Gene linked to rapid Alzheimer's onset

St. Louis -- U.S. researchers say they've identified a genetic marker that could be used to predict how fast Alzheimer's disease will develop in patients.

Scientists at Washington University in St Louis say a gene variation associated with aggressive progression of Alzheimer's was found in patients with high levels of a protein linked to the disease, Britain's Daily Telegraph reported Friday.

They studied DNA variations in 846 patients with elevated levels of the protein.

"We have looked at data from three separate, international studies, and in all three we found the same association," study author Carlos Cruchaga said.

HTC Evo 4G is off to a fast start

Overland Park, Kan. -- U.S. telecommunications firm Sprint said sales of the HTC Evo 4G smart phone have been faster, by far, than any of its previous offerings.

The Android-based phone was launched Friday. In one day it outsold the first three days of the Samsung Instinct and Palm Pre phones combined, PCWorld reported Monday.

Sprint did not give out the number of Evo 4G phones it sold.

The phone was offered at 22,000 retail outlets, including Best Buy, RadioShack and Walmart stores, some of which ran out of the phone temporarily.

Kevin Packingham, Sprint's senior vice president of product development, said the phone had "more than lived up to our expectations that it would be one of the most anticipated technology products of the year."
