UF researchers develop tiny tool kit to study genes and unhealthy cell
...ll the information they need to identify the genes behind diseases ranging from diabetes to heart disease. Before researchers can turn the wealth of data provided by the Human Genome Project into new medical treatments, they'll need tiny tools to rearrange genes or gene parts and monitor the impacts. Now,...Key DNA enzyme can tolerate more mutations than expected
...nty-five years ago, Loeb theorized that the engine behind cancer's devastation was a mutator phenotype, in which there is an increasing rate of errors in DNA replication as a tumor grows. Only within the last few years have experiments shown Loeb's theory was correct. His goal now is to find ways to slow th...Five Seattle scientists selected as Howard Hughes Medical Institute investigators

"Overall, understanding this protein will further ourunderstanding of how to maintain chromosomes and to correctgenetic defects," said Kowal...Memory mechanism found at nerve cell connections in the brain
Scientists have identified a novel mechanism behind the decrease in strength of synapses in the brain, a process that leads to the creation of memories and their long-term storage. The increase or decrease in strength among synapses, and subsequent changes in memor...Virtual reality tool quantifies physics of a doctor's touch
