Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

desert crocodiles 09.09.2002

Biologists were struck by an unexpected discovery: in the south of the Sahara, in Mauritania, several groups of crocodiles were found.

Irish zoologist Tara Shine examined the temporary reservoirs of the Mauritanian part of the Sahara, filled with rare rains, and then dry up. In 19 percent of them, Shine was surprised to find crocodile populations. By all indications, these are Nile crocodiles, differing only in small size: the length of an ordinary Nile crocodile is up to five meters, and a desert one is one and a half meters.

Another feature: Saharan crocodiles do not attack people. Perhaps their small size makes them non-aggressive. Local tribes revere crocodiles as gods of water, so rare in these places. In some places, between the sand dunes and the rocks heated by the sun, you can find temporary swamps overgrown with grass. They store water from six months to four months a year. There are crocodiles. In one swamp there can be from one to three dozen individuals.

What do reptiles do during the dry season? They fall into a kind of hibernation, clog in holes or under stones, almost or completely losing mobility.

Local residents have long told visiting scientists that one can meet a crocodile in the desert, but until now these reports were considered unreliable.

A random story from the life of a radio amateur:

I remember that Funai TV was brought to us. Brought by the gypsies. I knew that they are an impulsive and temperamental nation, but when I saw the TV screen, I realized how much! The whole screen was dented, it looked like the windshield of a car, which was hit with something sharp and heavy, but the crack did not spread all over the screen! As a result, I not only did not take it for repair, I did not even turn it on in order to avoid the explosion of the kinescope. By the way, I was very surprised that the people who brought it to me for a long time and obsessively persuaded me to do it, although I told them in plain text, for a long time, in raised tones, that using such a TV could lead to an explosion. In general, thank God, otbrehalas.

Random fact "Did you know?":

Measurements have shown that the air in the Paris metro is six times more saturated with microscopic dust particles than the air in the streets of the French capital. Particles of iron, manganese, aluminum, nickel and silicon predominate. These are products of abrasion of rails, wheels and brake pads of trains. The metro management intends to increase ventilation at the stations and more often launch special cars with vacuum cleaners.

Random article of the Great Encyclopedia for Children and Adults:

What came first - telephone or fax?

The fax came before the telephone. The prototype of the fax machine was invented as early as 1843, and in 1865 the Italian Giovanni Caselli's device began to be commercially used on lines in France and between Moscow and St. Petersburg. In this apparatus, called a pantelegraph, the image for transmission had to be applied with a special insulating varnish on lead foil. However, this technology was not successful and gave way to other methods of communication. The mass development of facsimile communication became possible in the 20th century due to the emergence of more accessible channels - first telegraph, and then telephone and radio.
