90%  מהתרופות שעובדות בעכברים נכשלות בבני אדם - וה-FDA מגיב!

הFDA  החליט לאחרונה: ניסויים בבעלי חיים כבר לא חובה בכל שלב בפיתוח תרופות. במקום זאת, חברות יוכלו להשתמש בטכנולוגיות חדשניות כמו "איברים-על-שבב" - מודלים המבוססים על תאים אנושיים שמדמים פעילות של איברים ומחלות.⬇️

Great talk by @t8el.bsky.social at our econ theory seminar. As an added bonus, he publicly credited me for what he called two "Yannai tricks" in his slides:
1. Adding photos of his kids
2. Using memes
Happy to see my efforts of enriching econ with computer science techniques are bearing fruit!
