Findings point to digestive bacterial influence on choline metabolism The more we learn about biology, the closer we get to being able to treat disease "“ and the more complicated our understanding of disease itself becomes. A new research finding showing a strong relationship between complex microbial ecologies in human intestines and the common but serious medical condition known as fatty liver illustrates this paradox. From past genomic studies, we have learned that a mind-boggling...

When it comes to breaking down plant matter and converting it to energy, the cow has it all figured out. Its digestive system allows it to eat more than 150 pounds of plant matter every day. Now researchers report that they have found dozens of previously unknown microbial enzymes in the bovine rumen "“ the cow's primary grass-digestion chamber "“ that contribute to the breakdown of switchgrass, a renewable biofuel energy source. The study, in the journal Science, tackles a major...

A specific kind of ancient rock art found in Western Australia has managed to maintain its vivid colorization and high contrast over more than 45,000 years because it is comprised of living organisms, researchers from the University of Queensland have discovered. The Bradshaw rock art, which was named after the 19th century naturalist who first discovered them, has been exposed to sunlight and rain for up to 70,000 years and has never been repainted. Now researchers Jack Pettigrew, Chloe...

A mounting tide of scientific evidence suggests that the old adage from Aesop's fables "” "You are known by the company you keep" "” also applies to the trillions of microscopic bacteria and viruses that live on the human body. Humanity's invisible but constant companions "” more bacteria hang out on the palms of your hands than there are people on Earth "” is the topic of an article in the current edition of Chemical & Engineering News (C&EN), ACS' weekly...

The human body is home to a complex ecosystem of microbes increasingly recognized as having a critical role in both health and disease. Viruses can attack and change the composition of bacterial communities, yet little is known about how this might influence human health. In a study published online today in Genome Research (www.genome.org), scientists have performed the first metagenomic analysis of a bacterial immune system in humans over time, finding that the defenses of the oral...

Research gives clearer picture of inhabitants living in ocean surface and gleans insights into how they adapt and survive ROCKVILLE, Md. and SAN DIEGO, Nov. 3, 2010 /PRNewswire-USNewswire/ -- Researchers at the J. Craig Venter Institute (JCVI), a not-for-profit genomic research organization, published results today describing the sequencing and analysis of 137 marine microbial genomes living in the global ocean surface. The research was published by JCVI lead authors Shibu Yooseph and...

A University of Oklahoma technology"”GeoChip"”played a critical role in an intensive study of the dispersed oil plume that formed at a depth between 3,600 and 4,000 feet some 10 miles from BP's Deepwater Horizon drilling rig in the Gulf of Mexico. An OU research team led by Jizhong Zhou, director of the Institute for Environmental Genomics, developed the new generation GeoChip, which contributed to the findings of the study by simultaneously detecting more than 150,000 different...

Home to a diverse range of microorganisms, a healthy human body contains at least tenfold more bacteria cells than human cells. The most abundant and diverse microbial community resides in the intestine, and changes to the gut microbiota are linked with diseases such as ulcerative colitis and Crohn's disease. In a report published online today in Genome Research (www.genome.org), researchers have analyzed the long-term effects of gut bacterial transplantation in rats, revealing crucial...

At birth, your body was 100-percent human in terms of cells. At death, about 10-percent of the cells in your body will be human and the remaining 90-percent will be microorganisms. That makes you a "supraorganism," and it is the interactions between your human and microbial cells that go a long way towards determining your health and physical well-being, especially your resistance to infectious diseases. To learn more about the community of symbiotic microbes that outnumber our own somatic...

More than a thousand microbial genomes have been sequenced at various sequencing centers in the past 15 years to better understand their roles in tasks ranging from bioenergy to health to environmental cleanup. Conservative estimates suggest roughly 10,000 microbial genomes will be publicly available within the next two years, but genomic standards have not caught up with the technological advances that have made the sequencing process faster and cheaper. As a result, the torrent of DNA...
