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.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
