Ancient DNA reveals new branches of the Denisovan family tree

It's widely accepted that anatomically modern humans interbred with their close relatives, the Neanderthals and Denisovans, as they dispersed out of Africa. But a study examining DNA fragments passed down from these ancient ...

International team decodes the durum wheat genome

An international consortium has sequenced the entire genome of durum wheat—the source of semolina for pasta, a food staple for the world's population, according to an article published today in Nature Genetics.

Keeping genetic engineering localized

Genetic engineering tools that spread genes within a target species have the potential to humanely control harmful pests as well as eradicate parasitic diseases such as malaria.

Genes that evolve from scratch expand protein diversity

One of the most important questions in biology is how rapidly new proteins evolve in organisms. Proteins are the building blocks that carry out the basic functions of life. As the genes that produce them change, the proteins ...

Genome structure of malaria parasites linked to virulence

An international research team led by scientists at the University of California, Riverside, and the La Jolla Institute for Immunology has found that malaria parasite genomes are shaped by parasite-specific gene families, ...
