Spider mite, SEM

Spider mite. Coloured scanning electron micrograph (SEM) of a spider mite (Tetranychus sp.). It is an economic pest and plant parasite, found on vegetable crops, fruit trees and flowers. It feeds on the leaf sap, which causes leaves to mottle, turn yellow and fall off. The spider mite is named due to its ability to spin a web, which it does across a leaf surface that secures and protects it against predators. Their numbers can be controlled with organophosphorus pesticide, although some resistance has developed. Another method is biological control, using a natural predator, such as gall midge larva (Feltiella acarisuga). Magnification: x135 at 6x7cm size

Artwork of asthmatic respiratory system on inhaler

Asthma. Artwork of part of the respiratory system, seen on an aerosol inhaler (blue), showing the effects of asthma. The bronchi, covered in bands of cartilage (pink), lead to smaller bronchiole airways that end in clusters of alveoli air sacs. One of the clusters is seen in section, revealing the sputum, or phlegm (yellow), it contains. In asthma, a trigger, such as an allergen, causes the bronchioles to narrow and become inflamed. This results in increased production of mucus, further reducing the lungs oxygen capacity. Asthma is treated by taking a bronchodilator drug to widen the bronchioles using an aerosol inhaler
