Physicists received the first video of the experiment which is taking place in a museum of Dublin since 1944. Scientists recorded movement of bituminous weight through a glass funnel which for all the time of experience gave only eight drops. Authors of video of the experiment emphasize that despite seeming simplicity of experience to record the moment of falling of drops while nobody managed. Similar experiment make in Australia, but at the time of falling of a last straw at the end of the experiment the camera temporarily was switched off.
The European biologists found out that some insect legs can make movements without reduction of muscles, and studied the mechanism of their work that will allow to create in the future the artificial limbs of hands and feet. By the words of Tom Mateson from Great Britain University even when they removed all muscles from a joint of knee of a locust, the lower part of her shin continued to come back to a starting position. Then they thought that in it muscles in other part of a foot could be guilty, but it continued to move even then when they took away both main muscles of a foot. Mateson and his colleagues tried to understand how work muscles and other parts of feet of grasshoppers and a locust who allow them to jump on distances, in ten times exceeding length of their bodies. Biologists caught several adult individuals of a locust, opened insect legs and compared their structure to extremities of their relatives.
Till now, the accuracy of a laser distance is limited. These systems are founded on a passive way of a laser location so the signal worsens with 1/R 4 to R distance. In new research, physicists developed system which has the range one thousand times more exact. The system is founded on an active laser location where the signal worsens only to 1/R 2. The new system also has potential for achievement of sub-millimetric accuracy that gives the general improvement of productivity; such quality of a location is more than three orders better existing. This approach to a laser location can expand possibility of data acquisition to any interplanetary distances, at the expense of increase the sizes of telescopes. From Earth to Mars or Jupiter the laser location can already work at very modest sizes of a telescope, diameter in 1m at Earth and 15sm by the spaceship.
On July 11 in Germany began special scientific meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), which purpose is to resolve an issue of creation of the sea reserve largest on a planet at coast of Antarctic. Action will end on July 16. In Antarctic will be created the largest sea reserve, which will help to rescue thousands fishes, penguins, rare whales and seals from extinction. Now under consideration of CCAMLR are the offer on creation of the sea protected area in the Ross Sea of 2,3 square kilometers, including full protection of the area of 1,6 square kilometers.
The shock wave extending in a solar crown with a speed of 500-1 500 km/s, known also as Morton’s wave, gave the chance to specify significantly our ideas of solar magnetic field. When on the Sun there are coronals emissions of weight, on a place of their emergence swell the huge shock waves traveling round a star at high speeds. Where the magnetic field of a star is stronger, such waves representing plasma move quicker as lines of a field accelerate it. This unique line allowed the team headed by David Long from University college of London, to measure solar magnetic field more carefully, than ever. Distribution of a shock wave of Morton on the Sun is valid something probably for a solar tsunami: its speed depends on areas through which it passes. (Illustration NASA/SDO/AIA)
By the words of David Long they showed that the solar magnetic field is approximately ten times weaker than a magnetic.
The Solar system, as well as at comets, has a tail. To such conclusion came the American scientists supporting mission of the automatic device of NASA IBEX. It was brought by National administration of the USA on aeronautics and research of a space (NASA) to Earth orbit in 2008. According to NASA, to such results it was succeeded to come as a result of the complex analysis transferred by NASA IBEX for the first three years of work. The tail of Solar System consists of two streams of quickly moving loaded particles proceeding from our star from above and from below. Also in the tail of Solar System there are two more streams of slowly moving loaded particles on each side. Under NASA certificate, the American experts don’t know precisely, what extent of this loop. With help of the NASA IBEX tools hopes to receive idea of all structure of a heliosphere, and also to establish, where exactly there passes border of a shock wave on which there is a delay of a solar wind. Earlier interplanetary probe of NASA Voyager-1, started 35 years ago, crossed heliosphere border. The device became the artificial object first in the history which has left Solar system.
From a glacier on the Antarctic island Pine Island broke away the huge iceberg. Scientists waited for this event nearly two years. Scientists found a growing crack in a glacier in October 2011, and since then waited when the huge plateau completely will separate from a glacier and will be able to go to swimming on the ocean. On Monday the satellite from Germany TerraSAR-X saw that the crack reached from one edge of a glacier another. The German satellite is armed with radar with help of which can scan a surface even now when in Antarctic polar night. Scientists estimate the area of the broken-away iceberg approximately at 720 square kilometers. The biggest iceberg was a forward edge of ice shelf quickly slipping in the ocean. Huge icebergs break away from ice shelf of Antarctica of times in 6-10 years.
Today the mankind applies the atomic clock to counting of seconds; however the French scientists developed the alternative nuclear mechanism which promises more exact measurements of time. Optical mesh hours have a course error in only 1 second for 300 million years. As well as usual watches which rely on a pendulum for measurement of intervals of time, a new watch apply nuclear vibrations. In the majority of a modern atomic clock it is a question of fluctuations of atoms of cesium which throw out special microwaves with accurately set intervals. The new system of the atomic clock uses very short beams of light bringing into the raised condition atoms of strontium. By the words of Professor Jerome Lodewyck from the Parisian observatory in their watches are applied laser beams. These beams oscillate much quicker than microwave radiation; therefore they can divide them into smaller intervals to measure time more precisely.
The Israeli engineers developed flat and flexible sensors on the basis of carbon nanoparticles. This development will help with creation of the artificial skin, capable to transfer to the owner the feeling not only touches, but also temperature and humidity. The flexible sensors are capable to register mechanical loading in some 100-th shares of gram. Also they can feel temperature change within one degree and to react to fluctuations of relative humidity up to one percent. On mechanical sensitivity new development still loses to human skin, however it is already sufficient for many practical tasks. Flexible sensors are made of thin layers of the nanoparticles of gold connected together by diameter from 5 to 8 nanometers. Preliminary tests showed that they keep working capacity at repeated bending together with a rubber substrate, and also can be placed on different materials.
