Select boomers and millennials are looking for the same home but the former is often coming to the market equity rich and less price/rate sensitive than the latter. This has allowed boomers to overtake millennials as the top buyers in 2022
This was an absolutely mindblowing point from @AliWolfEcon I hadn't thought about before. Lots of people talk about how the housing market will get looser as Boomers age/die. But what if they're making the hottest housing markets even worse right now? bloomberg.com/news/articles/…

You can now track CA flu cases & hospitalizations in your county and region with the new flu feature on CalCAT: calcat.covid19.ca.gov #FightFluTogether

If UC actually bargained in good faith, we would have a @UAW5810 contract after over a YEAR. I would have had *8 weeks* of leave with my infant, instead of just 4 Daycare & transit support Instead, I strike - so future parents have it better than I did.

Fundamentally the “earn to give” philosophy of effective altruism is about reallocating private resources toward public goods. Make money so that you can fund altruism. But we actually have a way less sexy, way more scalable way of doing that, called “taxes”.

Very proud of our modeling team for adding flu projections to our CalCat site, you can look at by county, region or statewide! We’re seeing an early flu season so get your flu vaccine now if you haven’t already!
DYK: You can track CA flu cases and hospitalizations in your county and region. Check out the NEW flu feature on CalCAT by going to: calcat.covid19.ca.gov/. CDPH recommends the annual flu vaccine for everyone six months of age and older to reduce the risk of getting the flu.
Since 2020, the @MIDAS_Network coordination center has been supporting the #covid19scenariomodelinghub's projections for trajectories of the COVID-19 pandemic under alternative possible futures. The scenario modeling team has now moved on to flu... fluscenariomodelinghub.org

Our health care heroes continue to do the impossible and remain strong during the fight against #COVID19, but together we can help reduce the stress on our health care system by doing what’s possible: vaccinating and boosting, wearing a mask, and staying home when sick.

This echo chamber promotes provocative statements and a rush to be first rather than correct (or even just well supported by the evidence). It elevates those who chose a stance and defend it absolutely. It favors frequency of message over novelty of content 2/

.@CAPublicHealth, @SF_DPH & @UCSF have detected a case of the Omicron variant. As we continue to learn more about Omicron, there is no reason to panic but we should remain vigilant. We know how to protect ourselves from COVID - get vaccinated, get your booster & wear a mask.

So, the US has confirmed its first #omicron case. And because you have all been following my tweets, none of you are gonna act surprised now right? RIGHT?

Replying to @EricTopol
How can we treat J&J recipients this badly? We said take the first available vaccine, and they did. Where is their follow-up?

1. Good morning. #ACIP is meeting today and tomorrow. Today, at least, I will be live tweeting. @US_FDA has not yet indicated what it is going to do with Pfizer's application for a booster license. So it's really completely up in the air at this point how this turns out.

An update on genomic surveillance in the US and spread of the Delta variant (PANGO lineage B.1.617.2, Nextstrain clade 21A). At this point, 95% of viruses circulating in the US are "variant" viruses that have been designated as "Variant of Concern" or "Variant of Interest". 1/12
