Bacterium present in eyes with 'wet' age-related macular degeneration
Researchers at the Massachusetts Eye and Ear Infirmary (MEEI) have found that Chlamydia pneumoniae, a bacterium linked to heart disease and capable of causing chronic inflammation, was present in the diseased eye tissue of five out of nine people with neovascular, or "wet," age-related macular degeneration (AMD). view more (2005-11-08)
The world`s most stable genome has been identified in aphid endosymbionts
Bacteria that reproduce inside aphids have not changed their genetic make-up for the last 50-70 million years. This makes the genomes of these bacteria the most stable of all organisms yet studied. This finding is presented by a team of scientists at Uppsala University, Sweden, in the latest issue of the scientific journal Science. Under the... view more... (2002-06-28)
The white stuff: Marine lab team seeks to understand coral bleaching
With technology similar to that used by physicians to perform magnetic resonance imaging (MRI) scans, researchers from six institutions-including the National Institute of Standards and Technology (NIST)-working at the Hollings Marine Laboratory (HML) in Charleston, S.C., are studying the metabolic activity of a pathogen shown to cause coral... view more...

Computer modeling could help chlorine-hungry bacteria break down toxic waste
Cornell researchers hope to learn how certain bacteria that break down pollutants do their job and then to make them more effective in cleaning up toxic wastes. view more (2007-06-21)
A step forward in the fight against bacterial infections
Bacterial infections can strike anyone, and they can sometimes be fatal. Because more and more bacteria are becoming resistant to the pre-eminent remedy; antibiotics; the search for new remedies against bacterial infections is in high gear. view more (2006-02-02)
ESC Congress 2004: New findings from ground-breaking PROVE IT-TIMI 22 clinical trial
Study Finds Antibiotics Do Not Prevent Heart Attacks view more (2004-08-30)
Computer-designed molecule to clean up fluorocarbons?
The chemical bond between carbon and fluorine is one of the strongest in nature, and has been both a blessing and a curse in the complex history of fluorocarbons. Now, in a powerful demonstration of the relatively new field of "computational chemistry". view more (2007-03-05)
E. coli engineered to produce important class of antibiotic, anti-cancer drugs
Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have taken a major step forward in the field of metabolic engineering, successfully using the bacterium Escherichia coli to synthesize a class of natural products known bacterial aromatic polyketides, which include important antibiotic and anticancer drugs. view more (2008-12-23)
Oldest animal fossils may have been bacteria
The oldest-known animal eggs and embryos, whose first pictures made the cover of Nature in 1998, were so small they looked like bugs - which, it now appears, they may have been. view more (2006-12-21)
E. coli playing the role of cobra
Moscow researchers have solved the most challenging problem: they made E. coli synthesize one of the most toxic elements of cobra's poison. It was no simpler a task than keeping a terrarium. The scientists' efforts were supported by the Russian Foundation for Basic Research and INTAS. Natural poisons have always been an attraction for researchers,... view more... (2004-05-07)
Scientists track chemical changes in cells as they endure extreme conditions
One of nature's most gripping feats of survival is now better understood. For the first time, scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory observed the chemical changes in individual cells that enable them to survive conditions that should kill them. view more (2009-07-08)
The complexities of genetic susceptibility to tuberculosis revealed
Researchers working in Vietnam have identified a genetic variant that predisposes people to developing a lethal form of tuberculosis (TB), tuberculous meningitis, if they are infected with a strain of TB known as the Beijing strain. view more (2008-03-28)
'Hellish' hot springs yield greenhouse gas-eating bug
A new species of bacteria discovered living in one of the most extreme environments on Earth could yield a tool in the fight against global warming. view more (2007-12-07)
Researchers identify genes for thiostrepton, a powerful drug whose use is now limited
Researchers at the Georgia Institute of Technology have identified the genetic machinery responsible for synthesizing thiostrepton, a powerful antibiotic produced by certain bacteria. Though effective against the dangerous MRSA (methicillin-resistant Staphylococcus aureus) and vancomycin-resistant enterococci, thiostrepton currently has only... view more... (2009-03-24)
Deep thinking: Scientists sequence a cold-loving marine microbe
At home in the deep, dark Arctic Ocean, the marine bacterium Colwellia psychrerythraea 34H keeps very cool-typically below 5° degrees Celsius. How does the bacterium function in this frigid environment? To find out, scientists at The Institute for Genomic Research (TIGR) and collaborators have sequenced and analyzed C. psychrerythraea's... view more... (2005-07-26)
In evolutionary arms race, a bacterium is found that outwits tomato plant's defenses, Cornell study finds
An arms race is under way in the plant world. It is an evolutionary battle in which plants are trying to beef up their defenses against the innovative strategies of pathogens. view more (2007-07-19)
MTBE contamination: A microbial approach for groundwater
Max Häggblom's Rutgers laboratory has taken an important step on the path to using microbes to rid the environment of methyl tertiary-butyl ether (MTBE), a toxic gasoline additive now classified as a potential human carcinogen. view more (2006-03-22)
Eating right, not supplements, is best at keeping your good bacteria healthy, dietitian says
Healthy eating, not supplements, is the best way to keep the good bacteria in your gut healthy, says a dietitian and researcher. view more (2009-10-22)
Thinking ahead: Bacteria anticipate coming changes in their environment
A new study by Princeton University researchers shows for the first time that bacteria don't just react to changes in their surroundings -- they anticipate and prepare for them. The findings, reported in the June 6 issue of Science, challenge the prevailing notion that only organisms with complex nervous systems have this ability. view more (2008-06-19)
One secret to how TB sticks with you
Mycobacterium tuberculosis is arguably the world's most successful infectious agent because it knows how to avoid elimination by slowing its own growth to a crawl. view more (2009-07-10)
