Untangling Neuronal Calcium Signaling
Amy Adams | Jan 20, 2002 | 10 min read
From the very moment of conception, calcium plays a pivotal role in fetal development. It rushes in as a wave around the egg to herald the sperm's arrival, binding to proteins that help kick off the whole developmental process. From this first influx, calcium continues to play a critical role in how the body's cells respond to outside signals. Calcium tells muscles to contract and nerves to release neurotransmitters, and is at least part of the signal that helps people form and retain memories.

Three of the 13 awards this year are going to astronomers, including the academy's highest honor--the Public Welfare Medal--which is being given to Carl E. Sagan, 59, David Duncan Professor of Astronomy and Space Sciences at Cornell University, Ithaca, N.Y. Every year, NAS presents this medal (the only award without an accompanying cash prize) to an individual who has made extraordinary use of science for the public good. Perhaps

Epigenetics: Genome, Meet Your Environment

©Mehau Kulyk/Photo Researchers, IncToward the end of World War II, a German-imposed food embargo in western Holland – a densely populated area already suffering from scarce food supplies, ruined agricultural lands, and the onset of an unusually harsh winter – led to the death by starvation of some 30,000 people. Detailed birth records collected during that so-called Dutch Hunger Winter have provided scientists with useful data for analyzing the long-term health effects of prenat
