Smaller ants devote more of their resting energy budget to their brains
The energy required for brains of different sizes to function could play a role in how different species evolved over time. While the energetic costs of brains have long been deemed important in evolution, direct measurements ...

Scientists count more than 2 million eels on one underwater mountain
Patience Seamount is an underwater mountain in Australia's Huon Marine Park off the coast of Tasmania. Every year, it is the site of an enormous gathering of basketwork eels (Diastobranchus capensis) for reasons unknown, ...
Chornobyl dog population shows genetic signatures of directional selection
The latest research on the wild population of dogs in Chornobyl reveals that the genetic differences between these dogs and other similarly isolated dog populations are likely evidence of directional selection, not mutation. ...

New tissue atlas aims to help AI understand cancer
How cells are arranged within tissue can reveal as much about disease as the cells themselves. When doctors examine a cancer tumor, for example, they don't just look at which cells are present; they also want to know how ...

Islands harbor nearly 20% of Earth's biodiversity, yet remain overlooked in conservation strategies
Although they account for just 7% of the Earth's land surface, island ecosystems harbor almost 20% of the world's biodiversity. From sea-level rise to biological invasions, islands are facing multiple pressures associated ...
