Hot but not bothered: Warm soils favor microbes with small genomes

Centralia, Pa., sits above rich subterranean coal seams, which made the town a mining center for about a century. In 1962, the seams were accidentally ignited by burning garbage, turning the coal from a commodity into a liability. Driven away by fire-associated hazards and particulate air pollution, all but a few human residents have long since abandoned the town. However, a new study reveals that the same isn’t true for all forms of life: A diverse population of microbial life resides in Centralia’s hot soils. These heat-tolerant microbes are offering scientists novel insights into the composition and character of soil microbial communities and resilience in response to dramatic ecosystem change.

Scientists sequence oldest modern human genome to date

A chance fossil find along a Russian river has provided researchers with the oldest genomic data ever sequenced from a modern human. The fossil, a nearly complete left femur, was pulled from a bank along the Irtysh River near the Ust’-Ishim district in western Siberia in 2008 by a Russian artist before it made its way to scientists.

Down to Earth With: Molecular biologist Sarah L. Anzick

In May 1968, when Sarah L. Anzick was 2 years old, the 12,600-year-old remains of a male toddler were discovered at the base of a bluff on her family’s ranch near Wilsall, Mont. The Anzick infant — one of just a handful of ancient skeletons to have been found in North America and the only known Clovis burial site —  had been carefully buried with more than 100 stone and bone tools.
