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?
Beyond Film: Laboratory Imagers
Jorge Cortese | Apr 1, 2002 | 9 min read
Years ago, researchers had only one data-imaging option: autoradiography. These scientists tagged samples—whether nucleic acid, protein, cell, or tissue—with radioactive labels, and captured images on film. Safety concerns, convenience, and sensitivity, spurred the development of alternative techniques, and today, researchers can choose from a range of options, including fluorescence, chemifluorescence, and chemiluminescence, in addition to autoradiography. Fluorescence occurs when
Sorting out the Science of Stickiness
Ricki Lewis | Feb 3, 2002 | 6 min read
For many animals, to stick is to survive. Nature's varied adhesive structures and substances enable animals to stick to inert substrates, to each other, and even to parts of themselves. An octopus uses its suckers to grab food, a gecko coordinates its highly specialized feet to ascend a wall, and a mussel emits strings of proteinaceous goo to hold fast to a rock in times of turbulence. Insects coordinate their jumping motions by choreographing contact of leg parts. Some species can even multitas

if (n == null) The Scientist - The Immune Response The Scientist 9[18]:18, Sep. 18, 1995 Tools The Immune Response By Holly Ahern Imagine that you've just cloned a gene for a bacterial enzyme with unique structural properties and you want to find out more about it. What natural role does the enzyme play, you wonder, and do organisms other than bacteria produce it? To answer these questions, you could screen countless genomic libraries for clones bearing si
