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...

The interactions of the gut microbiota in children with typical diabetes autoantibodies differ from that in healthy children. The fact that these differences already exist before antibodies are detectable in the blood adds to the growing evidence that microbial DNA, the so-called microbiome, may be involved in the development of autoimmune processes. Scientists from the Helmholtz Zentrum München have published their findings in the specialist journal Diabetes. As part of the BABYDIET...

Garlic Substance Can Help Give Antibiotics A Boost When Fighting Resistant Bacteria
2014-02-19 03:57:45

redOrbit Staff & Wire Reports - Your Universe Online A substance found in garlic can help combat even the most aggressive and treatment-resistant strains of bacteria, a doctoral candidate from the University of Copenhagen has discovered as part of a PhD thesis on the beneficial properties of the odoriferous plant and commonly-used culinary ingredient. The discovery, which was made by Faculty of Health and Medical Sciences student Tim Holm Jakobsen, comes as aggressive...

New Insights Into How Biofilms Form Provided By CMOS Technology
2014-02-11 11:52:58

[ Watch the Video: Chips that Listen to Bacteria ] Holly Evarts - Columbia University School of Engineering and Applied Science In a study published today in Nature Communications, a research team led by Ken Shepard, professor of electrical engineering and biomedical engineering at Columbia Engineering, and Lars Dietrich, assistant professor of biological sciences at Columbia University, has demonstrated that integrated circuit technology, the basis of modern computers and...

Photosynthesis-Activating Protein Likely Predates Oxygen On Earth
2014-02-09 08:21:12

[ Watch the Video: Photosynthesis Older Than Oxygen ] redOrbit Staff & Wire Reports – Your Universe Online Thioredoxin, a protein essential to the process of photosynthesis in plants, likely developed on Earth long before oxygen ever became available, according to a study published in last week’s early online edition of the Proceedings of the National Academy of Sciences. In the study, an international team of researchers analyzing methane-producing microbes found that...
