Episode notes

The protein ApoE codes for can be trafficked out of the cell where it's made and affect other nearby cells. If this ApoE4 linked myelination defect appears before clinical diagnosis, that might indicate this is part of the root cause of Alzheimer's disease rather than an exacerbating factor. But as well as being excited by the findings, Karl says there are some things still to be clarified.

00:46 Artemis 1 is go!

NASA’s Artemis 1 mission has successfully reached Earth orbit. After weeks of delays and issues, and a nail biting launch, the rocket marks the first step in a new era of moon exploration, with plans to test a new way to return astronauts to the moon. We caught up with reporter for all-things-space, Alex Witze, for the latest.

12:39 A mechanistic link for an Alzheimer’s gene

Alzheimer’s disease is a form of dementia that affects millions of people every year. Whilst the biggest risk factor of late-onset Alzheimer’s is age, there are a number of genes that have been implicated. How exactly these genes underpin this disease is unclear, but new research may now reveal how one of them does so, by affecting the myelination of neurons. The authors hope this work may help uncover treatments for Alzheimer’s.
