The walleye is a cool-water freshwater fish that is popular food and sport fishing target with anglers throughout their range. Walleye are known for their olive/gold coloration with five darker patches that extend to the upper portion of the fish. Their name comes from their eyes, which are capable of reflecting white light. This gives the fish impressive eyesight and allows the fish to see in dark or murky conditions. Their impressive eyesight makes them a tough and respected angling target, even though the average walleye is not renowned for their fighting qualities. They are mostly caught in low light conditions or when there is considerable chop on the water. The maximum size recorded is 107 cm (42 in) and 11.3 kg (25 lb), but the average fish caught by anglers is around 30-50 cm (12 – 20 in). Let’s find out where these fish live.
Scabies is a contagious skin disease caused by the mite known as Sarcoptes scabiei. This mite is very small and is usually only visible with a microscope. It is a human parasite (and also infects some other animals) and buries under the skin where it causes an allergic response. The most common symptoms are an intense itching and rash caused by the burrowing mite. In rare cases, such as in those with a compromised immune system, the mite is able to breed rapidly and this causes a scaly rash with thick crusts of skin. The disease is usually transmitted to others via skin-to-skin contact and symptoms do not usually occur until four to six weeks. There are about 300 million cases of scabies in the world each year. Let’s find out how this disease is treated.
Nitrogen is a colorless and odorless gas at room temperature and a chemical element represented by the symbol N and atomic number 7. It makes up the largest volume of the air (about 78.1%) on Earth and is an essential building block of amino acids and nucleic acids (DNA and RNA). This means that nitrogen is essential to life! There are two stable isotopes of nitrogen and both are found naturally on Earth. However, there are a number of other isotopes of nitrogen that have been discovered. Let’s find out how many isotopes nitrogen have been identified.

An X-ray machine, usually referred to as an X-ray generator, is a device used to take images of the inside of an object. They are best known for their use in the medical field where they can help medical professionals see inside the body to make a diagnosis (such as looking for a broken bone or tumor). However, they are also important for tool used in security such as with x-ray luggage scanners at airports. Basically, X-ray machines work by passing a beam of X-rays (a type of electromagnetic radiation) through an object. Some of these beams pass through and some are absorbed. The differing pattern of radiation is detected by a special detector screen or device to produce the final image. The X-ray machine was one of the most important medical advancements of all time. Let’s find out who invented this device.
Snakes are long, thin, carnivorous reptiles that are best known for being legless animals. They are often considered to be dangerous to humans as some species are capable of injecting venom that can kill a full grown adult in minutes. However, many species of snakes are nonvenomous and are completely harmless to humans. Snakes are found throughout most of the world, although they are not found in Antarctica and on some small land masses. They can live in a variety of habitats and are also found in the ocean. Most snakes are usually about 1 m (3 ft) in length, although some are much larger and smaller than this. Let’s find out which species of snake is the smallest in the world.
