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.

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...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
