"True hybrid" mice might reveal how new species emerge
Forty years ago, a postdoctoral researcher named James McGrath who would go on to spend more than three decades as a clinical geneticist and research scientist at Yale, made a discovery that advanced scientists' understanding of gene control and the.....»»
"Paleo-robots" provide an experimental approach for understanding how fish started to walk on land
The transition from water to land is one of the most significant events in the history of life on Earth. Now, a team of roboticists, paleontologists and biologists is using robots to study how the ancestors of modern land animals transitioned from sw.....»»
Insect and spider biodiversity increases organic nutrient availability across ecosystems, large-scale study shows
Insects and spiders are important elements in the food webs of aquatic and terrestrial ecosystems. With declines in their biodiversity, the food supply for birds, fish, reptiles, amphibians and small mammals is not only becoming scarcer, but also poo.....»»
