Mathematicians from Novosibirsk and Krasnoyarsk, working on a joint project with American colleagues (sponsored by the CRDF and the Federal Agency for Science and Innovations (Rosnauka)) have improved the tsunami forecasting system. To this end, they applied the method of the so-called circulation of tsunami data obtained in a real-time mode. This newest method is based on the latest results achieved by researchers in the theory and numerical algorithms of inverse problem solution.

In vast remote taiga not far from the Yenisei river, where one can get only by helicopter within one third of the year, the construction of a huge 300-meter high mast is to be completed this summer. In the underground shelter under the mast, a research laboratory will be located, which is stuffed with the most contemporary scientific equipment. Researchers needed that in order to thoroughly investigate who or, more precisely, what is responsible for the greenhouse effect, where oxygen, carbonic ac
New scientific results for the Late Cretaceous greenhouse indicate radically different climatic mechanisms operating about 75-90 million years ago compared to the ones that control today’s climate. The study, published on 29 May 2006 in “Palaeogeography, Palaeoclimatology, Palaeoecology” as part of a special issue on “Causes and Consequence of Marine Organic Carbon Burial Through Time” by Sascha Floegel from the IFM-GEOMAR in Kiel/Germany and Thomas Wagner from the University of Newcastle upon
First assessment in two years points to widespread poaching
Results released today by World Wildlife Fund of the first assessment done in two years in one of Nepal’s premier national parks reveal an alarming decline in tiger and rhino populations, indicating widespread poaching. The area only became accessible for visits since the ceasefire between the Maoist insurgents and government troops a month ago.
Since 1986, 70 rhinos were translocated to Bardia National P
Prairie plants may also be good source of biofuel
Ecosystems containing many different plant species are not only more productive, they are better able to withstand and recover from climate extremes, pests and disease over long periods, according to a new study. It is the first experiment to gather enough data–over a sufficient time and in a controlled environment–to confirm a 50-year scientific debate about whether biodiversity stabilizes ecosystems.
The findings,
Ecosystems containing many different plant species are not only more productive, they are also better able to withstand and recover from climate extremes, pests and disease over long periods of time.
These findings, published in the June 1 issue of Nature, are the culmination of 12 years of experiments conducted by David Tilman, Regents Professor of Ecology at the University of Minnesota, to explore the value of biodiversity. The research was carried out at Cedar Creek Natural H
Comfortable living is not why so many different life forms seem to converge at the warmer areas of the planet.
Writing this week in the Proceedings of the National Academy of Sciences, scientists say higher temperatures near the equator speed up the metabolisms of the inhabitants, fueling genetic changes that actually lead to the creation of new species.
The finding – by researchers from the University of Florida, the National Center for Ecological Analysis and Synthesis
Unique Underground Ecosystem Revealed by Hebrew University
Discovery of eight previously unknown, ancient animal species within “a new and unique underground ecosystem” in Israel was revealed today by Hebrew University of Jerusalem researchers.
In a press conference on the Mt. Scopus campus of the Hebrew University, the researchers said the discovery came about when a small opening was found, leading to a cave extending to a depth of 100 meters beneath the surface
With world energy prices and climate-altering greenhouse gas emissions ballooning in tandem with a surge in energy demand from the hot economies of China, India and Brazil, the world has a major stake in the success of energy reduction efforts, particularly in those three countries, warn experts concluding a four-year international project.
Without significant gains from energy efficiency efforts, China, India and Brazil within a single human generation (by 2030) will more than
Kelp forest ecosystems that span the West Coast –– from Alaska to Mexico’s Baja Peninsula –– are at greater risk from overfishing than from the effects of run-off from fertilizers or sewage on the shore, say scientists at the University of California, Santa Barbara. The findings have important implications for the design of California’s Marine Protected Areas.
In an article published in the May 26 issue of Science, scientists describe the first study to compare the top-down ver

When most people think of Louisiana as being unique, they think of Mardi Gras, crawfish and Cajun culture. Few realize that what lies beneath the Gulf of Mexico along Louisiana’s coast is also unique, from the terrain and habitat to the animals living there. And two LSU researchers are diving down some 3,000 meters to explore it.
Researchers Harry Roberts and Bob Carney are combing the most unique continenta
A new tree-ring-based reconstruction of 508 years of Colorado River streamflow confirms that droughts more severe than the 2000-2004 drought occurred before stream gages were installed on the river.
The new research also confirms that using stream gage records alone may overestimate the average amount of water in the river because the last 100-year period was wetter than the average for the last five centuries.
“This work updates the original landmark Colorado River re
Selfishness is not necessarily the best survival trait for microorganisms, according to researchers studying the comparative effectiveness of ‘cheating’ and ‘cooperating’ strains of yeast.
Writing in the journal Nature today, the team reports that studies of lab-grown yeast populations suggest the benefits of cheating are eventually counterbalanced by the costs. This contradicts classic evolutionary theory, which states that in a competition for common resources the long-term win
For a decade now, ESA satellites have been continuously surveying fires burning across the Earth’s surface. Worldwide fire maps based on this data are now available to users online in near real time through ESA’s ATSR World Fire Atlas.
The ATSR World Fire Atlas (WFA) – the first multi-year global fire atlas ever developed – provides data approximately six hours after acquisition and represents an important scientific resource because fire is a major agent of environmental change.
Mystery is surrounding the huge declines of birds that migrate thousands of miles from Africa to the UK and Europe each spring.
Scientists fear that their dwindling numbers – well over 50 per cent down in some cases – may be a warning of widespread environmental damage, which could soon affect man as well.
Climate change, drought and desertification in Africa, and massive pesticide use on African farmland may all be to blame for the declines of once common UK birds such
With recent announcements of potential impending water shortages, everyone is being urged to do their bit to avert further draconian measures. Yet, according to OFWAT, the government’s water industry regulator, less than 30 percent of households in the UK have metered water supply. The other seventy percent can use as much water as they want, with few limits in a normal year and not that many at the moment given the current drought. So is it time for universal water metering?
