Laterality is the preference of human beings for one side of our bodies; being left-handed or right-handed, for example, or having a preference for using one eye or ear or the other.

In the view of primatologist Eder Domínguez-Ballesteros, "lateralized behavior in humans may in some way have been reflected in their technological products, in particular, in the things they made. Besides, flint knapping -inherent in our genus since the first stages in its evolution- is an excellent source of information for studying lateralization in humans."

Our linguistic and legal obsession with “insult” and “offense” is nothing new. In 1832, Sydney resident William McLoughlin was given 50 lashes for using the word “damned” against his master.

But what does McLoughlin’s case tell us about today?

Welsh Rabbit and lashes from pretty fellows

The word insult can be traced to the Latin insultāre “to leap upon” or “assail”. It possibly entered English via a Middle French word insulter, meaning “to insult, crow, vaunt, or triumph over; to wrong, reproach, affront”.

An analysis of about 1,300 peer-reviewed research articles found that few studies included men and women equally, less than one-third performed data analysis by sex, and there was wide variation in inclusion and matching of the sexes among the specialties and the journals reviewed, according to a paper JAMA Surgery.

Males and females can have different postoperative outcomes, complication rates, and readmission rates, so it is important to know if sex bias is pervasive in surgery. Adequately controlling for sex as a variable with inclusion, data reporting, and data analysis is important because data derived from clinical research are the foundation for evidence-based medicine.

Does free health care or terrific medical treatment make citizens unwilling to change their lifestyle? There is a valid argument it is true. HIV has plummeted among every demographic except gay men, who have been found to engage in risky behavior because treatment is now so good. And free health care may be causing Canadians to not engage in personal responsibility in their lifestyles. 

According to a new study in PLOS Medicine, poor diet, smoking, and unwillingness to exercise contribute to about 50 percent of deaths in Canada.

Archaeological sites speak about the everyday lives of people in other times. Yet knowing how to interpret this reality does not tend to be straightforward. We know that Palaeolithic societies lived on hunting and gathering, but the bones found in prehistoric settlements are not always the food leftovers of the societies that lived in them. Or they are not exclusively that.

Should we be warning consumers about over-consumption of meat as well as sugar?

That's the question being raised by a team of researchers from the University of Adelaide, who say meat in the modern diet offers surplus energy, and is contributing to the prevalence of global obesity.

There is just one problem. The only data available is types of food, they have no idea whether the obese people ate any meat. Or any sugar. If just the availability of meat makes people obese, they have overturned everything science knows about cellular respiration.

Think tanks are designed to help policy makers shape decisions by giving them evidence-based information in an apolitical format.

Who doesn't claim to be doing that? Though Sierra Club and Environmental Defense Fund were both inspired by rabid eugenics proponents who simply reframed their beliefs about the poor being vermin into the "population control" rhetoric after World War II, they still claim they are more consumer advocacy oriented than corporations that actually help people. And government-controlled panels like the International Agency for Research on Cancer agree, an expert on a pesticide who works for the private sector can't be on their pesticide working group but an anti-pesticide consultant for EDF can be.

The U.S. Centers for Disease Control and Prevention have recently become concerned about e-cigarette use yet scarcely mention that cigarette uptake has plummeted.

Cigarettes are the killer, not nicotine, but nicotine is what historically turned smoking into what the American Council on Science and Health (ACSH) deems a pediatric disease. Like caffeine, nicotine is addictive. If you smoked caffeine in a cigarette, it would be incredibly toxic whereas nicotine itself is relatively harmless. And because the CDC has overreacted to e-cigarettes, they become a cool rebellious thing for teems, just like cigarettes once were.

The woman was laid on a bed of specially selected materials, including gazelle horn cores, fragments of chalk, fresh clay, limestone blocks and sediment. Tortoise shells were placed under and around her body, 86 in total. Sea shells, an eagle's wing, a leopard's pelvis, a forearm of a wild boar and even a human foot were placed on the body of the mysterious 1.5 meter-tall woman. Atop her body, a large stone was laid to seal the burial space.

In the modern schism between religion and science promoted by militants, it may not seem like theology is a friend to ecology. But, like in all other areas of science, that is just modern spin created by people who need to promote that culture war for their own ends. Including in environmentalism, where religion is portrayed as a conservative trait.
