Scientists have discovered the cremated skeleton of a Paleoindian child in the remains of an 11,500-year-old house in central Alaska. The findings reveal a slice of domestic life that has been missing from the record of the region’s early people, who were among the first to colonize the Americas.

The discovery, by Ben Potter of the University of Alaska Fairbanks and colleagues, appears in the 25 February issue of the journal Science.

Increasing numbers of birds, mammals and amphibians have moved closer to extinction in the last several decades—but not as far as they would have if no conservation measures had been enacted, researchers report in ScienceExpress this week.

Tanzania and Zambia are petitioning to downgrade the conservation status of elephants and allow the sale of tons of stockpiled ivory, but researchers are warning that such a ruling could endanger the mammoth mammals by encouraging more illegal poaching.
