A new microscopy method enables researchers to visualize the activity of the enzymes caspase-3 and alkaline phosphatase in various biological samples (Nat. Methods 2024, DOI: ...

One variation of electron microscopy is transmission electron microscopy (TEM). In a TEM experiment, the electron beam passes through the sample and the electrons are directly imaged onto an electron ...

Living organisms are complex systems with scales of organization spanning the range from Angstroms to meters. Even when consideration is limited to single cells and smaller, there is still a range of ...

To unravel the complexities of biological phenomena, scientists have long relied on microscopy to visualize the intricate details of their specimens, including tissue architecture, cell morphology, ...

Researchers have adapted a class of techniques employed in astronomy to unblur images of far-away galaxies for use in the life sciences, providing biologists with a faster and cheaper way to get ...

Advanced light microscopy techniques are giving scientists a new understanding of human biology and what goes wrong in diseases Katarina Zimmer, Knowable Magazine Innovative techniques are helping ...

Chemotherapy is a powerful weapon against cancer, but certain cells resist treatment by entering a dormant stage called senescence. These therapy-induced senescent (TIS) cells may become resistant to ...

For the first time, researchers have observed live and in high resolution how influenza (“flu”) viruses infect living cells. This was possible thanks to a new microscopy technique, developed at ETH ...

Confocal microscopy is a specialized fluorescence imaging technique that scientists use to acquire images at greater resolution than conventional microscopy. 1 In addition to scanning the lateral x ...

How flu viruses enter cells has been directly observed thanks to a new microscopy technique with the potential to revolutionize research on membrane biology, virus–host interactions and drug discovery ...
