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.

DEINO-MITE CLEANUP In 1956, investigators discovered a potentially invaluable cleanup tool in an unlikely place. A hardy bacterium called Deinococcus radiodurans unexpectedly thrived in samples of canned meat thought to be sterilized by gamma radiation. The b
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

With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c

Pursuing Proteomes
Deborah Wilkinson | Jun 11, 2000 | 9 min read
Bio-Rad's PROTEAN® IEF System provides 2-D electrophoretic separation as part of the ProteomeWorks System Australian postdoctoral fellow Marc Wilkins coined the term "proteome" in the mid-'90s, referring to the total set of proteins expressed in a given cell at a given time. The term took hold, and a new scientific discipline was born. In proteomic studies, all the proteins from a given cell, organelle, or tissue are analyzed simultaneously with respect to properties such as expression leve
Olfaction Scientists: Sniffing Out Some New Applications
Robin Eisner | Nov 11, 1990 | 9 min read
A wide range of scientific challenges spawns a surge in basic research for this once unacclaimed discipline Most researchers long believed that the sense of smell was genetically determined and, therefore, unchangeable. But at least one scientist--Charles Wysocki of the Monell Chemical Senses Center in Philadelphia--doubted this theory. Wysocki, a psychobiologist who investigates the genetics of olfaction in the 45 percent of the adult population who can't detect androstenone, a component in s

Date: September 13, 1999Table of Neurochemical Manufacturers The hypothalamus has long been known as a control center for feeding and weight control behaviors. Complex regulatory feedback loops enable this portion of the brain to determine satiety and metabolic activity. Not surprisingly, the control mechanisms are complex and involve different biochemical pathways.1,2,3 Image courtesy of Jeffrey M.
