Survey Finds Microplastics in the Guts of All Seven Sea Turtle Species

Plastic is all around us—in our landfills, in our oceans, and even in the bellies of some of Earth's most vulnerable creatures. For a new paper in the journal Global Change Biology, researchers checked the guts of 102 deceased sea turtles, some of which belong to critically endangered species, and found that all of them tested positive for microplastics.

For the study, UK-based researchers from the University of Exeter, Plymouth Marine Laboratory, and Greenpeace Research Laboratories studied turtles that had died after being stranded or accidentally caught by commercial fishing operations. All seven marine turtle species were tested, including the endangered green turtle and the critically endangered hawksbill and Kemp's ridley turtles.

The specimens were found off the coasts of North Carolina in the Atlantic Ocean, northern Cyprus in the Mediterranean Sea, and Queensland, Australia in the Pacific Ocean. Necropsies revealed plastic particles under 5mm in length, while microplastic fibers were one of the most common contaminants detected in their guts. These can come from a variety of sources, including clothing, tires, cigarette filters, ropes, and fishing nets. More than 800 synthetic particles were found in the turtles. Only one section of the gut was tested in each animal, so the actual number is likely 20 times higher, according to a University of Exeter statement.

A 2015 study, also in Global Change Biology, estimated that 52 percent of all sea turtles may have ingested microplastics.

"From our work over the years, we have found microplastic in nearly all the species of marine animals we have looked at, from tiny zooplankton at the base of the marine food web to fish larvae, dolphins, and now turtles," Dr. Penelope Lindeque, of the Plymouth Marine Laboratory, said in the statement. "This study provides more evidence that we all need to help reduce the amount of plastic waste released to our seas and maintain clean, healthy, and productive oceans for future generations."

The consequences of ingesting microplastics—via contaminated water or by eating other fish or plants—isn't currently known. The particles are small enough to pass through the gut without causing any blockages, unlike larger plastics which can—and do—wreak havoc on marine life. While the authors concluded that microplastics, at their current levels, post less of a threat than fisheries bycatch and entanglements in fishing gear, they said further studies should be conducted to determine the actual risks.

"They may possibly carry contaminants, bacteria, or viruses, or they may affect the turtle at a cellular or subcellular level," lead author Dr. Emily Duncan of the University of Exeter said. "This requires further investigation."

Kodak’s New Cameras Don't Just Take Photos—They Also Print Them

Snapping a photo and immediately sharing it on social media is definitely convenient, but there’s still something so satisfying about having the printed photo—like you’re actually holding the memory in your hands. Kodak’s new STEP cameras now offer the best of both worlds.

As its name implies, the Kodak STEP Instant Print Digital Camera, available for $70 on Amazon, lets you take a picture and print it out on that very same device. Not only do you get to skip the irksome process of uploading photos to your computer and printing them on your bulky, non-portable printer (or worse yet, having to wait for your local pharmacy to print them for you), but you never need to bother with ink cartridges or toner, either. The Kodak STEP comes with special 2-inch-by-3-inch printing paper inlaid with color crystals that bring your image to life. There’s also an adhesive layer on the back, so you can easily stick your photos to laptop covers, scrapbooks, or whatever else could use a little adornment.

For those of you who want to give your photos some added flair, you might like the Kodak STEP Touch, available for $130 from Amazon. It’s similar to the regular Kodak STEP, but the LCD touch screen allows you to edit your photos before you print them; you can also shoot short videos and even share your content straight to social media.

If you want to print photos from your smartphone gallery, there's the Kodak STEP Instant Mobile Photo Printer. This portable $80 printer connects to any iOS or Android device with Bluetooth capabilities and can print whatever photos you send to it.

The Kodak STEP Instant Mobile Photo Printer connects to an app that allows you to add filters and other effects to your photos. Kodak

All three Kodak STEP devices come with some of that magical printer paper, but you can order additional refills, too—a 20-sheet set costs $8 on Amazon.

The Reason Dogs Are Terrified of Thunderstorms—And How You Can Help

Deafening thunder can be a little scary even for a full-grown human who knows it’s harmless, so your dog’s terror is understandable. But why exactly do thunderstorms send so many of our pawed pals into a tailspin?

Many dogs are distressed by unexpected loud noises—a condition known as noise aversion, or noise phobia in more severe cases—and sudden thunderclaps fall into that category. What separates a wailing siren or fireworks show from a thunderstorm in a dog's mind, however, is that dogs may actually realize a thunderstorm is coming.

As National Geographic explains, not only can dogs easily see when the sky gets dark and feel when the wind picks up, but they can also perceive the shift in barometric pressure that occurs before a storm. The anxiety of knowing loud noise is on its way may upset your dog as much as the noise itself.

Static electricity could also add to this anxiety, especially for dogs with long and/or thick hair. Tufts University veterinary behaviorist Nicholas Dodman, who also co-founded the Center for Canine Behavior Studies, told National Geographic that a static shock when brushing up against metal may heighten your dog’s agitation during a storm.

It’s difficult to nail down why each dog despises thunderstorms. As Purina points out, one could simply be thrown off by a break from routine, while another may be most troubled by the lightning. In any case, there are ways to help calm your stressed pet.

If your dog’s favorite spot during a storm is in the bathroom, they could be trying to stay near smooth, static-less surfaces for fear of getting shocked. Suiting them up in an anti-static jacket or petting them down with anti-static dryer sheets may help.

You can also make a safe haven for your pup where they’ll be oblivious to signs of a storm. Purina behavior research scientist Ragen T.S. McGowan suggests draping a blanket over their crate, which can help muffle noise. For dogs that don’t use (or like) crates, a cozy room with drawn blinds and a white noise machine can work instead.

Consulting your veterinarian is a good idea, too; if your dog’s thunderstorm-related stress is really causing issues, an anti-anxiety prescription could be the best option.
