A new study finds parallels between the brain architecture that drives locomotion in sea slugs and that of more complex segmented creatures with jointed skeletons and appendages. 

In a study reported in the journal Chemical Science, researchers developed a new method to determine how antibiotics with specific chemical properties thread their way through tiny pores in the otherwise impenetrable cell envelopes of Gram-negative bacteria.

Klaus Schulten, professor of physics, chemistry, and biophysics and computational biology, and colleagues this week presented the first computer simulation of an entire life form, a virus. The full study will appear in the March issue of the journal Structure.
