Research has shown that the drug tamoxifen citrate not only helps prevent recurrence of breast cancer, but it also can keep the deadly disease from occurring in the first place in some women.
But a new University of North Carolina at Chapel Hill study indicates its unlikely that tamoxifen will ever be given widely to women to prevent breast cancer. Thats because the drug would avert only a maximum of 6 percent to 8.3 percent of breast tumors in eligible women, UNC School of Medicine researchers have found. "Our calculations showed that tamoxifens possibly harmful side effects, including blood clots and stroke, would rule out some 90 percent of women who might benefit from taking it each day," said Dr. Russell P Harris, associate professor of medicine at UNC. A report on the study appears in the latest issue of the Archives of Internal Medicine.
Besides Harris, a member of UNCs Lineberger Comprehensive Cancer Center, authors are principal investigator Dr. Carmen L. Lewis, assistant professor of medicine at UNC; Dr. Linda S. Kinsinger, assistant director of the VA Center for Health Promotion and Disease Prevention; and Robert J. Schwartz, a computer programmer at UNCs Cecil G. Sheps Center for Health Services Research.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
