Satellite radar gauges water levels in Louisiana wetlands
...lucky that the tracks fall on the wetlands. We may try using other radar altimeter satellites to improve the spatial resolution of the wetland study. However, the primary limitation for TOPEX/Poseidon is its narrow measurement swath on the ground," Shum said. The satellite gathers data in a strip, up to ...Small, smaller, smallest -- The plight of the vaquita

On 29 December 2005 the Ministry of Environment declared a Vaquita Refuge that contains within its borders approximately 80% of all verified vaquita sighting positions.

Warnock said that some people try to get their poinsettias to turn red again the following year, but it's nearly impossible because the plant's exposure to the light has to be completely controlled.

Though the technique has been used on herbaceous plants in controlled environments, Johnsen's experiment represents the first test of the method on trees and, in p...P(acman) takes a bite out of deciphering Drosophila DNA
