Beauty brands are looking to research and technology to sniff out the factors that lure buyers, according to a report by The Guardian.

Making perfume is an art that can be traced back to ancient Greece but now modern-day perfumiers are beginning to look beyond their noses to develop the scents most likely to appeal to us. They are, instead, turning to AI.

Perfumes can now be designed to trigger emotional responses using ingredients known as neuroscents – odors shown by biometric measures to arouse different positive feelings such as calm, euphoria or sleepiness. Hugo Ferreira, a researcher at the Institute of Biophysics and Biomedical Engineering in Lisbon, is mapping brain activity and response to perfumes to build a database of neuroscents.

He says the sense of smell is fascinating. “With sight and hearing, you can imagine the face of a loved one or favorite tune. It’s hard to imagine a smell even though it can provoke a torrent of emotions and memories.”

Ferreira says this is due to the structure of the olfactory system. Messages from scent receptors are sent via the olfactory bulb to different brain areas that control everything from memory or thirst to stress reactions.

“Olfaction is the most diverse sense with many different receptors. It’s estimated that there are about 400 different olfactory receptor gene families. Among other things these various connections may explain how we can ‘smell fear’, or the smell of victory,” he added.

Many beauty brands have invested in neuroscent research and technology, as the possibilities of creating fragrances proven to make consumers feel good are obviously big. L’Oréal has partnered with neurotechnology company Emotiv to create a scent choice “experience”.

During 2023, shoppers at certain Yves Saint Laurent stores worldwide have used a headset to create an electroencephalogram – EEG – to discover which scents appealed to them. Results so far show that 95% of customers who used the headset found the right perfume.

Fashion and fragrance business Puig says it took 45 million brain readings from men aged 18-35 to finesse the cologne Phantom by Paco Rabanne, adding lavender and lemon to the formula as a result of its research.

Givenchy Irresistible eau de parfum – the latest iteration of the Very Irresistible range that has been a bestseller for 20 years – includes a rose extract dubbed “anti-morose”, chosen after biometric research.

Marseille Airport Suspends Flights Due to Wildfire as Public Warned to Stay at Home

A wildfire spurred by hot summer winds reached France's second-largest city Tuesday, grounding all flights to and from Marseille, injuring at least nine people and forcing many residents to evacuate or barricade themselves indoors as smoke choked the Mediterranean air.

A big city hospital switched to generator power, train traffic was halted in most of the surrounding area, and some roads were closed and others tangled with logjams.

More than 1,000 firefighters were deployed to tackle the fire, which broke out near the town of Les Pennes-Mirabeau before racing toward Marseille. Some 720 hectares (acres) were hit by the blaze, the prefecture said.

Nine firefighters were injured, according to the prefecture, or local administration. No dead have been reported.

The prefecture said in a statement Tuesday evening that “the situation is under control,″ though the fire has not yet been extinguished. It described the fire as “particularly virulent.″

It came on a cloudless, windy day after a lengthy heat wave around Europe left the area parched and at heightened risk for wildfires. Several have broken out in southern France in recent days.

Light gray smoke gave the sky over Marseille’s old port a dusty aspect as water-dropping planes tried to extinguish the fire in the outskirts of the city, which has some 900,000 inhabitants.

Hundreds of homes were evacuated. The prefecture urged people in the affected areas to stay indoors and off the roads. With the fire approaching Marseille, the prefecture also advised residents in the north of the city to keep windows closed to prevent toxic smoke from entering their homes.

One distressed family watched the smoke over their neighborhood in the hills above the port city and showed AP how the roof of their neighbor's house had been damaged in the fire as they worried about their own.

Marseille airport announced that the runway had been closed at around midday. The prefecture said train traffic was halted, notably after a fire neared the tracks in L'Estaque, a picturesque neighborhood of Marseille.

As a safety measure, the city's Hospital Nord switched to generators “due to micro power cuts.”

“The aim is to secure the imaging sector. We are not worried as we have a high level of autonomy,” the University Hospitals of Marseille said, adding that because of the disrupted traffic it asked workers to remain at their posts until the next teams starts its shift.
