I am a contributing editor at Scientific American and write the Brain Waves blog for Psychology Today (you can find those posts here). My work has also appeared in The Atlantic, New York Times, Wall Street Journal, Newsweek, Time, Vogue and many other publications. Earlier in my career, I was on staff at Newsweek, and People, among other places and I’ve included a few of my old favorites from those days.

The Slippery Slope of Dishonesty

A new study proves that once you start lying, your brain stops noticing.

If you say you have never lied, you are almost certainly lying. Only little lies, you say? Well, it’s long been thought that’s where the seeds of dishonesty are usually sown.

With a Little Help From Our Friends

Researchers delving into genetics, social networks and animal behavior are discovering how friendship affects our health and wellbeing–and played a part in our evolutionary story.

When Michigan Governor Rick Snyder testifies today before the Congressional committee investigating Flint’s water crisis, he’s likely to come under heavy criticism. As he should. It took his administration an unconscionably long time to acknowledge the gravity of the…

The Enemy Within

The possibility that autism is caused by a maternal immune system gone awry is no longer a fringe idea – but proposals to identify or fix these glitches are controversial.

Read the original story here.  Judy Van de Water got into autism research precisely because she wasn’t an expert in autism. She is an immunologist, studying the strategies our bodies employ to defend us against pathogens, and the ways those strategies sometimes misbehave or overreact. But about 15 years ago,…

Reconsidering Resolutions

Why I will be keeping it real and saying thank you.

I resolve to change it up this resolution season. Usually, at this time of year, I’m as game as anyone for creating a to-do list of self-improvement. I have always thought of it as an annual refocusing of attention and regularly vowed to exercise more, eat better, work smarter and…
