What lizards and in what period temporarily cease to be cold-blooded?

Lizards are cold-blooded animals, but observations of Argentine black-and-white tegu lizards have shown that during the breeding season from September to December, their body temperature is about 10 ° C higher than the ambient temperature. The same feature, called reproductive endothermy, has been seen in some python species. Zoologists suggest that the constant warm-bloodedness of birds and mammals also initially arose as a temporary adaptation to increase stability during the reproductive period.

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 ... >>

QR codes on Moscow street signs 23.01.2014

Moscow schoolchildren will be involved in compiling descriptions of city streets on the Discover Moscow portal. Artyom Yermolaev, Head of the Department of Information Technologies, spoke about this today at a meeting in the Government of Moscow.

To date, by order of the city, it has collected information about 860 historical buildings, more than half of them are equipped with special signs in the form of plates with a QR code. Having scanned the information on the tablet, the user of the mobile device follows the link to the description of the monument on this portal, CNews was told in the Department of Information Technologies of Moscow.

Scanning information can be done using the mobile application of the same name, created within the framework of the project. In addition, the user can use the augmented reality function - when you point the camera at a building, text information with its description appears next to it.

Among other features of the resource, one can also note the ability to create and print a guide booklet by adding objects of interest, as well as the ability to create your own walking route in Moscow using the route editor.

More than 90 mobile device users have already used city travel apps
The portal is a joint project of the Departments of Cultural Heritage and Information Technology. Descriptions of buildings and streets on the portal are accompanied by photographs and an audio guide.
