For many new parents, the daunting reality of caring for a child hits like an anvil to the chest. After you’ve done everything you can to keep them safe—buying everything from car seats to protective mittens —there’s an overwhelming swirl of terror when you learn that baby’s shampoo contains known carcinogens. Those cute new bottles are laced with BPA, while the after-bath lotion is chock-full of phthalates—both components linked to a variety of unpleasant health and developmental side affects. You’re trying your best, and learn that your best could be poisoning your kid.


Social enterprise Mighty Nest is making parents’ lives easier and keeping kids safe by employing what might be the hottest trend in e-commerce—curation—to narrow parents’ retail options to safe, non-toxic products.

From reading labels to launching a startup

Like many new parents, Kristen Conn went through the shock of learning about toxic ingredients. Before she had children, she’d never really questioned what she bought in stores. A book she read during her pregnancy recommended switching to a natural deodorant, because chemicals in conventional antiperspirants could harm her baby. After her daughter was born, news broke about BPA. “It became kind of overwhelming,” she says. “There’s a lot of information out there and trying to figure out what you need to change… you can’t just all of a sudden throw out everything in your house and start over again.”

First, she researched and carefully replaced the family’s skin care products. She only bought BPA-free plastic, then started cutting out plastic altogether.

Meanwhile, Kristen’s husband Chris Conn was feeling the itch to live a dream they’d long planned for—running his own business after 14 years in internet-related work at conglomerates like NBC and the Tribune Company. Watching Kristen methodically tackle the problem of keeping their family safe, he had the idea for an online retailer that could serve needs that were becoming obvious in his own home.

Kristen faced three problems simultaneously: There was a glut of information, but often not enough about what parents typically buy; finding non-toxic products was extremely difficult; and judgment from parents was par for the course—either you’re crazy if you think toxic ingredients are an issue, or you’re crazy if you don’t.

With these ideas in mind, the couple created Mighty Nest in August 2008. It would be more than a year before the retail site launched, allowing time for planning, wooing investors, extensive research and product vetting to ensure that, as Chris puts it, “every single thing you buy from us is safe.”

Ahead of the retail curation trend

“The web as we’ve known it is broken,” says Steven Rosenbaum, author of Curation Nation. “The volume of content exceeds the way we’ve historically navigated the web.” In terms of general content, he notes, the amount of video uploaded to YouTube in one 24-hour period would take 98 years to view. As is being rapidly proven by Twitter, Tumblr and Pinterest, people crave ways to contextualize all that information. This is particularly true in retail.

Steven Addis, CEO of socially conscious branding firm Addis Creson, says he was among the first to apply “curation” to business in the way its used today. Addis says sharing a strong point of view with customers builds loyalty. Knowing and agreeing with a retailer’s curatorial standards holds huge appeal, because instead of hours spent researching online or reading labels, “I get to just be a shopper again.”

For parents like the Conns, safety is paramount. “It’s scary to think about some of the things in our hygiene and household cleaning products today… I’m not willing to risk the health and wellbeing of my children,” says Christine Drown, a mother and Mighty Nest customer.

When Chris launched Mighty Nest, Kristen told him, “Ok, I’ll help you a little bit.” This evolved into a vetting process in which Kristen and one other employee evaluate every product the company sells. In each of Mighty Nest’s retail categories, from toys to kitchenware, potential products are eliminated if they contain known hazards like BPA, phthalates, lead, formaldehyde, or PVC. From that pool, Mighty Nest draws products with components customers want—for instance, a coffee maker with no plastic parts. Next, they call manufacturers and start (politely) grilling, with questions about production, testing, and how color is added, among others. “If they won’t answer our questions, we won’t sell their products,” Chris says

Once deemed safe, new products are tested by Mighty Nest employees in their own homes for functionality, durability, and ease of use. Mighty Nest selects what it considers the top options from whatever products make it through that last hoop. “We don’t feel that parents have time to choose between 15 or 20 or 30 different alternatives,” Chris says. “We’re going to give them the best three or five.”

This is precisely what makes curation a boon for customers. “Mighty Nest is an awesome example of retail curation,” Rosenbaum says. “Online, the race has been to build the biggest collection of products. But now, customers are looking for stores that have a distinctly editorial point of view. ‘Healthy and safe’ isn’t a marketing campaign. It’s in their digital DNA.”

Loyalty through community

Kristen remembers her initial experience as a child-conscious shopper, “when I was at home, doing the research on my own on my laptop, I felt kind of alone in this thinking.” One outgrowth of Mighty Nest is an online network of similarly minded parents and customers.

On Facebook, Mighty Nest shares products, articles and recipes. Customers are doing what all social network administrators hope for—creating true community. Customers are so excited about shopping with Mighty Nest that even a post about a mixing bowl gets a comment like “just got a 4 qt pyrex (made in USA!) love it!!!!!!!!!” Careful shoppers, like Drown, who trust the company’s research methods still contact them with further questions.

“We’re a place that you have a relationship with,” Chris says. “We’re not just a retail store.”

The company is growing steadily, having doubled its revenue between its first and second full years of operation. Building customer loyalty has been important on multiple fronts. Products listed on Mighty Nest aren’t usually the cheapest in their categories, but they’re also not the most expensive. The curation process results in a line made from basic but incredibly durable components, like 304-grade stainless steel and tempered glass.

“An individual purchase on its own ends up costing more, but you end up buying fewer things,” Chris says. It’s a long-run savings with a green spin, as long-lasting products cut consumption.

Rosenbaum says that customers understand you can save money or time, but not both. “The question for sites like Mighty Nest will be if consumers use their quality filters to test new products, but shift their staple shopping to the large online retailers,” he says.

This is why loyalty and trust matter. Shoppers stick with companies like Mighty Nest because they’ve built credibility and share a vision. To Addis, curated e-commerce represents the new era of small business. We have plenty of reason to support local small business, “but when we’re looking for a much better selection out there and we need the web, this is the new cottage industry—and Amazon is not.”

  • Foreign aid’s hidden benefit: Recipients are more likely to pay the generosity forward
    Photo credit: Kim Hong-Ji/Getty ImagesSouth Korean soldiers oversee the arrival of a batch of Johnson & Johnson’s Janssen COVID-19 vaccines donated by the U.S. government on June 5, 2021.

    Foreign aid may not improve how recipients view donor countries – but it can set off a chain of goodwill that spreads far beyond the original act of giving.

    That is what a colleague and I found when we studied how South Koreans responded to COVID-19 vaccines donated by the United States.

    The South Korean government reserved donated Johnson & Johnson vaccines for military reservists and, for medical reasons, excluded anyone under 30. As a result, we could compare the views of South Koreans just above and below that threshold.

    We found that the donated vaccines did not improve people’s views of the United States. South Koreans who received American vaccines reported similar views of the U.S. as those who had not been vaccinated.

    Yet the results were striking in another way. Those who received donated American vaccines became more supportive of their own government sending aid abroad. Recipients shifted from neutrality on the matter to expressing moderate support for foreign aid, scoring about one point higher on a seven-point scale than those who didn’t make the eligibility cutoff.

    There is also evidence that these effects extend beyond direct recipients. South Koreans who were simply told that the U.S. was providing vaccine aid to developing countries also became more supportive of their own government doing the same – though this effect was concentrated among political moderates.

    Together, these patterns point to what social scientists call “generalized reciprocity” – the impulse not to repay kindness directly but to pass it on. In this way, one act of aid can prompt another, and spread across borders.

    Why it matters

    From Washington and London to Berlin and Tokyo, foreign aid budgets have been cut. In November 2020, former U.S. Agency for International Development Administrator Samantha Power invoked a common assumption when she argued that providing vaccines abroad would restore American leadership – that the value of aid lies in the goodwill it generates toward the donor.

    Our findings suggest this is one way aid can matter, but not necessarily the most important.

    Instead, aid may foster a form of international cooperation that does not depend on treaties or direct reciprocity between nations but emerges from ordinary people’s willingness to pass on goodwill.

    If aid can trigger chains of giving across borders, then how we assess its value may need to change. Current frameworks tend to emphasize donor nations’ direct returns or strategic benefits, but the cooperative effects we identify are largely invisible to those metrics.

    This suggests that current cuts may be shutting down effects that policymakers have not yet learned to measure – a form of international cooperation that, once set in motion, can generate cascading effects well beyond what any single donor nation could achieve alone.

    What we don’t know

    Important questions remain: Do similar patterns emerge with other forms of aid – such as disaster relief, food assistance or long-term development programs? And how long do these effects last?

    There are also hints that the threshold for triggering this response may be lower than previously thought. The effect persisted even when using eligibility for donated vaccines, rather than actual receipt, as the measure – suggesting proximity to aid, not just receipt, may be enough to activate the impulse to give.

    If evidence that past recipients of aid have themselves become donors strengthens public support for giving in donor countries, then aid may be more self-sustaining than critics assume – reinforced not just by its immediate effects, but by the example it sets.

  • Photographic memory is a myth – here’s what research really says about remembering

    Hollywood loves a superpower. Not all involve capes or cosmic rays. Some are cognitive: characters who can remember everything. In movies and on TV, viewers repeatedly encounter those with extraordinary minds who glance once at a page, a room or a face – and later recreate every detail with surgical precision.

    You see it everywhere: “Suits,” “Sherlock” and “The Girl with the Dragon Tattoo.” Even in children’s literature there’s fifth grader Cam Jansen, who activates her photolike memory by saying “Click!”

    Most recently, it appeared in the television series “The Pitt,” set in a hospital emergency department. When the digital patient board suddenly went offline, medical student Joy Kwon saved the day by effortlessly reciting from memory every lost detail – names, rooms, doctors, conditions, vitals. It’s a gripping moment. The stakes are high, recall is perfect, and the implication is clear: Some people have minds that function like high-resolution cameras.

    The idea of photographic memory is simple and powerful: Experience is captured objectively, stored completely and retrieved perfectly. See it once, keep it forever.

    There’s just one problem. There’s no scientific evidence it exists.

    Your memory doesn’t record, it reconstructs

    As a memory researcher, I understand that belief in photographic memory is common and the idea is compelling. But it is simply wrong.

    Human memory does not work like a recording device. It’s a reconstructive process even among those with the most extraordinary skills. When you recall an event, memory doesn’t just hand you your experiences the same way every time. It’s never a matter of simply accessing, retrieving and playing back a static record of a stored slice of the past.

    Rather, you reconstruct the past by piecing together the remnants of experience available to you in the moment of recollection. It’s a process shaped by a range of factors, including the search cues you use; your present knowledge, attitudes and goals; and your current state of mind or mood.

    Because each of these factors is dynamic and changing, you’ll remember the past differently today – if ever so slightly – from how you remembered it yesterday, and differently from how you’ll remember it tomorrow. What you remember is not only incomplete but also inexact.

    A closer look at extraordinary memory

    Some people, such as memory competition champions, do have extraordinary memories. They can memorize thousands of digits or entire decks of cards in minutes. Their feats are real, but they don’t come from a memory that takes mental snapshots.

    Instead, these people rely on strategies – mental frameworks built through thousands of hours of deliberate practice to scaffold their memory in specific domains. Without these strategies and in other aspects of life, their recall looks pretty much like everyone else’s. Experts’ performance reflects better methods, not different machinery.

    In the scientific literature, the ability that comes closest to photographic memory is eidetic imagery: a form of visual mental imagery in which people claim they can briefly continue to “see” pictures they carefully studied and that are then removed from view.

    This ability is rare, is seen mostly in children, and usually disappears by adolescence. Even at its peak, however, it falls short of the Hollywood ideal. Eidetic images fade quickly and are not perfectly accurate. They can include distortions and even details that were not seen.

    It’s exactly what you’d expect from a reconstructive memory system – and exactly what you would not expect from a literal recording.

    Forgetting is a feature and not a flaw

    The myth about photographic memories feeds into the idea that your memory has failed if you can’t remember – that if your memory worked right, it would operate like a camera. When you can’t retrieve information or you lose it entirely, it can feel like something has gone wrong.

    In reality, forgetting is functional. Without it, we’d never get by.

    For instance, people use their memories of the past to forecast the future. Perfect memory would be a liability. Forgetting washes out the details of specific episodes and retains the gist so you can apply past experiences to novel situations, not just those that exactly match what happened before.

    Forgetting also guards your emotional health. The dulling of memories for negative events, like say an embarrassing episode, makes it easier for you to move on than if you reexperienced all the details in full force every time the event came to mind.

    Forgetting protects your sense of self as well. Memories of your past form the foundation of your identity. To help maintain a stable self-concept, people selectively modify or even forget those memories that challenge their views of themselves.

    The rare individuals who come closest to having near-perfect memory often reveal the downsides. People with highly superior autobiographical memory can remember nearly every day of their lives in vivid detail. If you ask one of these people to recall what they did on Nov. 24, 1999, they likely can tell you.

    Their extraordinary ability seems to come from a habitual, even compulsive, reflection on their past and a focus on anchoring memories to dates. However, this skill is limited to autobiographical events, and they are prone to various kinds of memory distortions and errors just like everyone else.

    While this ability might sound like an advantage, many people with highly superior autobiographical memory describe it as exhausting. They struggle to move past negative experiences because their memories make them seem as sharp as ever.

    Accurate – and empowering – view of memory

    Beliefs about “perfect memory” shape how people judge studentseyewitnessespatients and even themselves. They influence legal decisions, educational practices and unrealistic expectations about what human minds can – and should – do.

    Letting go of the camera metaphor could be a step toward better understanding how memory works. The brain is not a roll of film, it’s a storyteller – one that edits, interprets and reshapes the past in light of the present.

    And that’s not a limitation. It’s a superpower.

  • How workplace stress hijacks the nervous system to cause headaches − and a neurologist’s guide to managing them
    Photo credit: Sean Gladwell/Moment via Getty ImagesOngoing stress can send the nervous system into a state of heightened sensitivity.

    Many people finish the workday not just tired but wired. Their mind keeps racing, their body feels tense, and even in moments that should be restful they feel a lingering sense of urgency. Conversations replay in their mind, unfinished tasks resurface, and their nervous system seems unwilling to power down.

    You may recognize this experience. It has become so common that it is often accepted as the norm in modern professional life. Yet this persistent state of activation carries consequences for physical health, especially for people prone to headaches.

    As a board-certified neurologist who specializes in headache medicine, I see a lot of patients whose pain increases from the high-pressure work culture prevalent today. While it might seem beyond your control, there are some steps you can take.

    Stress and the nervous system

    Stress is not inherently harmful. In fact, when experienced in short bursts, stress can be beneficial by increasing focus, improving performance and preparing the body to handle challenges. However, problems arise when stress becomes chronic and relentless.

    The nervous system perceives and processes both stress and pain. Built to be highly adaptable, it continually responds to internal signals and external factors, constantly recalibrating to maintain balance. When the brain continuously perceives ongoing demands without adequate recovery, it keeps the body in a prolonged state of alertness.

    During these periods of ongoing stress, hormones such as cortisol and adrenaline remain persistently elevated. In this sensitized state, signals that would typically be ignored or interpreted as minor can start to feel much more intense.

    This state leads to an increase in heart rate and sustained muscle tension, with the nervous system transitioning into continuous fight or flight mode. In the context of headaches, this sensitization can lower the threshold for pain, making it easier for a headache to start and harder for it to stop.

    Over time, this constant activation can disrupt the body’s natural balance and create an environment for headache disorders to develop or worsen.

    Chronic stress acts as both a trigger and an exacerbating factor for migraines. The neurological system of people who experience migraines is comparatively more responsive to environmental changes, including variations in sleep patterns, the environment, hormonal fluctuations and stress intensity.

    This means that persistent exposure to stress may drive up frequency and severity of migraine episodes. In addition, muscle tension in the neck, shoulders and scalp – a frequent effect of stress – can cause tension headaches, too.

    Extended periods of sitting, sustained concentration and physical tension during the workday can contribute to the development of tension headaches in the later hours of the day.

    The role of sleep

    Chronic stress can also have a profound impact on sleep quality. Many people who feel persistently wired at the end of the workday struggle to fall asleep or stay asleep. That fitful sleep may lack the restorative qualities necessary for recovery.

    Poor sleep can, in turn, perpetuate the stress cycle, leaving the brain further sensitized and increasing the likelihood of headaches the following day. This loop can be difficult to break, as fatigue reduces resilience and amplifies the sense of being overwhelmed that comes with stress.

    In addition to affecting sleep, chronic stress impairs concentration and cognitive function. When the brain remains in a state of constant vigilance, scanning for demands and threats, it becomes harder to focus, be creative and solve problems. As a result, productivity declines, errors become more frequent and frustration mounts, adding to the overall stress burden.

    Headaches that occur alongside these cognitive challenges can further disrupt daily life, making even routine tasks feel difficult.

    Managing work stress

    Understanding the connection between stress and the nervous system points to some steps you can take to shift the nervous system out of its constantly activated state. You’ll never eliminate stress entirely – that’s neither realistic nor necessary. But it is possible to create intentional space for the body to reset:

    Small, consistent strategies that address both biological and lifestyle causes of headaches can minimize the effects of chronic stress and encourage nervous system regulation. Over time, these strategies can gradually reduce headache frequency and severity, improving overall quality of life.
