Envisat and ERS-2 reveal hidden side of Hurricane Rita

...exico, ESA's Envisat satellite's radar was able to pierce through swirling clouds to directly show how the storm churns the sea surface. This image has then been used to derive Rita's wind field speeds. Envisat acquired this Advanced Synthetic Aperture Radar (ASAR) image at 0344 UTC on 22 September (2345 o...

Techniques available to detect soil that inhibits destructive soybean pest

...ecies use a short, hypodermic needle-like mouth to pierce soybean roots and suck out the nutrients. As the adult female ages, she fills with eggs, turns yellow and then brown to become the nematode cyst. At that point her body is a case to protect hundreds of eggs while they mature, hatch into juveniles and...

UC Berkeley researchers create a biologically-inspired artificial compound eye

... eye's dome. The end result is that the waveguides pierce the resin at angles that head toward the center of the dome, just like the converging ommatidia of an insect eye. Because the microlenses create the waveguides, each microlens is perfectly aligned with its waveguide. The self-alignment, self-writing...

Satellites shed light on global warming

...quality images of ice sheets because it is able to pierce through clouds and darkness. In addition to mapping ice boundaries, Rott used repeat-pass ASAR image data to map the flow velocities of glaciers. All the glaciers, where the buttressing ice had disappeared, have accelerated significantly. The ret...
