Researchers led by electrical engineers at the University of California San Diego have developed a better way to perform the comparative analysis of entire genomes. This approach can be used to study relationships between different species across geological time scales. This new approach is poised to unlock discoveries regarding how evolution has shaped present-day genomes and also how the tree of life is organized. The new method, named CASTER, is described in a paper published in Science on 23 January 2025.
There’s a downside to being a powerful alpha male -- at least if you’re a baboon. Studies show that despite their high rank, the No. 1 males in baboon society are also some of the most stressed out, as measured by their high levels of glucocorticoid hormones. But new research reveals it’s not the time they spend fighting with other males that raises their stress. Instead, it’s the effort they put into their mates.
