The molecular dynamics of three different 

 leukotrlene (LTC4, LTD4. and LTE4) molecules 

 portrayed with a new supercomputing 

 visualization technique called "ghosting. " Dense 

 shadows represent the configurations in which 

 the molecules spend a greater amount of time, 

 while the range of molecular movement is shown 

 by the extent of the dot patterns. 



information. Communicating their data via the 

 Internet, these groups compared three-dimen- 

 sional MRI to standard X-ray mammography for 

 the detection of early breast cancer, and found 

 that the new technique revealed early tumors that 

 could not be detected by mammography.
