Women who smoked the most years, consumed the highest number of cigarettes per day and had a specific form of NAT2 were at significantly increased risk of breast cancer.

Lloyd quotes Kurzweil as saying he is “confident that we are not that far away from a tipping point where energy from solar will be [economically] competitive with fossil fuels.”
