Seeing viruses by both light and electron microscopy

Advances in both light and electron microscopy are improving scientists' ability to visualize viruses such as HIV, respiratory syncytial virus (RSV), measles, influenza, and Zika in their native states. Researchers from Emory ...

Microscopic chariots deliver molecules within our cells

On the cellular highway, motor proteins called dyneins rule the road. Dyneins "walk" along structures called microtubules to deliver cellular cargo, such as signaling molecules and organelles, to different parts of a cell. ...

Scientists illuminate structures vital to virus replication

In the fight against the viruses that invade everyday life, seeing and understanding the battleground is essential. Scientists at the Morgridge Institute for Research have, for the first time, imaged molecular structures ...

Actin cytonauts at play in the cell

(Phys.org) —Actin "comets" are scaffolds of polymer that various bacteria and viruses construct within cells. Party-crashers, like Listeria or Shigella bacteria, are able to seed structures using special patches of their ...

Method speeds up time to analyze complex microscopic images

Cryo-electron tomography permits researchers to study in detail the microscopic structures inside of cells. Researchers who typically required a week of effort to dissect the 3-D structure of a single cell will now be able ...

Research team captures images of pathogens' tiny 'syringes'

Salmonella and many other bacterial pathogens use a nano syringe-like device to deliver toxic proteins into target human cells. Now scientists at Yale and University of Texas Medical School-Houston have used cryo-electron ...
