Migration: Micro and Macro
Ruth Padel | Jun 1, 2012 | 3 min read
Biology and history both tell us that life began with migration: from cells to sharks, hummingbirds to human beings, life migrates for three reasons—survival, protection, and reproduction.

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

How to Create a Successful Fish Tale?
A. J. S. Rayl | Aug 19, 2001 | 10+ min read
More than 80 percent of the planet's living organisms exist only in aquatic ecosystems. Some may harbor secrets to human origins, and clues, treatments--perhaps even cures--for human disease. Some are critical bioindicators that portend the health of the biosphere. Yet, overall, scientists know little about the biochemical processes of these life forms. The vast, rich knowledge within the oceans and freshwater systems on Earth remains virtually untapped, because in the world of biological resear
Ribozymes: Hearkening Back to an RNA World
Jeffrey Perkel | Sep 15, 2002 | 9 min read
Illustration: Ned Shaw LIKE MOLECULAR TOY-MAKERS, ribozyme researchers create tools with evolutionary, diagnostic, and therapeutic applications. Nearly 20 years ago, Tom Cech and Sidney Altman discovered that some naturally occurring RNAs could perform enzymatic reactions, earning these researchers the 1989 Nobel Prize in chemistry. Scientists have now identified several examples of RNA enzymes, or ribozymes. Most make or break the phosphodiester bonds in nucleic acid backbones, but some
Deviations From The Norm: Systems For Mutation Detection Reveal Hidden Potentials

Date: July 19, 1999Mutation Detection Systems and Methods Affymetrix's p53 chip Researchers leading the Human Genome Project (HGP) originally envisioned completion of the entire genome sequence (approximately 3 billion base pairs) by the year 2005. Recently the arena of human genome sequencing has seen a lot of heat generated by the entry of both commercial entrepreneurs and public consortia. Celera, a company formed by highly skilled and competent commercial organizations (TIGR and Perkin-Elm
