Q & A

What was the speaker's position at Yale University?

The speaker was offered a position as an associate professor of medicine and chief of scientific visualization in the department of medicine at Yale University.

What was the primary role of the speaker's job at Yale?

The speaker's job was to write algorithms and code for NASA to perform virtual surgery, preparing for astronauts going into deep-space flight and being kept in robotic pods.

What new scanning technologies were being used in the speaker's work?

The speaker was using new scanning technologies that allowed them to see things in the body that had never been seen before, including disease management and other aspects of the body's structure.

Why is the collagen structure in the cornea of the eye different from the rest of the body?

In the cornea, collagen changes its structure to a grid formation, which allows it to be transparent instead of opaque, unlike the rope-like structure found elsewhere in the body.

Who was the person working on the micromagnetic resonance imaging machine with the speaker?

Paul Lauterbur was the person working on the micromagnetic resonance imaging machine with the speaker, who later won the Nobel Prize for inventing the MRI.

What project did the speaker mention involving the development of a fetus from conception to birth?

The project involved scanning the development of a fetus from conception to birth using new technologies, for which the speaker wrote the algorithms and code.

What is unique about the development of the human heart at 25 days?

At 25 days, the human heart is just basically two strands, and it develops through a process similar to origami, folding on itself to eventually form a mature heart.

What is the significance of the trophoblasts in the development of the fetus?

Trophoblasts are clusters of tissue that come off the blastocyst and burrow into the side of the uterus, signaling their intention to stay and communicate with hormones to establish the pregnancy.

How does the speaker describe the complexity of the human body's development?

The speaker describes the complexity as beyond human comprehension, marveling at the biological mechanisms and mathematical models that guide the development without making mistakes.

What new studies is the speaker involved in regarding babies' brains?

The speaker is involved in two new studies that involve scanning babies' brains from the moment they are born, every six months until they are six years old, to observe how the brain's gyri and sulci fold and develop.

What does the speaker find remarkable about the woman's body during pregnancy?

The speaker finds it remarkable that a woman's body has the genetic structure not only to build her own body but also to become a mobile system that can nurture and treat the child with a kind of marvel beyond comprehension.
