Using transparent zebrafish embryos, researchers at Jefferson Medical College in Philadelphia have shown that a microscopic nanoparticle can help fend off damage to normal tissue from radiation. The nanoparticle, a soccer ball-shaped, hollow, carbon-based structure known as a fullerene, acts like an "oxygen sink," binding to dangerous oxygen radicals produced by radiation.
The scientists, led by Adam P. Dicker, M.D., Ph.D., and Ulrich Rodeck, M.D., see fullerenes as a potentially "new class of radioprotective agents." Dr. Dicker, recently appointed Vice-Chair for Translational Research of the Radiation Therapy Oncology Group, is associate professor of radiation oncology at Jefferson Medical College of Thomas Jefferson University and at the Kimmel Cancer Center at Jefferson. Dr. Rodeck is professor of dermatology at Jefferson Medical College. They will present their teams results April 5, 2006 at the annual meeting of American Association for Cancer Research in Washington, D.C.
While chemotherapy and radiotherapy are the standard treatments for cancer, they take their respective toll on the body. Radiation can damage epithelial cells and lead to permanent hair loss, among other effects, and certain types of systemic chemotherapy can produce hearing loss and damage to a number of organs, including the heart and kidneys. Some other side effects include esophagitis, diarrhea, and mouth and intestinal ulcers.

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.
