av Friendship Is a Lifesaver - Issue 84: Outbreak By nautil.us Published On :: Thu, 16 Apr 2020 01:00:00 +0000 My mother-in-law, Carol, lives alone. It was her 75th birthday the other day. Normally, I send flowers. Normally, she spends some part of the day with the family members who live nearby and not across the country as my husband, Mark, and I do. And normally, she makes plans to celebrate with a friend. But these are not normal times. I was worried about sending a flower delivery person. Social distancing means no visiting with friends or family, no matter how close they are. So, my sister-in-law dropped off a gift and Mark and I sang “Happy Birthday” down the phone line with our kids. But I could hear the loneliness in Carol’s voice.This was hardly the worst thing anyone experienced in America on that particular April day. We are fortunate that Carol is healthy and safe. But it upset me anyway. People over 60 are more vulnerable to COVID-19 than anyone else. They are also vulnerable to loneliness, especially when they live alone. By forcing us all into social isolation, one public health crisis—the coronavirus—is shining a bright light on another, loneliness. It will be some time before we have a vaccine for the coronavirus. But the antidote to loneliness is accessible to all of us: friendship.Those who valued friendship as much as family had higher levels of health and happiness. All too often we fail to appreciate what we have until it’s gone. And this shared global moment has illuminated how significant friends are to day-to-day happiness. Science has been accumulating evidence that friendship isn’t just critical for our happiness but our health and longevity. Its presence or absence matters at every point in life, but the cumulative effects of either show up most starkly in the later stages of life. That is also the moment when demographics and health concerns can conspire to make friendships harder to find or sustain. As the world hits pause, it’s worth reminding ourselves why friendship is more important now than ever.Friendship has long been understood to be valuable and pleasurable. Ancient Greek philosophers enjoyed debating its virtues, in the company of friends. But friendship has largely been considered a cultural phenomenon, a pleasant by-product of the human capacity for language and living in groups. In the 1970s and 1980s, a handful of epidemiologists and sociologists began to establish a link between social relationships and health. They showed those who were more socially isolated were more likely to die over the course of the studies. In 2015, a meta-analysis of more than 3 million people whose average age was 66 showed that social isolation and loneliness increased the risk of early mortality by up to 30 percent.1 Yet loneliness and social isolation are not the same thing. Social isolation is an objective measure of the number and extent of social contact a person has day to day. Loneliness is a subjective feeling of mismatch between how much social connection you want and how much you have.Once the link between health and relationships was established in humans, it was noticed in other species as well. Primatologists studying baboons in Africa remarked that when female baboons lost their primary grooming partners to lions or drought, they worked to build bonds with other animals in place of the one they’d lost. When the researchers analyzed the social behavior of the animals and their outcomes over generations, they found in multiple studies that the animals with the strongest social networks live longer and have more and healthier babies than those that are more isolated.2 Natural selection has resulted in survival of the friendliest.Since baboons don’t drive each other to the hospital, something deeper than social support must be at work. Friendship is getting “under the skin,” as biologists say. Some of the mechanisms by which it works have yet to be explained, but studies have demonstrated that social connection improves cardiovascular functioning, reduces susceptibility to inflammation and viral disease, sharpens cognition, reduces depression, lowers stress, and even slows biological aging.3We also now have a clearer definition of what friendship is. Evolutionary biologists concluded that friendship in monkeys—as well as people—required at least three things: it had to be long-lasting, positive, and cooperative. When an anthropologist looked for consistent definitions of friendship across cultures, he found something similar. Friendships were described as positive, and they nearly always include a willingness to help, especially in times of crisis. What friendship is about at the end of the day is creating intensely bonded groups that act as protection against life’s stresses.4Social connection reduces depression, lowers stress, and even slows biological aging. That buffering effect is particularly powerful as we age. Those first epidemiology studies focused on people in the middle of life. In 1987, epidemiologist Teresa Seeman of the University of California, Los Angeles, wondered if age and type of relationship mattered for health.5 She found that for those under 60, whether or not they were married mattered most. Being unmarried in midlife put people at greater risk of dying earlier than normal. But that did not turn out to be true for the oldest groups. For those over 60, close ties with friends and relatives mattered more than having a spouse. “That was a real lightbulb that went on,” Seeman says.In a 2016 study, researchers at the University of North Carolina found that in both adolescence and old age, having friends was associated with a lower risk of physiological problems.6 The more friends you had, the lower the risk. By contrast, adults in middle age were less affected by variation in how socially connected they were. But the quality of their social relationships—whether friendships provided support or added strain—mattered more. Valuing friendship also proved increasingly important with age in a 2017 study by William Chopik of Michigan State University. He surveyed more than 270,000 adults from 15 to 99 years of age and found that those who valued friendship as much as family had higher levels of health, happiness, and subjective well-being across the lifespan. The effects were especially strong in those over 65. As you get older, friendships become more important, not less; whether you’re married is relatively less significant.7There’s a widespread sense, especially among younger people, that people are lonely post-retirement. The truth is more complicated. Social networks do get smaller later in life for a variety of reasons. In retirement, people lose regular interaction with colleagues. Most diseases, and the probability of getting them, worsen with age. It’s more likely you will lose a spouse. Friends start to die as well. Mental and physical capacities may diminish, and social lives may be limited by hearing loss or reduced mobility.Yet some of this social-narrowing is intentional. If time is of the essence, the motivation to derive emotional meaning from life increases, says Laura Carstensen, director of the Stanford Center for Longevity. She found that people choose to spend time with those they really care about. They emphasize quality of relationships over quantity. While family members fill much of a person’s inner social circle, friends are there, too, and regularly fill in in the absence of family. A related, more optimistic perspective on retirement is that with fewer professional and family obligations, there are more hours for the things we want to do and the people with whom we want to do them.At all stages of life, how we do friendship—whether we focus on one or two close friends or socialize more widely—has to do with our natural levels of sociability and motivation. Those vary, of course. I recently spoke with a man who had retired to Las Vegas. When he and his wife moved to their new house, his wife began baking cookies and distributing them to neighbors. She started throwing block parties for silly holidays and those neighbors showed up. No one had bothered to organize such a thing before. Even in retirement, this woman is what psychologists call a “social broker”—someone who brings people together. She has most likely always been friendly.What best predicted health wasn’t cholesterol levels, but satisfaction in relationships. How you live your life before you reach 60 makes a difference, experts on aging say. Friendship is a lifelong endeavor, but not everyone treats it that way. Think of relationships the way we do smoking, says epidemiologist Lisa Berkman of Harvard University. “If you start smoking when you’re 14, and stop smoking when you’re 65, in many ways, the damage is done,” she says “It’s not undoable. Stopping makes some things better. It’s worth doing but it’s very late in the game.” Similarly, if you only focus on friendships when your family and professional obligations slow, you will be at a disadvantage. Damage will have been done. The payoff in making friendship a priority was born out in the long-running Harvard Study of Adult Development, which followed more than 700 men for the entire course of their lives. What best predicted how healthy those men were at 80 wasn’t middle-aged cholesterol levels, it was how satisfied they were in their relationships at 50.8Fortunately, it is possible to make new friends at every stage of life. In Los Angeles, I met a group of 70-something women who bonded as volunteers for Generation Xchange, an educational and community health nonprofit. The program places older adults in early elementary classrooms as teachers’ aids for a school year. As a result of the extra adult attention in class, the children’s reading scores have gone up and behavioral problems have gone down. The volunteers’ health has improved—they’ve lost weight, and lowered blood pressure and cholesterol. But they have also become friends, which is just what UCLA’s Seeman had in mind when she started the program. “One of the reasons our program may be successful is that we are motivating them to get engaged through their joint interest in helping the kids,” Seeman says. “It takes the pressure off of making friends. You can start getting to know each other in the context of the school and our team. Hopefully, the friendships can grow out of that.”Concerns about loneliness among the elderly are well-founded. Demographics are not working in favor of the fight against loneliness. By 2035, older adults are projected to outnumber children for the first time in American history. Because of drops in marriage and childbearing, more of those older adults will be unmarried and childless than ever before. The percentage of older adults living alone rose steadily through the 20th century, and now hovers at 27 percent. And a digital divide still exists between older adults and their children and grandchildren, according to recent studies. That means older adults are less able to use virtual technology like Zoom to stay connected during the COVID-19 pandemic—though some are learning. Laura Fisher, a personal trainer in New York City, found that putting her business online meant training older clients one-on-one in videoconferencing. She now works out with one of her young clients in New York City and her client’s grandmother in Israel. Generally, older adults who use social media report more support from both their grown children and their friends. “For older people, social media is a real avenue of connection, of relational well-being,” says psychologist Jeff Hancock who runs the social media lab at Stanford University.That is good news in this moment of enforced social isolation. So is the fact that being apart has reminded so many of us of how much we enjoy being together. For my part, I sent those flowers to my mother-in-law after all when I discovered contactless delivery. When the flowers arrived, we spoke again. And then I called her again two days later. “It’s great to talk to you,” she said.Lydia Denworth is a contributing editor for Scientific American and the author of Friendship: The Evolution, Biology, and Extraordinary Power of Life’s Fundamental Bond.Lead image: SanaStock / ShutterstockReferences1 Holt-Lunstad, J., et al.

av The Ecological Vision That Will Save Us - Issue 84: Outbreak By nautil.us Published On :: Wed, 22 Apr 2020 15:30:00 +0000 The marquee on my closed neighborhood movie theater reads, “See you on the other side.” I like reading it every day as I pass by on my walk. It causes me to envision life after the coronavirus pandemic. Which is awfully hard to envision now. But it’s out there. When you have a disease and are in a hospital, alone and afraid, intravenous tubes and sensor wires snaking from your body into digital monitors, all you want is to be normal again. You want nothing more than to have a beer in a dusky bar and read a book in amber light. At least that’s all I wanted last year when I was in a hospital, not from a coronavirus. When, this February, I had that beer in a bar with my book, I was profoundly happy. The worst can pass.With faith, you can ask how life will be on the other side. Will you be changed personally? Will we be changed collectively? The knowledge we’re gaining now is making us different people. Pain demands relief, demands we don’t repeat what produced it. Will the pain of this pandemic point a new way forward? It hasn’t before, as every war attests. This time may be no different. But the pandemic has slipped a piece of knowledge into the body public that may not be easy to repress. It’s an insight scientists and poets have voiced for centuries. We’re not apart from nature, we are nature. The environment is not outside us, it is us. We either act in concert with the environment that gives us life, or the environment takes life away.Guess which species is the bully? No animal has had the capacity to modify its niche the way we have. Nothing could better emphasize our union with nature than the lethal coronavirus. It’s crafted by a molecule that’s been omnipresent on Earth for 4 billion years. Ribonucleic acid may not be the first bridge from geochemical to biochemical life, as some scientists have stated. But it’s a catalyst of biological life. It wrote the book on replication. RNA’s signature molecules, nucleotides, code other molecules, proteins, the building blocks of organisms. When RNA’s more chemically stable kin, DNA, arrived on the scene, it outcompeted its ancestor. Primitive organisms assembled into cells and DNA set up shop in their nucleus. It employed its nucleotides to code proteins to compose every tissue in every multicellular species, including us. A shameless opportunist, RNA made itself indispensable in the cellular factory, shuttling information from DNA into the cell’s power plant, where proteins are synthesized.RNA and DNA had other jobs. They could be stripped down to their nucleotides, swirled inside a sticky protein shell. That gave them the ability to infiltrate any and all species, hijack their reproductive machinery, and propagate in ways that make rabbits look celibate. These freeloading parasites have a name: virus. But viruses are not just destroyers. They wear another evolutionary hat: developers. Viruses “may have originated the DNA replication system of all three cellular domains (archaea, bacteria, eukarya),” writes Luis P. Villareal, founding director of the Center for Virus Research at the University of California, Irvine.1 Their role in nature is so successful that DNA and RNA viruses make up the most abundant biological entities on our planet. More viruses on Earth than stars in the universe, scientists like to say.Today more RNA than DNA viruses thrive in cells like ours, suggesting how ruthless they’ve remained. RNA viruses generally reproduce faster than DNA viruses, in part because they don’t haul around an extra gene to proofread their molecular merger with others’ DNA. So when the reckless RNA virus finds a new place to dwell, organisms become heartbreak hotels. Once inside a cell, the RNA virus slams the door on the chemical saviors dispatched by cells’ immunity sensors. It hijacks DNA’s replicative powers and fans out by the millions, upending cumulative cellular functions. Like the ability to breathe.Humans. We love metaphors. They allow us to compare something as complex as viral infection to something as familiar as an Elvis Presley hit. But metaphors for natural processes are seldom accurate. The language is too porous, inviting our anthropomorphic minds to close the gaps. We imagine viruses have an agenda, are driven by an impetus to search and destroy. But nature doesn’t act with intention. It just acts. A virus lives in a cell like a planet revolves around a sun.Biologists debate whether a virus should be classified as living because it’s a deadbeat on its own; it only comes to life in others. But that assumes an organism is alive apart from its environment. The biochemist and writer Nick Lane points out, “Viruses use their immediate environment to make copies of themselves. But then so do we: We eat other animals or plants, and we breathe in oxygen. Cut us off from our environment, say with a plastic bag over the head, and we die in a few minutes. One could say that we parasitize our environment—like viruses.”2Our inseparable accord with the environment is why the coronavirus is now in us. Its genomic signature is almost a perfect match with a coronavirus that thrives in bats whose habitats range across the globe. Humans moved into the bats’ territory and the bats’ virus moved into humans. The exchange is just nature doing its thing. “And nature has been doing its thing for 3.75 billion years, when bacteria fought viruses just as we fight them now,” says Shahid Naeem, an upbeat professor of ecology at Columbia University, where he is director of the Earth Institute Center for Environmental Sustainability. If we want to assign blame, it lies with our collectively poor understanding of ecology.FLYING LESSON: Bats don’t die from the same coronavirus that kills humans because the bat’s anatomy fights the virus to a draw, neutralizing its lethal moves. What’s the deal with the human immune system? We don’t fly.Martin Pelanek / ShutterstockOrganisms evolve with uniquely adaptive traits. Bats play many ecological roles. They are pollinators, seed-spreaders, and pest-controllers. They don’t die from the same coronavirus that kills humans because the bat’s anatomy fights the virus to a draw, neutralizing its lethal moves. What’s the deal with the human immune system? We don’t fly. “Bats are flying mammals, which is very unusual,” says Christine K. Johnson, an epidemiologist at the One Health Institute at the University of California, Davis, who studies virus spillover from animals to humans. “They get very high temperatures when they fly, and have evolved immunological features, which humans haven’t, to accommodate those temperatures.”A viral invasion can overstimulate the chemical responses from a mammal’s immune system to the point where the response itself causes excessive inflammation in tissues. A small protein called a cytokine, which orchestrates cellular responses to foreign invaders, can get over-excited by an aggressive RNA virus, and erupt into a “storm” that destroys normal cellular function—a process physicians have documented in many current coronavirus fatalities. Bats have genetic mechanisms to inhibit that overreaction. Similarly, bat flight requires an increased rate of metabolism. Their wing-flapping action leads to high levels of oxygen-free radicals—a natural byproduct of metabolism—that can damage DNA. As a result, states a 2019 study in the journal Viruses, “bats probably evolved mechanisms to suppress activation of immune response due to damaged DNA generated via flight, thereby leading to reduced inflammation.”3Bats don’t have better immune systems than humans; just different. Our immune systems evolved for many things, just not flying. Humans do well around the cave fungus Pseudogymnoascus destructans, source of the “white-nose syndrome” that has devastated bats worldwide. Trouble begins when we barge into wildlife habitats with no respect for differences. (Trouble for us and other animals. White-nose syndrome spread in part on cavers’ shoes and clothing, who tracked it from one site to the next.) We mine for gold, develop housing tracts, and plow forests into feedlots. We make other animals’ habitats our own.Our moralistic brain sees retribution. Karma. A viral outbreak is the wrath that nature heaps on us for bulldozing animals out of their homes. Not so. “We didn’t violate any evolutionary or ecological laws because nature doesn’t care what we do,” Naeem says. Making over the world for ourselves is just humans being the animals we are. “Every species, if they had the upper hand, would transform the world into what it wants,” Naeem says. “Birds build nests, bees build hives, beavers build dams. It’s called niche construction. If domestic cats ruled the world, they would make the world in their image. It would be full of litter trays, lots of birds, lots of mice, and lots of fish.”But nature isn’t an idyllic land of animal villages constructed by evolution. Species’ niche-building ways have always brought them into contact with each other. “Nature is ruled by processes like competition, predation, and mutualism,” Naeem says. “Some of them are positive, some are negative, some are neutral. That goes for our interactions with the microbial world, including viruses, which range from super beneficial to super harmful.”Nature has been doing its thing for 3.75 billion years, when bacteria fought viruses as we fight them now. Ultimately, nature works out a truce. “If the flower tries to short the hummingbird on sugar, the hummingbird is not going to provide it with pollination,” Naeem says. “If the hummingbird sucks up all the nectar and doesn’t do pollination well, it’s going to get pinged as well. Through this kind of back and forth, species hammer out an optimal way of getting along in nature. Evolution winds up finding some middle ground.” Naeem pauses. “If you try to beat up everybody, though, it’s not going to work.”Guess which species is the bully? “There’s never been any species on this planet in its entire history that has had the capacity to modify its niche the way we have,” Naeem says. Our niche—cities, farms, factories—has made the planet into a zoological Manhattan. Living in close proximity with other species, and their viruses, means we are going to rub shoulders with them. Dense living isn’t for everyone. But a global economy is. And with it comes an intercontinental transportation system. A virus doesn’t have a nationality. It can travel as easily from Arkansas to China as the other way around. A pandemic is an inevitable outcome of our modified niche.Although nature doesn’t do retribution, our clashes with it have mutual consequences. The exact route of transmission of SARS-CoV-2 from bat to humans remains unmapped. Did the virus pass directly into a person, who may have handled a bat, or through an intermediate animal? What is clear is the first step, which is that a bat shed the virus in some way. University of California, Davis epidemiologist Johnson explains bats shed viruses in their urine, feces, and saliva. They might urinate on fruit or eat a piece of it, and then discard it on the ground, where an animal may eat it. The Nipah virus outbreak in 1999 was spurred by a bat that left behind a piece of fruit that came in contact with a domestic pig and humans. The Ebola outbreaks in the early 2000s in Central Africa likely began when an ape, who became bushmeat for humans, came in contact with a fruit bat’s leftover. “The same thing happened with the Hendra virus in Australia in 1994,” says Johnson. “Horses got infected because fruit bats lived in trees near the horse farm. Domesticated species are often an intermediary between bats and humans, and they amplify the outbreak before it gets to humans.”Transforming bat niches into our own sends bats scattering—right into our backyards. In a study released this month, Johnson and colleagues show the spillover risk of viruses is the highest among animal species, notably bats, that have expanded their range, due to urbanization and crop production, into human-run landscapes.4 “The ways we’ve altered the landscape have brought a lot of great things to people,” Johnson says. “But that has put wildlife at higher pressures to adapt, and some of them have adapted by moving in with us.”Pressures on bats have another consequence. Studies indicate physiological and environmental stress can increase viral replication in them and cause them to shed more than they normally do. One study showed bats with white-nose syndrome had “60 times more coronavirus in their intestines” as uninfected bats.5 Despite evidence for an increase in viral replication and shedding in stressed bats, “a direct link to spillover has yet to be established,” concludes a 2019 report in Viruses.3 But it’s safe to say that bats being perpetually driven from their caves into our barns is not ideal for either species.As my questions ran out for Columbia University’s Naeem, I asked him to put this horrible pandemic in a final ecological light for me.“We think of ourselves as being resilient and robust, but it takes something like this to realize we’re still a biological entity that’s not capable of totally controlling the world around us,” he says. “Our social system has become so disconnected from nature that we no longer understand we still are a part of it. Breathable air, potable water, productive fields, a stable environment—these all come about because we’re part of this elaborate system, the biosphere. Now we’re suffering environmental consequences like climate change and the loss of food security and viral outbreaks because we’ve forgotten how to integrate our endeavors with nature.”A 2014 study by a host wildlife ecologists, economists, and evolutionary biologists lays out a plan to stem the tide of emergent infectious diseases, most of which spawned in wildlife. Cases of emergent infectious diseases have practically quadrupled since 1940.6 World leaders could get smart. They could pool money for spillover research, which would identify the hundreds of thousands of potentially lethal viruses in animals. They could coordinate pandemic preparation with international health regulations. They could support animal conservation with barriers that developers can’t cross. The scientists give us 27 years to cut the rise of infectious diseases by 50 percent. After that, the study doesn’t say what the world will look like. I imagine it will look like a hospital right now in New York City.Patients lie on gurneys in corridors, swaddled in sheets, their faces shrouded by respirators. They’re surrounded by doctors and nurses, desperately trying to revive them. In pain, inconsolable, and alone. I know they want nothing more than to see their family and friends on the other side, to be wheeled out of the hospital and feel normal again. Will they? Will others in the future? It will take tremendous political will to avoid the next pandemic. And it must begin with a reckoning with our relationship with nature. That tiny necklace of RNA tearing through patients’ lungs right now is the world we live in. And have always lived in. We can’t be cut off from the environment. When I see the suffering in hospitals, I can only ask, Do we get it now?Kevin Berger is the editor of Nautilus.References 1. Villareal, L.P. The Widespread Evolutionary Significance of Viruses.
