Researchers use molecular dynamics simulations to identify secrets of SARS-CoV-2 virus

The virus wreaking havoc on our lives is an efficient infection machine. Comprised of only 29 proteins (compared to our 400,000), with a genome 1/200,000 the size of ours, SARS-CoV-2 is expertly evolved to trick our cells to contribute its machinery to assist in its propagation.

Elucidating IDP behaviour on crowded membranes

IDPs are proteins that contain stretches of amino-acid sequence that are flexible and do not comprise stable structure in isolation. This is in contrast with a more traditional view of proteins as largely occupying a stable native structure that correlates with functions such as enzyme activity or binding.

NanoTracker™ Optical Tweezers system used at Leiden University to study the organisation of genomic DNA

JPK Instruments, a world-leading manufacturer of nanoanalytic instrumentation for research in life sciences and soft matter, reports on the use of the NanoTracker™ Optical Tweezers system in the Laboratory of Molecular Genetics in the Leiden Institute of Chemistry at Leiden University.

Novel sensor selectively screens single molecules passing through nanopores

A novel type of sensor, based on nanometer-scale pores in a semiconductor membrane, is a step closer to practical use in applications such as analyzing the protein contents of a single cell. Researchers pioneering single-molecule nanopore sensor technology at the Technische Universit-t M-nchen (TUM) have shown its potential through a succession of experiments over the past few years.

UCSB physicists create microscopic device to help biologists understand protein folding

Physicists at UC Santa Barbara have created a microscopic device to assist biologists in making very fast molecular measurements that aid the understanding of protein folding. This development may help elucidate biological processes associated with diseases such as Alzheimer's and Parkinson's. Since proteins in the body perform different functions according to their shape, the folding process is considered a key area of study.

TUM biophysicists map changes in energy landscape of zipper-like protein molecule

Biophysicists at TUM, the Technische Universitaet Muenchen, have published the results of single-molecule experiments that bring a higher-resolution tool to the study of protein folding. How proteins arrive at the three-dimensional shapes that determine their essential functions - or cause grave diseases when folding goes wrong - is considered one of the most important and least understood questions in the biological and medical sciences.

Researchers show evidence of 'memory' in cells and molecules

Research to be reported October 29 in the journal Proceedings of the National Academy of Sciences (PNAS) provides evidence that some molecular interactions on cell surfaces may have a "memory" that affects their future interactions.

Promising new line in anti-cancer therapy

A promising new line in anti-cancer therapy by blocking the molecular motors involved in copying genetic information during cell division is being pursued by young Dutch researcher Dr. Nynke Dekker in one of this year's EURYI award winning projects sponsored by the European Science Foundation (ESF) and the European Heads of Research Councils (EuroHORCS).
