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 existing morphological water structure deficiencies... view more... (2002-08-20)
Asleep or awake we retain memory
Sleeping helps to reinforce what we've learned. And brain scans have revealed that cerebral activity associated with learning new information is replayed during sleep. view more (2006-03-28)
UCSB researchers discover that the cell's endosomes use a surprising transportation system
Cells have developed a surprising transportation system for their endosomes, according to research published today in Physical Review Letters, "Dynamics and Spatial Organization of Endosomes in Mammalian Cells." view more (2005-10-06)

Professor Andrew Willmott has been appointed the next Director of the Proudman Oceanographic Laboratory in Liverpool. view more (2005-03-11)
Australia's climate: Drought and flooding in annual rings of tropical trees
Annual rings are acclaimed in representing natural climate archives. For the temperate latitudes it is known that the growth of these annual rings depend mainly on temperature and precipitation. view more (2009-06-12)
Models Simulate Nitrate Dynamics in Garonne, Southwest France
The over-enrichment of fresh, transitional, and marine waters with nitrogen (N) can lead to problems associated with eutrophication, such as a change in species composition of aquatic plants and nuisance algal blooms. In this context, dynamic models of flow and water quality are required to aid the implementation of the Water Framework Directive... view more... (2009-01-06)
The Value of Variation: Ecologists Consider the Causes and Consequences
Consider the case of the three-spine stickleback. These tiny fish that thrive in oceans and in fresh water might appear to be the same, yet ecologists are finding that they are actually a diverse collection of very specialized individuals. view more (2009-07-23)
Researchers measure field strength and density of ICF implosions
Scientists have identified for the first time two distinctly different types of electromagnetic configurations in inertial confinement fusion implosions that have substantial effects on implosion dynamics and diagnosis. view more (2008-02-29)
Environmental effects on genetic adaptation and population dynamics
It seems intuitive that genes are affected by selection as a result of environment. In fact there is little evidence thus far that such genetic effects impact year-to-year population dynamics. view more (2006-04-25)
More than 80% of patients manage to stop discomfort from tinnitus and can lead a normal life again
It is estimated that between 10 and 17% of the population has suffered tinnitus at some time in their lives, according to a number of international studies. view more (2007-06-26)
Nicotine exposure during development leads to hearing problems
Scientists know that children of women who smoke during pregnancy can develop hearing-related cognitive deficits. For the first time, researchers believe they have evidence that not only implicates nicotine as the culprit, but also shows what the substance does to the brain to cause these deficits. view more (2006-07-19)
Predators drive the lemming cycle in Greenland
A recent study conducted in eastern Greenland and published in the October 31 issue of the Science magazine provides new understanding of the dynamics of arctic lemming populations. Olivier Gilg and Ilkka Hanski from the University of Helsinki, Finland, and Beno'®t Sittler from the University of Freiburg, Germany, combined long-term field... view more... (2003-10-29)
Living Metals
Using synchrotron x-ray microbeams, a research team from the Max Planck Institute for Metals Research in Stuttgart and the ESRF has been able to observe for the first time that the microscopic structure of a crystalline material fluctuates in time. The results are published today in Science Express with the title: Scaling in the Time Domain:... view more... (2005-04-22)
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. Consequently the nitrogen lost from seagrasses is still... view more... (2008-05-23)
Visualizing atomic-scale acoustic wavesin nanostructures
Acoustic waves play many everyday roles - from communication between people to ultrasound imaging. Now the highest frequency acoustic waves in materials, with nearly atomic-scale wavelengths, promise to be useful probes of nanostructures such as LED lights. view more (2008-07-07)
Songbirds offer clues to highly practiced motor skills in humans
The melodious sound of a songbird may appear effortless, but his elocutions are actually the result of rigorous training undergone in youth and maintained throughout adulthood. His tune has virtually "crystallized" by maturity. view more (2007-12-27)
Williams Syndrome, the brain and music
Children with Williams syndrome, a rare genetic disorder, just love music and will spend hours listening to or making music. Despite averaging an IQ score of 60, many possess a great memory for songs, an uncanny sense of rhythm, and the kind of auditory acuity, than can discern differences between different vacuum cleaner brands. view more (2006-10-04)
Scientists find formula to uncover our planet's past and help predict its future
Studies of climate evolution and the ecology of past-times are often hampered by lost information - lost variables needed to complete the picture have been long thought untraceable but scientists have created a formula which will fill in the gaps of our knowledge and will help predict the future. view more (2009-05-27)
Researchers discover mechanism that determines when detailed memories are retained
The levels of a chemical released by the brain determine how detailed a memory will later be, according to researchers at UC Irvine. view more (2006-10-16)
MIT researcher sees big impact of little cracks
An MIT researcher's atom-by-atom simulation of cracks forming and spreading may help explain how materials fail in nanoscale devices, airplanes and even in the Earth itself during a quake. view more (2006-01-19)
