  • Bird red blood cells collected from a Baltimore Oriole (Icterus galbula).  Colored scanning electron micrograph (SEM) of red blood cells (erythrocytes, red) from avian tissue. These cells contain hemoglobin, a pigment that allows them to carry oxygen around the body. Non-mammalian red blood cells (such as these) are oval (discoid) in shape and contain a cell nucleus. Human red blood cells are disc-shaped and do not have a cell nucleus. Magnificationof image is 1960x and the image is  80um  wide. .

  • Needle playing a record. Colored scanning electron micrograph (SEM) of the needle (stylus) of a record player in a groove on a record. A record is used to store sound. It is produced by a machine with a head which vibrates in time to the sound being recorded. This cuts a groove in the record which varies according to the vibrations. A needle can then reproduce these vibrations as it runs along the groove and these, when amplified, produce the original sound.  This is a stereo record.  The needle in contact with the record is a LP needle, or a long play needle designed for stero use.  The spair needle pointing up is a 78 RMP needle - not the different angles.  This record is designed for 45 RPM.

  • A false color SEM image of a Calcium oxalate crystal.  Even a small dose of calcium oxalate is enough to cause intense sensations of burning in the mouth and throat.  Commonly found in popular houseplants, such as Dumbcane, the crystals effects or symptoms may last for a week or more, making calcium oxalate crystals a non-desirable ingredient in medicinal cannabis.  It is surprising that calcium oxalate is rarely discussed in literature about medical marijuana (cannabis).  There crystals are fairly common in plants, as they make it hard for grazing animals to eat the plant. Image is 20 um wide.

  • False color scanning electron microscope image of a vinyl record.  A record is used to store sound. It is produced by a machine with a head which vibrates in time to the sound being recorded. This cuts a groove in the record which varies according to the vibrations. A needle can then reproduce these vibrations as it runs along the groove and these, when amplified, produce the original sound.

  • Surface of  a mature cannabis stem. The image is 6mm wide.  The different layers of the stem have been given different colors.  The layer that is several cells below the skin is the section of thick-walled fiber cells.  This highlights one potential uses of cannabis: an excellent source of fibers for paper, rope, and fabric.  The legalizing of cannabis in the United States opens research in this very profitable aspect of the plant. Field of view of this image is 2 mm.

  • A cross section of a mature stem.   The different layers of the stem have been given different colors.  The layer that is several cells below the skin is the section of thick-walled fiber cells.  This highlights one potential uses of cannabis: an excellent source of fibers for paper, rope, and fabric.  The legalizing of cannabis in the United States opens research in this very profitable aspect of the plant. Field of vie of this image is 1 mm.

  • Scanning Electron Microscope (sem) image of heroin (diamorphine).  Heroin is a powerful narcotic  and painkiller that is derived from morphine. Its use in medicine is restricted because it is highly addictive after only a short period of use. Heroin is abused as a recreational drug. The body develops tolerance to the drug quickly and larger doses are needed to achieve the same effect.  The calibration bar is 10 um and the magnification is 802 x. In this image the blue colors represent contaminants.
