alzheimers Research UK, the Engineering and Physical Sciences Research Council and the Leverhulme Trust. http://www.youtube.com/subscription_center?add_user=cambridgeuniversity

Talk abstract by Prof. Hess: Ever since their first conception 50 years ago, lasers have evolved from little more than a scientific curiosity in the laboratory to take a place at centre stage in today’s society. Lasers do come in all kind of sizes and for an incredible variety of wavelengths – colours of the emitted light – but all have two vital components: a (laser) gain material and coherent feedback of the emitted light. In normal lasers feedback is provided by placing the gain material between mirrors – i.e. inside a cavity. Now, could we accomplish such feedback by keeping photons that have just been emitted from an active laser medium, simply from propagating away? Light is normally the fastest ‘object’ in the universe, but researchers have, indeed, recently conceived ways of slowing it down considerably, even long enough to consider it as having been stopped altogether. In the lecture, I will explain how these two fascinating aspects of light – lasing and stopped light – can be brought together in a tiny nanoplasmonic waveguide (with dimensions much smaller than the wavelength of the emitted light itself) to form the basis for a novel concept of a laser that no longer requires a cavity for feedback and can be realized on the nano-scale: A stopped-light laser. I will deliberate on how this is possible by creating stopped-light singularities in the optical density of states that function in ways similar to an optical black hole and discus the complex spatio-temporal interaction between plasmons, light and nonlinear gain media on the nanoscale and at ultrafast time-scales. The lecture will provide an outlook, charting new opportunities of cavity-free lasers for integration on the nanoscale, ultrafast broadband signalling and in exotic environments such as synthetic tissue. --------- CUPS - Cambridge University Physics Society We are a student-run university society organising scientific talks and other events for our members and public.
