  • SEM of a conodont tooth.  Acid etched from 500 million year old rock. Scientists are still unsure how these teeth were placed in most of the species.  Conodonts are extinct chordates resembling small eels maybe the size of the modern earthworm.  Classified in the class Conodonta. For many years, they were known only from tooth-like microfossils now called conodont elements, found in isolation. Knowledge about soft tissues remains relatively sparse. The animals are also called Conodontophora (conodont bearers) to avoid ambiguity.  This specimen was .5 mm wide and was collected in Ohio.

  • A SEM image of the edge of a leaf shows a calcium oxalate crystal. These crystals are found throughout the plant and are responsible for throat irritation when medical marijuana is smoked. Plants that have too many oxalate crystals are good candidates for modern THC extraction techniques. Calcium oxalate crystals in plants are called raphides. Humans have similar calcium crystals that can appear as kidney stones. These crystals help remove calcium build up in the tissues and make it undesirable for grazing animals to eat the plant.

  • 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: x1000 when printed at 10 cm wide.

These structures help to provide support and strength. The spaces within this tissue normally contain bone marrow, a blood forming substance.  Magnification is x40 when printed 10 cm wide.

  • Caffeine crystals. Colored scanning electron micrograph (SEM) of caffeine crystals (1,3,7-trimethylxanthine).   Caffeine stimulates the central nervous system (CNS), increasing alertness and deferring fatigue. It occurs in coffee beans and tea leaves. Magnification: 952x and the image is .12mm wide.

  • SEM of Meteorite from the Cretaceous-Tertiary (KT) extinction event, also known as the KT boundary, was a period of massive extinction of species that occurred about 65.5 million years ago. The spheres shown here represent material that was melted from a large meteorite impact. Flung high into the earth's atmosphere, these hot particles rained down, killing most life on the planet. These specimens are from Spain and were photographed at 145x magnification.

  • A cannabis seedling showing the first set of true leaves. Imaged with a scanning electron microscope (SEM). False color has been applied. The marijuana plant produces tetrahydrocannabinol (THC), the active component of cannabis when used as a drug. The filed of view in this image is 3 mm wide.

  • Colored-enhanced scanning electron micrograph (SEM) of a section through a xylem vessel in a cannabis stem. The xylem transports water and mineral nutrients from the roots throughout the plant. The walls of the xylem vessels are strengthened with lignin  loops, a woody substance that helps to support the plant. Magnification: x2200 when printed at 10 centimeters wide.

  • 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.

  • A close up of the seed leaf or cotyledon of a cannabis plant. Imaged with a scanning electron microscope (SEM). The surface of the cotyledon. The cotyledon is the scientific name for the fist two leaves the plant makes. In reality, these two leaves are actually folded up inside the seed, so this structure is often called the seed leaves. It is important that the seeding gets these leaves unfolded and oriented correctly quickly to start photosynthesis and start False color has been applied. The marijuana plant produces tetrahydrocannabinol (THC), the active component of cannabis when used as a drug. The filed of view in this image is 1.2 mm wide.
