The image of the young Pope's head is superimposed on the Pope in the Popemobile.
Plot of the change in mRNA reads caused by deleting H-NS in both stationay phase and exponential phase.
Plots showing that H-NS excludes protein assemblies from a larger fraction of the cell compared to a deletion strain.
Plots showing that Dps diffuses more slowly in stationary phase.
Comparison of what parts of the genome contact each other and what parts are bound to H-NS. Plots show high correlation.
Cartoon showing H-NS pinching the DNA together in stationary phase.
Processed Hi-C maps of the E-coli genome.
Hi-C contact maps of the E. coli genome.
ChIP-seq plots of HN-S density across the genome show similar patterns in exponential phase and stationary phase.
Power spectrum of a trapped bacterium. Despite the rod-like shape of the cell, the power spectrum can be well fit by the function that describes the power spectrum of a sphere.
Stiffness vs diameter plotted for similarly sized beads made of either silica or polystyrene trapped at constant laser power. Stiffness depends both on size and material.
alamarBlue assay shows cells maintain metabolic activity for months after glass encapsulation.
A cartoon of bacterial cells aligned over a photodetector for increased efficiency.
Three bacteria are shown. The first is wt, and it scatters little light. The second two are coated in silica and scatter much brighter light beams.
A field of glass-coated E. coli cells are able to focus pillars of light when illuminated from the side.
A picture of the Corinthian from the Sandman series.
Tweet by Yglesias: I am torn: On the one hand, the absolute worst people in the Democratic Party love Tim Walz which strongly suggests he is bad. On the other hand, these people are idiots so maybe they are misjudging the situation.
Dps dodecamers bind two parallel strands of DNA.
Figure showing that Dps binds supercoiled DNA faster than relaxed DNA.
Cartoon of how we immobilized supercoiled and relaxed DNA side by side.
An image showing how Dps (red) likes to bind to supercoiled plectonemes in DNA (black).
