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

Here's a vicious football hit.

Now here's a truck slamming into a wall at 80 mph.

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.

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.

On an old episode of "The Oprah Winfrey Show" in July 1992, Oprah put her audience through a social experiment that puts racism in a new light. Despite being nearly two decades old, it's as relevant today as ever.

She split the audience members into two groups based on their eye color. Those with brown eyes were given preferential treatment by getting to cut the line and given refreshments while they waited to be seated. Those with blue eyes were made to put on a green collar and wait in a crowd for two hours.

Staff were instructed to be extra polite to brown-eyed people and to discriminate against blue-eyed people. Her guest for that day's show was diversity expert Jane Elliott, who helped set up the experiment and played along, explaining that brown-eyed people were smarter than blue-eyed people.

Watch the video to see how this experiment plays out.

Cadbury has removed the words from its Dairy Milk chocolate bars in the U.K. to draw attention to a serious issue, senior loneliness.

On September 4, Cadbury released the limited-edition candy bars in supermarkets and for every one sold, the candy giant will donate 30p (37 cents) to Age UK, an organization dedicated to improving the quality of life for the elderly.

Cadbury was prompted to help the organization after it was revealed that 225,000 elderly people in the UK often go an entire week without speaking to another person.

Well Being

Young people today are facing what seems to be greater exposure to complex issues like mental health, bullying, and youth violence. As a result, teachers are required to be well-versed in far more than school curriculum to ensure students are prepared to face the world inside and outside of the classroom. Acting as more than teachers, but also mentors, counselors, and cheerleaders, they must be equipped with practical and relevant resources to help their students navigate some of the more complicated social issues – though access to such tools isn't always guaranteed.

Take Dr. Jackie Sanderlin, for example, who's worked in the education system for over 25 years, and as a teacher for seven. Entering the profession, she didn't anticipate how much influence a student's home life could affect her classroom, including "students who lived in foster homes" and "lacked parental support."

Valerie Anglemyer, a middle school teacher with more than 13 years of experience, says it can be difficult to create engaging course work that's applicable to the challenges students face. "I think that sometimes, teachers don't know where to begin. Teachers are always looking for ways to make learning in their classrooms more relevant."

So what resources do teachers turn to in an increasingly fractured world? "Joining a professional learning network that supports and challenges thinking is one of the most impactful things that a teacher can do to support their own learning," Anglemyer says.

A new program for teachers that offers this network along with other resources is the WE Teachers Program, an initiative developed by Walgreens in partnership with ME to WE and Mental Health America. WE Teachers provides tools and resources, at no cost to teachers, looking for guidance around the social issues related to poverty, youth violence, mental health, bullying, and diversity and inclusion. Through online modules and trainings as well as a digital community, these resources help them address the critical issues their students face.

Jessica Mauritzen, a high school Spanish teacher, credits a network of support for providing her with new opportunities to enrich the learning experience for her students. "This past year was a year of awakening for me and through support… I realized that I was able to teach in a way that built up our community, our school, and our students, and supported them to become young leaders," she says.

With the new WE Teachers program, teachers can learn to identify the tough issues affecting their students, secure the tools needed to address them in a supportive manner, and help students become more socially-conscious, compassionate, and engaged citizens.

It's a potentially life-saving experience for students, and in turn, "a great gift for teachers," says Dr. Sanderlin.

"I wish I had the WE Teachers program when I was a teacher because it provides the online training and resources teachers need to begin to grapple with these critical social issues that plague our students every day," she adds.

In addition to the WE Teachers curriculum, the program features a WE Teachers Award to honor educators who go above and beyond in their classrooms. At least 500 teachers will be recognized and each will receive a $500 Walgreens gift card, which is the average amount teachers spend out-of-pocket on supplies annually. Teachers can be nominated or apply themselves.

One of the major differences between women and men is that women are often judged based on their looks rather than their character or abilities.

"Men as well as women tend to establish the worth of individual women primarily by the way their body looks, research shows. We do not do this when we evaluate men," Naomi Ellemers Ph.D. wrote in Psychology Today.

Dr. Ellers believes that this tendency to judge a woman solely on her looks causes them to be seen as an object rather than a person.
