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 ...

A cheaper way to scale up atomic layer deposition

Chemical engineers at EPFL have developed a new method for atomic layer deposition, a technique commonly used in high-quality microelectronics. The new method can be used in materials with larger surfaces much more cheaply ...

New understanding of antibiotic synthesis

Researchers at McGill University's Faculty of Medicine have made important strides in understanding the functioning of enzymes that play an integral role in the production of antibiotics and other therapeutics. Their findings ...

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 ...

Scientists take strides towards entirely renewable energy

Scientists from Trinity College Dublin have taken a giant stride towards solving a riddle that would provide the world with entirely renewable, clean energy from which water would be the only waste product.

New polymer releases molecular cargo in response to force

Caltech scientists have developed a new kind of polymer that can carry a chemical payload as part of its molecular structure and release it in response to mechanical stress. The chemical system they have developed could one ...
