Do grasshoppers have hearing?

There are animals we tend to think of as being unable to hear, see, or sleep just because they look weird. The grasshopper is just one such animal. Yes, in many ways this is an unusual creature, but contrary to popular belief, he has ears and he hears!

There are many varieties of grasshoppers, but in general they all look about the same. All grasshoppers have strong jaws, three pairs of legs, and in most cases two pairs of wings. The first pair of wings is rigid and straight, the second is membranous and folds under the first pair. The hind legs, used by the grasshopper for jumping, are unusually long and well developed. Depending on the length of the antennae, grasshoppers are divided into two main groups: long-whiskered and short-whiskered.

The group of short-whiskered grasshoppers, also known as locusts, includes the common brown grasshopper. This species of grasshopper "sings" by vibrating its hind legs against its front wings. A grasshopper listens with ears located on the abdomen at the base of the hind legs. Long-whiskered grasshoppers, which include green meadow grasshoppers and narrow-winged grasshoppers, have antennae that are longer than their own body length.

In all species, only males “sing”, extracting the sound by rubbing the front wings against each other. The ears of these grasshoppers are located on the front pair of legs. So, although grasshoppers have hearing, their ears are rather unusual, and they are located in unexpected places.

What is the United Nations?

At times of particular world tension, we hear a lot about the United Nations. What's this? Where did it come from? What is their activity?

Here, we can only give a brief description of the United Nations. But this is what you should know. The United Nations is a government organization. It was created to prevent war, to create better conditions by solving problems through international efforts. The UN Charter was signed in San Francisco on June 26, 1945 by representatives of 50 countries.

According to the Charter, the UN has four purposes. The first is to maintain peace by resolving conflicts through negotiations or by taking measures to deter an aggressor or armed attack. The second task is the development of friendly relations between peoples on the basis of their equal rights and their choice of government. The third is to achieve international cooperation in solving economic, social, cultural and universal problems. And the fourth task is to be the center uniting the actions of all nations to fulfill these tasks.

The UN is divided into 6 main working groups.

The first group is the General Assembly. It consists of representatives of all members of the UN, each has one vote. It is the policy-making body of the UN.

The second group is the Security Council, which is responsible for keeping the peace. China, France, UK, Russia and the US are permanent members and have special voting privileges. The remaining members are elected by the General Assembly for a term of two years.

The third group is the Economic and Social Council, which consists of 19 members. Its functions are to improve the well-being of people, to further strengthen human rights and fundamental freedoms.

The fourth group is the Trusteeship Council, which takes care of the oppressed peoples of the UN and helps them gain self-government.

The fifth group is the International Court of Justice, which arranges open hearings.

And the sixth is the secretariat, the administrative and official body of the UN. Its main leader is the UN Secretary General.

New mirrors with video recording function from Neoline 30.04.2014

Neoline announced the start of sales of a new line of mirrors with a video recording function - G-tech. The flagship Full HD model Neoline G-tech X20 is supplemented with a rear HD camera. The second model of the series - Neoline G-tech X10 is based on the popular Ambarella A2 processor.

New mirrors have a number of advantages over traditional DVRs - they do not impair visibility, do not require additional brackets, and fit seamlessly into the interior of any car. But the main reason for the rapidly growing popularity of this form factor is that such a gadget can simply be left on the windshield and remembered only while saving videos.

Neoline G-tech X20 is a combined solution that combines a rear-view mirror, a "head" video recorder and an additional camera that captures what is happening in the rear hemisphere into a single complex.

The mirror surface of Neoline G-tech X20 is equipped with a special resistive element with a high degree of reflection. A 2,7-inch color display is built into the mirror, and the controls are located on the bottom of the case. To ensure that the image on the screen does not impair the visibility of the mirror, it turns off after 15 seconds of device operation. If desired, the motorist can leave the display on throughout the trip.

The auto gadget is attached to the standard rear-view mirror with rubberized clips that do not leave scratches. The 120-degree viewing angle allows you to capture everything that happens in adjacent lanes.

Neoline G-tech X20 can record video in Full HD resolution 1920x1080 pixels (without interpolation) at 30 frames per second.

The video is encoded in MP4 format - videos can be viewed on any device, be it smartphones, tablets or laptops. The novelty is equipped with all the functions of the latest generation of DVRs, including motion and shock sensors (G-sensor).

The rear camera, which comes with the G-tech X20 mirror, allows you to record what is happening in the rear hemisphere of the car in HD resolution. As a result, the device forms a complete picture of what is happening.

However, not all motorists need a rear camera - for such users, Neoline specialists presented a "light" Neoline G-tech X10 model based on the Ambarella A2 processor with one front camera. At the same time, the recording quality, additional functions, and ergonomics of the built-in video recorder fully correspond to the characteristics of the "older" G-tech X20, Neoline representatives report.

The mirrors are already on sale: the G-tech X20 model can be purchased at a recommended price of $180, and the G-tech X10 at a price of $140 rubles.
