Scientists released an army of fake insect larvae to investigate how predators attack their prey—the tropics officially win as the world’s “hardest place to survive.”
The list of animals that use tools keeps growing, from chimps to birds and even octopuses. So is it time that we abandoned "tool use" as a measure of intelligence among species?
Scientists constructed an artificial Milky Way, using LEDs, to test the beetles’ abilities to navigate. It turned out that the beetles rely on the contrasting brightness between different parts of the Milky Way to work out which way to go.
Scientists have recorded conversations between mother humpback whales and their calves for the first time. The recording shows how young whales “whisper” to their mothers so that potential predators cannot hear them.
Scientists have discovered the fossilised remains of 1.6 billion year-old red algae from India. Advanced multicellular life began much earlier that previously thought and the timing of the tree of life should be revised, they say.
