This High School Student Invented a Filter That Eliminates 96 Percent of Microplastics From Drinking Water

Virginia teenager Mia Heller’s filtration system harnesses the power of ferrofluid, a magnetic oil that binds to microplastics in flowing water

by Ramsha Waseem, March 20, 2026

Excerpt: "A few years ago, teenager Mia Heller came across an article in her local newspaper about ongoing water quality issues in her neighborhood in Warrington, Virginia. Tests had revealed that the water available for daily consumption was highly contaminated with PFAS and microplastic pollution. The article further reported that government agencies would not be providing any funds for filtering the water.

" 'It was up to people to provide their own filtration,' says Heller.

"Not long after the article came out, Heller’s parents invested in an advanced water filtration system at her home. The system, however, required constant upkeep. Seeing her mother replace the water filter #membranes time and again, Heller set out to find a better solution.

" 'It inspired me to design a filter without the use of membranes, to decrease the costs and maintenance needs associated with water filtration,' says the now 18-year-old student at Kettle Run High School. Through her school, she also attends a half-day program for math, science and technology at nearby Mountain Vista Governor’s School.' "

[...]

" 'It was essentially just a container,' she says. Within the container was her filtration system, what she called a 'spinning magnified vial.' Heller harnessed a reusable magnetic oil called ferrofluid to selectively bind to microplastic particles as water flows through her filtration system. While her model successfully filtered out the #microplastics from the water in two simple steps, the system still required constant maintenance, as it did not self-recycle the ferrofluid.

" 'But if I could create a system that was able to basically clean itself and #reuse material,' she explains, 'the maintenance needs could go down by a lot.' "

[...]

"About five iterations later, she found the perfect solution. Her current prototype, which is about the size of a standard bag of flour, consists of three modules. The first unit, about a liter in volume, holds the contaminated water inside it, while the second stores the magnetic oil-based ferrofluid. The core process takes place in the third module, which is much smaller. 'A magnetic field pulls the microplastics out of the water, and the ferrofluid is recovered and reused in a closed loop,' explains Heller. As a stand-alone filter (similar to a Brita pitcher), the system can filter about one liter of water at a time."

"Here, we demonstrate that damaged #lysosomal #membranes are repaired by #microautophagy (a process termed “microlysophagy”) and identify key regulators of the first and last steps. We reveal the AGC #kinase STK38 as a novel microlysophagy regulator...microlysophagy is regulated by STK38 and GABARAPs and could be essential for maintaining lysosomal integrity and preventing #aging."

According to a new study, reverse osmosis, a process that uses membranes to filter water, has been misunderstood for decades. The study reveals that the conventional theory of reverse osmosis is wrong and that the membranes act as selective solvents, not sieves. The study could lead to more efficient and affordable water purification technologies and help address the global water crisis.

Yet another new theory suggests that memories may be stored in the membranes of your neurons. This contradicts the conventional view that memories are encoded in neuron connections. The theory could explain how memories are formed and retrieved and how they can be altered or erased. Despite more than half-century of research, we have only some twelve dozen contradictory theories and nowhere near establishing where and how memories are stored.

New #article by Amer Alam and colleagues, The Hormel Institute

Our collaborative work on ABCA7 is now online in EMBOJ https://lnkd.in/gwEh5QHY Owning to their role in in membrane homeostasis and lipoprotein generation, ABCA are of tremendous biomedical relevance. Here we combined cryoEM, microsecond long CGMD and functional assays to provide atomic details on the functions of ABCA7. Our CGMD simulations shows lipid partitioning into the ABCA7 and local membrane perturbations that underlie ABCA7 function. #cryoem #drugdevelopment #membranes #lipids #research

Hi, I am a membrane #biologist working at Osnabrück University DE. The group I run studies tumor suppressor functions of #lipids & how #cells seal holes in their membranes.

To grasp the complex behavior of #membranes, we love to hang out with #chemists, #physicists & computer simulations experts.

We encourage students to practice #hybridthinking and strive to be inspiring mentors for young scientists and society at large.

Looking forward to sharing and learning from you all!
