Researchers from St. Petersburg have invented a way to check the viability of grains and seeds of agricultural plants without prior germination. The scientists assume that injuries of the germ and tissues of seeds can be revealed through X-ray photomicrography with the help of computer recognition system. This methodology allows determining the quality of wheat, barley, oats, rye and other crops seed grain.
The yield of agricultural cultures depends on viability and quality of seed grain. Researchers from the Agrophysical Research Institute, Russian Agricultural Academy (St. Petersburg) M.V. Arkhipov, L.P. Gusakova and D. I. Alekseyeva have developed a computer system to reveal nonviable and defective grains and seeds without prior germination.
The X-rays photograph is taken of seeds or grain. The photographs show the breaks of integrity of the corn seed storage tissue and defects of the germ. They can be caused by different reasons - mechanical load while transporting and storage, bacterial or mycosis infection, or vermin. The seeds often perish because of losing the germ - the germ can be knocked out in harvesting or can be eaten out by insects. The researchers have made reference images of each defect to compare X-ray photographs of the seeds with them.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

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...
