Study: Phase separated droplets have many important functions in cells

Autophagy is a fundamental cellular process by which cells capture and degrade their own dysfunctional or superfluous components for degradation and recycling.

Researchers develop novel nanobodies against SARS coronavirus-2

An international research team led by the University of Bonn has identified and further developed novel antibody fragments against the SARS coronavirus-2. These "nanobodies" are much smaller than the classic antibodies used to treat US President Donald Trump, for example.

Study unravels the mystery of infectious virion formation

Researchers have for the first time identified the way viruses like the poliovirus and the common cold virus 'package up' their genetic code, allowing them to infect cells.

High-speed atomic force microscopy sheds light on structure, dynamics of intrinsically disordered proteins

Kanazawa University’s pioneering high-speed atomic force microscope technology has now shed light on the structure and dynamics of some of life’s most ubiquitous and inscrutable molecules – intrinsically disordered proteins.

Scientists observe detailed images of spike proteins in coronavirus

Coronaviruses, similar to the one that causes COVID-19 infection, are embedded with protein “spikes” that attach to receptors on their victims’ cells.

Researchers set a new record in X-ray microscopy

Researchers at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU), the Paul Scherrer Institute in Switzerland and other institutions in Paris, Hamburg and Basel, have succeeded in setting a new record in X-ray microscopy.

Researchers discover molecular mechanism of plant immune receptors

In a recent study, Alexander von Humboldt Professor Jijie Chai at the University of Cologne and his team together with MPIPZ researchers have succeeded for the first time in reconstructing the sequence of molecular events that activate an inactive plant immune receptor and thus mediate the death of the host cell.

Study determines 3D structure of molecular machine involved in placement of key proteins

Within a single cell, more than a quarter of all proteins are found in the membrane, in which they carry out crucial functions.

Biochemist discovers hidden cellular machinery essential for higher-order life

In his first year of graduate school, Rice University biochemist Zachary Wright discovered something hidden inside a common piece of cellular machinery that's essential for all higher order life from yeast to humans.

Researchers use super-resolution microscopy to study bacterial infection mechanisms

Expansion microscopy, abbreviated as ExM, allows scientists to image cells and their components with a spatial resolution down to 200 nm.

New study refutes a major cellular process in bacteria

Despite explanations in textbooks, a new study has discovered and elucidated a cellular process that has continued to remain a mystery for researchers.

Study shows how drug-like small molecules regulate the activity of ion channels

Researchers have recently discovered how the function of therapeutically relevant ion channels is regulated by drug-like small molecules.

Genetic modification in the ‘coat’ of fatal brain virus may allow it to escape antibodies

A genetic modification in the 'coat' of a brain infection-causing virus may allow it to escape antibodies, according to Penn State College of Medicine researchers.

Researchers reveal new details of crucial steps involved in the maturation of ribosomes

Ribosomes synthesize all the proteins in cells. Studies mainly done on yeast have revealed much about how ribosomes are put together, but an Ludwig-Maximilians-Universitaet (LMU) in Munich team now reports that ribosome assembly in human cells requires factors that have no counterparts in simpler model organisms.

Scientists elucidate the structure of ABC transporter protein

A high concentration of salt or sugar in the environment will dehydrate microorganisms and stop them from growing.

New removable coating cleans desalination membranes

A removable coating that can be used to clean desalination membranes has been developed by KAUST researchers. The nontoxic coating could provide a safer and more efficient alternative to harmful chemicals used to clean reverse osmosis systems for seawater desalination.

Study reveals 3D structure of crucial phage component in atomic resolution

Scientists from Berlin-based FMP are particularly interested in the tube employed by phages to insert their DNA into bacteria.

Study shows how coronavirus block cells’ ability to produce protective proteins

One of the novel coronavirus' most insidious tricks is that it can block the ability of cells to produce protective proteins without hindering its own ability to replicate.

Researchers reveal identity of the last unknown protein of autophagy

Drs. Nobuo Noda (Director) and Kazuaki Matoba (Senior Researcher) et al. at the Institute of Microbial Chemistry (BIKAKEN, Tokyo, Japan) discovered that Atg9, one of the proteins that function to mediate autophagy, has phospholipid-translocation activity (the lipid scramblase activity) between the two layers of the lipid bilayer and elucidated that the protein's activity brings about autophagosome membrane expansion.
