Experiments with liposomes – cell-like "water balloons" composed of artificially created phospholipid bilayers similar to natural cell membranes – have revealed unexpected behavior in the presence of electrical fields that may provide a paradigm-shifting change in sciences understanding of biomembrane function in operating living systems.
Arizona State University chemists Mark Hayes and Michele Pysher have found that liposomes have a tendency to form tube-like extensions in their membranes through the influence of local electrical fields. In particular, the surprising finding of such electrically caused bionanotubule formation may reveal a previously unknown process involved in the development of structures like axons and dendrites in nerve cells.
Hayes will present the results of the experiments at a 2 p.m. March 15 session entitled "Colloids in Complex Fluids" at the American Chemical Society meeting in San Diego.

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...
