Blade Runner: What Does It Mean to Be Human in a Artificial World? - 0 views

  •  
    "In our strange and potentially very dangerous world where science fiction and Charles Darwin often collide, a handful of scientists are racing to be the first to create life. According to a flood of recent reports, this artificial life could be as close as six months away. "

New iPhone apps aim to enhance education (eSchool News) - 1 views

  •  
    Flash-card programs, eBook reading software, and science and math simulations are among more than a dozen educational software programs developed for Apple's iPhone that appear in the new App Store, which debuted July 11. Educators and students can use these applications to locate stars and constellations, visualize a hydrogen atom, learn a new language, and read books on their iPhone, among other uses.

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."

What We do not know ( Infographic ) - 10 views

  •  
    "When it comes to history, science, and global affairs. Americans are notoriously uninformed. Too many of us shrug off our inability to" do math" or speak a second language. And in effect, we assume that these capacities are somehow dispensable, however they are not. Higher education in America is experiencing a similar misassumption......."

2 | When The Internet Is Your Brain: - 8 views

  •  
    In H+: The Digital Series, a post-apocalyptic techno-thriller that debuts today from producer Bryan Singer (The Usual Suspects, X2, House), a consumer device that allows people to stay connected 24-hours a day directly results in the demise of one-third of the Earth's population. That's a scary vision for any epoch, but perhaps especially one currently salivating at the prospect of new iThings. The culprit in H+, which is shorthand for a real-world movement called transhumanism, is a wonder chip that we implant in our brains, thereby eliminating the need to hunch over physical electronics forever. But the price paid for this technological leap is a steep--when a global virus strikes the implants, the system failure is fatal.

Project Based Learning Viewed Through a Digital Lens - 17 views

  •  
    Often we search for meaningful ways to integrate digital technology in project based learning activities given to our students. We also would like our students to develop a thorough understanding of the concepts underlying the work - after all this is the purpose of the project. Giving students the opportunity to complete and present their project through a digital lens has one great advantage - student engagement. This in turn causes students to develop a more in depth understanding of concepts.

How to Create Screencasts for Teaching and Learning Using Jing - 25 views

  •  
    Have you ever wanted to create short "how to" video for your students to use for homework, remembering facts, and solving math problems. How often have your students stated, "I could not complete the homework assignment, because I could not remember the steps and no one could help me." Well the answer is to create a screencast or video for posting on your class wiki or blog for students to view at home or anywhere else they have web access.
