Ottawa, Canada (CNN) What's going on with Justin Trudeau? Since his surprising election last October, Trudeau has enjoyed soaring popularity as the young, hip, progressive Prime Minister of Canada. Blessed with charm, good looks, a name and a photogenic family, he has become an overnight international celebrity. Promising "sunny ways" after a decade of the divisive politics of Stephen Harper and his Conservatives, Trudeau and his Liberals have proclaimed a new tone of civility in Parliament in their seven months in office. But all that dissolved on the floor of the House of Commons Wednesday in a fracas both unseemly and unprecedented. At the center was a less saintly Trudeau: petulant, impatient and later, embarrassed and "unreservedly" apologetic.Andrew Cohen: Canadian Prime Minister involved in a parliament fracas that has some questioning his maturity for jobCohen: He apologized, but popular PM has lost his shine; has learned early lesson on governing, discipline, the scrutiny of celebrity

(CNN) Your "BPA-free" plastic product may be no safer than the product it replaced, says a new UCLA study that analyzed the impact of a common BPA alternative on zebra fish embryos. The study joins a small but growing group of similar research sounding the alarm about so called "BPA-free" alternatives. "Our findings are frightening and important," said senior author and reproductive endocrinologist Nancy Wayne. "Consider it the aquatic version of the canary in the coal mine." After decades of animal research linked BPA (Bisphenol A), a known endocrine disruptor, to problems with brain and reproductive development, early puberty and a rise in breast and prostate cancer, many manufacturers stopped using the chemical to harden plastics, replacing it with "BPA-free" alternatives. The most common replacement is BPS (Bisphenol S), said Wayne.BPA-free alternatives may be no safer than BPA, say researchersMost common alternative, BPS, linked in study to disruptions of estrogen and thyroid hormones 
 Question:In addition to the effect on estrogen, the study also found both _ and BPS affected the thyroid hormone system.

Riyadh, Saudi Arabia (CNN) Few might have expected that four months into his term President Donald Trump would find himself addressing a room of Muslim leaders after a night surrounded by dancing, drumming Saudi men. But there he was Sunday, standing at the front of a vast reception hall, declaring Islam one of the world's great religions while encouraging leaders to disavow terrorists. And there he was Saturday night, swaying to rhythmic lyrics in Arabic, only a year after deriding Islam as a religion based in hatred and vowing to bar all Muslims from entering the United States. Ensconced within the presidential bubble on his first foreign trip, Trump is regularly finding the view from inside is often far different than from out. It's a lesson most presidents learn sooner or later. For Trump, who ran as an outsider promising to explode political norms, the adjustment appears more abrupt.Trump delivered a major address to Arab leaders SundayHe used softened rhetoric compared to his campaign
