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.

A worker digging up clay in a southern England limestone quarry noticed unusual bumps that led to the discovery of a “dinosaur highway” and nearly 200 tracks that date back 166 million years, researchers said Thursday.

The extraordinary find made after a team of more than 100 people excavated the Dewars Farm Quarry, in Oxfordshire, in June expands upon previous paleontology work in the area and offers greater insights into the Middle Jurassic period, researchers at the universities of Oxford and Birmingham said.

“These footprints offer an extraordinary window into the lives of dinosaurs, revealing details about their movements, interactions, and the tropical environment they inhabited,” said Kirsty Edgar, a micropaleontology professor at the University of Birmingham, The AP reported.

Four of the sets of tracks that make up the so-called highway show paths taken by gigantic, long-necked, herbivores called sauropods, thought to be Cetiosaurus, a dinosaur that grew to nearly 60 feet (18 meters) in length. A fifth set belonged to the Megalosaurus, a ferocious 9-meter predator that left a distinctive triple-claw print and was the first dinosaur to be scientifically named two centuries ago.

An area where the tracks cross raises questions about possible interactions between the carnivores and herbivores.

“Scientists have known about and been studying Megalosaurus for longer than any other dinosaur on Earth, and yet these recent discoveries prove there is still new evidence of these animals out there, waiting to be found," said Emma Nicholls, a vertebrate paleontologist at the Oxford University Museum of Natural History.

Nearly 30 years ago, 40 sets of footprints discovered in a limestone quarry in the area were considered one of the world's most scientifically important dinosaur track sites. But that area is mostly inaccessible now and there's limited photographic evidence because it predated the use of digital cameras and drones to record the findings.

The group that worked at the site this summer took more than 20,000 digital images and used drones to create 3-D models of the prints. The trove of documentation will aid future studies and could shed light on the size of the dinosaurs, how they walked and the speed at which they moved.

“The preservation is so detailed that we can see how the mud was deformed as the dinosaur’s feet squelched in and out," said Duncan Murdock, an earth scientist at the Oxford museum. "Along with other fossils like burrows, shells and plants we can bring to life the muddy lagoon environment the dinosaurs walked through.”

The findings will be shown at a new exhibit at the museum and also broadcast on the BBC's “Digging for Britain” program next week.
