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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
