Synthetic DNA shows that four bases might not be the only way for life to go

I haven’t yet been to see the Snipe (Gallinago gallinago) living on the edge of our village pond, but a visit to RSPB Fen Drayton today allowed us good views of a pair roosting and then feeding on the little islands right in front of the Coucher Hide there. This species is incredibly well camouflaged … Continue reading "A pair of Snipe at RSPB Fen Drayton"

Fluorescence unmasked

While synthesizing fluorescent dyes like these, Jon Grimm of Janelia Research Campus often has to mask or “protect” parts of his molecules with functional groups that are less reactive. This step allows him to modify one part of the dye molecule without undoing the work he did on another. The protected versions of the molecules are colorless. But when Grimm adds sodium hydroxide or tetra-n-butylammonium fluoride (TBAF) to the protected molecules, they lose their protecting groups... Читать дальше...
