Others develop from certain trace vapours, for example when individual sulphuric acid and water molecules cluster as tiny droplets.

When they consume BMAA - tainted food or drink — be it bat stew, shellfish, or contaminated water — the molecule is not discarded; instead, it is taken up and deposited in the brain, forming what Cox calls a «toxic reservoir.»

For instance, when the level of dissolved nutrient molecules (e.g., sugar) in the cell's watery environment drops, water flows into the cell through osmosis.

Ulijn's gel is composed of two simple synthetic peptide derivatives: (1) a component that binds to copies of itself with high directional preference, resulting in the spontaneous formation of nanoscale fibers when the molecules are dissolved in water, and (2) a surfactant - like molecule that associates with the fiber surface and presents simple, cell - compatible chemical groups.

Indeed, the perfect solution already exists: a carbon - free fuel cell that strips combustible hydrogen from a molecule like water or alcohol and yields only water when it is burned.
