Leavitt: "I think it's frankly ridiculous that anyone in this room would even suggest that President Trump is doing anything for his own benefit. He left a life of luxury and a life of running a very successful real estate empire for public service."

This isn’t even primary school-level economics.
Trump: "We already made a great deal. We're not doing business with China right now. We lost $1 trillion with China last year, so if you're not gonna do business with them, you're not gonna lose $1 trillion."

I’m sorry but if your students use AI to write papers and you use AI to grade them zero school is happening. You are running together on a hamster wheel
Why even have a brain, any ideas, any ability to express them, any kind of communication with other people, any desire to solve problems or invent anything, any reason to learn, any use for your eyes or your heart, or any reason to teach or create

If you use AI during your degree then your degree is completely worthless.
Even accepting the premise that AI produces useful writing (which no one should), using AI in education is like using a forklift at the gym. The weights do not actually need to be moved from place to place. That is not the work. The work is what happens within you.

This isn't even close to what America has lost. It is alone. No friends. Nobody will ever trust it again. Every interaction with other countries will be transactional. There is no goodwill. You will pay and pay and pay and we will all be poorer.
This is painful, and saddening, and embarrassing. I feel like we're losing a member of the family - and for no good reason other than that some Americans wanted another season of the worst reality TV show in history.

To help master apolipoprotein B, please obtain the very recent NLA Statement on apoB as well as these earlier statements to see how long the experts (clinicians and laboratorians) knew apoB was the critical metric. Anyone practicing CV care should be very familiar with these documents.

It’s not ageing, it’s ageism. If we all want to look forward to an older age without limits, we need to notice it, challenge it, change it.

Does hearing about ageism shock you?

Research has found that multi-generational teams are more productive and innovative, and we know that older workers bring incredible value to workplaces.

Structure of apoB & its binding to LDLR has been solved thanks to the NIH lipid team, led by Alan Remaley & Mart Reimund. ApoB consists of beta sheet & alpha domains, which firmly bind to LDL. 2 LDL receptors act as dimers to remove two LDL particles. www.nature.com/articles/s41569-025-01128-z

The great @nih_nhlbi division of lipids/vascular biology has radically changed what we have believed: For hepatic LDL clearance from plasma to occur, TWO LDL particles aggregate with the help of TWO LDL receptors functioning as dimers and then internalization occurs. doi.org/10.1038/s415...
