A new method can test the activity of thousands of RNA enzymes, called ribozymes, in a single experiment. The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA ...

In most modern cells, DNA stores the genetic blueprint, and proteins replicate, repair and build from those blueprints. At the same time, proteins require instructions from DNA to be made in the first ...

Researchers have now uncovered the 3D structure of the RNA enzyme SAMURI. Their study provides insights into the development of ribozymes and the evolution of catalytically active RNA. Researchers led ...

An international research team led by TU Darmstadt Professor Beatrix Süß, working in close collaboration with partners in ...

Study reveals how an RNA enzyme drives the postnatal switch from glucose to fatty acids in heart cells, highlighting ketogenesis as essential for metabolism. Study: The tRNA methyltransferase Mettl1 ...

DALLAS – June 29, 2026 – An RNA-modifying enzyme linked to cancer and neurological disorders selects its targets by recognizing specific RNA shapes and sequences, according to a study by UT ...

Rice researchers have developed an improved version of Cas13a that could make it easier to detect HIV and other RNA viruses ...

Autoimmune diseases now affect a substantial and growing share of the global population, and yet most current therapies blunt the immune system broadly rather than correcting the specific molecular ...

Parkinson's disease (PD) is a neurodegenerative disorder in which the α-synuclein protein abnormally aggregates within brain cells, causing neuronal damage. Through international collaboration, ...

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 ...

The novel Cleavage High-throughput Assay (CHiTA) developed at Penn State provides a scarless method to characterize thousands of diverse small self-cleaving RNA enzymes, called twister ribozymes, in a ...
