A dozen plastic bags of components, washers etc from UK company Labcrafter to build a 3-D printed microscope designed by OpenFlexure. Image from Labcrafter, at https://labcrafter.co.uk/products/openflexure-microscope
Dawn redwood trunk, with bark starting to grow around the metal banister of a fire escape.
Motif plot showing which amino acids are enriched or depleted in the residues next to the phosphorylated Serine or Threonine, which reflects the preferences of the protein kinase enzymes that do the phosphorylation. Those enzymes seem to work in alternate shifts, because acid residues (D/E) flank the rhythmic phospho-dawn sites that are most phosphorylated at ZT0 before dawn. Many of the evening-peaking sites are followed by Proline (P), characteristic of GSK3b and the cell-cycle kinases. (from Figure 5C)
Graphs showing that rhythmic RNAs peak at all times of day but rhythmic proteins mostly peak in day-time, and many Phospho-sites peak at ZT0, just before dawn (from Figure 2).
A cell image from electron microscopy. Its colour-coded parts show how tiny the cell is. The single chloroplast, here coloured green, occupies more than half the cell.

A mossy tree trunk that has grown over a 1kV power line, just the edge of the insulators sticking out of the bark, and the cables.
