Engineering the Microbiome: CRISPR Leads the Way
Mariella Bodemeier Loayza Careaga, PhD | Mar 15, 2024 | 10+ min read
Scientists have genetically modified isolated microbes for decades. Now, using CRISPR, they intend to target entire microbiomes.

The Inside Guide: The Gut Microbiome’s Role in Host Evolution
Catherine Offord | Jul 1, 2021 | 10+ min read
Bacteria that live in the digestive tracts of animals may influence the adaptive trajectories of their hosts.
When Stop Means Go
Ruth Williams | May 22, 2014 | 3 min read
A survey of trillions of base pairs of microbial DNA reveals a considerable degree of stop codon reassignment.
An Ocean of Viruses
Joshua S. Weitz and Steven W. Wilhelm | Jul 1, 2013 | 10+ min read
Viruses abound in the world’s oceans, yet researchers are only beginning to understand how they affect life and chemistry from the water’s surface to the sea floor.
First DOE Microbe Sequencing Project Grants Widely Hailed As Potential `Treasure Trove'
Karen Young Kreeger | Feb 5, 1995 | 6 min read
A recently established Department of Energy (DOE) initiative is expected to yield major scientific and commercial contributions as it embarks on its multimillion-dollar effort to sequence the entire genome of several free-living microorganisms. Scientists anticipate that the program will substantially expand understanding of evolutionary relationships, while it also advances genome-sequencing technology. Commercial application of the sequences, such as industrial enzymes used in cleaning up th
How Interconnected Is Life in the Ocean?

To help create better conservation and management plans, researchers are measuring how marine organisms move between habitats and populations.
Bt or not Bt ... Transgenic Corn vs. Monarch Butterflies
Barry Palevitz | Jun 6, 1999 | 5 min read
John Losey thought his Nature paper might attract some attention, but not the media "whirlwind" of "a good 60 calls" that disrupted his life for a few days. Losey, assistant professor of entomology at Cornell University, "expected to be busy, but not quite this busy." What prompted the fuss? By claiming that a gene for a Bacillus thuringiensis (Bt) toxic protein makes corn pollen poisonous to Monarch butterflies,1 Losey's team ignited another round in the volatile politics of genetically modifi
Putting It Together

BIOREMEDIATION TO THE PIGPEN It was a stinky summer at the EnviroPork hog facility near Larimore, N.D., with penalties pending for violating state odor regulations, and neighbors complaining loudly about the foul fragrance. Making matters worse, the manure lagoon associated with the facility threatened groundwater supplies. Happily, researchers from the University of North Dakota Energy and Environmental Research Center (EERC) had a low-tech solution: barley straw. Using a cannon, they shot a
Hot-Vent Microbes: Looking Backward In Evolution For Future Uses
Myrna Watanabe | May 29, 1994 | 7 min read
They live--thrive, even--in boiling water! They feed on sulfur or hydrogen. They could be from one of the moons of Jupiter. In fact, their existence here on Earth has led scientists to realize that planets they hitherto assumed to be lifeless might support life. These thermophilic, or heat- loving, microbes--Archaea--are attracting a small but growing cadre of researchers and serious research funding from the United States governmen
