While biomedical devices such as prosthetic heart valves, heart-assist devices, oxygenators, vascular grafts and hemodialysis systems can help to save or significantly extend lives, these same devices also can damage the blood cells which travel through them. Severe consequences can result when blood cells are damaged or broken down, said Marina Kameneva, Ph.D., research associate professor of surgery at the University of Pittsburgh School of Medicine.
Dr. Kameneva will discuss the issue in a plenary lecture on "hemorheological aspects of flow induced blood trauma in artificial organs" on Sept. 26 during a joint meeting of the 11th International Congress of Biorheology and the 4th International Conference on Clinical Hemorheology in Antalya, Turkey. Rheology is the science of the deformation and flow of matter.
"Biomedical devices are widely used to repair or replace a number of cardiovascular system elements," said Dr. Kameneva, a scientist at the University of Pittsburghs McGowan Institute for Regenerative Medicine who is one of the few working worldwide whose research focuses on fluid dynamics and artificial blood products. "The successful functioning of these devices strongly depends on the way they disturb blood."

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...
