A new study finds men treated with hormone therapy for prostate cancer may experience temporary cognitive changes that can affect verbal fluency, visual recognition and visual memory. The study, published in the April 1, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, finds the degree of cognitive dysfunction appeared to be related to a decline in serum estradiol brought on by hormonal treatment.
Androgen-deprivation therapy (AD) is an effective adjuvant therapy in the treatment of prostate cancer. It effectively reduces levels of testosterone, which acts as a tumor stimulant, and estradiol, a form of estrogen in men. Testosterone and estradiol are known to be important in neurological development and play a particularly important role in the cognitive areas of learning and memory. Previous studies in women have shown declining estradiol levels to effect cognition but until now little data existed in men.
Eeva Salminen, M.D. and colleagues at Turku University Hospital in Turku, Finland investigated the relationship between serum estradiol and cognitive functioning in men with prostate cancer treated with androgen-deprivation therapy.

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...
