Natural Sesame Seed Science Image
Description:Natural sesame seed. Coloured scanning electron micrograph (SEM) of a natural (unhulled) sesame seed. Sesame (Sesamum indicum) is grown primarily for the seeds it produces. Magnification: x35 when printed 10 centimetres wide.
Normal feather and owl feather SEM Science Image
Description:Feather comparison of Swallow (Hirundo rustica) and Tawny owl (Strix aluco), scanning electron micrograph (SEM). Owls have the benefit of silent flight due to the filamentous extensions of their anterior barbules on their feathers. Most other birds including other raptors do not have this feather structure. This gives the owl an added advantage when swooping on its unsuspecting prey. Magnification x96 at 10cm wide.
Hogweed seeds (Heracleum sphondylium) SEM Science Image
Description:Hogweed, pair of seeds (Heracleum sphondylium), coloured scanning electron micrograph (SEM). Magnification x7.5 at 10cm wide.
Damaged human hair shaft SEM Science Image
Description:Damaged human hair shaft, coloured scanning electron micrograph (SEM). This can be caused by overheating the hair using curling tongs or hair straigheners, as well as chemical dyes, back combing and over brushing. Hair straighteners can get so hot that the moisture inside the hair shaft can reach boiling temperatures, leaving the hair seriously damaged. The cuticle or scales which cover the outside of each hair shaft can be stripped off. The hair will become brittle, dry and frizzy causing breakages along the shaft. Magnification x431 at 10cm wide
Full Set of Male Chromosomes SEM Science Image
Description:Set of human chromosomes, coloured scanning electron micrograph (SEM). Chromosomes are a packaged form of the genetic material DNA (deoxyribonucleic acid). The DNA condenses into chromosomes during cell replication for ease of division and transport into the new cell. A complete set of chromosomes is known as a karyotype. In humans, there are 46 chromosomes, consisting of 23 chromosome pairs. This image is of human male chromosomes and shows the x & y sex chromosomes (Pair No. 23)
Lactobacillus casei bacteria (SEM) Science Image
Description:Lactobacillus casei bacteria. Scanning electron micrograph (SEM) of the bacteria Lactobacillus casei. L. casei is a bacterium that is found in the human intestines and mouth. It's most common application is in the production of dairy products, specifically yoghurts. Some of the L. casei bacteria are stated, by their producers, to be probiotic and beneficial to the intestinal microbial balance of the host but this has yet to be proven conclusively. Magnification x50000 (x12500 at 10cm wide).
Human Skin Cells (SEM) Science Image
Description:Human Skin Cells. Scanning electron micrograph (SEM) of the surface layer of the human skin, the epidermis. The outer layer of the epidermis (stratum corneum) is a tough coating formed from overlapping layers of dead skin cells which are continuously sloughed off and replaced with cells from the living layers beneath. The skin is the largest organ of the body and protects from injury and dehydration as well as assisting with the regulation of body temperature. A small number of yeast cells are visible (yellow). Magnification x7920 (x1950 at 10cm wide).
Silkworm Cocoon Silk Fibres (SEM) Science Image
Description:Silkworm cocoon silk fibres. Scanning electron micrograph (SEM) of silk fibres. The silkworm is the larva or caterpillar of the silkmoth which has been domesticated from the wild silkmoth Bombyx mandarina. The domesticated silkmoth (Bombyx mori) is now completely dependent on human rearing as it does not occur in the wild but it can still breed with the wild silkmoth Bombyx mandarina and often produces hybrids. The larva prefers to eat leaves of the white mulberry but will eat leaves from other mulberry trees. They are veracious eaters and molt 4 times before going into the pupa phase of their life cycle. This is when they spin silk from their salivary glands and wrap themselves in it making a cocoon for protection when they are nearly motionless and most vulnerable. Each cocoon can have a thread of raw silk from 300 to around 900 metres long. Magnification x4000 (x1000 at 10cm wide).
Pollen (Viburnum rhytidophyllum) SEM Science Image
Description:Viburnum pollen grain. Scanning electron micrograph of a pollen grain of the plant Viburnum rhytidophyllum. This plant is very hardy and can tolerate temperatures as low as -15 degrees centigrade. It is a tall, vigorous and erect evergreen shrub which grows up to 5 meters in height. The leaves are corrugated and oblong to lance shaped up to 20cm long. It produces white tubular flowers in dense umbel-like cymes about 20cm across and then red berries which turn black. Magnification x12940 (x3200 at 10cm wide).
Potato Leaf ts (SEM) Science Image
Description:Potato leaf. Coloured scanning electron micrograph (SEM) of a transverse section of a potato leaf (Solanum tuberosum). The upper and lower surfaces of the leaf are covered in a single layer of closely packed cells called the epidermis. Below the upper epidermis is a layer of palisade parenchyma cells containing many chloroplasts. Beneath this layer is the spongy mesophyll which has large intracellular spaces for gaseous exchange. At the bottom is the lower epidermis, a single layer of closely packed cells where the stomata control gas exchange within the spongy mesophyll. Magnification x1260 (x262 at 10cm wide).
Male bedbug intromittant organ (SEM) Science Image
Description:Male bedbug's sexual organ. Scanning electron micrograph (SEM) of the intromittant organ or sexual organ of a male bedbug (Cimex lectularius). During mating, the male pierces the body wall of one of the female's abdominal segments with this organ and deposits his sperm in a sac. The sperm then migrate through the body cavity to the seminal conceptacles, where they are stored ready for later fertilisation. Among the insects, this so-called traumatic insemination is unique to bedbugs and related families. Two to four generations of young can be bred yearly. The bedbug is a nocturnal parasite that feeds on the blood of humans and other warm-blooded animals. It inhabits human dwelling places, living in mattresses, upholstery and flooring. Magnification x2625 (x545 at 10cm wide).
Polar Bear Hair (SEM) Science Image
Description:Polar bear insulating hair. Coloured scanning electron micrograph (SEM) of a cross-section through shafts of insulating hair from a polar bear (Ursus maritimus). This has revealed the hollow structure of the hair that gives it its insulating properties. The hollow in the centre of the hair contains air, which is not a good conductor of heat. This insulates the polar bear from the extreme cold of its Arctic habitat. The air also helps to prevent the hair matting, which helps the polar bear shake itself dry. The hair is also oily to repel water. Insulating hair forms a coarse outer hair layer over underhair. Magnification x1150 (x285 at 10cm wide).
Yew Leaf Stomata (SEM) Science Image
Description:Yew stomata. Coloured scanning electron micrograph (SEM) of stomata (pores) on the surface of the leaf of an English yew (Taxus baccata). Stomata are pores which regulate gas and water exchange between the leaf and the atmosphere. During the day they open (as seen here) to allow the exchange of gases during photosynthesis, closing at night to prevent water loss. They are opened and closed by two bordering guard cells. Yew is a long-lived poisonous tree which inhabits cool, hilly areas throughout Europe and northern Asia. Magnification x4260 (x1050 at 10cm wide).
Water Bear or Tardigrade Science Image
Description:Water bear (or tardigrade). Scanning electron micrograph of a water bear (echiniscus granulatus). These tiny invertebrates live in coastal waters and freshwater habitats, as well as semi-aquatic terrestrial habitats like damp moss. They require water to obtain oxygen by gas exchange. In dry conditions, they can enter a cryptobiotic tun (or barrel) state of dessication to survive. Water bears feed on plant and animal cells and are found throughout the world, from the tropics to the cold polar waters. When in the dessicated state they can survive extreme environments including up to 10 days in the vacuum of space and are classed as extremeophiles. Magnification x2100 (x520 at 10cm wide).
Fruit fly (Drosophila funebris) Science Image
Description:Fruit fly. Coloured scanning electron micrograph (SEM) of a fruit fly (Drosophila funebris) on an apple. Its compound eyes (red) are seen and its wings are outstretched. Fruit flies are widely used in genetic experiments, particularly in mutation experiments, because they reproduce rapidly and their genetic systems are well understood. Magnification: x20 when printed at 10 centimetres wide.
