‘Material universe’ yields surprising new particle (Nature)

By Staff An international team of researchers has predicted the existence of a new type of particle called the type-II Weyl fermion in metallic materials. When subjected to a magnetic field, the materials containing the particle act as insulators for current applied in some directions and as conductors for current applied in other directions. This … Continue reading ‘Material universe’ yields surprising new particle (Nature)

Army ants’ ‘living’ bridges span collective intelligence, ‘swarm’ robotics (PNAS)

By Morgan Kelly, Office of Communications Columns of workers penetrate the forest, furiously gathering as much food and supplies as they can. They are a massive army that living things know to avoid, and that few natural obstacles can waylay. So determined are these legions that should a chasm or gap disrupt the most direct … Continue reading Army ants’ ‘living’ bridges span collective intelligence, ‘swarm’ robotics (PNAS)

Group living: For baboons intermediate size is optimal (PNAS)

By Gregory Filiano, Stony Brook University Living with others can offer tremendous benefits for social animals, including primates, but these benefits could come at a high cost. New research from a project that originated at Princeton University reveals that intermediate-sized groups provide the most benefits to wild baboons. The study, led by Catherine Markham at … Continue reading Group living: For baboons intermediate size is optimal (PNAS)
