The first new oral drug in 50 years to prevent blood clots after knee-replacement surgery was superior to the standard treatment in a clinical trial of about 2,300 patients led by the University of Rochester Medical Center.
Researchers also have tested the new drug, ximelagatran, for prevention of stroke, heart attacks and deep vein thrombosis, and if approved by the FDA it would offer millions of patients an alternative to the commonly prescribed anticoagulant, warfarin.
Results of the UR study are reported in the Oct. 30, 2003, New England Journal of Medicine, which in this issue paid special attention to scientific advances in the treatment of blood clots, or thrombosis. Two other major clinical trials also are reported.

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...
