Designing a Shorter Vertical Leg for Sanitary Steam TrapsSteam traps are part of a steam-in-place system. The current design allots 18 in. of vertical leg for condensate backup. A design with a sensitive bellows has been proven in laboratory tests to need only 6 in. of vertical leg during the 15 min. of 121?C sterilization. Loads of 1 to 27 lb/h are covered by the capability of the new trap, equivalent to required steam for vessels 20 to 40,000 L.

A Statistical Method to Account for Plate-to-Plate Variability in Multiple-Plate Bioassaysby James D. Williams, Virginia Polytechnic Institute and State University, Jeffrey B. Birch, and Steven Walfish Statistics don't lie, but if you don't include appropriate data, the resulting statistical analyses can be misleading. In biopharmaceutical development, if the variability from several different microplates is not addressed, assays testing the relative potency against a standard can be inaccurate. A statistical method that accounts for plate-to-plate heterogeneity is needed ? and presented here.

Final Word: The National Academies' Guidelines for Human Embryonic Stem-Cell ResearchOn April 26 the National Academies of Sciences and the Institute of Medicine released guidelines for human embryonic stem (hES) cell research, the result of eight months of deliberations by a human research ethics committee I co-chaired with MIT's Richard O. Hynes. Composed of scientists, physicians, lawyers, ethicists, a social scientist, and a private citizen, the committee held a two-day public workshop and numerous meetings. We also reviewed international guidelines, policies, and procedures in this field.
