In the battle against cancer, Virginia Tech researchers have developed a potential warhead to better kill cancer cells, a new missile to deliver the warhead more efficiently to the diseased areas, and a new detonation device once the warhead is in place.
In a cross-disciplinary effort, the researchers, using photodynamic therapy (PDT), have obtained results in three different areas that, used together, have the possibility of providing more efficient, less invasive, and more specific treatments for cancer and other diseases such as age-related macular-degeneration.
A long-term concept has held that one should be able to use light-activated compounds to kill diseased cells, said Karen Brewer, associate professor of chemistry. The researchers have developed new tri-metallic supra-molecules that can be positioned in exact parts of cancer cells and excited by a therapeutic wavelength at which light propagates efficiently through tissue. Only when the light hits the supra-molecules do they become toxic to the cancer cells.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
