4-D imaging with liquid crystal microlenses

Most images captured by a camera lens are flat and two dimensional. Increasingly, 3-D imaging technologies are providing the crucial context of depth for scientific and medical applications. 4-D imaging, which adds information ...

Discovery of rare lava lake on remote sub-Antarctic island

A team of scientists has discovered a rare lava lake on a remote and inaccessible sub-Antarctic island. There are around 1500 land-based volcanoes on Earth, but despite the popular perception of steaming bubbling lava pools ...

Remote sensing of toxic algal blooms

Harmful algal blooms in the Red Sea could be detected from satellite images using a method developed at KAUST. This remote sensing technique may eventually lead to a real-time monitoring system to help maintain the vital ...

Algorithms to enhance forest inventories

An EPFL doctoral student has come up with methods to map out forests more effectively using aerial remote sensing, in support of on-the-ground forest inventories.

Piecing together our planet pixel by pixel

At first glance, the high-resolution images of the polygons look like the lacy skin of a cantaloupe melon – perhaps not what would be expected of images of the Arctic tundra. But this characteristic feature of the tundra ...
