Size does indeed matter, even for avoiding extinction, but not in the way many scientists have long suspected. A new study of amphibians argues that growing smaller to take up less resources won't always help a species avoid extinction in the face of a shrinking habitat, climate change, and disease. Instead, it is argued that dimorphism - where males and females are different sizes - give a species a better shot.
It may be a little odd sounding, but tuna are very cold hearted creatures. No, they aren't unnecessarily cruel or stoic in life. Instead, they just can literally have cold hearts, with the organ somehow able to keep functioning even when deep-diving chills it to temperatures that would stop a human heart. Now researcher think they know how the fish is capable of this amazing feat.
A new study has revealed that more and more specialized flowering plants may wind up missing out on pollinators as the spring season grows warmer for many parts of the world. As net temperatures continue to climb, researchers have found that bees are waking from their wintering earlier, disrupting a synchronized bloom that some flowers had painstakingly adapted for.
