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.

Similar Data, Different Conclusions
Ashley P. Taylor | Feb 23, 2016 | 6 min read
By tweaking certain conditions of a long-running experiment on E. coli, scientists found that some bacteria could be prompted to express a mutant phenotype sooner, without the “generation of new genetic information.” The resulting debate—whether the data support evolutionary theory—is more about semantics than science.

Illuminating Behaviors
Douglas Steinberg | Jun 1, 2003 | 6 min read
Courtesy of Genevieve Anderson If not for Nobel laureates Thomas Hunt Morgan, Eric R. Kandel, and Sydney Brenner, the notion of a general behavioral model might seem odd. Behaviors, after all, are determined by an animal's evolutionary history and ecological niche. They are often idiosyncratic, shared in detail only by closely related species. But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t
Chloroplast Studies Point to Crop Enhancements
Barry Palevitz | Apr 11, 1999 | 5 min read
With news about Dolly and embryonic stem cells the stuff of cocktail party conversation, cloning a transgenic sheep or cow seems like child's play. The recipe is simple: Insert a pet gene into the nucleus of a cultured cell, fuse it with an enucleated egg, and voilà--a cow with high-octane milk. But incorporating genes into nuclear chromosomes isn't the only road to fame and fortune. Animals and plants have other sources of genetic information--their respiratory mitochondria and photosy

Some Cancers Become Contagious
Katarina Zimmer | Apr 1, 2019 | 10+ min read
So far, six animal species are known to carry transmissible, “parasitic” forms of cancer, but researchers are still mystified as to how cancer can become infectious.
