In this week's episode of the Beta Sandwich Science Podcast Karolina and the team discuss Magnesium and its role in your body. Over half of Americans have low Mg levels (Hypomagnesemia,) and this can lead to hypocalcemia, low serum potassium levels (hypokalemia), retention of sodium, low circulating levels of parathyroid hormone (PTH), neurological and muscular symptoms (tremor, fasciculations, muscle spasms, tetany), loss of appetite, nausea, vomiting, personality changes (source: Wikipedia). In 'Science Blast' we discuss: How a very high protein diet may affect kidney health, and how humans may be able to smell when someone is sick. In 'Making the Grad' Del talks about life is like around the world for young Ph.Ds. who elect to remain in academia.
