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

NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission.

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.

Discover how scientists blend biology, synthetic biology, and astrobiology to speculate on alien life forms, focusing on the shared characteristics that might transcend Earth's biosphere. One of the b ...

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

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.

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 ...

Using DNA nanorobots, the researchers were able to influence the shape and functionality of these synthetic cells. New transport channels for proteins and enzymes DNA nanotechnology is one of ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means ...

The discovery is a capstone achievement for NASA, which went to great lengths to secure and deliver asteroid samples from ...

Asteroids, small airless bodies within the inner solar system, are theorized to have contributed water and chemical building blocks of life to Earth billions of years ago. Although meteorites on Earth ...
