Admir Masic: Using lessons from the past to build a better future

News Feed
Tuesday, November 12, 2024

As a teenager living in a small village in what was then Yugoslavia, Admir Masic witnessed the collapse of his home country and the outbreak of the Bosnian war. When his childhood home was destroyed by a tank, his family was forced to flee the violence, leaving their remaining possessions to enter a refugee camp in northern Croatia.It was in Croatia that Masic found what he calls his “magic.”“Chemistry really forcefully entered my life,” recalls Masic, who is now an associate professor in MIT’s Department of Civil and Environmental Engineering. “I’d leave school to go back to my refugee camp, and you could either play ping-pong or do chemistry homework, so I did a lot of homework, and I began to focus on the subject.”Masic has never let go of his magic. Long after chemistry led him out of Croatia, he’s come to understand that the past holds crucial lessons for building a better future. That’s why he started the MIT Refugee Action Hub (now MIT Emerging Talent) to provide educational opportunities to students displaced by war. It’s also what led him to study ancient materials, whose secrets he believes have potential to solve some of the modern world’s most pressing problems.“We’re leading this concept of paleo-inspired design: that there are some ideas behind these ancient materials that are useful today,” Masic says. “We should think of these materials as a source of valuable information that we can try to translate to today. These concepts have the potential to revolutionize how we think about these materials.”One key research focus for Masic is cement. His lab is working on ways to transform the ubiquitous material into a carbon sink, a medium for energy storage, and more. Part of that work involves studying ancient Roman concrete, whose self-healing properties he has helped to illuminate.At the core of each of Masic’s research endeavors is a desire to translate a better understanding of materials into improvements in how we make things around the world.“Roman concrete to me is fascinating: It’s still standing after all this time and constantly repairing,” Masic says. “It’s clear there’s something special about this material, so what is it? Can we translate part of it into modern analogues? That’s what I love about MIT. We are put in a position to do cutting-edge research and then quickly translate that research into the real world. Impact for me is everything.”Finding a purposeMasic’s family fled to Croatia in 1992, just as he was set to begin high school. Despite excellent grades, Masic was told Bosnian refugees couldn't enroll in the local school. It was only after a school psychologist advocated for Masic that he was allowed to sit in on classes as a nonmatriculating student.Masic did his best to be a ghost in the back of classrooms, silently absorbing everything he could. But in one subject he stood out. Within six months of joining the school, in January of 1993, a teacher suggested Masic compete in a local chemistry competition.“It was kind of the Olympiads of chemistry, and I won,” Masic recalls. “I literally floated onto the stage. It was this ‘Aha’ moment. I thought, ‘Oh my god, I’m good at chemistry!’”In 1994, Masic’s parents immigrated to Germany in search of a better life, but he decided to stay behind to finish high school, moving into a friend’s basement and receiving food and support from local families as well as a group of volunteers from Italy.“I just knew I had to stay,” Masic says. “With all the highs and lows of life to that point, I knew I had this talent and I had to make the most of it. I realized early on that knowledge was the one thing no one could take away from me.”Masic continued competing in chemistry competitions — and continued winning. Eventually, after a change to a national law, the high school he was attending agreed to give him a diploma. With the help of the Italian volunteers, he moved to Italy to attend the University of Turin, where he entered a five-year joint program that earned him a master’s degree in inorganic chemistry. Masic stayed at the university for his PhD, where he studied parchment, a writing material that’s been used for centuries to record some of humanity’s most sacred texts.With a classmate, Masic started a company that helped restore ancient documents. The work took him to Germany to work on a project studying the Dead Sea Scrolls, a set of manuscripts that date as far back as the third century BCE. In 2008, Masic joined the Max Planck Institute in Germany, where he also began to work with biological materials, studying water’s interaction with collagen at the nanoscale.Through that work, Masic became an expert in Raman spectroscopy, a type of chemical imaging that uses lasers to record the vibrations of molecules without leaving a trace, which he still uses to characterize materials.“Raman became a tool for me to contribute in the field of biological materials and bioinspired materials,” Masic says. “At the same time, I became the ‘Raman guy.’ It was a remarkable period for me professionally, as these tools provided unparalleled information and I published a lot of papers.”After seven years at Max Planck, Masic joined the Department of Civil and Environmental Engineering (CEE) at MIT.“At MIT, I felt I could truly be myself and define the research I wanted to do,” Masic says. “Especially in CEE, I could connect my work in heritage science and this tool, Raman spectroscopy, to tackle our society’s big challenges.”From labs to the worldRaman spectroscopy is a relatively new approach to studying cement, a material that contributes significantly to carbon dioxide emissions worldwide. At MIT, Masic has explored ways cement could be used to store carbon dioxide and act as an energy-storing supercapacitor. He has also solved ancient mysteries about the lasting strength of ancient Roman concrete, with lessons for the $400 billion cement industry today.“We really don’t think we should replace ordinary Portland cement completely, because it’s an extraordinary material that everyone knows how to work with, and industry produces so much of it. We need to introduce new functionalities into our concrete that will compensate for cement’s sustainability issues through avoided emissions,” Masic explains. “The concept we call ‘multifunctional concrete’ was inspired by our work with biological materials. Bones, for instance, sacrifice mechanical performance to be able to do things like self-healing and energy storage. That's how you should imagine construction over next 10 years or 20 years. There could be concrete columns and walls that primarily offer support but also do things like store energy and continuously repair themselves.”Masic's work across academia and industry allows him to apply his multifunctional concrete research at scale. He serves as a co-director of the MIT ec3 hub, a principal investigator within MIT Concrete Sustainability Hub, and a co-founder and advisor at the technology development company DMAT.“It’s great to be at the forefront of sustainability but also to be directly interacting with key industry players that can change the world,” Masic says. “What I appreciate about MIT is how you can engage in fundamental science and engineering while also translating that work into practical applications. The CSHub and ec3 hub are great examples of this. Industry is eager for us to develop solutions that they can help support.”And Masic will never forget where he came from. He now lives in Somerville, Massachusetts, with his wife Emina, a fellow former refugee, and their son, Benjamin, and the family shares a deep commitment to supporting displaced and underserved communities. Seven years ago, Masic founded the MIT Refugee Action Hub (ReACT), which provides computer and data science education programs for refugees and displaced communities. Today thousands of refugees apply to the program every year, and graduates have gone on to successful careers at places like Microsoft and Meta. The ReACT program was absorbed by MIT’s Emerging Talent program earlier this year to further its reach.“It’s really a life-changing experience for them,” Masic says. “It’s an amazing opportunity for MIT to nurture talented refugees around the world through this simple certification program. The more people we can involve, the more impact we will have on the lives of these truly underserved communities.”

Record numbers of plastic industry lobbyists are attending global talks that are the last chance to hammer out a treaty to cut plastic pollution across the world.The key issue at the conference will be whether caps on global plastic production will be included in the final UN treaty. Lobbyists and leading national producers are furiously arguing against any attempt to restrain the amount that can be produced, leaving the talks on a knife-edge.New analysis by the Center for International Environmental Law (CIEL) shows 220 fossil fuel and chemical industry representatives, more plastic producers than ever, are represented at the UN talks in Busan, South Korea.Taken as a group, they would be the biggest delegation at the talks, with more plastic industry lobbyists than representatives from the EU and each of its member states, (191) or the host country, South Korea, (140), according to the Centre for International Environmental Law. Their numbers overwhelm the 89 delegates from the Pacific small island developing states (PSIDs), countries which are among those suffering the most from plastic pollution.Sixteen lobbyists from the plastics industry are at the talks as part of country delegations. China, the Dominican Republic, Egypt, Finland, Iran, Kazakhstan, and Malaysia all have industry vested interests within their delegations, the analysis shows. The plastic producer representatives also outnumber delegates from the Scientists’ Coalition for an Effective Plastics Treaty by three to one.Approximately 460m tonnes of plastics are produced annually, and production is set to triple by 2060 under business-as-usual growth rates.More than 900 independent scientists have signed a declaration calling UN negotiators to agree on a comprehensive and ambitious global plastics treaty, based on robust scientific evidence, to end plastic pollution by 2040.According to the Scientists’ Declaration, the harm caused by plastic pollution cannot be prevented by improvements in waste management alone.But the world’s plastic producers have lobbied repeatedly against caps. Countries with large fossil fuel industries such as Saudi Arabia, Russia and Iran, called the “like-minded” group, have eschewed production cuts and emphasised waste management as the main solution to the crisis.Delphine Levi Alvares, the global petrochemical campaign coordinator at CIEL, said: “From the moment the gavel came down … to now, we have watched industry lobbyists surrounding the negotiations with sadly well-known tactics of obstruction, distraction, intimidation, and misinformation.“Their strategy – lifted straight from the climate negotiations playbook – is designed to preserve the financial interests of countries and companies who are putting their fossil-fuelled profits above human health, human rights, and the future of the planet.”She said the mandate for the treaty was clear: to end plastic pollution.“Ever-growing evidence from independent scientists, frontline communities, and Indigenous peoples clearly shows that this won’t be achieved without reducing plastic production. The choice is clear: our lives or their bottom line.”skip past newsletter promotionThe planet's most important stories.

Where Do Butterflies Migrate From? Clues Can Be Found in Pollen on Their Bodies

Trillions of insects move around the globe each year. Scientists are working on new ways to map those long-distance journeys

A painted lady perches on a flower. Ennio Borgato / iNaturalist CC By-SA 4.0 On a warm summer morning in Ypres, Belgium, 66-year-old Sylvain Cuvelier steps into his blooming garden with his 14-year-old granddaughter, hoping to identify and count all the fluttering butterflies. Other days, he helps scientists by netting butterfly samples. Then he records each sighting’s location using GPS, logs them in his Excel database and sometimes sends the samples to his academic colleagues, who will analyze pollen grains clinging to the insects’ bodies. Those tiny pollen grains, gathered by citizen scientists like Cuvelier, are helping researchers study a process that until now has been largely inscrutable: the migratory patterns of insects as they move around the globe over the course of multiple generations. Using pollen, scientists have been able to identify where individual butterflies began their journeys, and even infer the events that likely triggered their migration. The knowledge may help conservationists better understand some of the effects of climate change—not only on the insects themselves, but also on their migrations and the ecosystems they inhabit. A lot of insects spend their whole lives in one place. Many others migrate, as many birds do, to avoid harsh weather, to find food or to breed. Some estimates suggest that trillions of insects migrate across the globe each year, yet scientists know little about where they go or how they get there. Tracking insect migration is not as straightforward as tracking birds or mammals. With birds, “you can attach a ring to the leg or use radio tracking, and it’s easy to prove that they move from point A to B,” says Tomasz Suchan, a molecular ecologist at the Polish Academy of Sciences in Krakow. But most insects are too small for these techniques to be successful. In North America, researchers have had some success tracking monarch butterflies, known for their remarkable migration from southern Canada and the northern United States to central Mexico. In the early 1990s, the Monarch Watch citizen science initiative began tagging butterflies around the Rocky Mountains. Over two million monarchs have been tagged, with more than 19,000 recoveries reported in Mexico, where monarchs congregate to roost for the winter. This has helped biologists to track their migration routes. Butterflies without such well-defined aggregations are more difficult to track, however. For example, painted lady butterflies often appear in Europe in the fall, sometimes in great abundance. “Then they disappear, and we don’t really know where they go,” says Gerard Talavera, an entomologist at the Botanical Institute of Barcelona. Some years back, Talavera and his team realized they might be able to track the butterflies indirectly, by studying the pollen that accumulates on their bodies. Every time a butterfly visits a flower for a sip of nectar, it also picks up grains of pollen. If the researchers could identify plants from their pollen, confirm where and when the plants were blooming, and keep tracing them as the butterflies reached different geographic regions, perhaps they could follow the butterflies’ overall journey. “The method is like we put a GPS on them,” Talavera says. “Because we cannot do that, this is the closest we can go.” Pollen migratory maps The scientists were able to test the idea in 2019, when painted ladies experienced one of their sporadic population booms. In March of that year, as swarms of the butterflies appeared in the Middle East and the Mediterranean, the citizen scientists netted butterfly samples, then preserved them in an alcohol mixture and shipped them to Talavera’s lab. There, researchers isolated the pollen grains attached to the butterflies’ bodies and sequenced a particular stretch of the pollen DNA that offers a unique signature for each plant species, a process known as metabarcoding. All the while, citizen scientists kept netting butterfly samples as the population surge gradually spread through eastern, northern and western Europe over the following months, reaching southern Morocco in early November. Analyzing pollen collected from 264 butterflies from ten different countries in seven months, the researchers identified 398 different plants they could use to track the butterflies’ movements backward through the year. From this, they found that swarms of butterflies observed in Russia, Scandinavia and the Baltic countries were likely the offspring of butterflies originating from the surge in Arabia and the Middle East. This appears to have spread to Eastern Europe, then Scandinavia and then to Western Europe, resulting in a noticeable population boom in the United Kingdom, France and Spain. From there, the butterflies may have migrated to southern Morocco, likely continuing on to tropical Africa to complete their annual cycle. The pollen record even suggested a reason why painted ladies suddenly became so abundant in 2019. Butterflies collected from the eastern Mediterranean, right in the beginning of the population spike, were carrying pollen from plant species found primarily in semi-arid shrublands, grasslands and salt marshes of northern Arabia and the Middle East. Examining satellite images, the researchers noticed that from December 2018 to April 2019, those plants experienced big boosts in growth following a period of unusually heavy rainfall. That burst of growth, the researchers speculate, may have provided ideal conditions for the butterflies to feed and breed, kicking off the population explosion and leaving a ripple effect that affected many generations. Talavera and his team have used pollen signatures to track other butterfly movements as well. In 2013, for example, painted lady butterflies had been found resting on the coast of South America, in French Guiana. Painted ladies don’t normally live in South America, and it was a mystery where they had come from. A decade later, Talavera’s team sampled pollen from the still-preserved butterfly bodies and found that Guiera senegalensis, a common plant found only in sub-Saharan Africa, was by far the most common type of pollen attached to these butterflies. By analyzing coastal surveys, wind patterns, pollen and environmental conditions, they confirmed that the butterflies probably crossed the Atlantic in up to eight days’ worth of continuous flight from Africa. This finding marked the first verified instance of an insect crossing the Atlantic. “The use of pollen metabarcoding to track where each generation of butterflies comes from and how they progress through the cycle is super novel,” says Christine Merlin, a biologist at Texas A&M University and co-author of an article on the neurobiology of butterfly migration in the Annual Review of Entomology. Because it identifies individual plant species, she notes, this method promises greater precision than the standard method, isotope signature analysis, which tracks regional variations in the insects’ chemical makeup. While painted ladies serve as a model system for understanding insect migration, researchers say they are confident that this method could be suited for tracking other migrating pollinators that actively visit flowers to collect nectar, including other butterflies, syrphid flies, wasps, beetles and moths. Tracking migration routes of insects could be of growing importance in the face of changing climate, because such insects can carry fungal diseases in addition to pollen. In fact, Suchan detected many species of fungi in some butterflies. Approximately 1,000 fungi are known to affect insects, and over 19,000 can affect crops. Thus, migrating insects could potentially spread these fungal diseases across continents, posing risks to ecosystems and economies. Talavera, Suchan and colleagues hope that using pollen signatures to map changing migration patterns could help to predict where fungal disease outbreaks might occur. Cuvelier, meanwhile, hopes to continue counting butterflies with his granddaughter. Ecologists will increasingly need more “big data” to understand large-scale phenomena, he says. Without citizen scientists, he says, “it is impossible for researchers to gather such databases.” Besides, he adds, young people have more to learn from citizen science than just how to catch a butterfly. “They learn about nature,” he says, “and this fosters curiosity in the world.”Knowable Magazine is an independent journalistic endeavor from Annual Reviews.

Wildfire Smoke Linked to Increased Risk of Dementia

The particles that make up wildfire smoke may raise the risk of dementia even more than similar airborne pollutants from other sources

November 26, 20243 min readWildfire Smoke Linked to Increased Risk of DementiaThe particles that make up wildfire smoke may raise the risk of dementia even more than similar airborne pollutants from other sourcesBy Chelsea Harvey & E&E NewsA firefighter is surrounded by heavy smoke as he battles the advancing Silverado Fire fueled by Santa Ana winds at the 241 toll road and Portola Parkway on October 26, 2020 in Irvine, California. Allen J. Schaben/Los Angeles Times via Getty ImagesCLIMATEWIRE | Wildfire smoke can aggravate a variety of medical conditions, from asthma to heart disease.Now, new research adds another worry to the mix. It can elevate the risk of dementia.A study published Monday in the scientific journal JAMA Neurology, finds that long-term exposure to smoke concentrations is associated with a higher risk of dementia diagnosis over time. For every one microgram increase in wildfire pollution per cubic meter of air over the course of a three-year period, the odds of dementia diagnosis rise by about 18 percent, the study finds.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.That’s compared with each person’s baseline risk of dementia diagnosis, which remains relatively low among the general population. Still, the increased risks are large enough to pose a public health concern.The study focuses on a form of air pollution known as particulate matter — tiny, inhalable particles, with diameters of 2.5 micrometers or smaller. This kind of air pollution can originate from a variety of sources, including automobiles, industrial sources and fires.Previous studies already have suggested that particulate matter can increase the risk of dementia, among other health problems. The new research zooms in specifically on particles produced by wildfire smoke, which can have different chemical and physical properties than particles produced by other sources.The study examined medical records from more than 1 million people in Southern California from 2008 to 2019, all part of the Kaiser Permanente Southern California medical care consortium. It also analyzed air quality records from the same time period to estimate long-term pollution concentrations, including particles stemming directly from wildfire smoke.The study found that wildfire smoke increases the risk of dementia significantly more than particulate matter from other sources. There are several reasons that could be the case, the researchers say.Wildfire smoke particles tend to have higher concentrations of molecules known for toxic or inflammatory properties. And wildfire smoke tends to spike at certain times of the year, compared with other kinds of air pollution — intermittently exposing communities to extremely high pollution concentrations, which may have greater effects on their health.The study also found that certain demographics are at higher risk than others, including people with lower incomes and people of color, including Black, Hispanic and Asian communities.Low-income communities often are at higher risk of exposure to air pollution, the researchers note. Lower quality housing in these communities may allow particulate matter to infiltrate homes more easily, and residents may have less access to air filtration systems.Marginalized groups also may contend with more health challenges, in part because of systemic discrimination, compounding their risks of developing dementia later in life.“We know that climate change impacts the most vulnerable communities first and worst and we appear to see a similar signal in our data,” said Joan Casey, an environmental epidemiologist and co-author of the new study, in an email to POLITICO'S E&E News.Policymakers can take certain steps to protect these vulnerable communities, she added. They can make sure that all communications about public health are issued in multiple languages. And they can push for policies aimed at combating climate change, reducing other sources of air pollution and mitigating wildfires through strategies such as science-based controlled burns.Meanwhile, there are other questions that scientists can examine in future research.The new study looked at dementia of all kinds. But future studies can investigate whether certain types of conditions, such as Alzheimer’s disease, have stronger ties to wildfire smoke than others.The research team is also “very curious” about the effects of multiple climate hazards working together, Casey added. If wildfires happen to coincide with power outages, for instance, that could restrict the ability of many households to use air filtration systems — potentially worsening their health risks.These kinds of questions are growing more urgent as the effects of climate change worsen. Recent research has found that about a quarter of all particulate matter pollution in the United States comes from wildfire smoke. And in parts of the Western U.S., smoke is responsible for as much as half.Reprinted from E&E News with permission from POLITICO, LLC. Copyright 2024.

The Guardian view on cruise ships: a licence to pollute | Editorial

The environmental harm caused by this shapeshifting, underregulated industry must be tackledLocal pushback against cruise ships in the world’s top tourist destinations is nothing new. More than three years ago, these vast vessels were barred from Venice’s lagoon on grounds of the risk they posed to the city’s historic buildings. This summer, cruise ships in Amsterdam and Barcelona were targeted by protesters, on grounds of chemical pollution but also as part of a wider movement against overtourism (as the negative impacts of huge influxes of visitors have become known). But – as revealed this week in a series of Guardian articles, The real cost of cruises – the environmental and social impact of this fast-growing industry goes way beyond individual cities, and requires action on a global scale.The carbon emissions of a cruise are roughly double that of the equivalent flights plus a hotel stay. The industry is also responsible for a vast quantity of waste discharged directly into the sea, as well as high levels of toxic air pollution in the ports where ships are docked – usually with their engines running. Once seen as the exclusive pursuit of a minority of wealthy retired people, these holidays are now mainstream, with vast floating resorts designed and marketed for families and young adults. The largest ships have up to 20 floors and room for several thousand people. Continue reading...

Once seen as the exclusive pursuit of a minority of wealthy retired people, these holidays are now mainstream, with vast floating resorts designed and marketed for families and young adults. The largest ships have up to 20 floors and room for several thousand people.With numerous new vessels under construction, and the latest models twice the size of older ones, the industry is predicted to be worth nearly 4% of the £1.9tn global holiday market by 2028. Rightly, environmental campaigners are calling for much tougher regulations.Like aviation, shipping in general has benefited from lenient environmental and tax rules – partly due to the difficulty of deciding in which national jurisdiction, and under whose regulatory regime, their activities belong. The EU has recently agreed new penalties for those that use dirty fuel. But in the UK, shipping has not so far been included in the emissions reductions plans submitted to the United Nations – though this should change when these are renewed. The International Maritime Organization’s own carbon reduction targets do not put it on a path to net zero or even the 1.5C average temperature rise allowed for in the Paris climate agreement.As with aviation, there is an urgent need for increased international cooperation and agreement. Cruise companies should not be able to operate with lower environmental standards than other kinds of travel businesses. Their track record is poor, with many opting to fit “scrubbers” that dump emissions into the sea when they were told to reduce air pollution. In future, the ocean, as well as the air, must be protected when rules are tightened.As in other industries, the development and adoption of green technologies must become compulsory, not optional. One example is the currently patchy use of shoreside electricity, which is much lower-carbon than on-board power. The green taxes being discussed in relation to air travel should also be imposed on cruises. If this means that the industry’s plans for rapid further expansion are checked, that would be for the best. In its current form, it is not only unsustainable but causing disproportionate harm by comparison with other forms of tourism, including air travel. The environmental costs of the hedonistic visions it promotes – trips of a lifetime, and so on – must also be more effectively communicated. Trading on images of paradise while doing so much damage cannot carry on.

10 tech gifts to help lower loved ones’ stress levels

With the holiday shopping season approaching, many of us are thinking about buying the latest, most cutting-edge tech gadgets for our loved ones. I’d suggest another direction: Shopping for devices that help reduce stress and cognitive load. Let me explain what I mean. Think about how much of our technology is designed not to be calm. Your car probably has a touchscreen on the dashboard—even though it’s incredibly dangerous and stressful to use while driving. At work, there are typically several devices that are difficult to operate or repair when they break down. And when you go to bed, there’s likely one or more devices emitting a blue light that will disturb your sleep. And that’s not even getting into our smartphones! Fortunately, there are some great tech products out there that do prioritize customer well-being. They also happen to make thoughtful gifts for people in your life. Gifts for Kids Thirty percent of parents have reported high levels of stress compared to 20% of non-parents. These high levels of stress are often passed on to their kids, leaving less time for connection and play. Here are three, parent-approved devices to help reduce stress for both adults and their offspring. OK to Wake – Alarm Clock for Kids, Children’s Sleep Trainer ($39.99): OK to Wake helps kids learn regular sleep routines—thus helping parents enjoy longer sleep periods, too! The product works with gentle, color-coded lights and peaceful alarm sounds (white noise, lullabies, nature, etc.) and employs a low resolution indicator light that informs without overburdening.  Time Timer ($26.95): Time Timer is popular with teachers and parents of kids with autism and ADHD. Featuring a colored disc that gradually disappears as time elapses, it’s often used for productivity, time management, and helping children understand the very concept of time. The gradual disappearance of the colored disk provides a calm, intuitive way to show time passing, especially when placed across a room.  Yoto Player Kids Bluetooth Speaker – Plays Stories, Music, Podcasts, White Noise, Thermometer, Nightlight, Alarm Clock ($99): Offering kids a break from the algorithmic content of YouTube and other social platforms, the Yoto Player plays highly curated bedtime stories, podcasts, and white noise during bedtime. The design is notably child-friendly, with simple controls and a soft LED display that won’t interrupt sleep. The large tactile buttons (a periphery interface) enable usage in the dark without having to turn on the room lights or focus on a bright UI screen.  Gifts for Home/Personal Tech With our daily lives cluttered by distracting devices and app notifications, it’s important to consider products which help create a serene environment. 20x25x1 Air Filter by Colorfil | Color Changing Filters Designed for Cat and Dog Odor ($41.79): Our family pets are soothing; their hair and odors are not. Colorfil’s NASA-originated filter absorbs gas phase chemicals and odors from the air—and literally changes color from pink to yellow as it does so, so you don’t have to set a calendar reminder to change the filter. You can just look at it. Rather than having to check an LED meter or other abstract indicator, you know when the filter is ready to be replaced when it’s turned a bright yellow. AirThing View Plus ($249): Air quality inside the home affects human health, but is often invisible. AirThings makes air quality visible through seven sensors and visualizes them in a calm way. AirThings devices have e-ink display and a colored indicator, compressing information into a glanceable display, while allowing for a detailed view through the app. The battery life is extremely long, while the visual indicator light and e-ink display provides visual cues about air quality without intrusive audible alerts. Bose Headphones 700 – Noise Canceling Bluetooth over-ear headphones ($379.00): Seamlessly removes unwanted environmental noise while enabling you to hear music and take phone calls with perfect crisp audio. Bose uses a reductive design to remove sound from the environment, allowing you to focus on your thoughts and experience music while in noisy places, like on an airplane. Technology should always amplify the best of technology and the best of humanity. Daylight Computer ($729.00): A laptop designed to be used both outdoors and at night without disrupting circadian rhythm, the Daylight Computer (DC-1) represents a paradigm shift in computing devices. This innovative device combines the benefits of digital technology with a more human-friendly interface. And by offering a dedicated space for focused tasks like reading, writing, and note-taking, DC-1 minimizes digital distractions; days of use on a single battery charge reduce the anxiety associated with frequent charging needs. Loop Engage 2 Plus Ear Plugs ($44.95): Crowded parties and other social events can be overwhelming and distracting; these plugs filter out background noise while enabling you to focus on specific conversations you are having. (Note: These items are easy to lose; neurodivergent users might want to place them in a pouch attached to a keychain.) Loop uses the minimum amount of technology to solve the problem, resulting in a small solution that’s easier to use than a squishy foam earplug. NOCO Boost Plus GB40 1000A UltraSafe Car Battery Jump Starter ($99.95): Jumper cables are a necessary but intimidating part of the diving experience. (Where do I put the connectors again? Will I destroy my battery in the process?) I recently used one of these when my car lost its battery life on a road trip. Fortunately, a friend had brought hers, bringing my car back to life long enough to drive to an AutoZone. This model is designed to make a jump start simple, safe, and easy, with clear indicators and instructions on the front, so you can jumpstart your car without fear of misuse. Unpluq (Price varies based on subscription): A simple keychain tag with NFC connectivity, Unpluq “locks” selected apps for a designated time, preventing access unless they’re physically unlocked—giving users a concrete, customizable means to manage their digital habits while maintaining tangible interfaces. With an average screen time reduction of one hour and 22 minutes per day, Unpluq demonstrates lasting behavioral change. True to its intent, Unpluq also requires minimal attention, using a physical key to manage phone access, requiring nominal cognitive effort to engage or disengage from digital distractions. The explosive growth of social media and smartphones, now further amplified by AI, has totally overwhelmed us. But there’s a better, more humane approach to tech that we desperately need now. A good place to start is in our shopping and gift-giving habits.
