The set of elementary particles produced in collisions of cosmic rays with the upper layers of the atmosphere. Among them are antiprotons. Scientists have speculated that the negatively charged antiprotons moving along the magnetic field lines of the earth, to form a kind of antiproton belt. However, to register these particles until recently it was not possible.

In the new study, experts analyzed data collected in low orbit for 850 days, the instrument PAMELA (a Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics — "The payload for the study of matter and astrophysics antisostavlyayuschey light nuclei").

As part of the "plasma crystal" in microgravity investigated plasma-dust structures. In plasma, the dust particles are introduced and created the conditions for them to accumulate huge charge, through which dust particles are arranged in crystals. In the absence of gravity multistory obtained crystal, and it all particles visible to the naked eye. Thus, in the experiment, the theoretical models of solid state physics are verified by direct observation. Speaking

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.

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

Institute of Physics, together with colleagues from Slovenia for the first time built a three-dimensional colloidal crystal

3D colloidal crystal in a nematic liquid crystal Scientists at the Institute of Physics, together with colleagues from the Institute of Stephen I. (Ljubljana, Slovenia) first built a three-dimensional colloidal crystal in the nematic liquid crystal.

Three-dimensional colloidal crystal in nematic liquid crystals:a)the final assembly stage of the two colloidal crystal smaller crystals (top view)b)dimensional reconstruction location of colloidal crystal particles of the data obtained by confocal microscope and a schematic view of one crystal plane.

Until recently most impetus for this liquid crystal was its use in a display device. However, despite significant progress

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

Baikal — a trap for cosmic particles

On the deepest lake in the world, Lake Baikal, the works on the reconstruction of the neutrino telescope, established over 10 years ago with the support of the Swiss and German specialists. This complex plays a critical role in the study of neutrinos, and hence the processes occurring in space.

Baikal — a trap for cosmic particles

Optical detectors are glass spheres with specific hardware inside.

The reconstruction is not needed because the telescope was in poor condition, since he did not yet old. Just local scientists did not accept the size of the device, and now it

Siberian scientists have created the airgel particle detectors

Siberian scientists have created the world’s first multi-layer airgel, which enables to record accurately measure the speed of elementary particles, for example, in the experiments at the Large Hadron Collider, told RIA Novosti senior researcher at the Institute of Nuclear Physics of SB RAS Budker Evgeny Kravchenko.

Aerogel — the least dense of all solid materials. It is 99.8% air and 0.2% — of nanosized silica fibers. Equipment using airgel works in accelerators or in the open space: on board the space station "Mir" airgel used to capture micrometeorites, and the American probe Stardust with it "caught" millions of
