Almost no global underwater research conducted by the RF now due to lack of money, says scientist

Deep-sea research does not receive sufficient financial support from the state, said oceanologist Anatoly Sagalevich.

«Over the course of many years we were able to conduct systematic global ocean research. It is practically non-existent now — there is not enough money. Our vessels are more busy with getting tourists to the Antarctic and the Arctic region. And though the scientists are trying to do some research along the way, but this is far from global projects of the past,» he said.

Sagalevich added that submersible vessels 'Mir' are listed on his laboratory’s balance sheet and «no one is going to spend any money on them». «There was a time when I was trying to reach an agreement with some businessman or another regarding financial support for the projects, but it’s not always appealing to them, because scientific research brings prestige to the state, but not profit,» he said.

Scientists found a way to protect optical fiber in biomedical applications from biomolecules

Scientists from Russia, the Czech Republic, and the United States have proposed a new way of protecting the surface of optical fibers from biological molecules. Such optical fibers are promising for use in biomedical applications, including biosensors, the press service of Tomsk Polytechnic University (TPU) informed.

«Proteins stick to the surface of an optical fiber line and thus prevent it from transforming the signal. To solve the problem we have developed a new method of modifying the surface of a fiber by making it bio-inert — we covered a fiber with highly hydrophobic organic compounds so that they do not interact with proteins in aqueous solutions,» Pavel Postnikov, one of the authors of the study and associate professor of the Research School of Chemistry and Applied Biomedical Sciences is quoted by the press service as saying.

Postnikov explained that a thin layer of gold is sprayed on the fiber to form a coating, then light is directed through it so that plasmon resonance is excited, due to which the iodonium salt decomposes, organic radicals are formed and bind firmly to the fiber surface. Experiments have shown that after the modification the fiber ceases to interact with molecules.

Krasnoyarsk scientists investigate the reasons for a fish hunger strike in the river in Taymyr

Experts from the 'Taymyr Nature Reserve' are trying to discover the reasons for the fish hunger strike (sic!) in the Pyasina River. The expedition to the Taimyr Peninsula in the Krasnoyarsk Territory has been concluded recently, which aim was to study the phenomenon, informed the press service of the directorate of the institution.

«Stomachs of most of the fish studied (nearly 90%) were absolutely empty, the fish just did not eat anything. The reasons for this are being studied now,» Nikolai Moshkin, a scientist member of the expedition, is quoted by the press service as saying.

He explained that the scientists selected samples of plankton and benthos (organisms living in the river bottom) at four locations in order to study the food base of the fish. Now the scientists expect that the results would help come to a conclusion whether the quality of the forage reserve and the population of several fish species have declined. Among these fish species are Stenodus nelma (aka sheefish or inconnu), broad whitefish, muksun, Coregonus sardinella (aka sardine cisco or least cisco), Coregonus vandesius, peled (aka northern whitefish), pike, burbot, Arctic grayling, and also pink salmon (aka hunmpback salmon), but the scientists have not been able to detect the presence of the latter in the reservoir.

Satellites created by schoolchildren from the Sirius Centre transmitted first scientific data

Scientists have received the first research data from the scientific and educational satellites 'SiriusSat-1' and 'SiriusSat-2'. The satellites were created by the students of the Sirius Centre with the help of the specialists from 'Sputnix' (a resident company of the Skolkovo Foundation), the press service of the Skolkovo Foundation informed.

«The detectors of charged particles and gamma-radiation installed on the satellites 'SiriusSat-1' and 'SiriusSat-2' make it possible to research rapid variations of electron fluxes at the inner boundary of the outer radiation belt and at the boundary of the South Atlantic Anomaly. The data which will be transmitted to the Earth will include both monitoring data, i.e. particle counting rates of one time per second, and detailed data on all interactions in the detector, which will allow study of temporal and spectral characteristics of micro precipitation of electrons from Earth radiation belts», Vitaly Bogomolov, a senior research fellow at the Research Institute of Nuclear Physics (SINP — Skobeltsyn Institute of Nuclear Physics) of Moscow State University is quoted in the message as saying.
