Worries and outcry over injuries and a death in the Mount Marathon Race dominated Alaska news this week, as the search was called off for a missing Anchorage man who simply vanished in the middle of the July Fourth race. Craig Medred offers comprehensive coverage of the legendary race's first-ever death and offers a glimmer of hope to the loved ones of race survivor Matt Kenney, who's still hospitalized with traumatic brain injury. And another tragedy on the Kenai Peninsula: former Alaska lawmaker Cheryll Heinze was killed this week in a freak float plane accident on Beluga Lake.
It was also a big week in Alaska science news. A study concludes that indigenous American populations from the Arctic to southern Chile all share ancestral genes of a common "First People" that migrated across the Bering Strait land bridge that once connected Alaska with Eurasia. And yet another study for the first time confirms that aurora borealis -- one of many cherished benefits that comes with life in the Last Frontier -- emits sound when dancing across the Far North sky.
These and other stories shaped news in the 49th state this week. Here's some of our best reporting.
