Rochester expert warns of toxicity in new wave of science
Nanotechnology, a science devoted to engineering things that are unimaginably small, may pose a health hazard and should be investigated further, warns a University of Rochester scientist and worldwide expert in the field, who received a $5.5 million grant to conduct such research.
Günter Oberdörster, Ph.D., professor of Toxicology in Environmental Medicine and director of the universitys EPA Particulate Matter Center, has already completed one study showing that inhaled nano-sized particles accumulate in the nasal cavities, lungs and brains of rats. Scientists speculate this buildup could lead to harmful inflammation and the risk of brain damage or central nervous system disorders. Oberdörsters study is scheduled to appear in the May 2004 journal Inhalation Toxicology, and is receiving widespread attention in the scientific community; it was cited at an international nanotechnology/health conference earlier this year in England by the Institute of Physics.

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
