Electron Microscopy – News and Features

Researchers have discovered that nanoscale silver (Ag) can autonomously self-heal structural damages like nanocracks and nanopores at room temperature and frigid temperatures as low as 173 K.

Researchers identified the nucleolar protein PQBP3 as key in linking aging to neurodegenerative diseases. The study shows PQBP3's relocation during cellular senescence disrupts nuclear membrane stability.

Researchers have detailed a bacterial defense mechanism involving two proteins, DdmD and DdmE, that target and degrade plasmids. This system, which uses stable guide DNA, shows promise as a novel genome-editing tool.

Scientists have discovered a virus that caused a nationwide die-off of superworms and have pioneered a different way to search for and identify emerging viruses and pathogens in humans, plants and animals.

Harvard-led researchers revealed how herpes simplex virus (HSV) develops resistance to antiviral drugs through changes in protein dynamics, not just mutations at drug-binding sites.

Research suggests chlamydia bacteria may persist in the intestines after antibiotic treatment, potentially causing recurrent infections. Using intestinal organoids, researchers found chlamydia could enter the gut from the bloodstream

Researchers discovered that lithium ions remain immobile in the cathode of fully charged lithium iron phosphate batteries, limiting storage capacity by up to 25%. Using advanced microscopy, they mapped ion distribution and crystal lattice distortions.

University of Arizona scientists have developed the world’s fastest electron microscope, capable of capturing electron motion in attoseconds. This "attomicroscopy" technique allows researchers to observe previously unseeable rapid processes.

Researchers have illuminated the role of chaperone proteins in protein folding in unprecedented detail using cryo-electron tomography.

A view into how nanoscale building blocks can rearrange into different organized structures on command is now possible.
