Physical virology shows the dynamics of virus reproduction

The reproductive cycle of viruses requires self-assembly, maturation of virus particles and, after infection, the release of genetic material into a host cell. New physics-based technologies allow scientists to study the ...

High-speed atomic force microscopy visualizes cell protein factories

Ribosomes are the complexes of ribonucleoproteins at the heart of protein synthesis in cells. However, in the absence of conclusive evidence, how these complexes operate has been open to debate. Now, Hirotatsu Imai and Noriyuki ...

The evolution of single amyloid fibrils into microcrystals

Amyloids refer to abnormal fibrous extracellular and proteinaceous deposits found in organs and tissues that form insoluble constructs that are resistant to degradation. Their formation can accompany disease, where each disease ...

High-speed atomic force microscopy takes on intrinsically disordered proteins

Our understanding of biological proteins does not always correlate with how common or important they are. Half of all proteins, molecules that play an integral role in cell processes, are intrinsically disordered, which means ...

Two dimensional heterostructures composed of layers with slightly different lattice vectors

New periodic structures known as moiré lattices can be observed in two-dimensional (2-D) heterostructures containing layers with slightly different lattice vectors, which can in turn support new topological phenomena. It ...

BioAFMviewer software for simulated atomic force microscopy of biomolecules

Nowadays nanotechnology allows one to observe single proteins at work. Under atomic force microscopy (AFM), e.g., their surface can be rapidly scanned, and functional motions monitored, which is of great importance for applications ...

Researchers invent method to 'sketch' quantum devices with focused electrons

It has long been a dream to invent new materials from the "top down" choosing which atoms go where to engineer properties of interest. A technique created by researchers out of the Department of Physics and Astronomy enables ...

Fine tuning the "twist" between 2-D materials in van der Waals heterostructures to help accelerate next gen electronics

A group of international researchers at The University of Manchester have revealed a novel method that could fine tune the angle—"twist"—between atom-thin layers that form exotic manmade nanodevices called van der Waals ...
