Eco-friendly concrete could make your morning commute a lot smoother.

Imagine a world with no more spilled coffee because of bumpy roads.

Road salt — nearly 1 million tons of it just in the state of Pennsylvania — is used to keep cars safe on the road.

In the aftermath, however, it means thousands of cracks, potholes, and other damages in roads that need to be repaired each year because the chemicals in the salt "dice up" asphalt and concrete when the salt causes the water in snow to stick around, freeze, and do some damage.

Fortunately, there may be a new type of concrete coming to town.

It's made from coal furnace leftovers and uses less calcium hydroxide — the ingredient that reacts with road salt and causes that frustratingly pore-like reaction in concrete — which means you'd be riding a bit smoother on it.

The concrete is even more durable than what we use now because it doesn’t react with road salt and is made from recycled materials.

"Many departments of transportation have reduced the amount of calcium chloride they use to melt ice and snow, even though it is very efficient at doing so — because it has also been found to be very destructive," said Dr. Yaghoob Farnam, assistant professor at Drexel University in Philadelphia and lead researcher on the team behind the new mixture.

By recycling power industry byproducts such as fly ash, silica fume, and slag that would normally get tossed and become harmful to the environment to make the concrete, Farnam's team came up with a solution to the thousands of road-related repairs caused by salt damage that is also environmentally friendly.

Not all roads are made of concrete, but many sidewalks and parking lots are.

This new concrete could be a relief to anyone who's ever broken a carton of eggs after guiding a shopping cart over a cracked parking lot or ended up with a lap full of joe while drinking a cup of coffee on a morning commute.

(Since so many people drink java and drive, this could be a major game changer when it comes to safety as well — although, you may want to rethink that when so many accidents are caused by distracted coffee-sippers behind the wheel.)

This may not be in your city tomorrow, but you can help move things along.

Safe, healthy, durable infrastructure takes time to build the right way, Farnam cautions, but it’s important for government leaders and local municipalities to consider infrastructure decisions as long-term plans and spend the time to come up with intelligent, sustainable solutions. That may include the need for this type of research to be done for other road-building materials like asphalt.

Try attending local municipal meetings and talking to decision-makers about how they gather information about infrastructure choices. You may also want write in to state legislators to suggest sustainable solutions like this one.

If you want to start at the source, you might even try asking those legislators to support funding for research on projects like this with your own local department of transportation.

"This would help scientists understand what are real challenges in our society, and it will also help the leadership and contractors to learn about the new technologies that they can use on a daily basis," Farnam says.

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.

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.

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.
