NASA research offers new prospect of water on Mars
(PhysOrg.com) -- NASA scientists are seeing new evidence that suggests traces of water on Mars are under a thin varnish of iron oxide, or rust, similar to conditions found on desert rocks in California's Mojave ...
Study of gene expression in common blue-green algae reveals what makes it bloom, toxic
If your local pond, lake, or watering hole is looking bright green this summer, chances are it has blue-green algae and it may be dangerous to you or your pets. A newly published study has used a novel approach ...
Engineered bacteria make fuel from sunlight
Chemists at the University of California, Davis, have engineered blue-green algae to grow chemical precursors for fuels and plastics—the first step in replacing fossil fuels as raw materials for the chemical industry.
Team uncovers process for chameleon-like changes in world's most abundant phytoplankton
An international team of biologists led by Indiana University's David M. Kehoe has identified both the enzyme and molecular mechanism critical for controlling a chameleon-like process that allows one of the ...
Genetically engineered algae for biofuel pose potential risks that should be studied: ecologist
(Phys.org) -- Algae are high on the genetic engineering agenda as a potential source for biofuel, and they should be subjected to independent studies of any environmental risks that could be linked to cultivating algae for ...
Practical tool can 'take pulse' of blue-green algae status in lakes
Scientists have designed a screening tool that provides a fast, easy and relatively inexpensive way to predict levels of a specific toxin in lakes that are prone to blue-green algal blooms.
Shedding light on photosynthesis
(PhysOrg.com) -- Imagine being able to monitor protein expression levels in a cell as they change over time and in response to external stimuli. That is just what researchers did when they studied the photosynthetic ...
UT biosolar breakthrough promises cheap, easy green electricity
Barry D. Bruce, professor of biochemistry, cellular and molecular biology, at the University of Tennessee, Knoxville, is turning the term "power plant" on its head. The biochemist and a team of researchers have developed ...
Researchers model potential of toxic algae photoreceptors
Blue-green algae is causing havoc in Midwestern lakes saturated with agricultural run-off, but researchers in a northwest Ohio lab are using supercomputers to study a closely related strain of the toxic cyanobacteria ...
Getting to know bacteria with 'multiple personalities'
(PhysOrg.com) -- Cyanobacteria, or blue-green algae, have been the subject of decades of debate over exactly how they should be classified. While they reproduce and share DNA with their bacterial cousins, ...
Model helps pinpoint cyanobacterial genes that capture the sun's energy
A new computer model of blue-green algae can predict which of the organism's genes are central to capturing energy from sunlight and other critical processes.
Ancient bacterial mats may have been key to first mobile animals
New technique shows 50-year history of toxic algae in Lake Wingra
(PhysOrg.com) -- As public health officials worry about rising concentrations of cyanobacteria - often called blue-green algae - in lakes, scientists are concerned that a warming climate will stimulate the growth of cyanobacteria.
Making fuel from bacteria: Genetically-modified cyanobacteria could be more efficient than ethanol
In the search for the fuels of tomorrow, Swedish researchers are finding inspiration in the sea. Not in offshore oil wells, but in the water where blue-green algae thrive.
