Renaturation of waterbodies does not have to be expensive
The water landscape in many countries has many deficiencies. The ecological consequences of this are poor water quality as well as a deterioration and a shift of the naturally occurring species spectrum. The Fraunhofer Institute for Systems and Innovation Research ISI, Germany, has examined the... view more (2002-08-20)

Medicalising sex damages relationships
Overly medical approaches to sex ignore the social and interpersonal dynamics of relationships, argue researchers in this week's BMJ. The medicalisation of sex has resulted in surgery and drugs being used to enhance sexual pleasure, write Graham Hart and Kaye Wellings. Viagra (sildenafil citrate)... view more (2002-04-10)

Microtubule protein interactions visualized en masse
In a new study published online in the open access journal PLoS Biology, Philipp Niethammer, Eric Karsenti, and colleagues investigate the regulation of microtubule dynamics via application of their new method, called visual immunoprecipitation (VIP), which enables simultaneous visualization of... view more (2007-01-16)

The Mediterranean connection: ecological effects of El Ni'±o in the Northern hemisphere
The North Atlantic Oscillation (NAO) and the El Ni'±o/Southern Oscillation (ENSO) are being increasingly acknowledged as major climatic sources of ecological variability. However, studies linking ecological processes to those oscillations have been conducted in geographic regions close to their... view more (2004-06-10)

Are existing large-scale simulations of water dynamics wrong?
Soils are complicated porous media that are highly relevant for the sustainable use of water resources.   view more (2008-03-11)

New surprising results about the research on glaciers
In order to understand the dynamics of glaciers and ice sheets as well as their interactions with climate, we need fundamental detailed knowledge about the way in which glaciers and ice sheets move. The way water is routed through glaciers is highly significant for their movement since the water... view more (2005-02-09)

Telling axons where to go - and grow
In a recent study, Dr. Ingolf Bach and colleagues from the University of Massachusetts Medical School, Worcester and the University of Hamburg (Germany) describe a novel role for the ubiquitin/proteosome protein degradation pathway in the regulation of local actin dynamics in neurons.   view more (2005-10-03)

Floating lovers count too — in the health of eagle populations
In a paper from the November issue of The American Naturalist, Vincenzo Penteriani, Fermín Otalora, and Miguel Ferrer, researchers at the Estación Biológica de Doñana (Consejo Superior de Investigaciones Científicas, Spain), focus on the forgotten and invisible side of animal populations-the... view more (2006-11-02)

The memory lingers longer
PCBs and dieldrin, for example, now banned for further industrial and agricultural use, are simply not breaking down in the environment as speedily as needed to meet environmental targets. Catchments of rivers in west Yorkshire with a long history of contamination by chemicals used in the... view more (1999-12-22)

Nitrogen retained through loss
The nitrogen cycle plays a major role in seagrass fields. Dutch researcher Arie Vonk studied the nitrogen dynamics of seagrasses in Indonesia. He discovered that the interaction between seagrasses, animals and microorganisms results in an efficient nitrogen cycle in tropical seagrass fields.... view more (2008-05-23)

'Micro-boxes' of water used to study single molecules
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated the use of water droplets as minuscule "boxes" for small numbers of biomolecules.   view more (2006-07-24)

Simulations help explain fast water transport in nanotubes
By discovering the physical mechanism behind the rapid transport of water in carbon nanotubes, scientists at the University of Illinois have moved a step closer to ultra-efficient, next-generation nanofluidic devices for drug delivery, water purification and nano-manufacturing.    view more (2008-09-17)

The short-term memory of water
Researchers of the Max-Born-Institute and the University of Toronto find extremely fast fluctuations in liquid water - Publication in Nature.   view more (2005-03-07)

Local interventions have little effect on metapopulation stability
Stabilizing fluctuations in the number of individuals in fragmented populations of threatened species is an important concern in conservation biology.   view more (2007-02-21)

Loss of Hemlocks Will Affect Water Dynamics in Southern Appalachian Forests
Forest Service (FS) research has provided the first estimates on the impact the loss of eastern hemlock will have on the water dynamics of the southern Appalachian mountains.   view more (2007-07-10)

Balancing Use to Fill Today`s Gaps and Meet Tomorrow`s Needs: Water for People, Food and Environment Stockholm Water Symposium in August is last major global water forum before UN development summit in South Africa
To feed the planet`s 8 billion inhabitants in 2025, the world will need as much extra water simply for food production as is currently in use for - but not yet satisfying - our drinking, sanitation, industrial and irrigation needs. From where will this new water come? That question will be... view more (2002-08-06)

Research advances understanding of how hydrogen fuel is made
Oxygen may be necessary for life, but it sure gets in the way of making hydrogen fuel cheaply and abundantly from a family of enzymes present in many microorganisms.   view more (2005-10-06)

Quantum mechanics predicts unusual lattice dynamics of vanadium metal under high pressure
A Swedish research team of Dr. Wei Luo & Professor Rajeev Ahuja and US team of Dr. Y. Ding & Prof. H.K. Mao have used theoretical calculations to understand a totally new type of high-pressure structural phase transition in Vanadium.   view more (2007-10-12)

A better understanding of equatorial Atlantic deep currents
One of the main components of the Atlantic's water-mass circulation is a cold water flow (at 4°C on average) -the North Atlantic Deep Water (NADW)- which is conveyed at depth (between 1500 and 4000 m), sweeping from the Labrador Sea, Norway and Greenland in the polar and sub-polar zones towards... view more (2001-04-26)

Studying rivers for clues to global carbon cycle
In the science world, in the media, and recently, in our daily lives, the debate continues over how carbon in the atmosphere is affecting global climate change. Studying just how carbon cycles throughout the Earth is an enormous challenge, but one Northwestern University professor is doing his part... view more (2008-02-11)

Alaska glacier speed-up tied to internal plumbing issues, says CU-Boulder study
A University of Colorado at Boulder study indicates meltwater periodically overwhelms the interior drainpipes of Alaska's Kennicott Glacier and causes it to lurch forward, similar to processes that may help explain the acceleration of glaciers observed recently on the Greenland ice sheet that are... view more (2008-01-16)

2002 Stockholm Water Prize Winner Announcement
The recipient of the 2002 Stockholm Water Prize, the leading international award for outstanding achievements on behalf of the world's water, will be announced in Stockholm on March 22 in a press conference at 11.00, Central European Time. The $150,000 Stockholm Water Prize is being presented by... view more (2002-02-04)

Getting to the Root of the Matter
Like most things that exist underground, plant roots are out-of-sight and easily forgotten, but while flowers, leaves, and other aboveground plant parts are more familiar, plant roots are equally deserving of our appreciation. Beneath every towering tree, tasty crop, and dazzling ornamental lies a... view more (2008-08-20)

Study finds key distinction between outbreaks that die out and epidemics
In an important study forthcoming in the March 2006 issue of the American Naturalist, biologists from Yale University, University of Florida, and Dartmouth University explore the dynamics of pathogen survival and shed new light on a longstanding mystery: why some infectious diseases are limited to... view more (2006-02-22)
