Embryo research provides a solid basis for developing better infertility treatments

A research group focused on embryos has begun its work in Finland, comprehensively surveying for the first time the short RNA molecules that regulate genome function during embryonic development. Information gained from human ova and embryos helps to understand problems occurring during pregnancy and develop increasingly effective infertility treatments. Not much is known about early […]

From imaging neurons to measuring their true activity

When neurons communicate with each another, they transmit—or “fire”—small electrical impulses called action potentials or spikes. These action potentials are the fundamental units of information processing in the brain. Today, neuronal activity is often measured by calcium imaging, which uses advanced microscopy to detect changes in the fluorescence of a calcium indicator inside neurons. This […]
