Environmental science flies higher and wider
A new and highly modified survey aircraft is the latest tool to help study our environment from the skies. The Natural Environment Research Council (NERC) is to lease a Dornier 228 to replace the Piper Navajo Chieftain that has given valiant service in earth observation for the past 16 years. Because the new aeroplane can fly further and carry... view more... (2000-07-25)
Microfossils challenge prevailing views of the effects of 'Snowball Earth' glaciations on life
New fossil findings discovered by scientists at UC Santa Barbara challenge prevailing views about the effects of "Snowball Earth" glaciations on life, according to an article in the June issue of the journal Nature Geoscience. view more (2009-05-27)
New group of algae discovered: Picobiliphytes
An international group of researchers has succeeded in identifying a previously unknown group of algae. As currently reported in the scientific journal Science, the newly discovered algae are found among the smallest members of photosynthetic plankton-the picoplankton ('Picobiliphytes: A marine picoplanktonic algal group with unknown affinities to... view more...

Cold climate produced by algae contributed to onset of multicellular life
The rise of multicellular animals about 540 million years ago was a turning point in the history of life. A group of Finnish scientists suggests a new climate-biosphere interaction mechanism for the underlying processes in a new study. view more (2007-02-14)
Dartmouth researchers alarmed by levels of mercury and arsenic in Chinese freshwater ecosystem
A team of researchers, led by biologists at Dartmouth, has found potentially dangerous levels of mercury and arsenic in Lake Baiyangdian, the largest lake in the North China Plain and a source of both food and drinking water for the people who live around it. view more (2008-01-10)
Changes in reef latitude
Since the 1980s, researchers have hypothesized that nutrient levels rather than temperature are the main factor controlling the latitudinal bounds of coral reefs, but the issue remains controversial. view more (2006-02-22)
Sinking Greenhouse Gases into the Ocean
"Polarstern" begins new iron fertilization experiment On January 21, 2004, the "Polarstern", research vessel of the Alfred-Wegener-Institute of Polar and Marine Research, will leave Cape Town for the third stage of the 21st expedition to Antarctica. Forty-nine scientists from nine countries will be aboard to investigate the effects of... view more... (2004-01-21)
Study links ecosystem changes in temperate lakes to climate warming
Unparalleled warming over the last few decades has triggered widespread ecosystem changes in many temperate North American and Western European lakes, say researchers at Queen's University and the Ontario Ministry of the Environment. view more (2008-12-17)
Synchronized swimming of algae
Using high-speed cinematography, scientists at Cambridge University have discovered that individual algal cells can regulate the beating of their flagella in and out of synchrony in a manner that controls their swimming trajectories. view more (2009-07-24)
Nitrogen fixation and phytoplankton blooms in the southwest Indian Ocean
Observations made by Southampton scientists help understand the massive blooms of microscopic marine algae - phytoplankton - in the seas around Madagascar and its effect on the biogeochemistry of the southwest Indian Ocean. view more (2009-08-17)
Researchers find key to saving the world's lakes
After completing one of the longest running experiments ever done on a lake, researchers from the University of Alberta, University of Minnesota and the Freshwater Institute, contend that nitrogen control, in which the European Union and many other jurisdictions around the world are investing millions of dollars, is not effective and in fact, may... view more...

Changing climate will lead to devastating loss of phosphorus from soil
Crop growth, drinking water and recreational water sports could all be adversely affected if predicted changes in rainfall patterns over the coming years prove true, according to research published this month in Biology and Fertility of Soils. view more (2009-04-15)
Antarctic expedition provides new insights into the role of the Southern Ocean for global climate
In the Southern Ocean, large quantities of surface-drifting plankton algae are able to significantly reduce the carbon dioxide content of the surface waters, which can affect the global carbon dioxide cycle. view more (2008-02-06)
MSU researcher finds renewed interest in turning algae into fuel
The same brown algae that cover rocks and cause anglers to slip while fly fishing contain oil that can be turned into diesel fuel, says a Montana State University microbiologist. view more (2008-01-16)
ORNL study finds rivers play part in removing nitrogen
Tiny organisms play a powerful role in removing nitrate, a form of nitrogen pollution caused by human activity, in streams, according to a study by a team led by Oak Ridge National Laboratory and published in Nature. view more (2008-03-13)
Underwater Microscope Helps Prevent Shellfish Poisoning Along Gulf Coast of Texas
Through the use of an automated, underwater cell analyzer developed at the Woods Hole Oceanographic Institution (WHOI), researchers and coastal managers were recently able to detect a bloom of harmful marine algae in the Gulf of Mexico and prevent human consumption of tainted shellfish. view more (2008-04-14)
Controlling algal blooms
Diatoms, highly successful photosynthetic plankton responsible for 40% of the net primary production in the oceans, undergo seasonal population explosions called phytoplankton blooms that attract billions of krill, copepods, and other grazing predators. view more (2006-02-21)
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)
Sunscreens from the sea
Tiny floating plants protect themselves against the damaging effects of the sun's ultra violet rays using compounds that may prove very useful to the skincare industry. Scientists at the Plymouth Marine Laboratory are now working with Boots Company plc to develop the potential of these natural sunscreens for human skincare. "Because... view more... (2001-07-18)
Understanding Phosphorus in Soils Is Vital to Proper Management
Phosphorus is one of the key nutrients that can cause algal blooms and related water quality problems in lakes, rivers, and estuaries worldwide. view more (2009-02-05)
