Genomic Recycling: Ancestral Genes Take On New Roles

Weizmann Institute of Science

Dr. Igor Ulitsky has found that ancient genes that lost their ability to make proteins were “recycled,” surviving across millennia – and species – by evolving to produce a type of RNA that regulates major biological processes. His findings could lead to treatments for a number of genetic diseases.

When Ancient Fossil DNA Isn’t Available, Ancient Glycans May Help Trace Human Evolution

University of California San Diego Health

Researchers at University of California San Diego School of Medicine and collaborators discovered a new kind of glycan (sugar chain) that survives even in a 4 million-year-old animal fossil from Kenya, under conditions where ancient DNA does not. While ancient hominin fossils are not yet available for glycan analysis, this proof-of-concept study, published September 11 in Proceedings of the National Academy of Sciences, sets the stage for unprecedented explorations of human origins and diet.
