How do oysters eat?

When you look at an oyster, you involuntarily wonder what else it does, besides just lying in its shell? How does she breathe, eat and how does she protect herself from enemies? An oyster is not just a piece of living matter, but rather a complex creature that performs many vital operations. She has various organs, blood, nervous system and so on. But for now, we'll just look at how the oyster eats.

First, what does she eat? The oyster's diet includes tiny algae and various microorganisms, that is, organisms that can only be seen under a microscope. These little creatures enter the body of the oyster along with water, which constantly "washes" its internal organs when the shell is opened. This food is taken from the water and coated with mucus secreted by glands located in the gills of the oyster. The oyster selects some microorganisms for food and rejects others that are unsuitable for it, or too large, or not in the right shape. But we do not know how she manages to make this choice.

Oysters have a alimentary canal that begins with a mouth opening with four tendrils guarding it. These tendrils take in food and sort the edible from the inedible. The narrow esophagus leads to the stomach, a large sac-like organ. Something like a twig, about a centimeter long, sticks out inside the stomach. This twig, rotating, mixes and grinds small particles of food. It also contains enzymes that digest food.

In addition, a large digestive gland is located around the stomach. In this gland there are blood cells that envelop food and digest it inside their body. Of course, this is very general information about the process of feeding oysters. We have given them just to give you an idea of how oysters are eaten.

How fast is the speed of light in a vacuum?

The propagation speed of electromagnetic waves (including light waves) in free space (vacuum) is one of the fundamental physical constants. Its huge role in modern physics is determined by the fact that the speed of light is the limiting speed of propagation of any physical influences and does not change when moving from one frame of reference to another. No signals can be transmitted faster than the speed of light.

The magnitude of the speed of light connects the mass and total energy of a material body through it, the transformations of coordinates, velocities and time are expressed when the reference system changes, it enters into many other relationships.

According to modern data, the speed of light in a vacuum is 299 meters per second.

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 ... >>

HELIOS displays 04.06.2020

Displays are perhaps the most vulnerable areas of consumer electronics. They remain relatively expensive components. At the same time, careless handling, or a blow as a result of a fall, can lead to the most sad consequences for them. The task of scientists is to create a fundamentally new material that does not have such shortcomings. Scientists from Singapore managed to solve it successfully. They have developed a unique HELIOS material that could become the basis for future technology displays.

It is based on a fluoroelastomer and a surfactant, and the material itself looks like a flexible transparent plate. Fluorelatomer is a synthetic rubber based on fluorocarbon. One of the remarkable properties of the new material is that it has a high dielectric constant. This allows you to get the brightness of the glow up to 20 times higher with a four-fourth lower supply voltage. Thus, displays based on it can be incredibly energy efficient.

HELIOS screens are not only flexible, but they can also "heal" themselves. At the same time, this happens under normal conditions without the need to create certain conditions, for example, elevated temperature. Such screens will not be afraid even of breaks and through punctures. The technology described by Singaporean scientists seems to be promising and can be in demand in various fields.

The developers are confident that HELIOS technology can be used for public wireless displays and even in robotics.
