In an unearthly series of events, the USGS has created man-made moon dirt, or regolith, to help NASA prepare for upcoming moon explorations. Four tons of the simulant is expected to be made by this summer of 2009 and turned over to the scientific community involved in lunar exploration.
While still common at higher elevations, iiwi are extremely susceptible to avian malaria. Mortality is as high as 90% after exposure to a single infective mosquito bite under laboratory conditions.
While the susceptibility of endangered akepa honeycreepers to avian malaria is unknown, it is likely very high given their current restriction to the highest elevation forests on the island of Hawaii.
During the past decade populations of this honeycreeper have begun to rebound at lower elevations on most of the main Hawaiian Islands, in spite of high prevalence of infection with avian malaria. Natural selection for resistance to avian malaria is the leading explanation for this rebound and...
