Universal silver microscope

One of two ornate silver microscopes made by George Adams (1709-1773) of Fleet Street, London, for King George III (1738-1820). It is based on the 'Universal Double Microscope', described by Adams in 1746. It is made of brass and steel, covered in beaten silver.Photographed in the Science Museum, London, through its glass case.Use red/cyan anaglyph glasses to see in 3D (red over the left eye)

Beetle tracheas

Tracheal tubes are visible in this synchrotron x-ray phase contrast image (right) of a tenebrionid beetle (left). See: Alexander et al., “Increase in tracheal investment with beetle size supports hypothesis of oxygen limitation on insect gigantism,” Proc. Natl. Acad. Sci. USA 104(32), 13198 (August 7, 2007).

Comparative thickness of human hair

Credit: Anne Weston, LRI, CRUK. Wellcome image shows the difference in thickness of human hair between different ethnic groups. The strand of hair on the left is that of a Caucasian blonde female. The hair on the right is from an Asian male. Hair is normally comprised of three layers, the inner medulla, the cortex and the cuticle. The cuticle is the outermost layer and is comprised of numberous overlapping cells or scales. The cortex makes up the majority of the hair thickness. Interestingly, the inner medulla is not present in blond hair.Scanning electron micrograph
