The speaker started their talk by saying the method might seem immediately problematic, but gave a number of reasons it was ultimately likely to be safe. 15 minutes later it was time for questions.

And so I asked my question (paraphrased): "so imagining you did this, what targets would you try to validate the approach?"

The room stifled their laughter and the speaker looked at me like I had just advised an entire nation to drink bleach.

I'll avoid specifics: I don't want to put someone "on blast."

Fundamentally it was a talk about a possible therapeutic treatment. The system was a novel way to deliver a therapy that was risky, but held great promise. Clinical trials were a decade away, assuming research validated its promise.

I thought it was neat and innovative.

Maybe the most impactful talk I've seen in the last few years was a simple weekly talk by a dept post-doc.

The article I just shared (https://fediscience.org/@MarkHanson/110489681649296930) reminded me of this talk... thinking about science exploration...

What was special? I asked a question that got laughed at by the speaker and room. I've wondered ever since whether that was because I was just ignorant? Or was everyone else just creatively restrained? I still don't know the answer... 1/n

As with organ transplants, stem cells trigger an immune response when used in medical treatments, potentially leading to rejection of the cells.

To prevent this, Sana Biotechnology scientists have developed stem cells with removed HLA markers that survived uninhibited in rhesus macaques for months.

This opens up whole new prospects for medical treatment of organs and tissues.

Over in the bad place, Elon Musk this week re-platformed a Unite the Right nazi and a white supremacist who promotes accelerationism and says we should celebrate mass murderers like Dylann Roof and Brenton Tarrant. This comes amid an “unprecedented” rise in hate speech, and it’s creating a national security crisis that no one is prepared to address.

For brain researchers who are more genetically/molecularly/cellularly inclined ...

What are you most excited about along a timeline of the next next 10-20 years or so? Is it, say, the ability to manipulate DNA in living creatures (eg CRISPR), leveraging the immune system to tackle disease via antibody based therapies (like the new Alzheimer's drugs), cell type atlases, or something else altogether?
