This Knee Crack is The Worst Sound Ever (And It’s Good For You) 

Knees sound terrifying when amplified, FYI. A team of researchers studying knee grinding sounds may do great medical good though, if their sound-based research and technology ends up helping people with a cute knee injuries.

It’s still probably the worst sound ever.

Kim Horcher and Alan Kistler (Author, Pop Culture Historian) discuss!

Diabetes Complication and Pathophysiology 

The physiology of insulin, pathophysiology of type II diabetes and its complications.

“Glucose metabolism is normally regulated by a feedback loop including islet β cells and insulin-sensitive tissues, in which tissue sensitivity to insulin affects magnitude of β-cell response. If insulin resistance is present, β cells maintain normal glucose tolerance by increasing insulin output. Only when β cells cannot release sufficient insulin in the presence of insulin resistance do glucose concentrations rise.” (Kahn, Cooper & Prato 2014).

The physics of the sneeze 

Sneezes play an important part in the spread of infections, but we don’t know a huge amount about how they work. Lydia Bourouiba’s lab at MIT is trying to change that, using slow motion footage and other measurements to study the fluid dynamics of sneezing.
