A new study has created pig embryos with some added — very little for now — human parts. But some people worry about blurring the lines between humans and animals

An international stem cell research team announced the creation of the first human–pig embryos on Thursday, opening a new frontier in research into “chimera” mashups of human and animal tissues.

The study, conducted by a team at the Salk Institute in California in collaboration with researchers in Spain, is one of several early attempts to grow human tissue inside animals to produce organs needed for transplants such as hearts and kidneys.

The Goldilocks Effect in Aging Research

by Salk Institute, Neuroscience News

Ever since researchers connected the shortening of telomeres–the protective structures on the ends of chromosomes–to aging and disease, the race has been on to understand the factors that govern telomere length. Now, scientists at the Salk Institute have found that a balance of elongation and trimming in stem cells results in telomeres that are, as Goldilocks would say, not too short and not too long, but just right.
