Medical devices powered by the ear itself - MIT News Office - 1 views

  • Health Sciences and Technology (HST) demonstrate for the first time that this battery could power implantable electronic devices without impairing hearing.
  • The devices could monitor biological activity in the ears of people with hearing or balance impairments, or responses to therapies. Eventually, they might even deliver therapies themselves
  • “In the past, people have thought that the space where the high potential is located is inaccessible for implantable devices, because potentially it’s very dangerous if you encroach on it,” Stankovic says. “We have known for 60 years that this battery exists and that it’s really important for normal hearing, but nobody has attempted to use this battery to power useful electronics.”

  • The ear converts a mechanical force — the vibration of the eardrum — into an electrochemical signal that can be processed by the brain; the biological battery is the source of that signal’s current. Located in the part of the ear called the cochlea, the battery chamber is divided by a membrane, some of whose cells are specialized to pump ions. An imbalance of potassium and sodium ions on opposite sides of the membrane, together with the particular arrangement of the pumps, creates an electrical voltage.
  • Low-power chips, however, are precisely the area of expertise of Anantha Chandrakasan’s group at MTL
  • The frequency of the signal was thus itself an indication of the electrochemical properties of the inner ear.
  • in cochlear implants, diagnostics and implantable hearing aids. “The fact that you can generate the power for a low voltage from the cochlea itself raises the possibility of using that as a power source to drive a cochlear implant,” Megerian says. “Imagine if we were able to measure that voltage in various disease states. There would potentially be a diagnostic algorithm for aberrations in that electrical output.”
  • “I’m not ready to say that the present iteration of this technology is ready,” Megerian cautions. But he adds that, “If we could tap into the natural power source of the cochlea, it could potentially be a driver behind the amplification technology of the future.”
  •  
    "For the first time, researchers power an implantable electronic device using an electrical potential - a natural battery - deep in the inner ear."
  •  
    "All of D-Lab's classes assess the needs of people in less-privileged communities around the world, examining innovations in technology, education or communications that might address those needs. The classes then seek ways to spread word of these solutions - and in some cases, to spur the creation of organizations to help disseminate them. Specific projects have focused on improved wheelchairs and prosthetics; water and sanitation systems; and recycling waste to produce useful products, including charcoal fuel made from agricultural waste."

Wolfram|Alpha: a new way to find data online? - SciTechBlog - CNN.com Blogs - 0 views

  •  
    Say you're an investor and you want to see how two companies are faring against each other on the market. You could type in "IBM versus Apple" and Wolfram|Alpha will generate graphs and tables to compare the stocks over time. It also give you the Web-based sources used to generate the data, so you know where the numbers are coming from. The site also solves equations and shows the steps it took to do so, which will be of interest to high school students and math majors. Not into number crunching? If you live near the coast, you could type in "tides in ____" and find charts of tidal and lunar information. You could also graph that against other cities, which would be cool if you're a surfer. The site is also interesting for academic queries. Type in "Internet users in Africa" and you'll get the total number of Web users there - 51 million - as well as lists of the number of users by country plus graphs of this information. If you're in the fisheries business, or if you're an environmentalist, you could type in "fish produced in Italy versus France" to get an idea of how that sector is faring. The answer includes specifics, like how much of the fish crop was farmed versus what was captured. Such data could be used to argue policy points or to debate whether or not certain industries are sustainable.

Twitter Your Lesson Plans » TeachEng.us - 0 views

  •  
    How about a quick lesson plan? How abouttwitter.png a way to keep a shorthand record of daily class activities? Then how about twitter? Start a Twitter profile (a separate one just for teaching, so not to annoy your friends), and at the end of each class day jot down what you did in class (see below for my Monday, Feb. 11th). Networking with other subject area teachers will encourage collaboration on similar lessons. And possibly (though we teachers would hope not in a 1984 kind of way), an administrator could link in and keep tabs. If I were a curriculum person in an administration, the first thing I would do would be to set up accounts for each teacher to post one daily update.

To Shred, or Not To Shred... by Bob Sprankle - 0 views

  •  
    "One of the main reasons I started using Blogs with students was so their work had permanence, and wasn't just shoved in a box in the back of an attic, but published in an authentic venue, where people could continue to interact with it. For years to come. I still have people leaving comments on the first Blog that I set up for students over 5 years ago. It remains a living, breathing organism. The students can still go back and see their previous work."
