The study of ancient microbes may not seem consequential, but such pioneering research at the University of Oklahoma has implications for the state of modern human health. Cecil Lewis, assistant professor in the Department of Anthropology, says results of this research raise questions about the microbes living on and within people. A National Institutes of Health initiative is looking at helpful bacteria found on the skin, in the esophagus and in the stomach, by characterizing the microbe's...

An international team led by a U.S. researcher has completed genome sequencing for an extinct animal, offering insight into its modern-day cousin. Using DNA extracted from samples of the pre-historic woolly mammoth's hair, Pennsylvania State University biology Stephan Schuster and his 20 teammates collected the near-complete nuclear genome, the team reported in the journal Nature Wednesday. Samples from several different mammoth species preserved in permafrost were used in the sequencing...

Using the Genome Sequencer System from 454 Life Sciences, a Roche company, French scientists have identified a small virus that can actually be parasitic to a larger one. The 50 nm virus, named Sputnik, is associated with a new strain of the giant Acanthamoeba polyphaga mimivirus (APMV) and is believed to represent a currently unknown family of viruses. The study, entitled "The virophage as a unique parasite of the giant mimivirus," appeared in the September 4th issue of Nature (1). The...

By Drenovsky, Rebecca E Feris, Kevin P; Batten, Katharine M; Hristova, Krassimira ABSTRACT.- Interest in the relationships between soil microbial communities and ecosystem functions is growing with increasing recognition of the key roles microorganisms play in a variety of ecosystems. With a wealth of microbial methods now available, selecting the most appropriate method can be daunting, especially to those new to the field of microbial ecology. In this review, we highlight those methods...

U.S. scientists say they've created a method that can extract single genomes and discern specific microbial capabilities from sequence data. Researchers from the University of Washington and the U.S. Department of Energy's Joint Genome Institute say they have developed a novel approach for extracting single genomes and then discerning specific microbial capabilities from metagenomic sequence data. Metagenomics is the study of genetic material recovered directly from environmental samples....

ROCKVILLE, Md. and LA JOLLA, Calif., June 26 /PRNewswire-USNewswire/ -- The J. Craig Venter Institute (JCVI), a not-for-profit genomic research organization, today announced that Robert Friedman, Ph.D., has been named the new Deputy Director of the JCVI La Jolla, California facility. The organization also announced the promotion of several key science leaders -- Karen Nelson, Ph.D., Samuel Levy, Ph.D., and Yu-Hui Rogers, in the Rockville, Maryland headquarters. In his new role, Dr....

Viruses and bacterial viruses (known as phages) are among the most abundant life forms on the planet. Two papers published recently in Nature, March 2 and 12, 2008, analyze the geographical distribution of viral communities in modern organosedimentary structures (sedimentary features, built by the interaction of organisms and their environment) known as microbialites, the living analogues of the oldest fossils on Earth, and come up with some surprising nuggets of information.Microbialites...

Microbial profiles serve as the ecological version of the human genome projectNowhere is the principle of "strength in numbers" more apparent than in the collective power of microbes: despite their simplicity, these one-cell organisms - which number about 5 million trillion trillion strong (no, that is not a typo) on Earth - affect virtually every ecological process, from the decay of organic material to the production of oxygen.But even though microbes essentially rule the Earth, scientists...

Intriguing find reveals more mysteries from Mexico's Cuatro Cienegas Biologists examining ecosystems similar to those that existed on Earth more than 3 billion years ago have made a surprising discovery: Viruses that infect bacteria are sometimes parochial and unrelated to their counterparts in other regions of the globe. The finding, published online this week by the journal Nature, is surprising because bacteria are ubiquitous on Earth. They've been found from the upper reaches of the...

Microbes living in the oceans play a critical role in regulating Earth's environment, but very little is known about their activities and how they work together to help control natural cycles of water, carbon and energy. A team of MIT researchers led by Professors Edward DeLong and Penny Chisholm is trying to change that. Borrowing gene sequencing tools developed for sequencing the human genome, the researchers have devised a new method to analyze gene expression in complex microbial...
