Aptamers Identify Protein Signatures
Ricki Lewis | Apr 1, 2001 | 3 min read
Graphic: Leza BerardoneA technique not deemed "sexy" enough for commercialization a decade ago may finally find its niche in proteomics. SomaLogic Inc. of Boulder, Colo. is pioneering aptamers, which are modified DNA molecules that bind specific proteins in body fluid samples. Aptamers are initially selected for specific binding activities from a huge starting pool, then variants are obtained during subsequent rounds of amplification. The technology builds on the ability of aptamers to bind tena
Drug Makers on the Apoptotic Trail

Apoptosis, a key process in the development of embryonic tissue differentiation, later helps to regulate the normal cellular life cycle by destroying damaged cells. When something goes awry, too little apoptosis can make cancer cells resistant to chemotherapy and even death-defiant. At the other extreme, premature or excessive apoptosis has been linked to neurodegenerative diseases, such as Alzheimer's, and to nerve cell loss in strokes. Not surprisingly, many major pharmaceutical companies rec
The Biggest Stories in Bioscience 2005

Life scientists have been challenged more than ever this year not just to critically analyze data, but to better interpret those data for an increasingly critical public.

On June 14, a House Appropriations subcommittee gave some researchers cause for celebration when it surprisingly voted to remove a provision in a government spending bill that extended a ban on federal funding of human embryo research. However, their glee was short-lived. The full panel turned around on June 25 and adopted an amendment to continue the research ban. John Eppig, senior staff scientist at Jackson Laboratory in Bar Harbor, Maine, doubts that the ban will be overturned anytime soon,
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
In A Darwinian World, What Chance For Design?
Steve Bunk | Apr 12, 1998 | 7 min read
Swiss anthropologist Jeremy Narby counts himself among the relatively thin ranks of scientists willing to publicly announce their conviction that nature is "minded," that an intelligence lies behind the development of life. Such a position is heresy to the prevailing scientific view of naturalism, which holds that nature is self-sufficient and the result of undirected processes. These two differing viewpoints usually are framed in the context of a debate between theology and science--creationis
