An architectural engineer by training, Al-Rashdan began experimenting with plant-based textiles in 2015. She learned to transform food waste—like beetroot skins, olive pulp, and onion peels—into biodegradable materials. Some are fed into a 3D printer to make handbags, coins, and jewelry; others are spun into fabrics for high-fashion dresses.

Paris said au revoirs to cars and see how air pollution halved.
A new peer-reviewed study in Science connects long-term exposure to fine particulate matter (PM2.5) with higher risk of Lewy body dementia (LBD) in a dataset of 56.5 million US Medicare records, and backs it up with animal experiments that show PM2.5 triggers toxic α-synuclein clumps — the protein aggregates that define LBD.
Crucially, the study clarifies how pollution interacts with brain biology: only mice capable of producing α-synuclein developed dementia-like brain damage after PM2.5 exposure — a mechanistic clue echoed by a Johns Hopkins release and Columbia Mailman overview. As Nature reports, PM2.5 doesn’t necessarily cause LBD from scratch — it can accelerate the development in people already genetically predisposed, notes clinician-neuroscientist Hui Chen (University of Technology Sydney – Nature).
Why millennials should care
PM2.5 is small enough to reach the bloodstream and brain, with established risks for heart and lung disease — and growing evidence for cognitive harm and dementia. See U.S. EPA: PM Basics, EPA: Health Effects, WHO: Air Pollution & Health, and a Harvard meta-analysis on pollution-dementia links (Harvard T.H. Chan School). Policy matters, fast: cutting fossil pollution saves lives and money within years — co-benefits quantified in recent modeling for the US and globally.
Eco Action steps that actually help
Drive electric, support clean transit

Tailpipe emissions are a prime PM2.5 source; electrifying cars, buses, and freight slashes exposure. EPA and NIH summarize health benefits; U.S. rules are tightening PM standards. From the region: EV adoption and smarter policy can reduce urban smog and climate pollution.

Get outside: “forest bathing” and brain health

Time in nature is linked with lower stress and improved cognition; experimental work shows 90-minute nature walks reduce rumination and dampen maladaptive neural activity.
