Seed implants have become a widely-accepted treatment option for early stage prostate cancer because it is very effective at curing the cancer, is minimally invasive and often spares patients from side effects of other treatments, such as impotence and incontinence. The seeds, similar in size to a grain of rice, contain a radiation dose that, once implanted, delivers concentrated radiation to the prostate, sparing surrounding organs and tissue.
Doctors in this study evaluated the long-term results of permanent seed implants in men with early stage prostate cancer. Nearly 2,700 men were studied at 11 institutions in the United States over eight years. The radioactive seeds were administered with the aid of ultrasound-guided techniques to accurately place the seeds in the prostate gland. The patients received the seed implants as the sole treatment for prostate cancer with no additional chemotherapy or radiation therapy.
"This study is exciting because it shows that brachytherapy alone without additional surgery, radiation or drugs can be effective at curing early-stage prostate cancer," said Michael J. Zelefsky, M.D., lead author of the study and Chief of Brachytherapy Services at Memorial Sloan-Kettering Cancer Center in New York. "These results also confirm other findings that the quality of the seed implant is a critical ingredient for achieving a better outcome."

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
