The most significant scientific discoveries of the 21st century

The most significant scientific discoveries of the 21st century

Back in 2009, thematic channel "Discovery", summarized the work of scientists in the XXI century.

a list of the most significant scientific discoveries of this period has been published.

Discoveries made in the fields of medicine, biotechnology, space and climatology.

deglaciation

Climatologists are exploring the ice caps of Antarctica andGreenland concluded - ice planet melting much faster than previously expected. Most of the continental snow fields and glaciers may disappear, and the powerful Arctic ice fall off at high speed. With the pace of melting in the near future, the Arctic Ocean will be completely ice-free in summer. The consequences of melting mixed. On the one hand, it is melted glaciers will be a source of water for the billions in need, on the other - rising sea levels will lead to the disappearance of some islands and countries. According to the calculations of some reputable scientists, the end of the century, the level of the oceans of water should not rise more than 1 meter.

Complete melting of Greenland's ice will lead to rising sea levels by 7 meters.

The mapping of the human genome

Tight cooperation, scientists of the world have spent 10 years to decipher the entire human genome. In 2003, researchers finally uncovered the details of human structure at the molecular level.

Within each human cell are 23 chromosomes. If they are spread out in a row, their length is 91 cm.

The discovery of water on Mars

In 2008, the spacecraft PhoenixIt landed near the North Pole of Mars. His main task was taking soil samples for analysis. In one of the moments of operation of the apparatus onboard cameras noticed in samples a white powder. As soon as the next day began to compare shots, the last of them a white powder was already less. After careful analysis, scientists have concluded that the white powder is a water ice.

Scientific and ethical method of obtaining stem cells

In the 2007 year, independently of one another,American and Japanese scientists, from human skin cells were able to grow embryonic stem cells. Scientists decided to two problems. On the one hand - a new way does not violate ethical standards, on the other - are now from any of the DNA of human cells can be grown absolutely any body that for the transplant will not be rejected by the body.

prosthetic brain signals management

In 2009, a scientist became Pierpaolo Petruziellothe first person in the world, using the power of thought could control a biomechanical hand. Hand has been linked with nerve stumps scientist wire and electrodes.

Finding exoplanets

In 2008, astronomers "Hubble" telescope announcedthe opening of exoplanets orbiting distant stars. At a distance of 25 to 150 light-years from Earth may be a planet on which there is life.

The earliest ancestors of humanity

In 2009, the age of the skeleton was found in Ethiopiaabout 4.4 million years. As suggested by scientists - is an ancient ancestor of man, he walked on two legs, but at the same time good climbing trees. Analyzing the skeleton teeth, scientists have concluded that human ancestors ate a variety of foods.
