| The state capital of Wisconsin, where the third annual meeting of the RNA Society was held in May, 1998, is a lovely small city. |

- MATERIALS SCIENCE: Mammalian Cells Spin a Spidery New Yarn
Spider dragline silk is stronger than Kevlar and stretches better than nylon, a combination of properties seen in no other fiber. Researchers report splicing dragline silk genes into mammalian cells and showing for the first time that harvested recombinant proteins can be spun into strong, lightweight fibers.
- CELL BIOLOGY:
Stripping the Nucleolus Down to Its Proteins
Scientists have identified 271 proteins in a compartment of the cell nucleus called the nucleolus--a first step toward fully deciphering this organelle, a critical element in the construction of ribosomes, which go on to make proteins. With scientists now debating the nucleolus's role in additional functions, including cell cycle regulation and gene silencing, this starter list of proteins--30% of which are uncharacterized--offers plenty to chew on.
- FORENSIC SCIENCE:
Fingerprinting Doesn't Hold Up as a Science in Court
When the U.S. Supreme Court set new standards 9 years ago designed to keep "junk science" out of the courtroom, few would have guessed that evidence based on one of the oldest and most widely used forensic techniques in the world might be in jeopardy. But earlier this month, a federal judge ruled that old-fashioned fingerprinting doesn't meet the Supreme Court's standards. The ruling won't knock fingerprint examiners out of the courtroom, but it may limit the claims they can make. And it opens the way for challenges to the scientific credibility of ballistics and other forensic techniques.
