A brand new fish may be coming soon to a plate near you. The AquaBounty AquAdvantage salmon, a genetically engineered species of fish, is the first engineered animal approved for human consumption. The new fish’s genetic code comes from three fish: base DNA from an Atlantic salmon; a growth gene from a Pacific Chinook salmon; and a promoter (a sort of genetic activation switch), from the eel-shaped ocean pout.
Feeling queasy about eating a frankenfish? AquaBounty says their salmon is good for the environment. Whole Foods, Trader Joe’s, Safeway, Kroger’s, Red Lobster, along with other purveyors of sea food say they have no intention of offering AquAdvantage salmon to customers.
One thing can be said in the engineered salmon’s favor – at least you’ll know what you’re eating. A recent report by nonprofit organization Oceana found that, in eighty-two salmon samples taken from restaurants and grocery stores, sixty-nine per cent of the sampled “wild caught Pacific Salmon” was actually farmed Atlantic salmon.

Dental School Art Skills
Hoang Tran spent three years in dental school before he decided that dentistry wasn’t the career for him. Now he uses the dental skills that he learned to carve intricate portraits of pop culture celebrities on crayons.
“I withdrew (from dental school) to pursue something more creative,” he told Instagram. “I had seen someone else’s crayon carvings years before, and they stuck in my mind. Because we’d done something similar in dental school — we carved teeth from wax — I knew I had the skills to try [it].”
Tran has had his art exhibited and sells his work on Etsy, priced at $30 to $60.
Now We Know
Some people like chewing ice, others get a weird joy from cracking their knuckles. And finally, researchers have found out what makes that “cracking” sound: tiny gas bubbles crashing into each other between the bones of the flexed joints.
Researchers from the University of California, Davis used ultrasound imaging to track what happens when we crack our knuckles. During the process they also discovered that flash of bright light occurs about 10 milliseconds after the cracking sound is heard. The research team described it as “fireworks exploding in the flexed joints”
The team also found that for people without joint problems, knuckle cracking doesn’t seem to injure the joints.
The research was presented at the Radiological Society of North America’s annual meeting in Chicago prior to its publication in a peer-reviewed journal.
Goodbye Soda, Hello Healthier Smile
Restaurant chains Applebee’s and IHOP are removing soda from children’s menus nationwide.
Soft drinks will still be available; they just won’t be featured on the menus for the chains youngest customers. Kids’ choices will include milk, chocolate milk, hot chocolate and, beginning next spring, juice, in the IHOP’s children’s menu.
Chocolate drinks (and fast food in general) aren’t the best choice for dental health either, but it’s a small step in the right direction. McDonald’s, Burger King, Wendy’s,Dairy Queen, Chipotle, Panera and Subway have or are in the process of reevaluating their kids’ menus with an eye towards providing healthier choices.
