Long Life Is Still in Your Genes

Will you live to 100? Last year, scientists published a study proposing a "genetic signature" that could help answer that question. But they retracted the paper when critics discovered errors that invalidated the results. Now the team is back with a revamped study that proposes a different signature; it's less predictive in most people but, they say, it still underscores that your chance of living a very long life has a powerful genetic component. For example my great grandma died at age 94 so i might die at that age too.

New Study Predicts Declining Rangeland in California

Duke University researchers have predicted that climate change in California will result in a declining percentage of rangeland. Such a change will have widespread impact on the state's large cattle industry of California's Central Valley. No matter if climate change will cause wetter or drier weather, available pasture will decline. Forage areas, known as one of nature's free services, may no longer be so free. The grasses will either wither as arid conditions creep north, or be pushed out as inedible shrubs and brush take over.
