I desperately need to clean out my freezer. There are things there I'd swear I haven't seen in years. What is this? Chicken? Why do I have frozen tamales? When did I eat sweet potatoes?

Well, it turns out Mother Nature has this conundrum too.


The permafrost is kind of like nature’s own deep freeze.

The permafrost is a band of permanently frozen land that rings the Arctic Circle, and it makes up about a quarter of all the land in the Northern Hemisphere. Some sections can be nearly a mile thick! And though the top layer may thaw and re-freeze as the seasons change, the lower levels stay ice cold and rock solid.

Which makes it an amazing place to find old, preserved things. Some of which are, frankly, astounding.

Without further ado, here are six of the weirdest things to come out of the permafrost.

1. Ancient plants

In 2012, a team of Russian scientists revived 30,000-year-old plants they found frozen in the tundra. The plants appeared to be an ancient form of narrow-leafed campion and were found in the cache of an ice-age ground squirrel.

The scientists brought the plants back to the lab and, through a little coaxing, were able to actually grow new specimens. They even flowered and produced new seeds!

2. Giant viruses

Inspired by the Russian team’s success with the plant, other scientists wanted to see what else they could find preserved in the permafrost. By fishing through samples of permafrost, the scientists found a 30,000-year-old monster of a virus dubbed Pithovirus sibericum.

The virus was staggering large, nearly the size of a bacteria. If you don't know viruses, that's like finding a cat the size of an rhino. What’s more, it seems almost alien — two-thirds of its proteins are unlike those of any other virus. No need to worry, however, as it appears to only hunt amoebas. We’re not on the menu.

3. Woolly mammoths

In 2007, a reindeer breeder named Yuri Khudi found something odd in the frozen tundra of Russia's Yamal Peninsula. He trekked over 150 miles to notify a local museum director. When authorities arrived, they found a nearly 42,000-year-old baby mammoth.

The baby (which had been moved to outside a local store) was named Lyuba after Khudi's wife. Lyuba is one of the best-preserved mammoths in the world; scientists could even tell what she ate before she died.

Lyuba is only one of many mammoths unearthed in the permafrost. Other ice-age animals have been found too, like horses and woolly rhinos.

4. Really weird shapes

Not everything that comes out of the tundra is alive. Sometimes the Earth itself gets freaky.

These weird shapes include small, volcano-shaped hills called pingos (which some people have claimed to have seen explode like massive, icy landmines), ice wedges, and geometric shapes made of rocks. These weird shapes happen when water in the ground keeps freezing and thawing.

In the last few years people have even reported massive craters. The craters were probably made when underground gases built up and exploded outward.

5. Human bodies

People sometimes bury bodies in the frozen ground. And sometimes those bodies don’t stay buried.

In the 1980s, for instance, a river exposed a mass grave near Pokhodsk, Siberia. There are some fears that bodies like these could be reservoirs for past diseases. In 1998, six frozen bodies in Svalbard were found to have traces of the Spanish flu, which killed 50 million to 100 million people in the early 20th century.

6. Puppies

Scientists have found dogs in the permafrost, including a family of puppies. The animals were likely buried in a landslide and were in amazing condition, considering they were over 10,000 years old.

"The condition of our new find is perfect," Sergei Fedorov, head of exhibitions at the Mammoth Museum of Yakutsk, told The Siberian Times. "It is preserved from nose to tail, including the hair."

The dog could be one of the earliest domesticated breeds and may even be the same kind of dog that crossed the Arctic land bridge into North America along with people.

But there's something else coming out of the permafrost. And it's not so much weird as it is a bit worrisome.

Besides puppies and mammoths, the permafrost has also trapped a lot of old organic matter, like peat moss and decayed plants. If the permafrost thaws and that stuff starts to rot, it could release a lot of methane and carbon dioxide into the atmosphere.

And it looks like a huge thaw is on the way. Climate change could thaw a quarter of Alaska's near-surface permafrost by 2100. Other parts of the world are expected to lose just as much, and 60% of the world's permafrost may be gone by the end of the next century.

If that 60% happens, it will release an estimated 190 billion tons of carbon dioxide — as much as half of all human activity has released since the industrial age. And the trapped methane could have an even bigger impact — the equivalent of another 7.5 billion to 400 billion tons of carbon dioxide to the atmosphere.

That would have a massive impact on the atmosphere and could fundamentally change our global climate.

Luckily, there's something we can do. Stop leaving the freezer door open already.

Slowing our own carbon emissions is one of the best ways we have of reducing climate change and keeping the permafrost perma-frosty.

As cool as all these discoveries are, I don't mind it if some things stay frozen for the sake of our world.

Artist uses AI to create ultra realistic portraits of celebrities who left us too soon

What would certain icons look like if nothing had happened to them?

Mercury would be 76 today.

Some icons have truly left this world too early. It’s a tragedy when anyone doesn’t make it to see old age, but when it happens to a well-known public figure, it’s like a bit of their art and legacy dies with them. What might Freddie Mercury have created if he were granted the gift of long life? Bruce Lee? Princess Diana?

Their futures might be mere musings of our imagination, but thanks to a lot of creativity (and a little tech) we can now get a glimpse into what these celebrities might have looked like when they were older.

Alper Yesiltas, an Istanbul-based lawyer and photographer, created a photography series titled “As If Nothing Happened,” which features eerily realistic portraits of long gone celebrities in their golden years. To make the images as real looking as possible, Yesiltas incorporated various photo editing programs such as Adobe Lightroom and VSCO, as well as the AI photo-enhancing software Remini.

“The hardest part of the creative process for me is making the image feel ‘real’ to me,” Yesiltas wrote about his passion project. “The moment I like the most is when I think the image in front of me looks as if it was taken by a photographer.”

Yesiltas’ meticulousness paid off, because the results are uncanny.

Along with each photo, Yesiltas writes a bittersweet message “wishing” how things might have gone differently … as if nothing happened.

It begins with more inclusive conversations at a patient level

True

Adewole Adamson, MD, of the University of Texas, Austin, aims to create more equity in health care by gathering data from more diverse populations by using artificial intelligence (AI), a type of machine learning. Dr. Adamson’s work is funded by the American Cancer Society (ACS), an organization committed to advancing health equity through research priorities, programs and services for groups who have been marginalized.

Melanoma became a particular focus for Dr. Adamson after meeting Avery Smith, who lost his wife—a Black woman—to the deadly disease.

This personal encounter, coupled with multiple conversations with Black dermatology patients, drove Dr. Adamson to a concerning discovery: as advanced as AI is at detecting possible skin cancers, it is heavily biased.

To understand this bias, it helps to first know how AI works in the early detection of skin cancer, which Dr. Adamson explains in his paper for the New England Journal of Medicine (paywall). The process uses computers that rely on sets of accumulated data to learn what healthy or unhealthy skin looks like and then create an algorithm to predict diagnoses based on those data sets.

This process, known as supervised learning, could lead to huge benefits in preventive care.

After all, early detection is key to better outcomes. The problem is that the data sets don’t include enough information about darker skin tones. As Adamson put it, “everything is viewed through a ‘white lens.’”

“If you don’t teach the algorithm with a diverse set of images, then that algorithm won’t work out in the public that is diverse,” writes Adamson in a study he co-wrote with Smith (according to a story in The Atlantic). “So there’s risk, then, for people with skin of color to fall through the cracks.”

Tragically, Smith’s wife was diagnosed with melanoma too late and paid the ultimate price for it. And she was not an anomaly—though the disease is more common for White patients, Black cancer patients are far more likely to be diagnosed at later stages, causing a notable disparity in survival rates between non-Hispanics whites (90%) and non-Hispanic blacks (66%).

As a computer scientist, Smith suspected this racial bias and reached out to Adamson, hoping a Black dermatologist would have more diverse data sets. Though Adamson didn’t have what Smith was initially looking for, this realization ignited a personal mission to investigate and reduce disparities.

Now, Adamson uses the knowledge gained through his years of research to help advance the fight for health equity. To him, that means not only gaining a wider array of data sets, but also having more conversations with patients to understand how socioeconomic status impacts the level and efficiency of care.

“At the end of the day, what matters most is how we help patients at the patient level,” Adamson told Upworthy. “And how can you do that without knowing exactly what barriers they face?”

The mesmerizing lost art of darning knit fabric.

For most of human history, people had to make their own clothing by hand, and sewing skills were subsequently passed down from generation to generation. Because clothing was so time-consuming and labor-intensive to make, people also had to know how to repair clothing items that got torn or damaged in some way.

The invention of sewing and knitting machines changed the way we acquire clothing, and the skills people used to possess have largely gone by the wayside. If we get a hole in a sock nowadays, we toss it and replace it. Most of us have no idea how to darn a sock or fix a hole in any knit fabric. It's far easier for us to replace than to repair.

But there are still some among us who do have the skills to repair clothing in a way that makes it look like the rip, tear or hole never happened, and to watch them do it is mesmerizing.

Nurse turns inappropriate things men say in the delivery room into ‘inspirational’ art

"Can you move to the birthing ball so I can sleep in the bed?"

Holly the delivery nurse.

After working six years as a labor and delivery nurse Holly, 30, has heard a lot of inappropriate remarks made by men while their partners are in labor. “Sometimes the moms think it’s funny—and if they think it’s funny, then I’ll laugh with them,” Holly told TODAY Parents. “But if they get upset, I’ll try to be the buffer. I’ll change the subject.”

Some of the comments are so wrong that she did something creative with them by turning them into “inspirational” quotes and setting them to “A Thousand Miles” by Vanessa Carlton on TikTok.

“Some partners are hard to live up to!” she jokingly captioned the video.
