今天听了诺奖得主Karl Deisseroth的访谈。太炸裂了！简直像科幻小说。
科学家把单细胞绿藻中编码光敏蛋白的基因，导入动物大脑中特定的神经元。这个蛋白嵌入细胞膜后，就像给神经元安装了一个由光控制的开关。通过特定波长的光，就能精准控制这些神经元的活动，而不直接激活周围没有这个蛋白的细胞。
这项技术叫光遗传学，为研究大脑和探索神经系统疾病的治疗方法打开了全新的可能性。
谁能想到，一种单细胞绿藻，竟然能和大脑神经科学联系起来？
过去几十年，我们的教育和科研体系更强调专业化，鼓励人们在一个狭窄的领域里不断深入。但这个案例再次让我感受到跨领域思考与合作的重要性。更难得的，是那份不受专业边界限制的好奇心和想象力。
之前，我对AI可能给下一代就业带来的冲击，还有些担忧。
听了这个访谈，我反而乐观了许多。
他们这一代，将拥有前所未有的AI工具，去探索我们这一代人难以想象的世界。
他们最需要的，也许不是更高的ACT分数，而是永不枯竭的好奇心、天马行空的想象力、独立思考的能力，以及跨领域合作的领导力。
当然，扎实的知识基础依然重要。但学习不应该只是为了考试、升学和谋生，也应该是为了探索世界，满足好奇心。
AI这个超级工具，让知识更容易获取，让跨领域的探索变得更快、更容易，也让许多过去遥不可及的想法有了实现的可能。
对于一个对世界充满好奇的人来说，生在这样的时代，是一件多么幸福的事！
我马上分享给了我的孩子，他们这个周末是required weekend 不能回家：
I just listened to an interview with Karl Deisseroth, and it was absolutely fascinating!
One of the discoveries he helped pioneer sounds almost like science fiction!
Scientists took a gene from a tiny, single-celled green alga that produces a light-sensitive protein and introduced it into specific neurons in animal brains. This protein works almost like a light switch, allowing scientists to turn those neurons on or off using light, without directly activating surrounding neurons that don't have the protein. Imagine being able to control specific brain cells with light! This technology, called optogenetics, has opened up incredible possibilities for understanding the brain and potentially treating neurological disorders.
What fascinated me even more was the imagination behind this discovery. Who would have thought that something from a tiny green alga could help us understand the human brain? It took scientists from different fields, thinking outside the box and connecting ideas that seemed completely unrelated.
It reminded me how important curiosity and imagination really are.
For decades, education and research have emphasized becoming an expert in one particular field. But with AI, I think things are changing. Knowledge is becoming more accessible than ever, and curiosity, creativity, and the ability to connect the dots may become even more valuable.
One thing that impressed me was that Deisseroth mentioned how widely he reads, far beyond his own field. You never know when something you learn just for fun might inspire a completely different idea years later.
Your generation faces so many distractions, but you also have incredible resources that previous generations could only dream of. With AI, you can explore almost anything that sparks your curiosity, whether it's science, mathematics, literature, art, philosophy, or something you've never even heard of before.
I think AI will be especially empowering for people who are curious and willing to learn. The key is to use it to expand your thinking, not replace it.
And that's really what I want to share with you. You have so many talents and interests, and there's such a fascinating world out there waiting to be explored.
Don't feel that everything you learn has to serve a purpose, lead to a career, or become an achievement. Read something simply because it's interesting. Ask silly questions. Explore unfamiliar subjects. Follow an idea just to see where it takes you.
Learning doesn't always need a destination. Sometimes the joy of discovering something new is the greatest reward.
I hope you'll always keep your curiosity and imagination alive, and most importantly, have fun exploring this amazing world! ??
