US fertility experts have discovered a potential new role for the wonder drug tamoxifen – helping breast cancer patients to have babies by IVF.
In a study published in Europes leading reproductive medicine journal Human Reproduction, researchers from New Yorks Cornell University report the first IVF pregnancy to result from the use of tamoxifen as an ovarian stimulant.
In a study of 12 breast cancer survivors they found that stimulating the ovaries with a short, carefully timed course of tamoxifen boosted the number of eggs they could retrieve. Every patient had one or more embryos either for freezing for later attempts at pregnancy, or for immediate transfer. One patient who had two fresh embryos transferred has already given birth to twins. Another patient conceived on her second attempt although she miscarried. None of the patients with frozen embryos has yet attempted pregnancy.

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...
