Benefits of Sleeping for Memorization

Researchers at a City College of New York sleep lab have found that a 45-minute daytime nap can help a person remember facts.
The brain files newly acquired memories into two main compartments. Those relating to skills go into our procedural memory compartment while those concerning facts, such as the stuff we learn from books, documentaries, and from interacting with other people, end up in our declarative memory compartment.
The experiment, led by Dr. Matthew Tucker, a Harvard Medical School fellow, tested 33 people on their declarative memory capability to remember unrelated word pairs, mazes, and complex line drawings.
The volunteers who took a 45-minute nap at the start of the 3-hour break between memorizing and testing performed much better than those who stayed in the lab and watched TV.



p.s. I am so sleepy Zzz -_-

Asian Hair

Hairdressers know that East Asians have the thickest hair in the world, and now scientists know why.
Geneticists in Thailand, Indonesia, and Japan found Asian hair 30% thicker than African and 50% thicker than European. They then turned to the HapMap Project, where scientists throughout the world compared gene variations among Nigerians, Europeans, Chinese, and Japanese and discovered that 88% of the Asians had a variation or mutation in a gene named EDAR, which is involved in the creation of hair follicles. The other two races didn't have the variation nor such thick strands of hair.
