Her "weird" dog wouldn't stop sniffing her breath. It saved her life.

Dogs can be weird. Any dog owner will tell you that, but typically their shenanigans are just personality quirks. Unfortunately for Colleen Ferguson of Kent, England, her dog’s weird behavior wasn’t just a silly personality thing.

For several weeks, Ferguson’s German Shepherd was obsessively sniffing her mouth. This was a new behavior that she found quite odd. The dog, Inca, was only two years old, but she seemed to know something was wrong with her owner and was doing her best to let her know. Inca constantly sniffed around Ferguson’s mouth and frowned.

The dog’s persistence caused the then 60-year-old woman to become concerned, which led her to the dentist. Everything checked out fine, but Inca was still frowning after sniffing Ferguson’s mouth. This prompted Ferguson to visit her doctor to be tested for other things that might change the smell of her breath.

According to Medical News Today, diabetes can cause the breath to smell differently. Gluten intolerance and Celiac disease can also cause bad breath, according to Imperial Dental Center. Ferguson was cleared of any gut-related issues after tests from her doctor. Yet Inca would not stop telling her something was wrong. Growing more concerned about her dog’s new behavior, Ferguson decided to do a full-body scan to rule out anything unusual.

“Her behavior towards me changed, she just started homing in on my mouth. Every time she could get a sniff of my mouth she would frown,” Ferguson told The Mirror. “She just had this focused intent on my mouth, and you couldn’t push her away until you had done an outbreath. When she got that she would give me such a look and walk away. In no way did I expect lung cancer at all. It was such a shock because I am a non-smoker, and because I taught biology, I was very anti-smoking.”

Turns out, Inca was trying to tell her she had a tumor growing in her lungs. Thanks to the dog’s keen nose and insistent behavior, Ferguson was able to catch the cancer early. Before long, the science teacher was off to surgery, where doctors removed a golf-ball-sized tumor.

“The surgeon said…’that dog saved your life. We never catch it at stage one,’” Ferguson told the BBC.

This remarkable discovery took place in 2015, and since then scientists have been working on recreating a nose like Inca’s. The Massachusetts Institute of Technology is currently developing an “e-nose,” a mechanical nose that scientists are training with AI to detect cancer. They have moved to the trial phase, testing more than 500 urine samples to see if the artificial nose is as accurate as a dog’s nose in detecting cancer.

Dr. Andreas Mershin, a quantum physicist, developed the device that will be used to screen donated urine samples. The samples were prescreened by Medical Detection Dogs, and the results of the e-nose will be compared with those of the dogs.

“This is a major milestone,” Mershin told Medical Detection Dogs. “We’ve worked to emulate the dogs’ abilities and train machines in a similar way—rewarding them for correct identifications. It’s like giving our devices a new sense: a nose. Phones already have eyes and ears, but machine olfactors are the next frontier in health technology and AI sensing. This could transform the world of diagnosis, screening, and early detection.”

While the e-nose is currently designed to detect prostate cancer, once it’s perfected, the mechanical nose will hopefully detect other cancers as well.

Ferguson, for one, is thankful that her dog’s nose detected her lung cancer early, giving her a renewed chance at life.

“I was just so lucky,” she told The Mirror. “Every day is special with her. To catch it at stage one is just remarkable. I don’t know how I would have survived with radiotherapy and chemotherapy. She saved me a lot of fuss. It was meant to be.”

  • Follow the spark: Genuine curiosity must drive your personal curriculum. If you hated calculus in high school, don’t pick it up again for arbitrary reasons, like trying to feel smart. Look for subjects that make you lose track of time. Identifying every tree in your neighborhood could be one, or mastering the perfect sourdough loaf.
  • Diversify your materials: Learning exists everywhere, not solely in dense textbooks. Keep required texts engaging and fun, mixing in podcasts, workshops, flashcards, and documentaries. If you are learning a new language, listen to an album in that language. If you’re studying paleontology, visit a local natural history museum.
  • Set the scene: Get yourself in the zone with a little learning mise en place. Find a specific chair and reserve it for reading, or flipping through flashcards. Make a study playlist and fill it with songs to play in the background. When you sit in that chair, or hit play, you are signaling to your brain that it’s time to switch into “student” mode.

Music, community and joy drive real change

In a small village in Pwani, a district on Tanzania’s coast, a massive dance party is coming to a close. For the past two hours, locals have paraded through the village streets, singing and beating ngombe drums; now, in a large clearing, a woman named Sheilla motions for everyone to sit facing a large projector screen. A film premiere is about to begin.

It’s an unusual way to kick off a film about gender bias, inequality, early marriage, and other barriers that prevent girls from accessing education in Tanzania. But in Pwani and beyond, local organizations supported by Malala Fund and funded by Pura are finding creative, culturally relevant ways like this one to capture people’s interest.

The film ends and Sheilla, the Communications and Partnership Lead for Media for Development and Advocacy (MEDEA), stands in front of the crowd once again, asking the audience to reflect: What did you think about the film? How did it relate to your own experience? What can we learn?

Sheilla explains that, once the community sees the film, “It brings out conversations within themselves, reflective conversations.” The resonance and immediate action create a ripple effect of change.

Across Tanzania, gender-based violence often forces adolescent girls out of the classroom. This and other barriers — including child marriage, poverty, conflict, and discrimination — prevent girls from completing their education around the world.

Sheilla and her team are using film and radio programs to address the challenges girls face in their communities. MEDEA’s ultimate goal is to affirm education as a fundamental right for everyone, and to ensure that every member of a community understands how girls’ education contributes to a stronger whole and how to be an ally for their sisters, daughters, granddaughters, friends, nieces, and girlfriends.

Sheilla’s story is one of many that inspired Heart on Fire, a new fragrance from the Pura x Malala Fund Collection that blends the warm, earthy spices of Tanzania with a playful, joyful twist. Here’s how Pura is using scent as a tool to connect the world and inspire action.

A partnership focused on local impact, on a global mission

Pura, a fragrance company that recognizes education as both freedom and a human right, has partnered with Malala Fund since 2022. In order to defend every girl’s right to access and complete 12 years of education, Malala Fund partners with local organizations in countries where the educational barriers are the greatest. They invest in locally-led solutions because they know that those who are closest to the problems are best equipped to solve and build durable solutions, like MEDEA, which works with communities to challenge discrimination against girls and change beliefs about their education.

But local initiatives can thrive and scale more powerfully with global support, which is why Pura is using their own superpower, the power of scent, to connect people around the world with the women and girls in these local communities.

The Pura x Malala Fund Collection incorporates ingredients naturally found in Tanzania, Nigeria, Pakistan, and Brazil: countries where Malala Fund operates to address systemic education barriers. Eight percent of net revenue from the Pura x Malala Fund Collection will be donated to Malala Fund directly, but beyond financial support, the Collection is also a love letter to each unique community, blending notes like lemon, jasmine, cedarwood, and clove to transport people, ignite their senses, and help them draw inspiration and hope from the global movement for girls’ education. Through scent, people can connect to the courage, joy, and tenacity of girls and local leaders, all while uniting in a shared commitment to education: the belief that supporting girls’ rights in one community benefits all of us, everywhere.

You’ve already met Sheilla. Now see how Naiara and Mama Habiba are building unique solutions to ensure every girl can learn freely and dare to dream.

Naiara Leite is reimagining what’s possible in Brazil

In Brazil, where pear trees and coconut plantations cover the Northeastern Coast, girls like ten-year-old Julia experience a different kind of educational barrier than girls in Tanzania. Too often, racial discrimination contributes to high dropout rates among Black, quilombola and Indigenous girls in the country.

“In the logic of Brazilian society, Black people don’t need to study,” says Naiara Leite, Executive Coordinator of Odara, a women-led organization and Malala Fund partner. Bahia, the state where Odara is based, was once one of the largest slave-receiving territories in the Americas, and because of that history, deeply-ingrained, anti-Black prejudice is still widespread. “Our role and the image constructed around us is one of manual labor,” Naiara says.

But education can change that. In 2020, with assistance from a Malala Fund grant, Odara launched its first initiative for improving school completion rates among Black, quilombola, and Indigenous girls: “Ayomidê Odara”. The young girls mentored under the program, including Julia, are known as the Ayomidês. And like the Pura x Malala Fund Collection’s Brazil: Breath of Courage scent, the Ayomidês are fierce, determined, and bursting with energy.

Ayomidês take part in weekly educational sessions where they explore subjects like education and ethnic-racial relations. The girls are encouraged to find their own voices by producing Instagram lives, social media videos, and by participating in public panels. Already, the Ayomidês are rewriting the narrative on what’s possible for Afro-Brazilian girls to achieve. One of the earliest Ayomidês, a young woman named Debora, is now a communications intern. Another former Ayomidê, Francine, works at UNICEF, helping train the next generation of adolescent leaders. And Julia has already set her sights on becoming a math teacher or a model.

“These are generations of Black women who did not have access to a school,” Naiara says. “These are generations of Black women robbed daily of their dreams. And we’re telling them that they could be the generation in their family to write a new story.”

Mama Habiba is reframing the conversation in Nigeria

In Mama Habiba’s home country of Nigeria, the scents of starfruit, ylang ylang and pineapple, all incorporated into the Pura x Malala Collection’s “Nigeria: Hope for Tomorrow,” can be found throughout the vibrant markets. Like these native scents, Mama Habiba says that the Nigerian girls are also bright and passionate, but too often they are forced to leave school long before their potential fully blooms.

​​“Some of these schools are very far, and there is an issue of quality, too,” Mama Habiba says. “Most parents find out when their children are in school, the girls are not learning. So why allow them to continue?”

When girls drop out of secondary school, marriage is often the alternative. In Nigeria, one in three girls is married before the age of 18. When this happens, girls are unable to fulfill their potential, and their families and communities lose out on the social, health and economic benefits.

Completing secondary school delays marriage, and according to UNESCO, educated girls become women who raise healthier children, lift their families out of poverty and contribute to more peaceful, resilient communities.

To encourage young girls to stay in school, the Centre for Girls’ Education, a nonprofit in Nigeria founded by Mama Habiba and supported by Malala Fund and Pura, has pioneered an initiative that’s similar to the Ayomidê workshops in Brazil: safe spaces. Here, girls meet regularly to learn literacy, numeracy, and other issues like reproductive health. These safe spaces also provide an opportunity for the girls to role-play and learn to advocate for themselves, develop their self-image, and practice conversations with others about their values, education being one of them. In safe spaces, Mama Habiba says, girls start to understand “who she is, and that she is a girl who has value. She has the right to negotiate with her parents on what she really feels or wants.”

“When girls are educated, they can unlock so many opportunities,” Mama Habiba says. “It will help the economy of the country. It will boost so many opportunities for the country. If they are given the opportunity, I think the sky is not the limit. It is the starting point for every girl.”
