Adding stereotactic radiosurgery – which entails delivering radiation to specific points in the brain while sparing normal tissue – after whole brain radiation therapy helps certain patients with cancer that has spread to the brain live longer, says a new study by researchers at Thomas Jefferson University Hospital in Philadelphia.
In as many as one-third of all patients with lung and breast cancers, the disease spreads, or metastasizes, to the brain, leaving few good options. The disease causes neurological problems, and many patients live only about four months. Chemotherapy has been relatively ineffective in shrinking tumors and improving quality of life.
Between 1996 and 2001, the Radiation Therapy Oncology Group (RTOG), a federally funded clinical trials group, led by researchers at Jefferson Medical College and elsewhere randomly assigned 333 patients to receive either the standard whole brain radiation therapy alone, or whole brain radiation therapy followed by stereotactic radiosurgery.

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...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

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...
