When it comes to body size, larger species usually win out over smaller ones. Now one biologist has found that sometimes small species of birds can dominate larger species during aggressive interactions, especially when they interact with distantly related species.
As our climate changes, forest ecosystems around the world are also changing. Now, 107 collaborators have taken a look at trees around the world in order to examine how 59 forests from 24 countries are changing.
During division, cells copy and split DNA while breaking safely into two viable daughter cells, a process called cytokinesis. Yet the molecular basis of how plant cells accomplish this feat without mistakes has been unknown--until now.
Grassland prairies may be under a new and unusual threat. It's not from animals; it's not from humans. Instead, the threat comes from trees and shrubs.
A new crew including members from the United States and Russia is on its way to the International Space Station after launching the Soyuz capsule September 25.
Scientists have taken a look at the most comprehensive family tree of meat-eating dinosaurs to date. Now, they're using this family tree to uncover key details of how birds evolved from these prehistoric terrors, examining feathers, wings and wishbones.
Global sea level rise isn't just something we're dealing with in the present day. Scientists have now found at the end of the last five ice-ages, global sea-levels rose at rates of up to 5.5 meters per century.
The bees you see buzzing from flower to flower may not just be pollinators; they may also be doctors. Scientists have introduced a new method to turn bees into tiny insect medics in order to deliver disease control to cherry blossoms and prevent brown rot in cherries.
When did multicellular life first evolve? That's a good question, and its own which geobiologists may now have an answer to.
Scientists have discovered that insects' fear of their predators ultimately limits how fast they grow, which could be an important factor to take into account when monitoring how insects might react to climate change.
A newly unearthed armoured dinosaur from New Mexico may be closely related to the dinosaurs of Alberta, a new study has revealed.
