UK project to reduce PFAS pollution is awarded Stockholm Junior Water Prize
Christopher Whitfield and Wenqi (Jonathan) Zhao from the United Kingdom receive the prestigious Stockholm Junior Water Prize 2024 for their work on PFAS pollution in the Thames Basin. HRH Crown Princess Victoria of Sweden presented the winners with their award during a ceremony at World Water Week in Stockholm.
Per- and polyfluoroalkyl substances (PFAS) pollution is a growing concern worldwide. Focusing on the Thames Basin in the United Kingdom, where there are with no equitable solutions to the problem, Whitfield and Zhao developed a geospatial neural network, predicting PFAS values to within 10 percent of experimentally validated values.
For this, they were announced the winners of the Stockholm Junior Water Prize, an international competition where students between the ages of 15 and 20 present solutions to major water challenges.
Speaking on winning the prize, Zhao said, “We are very proud to have won this prize. It has been an amazing stay here in Sweden with so many new friends”.
The Jury noted that Whitfield and Zhao “find a way to take data and turn it into actionable knowledge. [They have] identified PFAS hotspots using machine learning, field tested their results, developed a cost-effective filtration system, and reached out to local governments and environmental organizations to raise awareness.”
The winners were presented with their prize during an award ceremony at World Water Week by HRH Crown Princess Victoria of Sweden, the Prize’s Official Patron.
The Diploma of Excellence was awarded to Shanni Valeria Mora Fajardo and Rosa Mendoza Sosa from Mexico for their work on how to reuse inked water with homemade filtration to produce veggie gardens.
The People’s Choice Award went to Manoel José Nunes Neto from Brazil, completing the line-up of winners.
The Stockholm Junior Water Prize has been organized every year since 1997. It is hosted by the Stockholm Water Foundation, with Xylem as Founding Partner.
“Innovation is paving the way to a more water-secure world, and the next generation are accelerating progress. The Stockholm Junior Water Prize competitors are an inspiring example of the ingenuity and passion young innovators bring to the table. On behalf of Xylem, I’d like to congratulate all those who took part in this year’s competition,” said Austin Alexander, Vice President of Sustainability and Social Impact at Xylem.

Vycellix Prepares for First-in-Human Study of Novel Allogeneic Cell Therapy Powered by Its Universal Cell Engineering Platform3.12.2025 19:00:00 EET | Press release
Vycellix, Inc., a biotechnology company developing next-generation allogeneic cell therapies designed to overcome the risk of immune rejection, today announced the successful completion of pre-clinical development for its universal cell engineering platform (VY-UC) with rigorous studies across many donor cell types proving robust immune evasion with functional persistence. The Company is now preparing for first-in-human clinical validation by seeking regulatory approval in Sweden to initiate a Phase 1 study for its lead VY-UC product candidate, a novel, off-the-shelf natural killer (NK) cell therapy (VNK-101) for patients with relapsed or refractory multiple myeloma. VY-UC is a single-step CD45 engager strategy intended to address a central barrier to donor-derived cell therapies, the host immune system’s rapid elimination of allogeneic cells. In pre-clinical studies, VY-UC expression enabled engineered donor cells to evade host cellular immune attack while retaining function, supporti
