You’re alive right now… at least I’m pretty sure you are. But you’re not TOTALLY alive. Bits of you are always breaking down, being thrown out, and being replaced. Even right now, parts of you are dying. Some of your cells even died...

Hank shares some developments in cancer research, from new insights into the behavior of zombie cancer cells, to a new method that uses nanotechnology to kill cancer from within.

For a respiratory disease, COVID-19 sure seems to affect more than just the respiratory system. Scientists think the receptor ACE2 is to blame.

Paul Andersen explains how genes control the timing and coordination of embryo development. Seed germination initiates the discussion of cell differentiation. The SRY gene and genetic transplantation shows the importance of embryonic...

Apoptosis and the Physiology of Caspases

It doesn't matter what disease you are talking about, it can be attributed to one of 5 causes. Yes, only five. In this video, Leslie talks about the 5 causes of altered cell biology (disease).

DNA damage is inevitable. But what happens inside the nucleus when the DNA becomes damaged? Here we discuss the biochemical processes that occur and how the cell decides whether to attempt DNA repair or undergo apoptosis.

We just learned about electron microscopy, so what was the next major innovation in microscopy in the 20th century? That would be fluorescence microscopy, of both the widefield and confocal varieties. How does this work? What is...

Cancer is the ultimate expiration date for biological life. But what is it? How does it occur? Is there anything we can do about it? Let's take a brief look at this incredibly complex issue.

Jul.23 -- Jennifer Rohn, principal research fellow at UCL, discusses coronavirus testing, and the impact Covid-19 has on younger patients. She speaks with Bloomberg’s Francine Lacqua on “Bloomberg Surveillance.”
