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.
Bacteria Harbor Geometric “Organelles”
Amber Dance | Dec 1, 2018 | 10+ min read
Microbes, traditionally thought to lack organelles, get a metabolic boost from geometric compartments that act as cauldrons for chemical reactions. Bioengineers are eager to harness the compartments for their own purposes.

Getting to Megabase
Jorge Cortese | Dec 5, 1999 | 7 min read
Large Fragment Cloning Products and Services Gone are the days when all you had to do to get out of grad school was identify and clone a new gene. Besides, with the information rapidly gathered through the Human Genome Project, there will soon no longer be a "new gene." Enormous projects such as sequencing entire genomes have created a need to play with bigger pieces of the puzzle, and a new universe of technologies adapted to large DNA fragments has appeared. Assignment of a new gene to a par

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
