What’s in a Flush?

Flushing a toilet produces a cloud of tiny, inhaleable aerosol droplets, as we’ve seen before. When the flush includes pathogens, those droplets can become seeds for infection. A new study tries to synthesize the literature on this health threat.

Unfortunately, that’s easier said than done. Because previous studies have varied widely in their conditions–what toilet shape, how large a flush, microbe type, pathogen concentration, lid/no lid, sampling parameters, and so on–it’s difficult to sort out each factor’s impact. Across the studies they surveyed, however, the team made two observations.

First, the higher the concentration of microbes, the higher the post-flush aerosol concentration. Similarly, a larger flush volume (creating a more energetic flush) also raises aerosol concentration. That higher aerosol concentration gets more disturbing in the context of one of their other findings: that some toilet flushes launch aerosols to the breathing height of an adult. Kids–whose shorter height places them closer to the seat–get even more exposure.

To really pin down how to design our bathrooms to minimize disease transmission, we’ll need more studies, and the authors pinpoint what characteristics future researchers need to measure and report. In the meantime, err on the side of putting the lid down before you flush! (Image credit: E. Wilcox; research credit: L. Adiyani et al.; via Gizmodo)

What happens to a virus as an aerosol droplet dries?

Instead of behaving like rigid shells, viral capsids appear mechanically adaptable. Tracking these nanoscale shape changes could help explain how some viruses remain infectious after rehydration.

One of the reasons for the #heatwaves we are experiencing is, paradoxically, that Europe has implemented policies against #microparticle #pollution: our air is cleaner than in China or the US, where a portion of the sun’s rays are blocked by #aerosols. This clearly demonstrates the dangers of #geoengineering, because if we start, we’d be condemned to continue forever.

Furthermore, the reduction of air travel could further worsen the situation for Europe, as we already saw during COVID-19.

Drying Out Microbe-Filled Droplets

Ocean sprays, coughs, and sneezes are just a few of the ways that droplets full of bacteria and salt can get aloft on a breeze. How do these bacteria stay viable even as their droplet evaporates? That’s the question behind this video’s research.

When a bacteria-laden droplet or a salt-laden droplet dries, the evaporating droplet’s contact area shrinks, leaving behind only a concentrated lump of bacteria or salt. But when droplets contain both salt and bacteria, the drying droplet’s contact line gets pinned, leaving a larger area stain. The bacteria’s presence seems to promote crystallization of the salt, which–in turn–traps water in isolated spaces, perhaps helping the bacteria stay viable longer. (Video and image credit: R. Ran et al.)

These stratospheric #aerosols acted as a massive planetary mirror, increasing the Earth's albedo. They scattered incoming shortwave solar radiation back into space while allowing longwave terrestrial heat to escape, causing abrupt cooling. This dimming caused widespread Eurasian crop failures for 18 months, proving that while nature has powerful levers like volcanic forcing, none are positioned to force modern temperatures upward.

Bubble bursting changes dramatically when bubbles have neighbors. In dense rafts, collapsing cavities produce thinner, faster jets and droplets up to 5× smaller than isolated bubbles.

A collective effect that could reshape how we model sea spray aerosols.
