Where do fish live that like to walk on the bottom instead of swimming?

In 2010, new species of anglerfish were found off the coast of Australia. Instead of swimming, these fish prefer to “walk” along the bottom, moving their pectoral fins, which look like animal paws.

What is a weevil?

Around us, without stopping, there is a constant war between man and insects. Some insects are just parasites that spread infection, and some are in the business of destroying what a person is trying to grow. If there is any family of insects that humanity can do without, then these are weevils (they are also called elephants).

Despite the fact that weevils represent only a subclass of insects, their family is the most numerous in the animal kingdom with more than 35 species, and, apparently, most species of weevils have not yet been discovered and described by scientists!

Weevils vary greatly in shape, size and color. Usually these small insects are easily recognizable by their proboscis-like or knife-blade protrusions on their heads. At the end of these protrusions is the mouth. The females use their proboscises to drill holes into which eggs will be laid. Elephant larvae usually look like fat white worms and, like adults, eat various plants with a good appetite.

Weevils are considered so harmful not because of exorbitant appetite or large numbers of individuals in the colony. The thing is that they damage the vital and most delicate parts of plants: buds, fruits, seeds, young shoots, etc. Thus, after visiting the weevil, the plant can only die.

The barn weevil, which destroys various crops, is one of the most harmful representatives of its family. And the rice weevil destroys not only rice, but also other dry foods.

The most dangerous enemy of cotton crops is the cotton weevil, which can destroy the entire crop. So you can see for yourself how harmful the weevil is to humans.

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 ... >>

Smartphone batteries will help in weather forecasting 19.08.2013

The weather has a strong influence on the work of transport services and public life, and therefore the accuracy of meteorological forecasts is sometimes very significant. But, despite the use of ground observation stations, satellites and sophisticated analytical systems, it is not yet possible to fully rely on even short-term forecasts. Developers in London want to improve the situation with the help of information from millions of sensors that protect smartphone batteries from overheating.

Currently, the OpenSignal app for iPhone and Android uses data from user smartphones to assess the quality of cell towers and Wi-Fi coverage around the world, and also provides data on the traffic consumed. Now the OpenSignal database is replenished with 700 thousand active users, but the application does not transmit identification data.

James Robinson, co-founder and CTO of the London-based company OpenSignal, decided to compare London air temperature data with changes in smartphone battery temperature and found a relationship. He reported to the American Geophysical Union about a method he had discovered to facilitate the collection of weather data, and sought the help of meteorologists and computers to develop a reliable method for determining the temperature of the street based on the heating of telephone batteries.

The developers are faced with the task of creating a system for accurate and timely data processing. It was necessary to eliminate the influence of many side factors caused by the location of the devices outside the open air, and to bring the temperature deviations caused by the design of the devices and the intensity of their use into compliance. Currently, the error is brought to 1,5 ° C, but the developers note that it will decrease with an increase in the number of users.

"The ultimate goal is to provide short-term local forecasts, which until now has been impossible for meteorology," commented James Robinson.

While modern monitoring systems rely on fixed stations receiving information at a specific point, OpenSignal can significantly improve weather prediction thanks to additional information from hundreds of thousands of mobile devices corrected using weather stations. It is noteworthy that many smartphones are also equipped with humidity and pressure sensors, providing additional meteorological information.
