At 17, Gabriella Rothberg has done what most of us only joke about: she made a tomato that tastes like a hamburger. The Miami teen, a student at Ransom Everglades High School, recently received a U.S. patent for a genetically engineered tomato that produces heme—the iron-rich molecule that gives meat its savory flavor. It's a breakthrough that blends artificial intelligence, plant biology, and a very personal motivation.
Rothberg first had the idea at 15, while making a sandwich for her father. Two years later, her invention is not just a novelty but a serious biotech venture. She co-founded Impossible Vines with Maddison Marshall, a doctoral candidate at the University of Miami. Together, they're exploring how this tomato could address nutritional gaps in communities where meat is scarce or expensive.
How the hamburger-flavored tomato works
The science is as clever as the concept. Using AI, Rothberg designed the genetic constructs and even drafted the patent application. The team uses Agrobacterium as a biological vector to insert genes into the plant's cells, enabling the tomato to synthesize heme internally. This is different from the industrial bioreactor approach used by companies like Impossible Foods—here, the fruit itself becomes the factory.
But the path wasn't smooth. For months, the plants failed to grow. After consulting university experts, they discovered the culture medium had the wrong vitamin concentration. Once corrected, growth took off within weeks. "AI made all of this possible," Rothberg said.
The result is a tomato that, when bitten into, delivers a distinctly meaty taste. It's a concept that could reshape how we think about plant-based foods, especially in regions where access to animal protein is limited.
A family legacy of innovation
Gabriella's background is steeped in science. Her father, Jonathan Rothberg, is a pioneer in DNA sequencing and received the National Medal of Technology and Innovation from President Obama in 2016. Her mother, Bonnie Gould Rothberg, researches cancer risks in firefighters at the University of Miami. Dinner conversations at home often touched on evolution and physics—so it's no surprise Gabriella took to biotech.
The patent, issued in June 2026, lists both Gabriella and her father as inventors, with ownership under Impossible Vines Inc. It's a family affair, but the vision is global.
Nutritional promise and challenges ahead
The potential benefits go beyond novelty. Researchers are studying whether this tomato can provide absorbable iron, which is crucial for pregnant women in vulnerable regions. The plant also produces lycopene, a compound linked to cellular health. If successful, it could lower the cost of protein access in communities where meat is a luxury.
But there are hurdles. The team must conduct large-scale trials in uncontrolled greenhouses and ensure the iron is bioavailable enough to meet public health standards. Regulatory approval will be key before the first harvest reaches markets.
For now, the story is a milestone for young female scientists everywhere. As one supporter tweeted, "👏👏"—and indeed, it's worth applauding. For Miami, a city known for its vibrant culture and now its biotech ambitions, this is a reminder that innovation can come from the most unexpected places.
As the city continues to attract attention—whether through Art Basel's extended stay or the Latin Billboard Awards—this teen's invention adds a new layer to Miami's identity. It's not just about culture and entertainment; it's about science that could feed the world.
