The Role Of Phytochromes In Bacteria Revealed
A research team jointly involving the IRD, the CEA and the CNRS has very recently found phytochromes in a strain of nitrogen-fixing bacterium, Bradyrhizobium (1), symbiont on certain tropical leguminous plants (the Aeschynomene). Techniques of molecular biology, biophysics and biochemistry revealed that the newly-discovered phytochrome has an... view more... (2002-05-13)
When light helps symbiont bacteria associate with plants to fix nitrogen
Certain leguminous plants which live in rice fields have the exceptional feature of forming nitrogen-fixing nodules on their stem surfaces. These contain symbiotic bacteria capable of using light as an energy source. Although it had been suspected that bacterial photosynthesis played a role in this highly particular nitrogen-fixing symbiosis,... view more... (2001-01-26)
Researchers successfully simulate photosynthesis and design a better leaf
University of Illinois researchers have built a better plant, one that produces more leaves and fruit without needing extra fertilizer. The researchers accomplished the feat using a computer model that mimics the process of evolution. Theirs is the first model to simulate every step of the photosynthetic process. view more (2007-11-12)
New twist on life's power source
A startling discovery by scientists at the Carnegie Institution puts a new twist on photosynthesis, arguably the most important biological process on Earth. view more (2008-03-12)
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)
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)
Counting semi-viable bacteria in cheese
The Wageningen researcher Christine Bunthof has developed a direct method for counting bacteria in dairy products. The method not only distinguishes viable and non-viable bacteria but also semi-viable bacteria. These are too weak to divide, but still exhibit activity. The semi-viable bacteria play an important role in cheese ripening and therefore... view more... (2002-05-23)
Sequences reveal benign origin of deadly plant pathogens
An international team of researchers has published the draft genome sequences of two deadly plant pathogens, Phytophthora ramorum and Phytophthora sojae. view more (2006-09-01)
Orientation of antenna protein in photosynthetic bacteria described
Researchers at Washington University in St. Louis have figured out the orientation of a protein in the antenna complex to its neighboring membrane in a photosynthetic bacterium, a key find in the process of energy transfer in photosynthesis. view more (2009-04-03)
Inner workings of photosynthesis revealed by powerful new laser technique
Instant pictures showing how the sun's energy moves inside plants have been taken for the first time, according to research out today (Friday 6 February) in Physical Review Letters. view more (2009-02-06)
Insects cultivate 'antibiotic-producing bacteria' in their antennae
Bacteria live in, on and around us and other organisms with sometimes very beneficial results. For the first time scientists have shown that one species of insect deliberately cultivates bacteria in its antennae in order to protect their larvae from fungal attack. view more (2007-04-02)
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)
A chunky metabolism
Many bacteria break their metabolic processes into chunks. That may be logically tidy, but it's often metabolically inefficient. Researchers have now figured out the factors that tend to make bacteria more modular. view more (2008-05-30)
The Rise of Oxygen Caused Earth's Earliest Ice Age
Geologists may have uncovered the answer to an age-old question - an ice-age-old question, that is. view more (2009-05-07)
'Jekyll and Hyde' bacteria offer pest control hope
New research at York has revealed so-called 'Jekyll and Hyde' bacteria, suggesting a novel way to control insect pests without using insecticides. view more (2007-12-20)
Dust storms may carry bacteria to Japan from China
Bacteria found in soil around Tokyo are not indigenous to the area. A study published in the open access journal Saline Systems reveals a large proportion of salt-loving bacteria in non-saline soil around Tokyo. The researchers suggest that dust storms may have carried the bacteria from their natural habitats in China. view more (2005-10-20)
Bacterial pathogens and rising temperatures threaten coral health
Coral reefs around the world are in serious trouble from pollution, over-fishing, climate change and more. The last thing they need is an infection. But that's exactly what yellow band disease (YBD) is-a bacterial infection that sickens coral colonies. view more (2009-01-20)
The structure of resistance
A team of scientists from the University Paris Descartes has solved the structure of two proteins that allow bacteria to gain resistance to multiple types of antibiotics, according to a report in EMBO reports this month. view more (2008-02-25)
How Bacteria get into Brains to Cause Meningitis
An international collaboration between medical researchers may have identified how meningitis causing bacteria cross from the blood into the brain, paving the way for new strategies to prevent this fatal disease, the Society for General Microbiology's Spring Meeting in Edinburgh heard today, Tuesday 8 April 2003. "Almost every known bacteria... view more... (2003-04-02)
Guidelines needed to prevent spread of infection in European hospitals
National and European guidelines to control the spread of vancomycin resistant enterococci should be drawn up before these bacteria become endemic in European hospitals, argue researchers in this week's BMJ. Vancomycin resistant bacteria have a low virulence but can cause serious infections in transplant patients or those in intensive care units.... view more... (2002-03-13)
