“People wrap themselves in their beliefs. And they do it in such a way that you can't set them free. Not even the truth will set them free.”

“With a hundred and seventy-eight machines to sequence the precise order of the billions of chemicals within a molecule of DNA, B.G.I. produces at least a quarter of the world's genomic data - more than Harvard University, the National Institutes of Health, or any other scientific institution.”

“There has never been a verified scientific report that chelation therapy, a gluten-free diet, or anything else can cure autism.”

“The most blatant forms of denialism are rarely malevolent; they combine decency, a fear of change, and the misguided desire to do good - for our health, our families, and the world. That is why so many physicians dismiss the idea that a patient's race can, and often should, be used as a tool for better diagnoses and treatment.”

“Consumers deserve the right to know what's in their food - and obviously, most people want that choice. It's hard to see how more knowledge about the products we eat every day can hurt us.”

“All the food we eat - every grain of rice and kernel of corn - has been genetically modified. None of it was here before mankind learned to cultivate crops. The question isn't whether our food has been modified, but how.”

“There is a major problem with reliance on placebos, like most vitamins and antioxidants. Everyone gets upset about Big Science, Big Pharma, but they love Big Placebo.”

“When people say they prefer organic food, what they often seem to mean is they don't want their food tainted with pesticides and their meat shot full of hormones or antibiotics. Many object to the way a few companies - Monsanto is the most famous of them - control so many of the seeds we grow.”

“Concepts of memory tend to reflect the technology of the times. Plato and Aristotle saw memories as thoughts inscribed on wax tablets that could be erased easily and used again. These days, we tend to think of memory as a camera or a video recorder, filming, storing, and recycling the vast troves of data we accumulate throughout our lives. In practice, though, every memory we retain depends upon a chain of chemical interactions that connect millions of neurons to one another. Those neurons never touch; instead, they communicate through tiny gaps, or synapses, that surround each of them. Every neuron has branching filaments, called dendrites, that receive chemical signals from other nerve cells and send the information across the synapse to the body of the next cell. The typical human brain has trillions of these connections. When we learn something, chemicals in the brain strengthen the synapses that connect neurons. Long-term memories, built from new proteins, change those synaptic networks constantly; inevitably, some grow weaker and others, as they absorb new information, grow more powerful.”
