Australian scientists have developed the world's smallest hand-held microscope, which is capable of detecting cancer cells often missed by surgeons during operations to remove breast cancer tumours.

Music has magical powers—if you don’t believe me, just ask this kid—and the way a relatively low-tech device like a record player creates it can be equally mystifying. Using a scanning electron ...

A method for turning a small, $40 needle into a 3-D microscope capable of taking images up to 70 times smaller than the width of a human hair has been developed by scientists. the microscope technique ...

According to the researchers, visualizing this at the molecular level helps further our understanding of host-pathogen interactions and contributes to the development of novel therapies for the ...

Western Australian researchers fighting breast cancer have won the final of an international technology competition sponsored by SPIE, the owner of optics.org. Associate Professor Robert McLaughlin, ...

Beginning with a US$40 needle, researchers from the University of Utah have designed a microscope with the ability to generate miniaturized 3D images. The low-cost device is capable of producing ...

Medical needles have many uses. Since the needles are directly inserted into a person’s body, it is critical that manufacturers adhere to national and international standards for shape, materials, and ...

Microscopes make tiny objects visible, as their name suggests. However, modern microscopes often do this in a round-about way, not by optically imaging the object with light, but by probing the ...
