Radon helps reliably predict oncoming earthquakes

Scientists from Russia, Turkey, Georgia, and Greece studied the data on the concentration of radon in the ground in seismic fault zones on the Black Sea coast, as well as in the Aegean Sea. It turned out that the level of concentration of radon can be used as the indicator to predict earthquakes, at least in this region. The corresponding article is published in the Journal of Environmental Radioactivity.

Researchers analysed data for 2005−2013 relating to earthquakes in the Black Sea coast region — that is from Georgia to the Aegean Sea basin and from the Krasnodar Territory to the north of Turkey. The scientists have found that before most earthquakes the concentration of radon in the upper layer of the ground increases dramatically a couple of days before the tremors begin.

The method proved to be working in Italy before the earthquake in 2009. It was possible then to predict the earthquake, but the residents were not evacuated because the majority of experts did not take the forecast seriously.

Yamal scientists will put collars on arctic foxes to study their population in the Arctic

The scientists are going to install tracking collars on the arctic foxes in the Yamal peninsula in the summer in order to study their distribution throughout the region, including the area surrounding Yamal LNG, the liquefied gas production plant. The District Department for Science and Innovation announced this on Saturday, referring to Natalia Sokolova, a specialist at the Arctic Research Station of the Institute of Plant and Animal Ecology of the Ural Branch of the Russian Academy of Sciences and the leading researcher at the Arctic Studies Centre.

«These are pioneering studies. We are going to catch arctic foxes at their burrows, put collars on them and then follow their footsteps in order to get information about the habitats of the animals during breeding, what kinds of food they ‘specialise in', and to what extent the number of rodents affect their movements,» said Sokolova.

A method is developed of how to use fingers of heart failure patients to determine their state

Members of several medical and research institutions in Moscow together with colleagues from Germany presented a new way to determine severity of heart failure in patients. To develop the method the scientists examined tissues of the hand. The corresponding scientific article is published in the Journal of Biophotonics.

The method is based on two-photon tomography of the perivascular space — the zone between the capillaries and adjacent tissues. The width of the space is related to the amount of intercellular fluid, the excess of which leads to oedema. The more intense the swelling is, the higher the severity of heart failure. There have been no reliable quantitative methods to determine the level of severity before.

All subjects underwent echocardiography to evaluate how well the heart is functioning and videocapillaroscopy of the vessels of the nail bed of the fingers on the left arm. It was found that the perivascular zone is wider in the participants of the experiment with heart failure than in the healthy ones. The size of the perivascular space correlated with the degree of swelling and thickness of the layer of living cells of the epidermis — the surface layer of skin.

The method proposed by Russian and German scientists is painless and non-invasive — that is, the procedure does not discomfort patients.

A new type of optical ceramics developed in the Far East

Researchers from the Far Eastern Federal University (FEFU) have created optical nanoceramics with the addition of neodymium. The novelty surpasses the commercial glass and single crystals, used today in laser technologies, in terms of its physical and mechanical properties. The corresponding article awaits publication in Ceramics International.

Researchers used reactive spark plasma sintering at a temperature of 1200−1500 degrees to obtain transparent ceramics with the addition of neodymium.

The physical and mechanical properties of the new ceramics are noticeably superior to those that are typical for existing transparent ceramics. This is important when high-quality lasers are involved — in advanced laser range finders and communication systems, both terrestrial and space, which would be developed in the future.
