New river basin classification will help safeguard region's biodiversity and monitor infrastructure development
Scientists from WCS (Wildlife Conservation Society), The Nature Conservancy, and several partners in Brazil and Peru have produced a geographic information system (GIS) "roadmap" to help guide conservation efforts at large scale in the Amazon River basin, a region roughly the size of the United States.

The new spatial framework--created with several major data sets and GIS technology -- is made up of a new hydrological and river basin classification, along with various spatial analysis tools, that can be used to better understand and mitigate the synergistic effects of deforestation and new or planned highways and dams across the Amazon Basin.
The paper titled "An explicit GIS-based river basin framework for aquatic ecosystem conservation in the Amazon" appears in the most recent edition of the journal Earth System Science Data. The authors are: Eduardo Venticinque of Universidade Federal do Rio Grande do Norte; Bruce Forsberg of the Instituto Nacional de Pesquisas da Amazônia; Ronaldo B. Barthem of the Museu Paraense Emilio Goeldi; Paulo Petry of The Nature Conservancy; Laura Hess of the Earth Research Institute; Armando Mercado, Carlos Cañas, Mariana Montoya, Carlos Durigan, and Michael Goulding of WCS.

"The new spatial framework provides a dynamic way to map natural resources and possible infrastructure impacts on them at various scalable levels in the Amazon, one prime example being fisheries and fish migrations and the far-flung wetlands that support them," said Eduardo Venticinque of Universidade Federal do Rio Grande do Norte, the lead author of the study.
"This new tool will enable scientists and governments to monitor development initiatives across the Amazon basin and help guide policy to minimize the environmental impact of these activities," said WCS scientist Michael Goulding.
The Amazon is home to the most biodiverse rainforest on Earth, as well as the greatest freshwater system in the world. The region also supports what is likely the largest assemblage of wetlands in the world, a mosaic that ranges from seasonally flooded forests that cover most of the floodplains to immense savannas inundated for many months each year. The region is also considering a number of infrastructure development projects that could significantly impact the hydrology of the Amazon Basin and its fauna and flora. Conservation efforts typically focus on creating and strengthening protected areas and indigenous territories in the Amazon, with little focus on the aquatic systems. The new framework will help focus conservation and management efforts on waters and wetlands and the important resources they contain, including more than 2,400 species of fish, to promote a more integrated and large-scale approach to protecting the Amazon Basin.
In order to create a river basin classification system--one that could be used to serve the needs of conservation and monitoring--the scientists divided the river basin into a number of sub-basins defined by 11 different stream orders ranging from tiny streams to the Amazon River itself. Seven distinct levels of basins were defined, with the main Amazon Basin as Level 1, and larger tributary sub-basins such as the Ucayali and the Madeira as Level 2, and so on.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
