It has genes for ribosomes, tRNAs, and mRNAs. These components are the scaffolding of life: the tools by which cells read ...

Scientists are warning that a project aiming to build human DNA from scratch could lead to new types of warfare and is a ...

New imaging tools reveal how within an hour of infection, the virus begins to alter our chromosomes to kick-start its own replication.

In nature as well as in our bodies, bacteria predominantly live as organized communities called biofilms. These structures play a central role in antibiotic resistance mechanisms. In a ...

A study of twins reveals two gut bacteria linked to multiple sclerosis, offering new targets for future treatments.

Mitochondria have primarily been known as the energy-producing components of cells. But scientists are increasingly ...

Mitochondria are not just the powerhouses of the cell – they are the immune system’s watchtowers, alert to even the faintest metabolic signals of bacterial invaders. As researchers’ understanding of ...

Imported seafood may be spreading colistin-resistant “superbugs” into U.S. kitchens as a new study warns of rising antibiotic ...

Discover how genetics and diet shape the human gut microbiome, influencing health, metabolism, and disease risk. Explore ...

Their findings, published in Science in a paper titled, “ Telomeric transposons are pervasive in linear bacterial genomes,“ reveal that transposons can target and insert themselves into ...

DNA gyrase operates like a tiny molecular machine, carefully twisting and stabilising bacterial DNA. This twisting, known as supercoiling, is similar to winding an elastic band: as it twists, it ...

Bacteria and their viruses have been locked in battle for eons, as viruses try to inject their DNA into the bacterial genome and bacteria devise cunning methods (e.g. CRISPR) to defend themselves.
