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.
Engineered Microbe in Bees’ Guts Fends off Deadly Varroa Mite

The genetically modified bacteria spark an RNAi response in the parasite that leads to self-destruction—and perhaps a path to combatting colony collapse disorder.

Whole-Genome SNP Genotyping
Marilee Ogren | Jun 1, 2003 | 8 min read
Clockwise from top left: images courtesy of Affymetrix, Illumina, Sequenom and Illumina Take any two individuals, sequence and compare their genomic DNA, and you'll find that the vast majority (about 99.9%) of the sequences are identical. In the remaining 0.1% lie differences in disease susceptibility, environmental response, and drug metabolism. Researchers are understandably keen to dissect these variations, most of which take the form of single-nucleotide polymorphisms (SNPs). A SNP (pron

PCR Primed To Spur Chain Of Applications
Holly Ahern | Jun 25, 1995 | 10+ min read
What would you do if your research interests revolved around obtaining DNA from a bacterium preserved for millions of years in the gut of a bee stuck in amber, matching up a murderer to crime- scene blood half a century old, or cloning genes from a 1,000- year-old mummy? Most scientists would first consider PCR--the polymerase chain reaction--as a technique for approaching problems such as these. With PCR, minute quantities of nucleic acids can be amplified millions of times into sufficient qua
The Infection Connection in Schizophrenia
Brendan Maher | Nov 2, 2003 | 7 min read
Adapted from image by I.I. Gottesman ©2001  GENES AND MORE: The risks of developing schizophrenia over a lifetime to the relatives of schizophrenia sufferers accord with a largely genetic explanation. Yet with 48% concordance for identical twins, environmental factors may play a role. It's a scary thought that one could develop a debilitating mental illness such as schizophrenia as easily as catching a cold. Well, it's more complicated than that, say advocates of the so-called infec
