A student accidentally created a rechargeable battery that could last 400 years

"This thing has been cycling 10,000 cycles and it’s still going." ⚡️⚡️

There's an old saying that luck happens when preparation meets opportunity.

There's no better example of that than a 2016 discovery at the University of California, Irvine, by doctoral student Mya Le Thai. After playing around in the lab, she made a discovery that could lead to a rechargeable battery that could last up to 400 years. That means longer-lasting laptops and smartphones and fewer lithium ion batteries piling up in landfills.

A team of researchers at UCI had been experimenting with nanowires for potential use in batteries, but found that over time the thin, fragile wires would break down and crack after too many charging cycles. A charge cycle is when a battery goes from completely full to completely empty and back to full again.

But one day, on a whim, Thai coated a set of gold nanowires in manganese dioxide and a Plexiglas-like electrolyte gel.

"She started to cycle these gel capacitors, and that's when we got the surprise," said Reginald Penner, chair of the university's chemistry department. "She said, 'this thing has been cycling 10,000 cycles and it's still going.' She came back a few days later and said 'it's been cycling for 30,000 cycles.' That kept going on for a month."

This discovery is mind-blowing because the average laptop battery lasts 300 to 500 charge cycles. The nanobattery developed at UCI made it though 200,000 cycles in three months. That would extend the life of the average laptop battery by about 400 years. The rest of the device would have probably gone kaput decades before the battery, but the implications for a battery that that lasts hundreds of years are pretty startling.

"The big picture is that there may be a very simple way to stabilize nanowires of the type that we studied," Penner said. "If this turns out to be generally true, it would be a great advance for the community." Not bad for just fooling around in the laboratory.

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.

Woman’s shocking before-and-after pictures reveal the truth about panic attacks

Appearances aren’t always what they seem.

Amber Smith on Facebook.

Feeling good.

In 2016, Amber Smith from Warwickshire, England, revealed something about herself that many of her Facebook friends didn't know: she suffers from crippling panic attacks.

Smith shared her story by posting two completely different pictures of herself and the powerful imagery was subsequently shared over 7,500 times.

"Top Picture: What I showcase to the world via social media. Dressed up, make-up done, filters galore. The 'normal' side to me.”

Full post:

God knows why I'm doing this, but people need some home truths..

Top picture: What I showcase to the world via social media. Dressed up, make up done, filters galore. The 'normal' side to me.
Bottom picture: Taken tonight shortly after suffering from a panic attack because of my anxiety. Also the 'normal'' side to me that most people don't see.

I'm so sick of the fact that it's 2016 and there is still so much stigma around mental health. It disgusts me that so many people are so uneducated and judgmental over the topic. They say that 1 in 3 people will suffer with a mental illness at some point in their life. 1 in 3! Do you know how many people that equates to worldwide?! And yet I've been battling with anxiety and depression for years and years and there's still people that make comments like 'you'll get over it', 'you don't need tablets, just be happier', 'you're too young to suffer with that'

F*** YOU. F*** all of you small minded people that think that because I physically look 'fine' that I'm not battling a monster inside my head every single day.

Someone actually said this to me one day 'aren't you too young to be suffering with anxiety and depression? What do you actually have to be depressed about at your age?'' Wow, just wow.

I'm a strong person, I've been through my fair share of crap in life (the same as anyone else) and I will be okay. I have the best family and friends around me and I am thankful everyday that they have the patience to help and support me.
To anyone who is going through the same, please do not suffer in silence. There is so much support around - Don't be scared to ask for help.

This is why I can't stress enough that it costs nothing to be nice to others. Don't bully others, don't put others down and the hardest one of them all (as we have all done it at some point) don't judge another person. We're all human regardless of age, race, religion, wealth, job. So build one another up instead of breaking each other down.
Peace & love guys

Smith's before-and-after photos perfectly symbolize how panic attacks feel, because they often come on without any warning. People suffering from attacks can experience shortness of breath, heart palpitations, trembling, hot and cold flashes or myriad other debilitating symptoms.

According to the National Institutes of Mental Health, over four million Americans suffer from panic attacks, and although they are emotionally debilitating, they can be overcome through cognitive/behavioral therapy. According to Thomas A. Richards, Ph. D, "Today, panic attacks and agoraphobia can be treated successfully with a motivated client and a knowledgeable therapist."

Eye-opening video shows why 80 percent of Americans live east of this line

You'll never see the U.S. the same again.

via YouTube/RealLifeLore

There's a big change at the 98th meridian.

Have you ever wondered why the eastern half of the United States is densely populated while everything west of Omaha, save for a few metro areas, is no man’s land?

Most people would assume that it’s because people first settled in the east and moved west. Or, they may believe it’s because of the vast desert that takes up most of the southwest. Those are some decent reasons, but it’s a much more complicated issue than you'd imagine.

A 20-minute video by RealLifeLore explains how topography and rainfall have created what appears to be a straight line down the middle of the country on the 98th meridian that dictates population density. Eighty percent of Americans live on the east side of the line and just twenty percent to the west.

RealLifeLore is a YouTube channel that focuses on geography and topography created by Joseph Pisenti.

In the video, we see that several large cities border the American frontier—San Antonio, Austin, Fort Worth, Oklahoma City, Wichita, Omaha, Lincoln, Sioux Falls, and Fargo, as well as Winnipeg up in Canada. To the west of those cities? Not much until you reach western California and the Pacific Northwest.

Why? Watch:

The major reason why the population drastically changes is rainfall. It rains much more on the east side of the line versus the west. The reason for the drastic change in rainfall is that the Rocky Mountains create a colossal wall known as a rain shadow that prevents moisture from passing from the Pacific Ocean. This has created a large swath of dry land that’s not conducive to larger populations.

Though the eastern U.S. is more densely populated, it doesn't mean the west doesn't sometimes feel crowded, especially if you live in Los Angeles County. What side of the line are you on?

Education

A school replaced detention with meditation. The results are stunning.

🙏🙌

Teaching students how to self-regulate had big results.


Imagine you're working at a school and one of the kids is starting to act up. What do you do?

Traditionally, the answer would be to give the unruly kid detention or suspension.

But in my memory, detention tended to involve staring at walls, bored out of my mind, trying to either surreptitiously talk to the kids around me without getting caught or trying to read a book. If it was designed to make me think about my actions, it didn't really work. It just made everything feel stupid and unfair.

But Robert W. Coleman Elementary School has been doing something different when students act out: offering meditation.

Instead of punishing disruptive kids or sending them to the principal's office, the Baltimore school has something called the Mindful Moment Room instead.

The room looks nothing like your standard windowless detention room. Instead, it's filled with lamps, decorations, and plush purple pillows. Misbehaving kids are encouraged to sit in the room and go through practices like breathing or meditation, helping them calm down and re-center. They are also asked to talk through what happened.

Meditation and mindfulness are pretty interesting, scientifically.

Mindful meditation has been around in some form or another for thousands of years. Recently, though, science has started looking at its effects on our minds and bodies, and it's finding some interesting effects.

A 2010 study, for example, suggested that mindful meditation could give practicing soldiers a kind of mental armor against disruptive emotions, and it can improve memory too. Another suggested mindful meditation could improve a person's attention span and focus.

Individual studies should be taken with a grain of salt (results don't always carry in every single situation), but overall, science is starting to build up a really interesting picture of how awesome meditation can be. Mindfulness in particular has even become part of certain fairly successful psychotherapies.

Back at the school, the Mindful Moment Room isn't the only way Robert W. Coleman Elementary has been encouraging its kids.

The meditation room was created as a partnership with the Holistic Life Foundation, a local nonprofit that runs other programs as well. For more than 10 years the foundation has been offering the after-school program Holistic Me, where kids from pre-K through the fifth grade practice mindfulness exercises and yoga.

"It's amazing," said Kirk Philips, the Holistic Me coordinator at Robert W. Coleman. "You wouldn't think that little kids would meditate in silence. And they do."

There was a Christmas party, for example, where the kids knew they were going to get presents but were still expected to do meditation first. "As a little kid, that's got to be hard to sit down and meditate when you know you're about to get a bag of gifts, and they did it! It was beautiful, we were all smiling at each other watching them," said Philips.

The kids may even be bringing that mindfulness back home with them. In the August 2016 issue of Oprah Magazine, Holistic Life Foundation co-founder Andres Gonzalez said: "We've had parents tell us, 'I came home the other day stressed out, and my daughter said, "Hey, Mom, you need to sit down. I need to teach you how to breathe.'"

The program also helps mentor and tutor the kids, as well as teach them about the environment.

They help clean up local parks, build gardens, and visit nearby farms. Philips said they even teach kids to be co-teachers, letting them run the yoga sessions.

This isn't just happening at one school, either. Lots of schools are trying this kind of holistic thinking, and it's producing incredible results.

In the U.K., for example, the Mindfulness in Schools Project is teaching adults how to set up programs. Mindful Schools, another nonprofit, is helping to set up similar programs in the United States.

Oh, and by the way, the schools are seeing a tangible benefit from this program, too.

Philips said that at Robert W. Coleman Elementary, there were exactly zero suspensions during the 2014-15 school year and beyond. For over two decades, they've been transforming lives and schools for the better. Check out their progress on their Instagram.

Her mother doesn't get why she's depressed. So she explains the best way she knows how.

Sabrina Benaim eloquently describes what it's like to be depressed.

Sabrina Benaim's “Explaining My Depression to My Mother."

Sabrina Benaim's “Explaining My Depression to My Mother" is pretty powerful on its own.

But, in it, her mother exhibits some of the most common misconceptions about depression, and I'd like to point out three of them here.

Misconception #1: Depression is triggered by a single event or series of traumatic events.

Depression isn’t just over sleeping.

Most people think depression is triggered by a traumatic event: a loved one dying, a job loss, a national tragedy, some thing. The truth is that depression sometimes just appears out of nowhere. So when you think that a friend or loved one is just in an extended bad mood, reconsider. They could be suffering from depression.

Misconception #2: People with depression are only sad.

The obligation of anxiety.

Most people who have never experienced depression think depression is just an overwhelming sadness. In reality, depression is a complex set of feelings and physical changes in the body. People who suffer from depression are sad, yes, but they can also be anxious, worried, apathetic, and tense, among other things.

Misconception #3: You can snap out of it.

Making fun plans not wanting to have fun.

The thing with depression is that it's a medical condition that affects your brain chemistry. It has to do with environmental or biological factors first and foremost. Sabrina's mother seems to think that if her daughter would only go through the motions of being happy that then she would become happy. But that's not the case. Depression is a biological illness that leaks into your state of being.

Think of it this way: If you had a cold, could you just “snap out of it"?

No? Exactly.

Oftentimes, depression is hard to understand for everyone.
