What’s the Deal with Bacterial Nanotubes?
Sruthi S. Balakrishnan | Jun 1, 2021 | 10+ min read
Several labs have reported the formation of bacterial nanotubes under different, often contrasting conditions. What are these structures and why are they so hard to reproduce?
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.

Microbial Multicellularity

Eye of Science / Photo Researchers, Inc. "The general character and structure of the rod-like individuals, together with their vegetative multiplication by fission, renders their schizomycetous nature as individuals a matter hardly to be doubted: but, on the other hand, the question may fairly be asked whether the remarkable phenomena may not indicate a possible relationship in other directions." --Roland Thaxter, 1892 While walking through the New England woods one day in the late 19th c
Bringing Living Cells Into Focus: A View of Inverted Microscopes
Jim Kling | Mar 29, 1998 | 5 min read
Date: March 30, 1998 Author: Jim Kling Tables of Vendors What's really going on here? That question used to puzzle bleary-eyed microscopists as they stared at slides of immobilized cells--dead cells, of course. Then along came the inverted microscope. Its unique design placed the light source above the sample and the magnifying objective below it, allowing these new microscopes to peer into live cells bathed in media. Suddenly, scientists had a new view of the neighborhoods and boroughs occupied

Courtesy of SR Eng  BABY STAINS: The head of a transgenic murine embryo in which a marker enzyme has been specifically expressed in the sensory neurons of the trigeminal and dorsal root ganglia. The marker allows staining of the projections of these neurons into, among other areas, the hindbrain and spinal cord. (S.R.

NAS Honors 15 For Contributions To Science
Eugene Russo | Apr 26, 1998 | 7 min read
Seven life scientists are among the 15 honorees for this year's National Academy of Sciences award ceremony set for today at the NAS's 135th annual meeting in Washington, D.C. The meeting also includes the induction of academy members elected last year (E.R. Silverman, The Scientist, 11[9]:1, April 28, 1997). The academy is presenting its highest honor, the Public Welfare Medal, to David A. Hamburg, president emeritus of the Carnegie Corp. of New York. Hamburg, 72, is being recognized "for his
