Johns Hopkins Kimmel Cancer Center scientists have found that interferon, used for 30 years to treat blood cancers, multiple sclerosis and hepatitis, selectively kills colon cancer cells when combined with another standard chemotherapy agent. New studies in cell lines suggest that the combination tactic, which targets a common gene pathway in colon cancer cells, could be more potent than either drug alone, and has fewer side effects.
"Instead of killing a tree by chopping it down, this approach focuses on cutting off the diseased branch, leaving the rest of the tree relatively unscathed," says Betsy Barnes, Ph.D., assistant professor of oncology and lead researcher.
By itself, interferons cell-killing activity is non-specific in targeting a variety of cells and cell-based gene activity, causing serious side effects such as heart failure and low blood counts, in addition to killing cancer cells. But in an August 15 issue of Cancer Research, the Kimmel Cancer Center scientists found one factor in interferons makeup that could have cancer-killing qualities, but with fewer side effects since it activates fewer genes.

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...
