In that sensational book, the Italian naturalist provided the first detailed account of organic tissue – enabled by studying organic matter under the lens of newly invented microscopes. Now, the latest optical microscope technology is capable of imaging viruses that live in organisms. Conventional Light Microscopes: Widefield and Confocal Conventional light microscopes – widefield and confocal optical microscopes – can accurately depict image samples at resolutions of ar...

New type of placental structure discovered in animals The Cyclostomata is an ancient group of aquatic colonial suspension-feeders from the phylum Bryozoa. The fact that they have unique placentae has been discovered by researchers at St Petersburg University and the University of Vienna. The coenocytes, i.e. large multinucleate cell structures, originate via nuclear multiplication and cytoplasmic growth among the cells surrounding the early embryo. Interestingly, the coenocytes are commonly found among fungi and plants, yet are quite rare in animals. It is the first time coenocytes have been ...

Biodegradable Nanoprobes Improve Cancer Diagnosis Written by AZoNanoMar 12 2021 New nanoprobes, which were recently developed by Imperial College London (ICL) and tested in zebrafish, could help identify cancer more precisely and may support the diagnosis and treatment in the days to come. Purple cancer cells are labeled using bioharmonophores (white label). Image Credit: Imperial College London. To clearly visualize tumors in the body for cancer diagnosis, physicians can utilize miniature optical probes (nanoprobes) that illuminate upon binding to tumors. Such nanoprobes enable doctors to de...

Reclaiming what it means to be a scientist through photography and storytelling

 E-Mail To highlight tumours in the body for cancer diagnosis, doctors can use tiny optical probes (nanoprobes) that light up when they attach to tumours. These nanoprobes allow doctors to detect the location, shape and size of cancers in the body. Most nanoprobes are fluorescent; they absorb light of a specific colour, like blue and then emit back light of a different colour, like green. However, as tissues of the human body can emit light as well, distinguishing the nanoprobe light from the background light can be tough and could lead to the wrong interpretation. Now, researchers at Imperi...
