Sixteen Years After Scientists Warned About Endocrine Disruptors in Plastic Bottles, What Does the Evidence Actually Say?
In 2010, a physician named Leonard Sax published a two-page commentary in a peer-reviewed environmental health journal, and it has been quietly fueling water-bottle anxiety ever since. The paper, "Polyethylene Terephthalate May Yield Endocrine Disruptors," didn't report an experiment. Sax ran no lab work of his own. What he did was lay out a hypothesis: that PET — the clear, lightweight plastic used in most disposable water bottles — might leach chemicals capable of interfering with the body's hormones. He pointed to a handful of early studies on phthalates and antimony, cited a striking 2009 finding on mud snails, and closed with a sentence that got left behind as the idea spread: "More research is needed."

When Development Ends, Does the Window Close With It?
There is a quiet assumption buried inside how most of us think about the brain: that whatever happens during development becomes the brain's permanent architecture. A childhood of altered wiring hardens into an adult structure that can be managed or medicated around, but not fundamentally revisited. The early years are when the building gets built; afterward, you live in the house.

Can You Prevent Your Skin From Ageing?
Question : Elaine, do you dread ageing and worry about it? Are you feeling unhappy about any creases or lines you might see on your face? Can we stop our skin from ageing? I am constantly worrying about my skin changing, but don’t want to be paranoid out it. How can I accept it?

Falling Apart
Introduction I often write things about mortality and my eventual demise, although this is not a downer piece. I have a fear of repeating myself and found this previous piece on Vocal, which was rejigged from a Seven Days In post from 2017:

Meditation Has Been Studied for Decades. What Has Science Actually Found?
There is something strange about the position meditation now occupies. Few practices have accumulated so much peer-reviewed research and so large a halo of claims at the same time. Depending on which corner of the internet you land in, meditation may supposedly ease anxiety, prevent depression, sharpen attention, deepen sleep, dial down chronic pain, lower blood pressure, quiet inflammation, strengthen immunity, rewire the brain, and even slow the biological clock inside your cells.

A Calorie Is a Measurement. A Molecule Is a Message.
A calorie is a unit of energy. Nutrition labels don't arrive at that number by incinerating food in a lab; modern food energy values are typically calculated using metabolizable-energy systems, such as Atwater factors, that estimate how much of a nutrient's raw energy content the body can actually extract and use. Either way, the number is a quantitative measure of available fuel. Glucose and fructose are even the same chemical formula, C₆H₁₂O₆, just arranged differently, and both supply roughly the same number of calories per gram. If you replaced one with the other in a recipe, the calorie count on the label wouldn't change by a single digit.

Whose Gut Became "Normal"?
Imagine a team of scientists sets out to define the healthy human gut. They recruit thousands of volunteers, sequence trillions of microbes, and build an elegant statistical portrait of what a "normal" microbiome looks like. There's just one detail worth noticing: nearly everyone in the study lives in a large city, eats food that arrived in a package, has taken antibiotics more than once, drinks treated tap water, rarely touches soil, and has not hosted an intestinal parasite in their life.
