‘Smarter Every Day’ explores how bacteria move to survive—and make us sick
In a recent episode of Smarter Every Day, YouTube sensation and host Destin Sandlin talks with Vanderbilt Professor Tina Iverson and Senior Research Associate Prashant Singh about bacterial “motors” and how they work in the microorganisms that make us sick. The video racked up more than 1.4 million views in its first day. Read MoreJul. 31, 2024

STOP the GAP: New cryo-ET package aims to fill in the ‘missing wedge’
Cryo-ET suffers from the “missing wedge” problem: as samples become more tilted, their thickness at the extremes is increased and sample penetration decreases. William Wan and collaborators describe the creation of a new subtomogram averaging package called STOPGAP. Read MoreJun. 3, 2024
