Researchers develop 3D imaging technique to visualize damaged lung tissue after severe COVID-19

Physicists at the University of Göttingen, together with pathologists and lung specialists at the Medical University of Hannover, have developed a three-dimensional imaging technique that enables high resolution and three-dimensional representation of damaged lung tissue following severe Covid-19.

Using engineered off-the-shelf therapeutic T cells to fight cancer

Personalized cancer treatments are no longer just options of the future. In the past few years, researchers have made significant progress in 'teaching' the body's immune T cells to recognize and kill specific cancer cells, and human clinical trials have shown that this approach can successfully eliminate tumors.

Cryo-EM experiments offer important clues to chicken pox infection

Despite decades of study, exactly how herpesviruses invade our cells remains something of a mystery. Now researchers studying one herpesvirus, the varicella zoster virus (VZV) that causes chicken pox, may have found an important clue: A key protein the virus uses to initiate infection does not operate as previously thought, researchers at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory report August 18 in Nature Communications.

New technique enables real-time observation of influenza A hemagglutinin during viral entry

Unlike living organisms, to avoid extinction, viruses need to hijack living host machineries to generate new viruses.

Researchers reveal molecular workings of a key system in learning and memory formation

One of the new realities in biomedical research is that it's increasingly difficult to use a general approach to score advances. Now, investigations into disease mechanisms, for example, are often conducted at the molecular level by specialists who dedicate years to interrogating a single protein or signaling pathway.

Finned nanoporous catalyst facilitates molecular transport

Thousands of chemical processes used by the energy industry and for other applications rely on the high speed of catalytic reactions, but molecules frequently are hindered by molecular traffic jams that slow them down.

High-speed atomic force microscopy reveals diverse amyloid structures and dynamics

In the human body, proteins sometimes occur in fibrillar aggregates called amyloids. Although certain amyloids are known to have a biological function, amyloid formation is often associated with pathologies, including Alzheimer's and Parkinson's diseases.

New method to detect rare circulating tumor cells in blood samples

Metastasis - the development of tumor growth at a secondary site - is responsible for the majority of cancer-related deaths. It occurs when the primary tumor site sheds cancerous cells which are then circulated through the body via blood vessels or lymph nodes.

Deep learning algorithm can identify genetic alterations from routine histological images of tumors

Researchers at the University of Chicago Medicine Comprehensive Cancer Center, working with colleagues in Europe, created a deep learning algorithm that can infer molecular alterations directly from routine histology images across multiple common tumor types.

Novel label-free imaging method can differentiate active T cells from those off duty

T cells are the immune soldiers at the frontlines of the battle with infiltrating pathogens that seek to cause disease. A new study published in Nature Biomedical Engineering describes a novel label-free imaging technique that can differentiate active T cells from those off duty.

Study provides insight into evolution of amyloid-β oligomer with temporary salt crystals

Alzheimer's disease is the leading cause of dementia worldwide and a major cause of disability. Now, researchers at Osaka University and Hokkaido University have shown that repeated precipitation-dissolution events of salt crystals do occur even at low salt concentrations in nanoscales, and that it can accelerate the aggregation of the neurotoxic amyloid-β peptides implicated in its pathogenesis.

Proximity of mutated cells guides the initiation of tumor

Scientists have revealed a key factor that influences whether malignant cells will grow to form a tumor, in a new study published today in eLife.

Advanced cryo-EM imaging reveals high-resolution structure of viral RNA replication complex

For the first time, scientists at the Morgridge Institute for Research have generated near atomic resolution images of a major viral protein complex responsible for replicating the RNA genome of a member of the positive-strand RNA viruses, the large class of viruses that includes coronaviruses and many other pathogens.

'Smart nanosheets' can help quickly isolate new types of proteins from mixtures

An interdisciplinary team from Frankfurt and Jena has developed a kind of bait with which to fish protein complexes out of mixtures.

Researchers determine how SARS-CoV-2 inhibits protein synthesis

Researchers from Munich and Ulm have determined how the pandemic coronavirus SARS-CoV-2 inhibits the synthesis of proteins in infected cells and shown that it effectively disarms the body's innate immune system.

Pioneering method reveals the dynamics of HIV Gag lattice structure

Viruses are scary. They invade our cells like invisible armies, and each type brings its own strategy of attack. While viruses devastate communities of humans and animals, scientists scramble to fight back.

Structure of the SARS-CoV-2 spike protein provides clues to its evolution

Researchers at the Francis Crick Institute have characterized the structure of the SARS-CoV-2 spike protein as well as its most similar relative in a bat coronavirus. The structures provide clues about how the spike evolved and could help inform vaccine design.

Real-time tracking of protein filaments in the nuclear pore complex

In human cells, the nucleus is enclosed by a structure called the nuclear pore complex (NPC). It acts as a 'gatekeeper' controlling the transport of molecules between the nucleus and the surrounding cytoplasm (the protein-containing solution in the inside of a cell).
