Call to action: John Green on how to force corporations to change.
"they cannot make decisions that would harm the shareholders even when that would benefit the entirety of humanity...talking to other shareholders about how they're profiting off of price-gouging the wolrd's poorest people and those who serve them....The only way to get them to do the right thing is reputational harm"
Go listen, then sign the petition

100 years ago #OTD Edwin #Hubble mailed the light curve of a #Cepheid in Messier 31 to Harlow Shapley who allegedly (a report about his immediate reaction was only published many decades later; contemporary sources seem lacking) immediately accepted the existence of other galaxies - a timeline of events related to this key insight based on numerous sources: https://www.facebook.com/dan.fischer.393/posts/pfbid02D7dy3mNRVXa9fi8mWeY5q6KJrUnMcSPi62CYejCLy5ha2XPhH6wXJsNgN5aHLvcAl (corrections and additions, especially about other reactions, for the years 1922 to 1926 welcome).

It’s time for cheaper tuberculosis tests, #Danaher. It’s #TimeFor5. Lower the cost of tests for multi-drug-resistant TB and let’s save some lives. #Gubbins4Good #PatientsOverProfits #Cepheid

100 years (and a few weeks) ago the #Universe began to expand vastly as with the discovery of a variable star in Messier 31 which would turn out to be a #Cepheid astronomers began to realize that the Universe doesn't end at the edge of *our* #Galaxy. But the detailled history of how "VAR!" started this revolution is hard to figure out as I just learned: see https://www.facebook.com/dan.fischer.393/posts/pfbid02LW2BdFuucbe5GQrXDnHZuoCLEhi3ReHk2KEsYiRUqkJCJVsdxjXHdJrPayZ2kPp2l for what I could find out and which questions remain to be answered. Can you help? But with hard references, please!

Don't forget!!
Nerdfighteria is taking a deep dive this week looking at how tuberculosis has affected art! Its impacts are super visible, especially during Victorian times, when beauty ideals were shaped by the "consumptive" look that #TB gave folks (especially women) #PeopleOverProfits #danaher #cepheid #XTBNext -

Glad to see the public pressure campaign by #MSFAccessCampaign #TreatmentActionGroup #JohnGreen et al push #Danaher #Cepheid to provide their #tuberculosis tests at cost to communities most in need.
For background - a public plead by John Green:

#Danaher’s announcement is really great, but it’s like giving food to a starving person while charging them $50 for a bottle of water. XDR multi-drug-resistant TB tests need to be accessible to those who need them, too. #PatientsOverProfits #Cepheid

A follow up video about the #Tuberculosis tests that #Danaher #Cepheid are making obscene profits from.
Nota bene: Hank is a lot nicer than he could be.

Call to action for #tuberculosis tests: please watch the video, and realize that most of the research Big Pharma profits from is paid for with your taxdollars; they can make a healthy profit and get filthy rich, rather than making an obscene profit and murdering people through greed.

A 1.3% distance to Messier 33 from HST #Cepheid photometry: https://arxiv.org/abs/2304.00037 - the analysis finds "a distance modulus for M33 of μ = 24.622 ± 0.030 mag (d = 840 ± 11 kpc), a best-to-date precision of 1.3%."

The title of the song reminded me if this song:
- Goddess - #Cepheid
