Far scientists have discovered a biological method of producing silver nanoparticles

Biotechnologists have achieved unique results. In the laboratories of the Far Eastern Branch of the Russian Academy of Sciences (FEB RAS) not only mastered the "green technologies" in getting the silver nanoparticles, but also learned how to control the size of the smallest particles, reports DW-Ross.

Hundreds of meters of salt water separated from biotechnologists unique discovery. Nanotechnology came from the bottom of the ocean. Inhabitants of the depths — sponges — hit the tubes researchers. First, cells from isolated ribonucleic acid. Then feed these molecules specially grown bacteria. And a scalpel to cut them in

Fires in Southeast Asia take away lives of 15 thousand during the El Niño

Fires in Southeast Asia take away lives of 15 thousand during the El Niño Facts

According to scientists, forest fires in Southeast Asia each year take the life of 15,000 people when the El Niño phenomenon covers the region. The death of so many people due to severe air pollution to the local increase in the concentration of ozone, which are stress factors, such as the heart and to the lungs.

U.S. scientists Environment analyzed the levels of harmful particles in the air in the south-east Asia in the period from 1997 to 2006. It should be noted

Russian physicists launched in Kazakhstan set to study cosmic rays

Experts of the Lebedev Physical Institute of RAS (FIAN), launched in the Tien-Shan Research Station in Kazakhstan, a new experimental installation "Horizon", designed to study cosmic rays — streams of elementary particles from space.

Unit is designed specifically for the registration of Cerenkov radiation — Glow Produced in a transparent medium moving charged particles — and the charged particles of extensive air showers (EAS), a cascade of secondary particles that arise from "hitting the atmosphere" of the particles arriving at Earth in the cosmic rays. With the new installation specialists station going to check the existence

Russian scientists have taken an anti-cancer drug for its intended purpose

Scientists from the Institute of Biochemistry and Physiology of Plants and Microorganisms, Saratov State University and the Moscow State Academy of Fine Chemical Technology have developed a new type of composite nanoparticles, which are successfully used for the delivery to the tissues of porphyrins. With the help of luminescence can control the distribution of nanoparticles in living tissue and enhance the photodynamic effect.

When receiving the composite particles are synthesized first silver nanokubiki size 30-60 nm. Further, based on these obtained gold-silver nanocages, which create a porous silica nanoshells of thickness from 20 to 100 nm.

Astrophysicist Heidi Newberg of Rensselaer Polytechnic Institute and his colleagues suggest that the Earth befalls a large flow of dark matter from another galaxy. Scientists have long believed that about 90% of the mass of the universe is composed of particles called dark matter. This conclusion is

Today, expect strong magnetic storms

Sun

9.09.11.Dve powerful X-ray flare that occurred on the eve of the sun, can cause magnetic storm on Earth, which is expected to start on Friday, September 9, the head of the center space weather forecasts of the Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation Sergey Gaidash.

Geomagnetic storms — is strong perturbations of the magnetic field of the Earth, which occur due to strong emission of ionized particles from the solar atmosphere. High-speed solar wind streams (ionized particles from the solar atmosphere) hit the Earth's magnetosphere, if the planet is in their way.

As a result

Work on the project of nuclear fusion is conducted around the world for nearly sixty years and is still not complete. The problem is that the implementation of the nuclear fusion reaction to a device in which a period of time necessary to keep the core in light of the atoms specified concentration with an energy of 100 keV. According to the Lawson criterion to apparatus for nuclear fusion was energetically favorable necessary that
