Tattoos have been around for thousands of years, primarily as an artform. But what if they had a purpose, beyond just aesthetics? “I think that we can upgrade tattoo inks to give people new abilities,” says Carson Bruns, a mechanical engineer professor at the University of Colorado. Bruns is also a tattoo aficionado. "I got my first tattoo when I was 19 years old, and I’ve been addicted to tattoos ever since," Bruns says.He spends his days in a lab, working to bring an ancient artform into the 21st Century. "My idea is that, by adding new function, new properties to the tattoo inks, that tattoos could potentially be used for more than just art," he says. Bruns is focused on a specific type of tattoo ink, one that would embed tiny microcapsules filled with certain material underneath the skin. One of his most promising developments would fill those capsules with UV dye. It’d essentially be a tattoo that tells you when you need to apply sunscreen. "So our tattoo, anytime you can see it, anytime it's visible to you, that's a sign your skin is dangerously exposed to UV light and its increasing your risk to skin cancer,” Bruns explains. Other types of inks would be heat-sensitive, like the squares he's tested on his own skin. Those would only appear when your body reached a certain temperature. "A tattooable thermometer, made of these heat sensitive tattoo inks could be a way to make it more accessible for people to read their body temp and check up on their own health," he says. Bruns says the possibilities are endless. "I like to joke tattoos can give you superpowers,” he says. “They can give our skin new properties we don't currently have."Bruns hopes that one day, we might even be able to come up with tattoo inks that could conduct electricity or even tell us our blood sugar or blood alcohol levels. 1843

Scientists are working to eliminate a type of heart disease in dogs using gene therapy. They're zoning in on a heart condition called mitral valve disease that’s common in 6% of dogs. Scientists are using Cavalier King Charles spaniels for the research. They tend to develop it at a younger age. Scientists at Tufts University have already tested gene therapy in mice. A virus is injected into them to deliver DNA to cells which causes them to create a protein. What it essentially does is stops the heart valve from getting thicker, stopping the valve from leaking. Researchers are now moving on to testing this in dogs. But they think the treatment could go beyond just canines. “Many of the dog diseases are naturally occurring and really great models for human disease,” says Dr. Vicky Yang, a veterinary cardiologist and research assistant professor at Cummings School of Veterinary Medicine at Tufts University. “And I can see this, if it becomes successful in dogs, potentially going into thinking about treatment for humans for mitral valve disease.”The biotech company behind the treatment agrees. It says it could also expand beyond heart problems. “I think a larger question, though, is if we are able to prove this thesis of treating aging, making the animal generally healthier, could also treat heart failure, what other diseases could we treat in dogs?” says Daniel Oliver, the CEO of Rejuvenate Bio. “And could we progress this treatment onto past dogs and other animals and possibly humans?” The gene therapy would only be used for dogs just starting to experience heart problems.Researchers still need to make sure the gene therapy is safe for all breeds before they make it available to the public. 1730

WINNETKA, Ill. – Nearly 27 million American adults have low vision or blindness. As baby boomers age, experts expect a major one in three will experience vision loss, a condition linked to depression. It’s a tough transition leaving many in despair. In recent years, Illinois resident Richard Englund’s vision began fading. “It's a whole new world. You know that you're dealing with something you've never dealt with before,” said Englund. Diagnosed with macular degeneration at 47, the world he knew lost focus. He is now legally blind. “The worst thing that you've finally come to terms with is you can't drive anymore,” said Englund. For Angie, a retired nurse, a third failed corneal transplant meant losing her sight but not her sense of humor. “Not being able to see faces. I mean right now all you guys look like Brad Pitt,” said Angie. But it took time for her to come to terms with it. “I felt like I was walking dead,” said Angie. “Somebody hit me in the stomach and it just was wrong.” Loss of mobility and independence is difficult and statistically, people with visual impairment or blindness have a 200 percent increase in the risk of clinical depression. As baby boomers age, the number of Americans with low vision is expected to skyrocket from 2.9 million in 2010 to 5 million in 2030. The key, say public health officials, is to reach out for help early. For the last century, Hadley, a non-profit organization has assisted with the scary transition of losing sight. “We basically teach people how to continue to live their lives,” said Julie Tye, Hadley’s executive director. Hadley is providing online resources, support and in-person consultation. All of it is free of cost. “Maybe it's something as simple as contrast, maybe it's something as simple as using their smartphone to magnify what they're reading,” said Tye. Englund says relearning independence is tough at any age, but not impossible. “I am not going to let the fact that I can't see keep me from doing anything. I can do anything as long as I put my mind to it,” he said. Angie insists it’s just another phase of life. “You realize that you go on, you know, it's another journey you're on. You're going to do better, because you have to.” 2243
