Our conference paper that utilizes computational fluid dynamics in determining the optimal placement of indoor CO2 sensors has been presented by (Dr. Joules Lustro Julius Lustro) and published. Link here: dx.doi.org/10.5281/zenodo…

Fantastic review on chronic SARS-CoV-2 infections by virological superstars Richard Neher & Alex Sigal in Nature Microbiology. I’ll do a short overview, outline a couple minor quibbles, & defend the honor of ORF9b w/some stats & 3 striking sequences from the past week. 1/64

About a year and a half ago, I began designing a respirator with the goal of making it more comfortable and better fitting than a standard N95 mask. My concept incorporated an H14 filter and a battery-powered fan, all housed within the compact dimensions of an N95 mask. However,

With wildfires raging in California, we noticed that some manufacturers are advertising their small air purifiers as great options for dealing with wildfire smoke. However, most small air purifiers will be useless against wildfire smoke. Here is what you need to know 🧵

Latvia (pop. 1.9 M) has installed CO2 sensors in 14,000 classrooms to monitor indoor air quality in real time. Measurements are freely available at co2.mesh.lv/home/dashboard. A tremendous effort in transparency and prevention. Other similar initiatives: letsair.org/#early

Our fundraising campaign to develop a silent air purifier that uses off-the-shelf, non-proprietary filters has started! You can help us by sharing, making a contribution of any size or selecting a package that includes one of our DIY kits: igg.me/at/n8zLwkwyTbw…

You can now help North Box Systems create a silent PC fan-powered air purifier for schools that uses off-the-shelf furnace filters. Support their project here 👉 indiegogo.com/projects/polar…

I can't tell you how many times I've walked into a patient's room that was dark with small windows and just wished I could turn my ICU into this: It's not hard to do if there was a will...

The AirSpot Health CO2 monitor is a super portable device that can be used as a watch, keychain, or even be attached to your phone. This is definitely the most convenient CO2 monitor I’ve tried to date. Full review coming soon!

Particulate air pollution affects more than just your lungs. And your arteries. And your heart. Turns out, short term exposure can also affect brain function. theguardian.com/environment/20…

Another paper showing the safety of Far-UVC - onlinelibrary.wiley.com/doi/10.1111/ph… We're *extremely* unlikely to ever get a pharmaceutical solution that eliminates 99%+ of SARS-2 & multiple other airborne viruses simultaneously. But Far-UVC can do this. It's just physics.

A tumultuous 24-ish hours since our preprint was released yesterday. I mentioned that this was a fraught issue and I genuinely do understand that people have mixed feelings about the work. I wanted to take some time to respond to some of the concerns and comments that have 1/

I created a 3D printed prototype of the aesthetic edition of the 3Pro version 1.2. It retains the same size, is easier to install, and includes a PM2.5 sensor, a screen, and an app for phone control. Please disregard the color, as the final product will feature a different color.

This week, a math professor at MIT told me that incoming students are, on average, noticeably worse at math than they used to be. Harvard, of course, just added a remedial math class, Math MA5, "aimed at rectifying a lack of foundational algebra skills among students".

New hospital study: air purifiers cut airborne COVID by 98%. Rooms with HEPA ventilation had zero virus detected. Clean air is essential public health infrastructure — not a luxury. Study: sciencedirect.com/science/articl… #CorsiRosenthal #CleanAir #PublicHealth

Why have autism rates risen over time?🧵 I have just put out an article dealing with numerous misconceptions about this topic, and a complete explanation of why autism diagnoses have become more common. It starts with acknowledging that more kids are diagnosed than in the past:

Published today📣 Our nasal booster in the "Prime & Spike" vaccine works without adjuvants (which are needed to induce adaptive immunity but also cause inflammation). Dong-il Kwon 🇰🇷 Tianyang Mao Benjamin Israelow et al. asked how this is possible. (1/) nature.com/articles/s4159…
