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 global eradication of smallpox in 1980 is one of international public health's greatest successes. But in 1966, seven years after the World Health Organization announced a plan to rid the world of the disease, smallpox was still widespread. The culprits? A lack of funds, personnel and vaccine supply.

Meanwhile, outbreaks across South America, Africa, and Asia continued, as the highly contagious virus continued to kill three out of every 10 people who caught it, while leaving many survivors disfigured. It took a renewed commitment of resources from wealthy nations to fulfill the promise made in 1959.

Forty-one years later, although we face a different virus, the potential for vast destruction is just as great, and the challenges of funding, personnel and supply are still with us, along with last-mile distribution. Today, while 30% of the U.S. population is fully vaccinated, with numbers rising every day, there is an overwhelming gap between wealthy countries and the rest of the world. It's becoming evident that the impact on the countries getting left behind will eventually boomerang back to affect us all.

The international nonprofit CARE recently released a policy paper that lays out the case for U.S. investment in a worldwide vaccination campaign. Founded 75 years ago, CARE works in over 100 countries and reaches more than 90 million people around the world through multiple humanitarian aid programs. Of note is the organization's worldwide reputation for its unshakeable commitment to the dignity of people; they're known for working hand-in-hand with communities and hold themselves to a high standard of accountability.

"As we enter into our second year of living with COVID-19, it has become painfully clear that the safety of any person depends on the global community's ability to protect every person," says Michelle Nunn, CARE USA's president and CEO. "While wealthy nations have begun inoculating their populations, new devastatingly lethal variants of the virus continue to emerge in countries like India, South Africa and Brazil. If vaccinations don't effectively reach lower-income countries now, the long-term impact of COVID-19 will be catastrophic."

As millions of Americans have raced to receive the COVID-19 vaccine, millions of others have held back. Vaccine hesitancy is nothing new, of course, especially with new vaccines, but the information people use to weigh their decisions matters greatly. When choices based on flat-out wrong information can literally kill people, it's vital that we fight disinformation every which way we can.

Researchers at the Center for Countering Digital Hate, a not-for-profit non-governmental organization dedicated to disrupting online hate and misinformation, and the group Anti-Vax Watch performed an analysis of social media posts that included false claims about the COVID-19 vaccines between February 1 and March 16, 2021. Of the disinformation content posted or shared more than 800,000 times, nearly two-thirds could be traced back to just 12 individuals. On Facebook alone, 73% of the false vaccine claims originated from those 12 people.

Dubbed the "Disinformation Dozen," these 12 anti-vaxxers have an outsized influence on social media. According to the CCDH, anti-vaccine accounts have a reach of more than 59 million people. And most of them have been spreading disinformation with impunity.
