Had a holiday photo taken with my buddy Protege @ucdavis.bsky.social So glad my office is close to the College of Agricultural and Environmental Science's horse barn area. The Donkey and the Engineering Dean Could be a great children's book! @ucdavisengineering.bsky.social

I am so excited. Our @ucdavisengineering.bsky.social rock band - The Technically Hip - has just added a saxophonist, and rumor has it that there may even be some cowbell in our future. www.youtube.com/watch?v=QnzW...

Great list, @meganranney.bsky.social! I will add: * Higher education 🏫 * Science ⚗️ * Great colleagues * Music 🎸 * Dogs 🐕 * Tofu

Nov 21st Update: NWSS is back! After what may have been the lowest transmission rates since 2021, we are seeing rises again. Expect this to accelerate into the holiday season, especially in MW&NE Estimates: 🔸150,000 new inf/day 🔸~1 in 220 currently infected 🔸~1 in 550 are significantly infectious

Egret and its reflection. @ucdavis.bsky.social arboretum

The U.S. government is now inarguably spreading medical disinformation that is going to kill babies preferentially. Period. This is an INTOLERABLE. UNPRECEDENTED. DANGEROUS. ATTACK. ON ALL OF US.

We are educating future engineers & doing research that will better society & the planet, and also rocking out! I am so proud that the @ucdavisengineering.bsky.social has its own rock band, the Technically Hip. Check out the rockumentary link in the story below. www.ucdavis.edu/magazine/uc-...

1/ H3N2 that’s circulated worldwide this year “acquired 7 new mutations over the summer,” Antonia Ho, of Scotland’s U of Glasgow, said. That “means the virus is quite different to the H3N2 strain included in this year’s vaccine,” she said. www.nbcnews.com/health/healt...

We recently saw a randomized trial of exercise markedly improve cancer disease-free survival www.nejm.org/doi/full/10..... How can this be explained? www.sciencedirect.com/science/arti...

End of day rainbow over @ucdavis.bsky.social today.

mRNA vaccines help vs cancer Our @scifri.bsky.social conversation, with transcript www.sciencefriday.com/segments/cov... Remarkable improved survival data and mechanism reviewed here erictopol.substack.com/p/how-mrna-v...

Awesome lineup. Wish I could attend.

🔸️Early data suggests we could be in for a worse than normal flu season, brought on by a cluster of escape mutations in H3N2 this year that may lift the Re from 1.2 to 1.4. We are starting to see an uptick in the US. Data from BIOFIRE.

The wreck of the Edmund Fitzgerald happened 50 years ago today. Gordon Lightfoot memorialized the tragedy in a haunting song. Bob Dylan once implied that Gordon Lightfoot was the greatest songwriter of all time. He was certainly one of the great ones. www.youtube.com/watch?v=tV9P...

Grew up a Dodger's fan & sustained my allegiance through the years out of memory of my father's love for the Brooklyn & later Los Angeles Dodgers. I also loved going to Blue Jays games in the early 1990s while living in ONT. Blue Jays played like champs. Respect to both teams for a GREAT series.

No matter who wins, this World Series is one of, if not the best, of my lifetime. Wow!

Getting COVID twice doubles risk for long COVID in kids. www.medscape.com/viewarticle/...

We need the help of chimps.

Oh, the (very sad) irony. www.washingtonpost.com/health/2025/...

It’s been obvious now for years for Covid-19, but this adds to the evidence for other viral infections.

Alrighty, ready to see something really cool? (and maybe a little nauseating) The evolution of Hurricane Melissa's mesovortices at peak strength.

Please post a photo of your Corsi-Rosenthal Box if you are decorating one or more for Halloween. @crfoundationus.bsky.social

Defaulting to surgical masks in health care settings in 2025 is one of the most dissapointing examples of reluctance to change despite overwhelming evidence. Even defaulting to KN95 style would significantly increase protection of the most vulnerable. Infuriating inertia in the HC industry.

If you are able to, please contribute to your local food bank this week

This Dodgers / Blue Jays game may not be over until Halloween. Great game, but something's got to give.

Dry dusting is just moving dust around. I use a spritz of HOCI on my dust cloths. It's amazing how little dust forms especially on the ceiling fans when the corsi box is running pretty much running 24/7. The difference is night and day. When you have fur babies a corsi box is a must.❤️

1/ Excellent article and quotes by @ucdavis.bsky.social alumnus @tomgillpredicts.bsky.social regarding Valley Fever, "the west's Lyme disease." Valley fever is caused by inhalation of airborne fungal spores from the soil. This article is worth a read. More (4 parts)....

Very important findings. For a society increasingly absorbed in sports gambling, betting your health and life on vaccines is a very smart bet.

Portable air filters clean indoor air from smoke, dust, pet dander, viruses, and more. They are cheap & simple to make — I’ve built several — and nearly silent to run. *There is no downside.* Should be in every workplace, community space, school, daycare, medical facility, & home.

Gift from beyond Wonderful new posting of a #TragicallyHip session on a Dutch TV station in 1997. Incredibly tight. Amazing versions of Scared & Springtime in Vienna. Their screaming from the rooftops, "We live to survive our paradoxes." #StillMissGord www.youtube.com/watch?v=djUu...

Same!! And I'm in southern California and they're saving my lungs during fire season!

Thanks for sharing this, @larrynlarryshow.bsky.social.

In our short existence, The Corsi-Rosenthal Foundation has issued 58 grants providing healthier indoor air to 30,000 ppl. The Foundation aims to substantially increase these benefits to under-resourced schools over the next several months. Please consider helping us: givebutter.com/buildabox2025

Anti-science bills hit statehouses, stripping away public health protections built over a century www.statnews.com/2025/10/22/a...

We have two active data sets; 🔹WWScan wastewater 🔸BIOFiRE positivity Both suggest we are now near multi year lows for transmission. I'd expect this to last for another month before Thanksgiving gives it a boost up.

My buddy giving some side eye of disapproval for another selfie with the dean of engineering. Such a good donkey.

Brooklyn: you are most likely smelling the fire in NJ or MA. If you can smell it, the particulates are getting g in your lungs. Today’s a good day to wear a mask outside and build a Corsi Rosenthal box. Plans below. They really help. 1/x

Industry leader Diane Bryant speaks on value extraction of AI with many great examples. UC Davis AI Center in Engineering Innovation Showcase and Prem Jain Symposium.

Prem Jain kicks off our first UC Davis AI Center in Engineering AI Innovation Showcase and Prem Jain Symposium. Great turnout of faculty, students and industry leaders.

Thrilled that our College of Engineering and institution will be major contributors to this important and potentially transformational effort to make buildings healthier for occupants and those they interact with outside of those healthier buildings. engineering.ucdavis.edu/news/federal...

Two friends and ex-colleagues at UT Austin found an old student newspaper article and sent it to me. Everything pre-COVID seems like a lifetime ago. This image in the article was from 2005, before having to worry about my beard giving a poor seal on a respirator. Oh, to be 20 years younger again.

Want to get [FREE] Corsi-Rosenthal Boxes in your child's school this year? We've created an email you can share with the school principal to make the process easier. You can access it through the link on STEP 2 of our grant process. corsirosenthalfoundation.org/apply/ Please share!

With the chaos at the CDC and the wildfire smoke, seems like a good time to repost a 4th grader teaching how to make a Corsi Rosenthal box from duct tape, four filters, and a box fan. youtu.be/H2YELPNsImk?...

I really wish the schools had invested heavily in indoor air quality stuff. Missed opportunity. A corsi-rosenthal box in every corner!

Tactical Technical Communication as Expert Communication: Strategic Ethos in Corsi-Rosenthal Boxes "Throughout the COVID-19 pandemic, WHO and CDC incorrectly [🤬] made safety recommendations based on droplet transmission ..." so REAL experts & better-educated citizens stepped in.
