Ionization can reduce pathogens in small chambers, but does it work in real life? Not according to our latest paper. We looked at airborne culturable bacteria in a lecture hall when an in-duct ionization system was on vs. off and found no differences.

Bipolar Ionization Did Not Reduce Airborne Bacteria in a Lecture Hall
Ionization treatment of indoor air has attracted attention for its potential to inactivate airborne pathogens and reduce disease transmission, yet its real-world effectiveness remains unverified. We e...

once at a science museum they had an exhibit that was 'this is what space smells like' and i think that's honestly one of my strongest memories of a scent? mostly dusty, but smoky as well. i might not remember it fully but even so

Like Star Trek. Anytime they want to do a plot with a shuttle crashing, the planet mysteriously has "atmospheric ionization" or some shit so the transporters don't work.

M104 is a spiral galaxy located about 31 Mly away in the constellation of Virgo.
It is a low-ionization nuclear emission region (LINER) type galaxy. This means that the galaxy has emission line, but those lines are predominantly from non ionized to low ionization atoms. #astronomy

Water lamps are sustainable, portable lanterns that generate electricity from saltwater or fresh water mixed with salt. These eco-friendly devices use ionization to provide up to 45 days of light, making them ideal for emergency situations and off-grid, coastal communities.

like most of them are pretty committed to getting fully closed loop systems minus needing to flush the water eventually due to ionization

"Get a photoelectric smoke detector" they told me. "It's better than ionization detectors" they told me.
You know what they didn't tell me? It'd have a red light flash every 30 fucking seconds 🚨
And unlike most electronics, I don't want to just put opaque tape over the light 🤬

The Tulip Nebula, also known as SH2-101, located 8,000 light years away in the constellation Cygnus. It is an emission nebula which means it emits its own light due to ionization from nearby young stars.

It's seriously been fucking with my sleep and I feel like the extra protection isn't worth a red flash every 30 seconds in my bedroom. Maybe I'll use them in the rest of the house and use ionization detectors in the bedroom? Or maybe there's non-flashing photoelectric detectors?
