Once a child who waited days for running water in Jordan, Nobel Prize-winning chemist Omar Yaghi is now helping pioneer a technology that could allow communities to collect fresh water directly from the atmosphere—even in some of the driest places on Earth.
Imagine living in a place where turning on the kitchen faucet does not guarantee that water will come out.
Imagine waking before sunrise, rushing to fill every available container, and knowing that whatever water your family collects may have to last another two weeks.
Now imagine that, decades later, you help develop a technology capable of pulling water from the air itself, potentially providing a new source of drinking water in places where conventional supplies are unreliable.
For Omar M. Yaghi, this extraordinary journey connects his childhood experiences in Jordan with one of the most exciting developments in modern materials science.
In October 2025, Yaghi, a professor at the University of California, Berkeley, received the Nobel Prize in Chemistry alongside Susumu Kitagawa and Richard Robson. The three scientists were recognized for their pioneering contributions to metal-organic frameworks, or MOFs, a class of materials containing remarkably intricate networks of microscopic spaces.
These materials can be engineered to capture particular molecules, including water vapor from the atmosphere.
The implications are enormous.
Scientists have already demonstrated devices that collect water from dry air using specially designed porous materials. Yaghi's research has helped move the concept from laboratory experiments toward practical systems, while commercial development efforts are exploring larger devices capable of producing hundreds of liters of water daily.
The ambition is to reach production levels of approximately 1,000 liters per day with larger systems, although such targets must be distinguished from independently verified, routine performance under real-world conditions.
What makes this scientific achievement particularly compelling is that Yaghi understands the importance of water not only as a chemist, but also as someone who grew up experiencing its scarcity.
His story illustrates how fundamental scientific discoveries, personal experiences, and decades of persistence can converge around one of humanity's most urgent challenges.
8A Childhood Shaped by the Value of Water
Omar Yaghi was born in 1965 in Amman, Jordan, into a Palestinian refugee family.
His early life was far removed from the research laboratories, international conferences, and prestigious academic institutions that would eventually define his professional career.
Growing up in a large family, he became familiar with circumstances in which access to essential resources could not be taken for granted.
Water was one of those resources.
In his childhood neighborhood, the municipal water supply was intermittent. Rather than flowing continuously through household pipes, water might become available only once every week or two.
When it arrived, families needed to act quickly.
Containers and storage reservoirs had to be filled while the supply lasted. Missing that brief opportunity could mean facing many more days without running water.
Yaghi has recalled waking early to make sure his family's water storage was replenished.
It was a responsibility that taught him an important lesson long before he became a scientist: water was not something that could always be obtained simply by turning a tap.
For people living in regions with reliable water infrastructure, the significance of that experience can be difficult to appreciate.
A household with continuous running water can use it for drinking, preparing meals, washing clothes, bathing, cleaning, and sanitation without constantly calculating how much remains.
For families facing intermittent supplies, nearly every domestic activity requires planning.
Water used for one purpose may no longer be available for another. Storage capacity becomes important. So does cleanliness, because water kept for long periods must be protected from contamination.
The uncertainty itself creates a burden.
Even when enough water can be stored to meet basic needs, families remain dependent on the next delivery or the next period of municipal supply.
For a child, these circumstances can shape an understanding of security, responsibility, and the value of resources.
Yaghi's experiences would later become deeply connected to his interest in developing technologies capable of expanding access to clean water.
Yet his journey into chemistry did not begin with a fully formed plan to solve the world's water problems.
It began with curiosity.
The School Library Discovery That Changed His Life
One of the most memorable stories from Yaghi's early life concerns a visit to a school library when he was around ten years old.
There, he encountered illustrations of molecular structures.
The drawings represented arrangements of atoms and chemical bonds—concepts that were far beyond the scientific knowledge he possessed at the time.
But something about their patterns fascinated him.
He did not yet understand the chemistry behind them. He could not explain why the atoms were arranged in particular ways or how those structures determined the behavior of substances.
Nevertheless, the images captured his imagination.
In a lecture published by UC Berkeley in March 2026, Yaghi described the fascination he experienced when he first encountered these molecular diagrams.
That childhood moment offered a glimpse into a world in which matter could be understood at scales invisible to the human eye.
Ordinary materials, he would eventually learn, were built from atoms connected through chemical bonds. Their properties depended not only on which atoms were present but also on how those atoms were organized.
This idea would become central to his life's work.
Rather than simply studying the properties of naturally occurring materials, Yaghi would help develop methods for designing entirely new structures with carefully controlled internal arrangements.
Such structures could be built to perform specific tasks.
Some might capture gases.
Others might store molecules, accelerate chemical reactions, or selectively absorb substances from their surroundings.
Eventually, certain materials would be engineered to collect water vapor from air.
The path from a school library in Amman to advanced molecular engineering was neither immediate nor straightforward.
It required education, opportunity, persistence, and the willingness to pursue scientific questions whose practical significance was not always obvious.
But the connection between childhood curiosity and later discovery is striking.
