A cryptic part of DNA helps keep a species' mutations in check until they become useful.
The molecules that make up life may have arrived from space, and many are chiral.

A new theory could explain why the key molecules of life - DNA and RNA - only come in one of two possible forms.

Understanding how the flu virus copies itself could open a way to killing it.
A virus is essentially an information system (encoded in DNA or RNA) surrounded by a protective coat.
Humans have a deep history of viral infections, the evidence for which dates back to ancient DNA from Egyptian mummies.

Study suggests that comets and meteorites could have seeded planets beyond our own solar system with life.
There’s more to our DNA than just genes.
microRNA used to be dismissed as "junk DNA", but it plays an important role regulating the other genes in our genome.
CRISPR-Cas systems provide a new way to target pathogenic bacteria, without some of antibiotics’ downsides.

A naturally-occurring system discovered in bacteria holds promise as a way to fight pathogens – very specifically and without the risk of antibiotic resistance.
Hydrogen peroxide – widely used in hair bleach – may also hold the key to life on early Earth.

A chemical found in hair bleach may help answer questions about the origins of life and explain why new life does not emerge on modern Earth. Hydrogen peroxide may have helped transform RNA (ribonucleic…
RNA is similar to DNA in lots of ways. But an extra oxygen atom makes all the difference.

Our genetic material is encoded in DNA (deoxyribonucleic acid). DNA is famous. But you may also have also heard of RNA (ribonucleic acid). So, what is RNA, and what is it good for? Quite a lot really…
Brain tumours communicate with other cells in a similar way to twitter, according to a new study from the Brain and Mind…
A new flu detection test promises the ability to be carried in a first-aid kit and to be used with the ease of an iPhone…
