The majority of "fused" people, those who view themselves as completely immersed in a group, are willing to commit extreme acts for the good of their compatriots, says research soon to appear in Psychological Science.
In the study, the researchers recruited 506 college students at the Universidad Nacional de Educacion a Distancia in Spain. Based on the students' answers in online questionnaires, the researchers identified 38 percent of the participants as "fused" as compared to "non-fused," with Spain. They then measured their self-sacrificial behaviors.
If you want to really get back to nature, it still involves meat. A team of researchers has discovered evidence that human ancestors were using stone tools and consuming the meat and marrow of large mammals 1 million years earlier than previously documented.
While working in the Afar region of Ethiopia, the Dikika Research Project (DRP) found bones bearing unambiguous evidence of stone tool use - cut marks made while carving meat off the bone and percussion marks created while breaking the bones open to extract marrow. The bones date to roughly 3.4 million years ago and provide the first evidence that Lucy's species, Australopithecus afarensis, used stone tools and consumed meat.
One solution to the heart risk caused by obesity, although an obtuse one, is to add things to the junk food industry instead of taking away some junk food.
Researchers at Imperial College London writing in the American Journal of Cardiology suggest fast food vendors provide statin drugs free of charge. Statins reduce the amount of unhealthy LDL cholesterol in the blood, and trial data has shown them to be highly effective at lowering a person's heart attack risk.
In the study, Dr. Darrel Francis and colleagues calculate that the reduction in cardiovascular risk offered by a statin is enough to offset the increase in heart attack risk from eating a cheeseburger and a milkshake.
