Scientists show how two different species of Australian fairy-wrens not only recognize individual birds from other species, but also form long-term partnerships that help them forage and defend their shared space as a group.
A study of two closely related frog species reveals a population of neurons that give rise to the unique mating calls of each species. The findings suggest that changes in the properties of these cells over the course of evolution may have shaped vocal patterns in vertebrates including bats and primates.
Molecules that are involved in photosynthesis exhibit the same quantum effects as non-living matter, concludes an international team of scientists. This is the first time that quantum mechanical behavior was proven to exist in biological systems that are involved in photosynthesis. The interpretation of these quantum effects in photosynthesis may help in the development of nature-inspired light-harvesting devices.
