Cool operator: the Saharan silver ant Cataglyphis bombycina. (Courtesy: P Landmann) A species of desert-dwelling ant is able to tolerate temperatures exceeding 50 °C because its body hairs act like ...
The DeltaVision OMX V4 enables Total Internal Reflection Fluorescence Microscopy (TIRF). This technique uses an evanescent wave to selectively excite fluorophores that are close to the coverslip. This ...
The body hairs of the Saharan silver ant cause total internal reflection of light to make the ants almost ten times more reflective, preventing overheating and yielding their silver sheen, according ...
Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. from a ...
Light that is reflected back from the edge of the medium it is traveling through. When light rays travel at an angle greater than the "critical" angle, which is determined by the medium, the light ...
Total internal reflection microscopy is a light microscopy technique that relies on total internal reflection of illumination light to generate an evanescent wave that extends less than 200 nm from ...
Life in the scorching hot Sahara Desert is no problem for an ant that has evolved an effective and stylish heat-repellent system, new research finds. Hairs on Saharan silver ant act like prism to ...
When a ray of light that is travelling through a piece of glass strikes the interface between the glass and the air, it changes direction according to Snell’s law. If the angle of incidence is less ...
