Question: (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.

Question: A series of chilling text messages that a suicidal father sent to his increasingly panicked ex-girlfriend in the final moments before he allegedly threw their baby son to his death off a bridge has emerged. As he stood on Connecticut's Arrigoni Bridge with his seven-month-old son Aaden on Sunday night, Tony Moreno, 22, exchanged dozens of texts with his former partner, 19-year-old Adrianne Oyola. In separate messages, he told her: 'Enjoy your new life without us', 'There is no more days [sic]' and 'You're not a parent anymore' - prompting Oyola to frantically ask about her son's whereabouts. Moreno then wrote: 'He's dead', followed by 'And soon I will be too.'

Question: (CNN) Hillary Clinton has advantages heading into the final stretch of the campaign that any presidential candidate would envy: a fleet of popular surrogates, a mountain of cash and an opponent who is often sidetracked by self-inflicted wounds. Yet the Democratic nominee enters this home stretch in a dead heat against Donald Trump, according to a CNN/ORC poll released Tuesday. The close contest heading into the fall underscores Clinton's vulnerabilities on trust and honesty -- and her need to summon a relentless and efficient ground game, even if many of her voters are fueled more by revulsion toward Trump than excitement about her.The 2016 race remains within the margin of error in the latest CNN/ORC pollClinton has started to be more aggressive against Donald Trump this week
