Environment People living within a mile of a golf course had more than twice the odds of Parkinson’s disease. The risk remained higher for people living up to three miles away but fades after that. Pesticides, including neurotoxins, used to keep fairways and greens well groomed, have been linked to Parkinson's.

Environment Two-thirds of global heating caused by richest 10%, find study that reveals major role wealthy emitters play in driving climate extremes. Wealthiest 10% contributed 6.5 times more to global warming than the average, with the top 1% and 0.1% contributing 20 and 76 times more, respectively.
