Unearthing the Evolutionary Origins of Insect Wings
Jef Akst | Apr 4, 2022 | 6 min read
A handful of new studies moves the needle toward a consensus on the long-disputed question of whether insect wings evolved from legs or from the body wall, but the devil is in the details.

Genome Investigator Craig Venter Reflects On Turbulent Past And Future Ambitions
Karen Young Kreeger | Jul 23, 1995 | 8 min read
And Future Ambitions Editor's Note: For the past four years, former National Institutes of Health researcher J. Craig Venter has been a major figure in the turbulent debates and scientific discoveries surrounding the study of genes and genomes. Events heated up in 1991, when NIH attempted to patent gene fragments, which were isolated using Venter's expressed sequence tag (EST)/complementary DNA (cDNA) approach for discovering human genes (M.A. Adams et al., Science, 252:1651-6, 1991). NIH's mo

With human research trials resulting in dozens of successful deliveries in the US and abroad, doctors move toward offering the surgery clinically, while working to learn all they can about uterine and transplant biology from the still-rare procedure.
Surpassing the Law of Averages
Jeffrey M. Perkel | Sep 1, 2009 | 7 min read
By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.
Gene Mapping Gives Rise To Drugs That Rebuild Tissue
Steve Bunk | Apr 26, 1998 | 8 min read
The logical outcome of gene mapping is nigh. Biotechnology companies are using genetic information to design new drugs that may go beyond merely slowing or stopping a disease process to inducing the regeneration or repair of damaged tissue. Looking past the conventional drug targets of enzymes and gene-coupled receptors, researchers are seeking out molecules in the pathways along which biochemical signals are transferred. In some cases, their work has led to compounds--now in clinical trials or
