Not all aerosol causes harm. Indeed, some are very useful at treating diseases of not only the lungs, but of other conditions as well
In my latest explainer video, I introduce the topic of pharmaceutical aerosol. I discuss a bit of its history and some of the underlying advantages and disadvantages

I suppose there is some comfort in knowing that the people they've put in charge have no idea what they are doing. That'll help limit the damage.
Y'all they really just fucking highlighted the text black in word on the redacted Epstein files. At least for the digital text files anyway. You can just fucking copy and paste it elsewhere to read it LMAO. I just tried it because I was like there's no fucking way and shit worked flawless.

One of the reasons why I go so hard on science misinformation/disinformation, is that as a working scientist it is frustrating to see your research misreported to push an agenda.
For example, consider this piece of right-wing propaganda from The Telegraph that was just published

I’ve been watching about 2 decades of Jamie Christmas specials in preparation for the big day.
Question: why did it use to be so important to put butter under the skin, and now he doesn’t do it? What changed? This is a massive difference in technique, yet no reason has been given.
Help!

This question came up. While somewhat coy, it isn’t actually that simple to answer.
Given that I’m an “aerosol scientist”, I figured I take a crack at answering it.

Many things will affect how well a student will do in school. Some you can control, others you can't
One that affects every student (and teacher), and that we can control, is indoor air quality
In this video I walk through how and offer some solutions
