Why I’d Love to Be a College Student Again
We all want to be young again, but I’ve rarely been as envious of young people as I was during my recent visit to Caltech.
Touring the campus, I was struck by what an amazing time it is to be a student at an institution like Caltech. In every field—from engineering and biology to chemistry and computer science—I learned about phenomenal research underway to improve our health, find new energy sources, and make the world a better place.
What’s exciting about this research is that if you’re a U.S. citizen you can thank yourself for many of the incredible projects on campus. That’s because much of the work is made possible by U.S. government investments. It’s your tax dollars at work and they can reap huge returns.
People often think that the U.S. spends a huge amount of money—perhaps too much—on R&D. In fact, all U.S. R&D spending accounts for less than 1 percent of national income.
I’ve written before about the importance of government investment to jumpstart innovation. Government-backed research in universities and labs leads to new ideas and technology that build new businesses, create jobs, and strengthen our overall economy.
But those big, life-changing discoveries and innovations—from the cancer cures to moonshots to solar cells– often get their start as an experiment in a university lab, an equation sketched on a professor’s blackboard, or a student asking, “What if?”
A new idea is a fragile thing. It needs allies to nurture it. Government R&D investments provide that important support. Without it, we would have fewer scientific breakthroughs.
Let me give a couple examples of why this is so important.
Some of the most exciting research I learned about during my visit was from Caltech scientists working on identifying possible treatments for neurodegenerative diseases such as Parkinson’s and Alzheimer’s. All of the researchers received government R&D funding.
Today, about 5.2 million Americans aged 65 have Alzheimer’s, but the number is expected to grow dramatically in the decades ahead. According to some estimates, by 2050, there will be a million new cases every year and the economic burden to the nation to care for those with Alzheimer’s will likely quadruple to $735 billion.
These are projections based on what we know about the disease today. Currently, there is no cure or effective treatment available.
But two of the researchers I met at Caltech are experimenting with innovative approaches to fight Alzheimer’s.
Bruce Hay, a professor of biology, shared his research on how he hopes to turn back the aging clock, delaying the impact of Alzheimer’s.
Bruce’s research focuses on the role of mitochondria and mitochondrial DNA in the aging process. Mitochondria are the cell’s powerhouses, converting the chemical energy from the food we eat into a form our cells can use called adenosine triphosphate or ATP.
As we get older the mitochondrial DNA mutate, leading to cell dysfunction, and eventually cell death. Bruce’s goal is to prevent the process by cleaning out the mutated mitochondrial DNA, allowing us to feel younger.
Our bodies have a natural quality control process for removing mutated mitochondrial DNA, but it’s very inefficient. Bruce is researching ways to stimulate the removal of mutated mitochondrial DNA. He envisions a day when people would go to a spa for a mitochondrial cleanse to rid their bodies of the mutated mitochondria, helping to keep them feeling younger. I think all of us would want to sign up for a treatment like this.
I also met with Viviana Gradinaru, an assistant professor of biology and biological engineering. Viviana is working on developing new tools and methods for understanding how the brain works and how that knowledge could be used to treat people suffering from neurodegenerative diseases.
Much brain research, she told me, focuses on cellular and molecular pathways of neurodegenerative diseases. This is important research but it ignores the role of electrical signals in brain function.
Viviana has dedicated her career to exploring this area. She’s currently investigating deep brain stimulation, which is the use of electrical stimulation to treat the most debilitating symptoms of Parkinson’s disease. While it’s effective, there is not a lot of understanding about exactly how it works or how it might be applied to treat other diseases such as Alzheimer’s. She’s also exploring the use of light to stimulate the brain, a field called optogenetics.
Maybe the most amazing research is her work to create see-through tissue to visualize neural circuits. This innovative technique will help with our understanding of the brain and how various diseases might impact it.
Finally, I had a great conversation with Dianne Newman, a microbiologist who is working on a better understanding of cystic fibrosis, a genetic disorder that impacts the lungs. Dianne has a unique background in environmental engineering, Earth science, and geobiology. She’s using her diverse interests to carve out a unique area of research into the Earth’s ancient bacteria and how it might help our knowledge of bacterial communities living in low-oxygen environments. These studies are helping us understand multidrug resistant pathogens that infect cystic fibrosis patients. Our foundation is interested in exploring whether any of her research might also apply to our understanding of tuberculosis.
I ended my visit to Caltech with a Q&A session with students. You can watch the video here. One student, a computer science and chemistry major, asked me which areas in science and technology are going to impact society and the world.
It was a great question but I found it hard to give him an answer. From what I saw at Caltech, there is incredible new research underway in every field. Any one of these disciplines would be enough to keep me excited for a lifetime. As I told the students, “The amount of innovation and the pace of innovation—contrary to what some observers say—I believe is faster today than ever.”
With continued government support, the number of amazing new discoveries at our universities will grow, as will their benefits.

7 年To whom it may concern, My name is Steven Wentz. I am a doctor of physical therapy in Ohio here in the United States. Over the last several years I have been fortunate to see the world through a different lens than most. I have traveled to Mexico, Peru, El Salvador, a couple Native American reservations, and lastly but certainly not least Haiti. I served as a clinical instructor for international service and learning on the majority of these trips. What I came across was very interesting. The majority of the places above have formal physical therapy services offered. The location that does not was found in Haiti. There are fantastic expeditions through Haiti with regards to life changing and saving surgeries performed by non-native physicians. Recently there has been a push to get native born individuals trained and educated in order to improve the infrastructure with regards to medicine. That however is not being carried over into the world of physical therapy. I currently work for a physical therapy company called Drayer Physical Therapy Institute. An organization who has its basis in helping every patient regardless of standing in life. We even have two executives that are on boards for Haiti and Jamaica medical organizations. I am fortunate to be going to Haiti in a few weeks on a physical therapy trip. That being said, I have an idea to help build infrastructure and improve the quality of physical therapy services within the country. I would like to see a network of students and professionals regularly going to Haiti as part of their education and professional careers to educate local people in the practices of U.S. based physical therapy in order to maintain the continuum of care beyond the life altering surgeries. As it stands the people are reliant on inconsistent group trips that provide a week of therapy or so, and then the people are left without again. By working with U.S. colleges and Universities and willing professionals we can establish a network of physical therapy clinics, and possibly an international school for the betterment of the Haitian infrastructure and to promote the continuation of care. too often we are sent to countries that do not need periodic help, but that require sustainable education for their future. By establishing an international school of physical therapy in country we can fill a gaping void in the medical care as well as improve the countries sustainability and bring to it a novel industry,. I realize that much of what i have said has been jumbled. But I see a real opportunity to improve a devastated situation, and I am motivated to create the necessary interactions to make this happen. I look forward to further sharing my vision with the Bill and Melinda Gates Foundation, Dr. Steven Wentz, PT, DPT

7 年I totally share same thoughts and feelings. Being 10 years of conventional engineer, now I am very excited about researchs going on all around the globe, but I find it difficult to join those blessed team of scientists due to family circumstances.... Thanks to development of technology, it will ve easier and easier day by day to support scientific improvements from distance at least in theoritical science.....
