Inhibiting the growth and the angiogenic properties of cancer is an important modality for cancer treatment and research. Angiogenesis, the development of new blood vessels from pre-existing vasculature, supports the development of many diseases including cancer, rheumatoid arthritis and others. In the case of cancer, angiogenesis is essential for the growth, progression and metastasis of a tumor and thus, agents that inhibit angiogenesis are attractive therapeutic options.
In an article published today in the April issue of Cancer Cell (Vol. 3, No. 4, pg. 363), Winship Cancer Institute (WCI) researchers report that 2-methoxyestradiol (2ME2) inhibits tumor growth and angiogenesis by suppressing hypoxia-inducible factor-1 (HIF). HIF is a factor that is over-expressed in more than 70% of human cancers and their metastases, including breast, prostate, brain, lung, and head and neck cancers.
Besides cancer, HIF is also associated with diseases of the bone and diseases that are mediated by inflammation such as rheumatoid arthritis.

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...
