Testing Athletes for Steroids

Question: Do you test athletes that use performance enhancers?

Gary Wadler: Well, there are two- first of all, to try to detect the abusive substances, we use basically body fluids and the classic body fluid has been urine. Not everything shows up in the urine. One such example, for the most part, is human growth hormone. In fact, less than two-tenths of one percent of the human growth hormone in your body ever shows up in the urine. And so people have spent a lot of time and money trying to develop a urine test. And Major League Baseball and the National Football League have contributed some dollars to try to do that as well, although over the last ten years have been five and ten million dollars have been spent in trying to develop a test for human growth hormone. Well, the conclusion was after a long series of meetings of experts and so on that the only available body fluids in which you can detect human growth hormone is blood. And so that is now part and parcel of the international schema for detecting the abuse of human growth hormone. Unfortunately, Major League Baseball and the National Football League are adamant in not having blood tested, which guarantees that there’s no way to detect that except in some sort of investigation, which has been the case.

Leonardo da Vinci could visually flip between dimensions, neuroscientist claims

A neuroscientist argues that da Vinci shared a disorder with Picasso and Rembrandt.

Christopher Tyler
Mind & Brain
  • A neuroscientist at the City University of London proposes that Leonardo da Vinci may have had exotropia, allowing him to see the world with impaired depth perception.
  • If true, it means that Da Vinci would have been able to see the images he wanted to paint as they would have appeared on a flat surface.
  • The finding reminds us that sometimes looking at the world in a different way can have fantastic results.

Education vs. learning: How semantics can trigger a mind shift

The word "learning" opens up space for more people, places, and ideas.

Future of Learning
  • The terms 'education' and 'learning' are often used interchangeably, but there is a cultural connotation to the former that can be limiting. Education naturally links to schooling, which is only one form of learning.
  • Gregg Behr, founder and co-chair of Remake Learning, believes that this small word shift opens up the possibilities in terms of how and where learning can happen. It also becomes a more inclusive practice, welcoming in a larger, more diverse group of thinkers.
  • Post-COVID, the way we think about what learning looks like will inevitably change, so it's crucial to adjust and begin building the necessary support systems today.
