👋 Breastfeeding & infant feeding expert here! All babies need safe, accessible nutrition. Most people already want to breastfeed and 84% start out doing so but can’t realize their goals. What we need are *policies* that make it possible to breastfeed for all who desire to do so and…
RFK Jr: "All of the ingenuity of corporate America has not produced an infant formula that is superior in nutrition and all the qualities that we want to the infant formula that God made, which is the infant formula in a mother's breast."

I don't think the general public knows that law review articles for legal scholarship aren't peer-reviewed at all, just kind of edited by the (overworked and underappreciated) student journal clubs, and well, the future of the country can't rest on that.
The current SCOTUS majority is a bunch of sophists who like to dismiss evidence in favor of hypotheticals. They are spending enormous political capital trying to empower a guy that tried to overthrow the US government. If any good comes of this, hopefully it will radicalize people about SCOTUS.
The conservative justices have their talking point -- what if Congress turned every department into a multimember commission -- and it is totally absurd considering that has never happened under the existing law.

If we can magically find $12B for an agriculture bailout caused because of made up tariffs, we can find funding for trains, libraries, & clean energy. Btw the annual budget of the EPA is $9B. The whole thing! About the same with the National Science Foundation. Cut bad stuff, triple good stuff.
Not only can the country absolutely afford to do a lot more good things that help people– in housing, healthcare, infrastructure, and environment– there is no reason not to do it. Pretty simple: We should do big things that help people and not do things that hurt people. bsky.app/profile/cost...
How many times in your life have you heard a member of Congress or someone on TV say “we can’t afford it” when talking about something small but very important? It’s been happening my entire life. We can’t afford it? They’re putting seven times the annual budget of the EPA into immigrant detention.

Analogizing the EU to the Nazi regime is embarassingly ignorant of history, and it's shameful that our new national security strategy seems to say that those promoting international cooperation in Europe are bad and those trying to rehabilitate violent nationalism are good
The EU was created in by people who lived through WWII and saw political and economic integration as a means to bringing peace and stability to the continent.

It is being opposed by Putin, Musk and the others who support Neo Nazis in Europe.

It could take decades to recover from where we are.
My teen, who had dreamt of being an astrophysicist, just told me he wants to go to law school because, “Science isn’t going to be a priority in the US in the future…I don’t want a job where I’ll be constantly worried my funding will be taken away.”

Gutting. How many future scientists have we lost?

Y'all, I just wrote an answer to a question about the sensationalized news headlines circulating about the Chernobyl containment structure.

The bottom line is that there's a hole in the structure, which is not good, but it's not the end of containment, which some reports make it sound like.

🧵
The way this is being reported is extremely irresponsible.

There is a hole in the containment structure, about 10 feet across. No other damage is reported. That hole can allow some of the dusty radioactive material to escape.

That is what "can no longer do its job of containment" means.

On January 1, Illinois begins to regulate employer use of AI, making it a civil rights violation to use AI tools that result in discrimination based on protected characteristics in hiring, promotion, discipline, termination, or other employment terms and requiring notice of AI use. #AIBillofRights
Illinois becomes one of the few states to regulate employer use of AI. House Bill 3773 amends the Illinois Human Rights Act to make it a civil rights violation for employers to use AI tools that result in discrimination based on race, gender, age, or disability.
