New Species of Beetle Discovered in Dinosaur Ancestor’s 230 Million-Year-Old Poop
The tiny beetle Triamyxa coprolithica is the first-ever insect to be described from fossil feces. The animal the researchers have to thank for the excellent…
Purging Bad Mutations: Males Help Keep Populations Genetically Healthy
A few males are enough to fertilize all the females. The number of males, therefore, has little bearing on a population’s growth. However, they are…
Earth’s Mantle Provides New Clues To Explain Indonesia’s Explosive Volcanoes
Indonesia’s volcanoes are among the world’s most dangerous. Why? Through chemical analyses of tiny minerals in lava from Bali and Java, researchers from Uppsala University…
