Sensory Biology Around the Animal Kingdom

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.

Glial cells were once considered neurons’ supporting actors, but new methods and model organisms are revealing their true importance in brain function.
Scientists Strike a Cord

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. Eng et al., "Defects in sensory axon growth precede neuronal death in Brn3a-deficient mice," J Neurosci, 21:541-9, 2001.) Somewhere in the 200 million bases of the human ge

Surpassing the Law of Averages

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
A Paradigm Shift in Stem Cell Research?

Laywell, UT MemphisMultipotent clones of cells derived from the adult human brain With the promises and challenges of stem cell research in the headlines, visions of artificial livers dance in the public's eye. Bioethicists, politicians, and citizens alike continue to debate whether public funds should be used to obtain cells from human embryos and fetuses. On the scientific front, however, the implications of stem cell research are even more profound than offering replacement parts.
Illuminating Behaviors
Douglas Steinberg | Jun 1, 2003 | 6 min read
Courtesy of Genevieve Anderson If not for Nobel laureates Thomas Hunt Morgan, Eric R. Kandel, and Sydney Brenner, the notion of a general behavioral model might seem odd. Behaviors, after all, are determined by an animal's evolutionary history and ecological niche. They are often idiosyncratic, shared in detail only by closely related species. But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t
Deciphering How the Sexes Think

Editor's Note: This is the second article in a series on sex-based differences in the biology of males and females. Future articles in the series will cover sex-based differences in genetics, autoimmunity, and drug metabolism. Stereotypes aside, women and men do process information in singular ways. In the past, tests that tried to pinpoint those variations were fraught with inconsistencies and irregularities. But now, by studying the brain itself, researchers are learning that the sexes use dif
The Genetics of Society

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.
