Pollen bring light into the darkness

A way of classifying pollen species is by monitoring auto fluorescence images of pollen grains. Several components of the exine (i.e. the outer layer of the pollen wall) show conspicuous auto fluorescence in the pollen grain.

What is scabies?

Scabies is an infection of the skin caused by a scabies mite. The Latin name for this is 'Sarcoptes scabiei'.

The females of the scabies mite dig small passageways in the top layer of the skin and lay their eggs in it. These eggs come out after three to four days. The animals are grown-up within 18 days. The faeces, the secretions, the eggs and certain other substances cause an allergic reaction to human skin. This reaction causes itching, blisters, bumps, redness and scaling. With a first infection, it takes two to six weeks until these reactions are visible/palpable.
