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.

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 ...

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 ...

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 ...

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 ...

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 ...

Martin Jones describes how new approaches to electron microscopy are helping biomedical scientists get the most out of ever-increasing flows of data Thinly sliced This focused ion beam scanning ...

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 ...

Scanning electron microscope images of trona found in samples of the asteroid Bennu returned by NASA’s OSIRIS-REx mission. Trona is water-bearing sodium carbonate, also known commonly as soda ash.
