Shelf ice, as found in Antarctica, refers to giant floating ice sheets that can span thousands of square kilometres. Pieces break off at their edges which form icebergs in the ocean. In order to more effectively predict these break-offs, in a process known as calving, Julia Christmann from the University of Kaiserslautern (TU) has developed mathematical models in cooperation with the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). On the basis of physical factors, it is claimed that these models can be used to predict when and where the ice may collapse. This is important particularly for research teams situated on the ice shelf.

As Hurricane Harvey continued to strengthen, NASA analyzed the storm’s rainfall, cloud heights and cloud top temperatures. NASA’s GPM and Aqua satellite provided information while an animation of GOES-East satellite imagery showed Harvey’s progression toward the Texas coast. 

Harvey's intensification has been aided by movement through an environment that includes low vertical wind shear and the warm waters in the Gulf of Mexico.

Tinnitus, a chronic ringing or buzzing in the ears, has eluded medical treatment and scientific understanding. A new study by University of Illinois researchers found that chronic tinnitus is associated with changes in certain networks in the brain, and furthermore, those changes cause the brain to stay more at attention and less at rest.

Within the next century, rising ocean temperatures around the Galápagos Islands are expected to make the water too warm for a key prey species, sardines, to tolerate. A new study by Wake Forest University biologists, published in PLOS One Aug. 23, uses decades of data on the diet and breeding of a tropical seabird, the Nazca booby, to understand how the future absence of sardines may affect the booby population.
