Living in the future has some amazing perks.

A French tech company is rolling out a new device that allows wheelchair-bound people to walk again. It looks like something straight out of a science fiction movie, but the phenomenal benefit it provides is very, very real.

The company, Wandercraft, calls it the Atalante X. It acts like an exoskeleton, fitting around both legs and the back of the spine. Twelve motors make up the robot appendages (six at the hips, two at the knees, and four at the ankles), which helps make more natural movement.

Each motor receives a signal every millisecond from both a user-controlled remote and a sensor that detects upper body movement. This cutting-edge technology allows, for the first time ever, the freedom of hands-free motion.

Alexandre Boulanger, one of Wandercraft’s creators, regarded exoskeletons as “the revolution of the future for people with reduced mobility. They help users to regain a social life through as simple an act as being able to stand up and talk with others face-to-face.”

So far, users seem to agree.

In an interview with Euro News, one of Wandercraft's test pilots, Kevin Piette, noted, “the first time you stand up is pretty impressive because you can do it very easily, very quietly, comfortably. And then you have this upright posture that you had actually forgotten about.”

One of Piette’s favorite rediscovered activities is cooking. “To be able to cook and reach things up high, things that are part of a really banal day of life was rewarding. It’s also really nice to be able to be at the same level as people instead of always looking up at them from below,” he told Euro News.

Wandercraft first launched in 2012, starting out with only three engineers. The company now has 50 mathematicians, robotics engineers and biomechanical experts. And so far $45 million has been raised to further develop a lighter, cheaper, more versatile model.

One of those co-founders, Jean-Louis Constanza, whose son is a wheelchair user, credits their success to having “a project that really changes society.”

According to the Wheelchair Foundation, an estimated 10 million people require wheelchairs. And that’s not taking developing countries into consideration, where less than 10% of those who need them actually have access to one. According to the website, that means that every hour of every day, there is need for 145 more wheelchairs in the world. There is certainly a demand for mobility devices.

Lots of breakthroughs have been made to make everyday life a bit more accessible for those who are disabled, like wheelchair-equipped smart cars. But the Atalante X is something truly innovative and one-of-a-kind. Its next steps (pun intended) are being able to be used outside. Wandercraft engineer Jean-Louis Kana noted that the device will have to adhere to the same regulations as an autonomous car, and be required to develop algorithms to ensure stability and reliability. Particularly if there’s an accident.

However, if the success of Wandercraft continues, the lives of millions will become truly limitless. It’s one small step for robotics, and one giant leap for inclusion.

Dad camping with his kids shared the handwritten note left on his car from a fellow camper

More of this, please.

A dad got a sweet note from a fellow father after camping with his kids.

One of the hardest parts of being a parent is never being sure whether you're doing a good job or totally bombing it. If you're conscientious enough to even wonder if you're a good parent, you probably are, but parenting entails a million little choices and interactions, and there's always a lingering voice in your head saying, "What if you're really screwing this whole thing up?"

Reassurance and encouragement are always appreciated by parents, but not always received, which is why a note from one camping dad to another has people celebrating the kindness of anonymous strangers.

"You are killing it as a dad."

Someone on Yosemite Reddit thread shared a photo of a handwritten note with the caption, "To the man who left this thoughtful note on my windshield at Lower Pines Campground this weekend, I extend my heartfelt gratitude; your acknowledgment of my efforts to be a good father means a great deal to me."


Windshield Note.
byu/RCampR6 inYosemite

The note reads:

"Bro,

I camped in the spot behind you last night. Let me just say, you are killing it as a dad. First off, I watched your wife guide you in as you backed up your trailer and nailed it on the first try without any yelling. Then your kids unloaded from the truck and were mild-mannered and well behaved. You told stories around the campfire and I had the pleasure of listening to the sounds of giggles and laughter.

From one dad to another, you are killing it. Keep it up.

P.S. Whatever you cooked for dinner smelled delicious!"

How often do we share these thoughts with strangers, even if we have them? And who wouldn't love to get a surprise bit of praise with specific examples of things we did right?

Everyone needs to hear a compliment once in a while.

So many people found the note to be a breath of fresh air and a good reminder to compliment people when we feel the urge:

"That would make any daddy's eyes water."

"It’s always nice, as a guy, to get a compliment."

"I complimented a guy's glasses at work (I'm also a guy, and btw they were really cool glasses, I wasn't just being nice) and now he keeps trying to tell me where he got his glasses and how I should get some. But I'm just having to be polite because I already have glasses and I'm not in the market. I finally had to tell him I'm not going to buy them lmao I just like them on him.

Made me feel like that's the first compliment he's had in years because he can't stop talking about it. Also I mainly liked the glasses because I think he's cute but he really thinks it's just the glasses haha jokes on him that cute bastard."

via GIPHY

"I was in the store with my wife and one of our 'adopted nephews' yesterday (we’re close friends with his parents and we’ve known him and his brother since they were newborns and 2yo, respectively). A woman came up to me at checkout while my wife was running out to the car and said 'I’m not sure what your family relationship is here, but I just have to tell you how nice and refreshing it is to hear all the laughter and joy from the 3 of you. You both seem like such a good influence on him and it warms my heart.' It’s such a small thing but as a dude, I can’t remember the last time someone gave me a compliment in public and it made my freaking day."

"10/10 letter. The and not yelling part gave me a good chuckle lol."

"We need so much more of men getting such heartfelt and sincere compliments. Thanks for sharing. ❤️"

"I’ve never considered leaving a note, but when I see a harmonious family with good parenting, it’s healing for me. My childhood was awful."

"Such an awesome compliment! Even though I don't have children myself, I like to remind my friends too that they're doing great & it brings them happy tears."

via GIPHY

"This made me cry. I love that you are getting your 'flowers.' My dad sucked, I’m so glad you are one of the good ones."

"This made me cry too. It’s so hard to be a human. Let alone a parent. Getting a good job sticker every now and then really means a lot these days."

"I'm a big bearded guy and I would cry if I got this note. More people like this, please."

The best part of this story is that no one knows who the dad who wrote the note is, not even the dad who shared it. It wasn't written for clout or notoriety, it wasn't to get attention or make himself look good. No name or signature, just an anonymous act of kindness to uplift a stranger whether he needed it or not.

We all need to hear or read kind things said about us, and sometimes it means even more coming from an anonymous stranger who has nothing to gain by sharing. A good reminder to share it when you feel it—you never know how many people you may move and inspire.

Historian of infant feeding debunks myths about how babies ate in the pre-formula days

Not everyone breastfed before formula was invented.

Public Domain/Wikimedia Commons, Carla Cevasco, PhD/Twitter

Prior to baby formula, breastfeeding was the norm, but that doesn't mean it always worked.

As if the past handful of years weren't challenging enough, one of the most harrowing issues the U.S. dealt with recently was the baby formula crisis in 2022.

Due to a perfect storm of supply chain issues, product recalls, labor shortages, and inflation, manufacturers are struggling to keep up with formula demand and retailers are rationing supplies. As a result, families that rely on formula were scrambling to ensure that their babies get the food they need.

Naturally, people weighed in on the crisis, with some throwing out simplistic advice like, "Why don't you just do what people did before baby formula was invented and just breastfeed?"

That might seem logical, unless you understand how breastfeeding works and know a bit about infant mortality throughout human history.

Rutgers University historian Carla Cevasco, Ph.D. shared some of the history of infant feeding in a viral X (formerly Twitter) thread to set the record straight. (Note: Cevasco provided sources for her facts, which can be viewed at the end of her thread on Twitter.)

"You may be hearing the argument that before the rise of modern commercial infant formula, babies all ate breastmilk and everything was great," she wrote. "As a historian of infant feeding, let me tell you why that’s not true."

Cevasco explained that, throughout history, people have had to feed infants food other than breastmilk for a variety of reasons.

"Sometimes the birthing parent was unable to breastfeed," she wrote, "Because: death in childbirth, or physical/mental health concerns, or need to return to work outside the home right after childbirth, OR their partner or enslaver forced them not to breastfeed so that they could return to fertility ASAP after giving birth.

"Sometimes baby was unable to breastfeed. Because: poor latch, prematurity, cleft palate, other health or disability reasons, etc.

"Sometimes baby was being cared for by carers other than birthing parent, including adoptive parents."

Cevasco went on to explain what babies ate instead of a parent's breast milk in those situations.

"Sometimes someone else would breastfeed the child," she wrote. "This might have been a relative or neighbor doing it for free. Or it might have been a paid or unpaid servant or enslaved person doing it at the expense of their own nursing infant, who might starve to death as a result."

She also explained that some babies thrived on alternative diets, which are not recommended today due to concerns about safety and nutrition.

"Wabanaki women in the 18th century sometimes fed infants a mixture of boiled walnuts, cornmeal, and water; an English colonist, Elizabeth Hanson, reported that her baby thrived on this diet," she wrote. "In early modern Europe, babies often ate pap or panada, mixtures of animal milk or water, bread crumbs or flour. Sometimes these were boiled, sometimes they weren’t."

However, she explained, those milk substitutes weren't always safe or nutritionally complete.

"So before the advent of modern commercial formula (in the 1950s), a lot of babies died of illness or starvation because they couldn’t breastfeed and the alternative foods were not safe or adequate," she wrote. "Let me repeat that: in the absence of modern formula, A LOT OF BABIES DIED OF ILLNESS OR STARVATION DUE TO LACK OF SAFE OR ADEQUATE FOOD."

As Cevasco illustrates, the idea that the pre-formula days were a bastion of infant health due to widespread breastfeeding is simply incorrect. Cevasco explained that better supports such as paid parental leave, free lactation consultation and education, better access to places to pump and so on, would go a long way toward increasing breastfeeding rates. She also pointed out that the greed of the corporate formula industry created the formula shortage crisis.

"But! Let’s not demonize formula because of an imagined past in which everyone breastfed," she wrote. "In the ACTUAL past, babies fucking starved and died of disease. Babies who would have survived today, because they would have had access to safe, nutritionally complete formula. Access that is now, horrifyingly and unjustly, under threat for many babies and their caregivers."

Cevasco pointed out that there are multiple safe and nutritionally complete ways to feed a baby, and making sure babies don't go hungry should be our main goal.

So many misinformed comments could be avoided with a basic understanding of what infant feeding looked like in the past, as well as a basic understanding of how breastfeeding works both physically and logistically. Let's spend more time informing ourselves and sharing facts from experts rather than continuing to perpetuate unhelpful and harmful myths about both breastfeeding and formula feeding.

They've been in love since the fifth grade. What better place to propose than where it all began?

It's like a real life rom-com!

Facebook

"It was always you."

We don’t often meet the love of our life in fifth grade. But for Simon Jenkins and Peyton Wynn, romantic destiny struck early.

At the ripe old age of 11 years old, Simon and Peyton met at Johnson Elementary School in Pinson, Alabama, where they sat together in Patti Hathorn’s class. Their relationship continued to grow with each passing year, lasting even after graduation. Ten years later Simon and Peyton both turned 21, and they're still each other’s special someone.

Fitting, then, that 10 years later, Simon and Peyton would celebrate their enduring love by getting engaged where it all began.

WVTM 13 anchor Rick Karle shared that Simon's mother Traci, “an event planner with a flair for the artistic,” suggested the nostalgic setting for his 2022 proposal. Getting Simon’s approval, she quickly laid out handcrafted signs, flowers and candles, making everything look extra special for the sweet moment.

Who knew a classroom could be so romantic?

The next part of the surprise would be entirely up to Simon. He told WVTM that the ruse had been getting a call from Traci as the couple made their way to a dinner date in celebration of their 10-year anniversary. She had “forgotten something at her PTA meeting at Johnson Elementary School,” and pleaded for them to go retrieve it. Nice one, mom.

Simon and Peyton made their way to the elementary school and found themselves in the lavish display. “You should have seen Peyton’s face when she walked into that classroom,” Simon told WVTM.

Judging by the photos alone, the proposal seemed to be something out of a Hallmark movie.

Spoiler alert: She said yes

For Peyton, it was the surprise of a lifetime. “I finally got to say yes to the love of my life. It was like something out of a dream,” the bride-to-be told People.

To make the moment that much sweeter, their fifth grade teacher was also there. How’s that for a satisfying full circle moment?

Patti Hathorn (now Patti Armstrong Hagwood) made her own endearing Facebook post, which read:

“For any teacher that is asked or wonders ‘Why we do what we do’. My response is this: We get to watch more than just academic growth in our classrooms. We watch laughter. We watch friendships blossom and grow. We watch as these relationships continue to develop, and often we get to witness them last a lifetime. And, in some instances, we are privileged to be a part of this continuance…It was such an honor to be asked to be present as Simon Jenkins proposed to his 5th grade love. It is another moment that reminds me of my ‘why’ as I continue to love ‘my’ children each year.”

I'm not crying, you're crying!

Hagwood continues to teach and welcomed another class that Fall. Coincidentally, that’s when Peyton and Simon will officially tied the knot, according to People.

Congratulations to the happy couple who gave us all a wholesome love story to smile about today. I guess the adage is true: when you know, you know.

Study shows that grandmas may feel closer to their grandkids than their own children

There's an important reason for it.

via PixaBay

A grandmother and grandchild.

For the past 55 years, scientists have theorized that a major reason why humans live so much longer past their reproductive years than other species is because of grandmothers. The "grandmother effect," as it's known, postulates that in hunter-gatherer societies, grandmothers played a vital role in finding food and raising children. In fact, the grandmother's role was so important that it had a huge impact on whether or not children survived.

"By relieving a mother of some of her child-raising responsibilities, so the thinking goes, grandmothers make it easier for their daughters to have more children and also make it possible for those children to have longer lives by helping them during the difficult early years of life," Haider J. Warraich writes in Stat. Two studies further this hypothesis by showing the important roles that grandmothers have in the survival of their grandchildren. A study of birth and death records in Finland for individuals born between 1731 and 1890 found that having a maternal grandmother between the ages of 50 and 75 increased a child's survival rate.

Another study found that proximity to grandmother matters, too. The shorter the distance between grandmother and grandchild, the more involved the grandmother can be and the more benefits that accrue to her daughter and grandchildren.

The grandmother effect could be a major reason why a new study shows that grandmothers may feel a closer emotional bond to their grandchildren than their own offspring.

A study by James Rilling of Emory Universityin Atlanta, Georgia published in "The Royal Society" measured brain function in 50 grandmothers with at least one biological grandchild between 3 and 12 years old.

Grandmothers were shown photos of their grandchild, an unknown child, an unknown adult and the same-sex parent of the grandchild. The study found that when a grandmother saw a photo of their grandchild it activated parts of their brain associated with emotional empathy and movement.

When the grandmothers saw a photo of their adult child, it activated areas of the brain associated with cognitive empathy. So, to put it simply, when shown the pictures, the grandmothers were attempting to emotionally empathize with their grandchildren while trying to cognitively understand what their adult children were thinking.

"That suggests that grandmothers are geared toward feeling what their grandchildren are feeling when they interact with them," Rilling said in an Emory news article. "If their grandchild is smiling, they're feeling the child's joy. And if their grandchild is crying, they're feeling the child's pain and distress."

Given the importance of the grandmother effect, it's no surprise that our grandmothers seem to be hardwired to love us in the deepest way possible. Science shows that without this incredible bond, humans may not have made it this far. Conversely, it also shows that without having such an important role in their post-reproductive years, our grandparents may not have evolved to live so long.

In the end, the relationship appears to be symbiotic. Grandmothers promote the survival of a child who one day may grow up to be a grandparent and live longer because they have such an important role in the life of their grandchild.

Kind scuba divers try to convince a tiny octopus to trade its plastic cup for a shell

The video, which has been viewed more than 18 million times, almost feels like real-life Pixar short.

Pall Sigurdsson/YouTube

Sometimes taking care of our beautiful home planet looks like big, broad policies tackling issues like plastic pollution and habitat destruction. And sometimes it looks like taking the time to help one tiny creature in an environmental bind.

In a YouTube video that's been viewed a whopping 18 million times, we see an example of the latter in action as some kind and compassionate divers attempt to convince an octopus to abandon the plastic cup it's using for protection and trade it for a sturdy shell. Pall Sigurdsson has shared dozens of underwater videos on YouTube, but watching this particular video from his dive off the coast of Lembeh, Indonesia a few years ago almost feels like watching a Pixar short film.

"We spent a whole dive and most of our air saving this octopus from what was bound to be a cruel fate," Sigurdsson wrote in the description of the video.

"The coconut octopus, also known as veined octopus, is born with the instinct to protect itself by creating a mobile home out of coconut or clam shells. This particular individual however has been trapped by their instincts and have made a home out of a plastic cup they found underwater."

Sigurdsson explained that a predator like an eel or a flouder would probably end up swallowing the cup with the octopus in it, likely killing both of them.

"We tried for a long time to give it shells hoping that it would trade the shell," he wrote. "Coconut octopus are famous for being very picky about which shells they keep so we had to try with many different shells before it found one to be acceptable."

If you think an octopus in a cup making a decision about shells doesn't sound riveting, just watch:

Octo in a cupwww.youtube.com

The tentacles reaching out to test the weight of each shell, the divers searching for more options to offer it, the suspense of wondering whether the octopus really would abandon its pathetic plastic pollution protection...it's just too much.

Funny how one small interaction in one tiny portion of the vast ocean can say so much about us, for better and for worse. Human pollution is an enormous problem and saving one little octopus won't save the world, but it sure gives us hope and motivation to keep trying.
