In working to halt the overgrowth of blood vessels that feed cancerous tumors, the antiangiogenic molecules endostatin and tumstatin take two distinct and very different tactics, according to a study in the April 15 issue of the Proceedings of the National Academy of Sciences (PNAS).
These findings, which currently appear on-line, suggest for the first time that these two agents combined may prove more effective in battling cancer than either one used separately.
"Just as aspirin, acetaminophen and ibuprofen each work in different ways to relieve pain, it now appears that endogenous inhibitors like endostatin and tumstatin work in different ways to halt angiogenesis," explains the studys senior author Raghu Kalluri, Ph.D., of the Center for Matrix Biology at Beth Israel Deaconess Medical Center (BIDMC). "These findings may help us to be more informed in the ways we use these molecules as potential drug candidates in the future."

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...
