A new long-term study finds over 20 years, only one in five women who have mammograms every two years will have to undergo follow up evaluation for a false positive finding. Only one in 16 will have an unnecessary invasive procedure over two decades. The study, published August 23, 2004 in the online edition of CANCER, a peer-reviewed journal of the American Cancer Society, should reassure physicians and patients that the risks of breast cancer screening are minimal given the notable benefit of breast cancer screening. The abstract of this article will be freely accessible via the CANCER Newsroom upon online publication.
Breast cancer screening by regular screening mammography has a proven benefit to saving lives. However, false positives and subsequent recall for follow up evaluation create significant psychosocial distress.
The extent of false positive recall is unclear. Previous studies have claimed the cumulative risk of a high false positive recall over the years was significant. However, the estimates and conclusions made to date are weakened by flawed study designs.

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...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
