Montreal-based 9th-grader Aviana Machnes didn’t only come up with an award-winning science fair idea, she created a device that could save the lives of dementia patients. It all started with a pot left out on the stove. 

As reported by Global News, Machnes’ grandmother, who has early-onset dementia, had forgotten to take a pot off the hot stove, subsequently leaving it there overnight. Finding no solutions to this problem, Machnes decided to tackle it herself. 

Using current sensors and motion detectors, Machnes created a device dubbed the Forget-Me-Not that will automatically set off an alarm if no one is around for an extended period of time. 

This not only earned Machnes a top placement at her regional science fair (beating out older students) but it’s now something she hopes to patent (along with a phone app) that would be implemented into long-term care homes. 

The invention is something that Jesse Clair, one of Machnes’ science teachers, calls a great example of how, even in a school environment, students can “get their hands dirty” to “work on actual real-world problems.” 

A growing need for everyday safety solutions

Machnes’ device taps into a very real and increasing need. Dementia affects millions of people worldwide, and one of the most pressing concerns for families and caregivers is safety in the home when individuals are left without supervision. Everyday tasks like cooking can become dangerous when memory lapses occur. Devices like the Forget-Me-Not aim to bridge that gap, offering a layer of protection without taking away independence.

Other innovations are addressing similar concerns. Smart stove shut-off systems, for example, can automatically turn off burners if no movement is detected nearby. Wearable GPS trackers help caregivers locate loved ones who may wander. Some companies have even developed simplified communication tablets designed specifically for those with cognitive decline, allowing users to connect with family through easy-to-navigate interfaces.

Breakthroughs in dementia research

Beyond assistive devices, scientific research is making unprecedented progress in understanding and treating dementia. In recent years, new medications and lifestyle changes have been developed that may slow cognitive decline in patients with early-stage Alzheimer’s disease. In some cases, these changes may even prevent it entirely.

Similarly, advancements in brain imaging have improved early detection, giving patients and families more time to plan and seek treatment. There is also growing interest in personalized care approaches, which tailor therapies to an individual’s specific condition and history. 

When science fair ideas change lives

Science fairs have long been the starting point for inventions just like Machnes’ that later found real-world applications. One well-known example is a student-designed early warning system for heart attacks that used simple sensors to detect irregular patterns. Another young inventor created a low-cost water purification system that has since been adapted for use in communities lacking clean drinking water.

These projects often begin with a personal experience, much like Machnes’ story. A problem at home or in the community becomes the catalyst for experimentation. With guidance from teachers and access to basic tools, students can transform these creative ideas into tangible solutions. It really is a team effort. 

A single door can open up a world of endless possibilities. For homeowners, the front door of their house is a  gateway to financial stability, job security, and better health. Yet for many, that door remains closed. Due to the rising costs of housing, 1 in 3 people around the world wake up without the security of safe, affordable housing. 

Since 1976, Habitat for Humanity has made it their mission to unlock and open the door to opportunity for families everywhere, and their efforts have paid off in a big way. Through their work over the past 50 years, more than 65 million people have gained access to new or improved housing, and the movement continues to gain momentum. Since 2011 alone, Habitat for Humanity has expanded access to affordable housing by a hundredfold. 

A world where everyone has access to a decent home is becoming a reality, but there’s still much to do. As they celebrate 50 years of building, Habitat for Humanity is inviting people of all backgrounds and talents to be part of what comes next through Let’s Open the Door, a global campaign that builds on this momentum and encourages people everywhere to help expand access to safe, affordable housing for those who need it most. Here’s how the foundation to a better world starts with housing, and how everyone can pitch in to make it happen. 

Globally, almost 3 billion people, including 1 in 6 U.S. families, struggle with high costs and other challenges related to housing. A crisis in itself, this also creates larger problems that affect families and communities in unexpected ways. People who lack affordable, stable housing are also more likely to experience financial hardship in other areas of their lives, since a larger share of their income often goes toward rent, utilities, and frequent moves. They are also more likely to experience health problems due to chronic stress or environmental factors, such as mold. Housing insecurity also goes hand-in-hand with unstable employment, since people may need to move further from their jobs or switch jobs altogether to offset the cost of housing. 

Affordable homeownership creates a stable foundation for families to thrive, reducing stress and increasing the likelihood for good health and stable employment. Habitat for Humanity builds and repairs homes with individual families, but it also strengthens entire communities as well. The MicroBuild® Initiative, for example, strengthens communities by increasing access to  loans for low-income families seeking to build or repair their homes. Habitat ReStore locations provide affordable appliances and building materials to local communities, in addition to creating job and volunteer opportunities that support neighborhood growth. 

Everyone can play a part in the fight for housing equity and the pursuit of a better world. Over the past 50 years, Habitat for Humanity has become a leader in global housing thanks to an engaged network of volunteers—but you don’t need to be skilled with a hammer to make a meaningful impact. Building an equitable future means calling on a wide range of people and talents.Here’s how you can get involved in the global housing movement:

Speaking up on social media about the growing housing crisis 

Volunteering on a Habitat for Humanity build in your local community

Travel and build with Habitat in the U.S. or  in one of 60   countries where we work around the globe

Join the Let’s Open the Door movement and, when you donate, you can create your own personalized door 

Shop or donate at your local Habitat ReStore

Every action, big and small, drives a global movement toward a better future. A safe home unlocks opportunity for families and communities alike, but it’s volunteers and other supporters, working together with a shared vision, who can open the door for everyone.

According to the United Health Foundation, Louisiana is the least healthy state for women and children. For that state and many others, one major factor is the need to address the health of new mothers and their babies.

Most parents know how overwhelming it can feel to suddenly care for a newborn without much experienced help. With that in mind, New Orleans brought back house calls, sending nurses to support new mothers.

The program Family Connects New Orleans offers new mothers up to three in-home visits from a registered nurse for babies up to 12 weeks old. It allows nurses to check in on both the babies and their mothers to ensure they’re safe and healthy.

The nurses are also able to spot symptoms of postpartum depression earlier, allowing mothers to receive treatment sooner. According to Rosemary Westwood of WWNO, “About 10% of moms participating in the New Orleans program were eventually diagnosed with postpartum depression, compared with 6% of moms who did not get the visits.”

The nurses visit with supplies for the baby, perform examinations (such as checking the child’s weight), and help answer any questions from the mothers.

“We got to do some real things real differently, unless you like being number 50 all the time,” Dr. Jennifer Avegno, New Orleans’ health director, told NPR. “There is no more critical time and vulnerable time than right at birth and in the few weeks to months following birth.”

“You go, you have your delivery, you’re in the hospital and everything is there. You go home, there’s a bit of a honeymoon period, and then, for many women, you fall off a cliff,” Avegno told The Guardian. “It’s the time in your life when your resources are generally at their lowest. We often don’t know about it until you hit one of our systems later on, whether that’s child protection, whether it’s the ER, whether it’s substance use treatment.”

The program, which shows great potential for New Orleans, has found success in other states. When it was introduced in North Carolina, both mothers and their babies’ health significantly benefited from the home visits. In fact, a Duke University study of the program found that every dollar invested in the home visits saved $3.14 in healthcare billing before the child turned two.

@thatheitgirl Sometimes supporting a friend who’s deep in postpartum life feels overwhelming because you don’t always know what she needs or how to show up. That’s why this postpartum scale is such a game changer. I put together 17 simple, practical ways to use someone’s “number” to guide you; from knowing when to send help, to when to offer company, to when to just let her rest. It takes the guesswork out of supporting each other and makes showing up feel natural instead of awkward or intrusive. And even though I created this scale with postpartum moms in mind, it’s just as powerful for anyone navigating mental illness, chronic illness, burnout, or big emotional seasons. Sometimes people don’t have the words to explain where they’re at, but they can give you a number. That number can help you understand their capacity, their needs, and how to support them without pushing too hard. It’s a tool that builds connection, reduces isolation, and reminds all of us that we don’t need to struggle alone. #PostpartumSupport #MentalHealthTools #MaternalMentalHealth #SupportYourFriends ♬ Soft and minimal........
