Researchers studying plant behaviour have discovered similarities between the processes preventing plants from wilting and humans from suffering impotence. Data recently published by the University of the West of England shows the same chemical chain of events is involved in both situations - and has led to an understanding of how water loss from plants might be reduced.
This blocking action has parallels with the chemical effect of impotence treatments in humans. Plants lose water through their stomata, small pores surrounded by guard cells, that cover the leaves. The signals governing the opening and closing of a plant`s stomata are closely allied to the way human blood vessels contract and relax to control blood flow.
The key finding of the research concerns the role played by nitric oxide in the closure of the plant`s stomata. Researchers from UWE`s Faculty of Applied Sciences demonstrated this in a series of experiments in which chemicals to `scavenge` nitric oxide or inhibit its action were added. The reaction of the cells could be clearly measured under the microscope. In other tests, fluorescent dyes that react to the presence of nitric oxide were added to show the effect of different `scavengers` on the guard cells under a special confocal microscope.

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.
