How to see the color red more red

"I'm redder than red", Bob Marley once sang, but he probably never imagined that chemists will be able to "see" the tone. This had a little tweak of color-sensitive pigment of the human eye to teach him to absorb the wave of far-red range.Color vision of almost all animals provide specialized chemicals - chromophores, which are comfortably ensconced within the protein molecules adsorb light in the visible range. It is believed that the structure of protein molecules "nests" to a large extent determines the absorption spectrum of sitting inside the chromophore Read more [...]

Deceivers prominent nose

You can catch a liar, not only by his gestures and facial expressions. Spanish scientists from the University of Granada have shown that when a person intentionally introduces his companion astray, he heats the tip of the nose.Emilio Gomez Milan and Elvira Salazar Lopez Department of Experimental Physiology became the first to use in their research thermography (a method of obtaining images in the infrared, showing the distribution of temperature fields). Their discovery suggests that, depending on the internal state of its human body parts can be heated or, conversely, to cool.Thus, during sexual Read more [...]

The reason could be the great extinction bacteria

Absorbing Nickel archaea could exacerbate Permian catastrophe active methane production. A nickel they took from the Siberian Traps. At the end of the Permian period (about 250 million years ago), for some hundreds of thousands of years on the planet disappeared and 90% of all species.According to the fossil record, first life slowly withered due to the gradual acidification of the ocean and the reduction of oxygen in the air and water. Those who remained, killed volcanoes and meteorites. According to another theory, the atmosphere was methane deposits, usually hidden in the seabed, leading Read more [...]

Buildings enhance tsunami

During the construction of the coastal cities, we must remember that in some places the wave can be accelerated by 100 times. In relation to climate change is especially important. Scientists have recreated a city in miniature to model the tsunami hits the shore, and found that the building can exacerbate the incoming flow of water. The findings, presented yesterday at the annual meeting of the American Geophysical Union, said that even if the city as a whole is able to withstand the huge waves, some of the buildings and streets concentrated traveling wave, accelerating it to 80 × 100.
