“Heart Strings”

Thanks to the wonders of magnetic resonance imaging (MRI), amazing images of “heart strings” — the muscle fiber orientation of the left ventricle of the heart – have been obtained. According to the University of Oxford:

The image was produced using a branch of magnetic resonance imaging (MRI) called diffusion tensor imaging (DTI). The technique tracks the diffusion of water throughout the myocardium (the heart’s muscular wall comprising interconnected sheets of muscle cells called myocytes). Due to the way the myocytes are organized, the movement of water is restricted, so tracking the location of water molecules can reveal valuable information about the structure of the heart in a non-invasive way.

Nice.

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
