This podcast is supported by the Icon School of Medicine at Mount Sinai, one of America's leading research medical schools.

Icon Mount Sinai is the academic arm of the eight hospital Mount Sinai health system in New York City.

It's consistently among the top recipients of NIH funding.

Researchers at Icon Mount Sinai have made breakthrough discoveries in many fields vital to

advancing the health of patients, including cancer, COVID and long COVID, cardiology, neuroscience, and

artificial intelligence. The Icon School of Medicine at Mount Sinai, we find a way. Morgan State

University, a Baltimore, Maryland,

Carnegie R2 doctoral research institution, offers more than 100 academic programs and awards

degrees at the baccalaureate, master's, and doctoral levels, is furthering their mission of

growing the future leading the world. Morgan continues to address the needs and challenges of the modern urban environment.

With a four-year quadrupling of research, more than a dozen new doctoral programs,

and eight new national centers of excellence, Morgan is positioned to achieve Carnegie R1

designation in the next five years.

I'm Sarah Crespi. First up this week, measuring oxygen in the ocean using sharks. Contributing correspondent Warren Cornwall joins us to talk about a group of researchers putting data logging tags on sharks in order to study how climate is affecting oxygen levels in some of the ocean's darkest depths.

After that, what can 4 billion-year-old minerals teach us about chemistry on the early Earth?

Producer Megyn Cantwell talks to geochemist Dustin Trail about using minerals called zircons

to investigate the chemical properties of the early hydrothermal pools where life began.

Things are changing in the world's oceans. You might have heard of these things called marine heat waves or ocean acidification. They're on the rise.

They're bad for ocean life.

Another shift that's being seen now is ocean deoxygenation, the loss of dissolved oxygen
