Richard Losick and Jonathan Dworkin In 1918, German embryologist Hans Spemann took an early newt embryo and removed some cells that were destined to become skin. He transplanted…
Figure 1 Communication between neurons occurs at specialized structures called synapses, where neurotransmitters released by synaptic vesicles activate receptors on the postsynaptic neuron to elicit chemical and electrical…
The figure shows a field of sporulating cells the outlines of which are stained red with a membrane strain. Red lines across the short axis of the cells…
A recent study by Kishi et al. shows how research programs can take unexpected directions. The authors wanted to study how small parts of neuronal processes become specialized…
Ben de Bivort Figures Although microarray technology is wildly popular among biologists, even its biggest fans are sometimes overwhelmed by the sense of having too much information. This…
Andrew Murray and Vahan Indjeian Errors in chromosome segregation lead to disease and death. To prevent such errors, sister chromatids are held together with the protein complex cohesin,…
View Movies and Figures A 360° view of a segregated neuromuscular junction (muscle surface is shown in red). The animation provides a closeup of the green bulb-tipped axon…
The image shows a pair of adjacent sporangia each of which consists of a large mother-cell (green) and a forespore (circular chambers outlined in red). The green color…
A paper in the August 24 issue of Proceedings of the National Academy of Sciences, U.S.A., from the Kleckner lab provides a new theory of chromosome function that…
Biological systems are robust; they function reliably despite disruptions. Internal fluctuations occurring on a microscopic scale or changes in external conditions, such as temperature, pose challenges to system…
