At age 17, American student researcher Dasia Taylor developed a low-cost surgical suture designed to change colour when infection develops in a wound, an invention that drew national attention for combining medical innovation with healthcare accessibility.

Taylor began the project in 2019 while studying at Iowa City West High School in Iowa. The idea emerged after a classroom discussion about science fairs and medical technologies, leading her to investigate advanced “smart” sutures already under development in the healthcare industry.

Existing smart sutures can detect infection-related changes by measuring electrical resistance and transmitting alerts through connected digital systems. However, Taylor concluded that such technologies were often expensive and difficult to deploy in low-resource healthcare settings lacking reliable internet access, smartphones or advanced medical infrastructure.

Instead, she focused on creating a simpler and less costly alternative that could visually indicate infection without requiring electronic equipment.Taylor’s breakthrough came after researching pH changes associated with infected wounds. She found that infected tissue typically becomes more alkaline and discovered that beet juice naturally changes colour at roughly the same pH range.

Using beet-derived dye applied to cotton-polyester surgical thread, Taylor developed sutures that shifted from bright red to dark purple under infection-like laboratory conditions.According to her tests, the colour transition occurred within approximately five minutes after exposure to pH levels associated with wound infection.

In the design, the beet extract functioned as the chemical sensor reacting to pH changes, while the cotton-polyester thread acted as the physical carrier for the dye compound.Taylor said the project evolved gradually through experimentation rather than beginning as a fully developed invention.

The work attracted attention because it addressed both scientific and public health concerns simultaneously. Taylor repeatedly framed the project around accessibility and affordability, particularly for communities where infections may go undetected because of limited healthcare resources.Her focus on equity later shaped the name of her venture, Variegate, which she said referenced both colour variation and social diversity.

Born in Chicago in 2004 and later raised in Iowa, Taylor has spoken publicly about growing up in a single-parent household and said those experiences influenced her interest in healthcare accessibility and social inequality.Alongside her scientific research, she became involved in educational and racial equity advocacy during her school years, participating in school board discussions and supporting conversations around anti-racist educational initiatives.

Taylor’s research project gained recognition through state and regional science competitions before reaching national prominence in 2021, when she was named one of 40 finalists in the Regeneron Science Talent Search, one of the most prominent science competitions for high school students in the United States.She also received the Seaborg Award as part of the competition.

Her work has since been featured by national media outlets and science education organisations, including appearances on PBS NewsHour and The Ellen DeGeneres Show.Taylor is currently studying at the University of Iowa while continuing efforts to patent the infection-detecting sutures and expand her healthcare-focused research initiatives.Medical researchers have increasingly explored “smart” wound-care materials capable of identifying infection earlier than traditional visual diagnosis.

Infections often alter wound chemistry before severe physical symptoms become visible, making early detection an important focus in surgical recovery and public health research.

Taylor’s work drew attention partly because it proposed a simpler, visually observable approach using widely available materials rather than relying on expensive digital monitoring systems.

The project has been widely cited by educators and STEM advocacy groups as an example of student-led innovation aimed at solving practical healthcare problems with low-cost solutions.

Saudi women are not just part of this change—they are actively shaping the Kingdom’s environmental future, turning sand into soil.

In the heart of the Kingdom’s vast deserts, an extraordinary transformation is taking place. Once barren stretches of sand are now being turned into fertile soil, and leading this revolutionary effort are Saudi women.

Saudi Arabia is undergoing a defining moment in its sustainability journey. Under Vision 2030’s Green Saudi Initiative, the nation is making bold strides toward reforestation, food security, and climate-resilient agriculture. However, what often goes unrecognized is that Saudi women are at the forefront of these efforts, driving groundbreaking scientific advancements to combat desertification and ensure a greener future.

With women now constituting 40 percent of graduates in science, technology, engineering, and mathematics (STEM), Saudi Arabia has surpassed many Western nations in gender diversity in these critical fields. But their impact extends far beyond the classroom—they are actively leading research, pioneering innovative environmental solutions, and implementing sustainable agricultural practices.

Orn Supaphol, Chief Technical Officer at Saudi Desert Control, highlights the critical role women play in environmental restoration. “In my work, I witness firsthand how Saudi women are leading projects that transform deserts into fertile land, improve water conservation, and develop long-term sustainability solutions,” she said.

One of Saudi Arabia’s most pressing environmental challenges is desertification—the loss of arable land due to climate conditions and soil degradation. Tackling this issue demands scientific breakthroughs, innovation, and long-term commitment. Across the Kingdom, Saudi women are rising to this challenge.

At Saudi Desert Control, researchers employ cutting-edge Liquid Natural Clay technology to enhance the water retention capacity of desert sand, making sustainable food production possible in one of the world’s most arid climates. Women scientists and engineers are spearheading the deployment of this technology, ensuring its success on the ground.

Beyond this, female researchers and agricultural engineers are leading efforts to reduce water consumption, implement regenerative farming techniques, and introduce climate-resilient crops. Their work is essential in ensuring food security and promoting sustainable farming practices.

Science and sustainability thrive on diverse perspectives, and the contributions of women in these fields lead to more effective decision-making, innovative solutions, and long-term resilience. Many of the most forward-thinking environmental advancements in Saudi Arabia today can be traced back to the efforts of female scientists and engineers.

“Saudi Arabia’s transformation is often spoken of as something coming in the future,” said Supaphol. “But working alongside incredible female colleagues, I can confidently say the future is already here.”

Saudi women are not just part of this change—they are actively shaping the Kingdom’s environmental future, turning sand into soil, conserving resources, and making sustainability a reality.

As the nation accelerates its sustainability drive, young Saudi women pursuing careers in science and environmental conservation will play a decisive role. Their contributions will define the next chapter in Saudi Arabia’s history, proving that the future of sustainability is not just coming—it is happening now.
