FDA advisors declare 'FDA science and mission at risk'

The nation's public health is at risk, as are the regulatory systems that oversee the nation's drug and device supplies, according to an FDA Science Board report being presented at a House Energy and Commerce Committee hearing today. The committee attributed the deficiencies to soaring demands on the FDA; and resources that have not increased in proportion to those demands.

New nanotube findings give boost to potential biomedical applications

Carbon nanotubes-cylinders are packed with the potential to be highly accurate vehicles for administering medicines and other therapeutic agents to patients. But a dearth of data about what happens to the tubes after they discharge their medical payloads has been a major stumbling block to progress. Now, Stanford researchers, who spent months tracking the tiny tubes inside mice, have found some answers.

Fuel-cell cars race to reality

For those who dream of a cleaner, greener future thanks to nonpolluting technologies, recent auto shows have showcased some ideas. The biggest conglomeration was at the December 2006 Los Angeles Auto Show, where green machines were a dominant theme. The January Detroit auto show was more low-key on the green front, but there were a couple of intriguing, well-developed concepts on display there as well.

Call for scientific data on applications of nanotechnology and nanomaterials used in food and feed

The European Commission has requested an initial scientific opinion from the European Food Safety Authority (EFSA) relating to the risks arising from nanoscience and nanotechnologies on food and feed safety and the environment. The request also asks to identify the nature of the possible hazards associated with actual and foreseen applications in the food and feed area and to provide general guidance on data needed for the risk assessment of such technologies and applications.
