The proteasome helps epithelial cells set up KAMPs

N-WASP helps cancer cells open up

HIV’s kinesin chauffeur G audin et al. identify a type of kinesin that ferries HIV to the plasma membrane, helping the virus escape from macrophages. HIV reproduces inside T cells, killing them in the process. But the virus can also replicate in macrophages, which survive infection and serve as reservoirs of HIV. In T lymphocytes, new viral particles are born at the plasma membrane, but in macr...

SSX2IP helps the centrosome grow up

Catching augmin in the act K amasaki et al. observe links between microtubules within the mitotic spindle that might allow these microtubules to grow in the right direction. Most spindle microtubules extend from the centrosomes, and some sprout near the chromosomes. But researchers have discovered a third category of microtubules that grow within the spindle. The augmin complex and the -tubulin...

Functional Programming Helps Speed up MPICollective

This paper shows how functional programming techniques have been successfully applied to relieve a performance bottleneck in an MPI collective communication operation. A functional speciication for the improved operation is given, and an eecient version implementable in an imperative language is derived and proved correct. Experimental results on an IBM SP2 distributed{memory machine connrm the...
