Cyanobacteria ("blue-green algae") produce toxin with possible connection to neurodegerative disorders
It is well known that a tiny number of cyanobacteria, previously known as blue-green algae, produce substances that can be toxic to both humans and animals. Now a research team from Sweden, Scotland, and the U.S. has found that a further toxin (BMAA, -methyl amino-alanine) with a possible connection to degenerative nerve diseases like ALS,... view more...

Microbes use sunscreens too
Microbes can withstand extreme levels of atmospheric ultraviolet light (UV) by producing their own sunscreens. Unlike humans, some bugs may even be able to survive without any help from the ozone layer scientists heard today (Thursday 19 September) at the Society for General Microbiology autumn meeting at Loughborough University. "A group of... view more... (2002-08-28)
Blue-Green Algal Links to Alzheimer's-Like Neurological Disease
An international team of researchers, including scientists from the University of Dundee have announced that cyanobacteria (blue-green algae) found throughout the world may produce a toxin linked to certain types of neurological disease. view more (2005-04-05)
Surf's up - and one coastal microbe has adapted
California beachgoers may look lazy. But just a few miles off shore, scientists have discovered that a common coastal strain of cyanobacteria works diligently to thrive in choppy, polluted waters. view more (2006-08-29)
New source for biofuels discovered
A newly created microbe produces cellulose that can be turned into ethanol and other biofuels, report scientists from The University of Texas at Austin who say the microbe could provide a significant portion of the nation's transportation fuel if production can be scaled up. view more (2008-04-24)
Saharan dust storms sustain life in Atlantic Ocean
Research at the University of Liverpool has found how Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean. view more (2008-07-21)
Bioclocks work by controlling chromosome coiling
In recent years, scientists have discovered that biological clocks help organize a dizzying array of biochemical processes in the body. Despite a number of hypotheses, exactly how the microscopic pacemakers in every cell in the body exert such a widespread influence has remained a mystery. view more (2007-11-26)
Did death-dealing cyanobacteria cause the mass deaths of Messel?
In 1875 the remains of a prehistoric crocodile were found in the brown coal mine at Messel near Darmstadt; since then a large number of well preserved fossils have also been discovered. Palaeontologists have long puzzled over what could have been the reason for this annihilation of so many creatures. In the latest issue of the Pal'¤ontologische... view more... (2004-11-17)
Future for clean energy lies in 'big bang' of evolution
Amid mounting agreement that future clean, "carbon-neutral", energy will rely on efficient conversion of the sun's light energy into fuels and electric power, attention is focusing on one of the most ancient groups of organism, the cyanobacteria. view more (2008-08-25)
Freeze-dried mats of microbes awaken in Antarctic streambed, says U. of Colorado study
An experiment in a dry Antarctic stream channel has shown that a carpet of freeze-dried microbes that lay dormant for two decades sprang to life one day after water was diverted into it, said a University of Colorado at Boulder researcher. view more (2005-08-10)
Natural compound from 'pond scum' shows potential activity against Alzheimer's
A compound isolated from a cyanobacterium, a type of blue-green algae known as Nostoc, shows promise of becoming a natural drug candidate for fighting Alzheimer's and other neurodegenerative diseases. view more (2005-12-29)
UCSD research team identifies novel anticancer drug from the sea
A collaborative team of researchers spearheaded by Dennis Carson M.D., professor of medicine and director of the Rebecca and John Moores UCSD Cancer Center at the University of California, San Diego (UCSD) has identified a potent new anti-cancer drug isolated from a toxic blue-green algae found in the South Pacific. view more (2008-02-12)
Study shows our ancestors survived 'Snowball Earth'
It has been 2.3 billion years since Earth's atmosphere became infused with enough oxygen to support life as we know it. About the same time, the planet became encased in ice that some scientists speculate was more than a half-mile deep. view more (2006-06-07)
Researchers find cancer-inhibiting compound under the sea
University of Florida College of Pharmacy researchers have discovered a marine compound off the coast of Key Largo that inhibits cancer cell growth in laboratory tests, a finding they hope will fuel the development of new drugs to better battle the disease. view more (2008-08-11)
Scientists find key to ocean bacterium that helps control greenhouse gas
Scientists are a step closer to understanding how the world's oceans influence global warming - as well supply us with the oxygen we breathe. A study led by Imperial College London has revealed how the most abundant ocean bound photosynthetic bacterium helps control levels of the greenhouse gas, carbon dioxide. Reporting in Nature the researchers... view more... (2003-08-27)
Learning to live with oxygen on early Earth
Washington, D.C. Scientists at the Carnegie Institution and Penn State University have discovered evidence showing that microbes adapted to living with oxygen 2.72 billion years ago, at least 300 million years before the rise of oxygen in the atmosphere. view more (2006-10-17)
Great Lake's sinkholes host exotic ecosystems
Researchers are exploring extreme conditions for life in a place not known for extremes. As little as 20 meters (66 feet) below the surface of Lake Huron, the third largest of North America's Great Lakes, peculiar geological formations-sinkholes made by water dissolving parts of an ancient underlying seabed-harbor bizarre ecosystems where the fish... view more...

Out of the blue"¦press conference invitation
Deep-sea microbiology could soon be helping to restrain antibiotic-resistant infections like MRSA, the hospital 'superbug', according to research results to be announced at a conference in Edinburgh on Tuesday 24 May. view more (2005-05-18)
Novel bacterial strains clear algal toxins from drinking water
Novel bacterial strains capable of neutralizing toxins produced by blue-green algae have been identified by researchers at Robert Gordon's University, Aberdeen. view more (2009-09-08)
