Humans Riddled with Rare Genetic Variants
from Nature News
By sequencing more people more thoroughly than ever before, researchers have affirmed that rare genetic variants--those carried by fewer than five people in a thousand--are widespread and likely to have an important role in human health.
Two studies published today in Science find that most human genetic variants are rare, and that rare variants are more likely than common ones to affect the structure or function of proteins, and therefore to have biological or medical consequences. The papers, along with another study published last week in Science, all conclude that humans carry such a high load of rare variants because the species experienced a population growth spurt that began a few millenia after the adoption of agriculture, which occurred about 10,000 years ago.
The three studies add to a growing body of knowledge that has profound implications for researchers investigating the genetic roots of disease.

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
