Men and women are different, but not because of what's inside our brains. A new study explains why.

Have you ever heard that women are "hardwired" to have better memories? Or that men are "naturally" better at navigating?

Sure, they're just stereotypes, but they're coming from somewhere. And for a long time we've been led to believe that men's and women's brains are fundamentally different, so why couldn't blanket statements like these hold some truth?

Neuroscientist Gina Rippon, a professor at Aston University and noted speaker on the subject of sex differences, offered a different idea in 2014. She believes these patterns are acquired through environmental factors — a woman could become great at multitasking because society expects her to be better at it, for example — not because of any innate wiring in her brain.

Now, a new study says she might be right.

A team led by researchers at Tel Aviv University in Israel recently concluded that there is no consistent difference between male and female brains.

The team, led by behavioral neuroscientist Daphna Joel, analyzed the MRI scans of 1,400 individuals, mapping things like gray matter (gooey stuff that handles sensation, emotion ... pretty much everything), white matter (the gooey stuff that carries messages between areas of gray matter), and a host of personality traits along the way.

What did they find? That it's pretty dang rare for a given brain to demonstrate only male or female characteristics.

So next time someone says to you, "Women's brains do this" or "Men's brains behave like this," feel free to call B.S.

The plain truth is that our brains flat out can't be separated into two distinct gender categories.

Our brains, the researchers say, are more like "mosaics" — wonderful mixtures of the traits we usually associate with men or women.

That's not to say the study found no differences between the brains of men and women, but rather that a brain consisting of almost all male or female features was pretty uncommon, and that it'd be really tough to tell if a person were biologically male or female just by looking at their brain.

It's a great reminder that gendering activities and behaviors is a bunch of bunk. Video games aren't just for boys. Shopping isn't just for girls.

If you're not looking at an individual person holistically for the things that make them them, you're doing it wrong.

Better yet, The Washington Post writes that these findings are "a step towards validating the experiences of those who live outside the gender binary."

It's just more evidence to support the idea that the biological "parts" you're born with don't really tell us much about who you are.

Turns out that what's inside is much more fluid and malleable than we ever imagined.

In America, one dumb mistake can hang over your head forever.

Nearly 30% of the American adult population — about 70 million people — have at least one criminal conviction that can prevent them from being treated equally when it comes to everything from job and housing opportunities to child custody.

Twenty million of these Americans have felony convictions that can destroy their chances of making a comfortable living and prevents them from voting out the lawmakers who imprisoned them.

Many of these convictions are drug-related and stem from the War on Drugs that began in the U.S. '80s. This war has unfairly targeted the minority community, especially African-Americans.

Climate change is happening because the earth is warming at an accelerated rate, a significant portion of that acceleration is due to human activity, and not taking measures to mitigate it will have disastrous consequences for life as we know it.

In other words: Earth is heating up, it's kinda our fault, and if we don't fix it, we're screwed.

This is the consensus of the vast majority of the world's scientists who study such things for a living. Case closed. End of story.

How do we know this to be true? Because pretty much every reputable scientific organization on the planet has examined and endorsed these conclusions. Thousands of climate studies have been done, and multiple peer-reviewed studies have been done on those studies, showing that somewhere between 84 and 97 percent of active climate science experts support these conclusions. In fact, the majority of those studies put the consensus well above 90%.

Two years ago, a tweet featuring the invoice for a fixed boiler went viral because the customer, a 91-year-old woman with leukemia, received the services for free.

"No charge for this lady under any circumstances," the invoice read. "We will be available 24 hours to help her and keep her as comfortable as possible."

The repair was done by James Anderson, 52, a father-of-five from Burnley, England. "James is an absolute star, it was overwhelming to see that it cost nothing," the woman's daughter told CNN.

I live in a family with various food intolerances. Thankfully, none of them are super serious, but we are familiar with the challenges of finding alternatives to certain foods, constantly checking labels, and asking restaurants about their ingredients.

In our family, if someone accidentally eats something they shouldn't, it's mainly a bit of inconvenient discomfort. For those with truly life-threatening food allergies, the stakes are much higher.

I can't imagine the ongoing stress of deadly allergy, especially for parents trying to keep their little ones safe.
