Ultrasensitive transistor for herbicide detection in water

A new polymer-based, solid-state transistor can more sensitively detect a weed killer in drinking water than existing hydrogel-based fluorescence sensor chips. The details were published in Chemistry–A European Journal.

Identifying compound classes through machine learning

Everything that lives has metabolites, produces metabolites and consumes metabolites. These molecules arise as intermediate and end products from chemical processes in an organism's metabolism. Therefore, they not only have ...

Escape from Mars: How water fled the red planet

Mars once had oceans but is now bone-dry, leaving many to wonder how the water was lost. University of Arizona researchers have discovered a surprisingly large amount of water in the upper atmosphere of Mars, where it is ...

Ice-binding molecules stop ice growth, act as natural antifreeze

Certain molecules bind tightly to the surface of ice, creating a curved interface that can halt further ice growth. Some insects, plants, and sea-dwelling creatures contain protein molecules of this type that act as natural ...

Identifying biomolecule fragments in ionising radiation

When living cells are bombarded with fast, heavy ions, their interactions with water molecules can produce randomly scattered 'secondary' electrons with a wide range of energies. These electrons can then go on to trigger ...
