A genome-wide association study of metabolic biomarkers in 136,000 participants discovered more than 400 independent genomic regions affecting metabolism. The study also highlighted the importance of participant characteristics, such as fasting status, that can substantially affect the genetic associations.

Clarifying how genome duplication and triplication events shaped early vertebrate genomes has presented a challenge in evolutionary biology. The genome of the jawless hagfish provides a missing piece of this puzzle.

By using volunteers to map roads in forests across Borneo, Sumatra and New Guinea, an innovative study shows that existing maps of the Asia-Pacific region are rife with errors. It also reveals that unmapped roads are extremely common — up to seven times more abundant than mapped ones. Such ‘ghost roads’ are promoting illegal logging, mining, wildlife poaching and deforestation in some of the world’s biologically richest ecosystems.

The development of high-performance organic LEDs and other devices that emit near-infrared light has been hindered by seemingly fundamental features of the light-emitting molecules. A potential solution has been identified.
