How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals ...

Proteins are the infinitely varied chemicals that make cells work, and science has a pretty good idea how they are made. But ...

Harnessing the power of a metabolite produced in the kidneys and absorbed from certain foods can mimic the health benefits ...

With a new mapping tool, Princeton engineers have revealed how a factory inside cells builds ribosomes, the machinery ...

Ribosomal RNA genes are essential for building ribosomes ... MMRd results in copying errors going uncorrected when DNA replicates and cells divide, causing high rates of additional mutations and an ...

Researchers have recovered and sequenced Mycobacterium lepromatosis genomes from 4,000-year-old human remains in Chile, providing the first molecular evidence of ancient leprosy in the Americas. The ...

Proteins are the infinitely varied chemicals that make cells work, and science has a pretty good idea how they are made. But a critical aspect ...

Researchers at the Johns Hopkins Kimmel Cancer Center and Department of Radiation Oncology and Molecular Radiation Sciences uncovered a new tumor-suppressive response that could lead to novel ...

Inside our cells, ribosomes—the tireless "protein factories" of life—have just shown off a new skill they haven't used in ...

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

Ribosomal proteins are proteins that constitute ribosomes. Ribosomal proteins may be structurally important within the ribosome, for instance in interacting with the RNA component (rRNA), and may ...
