Do bats have teeth?

There are over 2000 species of bats, and it is only natural that there are many differences between them. Most bats feed on insects, but in tropical areas there are some that feed on fruits or pollen. And there are bats that eat fish, other bats, smaller ones, or even drink the blood of animals.

The largest bat in the UK has a wingspan of 33 to 36 centimeters with a body length of 13 centimeters. It lives in wooded areas and feeds on large insects. Fruit-eating bats live in the tropics. Do they have wide, flat teeth that they use to squeeze the juice out of fruits? Those bats that feed on pollen have long tongues that allow them to climb inside the flower.

Vampire bats feed only on blood. They suck blood from horses, cows, dogs, chickens and even attack people. With two sharp upper incisors (front teeth), they bite through the skin of their prey, after which they lap up the blood that comes from the wound. Bats can have 20 to 38 teeth.

Curiously, no species of bat with 22 teeth is known. Some of the insectivorous bats have 38 teeth. So it's easy to see that teeth are important to them. Did you know that bats have been around for so long that they can be considered one of the oldest orders of mammals?

60 million year old bat fossils discovered! The oldest known image of a bat was discovered in one of the Egyptian tombs. This image is about 4 thousand years old.

What future awaits our luminary - the Sun?

The sun was formed about 5 billion years ago and for at least 4,5 billion years, thanks to the reactions of converting hydrogen into helium occurring in its central regions, it has been steadily radiating warmth that is beneficial for us, the inhabitants of the Earth.

According to modern astrophysical concepts, in 8 billion years the Sun will become a red giant. At the same time, its luminosity will increase hundreds of times, and its radius - dozens. This stage of the evolution of our star will take several million years, after which the swollen Sun will shed its shell and turn into a white dwarf.

It is surprising that back in 1895, long before the emergence of theoretical astrophysics, the presence of a red giant stage in the evolution of the Sun was predicted by the English writer HG Wells in his novel The Time Machine, which opened the history of modern science fiction. Moving in time "in huge steps, each a thousand years or more," the hero of the novel watched the Sun "become bigger and dimmer," and then "the huge red dome of the Sun obscured a tenth of the darkened skies."

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 ... >>

Single-chip systems Qualcomm IPQ8074 and QCA6290 17.02.2017

Qualcomm introduced IPQ8074 and QCA6290 single-chip systems supporting Wi-Fi 802.11ax. The first is designed to serve as the basis for wireless network equipment, and the second is designed for client devices. According to the manufacturer, he is the first to offer such a kit.

Adopting 802.11ax can quadruple the capacity of Wi-Fi networks while extending the battery life of mobile devices. The new SoCs support 12-stream connectivity (eight streams in the 5GHz band and four in the 2,4GHz band), MU-MIMO configurations, 80MHz channels. Another feature is support for OFDMA (Orthogonal Frequency Division Multiple Access) modulation used in cellular networks and traffic scheduling.

The manufacturer notes that the full benefits of innovations are revealed in equipment that supports 802.11ax, however, devices of previous generations that support 802.11ac and 802.11n will work better in 802.11ax networks.

In the IPQ8074 description, the manufacturer highlights 8x8 MU-MIMO support and a high degree of integration. The single-chip system configuration includes an RF unit, MAC and signal processor, as well as a quad-core 64-bit ARM Cortex-A53 processor and a dual-core network accelerator. The microcircuit is designed for release according to the standards of 14 nm.

In turn, the QCA6290 supports 2x2 MU-MIMO and a peak speed of 1,8 Gb / s, which is achieved through the DBS (Dual Band Simultaneous) mechanism, which allows combining channels in the 2,4 and 5 GHz bands, and high-order modulation (1024 QAM). Another advantage is proprietary power optimization that complements the built-in 802.11ax power saving technologies.
