Scientists tested 3 popular bottled water brands for nanoplastics using new tech, and yikes

The results were alarming—an average of 240,000 nanoplastics per 1 liter bottle—but what does it mean for our health?

Columbia University researchers tested bottled water for nanoplastics and found hundreds of thousands of them.

Evian, Fiji, Voss, SmartWater, Aquafina, Dasani—it's impressive how many brands we have for something humans have been consuming for millennia. Despite years of studies showing that bottled water is no safer to drink than tap water, Americans are more consuming more bottled water than ever, to the tune of billions of dollars in bottled water sales.

People cite convenience and taste in addition to perceived safety for reasons they prefer bottle to tap, but the fear factor surrounding tap water is still a driving force. It doesn't help when emergencies like floods cause tap water contamination or when investigations reveal issues with lead pipes in some communities, but municipal water supplies are tested regularly, and in the vast majority of the U.S., you can safely grab a glass of water from a tap.


And now, a new study on nanoplastics found in three popular bottled water brands is throwing more data into the bottled vs. tap water choice

Researchers from Columbia University used a new laser-guided technology to detect nanoplastics that had previously evaded detection due to their miniscule size.

The new technology can detect, count and analyze and chemical structure of nanoparticles, and they found seven different major types of plastic: polyamide, polypropylene, polyethylene, polymethyl methacrylate, polyvinyl chloride, polystyrene, and polyethylene terephthalate.

In contrast to a 2018 study that found around 300 plastic particles in an average liter of bottled water, the study published in the journal Proceedings of the National Academy of Sciences in January of 2024 found 240,000 nanoplastic particles per liter bottle on average between the three brands studied. (The name of the brands were not indicated in the study.)

As opposed to microplastics, nanoplastics are too small to be seen by microscope. Their size is exactly why experts are concerned about them, as they are small enough to invade human cells and potentially disrupt cellular processes.

“Micro and nanoplastics have been found in the human placenta at this point. They’ve been found in human lung tissues. They’ve been found in human feces; they’ve been found in human blood,” study coauthor Phoebe Stapleton, associate professor of pharmacology and toxicology at Rutgers University’s Ernest Mario School of Pharmacy told CNN Health,

We know that nanoplastics are making their way into our bodies. We just don't have enough research yet on what that means for our health, and we still have more questions than answers. How many nanoplastics does it take to do damage and/or cause disease? What kinds of damage or disease might they cause? Is whatever effect they might have cumulative? We simply don't have answers to these questions yet.

That's not to say there's no cause for concern.

We do know that certain levels of microplastic exposure have been shown to adversely affect the viability of cells. Nanoplastics are even smaller—does that mean they are more likely to cause cellular damage? Science is still working that out.

According to Dr. Sara Benedé of the Spanish National Research Council’s Institute of Food Science Research, it's not just the plastics themselves that might cause damage, but what they may bring along with them. “[Microparticles and nanoparticles] have the ability to bind all kinds of compounds when they come into contact with fluids, thus acting as carriers of all kinds of substances including environmental pollutants, toxins, antibiotics, or microorganisms,” Dr. Benedé told Medical News Today.

Where is this plastic in water coming from?

This study focused on bottled water, which is almost always packaged in plastic. The filters used to filter the water before bottling are also frequently made from plastic.

Is it possible that some of these nanoplastics were already present in the water from their original sources? Again, research is always evolving on this front, but microplastics have been detected in lakes, streams and other freshwater sources, so it's not a big stretch to imagine that nanoplastics may be making their way into freshwater ecosystems as well. However, microplastics are found at much higher levels in bottled water than tap water, so it's also not a stretch to assume that most of the nanoplastics are likely coming from the bottling process and packaging rather than from freshwater sources.

The reality is, though, we simply don't know yet.

“Based on other studies we expected most of the microplastics in bottled water would come from leakage of the plastic bottle itself, which is typically made of PET (polyethylene terephthalate) plastic,” lead author Naixin Qian, a doctoral student in chemistry at Columbia University, told CNN Health. “However, we found there’s actually many diverse types of plastics in a bottle of water, and that different plastic types have different size distributions. The PET particles were larger, while others were down to 200 nanometers, which is much, much smaller.”

We need to drink water, and we need to drink safe water. At this point, we have plenty of environmental reasons for avoiding bottled water unless absolutely necessary and opting for tap water instead. Even if there's still more research to be done, the presence of hundreds of thousands of nanoplastics in bottled water might just be another reason to make the switch.

Left: Teacher Diane Tirado. Right: The note she left for students after being fired.

If you're of the mind that kids today are being coddled and not properly prepared for the real world, well, you might want to buckle up for this one. The story out of a public school in Florida has parents and teachers alike up in arms.

A Florida teacher was fired for giving her students zeros for missing assignments. Diane Tirado has been a teacher for years. Most recently, she was an eighth-grade history teacher at Westgate K-8 School in Port St. Lucie, Florida. Diane recently gave her students two weeks to complete an Explorer notebook project, but several students simply didn't hand it in. Since there was zero work done, Diane gave them zeros.

She got fired for it.

The elementary school has a rule called the “no zero policy."

The lowest possible grade that teachers can give students is a 50, even if they don't turn anything in. That means that an extremely poor completed assignment is worth the same number of points as no assignment at all.

Hardly seems fair, right? Westgate is far from the only school that has such a policy, however.

It's a rule that Diane, unsurprisingly, does not agree with. After she was fired for disobeying, she left her students a charming goodbye message on the whiteboard.

"Bye kids. Mrs. Tirado loves you and wishes you the best in life. I have been fired for refusing to give you a 50 percent for not handing anything in. Love, Mrs. Tirado"

The scale, as outlined by the school, reads as follows:

A = 90 to 100
B = 80 to 89
C = 70-79
D = 60-69
F = 50-59

Diane later shared the story on Facebook, hoping to spread awareness about the school's policy.

“A grade in Mrs. Tirado's class is earned," she said.

“I'm so upset because we have a nation of kids that are expecting to get paid and live their life just for showing up and it's not real."

Diane's post has gone viral, and most commenters agree with her position – it's not fair to hand out grades for work that doesn't exist.

No zero policies are common in many schools, and teachers notoriouslyhate them. But it's at least worth considering why they exist. Some educators say it's because when a student earns a zero, it's very difficult for them to ever recover their grade in that class. In other words, it may be too harsh. Others argue that, if you don't want a zero, don't turn in nothing! Getting an earned-zero is a great way to learn to at least try.

A follow up statement from the school stated: "Ms. Tirado was released from her duties as an instructor because her performance was deemed sub-standard and her interactions with students, staff, and parents lacked professionalism and created a toxic culture on the school’s campus. ... During her brief time of employment at West Gate, the school fielded numerous student and parent complaints as well as concerns from colleagues. Based on new information shared with school administrators, an investigation of possible physical abuse is underway."

However, school representatives did not deny the existence of the no zero policy, and Tirado claims the school engaged in a smear campaign after she became a "whistleblower" on their policies. She's currently considering legal action against the district.

Still, the debate over the grading policy rages on.

“The reason I took on this fight was because it was ridiculous. Teaching should not be this hard," Diane said.

A musical mashup that no one expects but people can't get enough of.

We've seen a lot of musical mashups and genre-bending performances over the years, and just when it seems we may have seen it all, someone comes up with something fresh and surprising. We saw it with Irish brothers step dancing to Beyonce's country hit. We saw it with an Indian-Scottish wedding march. We've seen it with a South African musician's beats combined with cat's meows, yowls, and growls.

And now we're seeing it with musical theater and acoustic folk music. Musician C. Scott asked what would happen if Phantom of the Opera were sung by a folk singer, and then proceeded to show us in the most down home, sitting-on-the-porch-at-sunset way. And, in the most delightfully weird way, it works.

Check out his version of "Wishing You Were Somehow Here Again" from Phantom of the Opera:

People were blown away by how much they loved it, with some even preferring it to the original.

"SIR. SIR. I was NOT expecting to be absolutely gobsmacked on a Thursday evening. This is incredible. ❤️"

" Inject it into my veins. I wanna buy this."

"I need all my Broadway shows like this! ❤️"

"Whyyyy does this work???? Loll"

"I like this better actually?"

One person called it "Phantom of the Grand Ole Opry," and another called it "Portland of the Opera," both of which truly sum it up.

After C. Scott shared another Phantom song ("All I Ask of You"), actors who had actually performed in the musical weighed in with their thoughts.

"Oooo as one of the men who has gotten to play this role, I LOVE THIS and would absolutely love to see this version!!!"

"As a former Phantom on the national tour, I approve of this message."

"I played Christine in Phantom for a decade and this is greatest thing I’ve ever heard! Wow! Thank you for this glorious reinvention!"

"As a cast member of the Broadway production, I gotta say… THIS IS 🔥🔥🔥🔥"

Clearly, C. Scott hit a nerve with the musical theater kids and the folk music lovers, but he didn't stop there. He moved on from Phantom and sang "I Dreamed a Dream" from Les Miserables, fully solidifying the unique genre.

It's not just that he put an Appalachian spin on Broadway; it's that his guitar playing and singing are genuinely enjoyable to listen to. Hearing these songs sung in a different way also highlight the lyrics in a whole new light, prompting us to think about them more deeply, or at least hear them from a different angle

Along with requests for certain songs—"Empty Chairs at Empty Tables" has been a repeated refrain—people have started pushing C. Scott for an album of musical-theaters-standards-turned-folk songs.

"Honestly. You could do a folk rendition of broadway classics and moderns. I’d buy that album. For sure."

"The genre I did not know I needed! Not to seem greedy but can we please have a whole album?"

"Better see an album come out for this."

"My wife would buy every one of your albums."

Ask and ye shall receive. C. Scott shared a message with his followers announcing his plans.

"From the bottom of my heart, thank you so, so much for all the support I've been getting for these covers that I've been doing, these Broadway covers," he said. "It's really kind of surprised me how interested y'all are in them, and it's really, really exciting. You seem to enjoy listening to them as much as I enjoy making them, so thank you so much for that."

He shared that he'd been talking to his recording studio buddy to help him put together an EP. He said they have some musicians who will be coming on to make a three or four-song EP. (If you love this and want to help with the costs of production, you can find his Venmo here.) So, be on the lookout for that.

Pets

Four guys asked their new neighbor if they could walk her dog. Then the dog wrote back.

"If you ever get bored, we are more than happy to look after him/her."

A black dog and a note form "the boys from number 23."

If you've lived your whole life with a dog, a home has to feel pretty empty without one. Your heart has to feel like there's something missing as well. When Jack McCrossan, originally from Scotland, moved to Bristol, England with his three friends, they were bummed out to learn that their landlord didn't allow dogs.

So when they saw a beautiful black Sheprador (a German Sheppard Lab mix) in their neighbor's window, they knew that had to become buddies with her. They wrote the dog's owner, Sarah Tolman, a letter asking to arrange a play date with the dog. "If you ever need someone to walk him/her, we will gladly do so," they wrote.

"If you ever get bored (we know you never will, but we can dream), we are more than happy to look after him/her. If you want to come over and bring him/her to brighten our day, you are more than welcome. If you want to walk past our balcony windows so we can see him/her, please do," the letter continued.


"We hope this doesn't come too strong, but our landlord won't allow pets, and we've all grown up with animals. The adult life is a struggle without one," they wrote. "Yours sincerely, The boys from number 23," the letter concluded.

Soon after, the boys in 23 received a response from the dog herself, Stevie Ticks, accepting the offer. However, it may have been written by her human, Sarah Tolman. In the letter, Stevie shares a bit about herself, saying she's two years and four months old, was adopted in Cyprus, and that she's "very friendly and full of beans." (The boys shouldn't worry about a gassy hound, in England, "full of beans" means lively.)


"I love meeting new people and it would be great if we can be friends. I must warn you that the price of my friendship is 5 x ball throws a day and belly scratches whenever I demand them," the letter continued. A few days later, the boys got to meet Stevie. "Meeting Stevie was great!" McCrossan told Buzzfeed. "She was definitely as energetic as described. We got to take her for a walk and she wouldn't stop running!"

Tolman thought the boys' letter was a fantastic gesture in an era where, quote often, neighbors are strangers. "In a day and age where people don't really know or speak to their neighbors, it was really nice for them to break down that barrier," she said. After the story went viral, she saw it as an opportunity for people to share their love of dogs with the world. "My mother and I are amazed at all the love we've received from around the world these past few days," Tolman wrote as Stevie. "If you have a doggo in your life, share that love with those around you."

A lot has changed in the past 6 years since this story warmed hearts around the globe. The boys have since moved away, but as of September 2024, Stevie is around 8 years old and still doing well. Her keeper and Sarah's partner, Chris Bowley, shared an update on Instagram. "[The boys] sadly moved out of Bristol. However, we have always tried to keep the ethos going of Stevie having as many friends and meetups as possible," Bowley wrote.

It's not just nostalgia. Our childhood cartoons were better.

Nobody needs convincing that the cartoons of yesteryear just hit different. They are miles away from the noisy, uber colorful, fast-paced (read: overstimulating) shows that a kid might watch today. And, it turns out, that they might just be superior for getting kids to actually relax.

This was a discovery made by one mom (Lauren, aka @mamasandmesses) when she introduced her toddler to old school shows like Bear and the Big Blue House, Arthur, Dragon Tales, and more. Her grand experiment led to some pretty fascinating results.

For one thing, she noted while her child enjoyed watching these programs, there was no adverse reaction when she turned them off. “He didn’t fight me or get upset, he just went back to playing!”

But perhaps even more importantly, she noticed that his sleep improved. That’s right, parents with tough-to-put-to-bed kiddos, listen up.

Lauren attributed this to the fact that, generally speaking, 90s shows had much lower stimulation, but also more heavily focused helpful lessons and creative exploration. Sure, there are still shows that do that, like Bluey, but nowadays having a slower pace, softer color palette, and more subdued soundtrack is certainly no longer the standard.

In fact, experts have long warned against the drug-like “dopamine rush” of contemporary cartoons, which might offer endless amounts of quick entertainment, but don’t allow for kids to actually process what they’re watching, and continuously leave them wanting more. Almost like the creators of these shows are more interested in getting views and earning money than by actually serving a need? Nah, that’s crazy.

Adding to the problem is that, now, anything with a screen can suddenly turn into a TV. This heightened accessibility means that a once seemingly innocent, totally mundane pastime can turn into a problem. But luckily, parents can control what their children are seeing their TVs, tablets, phones, and whatever else. Since many 90s classics are available to stream, these less-stimulating yet more-engaging shows are always on hand, and Lauren was kind enough to share a master list:

📺 Bear in the Big Blue House – Disney+

📺 Out of the Box – Disney+

📺 Little Bear – Paramount+

📺 Franklin – Prime or YouTube

📺 Arthur – PBS Kids or Hulu

📺 Rolie Polie Olie – Prime

📺 Clifford – Prime

📺 Magic School Bus – Netflix

📺 Berenstain Bears – Prime

📺 Dragon Tales – Prime

📺 Wishbone – YouTube

📺 Mr. Rogers’ Neighborhood – PBS Kids, Hulu, or Prime

As a bonus: something kinda from our childhood (the book, anyway) but a newer show

📺 If You Give A Mouse a Cookie – Prime

- YouTubewww.youtube.com

Besides the fact that these shows might overall be better for our kids, there’s also something special about rewatching these beloved shows from our childhood, and seeing the positive effects that they continue to bestow. It’s one of those times where we can say, “They didn’t make them like they used to!” and it truly carries some weight. So, you know, bragging rights.

High-octane kid’s shows probably aren’t going anywhere, but it’s nice to know that we have options when it’s time to really wind down and soothe little nervous systems.

Now, if you’ll excuse me, there are a few seasons of Arthur calling my name…

Sabrina (@sabfortony) eats the last meal her husband Tony cooked for her before he passed away.

Losing someone you love never gets easier, and the grief process comes in waves. One way TikToker Sabrina (@sabfortony) got to honor her husband Tony's memory was by eating the last meal he cooked for her the day he died.

Sabrina shared the emotional video with her followers on TikTok. "I’ll forever miss Tony’s cooking," she captioned the video, adding, "Let's eat my late husband's last meal together."

@sabfortony

i’ll forever miss tony’s cooking #lastmeal #moving #griefjourney #healingjourney #lifeafterloss #partnerloss

It begins with Sabrina holding a small quart-sized plastic container up to the camera, and she begins to describe its significance. "I have something very special here. The day that Tony passed away, I really wanted curry–and I wanted Japanese curry, so I asked Tony to make me some and he did," she says. "I ended up freezing it because I wanted to preserve it forever. But because I'm moving out of state, I need to eat this. I know some of you might think that is crazy cuz it's been over two years. Tony was the primary cook of our family, and so anytime I was craving something he would make it for me. That was one of the many ways that he showed love for me."

She then heats up the bowl of curry so that it is "scalding hot," noting that it has "turned to mush" before she tastes it. "Thank you Tony for my last meal in this home," she says. "And my apologies that I am raw-dogging this–I don't have any rice."

Sabrina's emotional video got an overwhelming response in the comments.

"🥺🥺🥺 last meal in the home you shared together 🥺," one wrote, and Sabrina replied, "😭 he knew i needed it 💗."

Another wrote, "Just thinking how his hands cut the ingredients and his heart cooked it with love made me sob. What a beautiful moment." Sabrina responded, "so much love 😭😭 it’s so special."

Another viewer commented, "He’s sending you off to the next chapter with love 🥹❤️," and Sabrina replied, "so true 😭 i’m so thankful for that."

Other viewers shared their personal stories of how food connected them with lost loved ones. "I kept my mom’s kimchi for as long as I could. I ate it the night I got my heartbroken and felt so comforted. Food is such a strong connection to those we know we can’t hold anymore," one shared. Sabrina replied, "food really is such a beautiful way to connect with people 😭 i’m glad your moms kimchi was a source of comfort 💗 she is with you always."

Another viewer shared, "When my grandmother knew she was sick, before she told anybody, she baked, cooked, froze, and canned until the pantry and freezer were full. After she died my grandfather ate her meals for a year." Sabrina responded, "what a beautiful soul 💗 caring for the people she loves."
