Types of Microscopes
Microscope is one important tool that is functional to see objects or organisms that are so small. Along with the progress of science and technology, types of microscopes and zoom capabilities experience the advance.
There are two types of microscopes; light microscope and electron microscope. Light microscope include bright field microscope, dark field one, phase contrast one and florescent one. Microscope that is often used in secondary schools for the practicum is bright field microscope.
Bright field microscope is a microscope with a field (field of view) that surrounds the specimen appears bright, while the specimen looks darker. This is because light from the source (mirror or lamp) passes through a lens system to the top without experiencing a change, thus it forms the bright field.
Microscopes in common use today use two or more lenses (lens system) such as ocular and objective lenses to enlarge the object. The types of this computer range widely, from a simple one for the purposes of secondary school up to a fairly sophisticated one for research purposes.
The main characteristic of the microscope today among others is monocular with the upright and tilted tube, binocular, trinocular, the power of the lens that is used, the light source (using a lamp that is attached), and even the camera that can be mounted (video camera) on trinocular microscope and can be connected to your TV.
Meanwhile, electron microscope has the highest magnification. It can amplify a tiny thing up to 500.000 times. It uses electron in the place of light in light microscope.

Did You Choose The Proper Puggle Breeders?
Are you planning on buying a puggle to your home? They can be quite a handful for the owner if purchased. Even if you fall in love with the puggle the moment you set your eyes on it, it is better to find out some information about the puggle as well as the puggle breeders.
There are so many puggle breeders who are in the business just for the money it brings. Puppy mills and dog farms are places where pets are treated in an unhealthy way. Knowing where your pet came from is very important. Some people may think that it does not matter from where the pet came from as long as it will be treated well in the new owners’ home. Unfortunately this is not the truth. A dog’s first few years are crucial for its development.
Puggle breeders who carry out dog farms and puppy mills treat their puppies in a different way from puggle breeders who do it at home. Most puppies that are born and brought up in dog farms live in cages and stay away from human companionship for quite a long time. Love and kindness are feelings not familiar with them. Since these puggle breeders breed their pets in farms, etc, the puggle’s lack emotional communication with humans. In addition to all these, they are likely to end up with different behavioral problems.
A lot of puggle breeders in dog farms do their job as a business, to earn a good profit. The profit is gained at the expense of innocent dogs. If you have no idea about this type of puggle breeders but decide to purchase a dog from such a place, you’d only be contributing to their suffering. This suffering is not only for the pet you decide to buy, but also for their mother. Puggle breeders are happy when puggles from their dog farm or mill are sold. So when the sales rise, it gives way for more breeding. Luckily not everyone is the same. There are enough of puggle breeders who are more responsible and are not solely relying on a profit. Such puggle breeders have the intention of bringing in a new member to a family; in this case it will be a new puggle. Buying a puggle from responsible puggle breeders will ensure the healthiness of the dog as well as help them in identifying its lineage.

Why should stained specimes be viewed only under brightfield?
I understand the purpose of phase contrast and staining, but what would happen if you viewed a stained specimen through a standard microscope under phase contrast?
The answer to your question depends on the amount of light returning from the stained sample into your eye. If you are looking using a standard microscope, then you are only receiving the light reflected back, which may not be very much, as the stain or the sample could absorb light.
However, if the light source is behind the sample, as in brightfield, then you are transmitting light through the sample, and are not dependent on reflection to view the image. Therefore, your optical efficiency will be much larger, since you are avoiding reflective losses.
Nanoscale Car Built with Four-Wheel Drive (Scientific American)
Small cars are in vogue, thanks to rising fuel costs and environmental
concerns. But the Fiats and Smart Cars of the world have nothing on the new
four-wheeler developed by European researchers. Netherlands-based researchers
Tibor Kudernac of Twente University and Nopporn Ruangsupapichat of the
University of Groningen and their colleagues have engineered a single molecule
