Photo: Ori Fragman, Hebrew University Hordeum spontaneum, the plant studied for BARE-1 retroelements. With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c
NAS Honors Sagan And 14 Other Science Achievers

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

Researchers Receiving MacArthur Fellowships Demonstrate 'Capacity To Make A Difference'
Bruce Anderson | Sep 14, 1997 | 6 min read
PRIZE WITH A PRICE: Science historian Peter Galison has taken some ribbing from his family since being named a MacArthur fellow. One could almost pity Peter Galison. A historian of science at Harvard University, Galison is one of seven members of the scientific community among the 23 recipients of this year's John D. and Catherine T. MacArthur Foundation Fellowships. The coveted five-year awards provide unrestricted support plus health insurance to talented individuals, with no reports or proj
Ribozymes: Hearkening Back to an RNA World
Jeffrey Perkel | Sep 15, 2002 | 9 min read
Illustration: Ned Shaw LIKE MOLECULAR TOY-MAKERS, ribozyme researchers create tools with evolutionary, diagnostic, and therapeutic applications. Nearly 20 years ago, Tom Cech and Sidney Altman discovered that some naturally occurring RNAs could perform enzymatic reactions, earning these researchers the 1989 Nobel Prize in chemistry. Scientists have now identified several examples of RNA enzymes, or ribozymes. Most make or break the phosphodiester bonds in nucleic acid backbones, but some
