DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Research reveals components of Sinbis virus ribonucleoproteins

To address this gap in research regarding the understanding of post-replicative alphavirus RNPs, scientists have created a novel proteome-wide approach known as viral RNA interactome capture (vRIC). This study is available in the bioRxiv* preprint server while awaiting peer review.

New algorithm provides a high-definition analysis of genome organization in single cells

Within the microscopic boundaries of a single human cell, the intricate folds and arrangements of protein and DNA bundles dictate a person's fate: which genes are expressed, which are suppressed, and -; importantly -; whether they stay healthy or develop disease.

New metagenome assembler can generate accurate DNA sequences

Metagenomics often involves sequencing DNA samples that can only be described as "tricky." Such DNA shows high heterogeneity, which can cause interspecies misassemblies.

Study traces the evolution of hepatitis B virus since prehistoric times

A study published in the journal Science traces the evolution of the hepatitis B virus from prehistory to the present, revealing dissemination routes and changes in viral diversity. Domingo Carlos Salazar García, researcher from the Prehistory, Archeology and Ancient History Department of the University of Valencia, has participated in this study led by the Max Planck Institute for the Science of Human History (Germany).

Scientists identify a new method to treat triple-negative breast cancer

A team of clinicians and scientists from the National Cancer Centre Singapore (NCCS), Singapore General Hospital (SGH) and A*STAR's Genome Institute of Singapore (GIS) has identified a novel method to treat triple-negative breast cancer (TNBC). They discovered that cancer cells switch between different cell states and are able to change from being less aggressive ('epithelial') to being more aggressive ('mesenchymal'), and vice versa.

Mouse brain atlas may help understand the complex circuits of the human brain

The circuits of the human brain contain more than 100 billion neurons, each linked to many other neurons via thousands of synaptic connections, resulting in a three-pound organ that is profoundly more complex than the sum of its innumerable parts.
