The slowest experiment in the world

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 insect legs will help to create the artificial limbs

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.

World’s largest sea reserve in Antarctic

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.

One of the biggest iceberg of Antarctic Glacier

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.

The atomic clock for more exact measurement of time

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.

Spider webs use electricity to catch insects

According to scientific results, a spider webs and positively loaded subjects, such as insects flying by, attract each other. After all, moving wings of insects not simply hold the owners in air, they develop electricity. Bees can develop electric charges up to 200 volts, which is quite enough to separate pollen from flower stamens. Within the research Victor Manuel Ortega-Jimenez and Robert Dudley studied sensitivity of a spider webs to electrostatic charges of insects and water drops. In a basis of this work was defined earlier research as a result of which was necessary extent of deformation of a web from hit of victims in it. We know that for victim capture the spider webs is capable to change the form. But how? The researchers collected all web in the territory of a university campus in Berkeley. Scientists carried out a series of experiments to check reaction of a web to subjects flying by, more exact – a drop of water. As scientists noted, the threads of a web located radically and especially on a spirals, were quickly attracted to the electrified bodies. In check experiments in which were used insects and drop of water without electric charges, it was not observed such change of a form of a web.

X ray video showed the bats in the movement

The researchers were able to capture the X ray video, in which the bats in the flight. By the words of scientists, the bats have energy in their bicep. This energy helps the bats in the air to be more powerful among the other winged mammals. The researchers used the imaging technology for X ray video making, thanks to which they saw the bats in the air. By the words of the leader of the research Nicolai Konow, (University of Brown), the bats are storage their energy in the triceps tendon. This is extra ability for bats, as the tendons of mammals are thick to be stretched. Using the 3d technology named by XROMM the group of researchers was able to see the internal skeletal movement. The technology of XROMM of bone morphology models is the same as the X ray video biplanar. Also the researchers found another method named by fluoromicrometry. In this method the radio markers are placed into muscle.

Chemists found a new way of seawater desalination

Researchers from the Texas University in Austin (USA) and Marburg University (Germany) thought up a new way of seawater desalination. They created small electric field which removed salt from sea water. The new method doesn’t demand big expenses of energy (the device can work at ordinary batteries) and it is much simpler than methods of water desalting existing nowadays. Now process is patented and is in commercial development. For seawater desalination researchers gave the small tension (3 V) on the plastic chip with sea water. The chip contains two micro channels on which are built-in joint electrodes for creation of area of exhaustion of ions in sea water. Change in electric field leads to that salt “is pulled together”, goes to one canal, and desalinated water in another.

Scientists simplified a rubber hand illusion

Researchers from the Italian University Chieti-Pescara found out that in classical experiment with a rubber hand illusion isn’t required the real tactile feelings to the person. Now the expectations are capable to replace them. Classical experiment with a rubber hand, which was described Botvinik and Cohen in Nature in 1998, is carried out as follows. The volunteer is seating at the table where the right or left rubber hand lies. And the corresponding hand of the participant of experiment hides behind a screen or under a table. The experimenter two brushes starts touching at the same time a rubber hand and a hand of the volunteer. Approximately two-three minutes later two thirds of experimental have a resistant feeling of that the rubber hand belongs.
