You may have heard of the silk moth that can detect a female's presence from miles away. This is possible because the moth, like most animals, has the ability to detect pheromones, which are chemicals produced by other animals.

Pheromones are essentially chemical messengers released by animals that affect other animals. Usually they serve to communicate something about territory, reproduction and caring of offspring, the presence of danger, or even the presence of a rival.

Hyaluronic acid, a key component of human tissue, aiding the body's flexibility, mobility and moisture retention is a popular component of many anti-aging products but can also provide a wealth of benefits in the medical sphere. Recently, in an attempt to find effective treatment methods for arthritis, scientists have found a strong association between levels of Hyaluronic acid and severe knee and hip arthritis known as osteoarthritis or OA.

Recent research into the purification of Hyaluronic acid (HA) from the vitreous humor of fish has shown great promise. This method is highly efficient and easier than derivation from rooster combs and other traditional sources of HA.

The first microscope was created hundreds of years ago. In the passing centuries, microscopes evolved into powerful, precise tools that allow scientists to view tiny objects at a level of detail that seems unreal.
