Who is losing horns?

Deer shed their antlers every spring. If you're lucky, the fallen horn can be found in the forest. Instead, only a small bone "stump" remains. After a month or two, new ones grow in place of the old horns. While the horns grow (they are called antlers at this time), they are soft, permeated with blood vessels and covered with short velvety fur. It is only then that they ossify, and the dead skin falls off.

Usually only males have horns. They use them during mating tournaments. But reindeer females also have antlers - they need them to rake snow in the tundra in search of food. The size and branching of the antlers are very different in different deer. And in a moose they are flat, like a shovel. By the way, this is the largest representative of the deer family.

Random interesting fact from the Great Encyclopedia:

What does the moon smell like?

Apparently, gunpowder. Only twelve people have walked on the moon, and they are all Americans. It is obvious that the astronauts could not sniff the Moon in airtight spacesuits, but lunar dust is a terribly sticky thing, and when the Americans returned to the ship, they dragged a lot of "dirt" on their soles.

In their report, the astronauts reported that lunar dust feels like snow to the touch, smells like gunpowder, and tastes quite tolerable. In fact, almost half of the lunar dust is silicate glass made from silicon dioxide, which arose as a result of meteorite collisions with the surface of the Moon. In addition, lunar dust is rich in iron, calcium and magnesium, which are part of various minerals.

NASA has a small group of "sniffers" who sniff every piece of equipment that goes on the next flight. This is done so that none of the items could change the fragile climate balance created on the International Space Station.

The popular myth that the moon is made of cheese comes from the 1564th century. The very first extract from Proverbs (XNUMX) by John Heywood says: "The moon is made of green cheese." It seems to the authors that in this context the word greene ("green") is used in the sense of "immature" rather than "having a green color", since young cheeses often look "speckled" - almost like the Moon with its famous craters.

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 ... >>

Car body will change stiffness in an accident 19.08.2017

Self-driving cars should reduce the number of traffic accidents, as a computer makes significantly fewer errors than a person. However, Waymo is also thinking about what will happen to the pedestrian if the computer system does fail.

Waymo has patented a technology that will change the rigidity of the car body in a collision with pedestrians. We are talking about the possibility of changing the rigidity of the bumper, fenders and hood using a system of cables, rods and springs. At the moment when the car's sensors determine that a collision with a pedestrian is unavoidable, the computer system will do everything to protect the person from serious injury.

The patent was registered back in 2015, so there is no guarantee that the development will be implemented in commercial vehicles. It also remains an open question how much the safety of the driver and passengers in such cars will be reduced.
