How does a snake manage to swallow a pig?

Unlike many other animals, snakes are not able to chew (or even dismember) food before it is "used", and therefore are forced to swallow their prey whole.

To do this, nature endowed them with the ability to greatly stretch the oral cavity when swallowing large prey. And this ability is provided by the connection of the bones of the facial part of the skull, not according to the "hinged" scheme, as in most animals and humans, but with the help of elastic ligaments.

 Random interesting fact from the Great Encyclopedia:

Why did Bulgaria issue a coin with a face value of 1,95583 leva?

In 1999, Bulgaria equated its currency lev to the German mark. A few years later, the marks were replaced by the euro at the rate of 1,95583 marks = 1 euro, and the lev became pegged to the euro in the same ratio. When the country's accession agreement to the European Union was signed in 2005, the Bulgarian National Bank issued a commemorative coin with a unique denomination of 1,95583 leva as a symbol of Bulgaria's desire to adopt the euro in the future as well.

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 ... >>

24-bit 256-channel ADC for ADAS1131 tomographs 07.08.2014

Analog Devices has unveiled an analog-to-digital converter that it claims will reduce the complexity and cost of electronics in CT scanners.

The ADAS1131 ADC is the industry's first 24-bit, 256-channel current-to-digital converter. The ADC is produced in a 15x15 mm CSP-BGA package with 324 ball leads spaced at 0,8 mm pitch. On a printed circuit board, it takes up about a third less space than similar chips, which at the same time have half as many channels. With a choice of 0,8mm lead pitch, designers can install the ADAS1131 on standard printed circuit boards that cost less than custom high-density boards.

The ADC includes not only 256 low-power, low-noise, low-input current integrators, simultaneous sample-and-hold circuits, and two high-speed ADCs with configurable sampling rates, but also all internal buffers, as well as decoupling and bypass capacitors. Thanks to this, the number of external components can be reduced, and the PCB layout can be significantly simplified. The converter consumes 3 mW per channel at any given bandwidth, which is equivalent to competing products with only 128 channels.

The ADAS1131 chips are currently available to order for $304 each.
