Scheme to Let Robot Take Over Brain-Computer Interface

In Bionic, Cogno, Disabled People, Enhancement, Governance, Health, Information Technology, nano, Nanoscale, NBICS, Neuro, Robotics on May 23, 2008 at 2:26 am

20 May 2008—A group of mechanical engineers at Caltech have come up with a way to guide miniature robots in the task of inserting and positioning electrode arrays in brain tissue. What they propose would be the first robotic approach to establishing an interface between computers and the brain by positioning electrodes in neural tissue.

Carbon nanotubes introduced into the abdominal cavity of mice show asbestos-like pathogenicity in a pilot study

Abstract

Carbon nanotubes1 have distinctive characteristics2, but their needle-like fibre shape has been compared to asbestos3, raising concerns that widespread use of carbon nanotubes may lead to mesothelioma, cancer of the lining of the lungs caused by exposure to asbestos4. Here we show that exposing the mesothelial lining of the body cavity of mice, as a surrogate for the mesothelial lining of the chest cavity, to long multiwalled carbon nanotubes results in asbestos-like, length-dependent, pathogenic behaviour. This includes inflammation and the formation of lesions known as granulomas. This is of considerable importance, because research and business communities continue to invest heavily in carbon nanotubes for a wide range of products5 under the assumption that they are no more hazardous than graphite. Our results suggest the need for further research and great caution before introducing such products into the market if long-term harm is to be avoided.

Armed Forces Institute of Regenerative Medicine created

In Health, Stem Cell on May 19, 2008 at 1:30 pm

the Department of Defense announced the creation of the Armed Forces Institute of Regenerative Medicine, which will go by the happy acronym AFIRM. According to DOD’s news service, AFIRM will “harness stem cell research and technology … to reconstruct new skin, muscles and tendons, and even ears, noses and fingers.” The government is budgeting $250 million in public and private money for the project’s first five years. NIH and three universities will be on the team.

Abstract:

BACKGROUND: Airborne nanoparticles from vehicle emissions have been associated with adverse effects in people with pulmonary and cardiovascular disease, and toxicological studies have shown that nanoparticles can be more hazardous than their larger scale counterparts. Re-circulating air filtration in automobiles and houses may provide a low-cost solution to reducing exposures in many cases, thus reducing possible health risks.

OBJECTIVES: We investigated the effectiveness of re-circulating air filtration on reducing exposure to incidental and intentionally produced airborne nanoparticles under two scenarios: while driving in traffic, and while generating nanomaterials using gas phase synthesis.

METHODS: We tested the re-circulating air filtration in two commercial vehicles when driving in traffic, as well as in a non-ventilation room with a nanoparticle generator, simulating a nanomaterial production facility. We also measured the time-resolved aerosol size distribution during the in-car recirculation to investigate how re-circulating air filtration impacts on particles of different sizes. A recirculation model was developed to describe the aerosol concentration change during recirculation.

RESULTS: The use of inexpensive low-efficiency filters in recirculation systems is shown to reduce nanoparticle concentrations to below levels found in a typical office within three minutes while driving through heavy traffic, and within twenty minutes in a simulated nanomaterial production facility.

CONCLUSIONS: Development and application of this technology could lead to significant reductions in airborne nanoparticle exposure, reducing possible risks to health and providing solutions to generating nanomaterials safely.

Abstract

Nanotechnology presents countless opportunities to develop new and improved consumer products for the benefit of society. However, as the industrial production and use of nanotechnology products continue to expand at a fast scale, potential human health concerns and ecological safeguards for the environment need to be addressed. Health risk assessment involving different animal species for multi-organ toxicity complimented with molecular investigations in cells is essential for investigating the potential toxic effects of nanomaterials. The purpose of this review is to present the current state of knowledge regarding the potential routes of human exposure to nanomaterials and their biological health effects. Although anthropogenic nanosized particles emitted in the environment are known to produce adverse human health in susceptible populations, much remains to be explored. Exposures can occur from direct exposure or from the use of commercial products made of nanomaterials. Safe manufacturing guidelines for prevention of exposures and recommendations on safe handling and use need to be established on a proactive basis to prevent adverse outcomes.
