Using chest pain characteristics (CPCs) specific to women in the early diagnosis of acute myocardial infarction (AMI, heart attack) in the emergency department does not seem to be supported by the findings of a new study.

While about 90 percent of patients with AMI present with chest pain or discomfort, some patients present without typical chest pain. Sex-specific differences in symptom presentation among women have received increasing attention. But it remains unclear whether identifying sex-specific CPCs is possible to help physicians differentiate women with AMI from women with other causes of chest pain, the authors write in the study background.

Retroviruses are important pathogens capable of crossing species barriers to infect new hosts, but knowledge of their evolutionary history is limited. By mapping endogenous retroviruses (ERVs), retroviruses whose genes have become part of the host organism's genome, researchers at Uppsala University, Sweden, can now provide unique insights into the evolutionary relationships of retroviruses and their host species.

Archaeologists working in Nepal have uncovered evidence of a structure at the birthplace of the Buddha dating to the sixth century B.C., the first archaeological material linking the life of the Buddha and the movement he founded to a specific century.

The Maya Devi Temple at Lumbini, Nepal, has long been considered the birthplace of the Buddha and now excavations have uncovered the remains of a previously unknown sixth-century B.C. timber structure under a series of brick temples. Laid out on the same design as those above it, the timber structure contains an open space in the center that links to the nativity story of the Buddha himself. 

Playing violent video games not only increases aggression, it also leads to less self-control and more cheating, according to  a paper in Social Psychological and Personality Science.

The psychologists found that teens who played violent video games ate more chocolate and were more likely to steal raffle tickets in a lab experiment than were teens who played nonviolent games. The effects were strongest in those who scored high on a measure of moral disengagement – the ability to convince yourself that ethical standards don't apply to you in a particular situation. 

Global warming was set in motion around 1600 AD, it seems. 

Because carbon dioxide emissions persist for a long time, even a sudden halt today means the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years, according to a numerical model which suggests that it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe.

Awe-inspiring moments, like the sight of the Grand Canyon or the Aurora Borealis, might increase our tendency to believe in God and the supernatural, according to a new paper in Psychological Science which suggests that awe-inspiring sights increase our motivation to make sense of the world around us. Learning geology may be too hard to it's easier to default to aliens or religion.
