Neil deGrasse Tyson on Stem Cells
Question: Is stem cell research at the forefront of medical innovation?
DeGrasse Tyson: This… All this talk about investing in medical breakthroughs, predominantly, through the National Institute of Health, that‘s the primary sort of government agency for medical research. What I caution is… Fine, we all want to live healthy. That’s not even [here] to debate. But keep in mind that if you take a tour through a hospital and look at every machine with on and off switch that is brought into the service of diagnosing the human condition, that machine is based on principles of physics discovered by a physicist in a machine designed by an engineer. Nowhere in that equation was there a medical doctor or a medical researcher. And so, you can’t just fund one branch of scientific inquiry, you have to fund them all. Because these advances… For example, the MRI came from principles of physics discovered by a physicist who had no interest in medicine. That wasn’t his point. That wasn’t what drove him. Yet, it has this marvelous application that we could diagnose, release probe inside your body without cutting you open first. So the cross pollination of disciplines is fundamental to truly revolutionary advances in our culture. And so, you can’t fund any one thing without the other, [unless] you believe you were right on top of the solution when, in fact, you’re not.

Even the optimists among us would have to admit 2018 was a challenging year. The fractured world that became the focus of our 2018 Annual Meeting a year ago came under further pressure from populist rhetoric and rising nationalist agendas. At the same time, the urgent need for coordinated global action in areas such as climate change, inequality and the impact of automation on jobs became more intense.
Research by neuroscientists at MIT's Picower Institute for Learning and Memory helps explain how the brain regulates arousal.
The big day has come: You are taking your road test to get your driver's license. As you start your mom's car with a stern-faced evaluator in the passenger seat, you know you'll need to be alert but not so excited that you make mistakes. Even if you are simultaneously sleep-deprived and full of nervous energy, you need your brain to moderate your level of arousal so that you do your best.
You can use these to get ahead, no matter your age.
