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.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
