Large boulders help shape huge canyons, researchers find

Anyone who enjoys whitewater rafting in places like the Colorado River owes a debt of gratitude to the enormous boulders that create the foaming undulation known as rapids, and new research appears to shed more light on how ...

New lidar instruments peer skyward for clues on weather and climate

Researchers have developed a set of diode-based lidar instruments that could help fill important gaps in meteorological observations and fuel a leap in understanding, modeling and predicting weather and climate. The instruments ...

Just how much does enhancing photosynthesis improve crop yield?

In the next two decades, crop yields need to increase dramatically to feed the growing global population. Wouldn't it be incredibly useful if we had a crystal ball to show us what are the best strategies available to increase ...

Hydrogels change water and solute dynamics

Hydrogels form tiny, water-filled pores with diameters so small that molecular-level studies can be difficult. Moreover, the motion of water molecules and dissolved ions is so fast that they are difficult to follow. Therefore, ...

Atomic-scale capillaries block smallest ions, thanks to graphene

Researchers at The University of Manchester's National Graphene Institute in the UK have succeeded in making artificial channels just one atom in size for the first time. The new capillaries, which are very much like natural ...
