Listening is a more natural way of learning, when compared to reading. Written
language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through
audio (audio article). You could even learn subconsciously by playing the audio
while you are sleeping! If you are planning to listen a lot, you could try using
a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Xanthurenic acid, or xanthurenate, is a chemical shown to induce gametogenesis of Plasmodium falciparum, the parasite that causes malaria. It is found in the gut of the Anopheles mosquito.
Xanthurenic acid is a metabolic intermediate that accumulates and is excreted by pyridoxine (vitamin B6) deficient animals after the ingestion of tryptophan.Xanthurenic acid is suspected to be an endogenous agonist for Group II metabotropic glutamate receptors in humans. It is also known to be a potent VGLUT inhibitor, thereby preventing the movement of glutamate from the cytoplasm into synaptic vesicles, an action that it mediates via competitive blockade of vesicular glutamate transporters (Ki = 0.19 mM).
In 2015 researchers reported a marked reduction of xanthurenic acid levels in the serum of patients with schizophrenia, describing this phenomenon as a potential trait marker for schizophrenia.
