Its 9:30 p.m. Snack time. A sacred fourth meal, when I pull out my handwash-only kobachi and drop in a small handful of Blue Diamond Smokehouse almonds. Ive been eating them for more years than I care to admit, appreciating the mix of natural (high protein and fiber) almonds with a splash of addictive processing (mmm, hickory smoke flavor and maltodextrin) to keep them feeling dangerous. Its the perfect portion of the perfect snack in the perfect bowl. Almost. [Image: Blue Diamond] The problem with Blue Diamond Smokehouse isnt the product. Its the packaging. Specifically, the Ziploc-esque “resealable zipper stops working, like clockwork, when Im about halfway through the bag. The plastic zip itself seems to hold too strongly, so that inevitably, theres a point when I open the bag, and the heat-sealed weld gives out. The zip stays zipped, but now its attached to only one side of the bag. ONE SIDE!!! A bag that now gapes open, possibly in shock from my own ineptitude in opening and closing a snack. I know its not my fault. Its the damn dysfunctional bag. But like dropping a cheap glass, Im left with an unnecessary burden of guilt. Was it something I did, Blue Diamond?? I can change! Ill do better next time! (I never do.) WHY DOES NOTHING EVER GO RIGHT IN MY LIFE????!?? WHY DO I DRIVE ALL SOURCES OF MONOUNSATURATED FATS AWAY??!??! From there on out, Im left with this domestic conundrum: Shove the almonds into another bag (feels wasteful, and the powder is gonna stick to everything)or curse . . . curl the bag up the best I can . . . and wedge it between two canned goods to keep it from springing open. Inevitably, I choose the latter. But more air gets in over the coming weeks. The smoky almonds grow stale. This sounds dramatic. I am being dramatic! But also, cmon: 3 gallons of water go into each nut. That means my 25-ounce pack represents 2,100 gallons of water. And Blue Diamond cant even take the time to make sure that so much investment isnt leaking all over my pantry. Resealable packs suck To be fair, Blue Diamond is far from the only culprit when it comes to poorly built zips. Since the late 1980s, resealable bags have taken over supermarket shelves for products including nuts, pre-shredded cheese, and frozen nuggets. Into the 1990s, these technologies were largely perfected to replace boxed goods with soft packaging in pyramidic forms, creating bags with a wide bottom and thin top that stood up and stood out on the shelf. Despite decades of manufacturing innovations, resealable packs can still be stupidly hard to cut open without hitting the zip. Bits of food can clog the seals. And, more and more, Im noticing how one side of the zip can inevitably fail, as with Blue Diamond, leaving the pack less than airtight. But when they work, its the best UX that the American supermarket has to offer (dont get me started on self-checkout!), inevitably helping to keep food fresh and reduce food waste. As much as 40% of Americas food is thrown away each year. And resealable packs help reduce this numberall without introducing more packaging (looking at you, Ziploc!) to solve the problem. So consider this an open call for Blue Diamond, and all those making suss resealable products, to rethink their packaging. We must have the technology to actually seal bags shut . . . again . . . and again.

Across Appalachia, rust-colored water seeps from abandoned coal mines, staining rocks orange and coating stream beds with metals. These acidic discharges, known as acid mine drainage, are among the regions most persistent environmental problems. They disrupt aquatic life, corrode pipes, and can contaminate drinking water for decades. However, hidden in that orange drainage are valuable metals known as rare earth elements that are vital for many technologies the U.S. relies on, including smartphones, wind turbines, and military jets. In fact, studies have found that the concentrations of rare earths in acid mine waste can be comparable to the amount in ores mined to extract rare earths. Scientists estimate that more than 13,700 miles of U.S. streams, predominantly in Pennsylvania and West Virginia, are contaminated with acid mine discharge. A closer look at acid mine drainage from abandoned mines in Pennsylvania from the Pennsylvania Fish and Boat Commission We and our colleagues at West Virginia University have been working on ways to turn the acid waste in those bright orange creeks into a reliable domestic source for rare earths while also cleaning the water. Experiments show extraction can work. If states can also sort out who owns that mine waste, the environmental cost of mining might help power a clean energy future. Rare earths face a supply chain risk Rare earth elements are a group of 17 metals, also classified as critical minerals, that are considered vital to the nations economy or security. Despite their name, rare earth elements are not all that rare. They occur in many places around the planet, but in small quantities mixed with other minerals, which makes them costly and complex to separate and refine. China controls about 70% of global rare earth production and nearly all refining capacity. This near monopoly gives the Chinese government the power to influence prices, export policies, and access to rare earth elements. China has used that power in trade disputes as recently as 2025. The United States, which currently imports about 80% of the rare earth elements it uses, sees Chinas control over these critical minerals as a risk and has made locating domestic sources a national priority. Although the U.S. Geological Survey has been mapping potential locations for extracting rare earth elements, getting from exploration to production takes years. Thats why unconventional sources, like extracting rare earth elements from acid mine waste, are drawing interest. Turning a mine waste problem into a solution Acid mine drainage forms when sulfide minerals, such as pyrite, are exposed to air during mining. This creates sulfuric acid, which then dissolves heavy metals such as copper, lead, and mercury from the surrounding rock. The metals end up in groundwater and creeks, where iron in the mix gives the water an orange color. Expensive treatment systems can neutralize the acid, with the dissolved metals settling into an orange sludge in treatment ponds. For decades, that sludge was treated as hazardous waste and hauled to landfills. But scientists at West Virginia University and the National Energy Technology Laboratory have found that it contains concentrations of rare earth elements comparable to those found in mined ores. These elements are also easier to extract from acid mine waste because the acidic water has already released them from the surrounding rock. Experiments have shown how the metals can be extracted: Researchers collected sludge, separated out rare earth elements using water-safe chemistry, and then returned the cleaner water to nearby streams. It is like mining without digging, turning something harmful into a useful resource. If scaled up, this process could lower cleanup costs, create local jobs, and strengthen Americas supply of materials needed for renewable energy and high-tech manufacturing. But theres a problem: Who owns the recovered minerals? The ownership question Traditional mining law covers minerals underground, not those extracted from water naturally running off abandoned mine sites. Nonprofit watershed groups that treat mine waste to clean up the water often receive public funding meant solely for environmental cleanup. If these groups start selling recovered rare earth elements, they could generate revenue for more stream cleanup projects, but they might also risk violating grant terms or nonprofit rules. To better understand the policy challenges, we surveyed mine water treatment operators across Pennsylvania and West Virginia. The majority of treatment systems were under landowner agreements in which the operators had no permanent property rights. Most operators said ownership uncertainty was one of the biggest barriers to investment in the recovery of rare earth elements, projects that can cost millions of dollars. Not surprisingly, water treatent operators who owned the land where treatment was taking place were much more likely to be interested in rare earth element extraction. West Virginia took steps in 2022 to boost rare earth recovery, innovation, and cleanup of acid mine drainage. A new law gives ownership of recovered rare earth elements to whoever extracts them. So far, the law has not been applied to large-scale projects. Across the border, Pennsylvanias Environmental Good Samaritan Act protects volunteers who treat mine water from liability but says nothing about ownership. This difference matters. Clear rules like West Virginias provide greater certainty, while the lack of guidance in Pennsylvania can leave companies and nonprofits hesitant about undertaking expensive recovery projects. Among the treatment operators we surveyed, interest in rare earth element extraction was twice as high in West Virginia than in Pennsylvania. The economics of waste to value Recovering rare earth elements from mine water wont replace conventional mining. The quantities available at drainage sites are far smaller than those produced by large mines, even though the concentration can be just as high, and the technology to extract them from mine waste is still developing. Still, the use of mine waste offers a promising way to supplement the supply of rare earth elements with a domestic source and help offset environmental costs while cleaning up polluted streams. Early studies suggest that recovering rare earth elements using technologies being developed today could be profitable, particularly when the projects also recover additional critical materials, such as cobalt and manganese, which are used in industrial processes and batteries. Extraction methods are improving, too, making the process safer, cleaner, and cheaper. Government incentives, research funding, and public-private partnerships could speed this progress, much as subsidies support fossil fuel extraction and have helped solar and wind power scale up in providing electricity. Treating acid mine drainage and extracting its valuable rare earth elements offers a way to transform pollution into prosperity. Creating policies that clarify ownership, investing in research, and supporting responsible recovery could ensure that Appalachian communities benefit from this new chapter, one in which cleanup and clean energy advance together.

Below, Jay Belsky shares five key insights from his new book, The Nature of Nurture: Rethinking Why and How Childhood Adversity Shapes Development. Belsky is emeritus professor of human development at the University of California, Davis. Whats the big idea? Seen through an evolutionary lens, early adversity can shape development in adaptive ways. And because children differ in their sensitivity to their environments, early experiences may matter a lot for some and much less for others. Listen to the audio version of this Book Biteread by Belsky himselfin the Next Big Idea app. 1. A radically transformed understanding of development It is beyond dispute that the Hubble Telescope, launched in 1990 (to say nothing of the James Webb Space Telescope launched 11 years later), radically transformed our understanding of the universe. To virtually everyone involved in the life sciences, Charles Darwins theory of adaptation by natural selection in the mid-19th century and William Hamiltons insights on kin selection and inclusive fitness in the mid-20th century have functioned much like these recent telescopic wonders in understanding life on planet Earth. This is true not simply with respect to human nature, as long highlighted by many evolutionary-minded scholars, but specifically with respect to why, how, and for whom early-life conditions shape, or fail to shape, child, adolescent, and even adult development. 2. Childhood adversity looks different when cast in evolutionary perspective What stimulated the radical shift in my thinking some three decades ago was the realization that the prevailing, mainstream view of development I cut my teeth on reflected an idealized, romanticized view of the human condition: Good experiences foster well-being, whereas bad things lead to disorder, dysregulation, and dysfunction. Putting on evolutionary lenses made me realize that because childhood adversityin the form, for example, of threat and deprivationwas not uncommon over the course of human history, the ways children develop in response to it likely evolved and reflect adaptation rather than problematic functioning, as so long presumed. Critically, adaptations evolve because they increase, directly or indirectly, the chances of an individual reproducing, that is, passing on genes to future generations, the ultimate goal of all living things. Thirty years after first coming to view life on Earth through an evolutionary-developmental, or evo-devo, perspective, I find it astonishing that the discoveries this perspective led to remain extremely underappreciatedby developmental scholars, clinicians, parents, and policymakers alike. While genetics has been how nature has been conceptualized for decades in nature and nurture thinking and research, evolution itself has been more or less ignored, especially with regard to the effects of early life on later development. 3. Early-life adversity accelerates development Early-life adversity should accelerate development, resulting in earlier pubertal maturation than would otherwise be expected. Because adversity can result not just in compromised functioning, but early death, accelerating sexual maturity, I theorized that adversity would have increased the chances of our ancestors successfully passing on genesdespite the fact that early puberty carries health and longevity risks. The perhaps sad truth is that evolution privileges reproduction more than health, wealth, and happiness, though these can serve as means to that end under some conditions. 4. Children differ in their susceptibility to environmental effects The future is, and always has been, uncertain, making it somewhat unpredictable. This means that developing in a manner consistent with the nurture a child experiences, whether adverse or supportive, could undermine the passing on of genes if and when the future environment proves substantially different from the one the child was prepared for. This realization led me to predict that children would vary in their developmental plasticity, that is, susceptibility to environmental influenceswhat I labeled the differential-susceptibility hypothesis. Whereas some would be strongly shaped by their early-life conditionsfor better and for worseas those emphasizing nurture have long argued, others would be far less so, as those emphasizing genetic nature have long asserted. By implication, then, those most vulnerable or susceptible to the negative effects of adversity would, at the same time, prove most susceptible to the beneficial effects of support and nurturance. Conversely, those who prove resilient in the face of adversity, so as not to succumb to its pernicious effects, would also prove less susceptible to the developmental benefits of support and nurturance. Clearly, then, the benefits and costs of being more or less developmentally plastic depend on the quality of the development context to which the child is exposed early in life. Being resilient is a benefit, for example, in the face of adversity, but a cost in the face of support and nurturance. 5. Implications of evo-devo thinking One implication of evolutionary thinking aligns with mainstream developmental thought: If we dont like the effects of adversity on development, given prevailing values, we can intervene to reduce these anticipated risks, and probably the earlier, the better. At the same time, we need to appreciate the second implication that even the most successful such efforts will fail to benefit, or benefit modestly, many childrenbecause they are less developmentally plastic. Factors that shape susceptibility to environmental influences include genetics, early temperament, and physiology. The Nature of Nurture challenges long-standing ways of thinking about human development, the role of the environment, as well as genetics, while advancing a 21st-century way of thinking about why and how early life conditions doand do notshape later life by underscoring evolution and thus natural selection, adaptation, and reproduction.
