Tissue samples scatter light and shut out a deeper gaze. Tissue-clearing agents have changed that, but scientists must consider optimizing the optics when using these methods. To study the causes of ...

A project at the University of Zurich has designed an objective for light microscopy based on the reflective principles used in Schmidt telescopes and also found in nature in the eyes of scallops. The ...

Neuroscientists have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one hand ...

A recent program of the Department of Education expanding the work immersion hours for Senior High School (SHS) students seems concerning. Accordingly, the proposal currently being piloted in 14 ...

Over on YouTube [Applied Science] shows us how to make an f/0.38 camera lens using an oil immersion microscope objective. The f-number of a lens indicates how well it will perform in low-light. To ...

Some species of mussels can see. Scallops, for example, have up to 200 eyes that help them detect predators such as an approaching starfish. However, the eyes of scallops differ significantly from the ...
