Researchers have discovered a fascinating symbiotic relationship between a wasp species and a newly discovered bacterial species – a relationship that potentially sheds light on how bacteria can be successfully utilized by higher organisms in defensive mechanisms against other microbes. In the new work, researchers show that a solitary ground-nesting wasp, the European beewolf, harbors Streptomyces bacteria in unique structures within its antennae and that females utilize these bacterial symbionts to protect the wasp larvae against pathogenic fungi.
Detrimental microorganisms are a permanent threat to higher organisms, and because of their high reproductive potential and adaptability, they are extremely difficult to control. Ironically, the best counteragents against microbes are often other microbes that produce very potent antibiotics. Thus, an effective and elegant way to counter the threat caused by bacteria and fungi is to establish a symbiotic relationship with innocuous antibiotic-producing bacteria that provide protection against the most dangerous pathogens. As yet, only a few cases of defensive symbioses between higher organisms and bacteria have been reported.
In their new paper, Martin Kaltenpoth and his colleagues at the Biocenter of the University of Würzburg show that the European beewolf Philanthus triangulum has evolved a defensive symbiosis with a new species of bacteria of the genus Streptomyces. Interestingly, this genus comprises the most important group of bacteria for the production of antibiotics for human medicine.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
