New Technologies, New Surgeries

Question: What technologies are reshaping the surgical field?

Marc Bessler: So right now, just like you have an endoscopy, you have a flexible scope that goes there and brings light and visualization with it and a channel or two to put instruments down, that’s the technology we’re using for the most part to get in from a long distance away to reach to the organ we need to get to, you know, in a path that may not be a straight line and so we’re using right now, off the shelf instruments that weren’t particularly designed for the purposes we’re using them ultimately and we need to have things that can steer better, that can provide some rigidity once you get there and although they get there in a flexible manner, end up giving you some stiffness so you can work. We need to triangulate, right now the instruments come out like this and we’re used to operating like this, like with your hands. So we need to have technology that will allow us to come out and back towards the center so that we can work in a triangulated fashion and those technologies exist, they really need to be refined and brought to the market so they can be used for patients, not just on someone’s, you know, work bench.

From triangulation to finding new uses for current implements, Dr. Marc Bessler hopes to bid sutures farewell.

Remote learning vs. online instruction: How COVID-19 woke America up to the difference

Educators and administrators must build new supports for faculty and student success in a world where the classroom might become virtual in the blink of an eye.

  • If you or someone you know is attending school remotely, you are more than likely learning through emergency remote instruction, which is not the same as online learning, write Rich DeMillo and Steve Harmon.
  • Education institutions must properly define and understand the difference between a course that is designed from inception to be taught in an online format and a course that has been rapidly converted to be offered to remote students.
  • In a future involving more online instruction than any of us ever imagined, it will be crucial to meticulously design factors like learner navigation, interactive recordings, feedback loops, exams and office hours in order to maximize learning potential within the virtual environment.

Has science made religion useless?

Placing science and religion at opposite ends of the belief spectrum is to ignore their unique purposes.

Videos
  • Science and religion (fact versus faith) are often seen as two incongruous groups. When you consider the purpose of each and the questions that they seek to answer, the comparison becomes less black and white.
  • This video features religious scholars, a primatologist, a neuroendocrinologist, a comedian, and other brilliant minds considering, among other things, the evolutionary function that religion serves, the power of symbols, and the human need to learn, explore, and know the world around us so that it becomes a less scary place.
  • "I think most people are actually kind of comfortable with the idea that science is a reliable way to learn about nature, but it's not the whole story and there's a place also for religion, for faith, for theology, for philosophy," says Francis Collins, American geneticist and director of the National Institutes of Health (NIH). "But that harmony perspective doesn't get as much attention. Nobody is as interested in harmony as they are in conflict."

Supporting climate science increases skepticism of out-groups

A study finds people are more influenced by what the other party says than their own. What gives?

Politics & Current Affairs
  • A new study has found evidence suggesting that conservative climate skepticism is driven by reactions to liberal support for science.
  • This was determined both by comparing polling data to records of cues given by leaders, and through a survey.
  • The findings could lead to new methods of influencing public opinion.
