A study by University of California, Riverside, scientists has found that two toxic chemicals can form when the main ingredient in most e-cigarette fluids is heated, and that these compounds can harm human lung cells. The researchers characterized the toxicity of methylglyoxal and acetaldehyde, both known toxins that can be generated during the heating of vaping liquids containing propylene glycol. …

These mysterious “fireworks” aren’t lighting up the night sky — they’re computer simulations from a recent paper on mixing fluids that don’t want to mix. Researchers mapped out how two immiscible fluids (two fluids that do not mix, like oil and water) with different viscosities can create “fingers” when they interact. They created different patterns by alternately injecting the fluids …
