Microbial organisms associated with plant roots have far-flung global influences, from plant genetics to ecosystem health We often ignore what we cannot see, and yet organisms below the soil's surface play a vital role in plant functions and ecosystem well-being. These microbes can influence a plant's genetic structure, its health, and its interactions with other plants. A new series of articles in a Special Section in the American Journal of Botany on Rhizosphere Interactions: The Root...

Your Gut’s Microbiome Has A Unique Bacteria Profile
2013-04-24 07:27:18

April Flowers for redOrbit.com - Your Universe Online In the human body, microbial cells outnumber human cells ten to one. Your body has a set of microbial communities collectively known as a microbiome. Scientists studying the microbiome are learning about the relationship between these microbes and human health and disease. Dr. Nanette Steinle of the University of Maryland's School of Medicine and Dr. Emmanuel Mongodin of the University of Maryland Institute of Genome...

BETHESDA, Md., March 14, 2013 /PRNewswire-USNewswire/ -- In a healthy adult, microbial cells are estimated to outnumber human cells 10 to one. Many microbes maintain our health, while others cause illness. Recent investigations of the human gut microbiome have discovered important ways in which gut microbes may influence a number of important disease states including obesity, inflammatory bowel disease, functional gastrointestinal disorders, cancers and liver disease. Recognizing the major...

Algae Held Captive And Their Genes Stolen In Crime Of Evolution
2012-11-28 15:38:41

University of Melbourne Microscopic animals held algae captive and stole their genes for energy production, thereby evolving into a new and more powerful species many millions of years ago reveals a new study published today in the journal Nature. The results reveal a 'missing link' in evolution because the tiny animal thieves (protozoa) couldn't completely hide all evidence of the captive algae, and have been effectively frozen in time and caught in the act by genetic sequencing....

Coral Reef Diversity - Sometimes Less Is More
2012-08-29 10:08:25

Brett Smith for redOrbit.com - Your Universe Online A general rule of Darwinian evolution is that diversity provides for a more robust population that is capable of withstanding a higher degree of stress than a more homogenous population. However, researchers at the University of Hawaii at Manoa (UHM) have found that less diverse coral populations lead to reefs that are less sensitive to environmental disturbances, according to their report in Proceedings of the Royal Society B....

New Open Access Publication to Highlight Microbiome Research in Humans and the Environment BALTIMORE, July 11, 2012 /PRNewswire-USNewswire/ -- Two prominent microbial genome scientists have launched a new peer-reviewed publication focusing on microbiome research in environmental, agricultural, and biomedical areas. Jacques Ravel, Ph.D., from the University of Maryland School of Medicine's Institute for Genome Sciences and Eric Wommack, Ph.D., from the University of Delaware are the...

A study of the microbiome of the human nose provides clues to the cause of a chronic sinus condition and potential strategy for a cure. Researchers from the University of California, San Francisco report their findings today at the 2012 General Meeting of the American Society for Microbiology. Chronic rhinosinusitis (CRS) is characterized by inflammation of the nasal and paranasal sinuses lasting over 12 weeks. Patients suffering from this disease experience a variety of symptoms including...

Map Of Bacterial Makeup Of Humans Reveals Microbial Rare Biosphere
2012-06-13 19:43:22

NIH Human Microbiome Project finds patterns of microbial diversity, distributions earlier discovered in ocean ecosystems by scientists at MBL Woods Hole The landmark publication this week of a "map" of the bacterial make-up of healthy humans has deep roots in an unexpected place: the ocean. Microbial communities that live on and in the human body, known collectively as the microbiome, are thought to have a critical role in human health and disease. Five years ago, the National...

Microorganisms in the human gastrointestinal tract form an intricate, living fabric made up of some 500 to 1000 distinct bacterial species, (in addition to other microbes). Recently, researchers have begun to untangle the subtle role these diverse life forms play in maintaining health and regulating weight. In a new study appearing in the journal Nutrition in Clinical Practice, researcher Rosa Krajmalnik-Brown and her colleagues at the Swette Center for Environmental Biotechnology at...

Humans spend greater than 90 percent of their time indoors, but we're never alone there. Bacteria and viruses, scientists estimate, make up half of the world's biomass–some 10 nonillion (1 followed by 31 zeros) microorganisms–and we most often meet them within enclosed spaces. So, that's where the modern microbe hunter often looks first. A new report issued by the National Institute of Standards and Technology (NIST) offers guidance to make the hunting more effective. A...
