Magnetically assembled Nanotube-Tipped Probe Developed

Improved cell by cell analysis is made possible as well as injecting drugs into active cells one at time. This development could be combined with improved versions of surgical microbots to achieve something very similar to the vision of nanobot cellular repair nanomedicine. Drexel University College of Engineering researchers have successfully developed carbon nanotube-tipped pipettes …

MIT Technology Review Geordie Rose Interview

MIT Technology Review Jason Pontin (JP) interviews Geordie Rose (GR) of Dwave Systems about the Quantum computer The interview gets more interesting around page 4. The first three screens review the old controversy, which will be irrelevant based on targets being hit in 2008. JP: The plan is to demonstrate a 1,024-qubit machine in 2008? …

Solar powered Fleabots created

An autonomous robotic flea has been developed that is capable of jumping nearly 30 times its height, thanks to what is arguably the world’s smallest rubber band. Tiny micro electromechanical systems (MEMS) motors stretch a diminutive nine-micron-thick, two-millimeter-long rubber band in order to allow a microbot to catapult itself through the air like a flea. …

Native protein nanolithography to work with fragile proteins

From Nanowerk a spotlight report on native protein nanolithography (NPNL) that allows the fabrication of bioactive protein nanoarrays down to a resolution of 50 nm in a fast and versatile manner without the need of vacuum or ambient atmosphere conditions – but under conditions of a physiological solution. This allow for nanopatterning of more fragile …

Stem Cell breakthrough regrows Heart Valve

British scientists say they have succeeded in growing part of a human heart from stem cells in a medical research first with far-reaching implications. The researchers say it could mean replacement tissue for transplants could become available as quickly as three years, The (London) Guardian reported Monday. Reaching that level, however, will depend on the …

Exponential production and nanofactories

Exponential manufacturing is one of the key features that magnifies the impact of molecular nanotechnology Exponential manufacturing is a nanofactory being able to produce another nanofactory. Nanofactories with this capability can double their number in the time it takes to make another copy. When would exponential manufacturing dominate over projected conventional production ? A nanofactory …

Nasa Institute of Advanced Concepts may be shutdown by August, 2007

NASA will likely shut down its Institute for Advanced Concepts, which funds research into futuristic ideas in spaceflight and aeronautics in August 2007 unless there is budgetary change. I hope they do not shutdown the NIAC because it is doing fantastic work. Brian WangBrian Wang is a Futurist Thought Leader and a popular Science blogger …

1-nanometer resolution is NSF CAREER researcher’s goal for optical imaging

Success on this project would make it far cheaper and easier to see and work at near-molecular nanotech levels. “The resolution of most optical microscopes is restricted by the so-called ‘diffraction limit,’ which means we cannot produce optical images with resolutions higher than a few hundred nanometers,” Xu said. “Currently, the most advanced optical microscope …

Costs of regulations

An interesting article about the costs of regulation by Eliezer Yudkowsky It links to the benefits of FDA regulation relative to that in foreign countries could reasonably be put at some 5,000 casualties per decade or 10,000 per decade for worst-case scenarios. In comparison, it has been argued above that the cost of FDA delay …

Could crazy technology save the planet?

Crazy-sounding ideas for saving the planet are getting a serious look from top scientists, a sign of their fears about global warming and the desire for an insurance policy in case things get worse. There’s the man-made “volcano” that shoots gigatons of sulfur high into the air. The space “sun shade” made of trillions of …

Other uses for metamaterials

Making a negative-index material that works for visible light is more difficult, because the building blocks have to be much smaller–no bigger than 10 to 20 nanometers. That’s now very possible to achieve, however, and several groups are working on it. If it can be done, these metamaterials could be used to increase the amount …
