Our eFIB-SEM (as per Xu et al. 2017 https://elifesciences.org/articles/25916 ) runs 24/7 for up to 8 weeks, when it runs out of source. And it's essential that it does so, uninterrupted, since it's imaging at nanometre resolution, milling 2 nm slices at a time with an ion beam and then repeatedly imaging the block face. The process is unsurprisingly very sensitive; was hard enough to overcome the reheat cycle of the instrument itself (every 60 hours or so) by detecting it, de-engaging the beams and then seamlessly re-engaging with the block face.

A brief video of the kind of data we acquire:

The MS Windows computer deciding to reboot on its own is unacceptable.

Atomic Insights into Antiferromagnets: A New Imaging Frontier

Scientists used a new imaging method to see atomic-scale magnetic structures in antiferromagnets, important for future fast electronic devices.

#Antiferromagnetism, #Spintronics, #MaterialsScience, #ElectronMicroscopy, #Nanotechnology

https://newsletter.tf/new-imaging-technique-shows-atomic-spin-structures/

A new imaging technique can now see the tiny magnetic structures inside antiferromagnets, which is much better than before. This could help make electronics faster.

Postdoc position: Career Returner Fellowship

"The LMB is proud to launch a three-year fully funded fellowship for scientists who have had a career break of 12 months or more."

"At the LMB, we understand that stepping away from research – even briefly – can affect career progression. That is why we have created a dedicated postdoctoral fellowship to support researchers who have taken a career break of 12 months or more, for any reason, for example parental leave, health reasons, caregiving, a career change or other personal circumstances."

https://mrclmb.ac.uk/careers-and-people/postdocs/career-returner-fellowship/

Happy to discuss applications to our lab in #Drosophila #connectomics, #ElectronMicroscopy or #ComputerVision applied to #BioimageInformatics.

Remembering George Palade, born #OTD in 1912. His use of cell fractionation and electron microscopy led to many discoveries and laid a foundation for modern cell biology. I was fortunate to know him late in his career and early in mine. He exemplified everything academic leadership should be. #cellBiology #ElectronMicroscopy

New preprint from Benoit Zuber's group showing that FerriTagging (a method for sticking a ferritin particle on a protein of interest so that you can see it) is compatible with cryo-electron tomography.

This is very neat. CoI: my lab developed FerriTag a few years back. Great to see it in action!
