Oriole hybridization is a dead end: study

A half-century of controversy over two popular bird species may have finally come to an end. In one corner: the Bullock's Oriole, found in the western half of North America. In the other corner: the Baltimore Oriole, breeding ...

Software package helps make sense of complex tree data

Most plant features arise from complex interactions of genes, proteins and metabolites. The identification and analysis of these genetic traits is very challenging, especially when the sequenced genomes are fragmented. In ...

Genome editing strategy could improve rice, other crops

Scientists at UC Davis have used CRISPR technology to genetically engineer rice with high levels of beta-carotene, the precursor of vitamin A. The technique they used provides a promising strategy for genetically improving ...

Family matters for world's second biggest fish

The world's second biggest fish—the basking shark—prefers to travel with family to familiar feeding sites, according to a new study led by the University of Aberdeen.

Simplifying simple sequence repeats

Simple sequence repeats (SSRs) are regions of DNA with high diversity, and they have long been a mainstay for botanists examining the genetic structure of plant populations. However, as the cost of sequencing DNA continues ...

Scientists devise 'lifespan clock'

An Australian research team say they have come up with a "lifespan clock" which provides accurate maximum age estimates for vertebrates, a key variable in the study of both living and extinct animals.
