A color-changing helmet could be the key to fighting concussions in football.

Here's a vicious football hit.

Amazingly, the impacts of these two events aren't all that dissimilar.

According to multiple studies, the hardest hits in football can register a whopping g-force of more than 130 (or 130 times the acceleration caused by gravity). For reference, an intense roller coaster registers a g-force of about 5. A severe car crash is somewhere around 120.

Key takeaway: If you ever have a choice between being hit by an NFL linebacker or a pickup, choose the truck.

A g-force of 100 is generally considered plenty of force to sustain a concussion (a traumatic brain injury) though the exact threshold isn't known. But the numbers add up. Over 120 players in the NFL were reported to have sustained a concussion last year, not to mention nearly a quarter million young athletes.

The problem for football players, and team doctors, is that there's no good way to tell just how big a hit was from the sidelines.

Again, we don't know exactly what parameters cause concussions. But we do know there are varying grades of severity. We also know you don't have to be hit in the head to get one.

With so many variables, it can be nearly impossible to know when a football player needs to be evaluated for head injury until they start showing symptoms, like memory loss, nausea, or fatigue.

Sometimes these warning signs show up right away. Sometimes not for days or even weeks. And sometimes, players can hide symptoms in order to stay in the game, putting themselves in even greater danger.

Recently, a confused Wisconsin player wandered into the wrong huddle after a blow to the head. GIF via ESPN.

Thankfully, that could all be about to change.

Scientists from the University of Pennsylvania have developed a color-changing material that could instantly — and visually — indicate severe head trauma.

Penn professor Shu Yang and his team are working to fine-tune a chemical strip made of tiny crystals whose color changes depending on how they're arranged. A physical impact that shifts the arrangement of the crystals can turn the material from its original red to other hues:

Green for big impacts. Purple for even bigger impacts.

When integrated into football helmets, this kind of instant visual cue could be an incredible tool for team doctors and trainers. While it won't by itself diagnose a concussion or other injury, it will help everyone on the field keep a lookout for players who may need to come out of the game for evaluation.

Meanwhile, other companies and researchers are working on helmets that better displace energy from high-impact collisions and tiny remote sensors that transmit measurements of force directly to doctors on the sidelines.

Together, these innovations could make the game we love a lot safer in the coming years, which is great news because it's a fact:

Football's concussion problem is a big one.

Over the past couple of years, concussions in football have been labeled an "epidemic." There have been rule changes at all levels of the sport. New, safer equipment. Even Hollywood movies.

But perhaps most jarring is the slew of young, promising players walking away from the game entirely for fear of long-term brain damage.

Football is a violent sport. It always has been and likely always will be. The players know that. But we owe it to them to make sure they know when they're really in danger. And to make sure they get the treatment they need before serious injuries, like concussions, get worse.

This new helmet technology could go a long way to that end.

Should a man lose his home because the grass in his yard grew higher than 10 inches? The city of Dunedin, Florida seems to think so.

According to the Institute of Justice, which is representing Jim Ficken, he had a very good reason for not mowing his lawn – and tried to rectify the situation as best he could.

In 2014, Jim's mom became ill and he visited her often in South Carolina to help her out. When he was away, his grass grew too long and he was cited by a code office; he cut the grass and wasn't fined.

France has started forcing supermarkets to donate food instead of throwing it away.

But several years later, this one infraction would come back to haunt him after he left to take care of him's mom's affairs after she died. The arrangements he made to have his grass cut fell through (his friend who he asked to help him out passed away unexpectedly) and that set off a chain reaction that may result in him losing his home.

The 69-year-old retiree now faces a $29,833.50 fine plus interest. Watch the video to find out just what Jim is having to deal with.

The world officially loves Michelle Obama.

The former first lady has overtaken the number one spot in a poll of the world's most admired women. Conducted by online research firm YouGov, the study uses international polling tools to survey people in countries around the world about who they most admire.

In the men's category, Bill Gates took the top spot, followed by Barack Obama and Jackie Chan.

In the women's category, Michelle Obama came first, followed by Oprah Winfrey and Angelina Jolie. Obama pushed Jolie out of the number one spot she claimed last year.

Unsurprising, really, because what's not to love about Michelle Obama? She is smart, kind, funny, accomplished, a great dancer, a devoted wife and mother, and an all-around, genuinely good person.

She has remained dignified and strong in the face of rabid masses of so-called Americans who spent eight years and beyond insisting that she's a man disguised as a woman. She's endured non-stop racist memes and terrifying threats to her family. She has received far more than her fair share of cruelty, and always takes the high road. She's the one who coined, "When they go low, we go high," after all.

She came from humble beginnings and remains down to earth despite becoming a familiar face around the world. She's not much older than me, but I still want to be like Michelle Obama when I grow up.

Her memoir, Becoming, may end up being the best-selling memoir of all time, having already sold 10 million copies—a clear sign that people can't get enough Michelle, because there's no such thing as too much Michelle.

Don't like Michelle Obama? Don't care. Those of us who love her will fly our MO flags high and without apology, paying no mind to folks with cold, dead hearts who don't know a gem of a human being when they see one. There is nothing any hater can say or do to make us admire this undeniably admirable woman any less.

When it seems like the world has lost its mind—which is how it feels most days these days—I'm just going to keep coming back to this study as evidence that hope for humanity is not lost.

Here. Enjoy some real-life Michelle on Jimmy Kimmel. (GAH. WHY IS SHE SO CUTE AND AWESOME. I can't even handle it.)

What will future generations never believe that we tolerated in 2019?

Dolphin and orca captivity, for sure. They'll probably shake their heads at how people died because they couldn't afford healthcare. And, they'll be completely mystified at the amount of food some people waste while others go starving.

According to Biological Diversity, "An estimated 40 percent of the food produced in the United States is wasted every year, costing households, businesses and farms about $218 billion annually."

There are so many things wrong with this.

First of all it's a waste of money for the households who throw out good food. Second, it's a waste of all of the resources that went into growing the food, including the animals who gave their lives for the meal. Third, there's something very wrong with throwing out food when one in eight Americans struggle with hunger.

Supermarkets are just as guilty of this unnecessary waste as consumers. About 10% of all food waste are supermarket products thrown out before they've reached their expiration date.

Three years ago, France took big steps to combat food waste by making a law that bans grocery stores from throwing away edible food.According to the new ordinance, stores can be fined for up to $4,500 for each infraction.

Previously, the French threw out 7.1 million tons of food. Sixty-seven percent of which was tossed by consumers, 15% by restaurants, and 11% by grocery stores.

This has created a network of over 5,000 charities that accept the food from supermarkets and donate them to charity. The law also struck down agreements between supermarkets and manufacturers that prohibited the stores from donating food to charities.

"There was one food manufacturer that was not authorized to donate the sandwiches it made for a particular supermarket brand. But now, we get 30,000 sandwiches a month from them — sandwiches that used to be thrown away," Jacques Bailet, head of the French network of food banks known as Banques Alimentaires, told NPR.

It's expected that similar laws may spread through Europe, but people are a lot less confident at it happening in the United States. The USDA believes that the biggest barrier to such a program would be cost to the charities and or supermarkets.

"The logistics of getting safe, wholesome, edible food from anywhere to people that can use it is really difficult," the organization said according to Gizmodo. "If you're having to set up a really expensive system to recover marginal amounts of food, that's not good for anybody."

Plus, the idea may seem a little too "socialist" for the average American's appetite.

"The French version is quite socialist, but I would say in a great way because you're providing a way where they [supermarkets] have to do the beneficial things not only for the environment, but from an ethical standpoint of getting healthy food to those who need it and minimizing some of the harmful greenhouse gas emissions that come when food ends up in a landfill," Jonathan Bloom, the author of American Wasteland, told NPR.

However, just because something may be socialist doesn't mean it's wrong. The greater wrong is the insane waste of money, damage to the environment, and devastation caused by hunger that can easily be avoided.
