Scientists have devised a new strategy for selectively delivering genes into the mitochondria of plant cells by using a simple combination of cell-penetrating and mitochondria-targeting peptides. This work lays the groundwork for the rational design of peptide-based gene carriers with the potential to create a new field of 'mitochondria engineering', which could enable the creation of mitochondria-based plant cell factories for the creation of bio-polymers and bio-fuels.

New research shows that the genetic capacity of bacteria to make terpenes is widespread. Using a specialized technique to sift through genomic databases for a variety of bacteria, the researchers found 262 gene sequences that likely code for terpene synthases - enzymes that catalyze the production terpenes.

Read moreA clear, molecular view of how human color vision evolved
Many genetic mutations in visual pigments, spread over millions of years, were required for humans to evolve from a primitive mammal with a dim, shadowy view of the world into a greater ape able to see all the colors in a rainbow. Now, after more than two decades of painstaking research, scientists have finished a detailed and complete picture of the evolution of human color vision.
