Liverworts (class Hepaticae) are related to mosses. They grow in damp habitats and are found on the ground and moist rock surfaces. They have no true vascular tissue, but are attached to the ground by means of root-like rhizoids.  Liverworts can reproduce vegetatively by fragmentation of the thallus or by producing specialized cell masses called gemmae.   The central structures in this image are the reproduction organs. Magnification is 125x and represents a section of the plant 1 mm wide...

  • The patterns in smoke are studied by illuminating the smoke with a scanning laser. The laser shows the motion in a 2D plain that is easier to study than the 3D motion. The coils represent cross section of fluid vortexes created by the convection currents from the hot smoke rising in the cool air. The source of the smoke is a stick of burning incense.

  • Gypsum. Polarized light micrograph of a thin section of gypsum. Gypsum is a chemical sedimentary rock, composed mainly of hydrated calcium sulphate. It may grow as a crystal aggregate (as here) or in giant tabular crystals up to 1 meter in length. Gypsum is used in plaster of Paris, in Portland cement and as a flux in pottery. The most compact form of gypsum is known as alabaster. Sample collected in Penfield, New York.  Object size: 40 mm.

Obtained from the Devonian strata of New York.

  • Fragment of an Abalone shell; color enhanced scanning electron micrograph (SEM) of a section through an abalone (Haliotis sp.) shell. The shell is composed of layers of overlapping platelets of calcium carbonate crystals, or aragonite,  Between the layers are thin sheets of protein (not seen). This structure makes the shell much stronger than the materials would be in any other arrangement.  Abalones are edible mollusks found in warm seas. The thin layers of shell reflect light using the wave nature of light.  Each thin layer reflects a particular wavelength – together the layers reflect wavelengths of light that constructively interfere to create bright greens and blues. Magnification: x8000 when printed at 10 cm wide.
