Imagine what the world would look like if industrialized countries had skipped the age of fossil fuels and gone directly to solar power.

Our infrastructure, way of life, and environment would be radically different.

That’s the future 23-year-old entrepreneur George Mtemahanji envisions for his home country of Tanzania.

Of the more than 51 million people living in Tanzania, 70% don't have electricityat all, either because they’re not connected to the energy grid, or, if they are, they still don't have electricity due to poor connections and frequent outages.

Mtemahanji knows firsthand what it's like to live without electricity.

He grew up studying by kerosene light and going to bed at 8 p.m. (the sun goes down in Tanzania at 6 pm).

"I understand very well the discomfort that people who have no electricity have," he told Upworthy via email. "I was born at night in a clinic without electricity, and so I was born with the light of the moon. My mom always told me that she had to wait [until] the next day to see me, she knew I was born healthy because I weighed nearly 4kg, but she could only see me the next morning. ...I was born and I lived without electricity and I know what it means, for this I decided to use all my knowledge to light up the lives of all those who do not have electricity."

In 2003, Mtemahanji moved to Italy with his mother and became a technician in renewable energy before going to work in Switzerland. By 2014, he’d saved up enough to return to Tanzania, where he started a business with a friend, Manuel Rolando.

The business they started is called SunSweet Solar Limited, and it has the potential to solve three major problems at the same time.

Solar power seemed to Mtemahanji and Rolando like the perfect way to resolve a few different problems simultaneously — (1) bringing electricity to people who needed it, (2) in areas that were mostly poor, and (3) without contributing to climate change.

SunSweet Solar designs, plans, and constructs solar photovoltaic systems, water pumping systems, street light systems, and off-grid lighting.

SunSweet Solar's first contract involved installing a solar power plant at a secondary school that could run 236 lights, dozens of computers, and fans.

The project was challenging, but it was also a success, and Mtemahanji was curious to see how having electricity affected the students.

He wasn't disappointed; he says that since SunSweet Solar's installation last year, national exam performance at Benignis Girls Secondary School increased from 81% to 94%.

Mtemahanji attributes at least some of that success to the introduction of electricity.

"This result shows that studying in a serene environment where electricity is always present, can help a lot to improve the quality of education."

In addition to big projects like the Benignis school, the company sells solar kits and installs larger scale solar systems.

The plan originally was to sell solar kits capable of powering a few lightbulbs and charging a phone to individual households, but SweetSun Solar has since changed its model: nNow they install single solar systems that can satisfy the energy demands of a whole village.

SunSweet Solar customers pay for the solar setup in installments through their phones, and it costs them about $0.13 a day. The government of the village earns 5% of the revenue to assist in the development of the village.

In October 2015, SunSweet Solar was selected as one of the 12 best companies led by young Africans‎ by the Anzisha Prize, an award celebrating young African entrepreneurs.

Since the award, sales have skyrocketed, and SunSweet Solar now faces a new challenge: how to keep up with demand. The company gets requests from about four villages every month, each village with an average of 30 customers/houses. Mtemahanji and Rolando are currently looking for investors so that they can scale up their business.

Mtemahanji says it can be discouraging because it seems like many investors want to work with Western and Asian companies operating in Africa rather than directly with Africans.

"We must be content with the funds that we can have through the seed and prizes. But many of these funds help to support the company, not to scale up. I am confident, however, that this situation will change soon as possible, and we are ready for that moment."

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.
