DNA is only one among millions of possible genetic molecules

Biology encodes information in DNA and RNA, which are complex molecules finely tuned to their functions. But are they the only way to store hereditary molecular information? Some scientists believe life as we know it could ...

New catalyst efficiently produces hydrogen from seawater

Seawater is one of the most abundant resources on earth, offering promise both as a source of hydrogen—desirable as a source of clean energy—and of drinking water in arid climates. But even as water-splitting technologies ...

CRISPR: More than just for gene editing?

The gene-editing tool CRISPR has been heralded as a scientific miracle destined to eradicate diseases from sickle-cell anemia to cancer, or decried as "the genetic scissors that tailor the human gene pool," an ethically risky ...
