Fractures as the main pathways of water flow in temperate glaciers

Article Abstract:

Video games from 48 boreholes drilled into the small Swedish glacier, Storglaciaren, which shows the glacier's hydrological system being dominated by fractures that convey water at slow speeds, is analyzed. Fractures provide the main pathways for surface water to reach deep within the glacier whereas tubular conduits probably form only in special circumstances.

Water-repellent legs of water striders

Article Abstract:

The water striders have remarkable non-wetting legs that enable them to stand effortlessly and move quickly in water. This is a feature of surface tension effect caused by secreted wax and it has a spherical structure of legs covered by large numbers of oriented tiny hairs with fine nanogrooves that is more important in inducing water resistance.

The water cycle freshens up

Article Abstract:

A study reveals that the rivers are delivering increasing amounts of fresh water to the ocean. The cause seems to be the influence that higher concentrations of atmospheric carbon dioxide are having on water use by plants.
