PROBLEM: (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.

SOLUTION: BPA

PROBLEM: Carrying heavy items to his car and pushing a wheelchair, terror preacher Hani Al-Sibai does not seem to have severe mobility problems.

PROBLEM: The Army has the Green Berets, while the Navy is known for the SEALs. Now, an elite branch of the U.S. Marine Corps will officially be known as Raiders. The Marines will rename several special operations units as Marine Raiders at a ceremony Friday, resurrecting a moniker made famous by World War II units that carried out risky amphibious and guerrilla operations. The exploits of the original Marine Raiders — who pioneered tactics used by present-day special forces — were captured in books and movies including 'Gung Ho!' in 1943 and 'Marine Raiders' in 1944. 'Whereas most people in the American public probably wouldn't have been able to tell you what MARSOC stood for, "Raider" will jump off the page,' said Ben Connable, a military and intelligence analyst at the nonprofit research agency RAND Corporation.An elite branch of the U.S. Marine Corps will officially be known as RaidersThe Marines will rename several special operations units as Marine Raiders at a ceremony FridayThey are resurrecting a moniker made famous by World War II units that carried out risky amphibious and guerrilla operationsThe exploits of the original Marine Raiders were captured in books and movies including 'Gung Ho!' in 1943 and 'Marine Raiders' in 1944The name will give a unique identity to the Marines' branch of U.S. Special Operations Command
