New type of nerve cell discovered in the retina

Scientists have discovered a new type of nerve cell, or neuron, in the retina. In the central nervous system a complex circuitry of neurons communicate with each other to relay sensory and motor information; so-called interneurons serve as intermediari…

Mammals’ noses come from reptiles’ jaws

New examinations of skeletons and animal embryos have allowed researchers to discover how mammals developed protruding, flexible noses. This study contributes to uncovering the origin of mammals’ strong sense of smell and creates the potential for new …

Trapping spins with sound

Color centers are lattice defects in crystals that can capture one or more additional electrons. The spin of these electrons is very sensitive to external electric and magnetic fields — and to sound. Researchers are now reporting the selective manipul…

Spiders’ web secrets unraveled

Researchers discovered precisely how spiders build webs by using night vision and artificial intelligence to track and record every movement of all eight legs as spiders worked in the dark. Their creation of a web-building playbook or algorithm brings …
