The human heart may start beating as early as 16 days after conception, a new study in mice suggests, a finding that may help understand and prevent heart conditions that arise as a foetus develops.
Researchers at the University of Oxford in the UK looked at the developing mouse heart and found that the muscle started to contract as soon as it formed the cardiac crescent - an early stage in heart development.

Previously, it was thought that the heart started to contract a stage later, when the heart appears as a linear tube.
