Lab one step closer to understanding how life started on Earth

How did life begin on Earth and could it exist elsewhere? Researchers at Simon Fraser University have isolated a genetic clue—an enzyme known as an RNA polymerase—that provides new insights about the origins of life. ...

Researchers invent new gene-editing tool

Researchers from the University of Illinois Chicago have discovered a new gene-editing technique that allows for the programming of sequential cuts—or edits—over time.

At the core of the integrator complex

Gene expression is a highly regulated process that involves several steps. These include transcription of DNA instructions into RNA, removal of non-coding segments from the RNA message, and its subsequent translation into ...

Study offers new insights into fragile X syndrome

A new study shows that many abnormalities in fragile X syndrome cells are related to glitches with one of the body's major quality control systems. Published in Nature Cell Biology, the research provides fresh insight into ...

Regulating the ribosomal RNA production line

The enzyme that makes RNA from a DNA template is altered to slow the production of ribosomal RNA (rRNA), the most abundant type of RNA within cells, when resources are scarce and the bacteria Escherichia coli needs to slow ...

A closer look at how immune cells attack and heal

Macrophages—immune cells that both fight infections and fix the damage they cause—are often placed into two categories: those that increase inflammation (known as "M1") to attack, and those that decrease inflammation ...

New videos show RNA as it's never been seen

A new Northwestern University-led study is unfolding the mystery of how RNA molecules fold themselves to fit inside cells and perform specific functions. The findings could potentially break down a barrier to understanding ...
