Study of Northern Alaska Could Rewrite Arctic history

  HANOVER, N.H. – Parts of Alaska’s mountainous Brooks Range were likely transported from Greenland and a stretch of the Canadian Arctic much farther to the east, according to a series of Dartmouth-led studies detailing over 300 million years of Arctic geologic history. The finding updates the geological evolution of the Arctic Ocean and could […]

Seaweed Farmers in Alaska Gear Up for Large Haul

The largest commercial harvest of seaweed in Alaska is taking place this month. Blue Evolution, a California-based company that cultivates, harvests and distributes Alaska-grown seaweed, is expected to haul in up to 200,000 pounds from waters near Kodiak Island within the next two weeks. Previous harvests have been a fraction of that size, but, as […]

Large-Scale Study of Genetic Data Shows Humans still Evolving

In a study analyzing the genomes of 210,000 people in the United States and Britain, researchers at Columbia University find that the genetic variants linked to Alzheimer’s disease and heavy smoking are less frequent in people with longer lifespans, suggesting that natural selection is weeding out these unfavorable variants in both populations. Researchers further find […]
