Where were mammoth bones revered as the relics of a Christian saint?

One of the martyrs revered by Christians is Saint Christopher, who, according to legend, lived in the 3rd century and was of enormous growth. In the Orthodox tradition, he was depicted on icons with the head of a dog or a horse, among Catholics - in the form of a giant carrying Christ across the river.

In Valencia, a mammoth tooth was venerated as part of his relics, and a mammoth femur as the hand of St. Christopher was solemnly carried through the streets with prayers for rain.

Do birds have ears?

Since birds are flying animals, almost everything in them is designed for this complex activity: all internal and external organs, including the nervous system and sensory organs. For example, keen eyesight is a vital necessity for flying animals. This is one of the most important features of birds. In proportion to the size of the animal, bird eyes are much larger than those of other vertebrates.

Some birds are able to see different images with each eye. Other birds can make out very small objects and fine details from afar. It is very important for birds to have good hearing, and they have it. Birds have ears. The organs of hearing, orientation in space and the ability to balance while moving are all connected with the ear.

Despite the fact that the beak of many birds is hard, ossified, many birds have a good taste. Nou birds have almost no sense of smell. Flight requires a lot of energy. Therefore, the metabolism in birds is very fast. The body temperature of the birds is very high: between 40 and 45 degrees Celsius. Rapid pulse and high breathing rate. For example, the sparrow's heart beats over 500 times per minute.

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 ... >>

Neurocomputer interface implanted in human 30.07.2022

The brain-computer interface has become a reality in the United States (albeit limited so far). Synchron says it has become the first company in the country to successfully implant a brain-machine interface into a human.

Doctors at New York's Mount Sinai West Medical Center implanted a Stentrode device into the motor cortex of a patient who agreed to take part in the COMMAND experiment sponsored by Synchron. Its purpose is to evaluate the usefulness and safety of brain-computer interfaces in enabling people suffering from severe paralysis to control the device without using their hands.

Ideally, Stentrode's technology should enable these people to self-send emails, text messages, and perform other digital tasks that healthy people take for granted.

Surgeons installed the implant through an endovascular procedure that avoided major open-brain surgery by inserting it through the jugular vein. The operation went "extremely well" and, according to Synchron, the patient was able to return home within 48 hours. The ongoing experiment in Australia is also going well, with four patients who received implants a year ago doing well.

It is clear that by the time when doctors can offer the installation of Synchron brain-computer interfaces to all patients in need, a lot of time will pass.

In July 2021, the company received approval from the US Food and Drug Administration (FDA) to perform an interface implantation operation in humans under the COMMAND pilot program, which is still active at the time of this writing.

The US procedure was a significant step forward. It will allow people suffering from paralysis to regain the ability to independently control their lives. It also testifies to the victory of Synchron in the competition - Elon Musk, for example, has not yet received FDA approval for the use of implants developed by his company.
