The internet erupted in controversy over Felisa Wolfe-Simon and colleagues’ claim of a microbe thriving on arsenic. Nearly 15 ...

Not only does Bennu contain evidence of ancient pools of liquid water — it also carries minerals crucial to life, amino acids, and the five nucleobases for DNA and RNA. As asteroids crash into ...

This definition encompasses the dynamic and complex nature of life, emphasizing its ability to adapt and evolve. Life on ...

Learning about your genetics and ancestry is easier than ever. All you need to do is choose from the many DNA ancestry tests available online, receive your kit and send back the required DNA samples.

Comparison of that ancient DNA with modern human DNA showed that the two species had interbred and that people today still carry the genetic fingerprint of that intermixing. Since then ...

DNA polymerases carry out crucial functions in many DNA metabolic processes. Polymerases catalyse the addition, using a template, of complementary nucleotides to the 3′ end of DNA primer strands.

Scientists have long believed they understood how life’s genetic code evolved, but new research upends that assumption. By ...

DNA (deoxyribonucleic acid) is the nucleic acid polymer that forms the genetic code for a cell or virus. Most DNA molecules consist of two polymers (double-stranded) of four nucleotides that each ...

A new paper released today documents the first soil, airfall dust, and rock fragment samples collected by NASA for return ...

Of course, though, testing a child's parentage based on physical features is far too subjective — that's typically where DNA tests come in. Such tests can offer a far more scientific way of ...
