Herpes simplex virus type 1 (HSV-1) is a common human virus, you get a cold sore near the mouth, but a study of the full genetic code of HSV-1 shows a dramatic confirmation of the "out-of-Africa" pattern of human migration., according to their paper.

Geneticists explore how organisms are related by studying changes in the sequence of bases, or "letters" on their genes. From knowledge of how quickly a particular genome changes, they can construct a "family tree" that shows when particular variants had their last common ancestor.

Studies of human genomes have shown that our ancestors emerged from Africa roughly 150,000 to 200,000 years ago, and then spread eastward toward Asia, and westward toward Europe.

In the early parts of Dan Brown's "The DaVinci Code" he spends a great deal of time outlining how both art history (no, really) and his particular brand of religious revisionism are legitimate ... but repressed by Big Religion.

In science, we see that all of the time; X says he can invent perpetual motion or has overturned some aspect of medicine or biology and "dogma" keeps it hidden. It's the myth of the oppressed underdog. Americans love it, it's good reading, David vs. Goliath stuff. It is the story of how America came to be.

Marijuana use continues to be on the upswing in the United States. A public relations campaign claiming health benefits while ignoring health risks have led to diminishing public disapproval and more lenient legislation.

People who disapprove of a particular drug are unlikely to use it, but what about the gateway affect? Does the use of one drug affects people's attitudes toward using other drugs? Do personality traits matter?

High school seniors who frown upon the use of drugs are most likely to be female, nonsmokers or hold strong religious beliefs, according to a paper by Joseph Palamar of New York University. Palamar that examines how teenagers' attitudes toward marijuana influenced their thoughts on the further use of other illicit drugs. 

The early days of Ashkenazi Jews – that is, Jews with more recent ancestry in central and Eastern Europe – are a hot debate topic. It is believed that their ancestors migrated into Europe from Judea in the first century A.D., after the destruction of the Second Temple by the Romans, and that led to some intermarriage with Europeans later on.  

Others have argued that they have a mainly European ancestry, and arose by conversion to Judaism of indigenous Europeans, especially in Italy. While still others have even argued that they were largely assimilated in the North Caucasus during the time of the Khazar Empire, the Turkic people in the Western steppe whose rulers turned to Judaism around of the tenth century AD.

Transgendered androphilic males may have been accepted in ancient hunter-gatherer cultures because they were an extra set of hands to support their families, according to a new article in Human Nature.

Hyperlink films, which use cinematic devices such as flashbacks, scenes out of chronological order, split screens and voiceovers to create an interacting network of storylines and characters across space and time, mirror contemporary globalized communities, it is said.

However, films in this genre like "Memento", "Love Actually" and "Crash" are not as new and innovative as believed - they still conform to conventional cinematic and social patterns, say scholars after an examination of twelve hyperlink films, ten female interest conventional films and examples from the real world and classical fiction.  

A bone fragment from a French archaeological site has turned out to be a part of an early specialized bone tool used by a Neanderthal before the first modern humans appeared in Europe.

Trailer park residents are one of the few demographics it's still okay to stereotype but, as is usually the case, low-income trailer park residents form distinct groups with different visions of morality, according to a new paper. In other words, they are no more easy to quantify than anyone else.

Though some Europeans were still hunter-gatherers in 4,600 BC, there was interaction between the hunter-gatherer and farming communities and a 'sharing' of animals and knowledge  which led to acquisition of domesticated pigs from nearby farmers, according to new evidence.
