[Q]: (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

[Q]: (CNN) There is a story, popular among British politicians and attributed to the Australian strategist Lynton Crosby, known as "The Dead Cat." A CEO is confronted with poor statistics at a board meeting, and to divert attention from this unpleasant news, he suddenly pulls out a dead cat and throws it onto the middle of the table. In the words of Boris Johnson, now the UK foreign secretary: "There is one thing that is absolutely certain about throwing a dead cat on the table -- and I don't mean that people will be outraged, alarmed, disgusted. That is true, but irrelevant. The key point... is that everyone will shout, 'Jeez, mate, there's a dead cat on the table!' In other words, they will be talking about the dead cat -- the thing you want them to talk about -- and they will not be talking about the issue that has been causing you so much grief."Kate Maltby: To distract from his negative media coverage, Trump created a Twitter storm over Mike Pence at "Hamilton"But Trump threatened freedom of expression; his tweets need a strong response from editors nationwide, writes Maltby

[Q]: The Duchess of Cambridge's decision to 'borrow' a priceless tiara belonging to the Queen Mother rather than buying a new one has confused the Chinese media, MailOnline can reveal today.
