2014-07-07 04:50:26

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Technical University of Denmark (DTU) have discovered 500 previously unidentified microorganisms in human intestinal flora, as well as 800 new types of viruses that attack intestinal bacteria. In addition, DTU Systems Biology professor Søren Brunak, associate professor Henrik Bjørn Nielsen and their colleagues devised a new principle for analyzing DNA sequence data in order to map the newly discovered...

American Society for Microbiology Scientists believe they have an explanation for the axiom that stress, emotional shock, or overexertion may trigger heart attacks in vulnerable people. Hormones released during these events appear to cause bacterial biofilms on arterial walls to disperse, allowing plaque deposits to rupture into the bloodstream, according to research published in published today in mBio®, the online open-access journal of the American Society for Microbiology. "Our...

Irvine, California (PRWEB) May 22, 2014 Microbial communities thrive in diverse niches under different conditions where they can elicit a strong influence on their...

Unseen Armies Of Viruses And Bacteria Battle In The Deep
2014-05-02 03:58:44

National Science Foundation More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war. Like pirates boarding a treasure-laden ship, the viruses infect bacterial cells to get the loot: tiny globules of elemental sulfur stored inside the bacterial cells. Instead of absconding with their prize, the viruses force the bacteria to burn their valuable sulfur...

Genetic Mix Of Bacterial Diversity Found In One Milliliter Of Sea Water
2014-04-25 11:33:10

Brett Smith for redOrbit.com - Your Universe Online Countless marine microbes called Prochlorococcus are the primary basis for most ocean food webs, yet microbiologists know very little about the diversity with this group of photosynthetic bacteria. A new study, published in the journal Science, describes hundreds of subpopulations of these essential marine bacteria. An international team of researchers were able to identify the different subgroups through a comprehensive genomic...

Symbiosis Between Beewolves And Their Protective Bacteria Originated Millions Of Years Ago
2014-04-16 14:43:12

Max Planck Institute for Chemical Ecology Like humans, many animals depend on beneficial microbes for survival. Although such symbioses can persist for millions of years, the factors maintaining their long-term stability remain, in most cases, unknown. Scientists from the Max Planck Institute for Chemical Ecology and the University of Regensburg, in collaboration with researchers in the USA, now discovered that certain wasps tightly control mother-to-offspring transmission of their...

Study May Resolve Controversy Over Nitrogen’s Ocean Exit Strategies
2014-04-14 12:19:53

By Catherine Zandonella, Princeton University A decades-long debate over how nitrogen is removed from the ocean may now be settled by new findings from researchers at Princeton University and their collaborators at the University of Washington. The debate centers on how nitrogen — one of the most important food sources for ocean life and a controller of atmospheric carbon dioxide — becomes converted to a form that can exit the ocean and return to the atmosphere where it is reused...

Wistar Findings Suggest Link between Colon Microbiome and Genome Stability Colorectal cancer develops in what is probably the most complex environment in the human body, a place where human cells cohabitate with a colony of approximately 10 trillion bacteria, most of which are unknown. At the 2014 American Association for Cancer Research Annual Meeting in San Diego, researchers from The Wistar Institute will present findings that suggest the colon “microbiome” of gut bacteria can...

Bacterial Biofilms Used To Create Lifelike Materials
2014-03-24 04:29:52

redOrbit Staff & Wire Reports - Your Universe Online By drawing inspiration from the way in which minerals, living cells and other substances combine to form bone, a team of MIT engineers have created a type of “living material” out of bacterial cells, according to research appearing in Sunday’s edition of the journal Nature Materials. Lead author Allen Chen, an MIT-Harvard MD-PhD student, and his colleagues coaxed those cells to produce biofilms capable of incorporating...
