A Look at Drosophila Pattern Formation
Jeffrey Perkel | Sep 2, 2001 | 9 min read
Researchers interested in gene expression studies adopt one of two approaches. They can either examine the expression of a given gene in a population of cells in aggregate, or they can study the gene on a cell-by-cell basis in situ. The advantage of the former approach is its simplicity: It is generally easy to prepare RNA or protein from a given tissue sample and to probe it for the gene or protein of interest. But there are several disadvantages associated with the population approach. First o
Who Sleeps?
The Scientist and Jerome Siegel | Mar 1, 2016 | 10+ min read
Once believed to be unique to birds and mammals, sleep is found across the metazoan kingdom. Some animals, it seems, can’t live without it, though no one knows exactly why.
All's Well that Ends Well: A Profile of Specialty Microwell Plates

Date: September 27, 1999Table of Specialty Microplates The story of the microplate is one of those tales of history that either has been forgotten or was never clearly understood. According to Barry Lazar of Dynex Technologies, formerly Dynatech Laboratories, the origin of what is now commonly referred to by Dynex's registered trademark of Microtiter plates began with Gyola Takatsy, a Hungarian-born scientist who was trying to scale down serology tests. His first prototype became available in 1

Flies Invade Human Genetics
Ricki Lewis | Jun 21, 1998 | 9 min read
  DOUBLE WINGS: An ultrabithorax mutant fly has a total duplication of the body segment that carries wings. Recent issues of The American Journal of Human Genetics have featured a newcomer: Drosophila melanogaster. The fruit fly is a frequent star of a series of review articles called "Insights From Model Systems." The insect's appearance in a human genetics journal is a telling sign that this model among model organisms, long used to decipher the general principles of inheritance

F1000 Recommendation: Must Read "This is a good paper showing the large scale analysis of a very large protein complex, the nucleolus. [Points of interest]: The size of the complex and that it is dynamic. The mass spectrometry methods used here were a combination of high throughput (matrix-assisted laser desorption ionization coupled to time of flight detection) and low throughpu
60 Members Elected to NAS

Editor's Note: On May 2, the National Academy of Sciences announced the election of 60 new members and 15 foreign associates from nine countries in recognition of their distinguished and continuing achievements in original research. Nearly half of the new members are life scientists. In this article, The Scientist presents photographs of some of the new members and comments from a few of them on their careers and on past and current research. A full directory of NAS members can be found online a

Courtesy of BD Biosciences Pharmingen  COLOR CODING: Multiplexed bead-based assays, like BD Biosciences' Cytometric Bead Array (shown), test for multiple analytes in a single vial. The key is in the colors: one hue indicates the bead ID, and the intensity of the second, how much protein has been captured. In today's fast-paced research environment, technologies for speedy, cost-efficient analyses reign supreme. As part of this general trend, techniques for multiplexing, that is, simultan
