He took a series of images of the 1.2-millimeter-diameter eggs and combined them with photo-editing software. The white halos outline the lids through which nymphs emerge. [Less] [Link to this slide]

A section of the leg of a female hoverfly, stretching several hundred microns across, bears two pulvilli, adhesive structures that enable the insect to stick to a surface. The pulvilli, seen here as large, orange appendages at the upper right that form a V shape, are connected to the leg by a spring system (blue areas), which consists mainly of the protein resilin. Jan Michels of Kiel University in Germany made the photograph of Eristalis tenax as part of a study on the potential of confocal laser scanning microscopy to furnish three-dimensional images of resilin-containing insect body parts.

This thin, twisted, five-centimeter-long pod resembles the tail of a scorpion, giving the plant that produced the pod its name. Viktor Sykora of Charles University’s First Faculty of Medicine in Prague does microphotography of plants as a hobby and has published a book on the topic. ...[More]

Ultraviolet light causes the mushroomlike fruiting bodies of myxomycetes, or slime molds, to luminesce with a ghostly aura. Dalibor Matýsek, a mineralogist at the Technical University of Ostrava in the Czech Republic who images biological objects as a hobby, used “focus stacking,” combining more than 100 scanned images to form a three-dimensional picture of the 4.4-millimeter-tall Arcyria stipata....[More]

Two lobes of the corona of the rotifer Floscularia ringens , spanning 300 microns, emerge from a protective tube. The cilia at the edge of the corona move in a fast, steady, wavelike motion called a metachronal wave, creating water currents that move food to the rotifer’s mouth....[More]
Two lobes of the corona of the rotifer Floscularia ringens, spanning 300 microns, emerge from a protective tube. The cilia at the edge of the corona move in a fast, steady, wavelike motion called a metachronal wave, creating water currents that move food to the rotifer’s mouth. The tube consists of reddish-brown circular pellets that the rotifer forms in a cilia-lined socket. A new pellet forms at the center of this first-prize photograph taken by Charles Krebs of Issaquah, Wash. Once the pellet reaches the appropriate size, the rotifer retreats into its tube and, on the way down, quickly but carefully “plants” the new pellet along the top edge of the tube.

A single mast cell has infiltrated the eye surface in response to a perceived invasion by a foreign substance. Mast cells, which contain vesicles of histamine ( red specks ), are among the immune system’s first responders, attracting other immune cells to the site of an infection....[More]
A single mast cell has infiltrated the eye surface in response to a perceived invasion by a foreign substance. Mast cells, which contain vesicles of histamine (red specks), are among the immune system’s first responders, attracting other immune cells to the site of an infection. Here the release of histamine is helping to separate collagen fibers through which the mast cell is migrating. Donald W. Pottle of the Schepens Eye Research Institute in Boston took this confocal microscope image.

Kathryn R. Markey has a thing about scallop eyes. So she set about recruiting a spat bay scallop from the Luther H. Blount Shellfish Hatchery at Roger Williams University in Bristol, R.I., to show the rest of the world their “majestic eyes”—the blueberrylike circles at the borders of the shell....[More]

Blount Shellfish Hatchery at Roger Williams University in Bristol, R.I., to show the rest of the world their “majestic eyes”—the blueberrylike circles at the borders of the shell. This exemplar of Argopecten irradians went under a stereomicroscope in the university’s Aquatic Diagnostic Laboratory, where Markey works, to have its portrait taken. [Less] [Link to this slide]

Radiolaria, single-celled, amoebalike creatures that inhabit all the world’s oceans, sport radially arranged protrusions called axopodia that here resemble buttons. The axopodia help the critters to float and ingest food. To produce the picture of this 120-micron-long radiolarian skeleton, Christopher B. Jackson of Ikelos in Switzerland took 15 light-microscope images, captured each one at a different focal plane and then combined the set to achieve a sharp image. [Less] [Link to this slide]

Add Commentmonkeys in rooms typing away madly CAN produce amazing treasures, as we can see. Isn't random selection great to look at? Who's a better artist than Mother Earth?
Reply | Report Abuse | Link to thisWouldn't it be awesome to change the world for the better with just two sheets of rolled up paper!
Reply | Report Abuse | Link to thisLETS DO IT! -- Take one sheet and role it up making a tube (just tiny pieces of tape to hold).
At the center of the tube start marking small arrows away from you at an angle spiraling to the end (mark that end south.
Go back to center and in the same direction start marking arrows to the other end (mark that end north.
Do the same with the other sheet but make it a bit bigger so one will fit inside the other. You have just made two pretend bar magnets!
Taking the two magnets insert the north pole into the other north pole. Note the arrows are clashing (repelling).
Now insert the north pole into the south pole and the arrows are melding (attracting). This is where it gets real interesting! Looking at the north pole end, the arrows show the direction of magnetic force to be counter clock wise. Turning it around the south pole shows the arrows or force to be clock wise. Now "what is this" one direction has turned into two directions at the same time! yes but, yes but you say Its just how you look at it Two directions at the same time indeed.
OK lets bend one around (horse shoe) and look at both ends at the same time. Don't miss any thing here because this is how the world works.
Note that the forces meld into a figure eight and that is how every thing in this world is held together.
The cell has a nucleus with chips (nuclei) of itself in orbit.
Reply | Report Abuse | Link to thisHorizontally to the nuclei orbit, chips are flung out to produce a pole on each side of the orbit.
The cell Earth with one orbit, rock with two some minerals and all life with three and a new species (brain) with four.
By chewing pollen the bee produces a glob of wax. Immediately after the placement, the saliva or water of the glob interacts in repelling the wax away from the glob's nucleus.
The wax takes on the shape produced from the three nuclei orbits of the water nucleus. What is called evaporation leaves an empty six pole or six sided wax structure.
What on earth would have ten poles? Ghost, spirit, bigfoot, ufo? hmmmmmmmm

PS -- The Earth has its nucleus nuclei orbiting "equatorially" from West to East. Through centrifugal force nuclei spiral horizontally away from the orbit producing our North (counter clockwise) and South (clock wise) poles.
The text book diagram showing the Earths Magnetic Field is perhaps "wrong"!
