Lake Baikal: Fire and Ice

Electronic and other media are reposting a popular video where a truly Siberian fisherman creates fire from the ice of Lake Baikal in front of amazed journalists. A pillar of fire on the frozen surface of the legendary lake is a mindbending show, but it looks natural both for the locals and for scientists The burning flare on the ice of Lake Baikal on February 1, 2017 was ...

Live Silicon of Lake Baikal

... from power production to metallurgy. Since diatom nanotechnologies do not need any extremely high temperatures and “heavy chemistry”, they excite strong interest of experts in different areas. Diatoms are the most abundant group of algae in Lake Baikal, comprising both widespread and endemic species. Find below the results of molecular genetic studies carried out by young researchers of the Limnological Institute (Siberian Branch, Russian Academy of Sciences, Irkutsk) when they “reconstructed” ...

The Fish of Lake Baikal Against Atherosclerosis#On a New Experimental Object for Medicine

To design efficient methods for making early diagnoses and then treating this disease, it is necessary to acquire thorough knowledge about the mechanisms of its development. Amazingly enough, some fish of Lake Baikal can help in solving this problem Cholesterol and other fats travel in the bloodstream as  lipoproteins . These particles have a rather intricate structure composed of a “drop” of fat and specialized proteins that help the drops to interact ...

Ecological Crisis on Lake Baikal: Diagnosed by Scientists

By  Oleg A. Timoshkin ,  Valery V. Malnik ,  Maria V. Sakirko , and  Christian Boedeker Ecological crisis... A few years ago, one could not even imagine that these words would be written about Lake Baikal, the deepest and purest lake in the world, which is now on the UNESCO World Heritage list. The first sign of the ecological crisis on Baikal was the rampant proliferation of the atypical filamentous Spirogyra alga. According to limnology scientists,...

Sustainable Development: A Lesson from Valentin Koptyug We Are Yet to Learn

... environmental protection was an area of constant concern for Koptyug. He consistently struggled against the project of Partial Flow Transfer of Northern and Siberian Rivers to the South, called attention to the problem of preserving freshwater in Lake Baikal, and organized other environmental initiatives. Having participated in the UN Conference on Environment and Development in Rio de Janeiro in 1992, he became an ardent supporter and propagandist of a new paradigm for sustainable development, being ...

The Ringed Baikal

In spring, from the height of “space observation” it is sometimes possible to see huge dark rings several kilometers in diameter in the ice of Lake Baikal. These unusual structures are not yet another mystery inked to extraterrestrials but a natural phenomenon, whose mechanism is being studied as part of an interdisciplinary project of the RAS Presidium The ice cover of Baikal attracted the attention ...

Insolation changes with Earth’s orbit shape (eccentricity) and with the tilt of the Earth’s rotation axis relative to its orbital plane (obliquity). Lake Baikal, with its continental interior position and long continuous deposition, stores a perfect undisturbed “archive” of Asian climates and is an exceptional paleoclimate site studied since 1990. During long and strong glaciations, the mountains ...

Among its most unusual inhabitants are freshwater sponges. Their first descriptions (Pallas, 1771; Georgi, 1775; Middendorf, 1867; Dybowski, 1880) made it clear that these animals ...

Weather Forecasting Back for 8 Million Years

Long sedimentary climate archives are common to the continuous oceanic deposition, but variable continental processes most often leave geographically dispersed records, which are often difficult to bring together. Baikal, the world deepest and oldest extant lake, represents a unique repository of events recorded on a long timescale and at high resolution and is thus a perfect natural laboratory to study continental paleoclimates, and especially the climate of Eurasia....
