For the first time in plants, we used APEX-based electron microscopy to map the precise localization of ATG8 at the vacuolar membrane after stress! 🚀

Pushing the boundaries of plant cell biology—one EM image at a time. ⚡👀

Images and instruction span from the area level down to the subcellular. Check out this rabbit motor neuron! Again, the text walks students through what they should be learning and appreciating from the image.
3/n
An electron microscopy image of a motor nerve cell (ventral horn of rabbit spinal cord; multipolar). It shows a cell body with a large nucleus. An axo-somatic synapse on that cell body is labeled, as are 2 dendrites. Surrounding the nerve cell are other, labeled features: glial cell nuclei, capillaries. Screenshot of text: 49 Motor nerve cell - Ventral Horn of Rabbit Spinal Cord, Multipolar Motor Neuron Cell Body View Virtual EM Slide Motor Neuron Cell Body. In this electron micrograph, note some of the features you saw in ventral horn motor neurons with the light microscope, such as the large, pale nucleus, prominent nucleolus, Nissl bodies, dendrites and axon. Adjacent to the neuron, note myelinated axons of various sizes and also that there are no spaces between cell processes. All spaces are occupied either by the processes of neurons or glia or by capillaries (these capillaries are somewhat swollen here because the tissue was fixed by perfusion).

Tanmay now also combining electronmicroscopy with metabolic imaging, see their preprint with @kiranrpatil.bsky.social @lisamaierlab.bsky.social and colleagues

Extensive PFAS accumulation by human gut bacteria
Per- and polyfluoroalkyl Substances (PFAS) – the so-called ‘forever chemicals’ – are a major cause of environmental and health concern due to their toxicity and long-term persistence[1][1],[2][2]. Yet...
