Desert dust enables algae to grow
Biologists from the Royal Netherlands Institute for Sea Research have demonstrated that desert dust promotes the growth of algae. Scientists had already assumed that the iron in desert dust stimulated algal growth, but this has now been demonstrated for the first time. The researchers have published their findings in the December issue of the... view more... (2003-12-19)
Researcher turns brown algae phylogeny upside down
According to fellow phycologists, algae expert Stefan Draisma from the Leiden University has turned brown algae phylogeny completely upside down. His research shows that few of the currently assumed relationships between the orders are correct. Furthermore, it transpires that some simple species arose not earlier but later than more complex... view more... (2002-06-24)
The secret life of algae
The researchers, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), found that no algae have the necessary genes to produce vitamin B12. view more (2006-01-12)
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...

Eutrophication affects diversity of algae
Eutrophication of the seas may have an impact on genetic variation in algae, research at the University of Gothenburg shows. view more (2009-10-20)
Algae understand the language of bacteria
It has hitherto not been known that higher organisms, such as green algae, can communicate with bacteria. But Debra Milton, associate professor at Ume'å University in Sweden, shows in the recent issue of the prominent journal Science that bacteria attract green algae with the aid of signal molecules. Surfaces under water are rapidly... view more... (2002-11-12)
Europe's largest climate change experiment launched
Scientists at the University of Liverpool have launched a large scale experiment to monitor the impact of climate change on freshwater systems. view more (2006-01-18)
Killer algae a key player in mass extinctions
Supervolcanoes and cosmic impacts get all the terrible glory for causing mass extinctions, but a new theory suggests lowly algae may be the killer behind the world's great species annihilations. view more (2009-10-20)
Coralline algae in the Mediterranean lost their tropical element between 5 and 7 million years ago
An international team of researchers has studied the coralline algae fossils that lived on the last coral reefs of the Mediterranean Sea between 7.24 and 5.3 million years ago. view more (2009-07-07)
A thirst for blood sparks toxic algal blooms
The blooming of toxic algae that occurs during the summer conceal a fight for life and death. Scientists at the University of Gothenburg propose in an article published in the journal PNAS that algal blooms are created when aggressive algae kill and injure their competitors in order to absorb the nutrients they contain. view more (2009-06-30)
Chemical Cudgel in Plants
Defense mechanisms of single-celled algae Plankton are at the bottom of the food chain in all natural bodies of water and are thus correspondingly important for their ecological balance. In the cycle of eating and being eaten it isn't only fish and whales that prey on these tiny animals and plants - they also eat each other. For example, a variety... view more... (2000-11-29)
Engineering algae to make fuel instead of sugar
In pursuing cleaner energy there is such a thing as being too green. Unicellular microalgae, for instance, can be considered too green. view more (2008-12-17)
Billion-year revision of plant evolution timeline may stem from discovery of lignin in seaweed
Land plants' ability to sprout upward through the air, unsupported except by their own woody tissues, has long been considered one of the characteristics separating them from aquatic plants, which rely on water to support them. view more (2009-01-27)
Virus decimates algal blooms
As soon as the pest algae run out of nutrients, viruses attack and abruptly end the algal bloom. This is revealed in a three-year international study under the leadership of the Netherlands Institute for Sea Research. This knowledge opens up opportunities for using natural enemies to remove algal blooms in isolated areas. The pest alga species... view more... (2002-11-15)
New service to help monitor toxic species in marine waters
University of Liverpool scientists have launched a new website to help environmental agencies and marine industries identify harmful organisms in UK coastal waters. view more (2006-01-25)
Algae could one day be major hydrogen fuel source
As gas prices continue to soar to record highs, motorists are crying out for an alternative that won't cramp their pocketbooks. view more (2008-04-02)
Even seaweeds get sunburned
It is red, it burns and itches: a sunburn on our skin. However, too much sun is not only bad for humans. Many plants react sensitively to an increased dose of ultraviolet radiation, too. Yet they are dependent on sunlight. view more (2008-08-25)
Microscope to aid shell-fishing industry
Groundbreaking research by University of Plymouth experts into the detection of harmful species of algae has helped develop a unique microscope, which could dramatically decrease cases of poisoning from contaminated shellfish. The HAB (harmful algae blooms)-Buoy is an innovative project, funded by the European Union, involving Dr Phil Culverhouse,... view more... (2003-05-29)
Harvesting Arctic algae
Microorganisms living in the depths of the oceans under conditions unbearable for humans utilize hot springs to produce their energy and substances. Some bacteria and algae feel right at home in the boiling waters of a geyser and others in acid ponds or salt waters. Still others populate glaciers and snow fields. For many years, researchers have... view more... (2002-09-20)
Piecing together the cyanobacteria puzzle
Blue green algae are significant species in the global carbon cycle because they transform nitrogen gas from the atmosphere into a useable nutrient, enabling photosynthesis in nutrient-poor waters. view more (2007-07-11)
