TIL that lactose free milk is made with reverse osmosis. My husband and I had assumed it was done with enzymes (lactase).
How do they separate out the lactase? Is it a 2-step/membrane process to isolate molecules of exactly 1 size?

NEW: In light of widespread allegations of civil rights violations arising from Trump's immigration crackdown, Democrats are renewing efforts to pass legislation to hold federal agents individually accountable:

Democrats target federal officials accused of civil rights violations in new legislation
Lawmakers are launching a new effort to close a legal loophole that means federal officials, including law enforcement agents, cannot be sued for constitutional violations.

Not that he cares about facts, but 92% of Medicaid recipients are working or fall within an exempt category, and thanks to the Personal Responsibility and Work Opportunity Act (🤮), immigrants generally have to wait 5 years to enroll in Medicaid.

Secretary Kennedy, speaking to a bipartisan group of governors, has mixed up Medicare and Medicaid, and implied the people who will lose the latter are either unauthorized immigrants, dual eligible, or people who “don’t want to get a job.”

I caught Mitch McConnell earlier today and tried to ask him about the CDC promoting the lie that vaccines cause autism.
He voted against RFK Jr.'s confirmation.
But as is always the case, McConnell, a polio survivor, refused to answer questions.

Literally none of the economic issues we face are due to undocumented immigrants.
Meanwhile, this is verbatim Nazi propaganda being pushed out by the US Dept of Homeland Security.
The Trump regime is a fully fascist regime. They're not attempting to hide it in any capacity. This is who they are.

Induced demand to fill prison cells
I feel like the more important takeaway from this article is the need to stop building new prisons and start getting rid of old ones rather than just where new prisons are built
The construction of prisons in rural areas can create relationships in which residents ultimately become engulfed by incarceration. “The prison almost begins to imprison the community in a way,” says a prison researcher.

This is a man whose wife was SHOT IN THE HEAD having to act even-keeled when the President of the United States tries to incite violence against him. Trump has to go, right now.
I've had a missile blow up next to my airplane, been shot at dozens of times by anti-aircraft fire, and launched into orbit — all for my country. I never thought I'd see a President call for my execution.
Trump doesn’t understand the Constitution, and we're all less safe for it.

Only 48% of Republicans believe that vaccines prevent serious illness, while 80% of Democrats do.
