Quantum Dots Get Smaller
Karen Heyman(kheyman@the-scientist.com) | May 8, 2005 | 6 min read
For all the hype about nanotechnology, sometimes small isn't quite small enough.
Nanotech Dreams
Jeffrey Perkel | Mar 3, 2002 | 9 min read
Nanotechnology hit the big time in July 1995, when it debuted on the television show, The Outer Limits. In an episode entitled "The New Breed," a scientist develops nanorobots capable of repairing damaged cells and correcting physical defects. But, like any good morality play, the experiment goes horribly wrong, turning a panacea into a nightmare. Clearly, nanotechnology makes for good science fiction, but scientists have been working to make it an interesting reality, too. Nanotechnology refers

Synthetic mRNA encoding CKI, mutant CKI (K > R), or Xwnt-8 was injected at the eight-cell stage into one ventral vegetal blastomere. Embryos injected with CKI or Xwnt-8, but not inactive CKI (K > R), developed complete secondary dorsal axes.

DEINO-MITE CLEANUP In 1956, investigators discovered a potentially invaluable cleanup tool in an unlikely place. A hardy bacterium called Deinococcus radiodurans unexpectedly thrived in samples of canned meat thought to be sterilized by gamma radiation. The b
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
NAS Honors Sagan And 14 Other Science Achievers
Neeraja Sankaran | Apr 17, 1994 | 8 min read
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
