Dupple writes: On Friday, the High Court of London issued a ruling that said that one of Motorola’s patents covering technology to synchronize messages across several devices should be invalidated. Originally, the patent covered the synching of messages across multiple pagers, but recently Motorola has used the patent in lawsuits against Apple and Microsoft for using similar message-syncing services in iCloud and on the Xbox, respectively.
The presiding Judge Richard Arnold declared Motorola's patent invalid and said it should be revoked because the patent (which has a priority date from 1995, but was issued in 2002) contained technology that “was obvious to experts. in the field at the time.”

Eventually, Oahu’s Koolau and Waianae mountains will dwindle to little more than a flat, low-lying island like Midway. While erosion is certainly a guilty party, researchers contend that the mountains of Oahu are, in fact, dissolving from within.
Researchers spent several months collecting samples of groundwater and stream water to determine which source removed more mineral material. They also put to use surface water estimates from the U.S. Geological Survey to calculate the quantity of mass that vanished from the island each year. Researchers point out that Oahu is actually rising in elevation at a slow but steady rate due to plate tectonics.
“The Big Island is so large that it actually depresses the ocean crust–kind of like a dimple on a golf ball,” BYU geologist Steve Nelson told The Science Recorder via email. “Oahu is close enough to the Big Island such that as the plate drifts to the northwest, Oahu is moving up and out of the side of the dimple. Kauai is far enough away (and older) that it has moved out of the dimple. The estimate of the duration of rising is based on the time it will take for Oahu to drift to where Kauai is now.”
Mr. Nelson and colleagues believe that Oahu will continue to grow for as long as 1.5 million years. Beyond that, the force of groundwater will eventually win and Oahu will begin its transformation to a flat, low-lying island like Midway. Researchers are confident that it will be a very long time before Oahu begins its descent.

The only way to maintain the current chemical environment in which reefs now live, the study suggests, would be to deeply cut emissions as soon as possible. It may even become necessary to actively remove carbon dioxide from the atmosphere, say with massive tree-planting efforts or machines.
