The Stanford team believes that Mapper will be invaluable as scientistscontinue toward their goal of determining the entire sequence of geneticletters that make up the human genome. "The maps we've made using this program are among the highest-resolutionmaps that have been ma...New Discovery About Genes Has Implications For Genetic Therapy
...f introns found in higher organisms." Lambowitz believes that the introns are "parasites" on the genome, and behave similar to the way retroviruses inhabit an organism. He suggested that retroviruses might even have evolved originally from these kinds of introns. "Their (the introns') only function is ...Mutate Or Die: New Polymerase Gives Desperate Yeast An Option
... it's better to mutate than to die." Lawrence believes that this process accounts for 2/3 to 3/4 of all spontaneous mutations in yeast, including basesubstitutions, the type often seen in cancer cells or oncogenes like p53 or ras in humans. His laboratoryis now searching for counterparts in humans to...Nitric Oxide May Hold Key To First Treatment For Deadly Form Of Malaria, Duke Scientists Report
...hough the discovery was made in bacteria, the team believes that humancells also use NO molecules as a genetic signaling mechanism. "It appears that life uses NO ubiquitously," said the study'sleader, Dr. Jonathan Stamler, a cardiologist and pulmonologist.

Terwilliger believes that if countries realize they need trees for growth and survival, they can capitalize on native species and return the cleared land back to its native foliage. Terwilliger starts her research on a species by obtaining specimens in the rain forest an...Researchers Develop Model Using Birds As Indicator Of Wetlands Health

Coleman believes this type of index will be a useful tool toprovide a quick comparison among wetlands as well as a way tomonitor the health of one particular wetland over time. As part of his Ph.D. research, he also hopes to refine themodel and extend his work with b...Pinpoint Gene Control Holds Promise For Nervous System Studies
...activating the extra genes to produce NGF.The team believes this is the first permanent geneticmodification in the central nervous system of an adult mammal. The work gives scientists the ability to study genes in a waythey've never been able to before.
