Researchers say the cause of severe morning sickness is genetic - not in the mind. The condition affects 1 in 100 pregnant women, including the Duchess of Cambridge. In its most serious cases, sufferers report being sick up to fifty times a day. Up until now, it's been unclear as to what causes it, but scientists from the University of California think they've made a breakthrough. Lead researcher Marlena Fejzo spoke to the 大象传媒's Alex Ritson.
