After a long winter and a short summer, I was amazed to see that the new Dino-lite Edge Series of handheld digital microscopes have already been on the market for over nine months. Out of curiosity, I took a look at the sales figures to see how they had done. Equally, to my amazement, the AM4815ZT ranked sixth for total sales of all Dino-Lite sales and third among all industrial models.
In other words, the AM4815ZT, with its new Extended Depth of Field (EDOF) benefit is highly successful. It outsells its sibling Edge series models by a factor of six times!
Originally, the Edge Series models were introduced in response to customer feedback. They all include a greater range of magnification (5x-1140x), even greater image resolution, longer working distance and the least aberration and vignetting of the entire Dino-Lite range.
Two important benefits were also added to individual Edge models:
- On-screen magnification display – AM4515ZT and AM4515ZTL
- Extended depth of field – AM4815ZT and AM4815ZTL
Curiously, in spite of customer feedback regarding on-screen magnification, sales of the AM4515ZT/ZTL have been tepid, at best.
What has become clear is that customers have a genuine need for EDOF. Useful for achieving clear images in a more vertical plane, such as bolts, holes, fabrications among others, the AM4815ZT and AM4815ZTL actually has a small electric motor inside the unit. When activated, the motor rotates the magnification wheel in 11 equal, minute, increments, stopping and capturing an image at each point.
It’s brilliant….and it works!
The only drawback to the Edge Series is that they are not Mac compatible, but given the industrial focus this appears not to be a major issue.
Dino-Lite have suggested that they may introduce the EDOF on more models although we have no information on timing. You can view the product details of the AM4815ZT by clicking here.
Following my last blog post on the Harvard School of Public’s Health study on bees and neonicotinoids, we received a comment from ‘George Citizen’ that leads me to amend my last blog post.
George cited an excellent article by Randy Oliver in which Randy challenges both the underlying assumptions and the manner of the Harvard study. His article forms an object lesson in critical analysis, how to conduct a genuinely professional study as well as shedding more light on the debate round Colony Collapse Disorder (CCD).
As I constantly tell my kids, “Don’t believe everything you read on the internet. Check your sources, cross- check them and then form your own opinions.”
In this I failed…….”Sorry, kids!”
Over the past few years in our own small way, we have tried to support beekeepers in their continuing fight against colony collapse disorder (CCD). We sponsor microscopy seminars at various beekeeping conferences. We sell a Beekeeper Special microscope package for nosema diagnosis and other hive infections. We have learnt that no one has been able to pinpoint the reason for CCD and that the arguments are many and manifold.
Most of all we have learnt the power of Commerce over Common Sense.
For several years, a suspect in the hunt for the CCD culprit, has been neonicotinoid pesticides. Neonicotinoids are neuro-active insecticides, similar to nicotine. They include acetamiprid, clothianidin, imidacloprid, nitenpyramnithiazine, thiacloprid and thiamethoxam. Of these, imidacloprid is far the most widely used pesticide throughout the world. Developed by Bayer, it is used in countless different brands and has a truly global impact.
Since 2012, research studies conducted in both Europe and the US have found compelling evidence that neonicotinoids adversely affect bees. The American Bird Society published a review of no less than 200 related research studies and advocate for a ban on neoinsectinoids due to their toxicity to birds and other wildlife. In January, last year, the European Food Safety Authority published a report confirming the toxicity of neonicotinoids and furthermore, that some of the research on which regulatory approval was based, was flawed.
More recently and most compelling, three researchers (Chensheng Lu, Kenneth M. Warchol and Richard A. Callahan at Harvard’s School of Public Health have just published a study that directly links CCD to neoinsectinoids. Their findings point to wards neurological impairment of the exposed bees and conclusive evidence of CCD where the bees disappeared from the hive. Interestingly, they also had one control hive experience CCD from nosema infection, but the bees died in the hive. They did not disappear.
So these pesticides are no longer used, right? Wrong!
Six months ago, in December 2013, the European Community (EC), placed a temporary ban on three neonicotinoids including the most widespread, imidacloprid, for two years. This temporary ban came hot on the heels of a landmark European-wide, EPILOBEE study commissioned by the EC. While the EC requested that pesticide monitoring be part of the study, various member nations argued that this would “not be feasible”. As Professor David Goulson, a biologist at the University of Sussex, commented: “It does seem odd that the EC spent over €3m on a project on bee health and the words pesticide and insecticide are not used once in the document. Odd indeed!
The EPILOBEE report concluded that the UK is suffering one of the worst rates of CCD in Europe. In spite of this state-of-affairs, the UK was one of eight countries that voted against the pesticide ban. The UK has created a draft National Pollinator Strategy of which one of the “priority actions” is gathering evidence to “determine the effects of neonicotinoids on populations of wild and managed pollinators in field conditions”. So far, so good, but wait…….which independent scientist is leading the study? None. Incredibly, the study will be led and paid for by the pesticide manufacturers, two of whom have been exposed for intense behind-the-scenes lobbying. So much for independent research!
And the US? What action is being taken here? Even less! The Department of Agriculture and the Environmental Protection Agency’s stance is that “The decline in honeybee health is a complex problem caused by a combination of stressors.”
No doubt….but let’s remember three things:
1. Honey bees are the critical catalyst in our food production. We risk losing them through CCD. We risk our entire food chain.
2. The growing body of evidence points to neoinsectinoids as being (at least), one pillar of the causes of CCD.
3. We can actually do something about neoinsectinoids on a global scale. Other elements of the “complex problem” are not easily tackled.
As is often the way on the road to consensus, the evidence is not 100% cast iron, guaranteed, watertight or unanimous, a situation that is easily exploited by intense lobbying by the respective chemical companies.
As a result, commercial interests triumph over the interests of the wider population. Instead of taking rational decisions rooted in Common Sense for the benefit of the entire population, we allow commercial interests to reign supreme.
Churchill is right. Once again, it looks like we will only do the right thing when all other alternatives are exhausted… but by then it may be too late.
Antheraea Polyphemus is one of the larger moths, part of the family Saturniidae or Giant Silk Moths. Common throughout most of the US, Polyphemus lives in a variety of habitats but usually where undergrowth is available for concealment.
Our specimen is at the extreme in terms of size with a wing span just over 51/2 inches. We know it is a male due to its two exquisitely delicate, antennae shaped like ferns. Females have thinner, less showy antennae.
The colorings are also breathtaking. The underside of the wings display a variety of shades of brown, cream and grey, interspersed with ripples of darker and lighter shades in a perfect camouflage for brush. But it is the upper wing surface that are the stars of the show, especially the hind wings. Here, initially hidden from view are two large eyes. Half an inch in diameter, the ‘pupil’ is transparent, ringed with a brown yellow ‘iris’ and surrounded by the black ‘eye shadow’ more typical of owls than moths. And therein lies the rationale for the eyes. An unsuspecting predator such as an American Robin may launch its attack only to be met by the fierce some sight of these two ‘owl eyes’ as the moth extends its wings.
Polyphemus have some other interesting characteristics. They do not eat during their brief lifespan! In fact, they do not even have mouth parts. All their energy is derived from their earlier life form as a caterpillar. Typically, it takes ten days to hatch the egg into a caterpillar and 5-6 weeks to metamorphose into its full size as a moth. Unsurprisingly, given the moth’s inability to eat, the caterpillars eat voraciously.
Finally, Polyphemus are nocturnal so while common in the US, they are not observed as often as butterflies. During the day, they shelter in the undergrowth and are hard to see for all predators.
We were lucky. This one had mated and was at the end of its lifespan. It was barely alive when Danny spotted it and it makes for some beautiful pictures with both a regular camera and under a stereo microscope.
Who hasn’t idled away long summer hours building sand castles on the beach? Most of us have, at some time or other, run those wet buckets of sand back to our castle that rises sometimes lopsidedly, sometimes majestically from the beach. But who ever heard of someone reversing the process and etching castles on a single grain of sand?
Well, artist Vik Muniz and artist/researcher Marcelo Coelho for starters! Muniz is known for creating art that alters perspectives based on context. He creates massive 500 meter long etchings in the earth’s surface. On the ground, they look like trenches. From the air, like drawings in the earth. Now he has reversed the process, creating castles on a single grain of sand.
The process took four years. Muniz would draw a castle and then project it through a special prism. Coehlo, who is also an MIT graduate, would use a Focused Ion Beam to trace each drawing on to each grain of sand. An FIB is more typically used for fixing integrated circuits on microchips. In this instance, Coehlo etched lines a fraction of the width of human hair on to the particle of sand, managing to create crisp images of the castles. That is about 50 nanometers wide or close to the the diffraction limit of visible light, which is why an optical microscope would not work.
Each image requires at least nine scans before it can be printed, following which Muniz turns the concept on its head once again…….by enlarging the final image into four feet,large format photographs.
Muniz picked castles because, “I rely on images that are simple, that you’ve seen a million times… You think you know it but then you have to know it again.” “When someone tells you it’s a grain of sand, there’s a moment where your reality falls apart and you have to reconstruct it. You have to step back and ask what the image is and what it means”, rather like the French when they first looked down from the Eiffel Tower.
“It’s really strange,” said Coelho, “because you’re drawing on to a canvas and you don’t really know what it is and you can’t hold it.”
“I think photography is just re-starting,” said Coelho. “There’s a whole new kind of photography emerging now. A lot of it is happening because of this combination between computers and cameras, and story telling and narratives can emerge as a result.”
I think I’ll stick to the beach, for now.
My daughter left for school this morning like thousands of children across the country – dressed from head to toe in green and after eating a breakfast of green pancakes and green milk. St Patrick’s Day is upon us, but this year the Irish are celebrating with a little more fervor than ever and for good reason. Scientists at the University of Glasgow’s Hunterian Museum have proven beyond doubt that Ireland’s most iconic tourist attraction, The Blarney Stone, famous for giving you the ‘Gift of the Gab’ if you kiss it, is definitively……. Irish!
For centuries, in pubs all over Ireland, debate has raged over the stone’s origins. One camp holds the stone was chiseled from Stonehenge. Another that Robert the Bruce sent it as a gift after his stunning victory at the Battle of Bannockburn in 1314. The debate was ended recently with the discovery of a nineteenth century microscope slide containing a microscopic sliver of the stone so small that it is transparent. Under a microscope, the slide revealed the rock to be a limestone composed of the mineral calcite and containing recrystallized fragments of fossil brachiopod shells and bryozoans…..all of which are unique to Cork where the stone is located.
Dr John Faithfull, curator at the Hunterian museum, said: “This strongly supports views that the stone is made of local carboniferous limestone, about 330m years old, and indicates that it has nothing to do with the Stonehenge bluestones, or the sandstone of the current ‘Stone of Destiny’, now in Edinburgh Castle.”
Alongside the science of the microscope was a touch of the leprechaun. As part of a digitization program, Becky Smith, an intern at the museum, spotted the slide among 40,000 older geological slides contained in handwritten ledgers. . The slide is part of the rock and mineral thin-section collection put together by Professor Matthew Forster Heddle, of St Andrews, one of the giants of 19th-century geology in the UK.
Faithfull said: “It was probably made between 1850 and 1880, during the period when new microscope techniques began to revolutionize our understanding of rocks, and how they form. “He was a pioneer in the use of these techniques to investigate the rocks and minerals of Scotland, and elsewhere. He also seems to have managed to obtain fragments of a number of important historical stones: the collection also includes slides cut from several of the stones at Stonehenge. This was not vandalism – it was bringing the latest scientific tools to bear on the origins of these monuments. We don’t know how Prof Heddle got the Blarney microscope slide, or whether he had it made himself, but he was a major scientific figure, with excellent contacts, and was always keen to acquire interesting samples for scientific investigation. However, in this case, he doesn’t seem to have published anything about the stone.”
There is a long tradition of hanging upside down from the battlements of Blarney Castle, which is the only way to access the stone, in order to kiss it so using a hammer to extract a sample required some dexterity.
Faithfull added: “Very few pieces of the Blarney Stone seem to exist outside Blarney Castle. Apart from our microscope slide, the only other one I’m aware of is in a monument at the University of Texas. However, this object seems to have its origins in a beer-fuelled party, and the genuineness of the fragment must be in doubt.
The Blarney Stone is famous for bestowing the gift of eloquence on those who kiss it. We don’t know if kissing the microscope slide would have the same effect, although I have tried it.”
Honestly….this is not just Blarney….it’s true!
Happy St Patrick’s Day!

At Microscope.com we often say that the technology of light microscopes has not changed much over the past 500 years. Strictly speaking, this is no longer true. Scientists at Hokkaido University in Japan have found a way to use ordinary light to detect objects smaller than the limit of traditional light microscopes. Up until now, light microscopes have been limited by the Rayleigh diffraction limit, which states that light cannot be used to resolve a structure smaller than its own wavelength. Since the shortest wavelength of visible light is a few hundred nanometers, scientists have turned to X-Rays and electron microscopes in order to resolve smaller elements.
However, for some time scientists have suspected that a weird effect of quantum mechanics known as entanglement might overcome the Rayleigh limit and the Hokkaido team have done just that. Einstein referred to Entanglement as “spooky action at a distance”. It involves two photons in opposite polarization states that become entangled so that even when separated by infinitely large distances (think light years), changes to one are reflected in the other. Using such entangled photons, the microscope visualizes much smaller structures than could be achieved with ordinary light.
In this case, the scientists generated entangled photons by converting a laser beam into pairs of photons that were in opposite polarization states at the same time (superposed particles). The physicists used special nonlinear crystals to achieve this superposition and then focused the entangled photons on two adjacent spots on a flat glass plate with a Q-shaped pattern made in relief on the plate’s surface. This pattern is only 17 nanometers higher than the rest of the plate and almost impossible to see with a standard optical microscope. However using the entangled pairs, the lettering was completely visible and 1.35 times sharper (signal-to-noise ratio) than the standard quantum limit.
Inevitably, obtaining an image was not as simple as using an eyepiece. In this case, the team generated the image electronically by measuring the difference in optical path length between the two beams, a difference that is caused by the marginally thicker glass where the letter rises up from the surrounding surface. The scientists could not measure this directly, so they used the interference pattern of both beams as they passed through the glass. Since each of the entangled protons provides information about the other, the process is more efficient and results in a sharper image.
The major drawback to the process is that it took almost a full day for the microscope to generate actual images so a key improvement for commercial development is the ability to speed image development. However, the team has proven that the refractive index of light microscopes can be enhanced which could have a major beneficial impact on Life Sciences and other disciplines such as cryptography. Currently, in order to observe transparent organisms in such detail, X-Rays or electron microscopes are required. Both are expensive while X-Rays cause damage to living cells. Since this entangled photons approach uses simple lasers with infrared rays, it offers both an inexpensive and harmless solution to future generations.
My last blog encouraged kids to look at a snow crystal under a microscope, something you can do more easily than you might realize. But this Vimeo video takes it to a whole new level. Filmed through a microscope by Russian filmmaker Vyachelsav Ivanov, it shows the simple beauty of snow crystals as they grow. You can clearly see the geometry in the exquisite time-lapse photography which combined with appropriately simple musical accompaniment provides a winter pleasure for all ages.
Most of our OptixCam digital microscope cameras include the ability to employ time-lapse photography and while you may require some practice before matching this video, it is a fun and useful feature that is easier to use than you might think.
Let it snow!
For much of the Northeast US, the winter snow has arrived with a vengeance. Schools are closed. Kids are thrilled, but stir crazy and parents are praying for relief. There is only so much sledding you can do and who plays in snow without getting cold and wet? So why not take a closer look?
Snowflakes are not only magical in drifts, but also as individual crystals. With a little bit of patience and a low power microscope, you can successfully engage your kids in a worthwhile activity that will produce some spectacular images. Snowflakes start as water vapor that is supercooled below freezing. It is not frozen rain, which we know as sleet. Rather the water vapor freezes round a particle of dust and grows from there as additional water vapor attaches. The resulting crystals have an extraordinary range of shapes and sizes largely depending on the temperature and humidity outside. In addition, time and the distance additional water vapor has to travel to reach the crystal affects the level of complexity of an individual snowflake.
These four variables: temperature, humidity time and distance are responsible for the fact that every snow crystal is unique although the full science behind it is still a mystery. Interestingly though, snow crystals do fall into approximately 35 different categories that range from the most common, simple hexagonal prism to some extremely complex shapes. The dryer the air (low humidity), typically the simpler the shape. As they grow through a process known as branching, they become more complex
Now, it’s time to try your hand at viewing or photographing a snowflake and an individual snow crystal. You will need a low power microscope (with or without a microscope camera) or a handheld digital microscope. Leave it in the garage so it gets suitably cold although ensure that it is not exposed to any condensation. Similarly, leave a glass slide, small artist’s paint brush and a 3×1” piece of dark-colored, construction paper in the garage or outside where they are protected from the elements. In other words, you want them cold!
Now wrap up warm. First, look at an entire snowflake. Hold the construction paper out in the snow or carefully place a sample of snow on to the paper. Make sure that you keep the underside of the paper dry as you do not want to get your microscope wet. Now quickly place the paper under the microscope and focus it. View it at different magnifications and note the level of detail that you see.
Now take the paint brush and carefully, lift a single flake on to the glass slide Place it quickly, but carefully under the microscope and focus in on the individual crystal. Take a quick picture and try to note its shape and branching characteristics.
You can achieve good results with any low power microscope or digital microscope. You should also try different lighting. For example, use a different color filter for more definition or try a back light. For more sophisticated use, we recommend an OCS digital system that includes a microscope camera with a monocular zoom lens.
In any event, it is a rewarding project that will keep your kids happy outside – and that’s the main thing!
The revolution in digital technology has touched the microscope world in some truly amazing ways. With a few mouse clicks you can now get a state-of-the-art digital microscope capable of 400X magnification that fits in the palm of your hand. Did I mention they are easy enough for a child to use? Simply hold the microscope over the object, focus the image using the thumbwheel and capture detailed images or video at the touch of a finger.
Yet this tremendous capability is not without a few shortcomings. The compact design means that the image sensors and focusing lenses have a big job to do and a very small space in which to do it. In many situations this can lead to compromises in lens quality, depth of field issues, and limited magnification range, resulting in blurry edges, hazy colors and less-than-optimum images.
Fortunately, these issues and many more have been addressed by Dino-Lite in their new lineup of Edge series handheld digital microscopes, all of which feature brand new 1.3MP CMOS sensors, full range magnification from 10X to 220X, wider field of view and enhanced LED illumination.
The AM4515ZTW will automatically display the magnification level on screen, making it easy to dial up or return to a specific magnification level again and again. This is especially helpful to quality assurance inspectors who need to make frequent comparisons at a known level of magnification for their certification workflow.
The AM4815ZT has two distinct image capture modes which are unique and proving quite popular. They are Extended Depth of Field (EDOF) and Extended Dynamic Range (EDR). EDOF mode works by automatically capturing several images in sequence, each of which is at a slightly different focus depth. The software will then digitally “stack” or compile the images into one frame, resulting in a single sharp image with vertical surfaces (Z-axis) in clear focus. This makes it perfect for inspecting bolts, drill bits, bore holes and anything with a degree of height or depth.
The EDR capture mode uses the same mulit-image concept, yet with highly reflective surfaces. It functions by automatically taking many images at slightly different exposure settings and then digitally “stacking” or integrating them into a single image. In this fashion, the EDR mode can reveal areas of pitting, corrosion and other details of dark or reflective areas which may be lost in normal imaging.
This type of imaging fidelity works well for pcb quality inspection, certified gemstone identification and grading, electronics repair, and any situation calling for a big image of a very small part.
Pretty incredible stuff when you consider that this imaging capability has only been around for a handful of years at the most, and it bears strong testimony to the warp speed of technological development we currently live in. One can only wonder where we’ll be in a year, or even 6 months from now.
Most people know that a monkey was the first mammal into Space, but I only just learned that 800 ants are at this very minute guests on the International Space Station (ISS). The idea is to observe how the the ants adapt their foraging behavior in microgravity conditions with a view to developing more intelligent robots. While this may not seem an obvious source of robotic inspiration, ants engage in collective behavior, or ‘distributed algorithms’ in robotics, to achieve a variety of objectives including foraging.
Professor Deborah M. Gordon, of Stanford University who leads the experiment created a series of eight rectangular habitats with dividers between each area. Each area had about 100 ants (Tetramorium caespitum) inside. When the dividers were in place, the ants were limited to their initial area with a correspondingly high density of ants. In this high density environment each ant foraged within a small area in what appeared to be a circular and random pattern. When the dividers were removed, the ants experienced a lower density environment and walked in straighter lines.
Apart from helping robotic technology, the experiment is being monitored by thousands of students across the US. These students are participating in live science while hopefully, gaining inspiration to work in space science, not to mention having fun at the same time. I for one never had a science project live from the ISS!
Professor Gordon pointed out that all animals have to adjust to microgravity environments, be it human, ape or insect. For example, the way nutrients circulate around cells differently or the way genes are expressed. By the same token, all animals need to re-adapt to Earth’s gravity on return. An amusing example comes from a Johnson Jumper spider that was a guest on the ISS in 2012. While the spider did adapt to microgravity, it also needed to re-adapt to earth on its return. For a short time, it kept jumping….and landing on its back.
But this experiment extends beyond the rarified atmosphere of Outer Space. It can involve you. Professor Gordon hopes that students round the world will record the collective action of their local ants when foraging. All you need is to build a couple of interconnected habitats with dividers so that you can experiment with both high and low density populations. Ants also are fascinating to examine under a microscope…..but that’s for a later blog. Meanwhile, enjoy the video of these brave “antronauts”!
As you can imagine, at this time of year, we receive a lot of calls from parents and grandparents asking which microscope they should buy for their young (grand) child. While we have an article on this question it is worth summarizing for Holiday convenience!
We have three recommendations, bearing in mind that our most important criteria is to engage the kids.
OUR NO 1 CHOICE
Most parents arrive at our store with an image in their minds of a classic compound (high power) microscope. They believe their child to be very bright and they are hoping to stimulate an interest in science. Unfortunately, this often means pushing the child towards a high power microscope, but increasingly we lean towards starting with a handheld digital microscope such as the Explorer Series as a better and more engaging type of microscope. Most kids love all things digital and the Explorer Series provide a high COOL quotient. They are easy-to-use, offer instant live video and still images in addition to a good value/quality equation. They are plain fun to use, yet are used in industrial inspection throughout the world.
CLASSIC COMPOUND MICROSCOPE
By the same token, the classic compound microscope may, at worst, be inappropriate and, at best, less than engaging. The reason is that a high power microscope involves specimens that are quite abstract in nature. Young children, however bright, typically do not have the level of cognitive development to be engaged by such abstract images as cells on microscope slides. After all, without stains, many specimens are rather dull and colorless!
That said, the fun of a compound microscope lies in the slide preparation. Choosing which specimen can be a thoroughly inclusive, cross-generational activity that is great fun for the child, parent and grandparent. Taking the cheek swab or preparing the onion skin requires significantly more time in preparation than actually viewing it. Typically, we recommend a compound microscope for kids with an established interest in microscopy and/or science, for kids over 12 years old or where budget is highly limited since there are a several good value such microscopes for kids.
THE STEREO MICROSCOPE OPTION
The alternative for younger kids is a stereo or low power microscope. These microscopes are used to view macro specimens that are visible to the naked eye: insects, crystals, pond cum etc. The advantage is that the kids can immediately relate to the specimen since they can see it. A bee, for example, is instantly recognizable. In addition, it is instanttly ready fr viewing. Simply place it on the stage of the microscope. The only drawback is that young kids may not be big enough to use the binocular eyepieces since the distance between their eyes maybe less than the distance between the eyepieces(interpupillary distance), even at the lowest setting. However, they can use one ocular until big enough to graduate to both eyepieces.
Of course, ultimately, much depends on the level of child’s interest, your budget and specific application, but if in any doubt, give us a call for further advice, Toll Free: 877-409-3556.
To our great delight, our new Microscope.com website design has won a coveted Outstanding Achievement Award from the Interactive Media Awards (IMA). The award is for excellence in the design, development and implementation of the new design skin, which was executed by Intedyne. The principal, Dmitriy Yermolayev is unquestionably one of the finest back-end coders in the US and he was ably assisted by Nasa Ikeda’s refreshingly elegant and effective front-end design.
The honor, granted by the IMA, recognizes that the project met and surpassed the standards of excellence that comprise the web’s most professional work. The judging consisted of various criteria, including design, usability, innovation in technical features, standards compliance and content. In order to win this award level, the site had to meet strict guidelines in each area – an achievement only a fraction of sites in the IMA competition earn each year.
To comprehend the extent of our pleasure, you have to consider that we have spent the best part of three years redesigning the website. Two initial aborted attempts involved so much time, expense and stress that we have some sympathy with the current healthcare website debacle! It is hard, more than hard, to convert to a new system with sophisticated requirements and it is primarily due to Dmitriy’s intellect, experience and steady personality that has enabled us to persevere through through the fog of dismay to this final, successful iteration.
Most important, while we love the look and feel of the site, it is easy to navigate and perfomring above expectations. Kudos to Dmitriy and Nasa.

This morning, I had a craving for pâté on toast. Weird maybe, but not as weird as what I found on the pâté, which has been sitting in the refrigerator too long. Mold! I though it would be fun to see what it looks like under one of our new Explorer handheld digital microscopes and before I knew it, I was seeing strange faces in the images.
These images were taken using an Explorer Pro 1 which includes 1.3MP resolution and 10x-50x, 200x variable magnification. It took all of a few seconds to set up and I have been dodging ‘real work’ while I played with it. But it is the day before Thanksgiving, after all!
That’s what I like about these Explorer microscopes. They are easy and fun to use while you can explore all sorts of items around your house and garden.
Have a Happy Thanksgiving and may your turkey be absent any sign of mold.
