Through a large-scale study with so-called geolocators, researchers were able to uncover some of the mysteries surrounding the phenomenon of the blackcap's bird migration.
A new study shows that increased heat from Arctic rivers is melting sea ice in the Arctic Ocean and warming the atmosphere.
A long-standing mystery in the study of glaciers was recently and serendipitously solved. A trigger was identified for some of the largest floods on Earth -- those emerging suddenly and unpredictably from beneath glaciers or ice caps.

Before their big journey, many birds molt their bright feathers, replacing them with a more subdued palette. Watching this molt led scientists to wonder how feather color changes relate to the migrations many birds undertake twice each year.
A new path design for bicycles at a railway crossings cuts bike crashes. A jughandle design realigns the bicycle approach to about 60 degrees, virtually eliminating the risk of a rider's tire being caught in the gap between the rail and the pavement, a cause of serious crashes. This significant finding varies from previous design recommendations of a 90-degree approach.
Reporting unexpected processes, chemists say they have discovered how an enzyme known as UCH37 regulates a cell's waste management system.
People tend to think that pretty-looking food is healthier (e.g., more nutrients, less fat) and more natural (e.g., purer, less processed) than ugly-looking versions of the same food.
