The dominant causes are the many stressors that affect lakes, rivers and wetlands globally: habitat loss, over-fishing, invasions by alien species, dams, over-abstraction, many forms of pollution and increasing salinity.
Fresh waters are also highly sensitive to climate change which now exacerbates all these other problems. With the sustainability of the biosphere and the needs of billions of people at risk, there is an urgent scientific challenge to understand the problems and seek long-term solutions.
Now, to initiate a series of scientific ‘summits’, some of the world’s leading freshwater scientists will meet at the Freshwater Biological Association’s (FBA) HQ on the shore of Windermere 1-4 September. The agenda is to consolidate evidence, raise awareness, launch an international call for action and influence those with responsibility for safeguarding the future of global fresh waters.
The meeting will be opened by Professor John Beddington, Chief Scientific Advisor to the UK Government, who will outline the importance of freshwater ecosystems in a changing world. "I'm delighted to be speaking at such a worthwhile conference which highlights the importance of freshwater ecosystems, such as rivers and lakes and the impact our activities have on them. We need to recognise the pressures that are placed on our freshwater resources.
Pressures such as population increases, a changing climate, urbanisation, food production and fishing are interlinked and in many cases will collectively threaten vital freshwater resources”, commented Professor Beddington. “It is not all doom and gloom however, I believe science and technology can play a key role in responding to these challenges, and this conference will be an important contribution to our understanding and mitigation of such issues."
Presentations will be given by speakers from Australia, New Zealand, the United States, Canada and Europe.
This is a truly global issue. By bringing together leading experts from all over the world the FBA intends that the shared knowledge will lead to a clearer understanding of the consequences of the many different pressures being placed on key freshwater resources. The outcome of the meeting will be a position statement, endorsed by all the speakers, outlining the current state of scientific knowledge and identifying what action is needed to improve knowledge, understanding, policy and management strategies.

Nanoparticles help with malaria diagnosis – new rapid test in development
21.11.2017 | Fraunhofer-Institut für Silicatforschung ISC
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,...
