By allowing just the right amount of light to reach the retina, the pupil helps you see clearly and lessens glare both during the day and at night. The pupil is a part of the eye that's extremely important for vision. The pupil is surrounded by muscles that make it smaller (constrict) in bright light and make it larger (dilate) in dim light. The pupil is an opening in the center of the iris that changes in size to allow more or less light into the eye. This guide to polycoria explains the difference between true and false polycoria, how polycoria may affect vision and how the condition can be treated. In cases of true polycoria, each pupil reacts to light and functions independently of the other one. Polycoria is an extremely rare eye disease in which a patient has multiple pupils in one eye.

These are oval-shaped spores on the end of the stem-like conidiophores. For example, they have olive-brown conidia (asexually produced spores). The asexual structures (conidiophores) that the fungus forms are similar to those of Penicillium roqueforti, but have a different specific shape. This means that the fungus can have offspring sexually, with half the genes of another, or asexually, with only its own genes. R emersonii can reproduce sexually as well as asexually. Thus, the fungus may help improve biofuel production. However, a recent study found that R emersonii produces two specific enzymes that can completely break down the remnants of xylane. Currently, plant material cannot be fully utilized because xylane, a substance commonly found in plants, cannot yet be broken down properly. Generally, several pretreatments are needed so that enzymes can break down the plant material. ![]() Among others, grass-like plants can be used to make biofuels, but this process requires the breakdown of plant substances such as xylan (a collective name for specific sugars). These are renewable fuels that can be an alternative to fossil fuels. Rasamsonia emersonii might also be useful in producing biofuel. This organism might be able to produce heat resistant material in the future. Furthermore, we are looking to see if the genes of this fungus, which cause it to resist heat so well, can be put into another organism. R emersonii is also currently being studied to see if it can produce other useful substances for us. Humans can use chitinase to fight fungal infections. R emersonii uses this to minimize competition from other fungi in its environment. This is a substance that breaks down chitin, thus killing other fungi, because fungi have chitin in their cell wall and die when it breaks down. One of the substances made by R emersonii is chitinase. This makes Rasamsonia emersonii an extra useful fungus for humans. People can make good use of this property: by heating the mold, these heat-resistant substances can be easily extracted from the mold because everything else breaks down. As a result, the fungus is very good at making substances that can withstand higher temperatures. Rasamsonia emersonii is a thermophilic fungus: the fungus only grows in warm environments of at least 45 degrees Celsius. ![]()
