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.

A GRADIENT OF PORE SIZES:Courtesy of Michael J. Sailorimparts a rainbow of colors to a porous silicon chip, one of a variety of new biosensor technologies in development around the world. The different colors correspond to different sized pores, ranging from a few nanometers to hundreds of nanometers in diameter. These pores help the device discriminate and detect proteins and other molecules based on their size.One morning in March 1995, the deadly nerve gas sarin wafted through the Tokyo subwa
Human Clinical Trials Begin For Cervical Cancer Vaccines
Steve Bunk | Oct 26, 1997 | 6 min read
Efforts are under way to develop a vaccine against one of the world's deadliest illnesses, cervical cancer. Along with a number of university research laboratories, at least a half-dozen biotechnology and pharmaceutical companies are beginning clinical trials or are in preclinical development of such drugs. Efficacy in humans remains to be firmly established, but if the vaccines progress to later-phase trials, challenging jobs for immunologists, microbiologists, and biochemists will multiply. "
One Step Beyond: Going Beyond Genomics With Proteomics And Two-Dimensional Gel Technology
Laura Defrancesco | Jan 3, 1999 | 10+ min read
Proteomes and 2D Gel Apparatus Providers Big science has moved on to proteins. With the new brand of science termed proteomics--named by the Australians Marc Wilkins and Keith Williams to mean the "set of PROTEins encoded by the genOME"--the push is on around the globe to produce a complete description of a cell/tissue/organism in terms of the proteins produced. The challenge is all the greater because the expressed protein pattern changes with time and environment--responding to developmenta
