Dangers for winemaking

21.05.2017

James Daniell (James E. Daniel) of the Karlsruhe Institute of Technology and his colleagues in the German-Australian research team have developed the first "risk index" of natural hazards for more than 7000 wine regions around the world. At the top of the list are Argentina, Georgia and Moldova, while French Polynesia, Sri Lanka and the Netherlands Antilles are still safe. The scientists presented their results at a meeting of the European Geophysical Union and briefly in a publication in Geophysical Research Abstracts. In addition, the group developed the Wineisk website, which is now more practical.

Natural phenomena are causing more and more damage to winemaking around the world. The hail that so suffers, for example, in Burgundy, is but one disaster among many. Floods, frosts and fires are increasingly common in wine regions, thanks in part to the changing global climate. Meteorologists, geophysicists and economists have collaborated to develop a first-of-its-kind "risk index" based on natural hazards for more than 7000 wine regions around the world.

The team of scientists collected maps of climate-related and non-climate hazards and integrated the data to calculate an overall risk index. At the same time, 50 points were considered low, and 200 points were considered very high. This list was headed by Argentina, Georgia and Moldova, the least at risk were French Polynesia, Sri Lanka and the Netherlands Antilles. The researchers concluded that although all risks cannot be avoided, winemakers can reduce them by installing, for example, sprinklers in their vineyards to protect against frost.

In general, the study can be useful not only for the wine industry, but also for insurance companies and governments, but also for non-professional drinkers. Knowing the fate of your favorite brand and being able to protect your collections from earthquakes and other dangers - for example, by securing expensive bottles on racks using rubber cords - is worth something.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Dove visual memory 12.04.2007

Employees of the Mediterranean Institute of Cognitive Neuroscience in Marseille (France) studied the visual memory of pigeons.

By showing birds hundreds of images and teaching them to peck at a certain button if the picture is already familiar, psychologists have found that a pigeon's visual memory can store up to 1200 images. Given the very small size of the brain of a pigeon, this is very good. For example, baboons are able to memorize up to 6000 images.

What explains such a good visual memory of pigeons is not yet clear, but it is assumed that it helps birds in navigation.
