This Special Music Helped Preemie Babies’ Brains Develop
Move over, Baby Einstein: New research from Switzerland shows that listening to soothing music in the first weeks of life helps encourage brain development in preterm babies.
For the study, the scientists recruited a harpist and a new-age musician to compose three pieces of music.
The Lowdown
Children who are born prematurely, between 24 and 32 weeks of pregnancy, are far more likely to survive today than they used to be—but because their brains are less developed at birth, they're still at high risk for learning difficulties and emotional disorders later in life.
Researchers in Geneva thought that the unfamiliar and stressful noises in neonatal intensive care units might be partially responsible. After all, a hospital ward filled with alarms, other infants crying, and adults bustling in and out is far more disruptive than the quiet in-utero environment the babies are used to. They decided to test whether listening to pleasant music could have a positive, counterbalancing effect on the babies' brain development.
Led by Dr. Petra Hüppi at the University of Geneva, the scientists recruited Swiss harpist and new-age musician Andreas Vollenweider (who has collaborated with the likes of Carly Simon, Bryan Adams, and Bobby McFerrin). Vollenweider developed three pieces of music specifically for the NICU babies, which were played for them five times per week. Each track was used for specific purposes: To help the baby wake up; to stimulate a baby who was already awake; and to help the baby fall back asleep.
When they reached an age equivalent to a full-term baby, the infants underwent an MRI. The researchers focused on connections within the salience network, which determines how relevant information is, and then processes and acts on it—crucial components of healthy social behavior and emotional regulation. The neural networks of preemies who had listened to Vollenweider's pieces were stronger than preterm babies who had not received the intervention, and were instead much more similar to full-term babies.

The first infants in the study are now 6 years old—the age when cognitive problems usually become diagnosable. Researchers plan to follow up with more cognitive and socio-emotional assessments, to determine whether the effects of the music intervention have lasted.
The first infants in the study are now 6 years old—the age when cognitive problems usually become diagnosable.
The scientists note in their paper that, while they saw strong results in the babies' primary auditory cortex and thalamus connections—suggesting that they had developed an ability to recognize and respond to familiar music—there was less reaction in the regions responsible for socioemotional processing. They hypothesize that more time spent listening to music during a NICU stay could improve those connections as well; but another study would be needed to know for sure.
Open Questions
Because this initial study had a fairly small sample size (only 20 preterm infants underwent the musical intervention, with another 19 studied as a control group), and they all listened to the same music for the same amount of time, it's still undetermined whether variations in the type and frequency of music would make a difference. Are Vollenweider's harps, bells, and punji the runaway favorite, or would other styles of music help, too? (Would "Baby Shark" help … or hurt?) There's also a chance that other types of repetitive sounds, like parents speaking or singing to their children, might have similar effects.
But the biggest question is still the one that the scientists plan to tackle next: Whether the intervention lasts as the children grow up. If it does, that's great news for any family with a preemie — and for the baby-sized headphone industry.
Edible Silverware Is the Next Big Thing in Sustainable Eating
Sure, you may bring a reusable straw when you go out to eat. But what about digesting your silverware at the restaurant? The future is already here.
Edible cutlery feels like a natural progression post-reusable straw.
Air New Zealand just added the new edible coffee cup Twiice into their in-flight service. Made from vanilla, wheat flower, sugar, egg and vanilla essence, the Twiice cups will be standard issue for the international airline.
On the ground, the new, award-winning startup IncrEDIBLESpoon has shipped more than a quarter million edible scoopers. The spoons are all-natural, vegan, and made from wheat, oat, corn, chickpea and barley.
The technological breakthrough is in creating tasty, mass-market material durable enough for delivery in an assembly line environment like airplane service, as well as stable enough to hold a hot cup of coffee or a freezing scoop of ice cream. Twiice cups can last several hours after hot coffee is added, while IncrEDIBLESpoon cutlery holds up to 45 minutes.
"We already caught the interest of a couple major ice cream chains," says Dinesh Tadepalli, co-founder of the IncrEDIBLESpoon parent company Planeteer. "If all goes well, one of them will test out our spoons at their scoop shop early this year."

Edible cutlery feels like a natural progression post-reusable straw. And more is already on the menu.
The coffee cup company Twiice is already planning on expanding. Co-founder Jamie Cashmore says other serving items are coming later this year.
IncrEDIBLESpoon is also getting into more utensils. "We plan to mass produce the complete set by year's end: Edible straws, edible forks and edible coffee stirrers," Tadepalli says.
Most notably, Twiice's partner Air New Zealand sees the coffee cup as just a start to other sustainable solutions. The airline estimates it currently serves eight million cups of coffee annually. It's even suggesting customers bring their own reusable cup to the plane – though that isn't as ergonomic nor as attractive as eating everything you are served.
Open Questions
Making everything edible has a few challenges. First is cultural acceptance: With respect to current success, changing eating habits will require going beyond eco-focused and curious eaters.
Second, it's unclear if the short-term economics will add up in favor of airline carriers and other companies. Like alternative fuel, organizations will be more likely to adopt new science when it doesn't require a retrofitting or expensive change to their current business model – even if it does create long-term benefits.
The changes will likely be lopsided, influencing cultures at different times. Airplanes are a great start, as passengers are a captive audience interested in removing waste as soon as possible.
"Imagine eating a black pepper spoon after your soup or a chocolate spoon after your ice cream?"
We can expect edible cutlery to make an easier impact with certain cultures or foods. For instance, injera, the spongy Ethiopian bread, has served as an African plate of sorts for years. It makes sense that IncrEDIBLESpoon's four flavors, Salt, Masala, Spinach and Root, all fit in another bread-as-plate friendly culture: Indian.
Coffee and desserts sound like a good bet for now, though, especially for foodies. "People are curious to try edible spoons as they never heard or experienced them before," Tadepalli says. "Imagine eating a black pepper spoon after your soup or a chocolate spoon after your ice cream?"
The Secrets of a Long Life from the U.S.’s Top Longevity Hot Spot
People are living longer in the world's richest countries, according to a recent Pew Report. Certain areas, in particular, have drawn the attention of researchers who study longevity because in those places, living to 100 is not unusual.
"If you want to live longer, shape your environment."
At 8000 feet up, Summit County, Colorado is a longevity hotspot. Surrounded by mountains that soar to more than 14,000 feet, the population of nearly 31,000 brags the highest expected lifespan in the United States, at 86.83 years. For comparison, the average life expectancy in the U.S. is 78.6 years.
So, what is it about living in Summit County that has brought about this high honor?
Despite popular belief, it's not about genes. Only about "20-30 percent of longevity can be predicted by genetics," longevity researcher Howard S. Friedman wrote in an email exchange. Friedman, a professor at the University of California at Riverside, co-authored a book about a famous study that followed participants for eight decades to learn what traits and factors contribute to a long life.
"About half is behavioral (including environmental)," Friedman says. "The rest is random (chance)." His longevity research is based on work that began in 1921 by Stanford University psychologist Lewis Terman. To discern the keys to longevity, Friedman and colleagues spent 20 years looking back at the lives led by the 1500 "gifted" 11-year old boys and girls who were born in 1910 and participated in Terman's study.
"We found that ambition, perseverance, and high motivation … predicted not only success but also longevity: Stressful job and hard work, long life!" Friedman says.
Longevity expert Dan Buettner agrees that an individual's environment is key. Buettner studies what he calls Blue Zones, where people "naturally live longer." But, unlike the five Blue Zones in the world -- Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; Ikaria, Greece; and Loma Linda, California — the majority of the Summit County population chose to move to the mountain towns that make up the region. Because Buettner believes that people can be taught to live longer, he sees Summit County as an instructive locale.
Like the Blue Zones, people in Summit County "do not pursue healthy lifestyles; [rather] it ensues," he says. "Blue Zones have the benefit of traditional patterns of eating and traditional rhythms of life. So they tend to be places where people walk to work, to a friend's house … [and] Blue Zone people eat the right food -- not because they have better individual responsibility or discipline; they simply live in an environment where beans, greens, nuts and grains are cheapest and most accessible."
"If you want to live longer," Buettner says, "shape your environment."
But an individual's environment can be affected by a number of factors, including socioeconomics, race, quality of and access to health care, as well as behavioral and metabolic risks. While the residents of Summit County smoke less and exercise more than those in regions with shorter life spans, they also have higher incomes and levels of education and lower unemployment.
"The healthiest individuals in The Longevity Project…lived meaningful, committed lives. They worked hard and played hard."
Gloria Breigenzer moved to Summit County 20 years ago with her husband. "We wanted to ski and ride horses up in the mountains," says Breigenzer. The 75-year-old still works part time as a hair dresser, goes to the gym every day, lifts weights and does yoga.
"I don't know why people don't want to get up and go out and work out and do stuff. I do," says the grandmother, who also exercises her rescue horse five days a week and for the past 15 years has done swing, country two step, and jazz dance in a group with her 77-year-old husband. She's also taking kiteboarding lessons and for the past two years has spent every afternoon studying Spanish.
Pete and Judy Rubin, both 65, retired to Summit County nearly two years ago from Cleveland. In Colorado, "socializing doesn't revolve around food," says Pete. "In Cleveland it always did…[Being outside] in summer or in winter is just easy. Skiing, on a bike, taking a hike, mowing the lawn, looking at a mountain instead of having someone else do it."
The Summit County approach resonates for researcher Friedman, who says that it's the "constellations of habits and patterns of living," that stood out most to him in his study. "Throw away your lists...The healthiest individuals in The Longevity Project…lived meaningful, committed lives. They worked hard and played hard. They were very persistent and responsible, and they were dedicated to things and people beyond themselves."
The following are some of the common denominators found in populations that live longer, including those who live in Summit County:
Plant-based diet: "Eat meat, no more than 5 times a month … [and] 95 percent of all the calories you take in should be whole plant-based foods," says Buettner.
Know your purpose: Buettner found that having and understanding your sense of purpose is worth up to seven years of extra life expectancy.
Have friendships: "You should have three to five friends who are healthy themselves who you can call on a bad day and they'll care," says Buettner.
Be on the move: Populations in zones where there is higher longevity "move naturally" as part of their day. It's not about diets. "No diet in the history of the world has worked for more than 5 percent of people after two years," says Buettner.
Relieve stress: "You should have some daily practices that help you downshift," says Buettner. It "could be taking naps, or meditation practice, or a habit of praying or a habit of doing happy hours."
Employ a family first rule: "Successful centenarians put their families first," explains Buettner. "And that means keeping your aging parents nearby, being seriously invested in your partner and if you have kids, you make them a priority."
It's these "key patterns of living [that] tend to make you both healthier and happier," says Friedman. "And health and happiness often then mutually reinforce each other."
