Cambridge University scientists announced a way of making long thin carbon nanotubes link together to form a material that might suffice to built a space elevator.
Last September we wrote that one insurer would “no longer insure against bodily injury, property damage, or personal and advertising injury related to the actual, alleged, or threatened presence of or exposure to nanotubes or nanotechnology in any form.” Now Christine Peterson passes along this item from Rhitu Chatterjee writing in the American Chemical Society… Continue reading Insurance industry looking for more data on nanotechnology risks
In light of the call for open-source sensing arising from nanotech-based environmental monitoring, it is interesting to note this recent progress in building a nanotech-powered biosensor powered by molecular motors.
An international team of investigators has demonstrated in mice a nanotech method of orally delivering an anticancer therapy that would normally have to be delivered by injection.
The Project on Emerging Nanotechnologies, via AAAS EurekAlert, brings us an update on federal efforts to address the potential environmental, health and safety (EHS) risks posed by engineered nanomaterials. “New House bill addresses need for more risk research, oversight“: The House Science and Technology Committee [on January 15] introduced legislation that highlights the growing attention… Continue reading Nanotechnology oversight issues moving forward in Congress
Having demonstrated a year ago an effective nanotech method for shutting down specific gene expression in a mouse model of colitis, a team of researchers at Tel Aviv University is preparing to test this method in clinical trials for blood, pancreatic, breast and brain cancers.
A method that eliminates metallic single walled carbon nanotubes from mixtures leaving fully functional semiconducting SWCNTs may open the way for various nanotech applications that require pure semiconducting SWCNTs.
From the February 2009 issue of the “science is culture” publication Seed magazine, not yet online: Hypothesis: Civil Nanotechnology Starting in 2009, nanotech-based sensing will enable a level of environmental monitoring that could help reduce pollution tremendously. Such devices could be of immense benefit to the environment, but unfortunately, without careful attention they will trigger… Continue reading Civil nanotechnology: Open source sensing in Seed magazine
The January issue of Life Extension Magazine offers a report on the eventual promise of medical nanobots.
The ribosome has a previously unsuspected method of error correction—in this case monitoring the fidelity of protein synthesis after the peptide bond is formed.
