Working at tiny scales, scientists transform gold into something even more incredible.

Did he just call my wedding ring "boring"?

You've heard of nanotech, right? It's basically working with things that are really, really tiny.*

When you zoom into something to a super small scale, really surprising things can happen.

Take gold. We like it because it lasts a lifetime (and longer)! It makes good watches, rings, and coins because it doesn't react with oxygen and become tarnished or corroded. It just sits there, a gleaming symbol of never-ending love and power.

But if you zoom in much, much more closely to a tiny particle of gold, it transforms to something very different!

One of your grandparents can wear a gold ring that doesn't change in a lifetime. But up close, gold becomes a much more exciting scene.

Scientists have been able to attach molecules of drugs to surfaces of gold at this scale and use gold as a delivery vehicle to take medicines to particular sites in the body. Vroom!

Rod-shaped nano gold particles can be loaded up with antibodies that bond only to cancer cells. The nano gold can by made to oscillate via infrared light until — boom! Bad day for cancer cell.

Zoom in even farther, and things get really weird.

Super tiny pieces of gold can be used to change carbon monoxide to carbon dioxide. That kind of magic suggests that maybe we can use gold to make better breathing apparatus for fire fighters, for example, or to purify water.

We're already surrounded by products using nanotech. Nano silver in clothing and packaging fights bacteria that makes things stinky. Nano titanium dioxide makes sunscreens, paints, and other coatings more reflective, helping shield your body and your house from the sun.

These wondrous tiny things can also easily pass through cell membranes, taking new materials where they've never gone before. So, like with all new technologies, we do want to be careful to research the risks as well as the benefits as we develop and deploy it.

That said, the future looks pretty sparkly for nano gold!

5 things that made us smile this week

The animal edition!

True

Been stressed this week? Who hasn’t. That’s why we’re bringing you the latest in good news—five animal-themed stories we guarantee will put a smile on your face.

This week, we’re celebrating:

The most entertaining animal photos you've ever seen

Jason Moore/Comedy Wildlife Photography Awards 2023 and © Tzahi Finkelstein /Comedy Wildlife Photography Awards 2023

Need a laugh? How about a dozen laughs? Look no further than the 2023 Comedy Wildlife Photography Awards, a competition started in 2015 that focuses on the lighter side of wildlife photography. More than 1,800 photographers from around the world submitted photos, and the finalists—from a kangaroo playing air guitar to an arguing set of greenfinches—will absolutely make your day.

Healthier, happier, rescued pets

Hundreds of thousands of pets are relinquished to shelters each year, and many vulnerable pet populations—such as disabled and elderly dogs—can be hard to place in loving homes. Fortunately, Subaru has sponsored the rescue, rehabilitation, and adoption of more than 134,000 of these pets through the Subaru Share the Love® Event. As the largest corporate donor to the ASPCA® (The American Society for the Prevention of Cruelty to Animals®), Subaru and its retailers are donating a minimum of $300 to charities like the ASPCA for every new Subaru purchase or lease during the 2024 Subaru Share the Love Event, happening now through January 2, 2025.

This animal-centric (and adorable) creative writing assignment

A post shared by Amy • 3rd Grade Teacher (@theuniqueclassroom)

Amy McKinney, a third-grade teacher in Pennsylvania, recently had a genius idea for teaching her class persuasive writing: Rather than have them formulate an argument for an imagined audience (boring!), McKinney partnered with a local animal shelter and had her class write persuasive descriptions of each animal to help them get adopted. Each student chose a pet to write about and sent their essays to the shelter to display and post to the shelter’s social media channels. Student engagement was “tremendous,” said McKinney, and there’s no doubt these persuasive paragraphs made a huge difference in these shelter pet’s lives. Adorable.

The dog who saved his owner with CPR (yes, really)

Dogs have made the news for saving humans before, but have you ever heard of a dog performing CPR? That’s exactly what Bear, a Siberian Husky-Golden Retriever mix, did in 2022 when he found his owner unconscious on the floor after suffering a major heart attack. Not only was Bear able to quickly call for help, he even jumped on his owner’s chest repeatedly while someone else called the paramedics. Thanks to Bear, the owner survived what should have been a fatal heart attack. Now that deserves some head scritches.

Bee populations have reached a record high

Honeybees are essential to the planet, as they pollinate over 130 types of fruits, vegetables, and nuts. For years, honeybee numbers have been in decline—but happily, that’s starting to change. The US has added almost a million bee colonies in the past five years, with more than 3.8 million honeybees in total.

Woman who was pressured to quit her job to raise stepdaughter's baby makes a bold decision

This sparked an important conversation about family responsibility.

When parents can't step up, should grandparents step in?

A story that recently went viral on Reddit’s AITA forum asks an important question: What is a parent’s role in taking care of their grandchildren? The story is even further complicated because the woman at the center of the controversy is a stepparent.

At the time of writing her post, the woman, 38, met her husband Sam, 47, ten years ago, when his daughter, Leah, 25, was 15. The couple married five years ago after Leah had moved out to go to college.

Leah’s mom passed away when she was 10.

When Leah became pregnant she wanted to keep the baby, but her boyfriend didn’t. After the disagreement, the boyfriend broke up with her. This forced Leah to move back home because she couldn’t afford to be a single parent and live alone on a teacher’s salary.

Leah’s story is familiar to many young mothers facing similar difficulties.

The father isn’t involved in the baby’s life as a caretaker or financially. Sadly, research shows that 33% of all children in the U.S. are born without their biological fathers living in the home.

Single motherhood comes with unique hardships.

The new mother is a teacher and can’t afford to live on her own with a child. In 2019, a study found that out the top 50 U.S. cities, Pittsburgh is the only one where a new teacher could afford rent.

Today, Portland, OR has joined the very short list of cities where an "average teacher can afford 91.3% of apartments within community distance of their school" according to a recent study.

The stressors of taking care of the baby made Leah realize she needed help.

“But once she had the baby around 4 months back, Leah seemed to realize having a baby is not the sunshine and rainbows she thought it was,” the woman wrote on Reddit. “She barely got any sleep during the last four months. All the while Sam was helping her with the baby while I did almost all chores myself.”

“Now her leave is ending. She did not want to leave the baby at daycare or with a nanny,” the woman continued. “Sam and I both work as well.”

Leah asked her stepmother if she would stay home with the baby. The stepmother said no because she never wanted to have a baby and she has a job. “I asked why Leah can't stay home with the baby herself,” the woman wrote. “She said how she was young and had to build a career. I said many people take breaks to raise kids, and she broke down crying about how she was so tired all the time being a mom and needed something else in her life too.”

The demands of new motherhood are usually all-encompassing.

After the woman told her stepdaughter no, her husband pressured her to stay home with the baby. But she refused to give up her job to raise her stepdaughter’s child. “Leah said yesterday how she wished her mom was alive since she would have had her back. She said I didn't love her, and my husband is also mad at me,” the woman wrote. The woman asked the Reddit community if she was in the wrong for “refusing to help my stepdaughter with the baby,” and the community responded with rapturous support.

"[The woman] should tell her husband to knock it off and stop trying to pressure her into raising his daughter’s baby. If he wants a family member to look after her baby while she works, then he can do it," user Heavy_Sand5228 wrote.

"This is Leah's baby that she alone chose to have. That doesn't obligate you to change YOUR life to suit her desires. The whole business of saying you don't love her because you won't quit your job to watch her baby is manipulative and messed up, and I'm shocked your husband is siding with her," user SupremeCourtJust-a** added.

Leah and many women like her are in this situation because, in many places, teachers are underpaid, rent is high, and not all dads pay child support, even those required by law.

Another commenter noted that the baby is much more the father’s responsibility than the stepmother's. "To add, Leah should consider seeking child support from her ex. Her kid should be getting that money," Obiterdicta wrote.

While there are resources to help stepparents connect with their stepchildren and step-grandchildren, it's important to remember that the responsibility to raise a child ultimately rests with the parent(s).

Hospice nurse reassures people worried by recent footage of Jimmy Carter at 100

Carter has been in hospice care for nearly 2 years.

Julie McFadden and former President Jimmy Carter.

Former President Jimmy Carter is known for being one of the most beloved former presidents in American history for his resolve to use his talents to help others, whether it was eradicating the Guinea worm or his work with Habitat for Humanity into his late 90s. Carter says that his faith is the big reason for his resilience. “I have one life and one chance to make it count for something,” he said. “My faith demands that I do whatever I can, wherever I am, whenever I can, for as long as I can with whatever I have to try to make a difference.”

The man who held the presidency from 1977 to 1981 went into hospice in February 2023 but has lived much longer than most expected. Carter has made 2 public appearances in that time, the first in November 2023 for the funeral of his wife of 77 years, Rosalynn and on October 1, 2024 for his 100th birthday. When Carter was wheeled into his wife’s funeral, some family members expressed shock and worry about Cartter’s appearance.

— (@)

Since beginning hospice care, Carter has appeared frail and gaunt without expression and mouth agape. It shouldn’t be shocking for a person who has reached the age of 100 to appear so fragile, but it’s right to be concerned that he may be uncomfortable in such a state. However, Julie McFadden, also known as Hospice Nurse Julie, settled a lot of people’s fears in a TikTok video where she explained Carter’s appearance and why he’s most likely comfortable during his transition.

McFadden has assisted over a hundred people in their final days and is the author of the bestseller, "Nothing to Fear."

What is Jimmy Carter's condition?

“I have been tagged in this Jimmy Carter turns 100 years old today video,” she begins her viral TikTok with over 600,00 views. “So many times people asking me, why does he look like this? Is he okay? Does this mean anything? As a hospice nurse, this video was not alarming to me. Jimmy Carter, to me, looks just like someone who was 100 years old on hospice and getting towards the end of their life.”

She then speculated on what his life is like at age 100. “Jimmy Carter is likely sleeping 20 to 22 hours a day. He is likely not really eating and drinking, which is all normal and to be expected at the end of life. So that's why he looks so thin. He looks cachectic. His body is slowly shutting down and the more we just let his body be the guide, the better he will be.”

A lot of people are concerned about the way that Carter’s mouth seems to be permanently open. McFadden says that is due to muscle wasting. “His mouth is hanging open because it takes muscles to keep your mouth shut. And at the end of life, those muscles relax. So he is likely so relaxed that when he's sleeping, which is most of the time, even when he's in a wheelchair, he's asleep, and his muscles relax, so his mouth hangs open.”

McFadden also addressed many people's concerns: Should Carter have been brought outside to celebrate his birthday with his family in such an advanced state? Should he have been in front of the cameras?

“In my opinion, it's up to the family. The family knows that person best,” McFadden said. “From what we know of Jimmy Carter, he was a family man who loved being around his family. So why not be around him and celebrate his one hundred? One-hundredth birthday and bring family around, bring him outside. They know his personality. They must think he would love this. So let's do it. We don't have to keep dying people hidden away.”

McFadden is such an incredible gift because we tend to lock away the dying and talking about death and hospice is a very uncomfortable topic for most. This lack of information leads us to believe that someone in Carter’s position suffers. But, according to McFadden, he’s probably comfortable and relaxed. McFadden knows that when people better understand Carter’s condition, they will probably feel better about their final days as well.

I love Gordon's comics so much because they're just about the reality of parenting — and they capture it perfectly.

"I just hope this is a reminder to everyone that the simplest act of kindness from you can completely brighten a stranger’s day."

Passengers were annoyed, but commenters had some empathetic theories.

Commenters on the video — unlike some passengers on the flight — had a lot of empathy for the mysterious standing woman.
