I have a theory that every person is constantly pulled—almost by some invisible magnetic force—to one particular place that feels safe and magical and misty with nostalgia. Maybe it’s the gazebo where you got married or the garage where you started your first band. It feels like, if you just get back there, the white noise will gently dim and life will briefly make sense again.

For me, that place is the flat part of a nondescript boulder positioned opposite a 15-foot waterfall with a very disturbing name.

I first visited Dog Slaughter Falls as a middle-schooler, and I was adamantly not stoked about the idea. At that time, I was a shy, somewhat artsy kid searching for meaning in the conservative Bible Belt town of Williamsburg, Kentucky. I was still a lump of unformed human clay—largely consumed by rock music and entirely disinterested in matters relating to the shoebox church my parents drug me to each Sunday. But I was also a Certified Strait-Laced Good Boy, so I entertained my mom’s pitch: an afternoon of hiking with a group of older folks, guided by the botanical knowledge of a nature-loving priest.

Turns out this was more of a demand than an invitation, so I invited my friend Tyler along for this frolic from hell—at least I could suffer alongside a kindred spirit. I wasn’t expecting to enjoy this foolishness, let alone have it alter my brain chemistry in a real, profound way. But life is strange.


Dog Slaughter Falls is located within Daniel Boone National Forest, which sprawls across 708,000 acres and 21 counties in Eastern Kentucky. But even if you’re not from the area, you still might be familiar with its star attraction: the massive and majestic Cumberland Falls, one of the only places on Earth where you can regularly see a “lunar rainbow”—a phenomenon created by moonlight rather than sunlight.

Visiting the so-called “Niagara of the South” was a staple of my formative years. Outside of buying scratch-off tickets and meandering around Wal Mart, there really wasn’t much to do in Williamsburg, so we frequently made the 20- or 30-minute trip up to Corbin, windows rolled down, cranking whatever new indie-rock album we were obsessed with. I vividly remember road-testing Modest Mouse’s Good News for People Who Love Bad News as we navigated those windy roads late at night, my senses heightened by the darkness and perpetual motion. One time, my friend Calep showed up with a burned copy of Brand New’s The Devil and God Are Raging Inside Me—hearing “Jesus Christ” in that setting felt legitimately cinematic. During that era, my friend Rishi and I, having borrowed an unwieldy camcorder from a classmate, trekked down to the Falls’ beach area and, utilizing a form of forced perspective, staged a tragic suicide scene from our (still-unfinished) amateur film It’s Great to Be in Cincinnati.

I’ve always felt a restorative force at Cumberland Falls, and I know a lot of people who feel similarly. Also, as a restless kid with big-city dreams, I felt trapped in my hometown, but living near the Falls was a badge of honor—something I could name-drop to a stranger in conversation and feel vaguely proud. But…it was also a state park swarmed with tourists—it belonged to everyone. Dog Slaughter, on the other hand, felt like a secret.


Let’s talk about the name—or, more specifically, how little we know about it. According to Kentucky State Parks, the origin of the grisly “Dog Slaughter” moniker “remains a mystery,” despite regular questions from visitors. The Independent Herald, a newspaper located in nearby Oneida, Tennessee, has a couple theories: One, which I also heard as a kid, is that “unwanted pets were once killed there.” Yeah, pretty horrifying! Another: “that hunting dogs were once slain by a beast unknown at this site—maybe a wolf, maybe a bear … some even say Bigfoot.” (This also calls to mind the local legend: the Mulberry Black Thing, but we’ll save that one for another day.)

I reached out to some local experts, thinking maybe, just maybe, they knew a deeper truth obscured from the general public. The responses varied.

Jehan Abuzour, parks program services supervisor (previously park naturalist) at Cumberland Falls State Resort Park since September 2023, is aware of two stories. (Dog Slaughter is technically not located on park property, though there is a connecting trail.) “I’ve heard that [frontiersman] Daniel Boone wrote in his journal about how he brought his hunting dogs with him in the area and they chased a raccoon, and the raccoon went under the lip of the Dog Slaughter Falls waterfall,” she says. “The hunting dogs didn’t see the cliff, and they went over it and died. Daniel Boone supposedly named it Dog Slaughter Falls. The other story is pretty broad: Basically there was a group of early settlers of Kentucky, and they encountered a pack of wild dogs out there at the falls.“

Pamela Gibson, former trails maintenance supervisor and volunteer coordinator at Cumberland Falls State Park, calls Dog Slaughter a “local landmark”—but with a name that invites a lot of complaints. “According to what the Park had written, Dog Slaughter Falls was named for an incident that happened before the area was very populated,” she says. “Story goes, the locals were out hunting [raccoons] in the area using dogs. The dogs had the coons pinned in the creek, when the raccoon got one of the dogs in the water, drowning several dogs. Everyone knows dogs do not stand a chance with a raccoon in the water.”

Connie Howard has been hiking there for over four decades and lives in a cabin near the trailhead. (Speaking of which, she’s had “many hikers who have gotten lost knock on [her] door during the night.”) But she doesn’t think “anyone is sure” how Dog Slaughter got its name. “The old timers, long deceased, told me it was because of hunting dogs being killed by a mysterious beast that lived in the area,” she says. “Who knows?”

The whole “slaughter” branding may intimidate some people from venturing out there—notably, on the horror front, it even inspired a Creepypasta involving a camping trip, a little girl’s diary, and a mysterious creature. But the hike, at least in my travels, has been the opposite of unsettling. Then again, I’ve always been out there with at least one other person—or, in the case of my first time, with a large group of people I mostly wanted to avoid.


Tyler and I jostled in my family’s minivan as it slowly rumbled roughly three miles down a gravel road. I remember Shania Twain’s country-pop hit “Man! I Feel Like a Woman” playing on the radio, its signal shifting more to static with each bump—it felt like an omen, but I wasn’t sure what kind. We arrived at an unmarked pull-off area overseen by a huge rock, and all of the churchgoers piled out of their cars and onto the trail, with Tyler and I shuffling to the rear. Sensing our awkwardness, a rowdy (and, frankly, somewhat frightening) 50-something man we’ll call Jerry decided to become our unofficial tour guide.

As the rest of the hikers moseyed along the shady, ultra-green, 2.5-mile path, stopping periodically to gaze at flowers, our out-of-nowhere buddy countered that peacefulness with lots of antics. Multiple times, he shouted caveman gibberish with a cavernous roar; at one point, he frantically jumped on a downed tree that crossed along Dog Slaughter Creek, almost daring it not to break; and, in what remains the funniest thing I’ve ever seen, he tripped over a rock, his body soaring a Superman-like free-fall before smoothly skidding into fresh mud. He arose, wiped his eyes, and shouted manically. Jerry was having himself a day.

Meanwhile, I was falling in love—even if I was embarrassed to admit it at the time. Despite the chaos, I felt serene among the fizzy creek sounds and creeping moss and cold rocks. During a picnic lunch, we all gathered on that massive boulder, a short swim away from the base of the falls, and I was hypnotized by the unending rush of water. “This is always just…out here,” I thought. And I’ve dusted off that disbelief every time I’ve returned over the following two-plus decades, often joined by my wife (Jen) and our Brittany Spaniels (Tegan and the late Gabriel).

I’m an anxious, depressive person by nature—I have trouble slowing down, living in the now, savoring the good moments before they slip through my fingers. But I crave the zen-like tranquility I feel at Dog Slaughter. I always leave feeling blissfully still—as if I’ve stopped the flood, even momentarily, to gaze at one outside myself.

  • Kenyan teens create award-winning, affordable car exhaust filters made with corn cobs and algae
    Photo credit: @theearthprize on Instagram/CanvaTwo 17-year-olds made a device that is helping reduce air pollution in Kenya.

    When Fredrick Njoroge Kariuki of Kenya turned 12 in 2021, he experienced incredible difficulty breathing. Doctors diagnosed him with bronchitis, explaining that his coughing and breathing issues were connected to the thick layers of exhaust fumes emitted by vehicles in the area. Five years later, the teenager teamed up with his classmate Miron Onsarigo to create an award-winning, inexpensive filter made with agricultural waste.

    While air pollution is a global concern, it is particularly an issue in Kenya. A 2024 study found that Nairobi, Kenya’s capital, had 3.7 times higher levels of particulate air pollution than the World Health Organization’s guidelines. This doesn’t just contribute to illness like Kariuki’s bronchitis. Experts estimate that the country’s air pollution is responsible for 400 to 1,400 premature deaths in Nairobi each year.

    The global environment issue was personal

    Both teens were hardened in their resolve to tackle this air pollution problem largely caused by the matatus (shared minibuses) and boda bodas (motorcycle taxis) common in urban areas.

    “The problem of air pollution was very personal to us, and that is why we started thinking about coming up with a solution,” Kariuki told Mongabay. “It was a passion before it became a project.”

    “I did not choose this problem. It chose me,” Kariuki said to Daily Nation. “Growing up in Naivasha, my bronchitis got so bad that I stopped thinking of air pollution as an environmental issue and saw it as something being committed against us.”

    “Seeing people get sick as a result of fumes from vehicles has become normal back home in Kisumu County. The ‘normal’ did not feel right to me. I wanted to do something about it,” added Onsarigo.

    Using waste products to clean the air

    With time, intelligence, and hard work, Kariuki and Onsarigo created the HewaSafi vehicle exhaust filter. The HewaSafi, which means “clean air” in Swahili, was made using locally sourced agricultural waste. The entire mechanism is made from steel mesh, copper, corn cobs, coconut shells, recycled batteries, and algae. All of these components help further filter out particles in the air straight from the exhaust pipe.

    The results of the HewaSafi were impressive. The device reduced particulate matter in the air by 93.3%. The HewaSafi also reduced carbon monoxide by 42% and absorbed 21.4% of CO2 that would otherwise be released into the atmosphere.

    Since the device was made using waste products, the HewaSafi manufacturing cost is around $126. By comparison, conventional filters of this sort typically cost around $390. So, not only is this filter effective, it’s cheap enough for more people to use.

    You breathe it every day. But how often do you think about it? Air pollution affects where we live, how we move, and who gets left behind.

    A prize that leads to further opportunity

    The ingenuity of these two 17-year-olds won them the 2026 Earth Prize for Africa. They received $12,500 for their regional win and global attention to the HewaSafi.

    The teens hope to use the prize money and attention to further develop the HewaSafi. Using connections made through the Earth Prize, they aim to start a full line of emission control products. While they want to work with people with different budgets, their main target is to specifically cater HewaSafi filters toward public transportation vehicles.

  • The drawer problem: Why so many of us can’t let go of our old electronics, and what we can do about it
    Photo credit: Peter Dazeley/Photodisc via Getty ImagesThis look familiar?

    Think about the last smartphone, tablet or smartwatch you stopped using. Odds are it is not in a recycling bin or a new owner’s hands; it is sitting in a drawer.

    From our survey of 4,000 American consumers, we found the single most common thing people did with a device they were finished with was nothing at all: 39% simply stored it. Recycling and reselling, outcomes better for the environment, each accounted for only about 1 in 10 devices. Throwing devices in the trash claimed another 9%.

    What people do with old electronics

    Funded by the National Science Foundation, our multidisciplinary team blended our expertise in causal inferencesustainability and cybersecurity, to work on the tangled question of what people do with their consumer electronics when they’re done using them. We used statistical models to connect what people say – that is, their stated knowledge and attitudes – to what they actually did.

    Why the drawer wins

    Two main forces keep devices in the drawer. The first is anxiety about data. People who worried that recycling or reselling a device would compromise their data were 14% and 9% more likely to store it instead.

    The second force is simply not knowing how to. People who did not know where to recycle were 10% more likely to hold onto a device, and many also kept old gadgets as a perceived data backup.

    Recycling and reselling electronics are a lot easier than a lot of people think. In the U.S., the national chain Best Buy accepts devices for recycling; reselling online is convenient with vendors such as Back Market and Gazelle.

    Just be sure to wipe data before parting with a phone or computer. Also, remove the device from your account, for instance with Apple or Android. Unless you do, the device stays locked to you, and no one else can use it.

    We also compared what people intended to do with what they had actually done. This led to a telling detail: Data security worries led to people storing devices at a greater rate than they said they intended to.

    In other words, the fear of leaking personal data kicks in only when someone is facing the real decision of whether to hand off their device to a recycler or secondhand buyer.

    Getting at why people don’t recycle

    Researchers have long studied why people do or don’t recycle electronics: Convenience, awareness and incentives showed up as affecting the decision. But prior work examined recycling as the only option.

    Instead of considering the issue as a yes-or-no vote on recycling, we treat it as a comparison between different options: Storing, reselling, donating, trading in, recycling and throwing away the device in the trash. When modeling this way, trade-offs became visible.

    Knowing where to recycle, for instance, made recycling 47% more likely, but it also pulled people away from reselling, which is often the more environmentally friendly choice. You can explore the survey results in our interactive dashboards.

    Getting people to let go

    Storage is the worst of both worlds: A device sitting unused for years loses its resale value, and erasing its data only gets harder over time. The good news is that the main barriers – data concerns and not knowing where to turn – can be addressed with better information.

    We are experimenting with information interventions that walk people through their options, including how to securely wipe their data. We are testing nudges with randomized, controlled trials to test what leads people to give their old electronics a second life.

    It might be a good time to remember what old devices you’re holding onto and revisit your reasons for not letting go of them.

  • Solar-powered boat feasts on trash and could solve the ocean’s plastic waste problem
    Photo credit: Ocean Cleanup on YouTubeThe Interceptor boat-barge could significantly clean our waters.

    Our oceans have a plastic problem. While it’s difficult to put a 100% accurate number on it, scientists estimated about 4.8 to 12.7 million metric tons of plastic waste entered the ocean in 2010 alone according to the journal Science. This issue has caused scientists and engineers to create a boat-barge in Los Angeles that skims the oceans to gobble up the plastic we leave behind.

    Devised by the non-profit Ocean Cleanup organization, the garbage-gulping Interceptor boat-barge is actually a smaller platform nestled within a larger boat. A floating barrier moves collected trash into the device onto a conveyor belt. An automatic shuttle then collects the trash from the conveyor to send it to a separate barge where there are six dumpsters to hold it. The solar-powered system can hold up to 20,000 lbs. of garbage. The trash is then separated into different categories (plastics, metal, etc.) so they can be disposed of responsibly.

    Catching ocean trash from the source

    Ocean Cleanup hopes to make a dent cleaning the Great Pacific Garbage Patch in the Pacific Ocean. However, they decided to first attack the plastic ocean problem at its source: rivers. When it rains, a lot of trash from the hills and valleys washes down into the nearest river. While there is significant ocean trash taken from beaches, they have found that the lion’s share of garbage that floats into our oceans actually comes from rivers and tributaries that lead into it. Essentially, the plan is to get ocean trash before it even enters the ocean.

    “We have to turn the faucet off before we can scoop the ocean, or else all we’re doing is taking out legacy trash to replace it with new trash,” James Patterson, the operations manager of Ocean Cleanup said to The Guardian. “Before you can clean out the Great Pacific Garbage Patch, you really need to turn off the source.”

    How the Interceptor is helping Los Angeles and beyond

    There is an Interceptor already doing its work at the mouth of Ballona Creek in Culver City, California. Since 2025, the Interceptor has prevented 143,710 lbs. of trash from entering the ocean via the creek. As a bonus, the Interceptor’s trash sweeping has lowered government budgets for beach grooming. Since there is less trash, the beach doesn’t need to be cleaned as often.

    There are two more Interceptors planned to be at the mouths of the San Gabriel River and the Los Angeles River. This can help clean up the rivers for the upcoming 2028 Summer Olympics for aquatic events.

    There are currently 21 Interceptor systems throughout the globe. Countries using them include Indonesia, Vietnam, Jamaica, Guatemala, the Dominican Republic, and Malaysia.

    If this is an issue that speaks to you, you can help even if you don’t live near an ocean. There may be a nearby river or creek that could benefit from volunteer cleanups. Do some research to find an organization near you to volunteer. If you can’t locate one, groups like River Cleanup can help you organize your own group. Much like how a small drop contributes to a large ocean, a small pick-up can make a big difference.
