Fast Food Chicken Isn’t 100% Chicken (Or Even Close), Investigation Finds

Choosing grilled chicken at a fast food joint isn’t the health-conscious choice you might think. For one thing, that piece of chicken doesn’t contain only chicken, as a CBC Marketplace investigation recently found.

The Canadian TV series sent samples of chicken from five different restaurants to a university lab in Ontario for testing, finding that all of them contained significantly less protein than you’d get in a home-cooked piece of poultry.

A piece of unseasoned chicken you buy at the store should be comprised of 100 percent chicken DNA, but tests of grilled chicken from McDonald’s, Wendy’s, A&W’s, Tim Horton’s, and Subway showed much lower levels of bird DNA. Seasoning or marinating would reduce the percentage of chicken DNA in a piece of meat, but Subway, in particular, had a particularly alarming lack of chicken in its chicken.

While all the other restaurants had average values of more than 80 percent chicken DNA, Subway’s samples showed so little chicken DNA that the researchers felt compelled to go get more samples and test them again. The oven-roasted chicken used in Subway’s sandwiches…

Microbes survived inside giant cave crystals for up to 50,000 years

IN DEEP

BOSTON — Microbes found stowed inside giant crystals in caves in Chihuahua, Mexico, may have survived there for tens of thousands of years. The microorganisms, which appear to be vastly different from nearly all life-forms found on Earth, offer a good indication of how resilient life can be in extremely harsh environments, including those found on other planets.

“These organisms are so extraordinary,” astrobiologist Penelope Boston said February 17 during a news conference at the annual meeting of the American Association for the Advancement of Science. They are not close to any known genus scientists have been able to identify, said Boston, director of the NASA Astrobiology Institute in Moffett Field, Calif. Their closest relatives live in caves halfway around the world or in volcanic soils or thrive on compounds such as toluene.

For eight years, Boston and her colleagues have been studying microbes deep inside the Naica lead, silver and zinc mine. Some microorganisms were discovered trapped in fluid pockets inside massive crystals of calcium sulfate. Analysis suggests that the microbes may have been tucked away in these tiny time capsules for…
