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 
 Question:In addition to the effect on estrogen, the study also found both _ and BPS affected the thyroid hormone system.

The former neighborhood watchman never denied fatally shooting the unarmed teen, but he said he did so because he feared for his life. The intensely watched murder trial inspired passionate debate about race relations in America, gun laws, profiling and self-defense, and a good deal more. Here's where some of the key players are one year after the verdict. George Zimmerman Zimmerman has popped up a few times post-verdict.

His wife, Shellie, filed for divorce in September, citing irreconcilable differences -- and in November, Zimmerman was arrested and charged with felony aggravated assault for a domestic dispute with his girlfriend.

Q: (CNN) Sen. Jeff Sessions, Donald Trump's pick to be United States attorney general, launched a public campaign as Alabama attorney general in 1996 to prevent a gay rights group from holding a conference at the University of Alabama, according to a KFile review of contemporaneous press accounts and legal filings. Sessions's record in public office is coming under increased scrutiny now that he has been selected as Trump's attorney general. He has been a staunch opponent of the LGBT rights movement. He dubbed the Supreme Court's 2015 decision legalizing gay marriage an "effort to secularize, by force and intimidation." And in 2000 and 2009 he voted against measures expanding hate crime legislation to include sexual orientation. He's also co-sponsor, along with other prominent Republicans, of The First Amendment Defense Act, a bill opponents have dubbed "a right to discriminate." President-Elect Donald Trump has vowed he'd sign the measure.Sessions launched a public campaign as Alabama attorney general to prevent an LGBT conference from being held at a public university.Donald Trump has tapped Sessions to be United States attorney general.
