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.

A Swedish-German team of researchers has cleared up a key process for the artificial production of silk. With the help of the intense X-rays from DESY's...
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
