At the behest of corporate lobbyists, Trump's CFPB will block states from erasing medical debt from credit reports.
This comes as the GOP allows ACA subsidies to expire – which could cause millions to go uninsured and medical debt to skyrocket.
A perfect storm of cruelty.

Quite a world when a federal judge has to call in a federal official to specifically tell him he can't use tear gas on children in Halloween costumes

125 MHz 1,4-difluorobenzene proton and fluorine multiplets appear first-order with equal J-couplings, even though the protons are not magnetically equivalent. Observed splitting of 6.08 Hz in both multiplets is close to the average of these couplings.🧪 #NMRchat #chemistry #benchtopnmr

A free and democratic society cannot silence comedians because the President doesn’t like what they say.
This is an attack on free speech and cannot be allowed to stand.
All elected officials need to speak up and push back on this undemocratic act.

It really cements Charlie Kirk’s reputation as a hero of free speech when his followers threaten, doxx, and get people fired for not “mourning properly.”
(Actually, it underlines what a scam that “free speech” routine was in the first place.)

Ossoff on RFK Jr: "Absolutely he should resign. And he never should've been confirmed to begin with... in any normal Senate, he never would've gotten so much as a hearing. This is someone who throughout his public life has embraced just about every piece of quackery & pseudoscience he's come across"

The somewhat tedious activity of pitting wild plums always requires loud music. One year it was Beethoven’s Ninth. Today it was Blue Öyster Cult. “…the only prescription is more cowbell.”

4-phenyl butyric acid is a non-endogenous aromatic fatty acid that has been approved by the FDA as adjunct therapy for urea cycle disorders.
Recently developed benchtop NMR spectrometers, such as our model QM-125, have drastically reduced in-house analysis cost of therapeutic small molecules.

Tuesday is Women’s Equality Day, marking 104 years since the 19th Amendment was certified. Maybe it’s time for Congress to recognize that the Equal Rights Amendment has been ratified. Thirty-eight states have ratified it. Do you know which ones haven’t?
