Sensory Biology Around the Animal Kingdom
The Scientist | Sep 1, 2016 | 10+ min read
From detecting gravity and the Earth’s magnetic field to feeling heat and the movement of water around them, animals can do more than just see, smell, touch, taste, and hear.

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?
Interface Between Biology And Mathematics Expanding Rapidly
Neeraja Sankaran | Jul 9, 1995 | 7 min read
Biologists and mathematicians alike are finding their respective disciplines meeting at a very busy crossroads. The rapid advances in both fields, they say, have resulted in an explosion of information in the life sciences, and the creation of sophisticated mathematical tools for handling complicated biological systems. Studies over the entire range of the life sciences--from the molecular level (DNA and proteins) to entire organisms and ecosystems--benefit from insights derived from the mathe
Hot-Vent Microbes: Looking Backward In Evolution For Future Uses
Myrna Watanabe | May 29, 1994 | 7 min read
They live--thrive, even--in boiling water! They feed on sulfur or hydrogen. They could be from one of the moons of Jupiter. In fact, their existence here on Earth has led scientists to realize that planets they hitherto assumed to be lifeless might support life. These thermophilic, or heat- loving, microbes--Archaea--are attracting a small but growing cadre of researchers and serious research funding from the United States governmen

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
