Go to the suborder of snakes include perhaps the most peculiar of creatures: their unusual appearance, the original mode of transportation, excellent behavior, poisonous species. These reptiles are probably the ones of the most ancient and amazing creatures. Their wit and cunning attributed due to evil spirits, for which he destroyed as soon as possible, and not only dangerous, but harmless snakes inform econews.uz. A total of 3,000 species are known today snakes, which belong to 16 families and more than 450 genera. Why can not kill a cobra its … Animals neurotoxin – the most lethal weapons of nature.

Almost all animals, other than to the Cobras, after being bitten by a cobra die for minutes after the poison got into the bloodstream. Neurotoxins are attached to the muscle receptors, as preventing nerve signals cause muscle contraction – that leads to respiratory failure and death. But blood vipers contains molecules that neutralize the deadly venom components of their own. This is the only difference introduced in the receptor Cobra bulky sugar molecule. Sugar masks the mounting position on the surface receptor – preventing bind the neurotoxin. If, however, remove the sugar, the cobra will become sensitive to its own venom, like other animals.

Hunt for the thermal radiation of some species of snakes, including rattlesnakes (Crotalus) and yamkogolovye, find prey in the infrared radiation of her body. Under the eyes they have sensitive cells, determining the slightest change in temperature up to a degree, and thus guiding the kite on location of the victim. This highly sensitive device allows the snake to find food in total darkness. Some boas also have sensory organs (on the lips along the mouth opening) that can fix changes in temperature, but they are less sensitive than that of rattlesnakes and snake yamkogolovyh Poor eyesight The majority of snake eyes is rather weak, which can usually detect only moving objects in the vicinity.

It all started when I was in second or third grade. Before going to bed every night, my parents and I would say overall, usually one or two chapters of a book I still could not manage on my own (the Chronicles of Narnia stand out most in my memory.) Maybe I knew I had to be near sighted since both parents were of me, or perhaps had seen someone that I admired on TV who wore glasses, but whatever the inspiration, I had the sudden desire glasses. One night after squinting and pulling the book closer to my face, trying to show my parents that my eyesight was failing and needed glasses. There must have been very convincing because nothing happened, and after two weeks of trying, I left the spot. My first pair of glasses Several years later, my vision actually start to decline, but was now much less interested in lenses that had been previously. Instead of demonstrating the need for my eyes checked, I did everything I could to hide the fact. I managed to hide for so long, in fact, that when I finally got new glasses for the first time, I was stunned. I had never seen (or own) detail or definition.

There were individual leaves on the tree outside the door and the signal on the other side of the street, had actually written words on it. I did not know that the vision of one person could be so good. It was not long, however, before I realized how much my glasses nerd made me see that I was.

Many cancer research programs believe that the utilization of nanotechnology will alter the entire process of cancer diagnosis, prevention, and even treatment.

New nano-devices are currently being developed with hopes of providing an efficient means of detecting and identifying cancer at its earliest stages, locating it directly within the body, and delivering medications to specific malignant cells. The technology will also be able to monitor the process, and record information regarding the effectiveness of anti-cancer drugs.

As they are developed, these nanodevices are tested in clinical trials. Researchers hope that the technology will transform this entire field of medicine, as well serve as multi-purpose tools for both diagnosis and therapy.
