COLUMBIA, Md., April 14 /PRNewswire-USNewswire/ -- The Universities Space Research Association (USRA) is extremely proud to welcome the University of Stuttgart to its distinguished group of member universities.

Researchers discover why atoms in solids show a preference for certain structures.

Since several years members of the Research Group Baubotanik at the Institute of Theory of Modern Architecture and Design (University of Stuttgart) are focussing on the idea of living plant constructions. Recently the first “baubotanical” tower made of living trees has been completed.

German-led scientists say they have observed for the first time a rare molecule, the existence of which has until now only been predicted by theory. The researchers from the University of Stuttgart and the University of Oklahoma told the BBC the so-called Rydberg molecule was theorized to form when one of its two atoms has an electron orbiting at an extreme distance from the atom's nucleus. First predicted by physicist Chris Greene of the University of Colorado, the existence of the Rydberg molecule is consistent with quantum theories proposed in 1934 by Nobel prize-winning physicist Enrico Fermi, the researchers said. The scientists said they observed a Rydberg molecule by super-cooling rubidium molecules to a temperature near absolute zero -- minus 273 degrees Celsius. We use an ultracold cloud of rubidium -- as you cool it, the atoms in the gas move closer together, Professor Vera Bendkowsky, who led the study at the University of Stuttgart, told the BBC.
