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.

Rice farming is a far older practice than we knew. The oldest evidence of domesticated rice in China has now been pushed back to 9,000 years ago, thanks to a team of archaeologists.

Euthanasia with the use of physicians is supported by a majority of California and Hawaii residents, regardless of their ethnicity - as reliable as an Internet survey can be, that is.

Older people were more likely than younger people to feel it is acceptable for physicians, who obey the Hippocratic oath, to prescribe life-ending drugs for terminally ill patients who request them. Even among people who consider themselves spiritual or religious, about 52 percent supported the practice.

Heralded on the cover of Time magazine in 2000 as a genetically modified (GMO) crop with the potential to save millions of lives in the Third World, Golden Rice is still years - and millions of dollars in anti-science activism - away from field introduction.  Vitamin A deficiencies leave millions at high risk for infection, diseases and other maladies, such as blindness, and Golden Rice produces  the micronutrient beta carotene, so it is basically fortified, but using a natural process that increases Vitamin A rather than an additive.

Infant formula was the great liberator for working moms who wanted to have careers but in the last decade there has been a backlash against it, often adopting the veil of scientific legitimacy.
