Where do squirrels live?

Squirrels are such a familiar sight in our parks and forests that one might think that our country is their homeland. In fact, squirrels live in all parts of the world except Australia!

There are many different types of proteins. They can be the size of a cat or as small as mice. They may have soft, fluffy fur or spiky quills. They can jump from branch to branch, or they can fly from top to top using folds of skin that act like parachutes. Some of them even live on earth. But almost all of them are kind fussy little animals with long fluffy tails and beady eyes.

Squirrels form a special family of rodents. They are divided into two main groups: ground squirrels and tree squirrels. Ground squirrels include marmots, chipmunks, and prairie dogs. The most famous among tree squirrels are small red squirrels, gray squirrels, fox squirrels and eared squirrels.

Tree squirrels spend the winter, as a rule, in some kind of hollow, which they line with leaves and branches. In the spring, they often build themselves another house on top of a tree. There they raise their offspring, numbering four to six squirrels. Harmful red squirrels often eat eggs and chicks of birds.

However, most squirrels feed only on acorns, pine cones and nuts. Squirrels have to store enough food to last through the cold months. Flying squirrels differ from all others in that they have folds of skin on their sides that can straighten out. When they spread their legs, the folds between them act as glider wings and help squirrels fly through the air.

Flying squirrels live in warm areas in North America, Europe and Asia. You don't see them often because they usually sleep during the day. In Asia, there is another interesting species of squirrel that changes color during the mating season, like male birds.

After whom did scientists name the gene whose deletion makes mice smarter?

In 2010, American scientists from Emory University discovered a gene in mice that, if removed, increased their mental abilities. Mice without this gene found their way out of the maze faster and remembered objects better. The same gene exists in humans, but it is not yet possible to talk about the benefits of removing it in both humans and mice, because it can have an as yet unexplored effect on other types of brain activity. Scientists gave him an unofficial nickname - "the Homer Simpson gene."

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 ... >>

Fiber optic network as an earthquake predictor 30.10.2017

Earthquakes are one of the most destructive natural disasters. Sometimes even a few minutes of warning about them can be decisive. And now Stanford scientists have come up with an interesting proposal on how to create a truly global network for early earthquake detection.

Now such a system requires the installation of highly sensitive sensors that will measure the slightest tremors that can signal that a major disaster is near. But standard sensors can't cover everything, so a group of Stanford scientists came up with another solution: a fiber optic network.

Fiber optic cables transmit information at almost the speed of light and are used by telecommunications companies around the world. But they are also used by oil and gas companies to monitor small shocks caused by drilling equipment. With such measurements, a characteristic of cables called "backscatter" is needed, with the help of measuring the movement of cables and recording seismic events.

There is a laser at one end of the cable that sends out light. Part of the light hits impurities and defects in the glass walls of the cable and is reflected: this is the "backscatter" that was discussed. The signal received under such conditions can change depending on whether the part of the cable where the reflection occurred was moving, and fixing such signals can give scientists a map of seismic activity over a large area.

Typically, fiber optic detectors are attached to pipes or other equipment, but to detect earthquakes, researchers need loose cables, which is considered almost impossible, as most people think a loose cable will generate too many signals to be useful.

But by using a five-kilometer cable on the campus of the university itself, the researchers demonstrated that optical fiber is suitable for such purposes. With their network, they were able to detect about 800 seismic shocks, including an earthquake in Mexico and two small local earthquakes of 1,6 and 1,8.

This means that scientists can detect earthquakes using the already existing fiber optic network of communications companies. Of course, such cables are not as sensitive as traditional seismometers, but they are much cheaper and provide more area coverage.
