The Gates of Immortality
Yves Barral | Oct 1, 2010 | 10+ min read
By Yves Barral The Gates of Immortality Did biology evolve a way to protect offspring from the ravages of aging by creating a physical barrier that separates the parent from its young? Dr. Stanley Flegler, Visuals Unlimited he idea that every organism must age was a concept that surprised many biologists. For a long time, aging was thought to be a process occurring only in multicellular organisms. The reason for this arguably odd presumption was that we knew so

Biotech's new invaluable tool
Jef Akst | Sep 15, 2010 | 4 min read
In just two decades, the protein equivalent of an intron has carved out a significant niche in biotechnology -- and captured the interest of evolutionary biologists, who suspect these potentially ancient elements could provide clues to early enzymes. Image: Wikimedia commonsWith the ability to splice themselves out of proteins and paste the two loose ends of the protein back together, inteins are proving to be an invaluable tool in biotechnology. Just 20 years since their discovery, inteins are

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
