Inspired by bats, this teen's invention is changing how blind people experience the world.

When he was 12 years old, Alex Deans watched a woman with a visual impairment struggle to cross a busy street.

After a short conversation with her, Alex decided to use his love of science to improve the way people with visual impairments get around in their communities.

He started from scratch, teaching himself how to program and connecting with coders and inventors from around the world in online chat rooms. He thought outside the box when he began to build his new device and found inspiration in nature for tackling the woman's problem in a new way.

It took over five years for Alex to complete his device, which he calls an iAid.

He spent three years working on the prototype and then another three years refining it.

But, boom! He made it happen.

Like the echolocation system bats use, the iAid maps environments using sound waves.

Basically, the iAid is a belt with four sensors, attached to a small joystick.

When used inside , sound waves bounce off objects. The sensors communicate to a joystick, which pivots in the direction the user should go, allowing the person to navigate around obstacles without using a cane.

When used outside , the system uses GPS, Bluetooth, Google Maps, and a cloud service to send information to the user's smartphone, proving once again there really is an app for everything.

The iAid has received lots of positive feedback from testers at the Canadian National Institute for the Blind.

"One of the major things they said was the the device actually improved their confidence in navigation," Alex said in an interview with "Canada AM."

Alex was even named one of Canada's Future Leaders and recently took home the prestigious Weston Youth Innovation Award.

He hopes to use his new-found fame (and $2,000 in prize money) to continue improving the iAid. It's his goal to have the device on the market in two years.

Not bad for someone who's still in Grade 12.

The COVID-19 pandemic has disproportionately affected diverse communities due largely in part to social factors such as inadequate access to housing, income, dietary options, education and employment — all of which have been shown to affect people's physical health.

Recognizing that inequity, Harlem-based chef JJ Johnson sought out to help his community maximize its health during the pandemic — one grain at a time.

Johnson manages FIELDTRIP, a health-focused restaurant that strives to bring people together through the celebration of rice, a grain found in cuisines of countless cultures.

"It was very important for me to show the world that places like Harlem want access to more health-conscious foods," Johnson said. "The people who live in Harlem should have the option to eat fresh, locally farmed and delicious food that other communities have access to."

Lack of education and access to those healthy food options is a primary driver of why 31% of adults in Harlem are struggling with obesity — the highest rate of any neighborhood in New York City and 7% higher than the average adult obesity rate across the five boroughs.

Obesity increases risk for heart disease or diabetes, which in turn leaves Harlem's residents — who are 76% Black or LatinX — at heightened risk for complications with COVID-19.

Empathy. Compassion. Heart-to-heart human connection. These qualities of leadership may not be flashy or loud, but they speak volumes when we see them in action.

A clip of Joe Biden is going viral because it reminds us what that kind of leadership looks like. The video shows a key moment at a memorial service for Chris Hixon, the athletic director at Marjory Stoneman Douglas High School in Parkland, Florida in 2018. Hixon had attempted to disarm the gunman who went on a shooting spree at the school, killing 17 people—including Hixon—and injuring 17 more.

Biden asked who Hixon's parents were as the clip begins, and is directed to his right. Hixon's wife introduces herself, and Biden says, "God love you." As he starts to walk away, a voice off-camera says something and Biden immediately turns around. The voice came from Hixon's son, Corey, and the moments that followed are what have people feeling all their feelings.

Glenda moved to Houston from Ohio just before the pandemic hit. She didn't know that COVID-19-related delays would make it difficult to get her Texas driver's license and apply for unemployment benefits. She quickly found herself in an impossible situation — stranded in a strange place without money for food, gas, or a job to provide what she needed.

Alone, hungry, and scared, Glenda dialed 2-1-1 for help. The person on the other end of the line directed her to the Houston-based nonprofit Bread of Life, founded by St. John's United Methodist pastors Rudy and Juanita Rasmus.

For nearly 30 years, Bread of Life has been at the forefront of HIV/AIDS prevention, eliminating food insecurity, providing permanent housing to formerly homeless individuals and disaster relief.

Glenda sat in her car for 20 minutes outside of the building, trying to muster up the courage to get out and ask for help. She'd never been in this situation before, and she was terrified.

When she finally got out, she encountered Eva Thibaudeau, who happened to be walking down the street at the exact same time. Thibaudeau is the CEO of Temenos CDC, a nonprofit multi-unit housing development also founded by the Rasmuses, with a mission to serve Midtown Houston's homeless population.

Back in 2017, when white supremacist Richard Spencer was socked in the face by someone wearing all black at Trump's inauguration, it launched an online debate, "Is it OK to punch a Nazi?"

The essential nature of the debate was whether it was acceptable for people to act violently towards someone with repugnant reviews, even if they were being peaceful. Some suggested people should confront them peacefully by engaging in a debate or at least make them feel uncomfortable being Nazi in public.

The English language is constantly evolving, and the faster the world changes, the faster our vocabulary changes. Some of us grew up in an age when a "wireless router" would have been assumed to be a power tool, not a way to get your laptop (which wasn't a thing when I was a kid) connected to the internet (which also wasn't a thing when I was a kid, at least not in people's homes).

It's interesting to step back and look at how much has changed just in our own lifetimes, which is why Merriam-Webster's Time Traveler tool is so fun to play with. All you do is choose a year, and it tells you what words first appeared in print that year.

For my birth year, the words "adult-onset diabetes," "playdate," and "ATM" showed up in print for the first time, and yes, that makes me feel ridiculously old.

It's also fun to plug in the years of different people's births to see how their generational differences might impact their perspectives. For example, let's take the birth years of the oldest and youngest members of Congress:
