According to the RNA world hypothesis, life began when RNA molecules evolved the ability to make more copies of themselves. Now we have discovered an RNA molecule that is almost capable of this – it ...

We the authors are retracting this Article because our efforts to repeat and follow up on the results have been unsuccessful. Specifically, we have been unable to reproduce observations suggesting ...

A molecule so small it could fit on a Post-it note of genetic code has just pulled off something scientists have chased for ...

Antisense oligonucleotides (ASO) hold great promise for pharmacotherapy. Now, researchers at Tokyo Medical and Dental University (TMDU) and Ionis Pharmaceuticals, advancing their earlier work on a ...

Scientists from the Skoltech Center for Life Sciences (CLS) led by professor Dmitri Pervouchine and their colleagues from Russian and international laboratories used molecular and bioinformatics ...

Antisense oligonucleotides (ASOs) are small, single-stranded molecules that can suppress the expression of targeted genes and thereby achieve therapeutic effects. However, many ASO-based drug ...

Researchers in China have developed a new method that allows them to insert long stretches of DNA into a genome. The process, named GRAND editing, is one of a handful of new systems aimed at using two ...

Even those who doubt the RNA World hypothesis may be hard-pressed to argue against it. Consider the predicament faced by a team of scientists at Scripps Research. They suspected that RNA was a poor ...

One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...
