Stanford researchers unveil the key role of extrachromosomal DNA in cancer

A trio of research papers from Stanford Medicine researchers and their international collaborators transforms scientists' understanding of how small DNA circles - until recently dismissed as inconsequential - are major drivers of many types of human cancers.

Brain cells form multiple coordinate systems to guide behavioral actions

Neuroscientists have discovered brain cells that form multiple coordinate systems to tell us "where we are" in a sequence of behaviors.

New study reveals how tumor cells evade the immune system

It is comparatively easy to tell a cell's state of health: On their surface, cells present fragments of almost all the proteins they contain inside.

Exploring the circadian influence of immune cells on metabolic health and fat storage

Recent research reveals that the immune system interacts with the body's internal clock, influencing both fat storage and temperature regulation. These insights carry substantial implications for individuals with irregular work, eating, or sleep patterns driven by the demands of modern life.

CHiTA assay identifies functional twister ribozymes

The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA - a single-stranded molecule similar in many ways to DNA - like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, like a protein, it can also act as an enzyme, initiating or accelerating reactions.

Targeted bacteriophages offer standardized and scalable GI therapy

In a new study, researchers at the University of Copenhagen have been cultivating 'good viruses' from feces. The goal is to replace fecal capsules now being used in so-called fecal transplants. Their new technique has shown potential in studies with mice and the hope is that it will improve this life-saving treatment through standardization and pave its way toward mainstream medicine.

Deciphering the mechanisms of immune response with probabilistic graphical networks

Over the past two decades, new technologies have helped scientists generate a vast amount of biological data. Large-scale experiments in genomics, transcriptomics, proteomics, and cytometry can produce enormous quantities of data from a given cellular or multicellular system.

Research uncovers intrinsic factors influencing CAR-T cell success

Researchers from the Josep Carreras Leukaemia Research Institute have found that the efficacy of varni-cel, a CAR-T infusion product for B-ALL patients, is highly dependent on intrinsic features of the CAR-T cells themselves and their progression within the patient.
