Increased environmental carbon levels - the good news!
Increasing carbon levels can be a good thing in some cases: scientists at the University of Durham propose that higher levels of inorganic carbon can have a positive influence on human health. view more (2006-04-03)
Are microbes the answer to the energy crisis?
The answer to the looming fuel crisis in the 21st century may be found by thinking small, microscopic in fact. Microscopic organisms from bacteria and cyanobacteria, to fungi to microalgae, are biological factories that are proving to efficient sources of inexpensive, environmentally friendly biofuels that can serve as alternatives to oil,... view more...

Laser technique has implications for detecting microbial life forms in Martian ice
An innovative technique called L.I.F.E. imaging used successfully to detect bacteria in frozen Antarctic lakes could have exciting implications for demonstrating signs of life in the polar regions of Mars. view more (2009-10-02)
The 'oxygen imperative'
It's common knowledge that humans and other animals couldn't survive without oxygen. But scientists are now learning a good deal more about the extent of our evolutionary debt to a substance that was once a deadly poison. view more (2006-03-24)
Discovering the secret code behind photosynthesis
Scientists from Queen Mary, University of London have discovered that an ancient system of communication found in primitive bacteria, may also explain how plants and algae control the process of photosynthesis. view more (2009-02-25)
Biologists surprised to find parochial bacterial viruses
Biologists examining ecosystems similar to those that existed on Earth more than 3 billion years ago have made a surprising discovery: Viruses that infect bacteria are sometimes parochial and unrelated to their counterparts in other regions of the globe. view more (2008-03-05)
A new day dawned fast
In 1980, Luis Alvarez and his collaborators stunned the world with their discovery that an asteroid impact 65 million years ago probably killed off the dinosaurs and much of the the world's living organisms. But ever since, there has been an ongoing debate about how long it took for life to return to the devastated planet and for ecosystems to... view more... (2009-10-05)
Green algae -- the nexus of plant/animal ancestry
Genes of a tiny, single-celled green alga called Chlamydomonas reinhardtii may contain scores more data about the common ancestry of plants and animals than the richest paleontological dig. view more (2007-10-12)
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)
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)
Microbialities: Indicators Of Environmental And Climatic Changes?
Microbial communities can adapt to and colonize all kinds of habitat, owing to their metabolic versatility. They occur in abyssal oceanic situations, in polar ice caps, also in thermal springs, lakes, rivers, deserts and on carbonate (karst) platform systems. Under favourable conditions, the microbial communities can proliferate and contribute to... view more... (2002-09-27)
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)
Algal biomonitor
A paper published in the current issue of the International Journal of Environment and Pollution, explains how a DNA test can be used to detect harmful algal blooms across the globe. view more (2008-10-01)
Researchers visualize complex pigment mixtures in living cells
In a technical advance that could allow researchers to watch cells as they act during the process of photosynthesis, scientists have developed a method that extends the power of fluorescence-mediated bio-imaging to see discrete pigments inside live cells of bacteria. view more (2008-03-05)
Researchers sequence the basal eukaryote Tetrahymena thermophila
In an effort to improve our understanding of eukaryotic evolution, a team of over 50 researchers led by Jonathan Eisen sequenced the macronuclear genome of the single-celled ciliate Tetrahymena themophila. view more (2006-08-29)
Origins of Life
The origin of life lies in unique ocean reefs, and scientists from the University of Miami's Rosenstiel School of Marine & Atmospheric Science have developed an approach to help investigate them better. view more (2006-11-20)
Green Plants Share Bacterial Toxin
A toxin that can make bacterial infections turn deadly is also found in higher plants, researchers at UC Davis, the Marine Biology Laboratory at Woods Hole, Mass. view more (2006-11-07)
Fuel from food waste: bacteria provide power
Researchers have combined the efforts of two kinds of bacteria to produce hydrogen in a bioreactor, with the product from one providing food for the other. view more (2008-07-17)
New research network: Artificial photosynthesis för future energy producion
Nature utilizes energy from the sun for its production. Some algae produce hydrogen from water with the help of solar energy. So why not imitate nature to extract renewable energy without harming the environment? The EU is now giving European research a boost by allocating EUR1.8 million to a new network to be led by Uppsala University. Plant... view more... (2005-02-21)
PLoS Biology: Neural Activity Reveals Continuity Between Infant and Adult Sleep; Virus-host Interactions at Sea Effect Global Photosynthesis
Infant Sleep: A Precursor to Adult Sleep? Sleep is absolutely essential for well-being. Just ask one of the 40 million Americans with sleep disorders who suffer crippling fatigue, impaired judgment, irritability, moodiness, and myriad health problems. Still, its precise function remains unclear. An intriguing role for REM sleep - the stage most... view more... (2005-04-12)
