The cure for cancer has become the elixir of youth

British scientists have discovered a protein responsible for the decrease in muscle tone during aging. As today by the newspaper "Daily Express", experts have determined that a cure for cancer, which is currently in the experimental stage, preventing muscle atrophy due to aging. "This discovery gives us the opportunity to create a cure for muscle regeneration system of man," - said the scientist.

The Japanese get the 113th chemical element

Japan's RIKEN research center in which a group of scientists got the first time in practice 113th chemical element of the periodic table of Mendeleev. 40-ies of the creation 113th Soviet physicists said element-atomists, but away from the theory did not work. The next year the Americans discovered chemical elements (from 93 to 104), Soviets (104 - 106), the Germans (107 - 112).

Discovered an old water flow on Mars

Vehicle-robot "Curiosity" NASA is on the surface of Mars just a few weeks, but has already found evidence that the planet's surface in the past flowing water. The robot was sent a picture of classical composition composed of stones, rocks and sand, and from mission control scientists say the size and appearance of rounded pebbles in the rock indicate that it is moved and shaped by water.

The rocks are described at a news conference at NASA's laboratory in Pasadena, California, and scientists say it is water laid to the place "a few billion years."

"Curiosity" is landed sixth on the surface of Mars August tasked with the help of your technical equipment to determine whether, in the past on this planet to provide the conditions for microbial life.

The robot is now generally held to test their systems and appliances, but this is when serious scientific work.

The ultimate goal is a robot vehicle to reach the central mountains Sharp, which is five kilometers high. Scientists expect that the vehicle has layers of rocks at the foot of the mountain from which it will be acquired new insights into the conditions that existed on Mars in the distant past.

Found billion carats of diamonds in Siberia

Siberian Branch of the Russian Academy of Sciences, said that the enormous deposits of industrial diamonds, found in a meteorite crater in Siberia, could initiate a new revolution in the industry.

The statement said that the crater Popigaj in eastern Siberia has "many billions of cards" of diamonds that can be used to make jewelry, but only for technological needs and exceeds all known global reserves of conventional diamonds.

According to the director of the Institute of Geology and Minerals in Novosibirsk Nicholas Pokilenka, carried by RIA Novosti, Siberian diamonds have different molecular forms of carbon, which are twice as strong as conventional diamond industry and have excellent potential.

He was confident that it could lead to a true revolution in several industries, but it will not disrupt the classic diamond market, because it can be used to make jewelry.

Diamonds are found in Meteor Crater Soviet scientists were in the seventies, but never exploited, because then thought to be a better synthetic diamonds for industrial use.

Until the dissolution of the Soviet Union, the site managed as a state secret.

Pokilenko says that this unprecedented hardness of diamonds result of extremely high temperatures as a result of the explosion, which occurred at a time when the meteorite hit the earth 35 million years ago and created a crater 100 kilometers wide.

"Junk DNA" is useful for the detection of disease

It turned out that the "junk DNA", which scientists have long thought that there is a function, plays an important role in the development of complex diseases such as diabetes, Crohn's disease, multiple sclerosis, lupus and cancer.

This discovery, the largest in molecular biology over the last ten years, it could cause a number of new therapies and drugs. The study, which lasted nine years, involved 440 scientists from 32 laboratories in the UK, U.S., Spain, Singapore and Japan.

The obtained very important clues to follow that science has discovered the key mechanisms that play a role in health and disease. This should be explored in order to be made ​​whole new medications or changed is existing.

The term "junk DNA" must now be discarded. From this research it is clear that this is part of the gene which is biologically more active than expected.

This term, the "non-coding DNA", scientists have figured out 40 years ago to describe the part of genetics that do not contain genes.

When in 1989. under the leadership of Nobel laureate James Watson began three billion-dollar project "Human gene", most scientists believed that the "junk DNA" has an important biological role.

Read of the human genetic code in 2000. years, and three years later published a complete map of the human genome.

Having completed the human genome project secessionist became clear that genes carry information for protein synthesis has about 20,000, which makes it one of only two percent of human DNA.

To be studied function of the remaining 98 percent of human DNA, which is believed to play an important role in the regulation of gene activity, which began in 2003. The program "ENCODE" in order to try to find the "non-coding part of genes", ie. "junk DNA."

Ozone on the slow road to recovery

Agreement on the Protection of the Ozone Layer, 25 years old prevented the disaster, scientists say the United Nations. In the Arctic zone record damaged reported in 2011, but the situation is more stable this year ...

The Montreal Protocol was signed on 16 September 1987. and decisively contributed to the preservation of the ozone layer. This layer of Earth's atmosphere filters out harmful ultra-violet rays, which contribute to global warming, causing skin cancer and damage vegetation.

The agreement was 25 years ago banned the use of substances such as chlorofluorocarbons, halons, carbon tetrachloride and methyl chloroform. Some of them were, at the time of signing the protocol, were a standard part of the refrigerator. "The agreement has prevented a huge disaster," says Gael Bråten, a scientist from the World Meteorological Organization.

Recovery for decades

According to the data of the institution, the emission of gases that damage the ozone layer suffered a culmination of the 2000th year - since then the situation has normalized, but the pollution is still there. "Even in this time of the ozone layer slowly disappearing," said Bråten (pictured ozone hole over Antarctica).

Forecasts say that at this rate the ozone layer could recover in mid-century - then again, the quality was the level before 1980. year. However, recover layer over Antarctica is much longer. "The gases that harm the ozone remains in the atmosphere for a long time - because the fill layer will take decades," he added Bråten.

Crickin of the crickets indicates the temperature of the air

According Dolber law is necessary to count the number of votes per minute crickets, subtract that number from 40, then divide the resulting figure by seven and finally add up to the 10th And that's the current air temperature.

The old folk wisdom says that crickets advertise more as the heat increased. Or to put it another way, their activity increases with increasing air temperature.

What you probably did not know is that the American physicist and inventor in the 19th Amos Dolber Century published an article "Cricket as a thermometer," in which he presented a formula expressing the coupling crickin "enthusiasm" and temperature conditions. This however only applies to the North American crickets Oecanthus Fulton, but approximately might also affect the field crickets.

According Dolber law is necessary to count the number of votes of small bites per minute, of that number, subtract 40, then the resulting figure divided by 7, and finally add up to the 10th The formula for computing in Celsius is: T> 10 + (N - 40) / 7

This means that according to this formula cricket at a temperature of about 40 degrees Celsius supposed to sound about 250 times per minute, or about four times per second. How does that sound plausible, let readers judge for themselves.

Crickets are insects related grasshoppers, and many of them are mixed with crickets. And an article in which Dolber 1897th published his remarkable formula was originally titled "The Cricket as a Thermometer" which means "cricket as a thermometer", although it is known that the story refers to the crickets.
