A Bizarre Bazaar of Food Facts

Food is both mundane and magical, ephemeral and essential – the ultimate cultural touchstone. Our religions proscribe taboo foods, oblige sacred meals and employ food as a conduit for sacred power. Our myths abound with divine edibles that grant gods immortality, while our folktales counsel against feasting in fairyland lest we trap ourselves forever.

But for all the reverence we pay them, many comestibles arose from humble, bizarre or even disgusting sources, while what we choose, or are compelled, to eat is driven by everything from necessity to neurosis. For better or worse, food scientists, molecular gastronomists and, yes, marketing  firms channel these impulses in profitable (if not always healthy directions). The results are, shall we say, appetizingly bizarre …

The Scientist and the Sea Serpent

Most seafaring cultures have sea monster myths or folktales. They are preserved in manuscripts, in the margins of old maps, on the walls of Hindu temples and in the rock carvings of American Indians. Tales tell of monstrous sea gods and their fearsome servants as well as other assorted briny beasts. But is there a drop of truth to any of these tall tales? And how might we find out? Join me as I explore…

10 History-making Hispanic Researchers

Far too many scientists who made major contributions to knowledge and human health go unremarked, forgotten save for the occasional postage stamp or Google doodle. So when I was offered the chance to write about a few of the many outstanding scientists who came from Spanish-speaking lands, cultures and ancestors, I was understandably excited…and a little nervous. On the one hand, combining such a varied assemblage of people under one term – especially the political term Hispanic – wasn’t ideal. On the other hand, it gave me the chance to explore, and raise awareness of, a remarkably diverse array of persons, backgrounds and accomplishments. I hope you’ll find their stories as inspiring as I did.

The Causation-Correlation Conflation

Not equal signThe question of cause  has haunted science and philosophy from their earliest days, in part because humans are wired for pattern-matching and confirmation bias. For all our supposed rationality, we confuse coincidence with correlation and correlation with causality.

Consequently, scientists must carefully design and control their experiments to remove bias, circular reasoning, self-fulfilling prophecies and hidden variables. They must respect the requirements and limitations of their methods, draw from representative samples and not overstate their results. Sometimes, however, that’s easier said than done. Read on to hear about…

Questioning the Decline of Human Intelligence

Science still struggles to define, measure or understand intelligence, let alone definitively nail down its genetic components. Yet one Stanford geneticist argues that civilization was a bad move, and that human intelligence has gradually ratcheted down  since leaving its hunter-gatherer days behind.

Is the Peter Principle killing our intellect, or is Crabtree’s model another unripe hypothesis that received too much media attention? Read on to find out.
