Super Smellers

carscentsLast night the weather suddenly turned into a full on symphony as I made a dash from the train to the taxi rank; all at once rain started lashing, wind howling, lightning sheeting, thunder cracking, reaching a crescendo of hailstones crashing on the ground. It really was a case of elephants and lions rather than cats and dogs. I sank into the backseat of a taxi thankful I did not have to wait. The inclement weather was mercifully silenced and shut out by the slam of my door. Within seconds my nostrils were filled with a distinctive smell of almonds that turned to marzipan. Before I knew it, I was being transported back to childhood memories of eating Christmas cake.

Because it was such an unusual and strong smell, I mentioned it to the cab driver who guffawed:

“All the girls say that. Smelling of almonds and then marzipan. It is actually Coronado Cherry.”

I sniffed again and tried hard to think of cherries and sure enough I began to detect some different notes.

“Yes, it is cherries like you taste in Dr Pepper!”
I chirped.

He laughed heartily again.

He replied “It is funny because men usually say it smells of chocolate.”

We then got into a very animated conversation about the difference between men and women’s ability to smell. He reckoned that 9.5 out of 10 women say it smells like almonds while 9 out of 10 men say it is like chocolate. His sample is based on the 10-20 customers he picks up a day over the last 3 years he has been buying his tubs of California Coronado Cherry. What is more, he doesn’t ask them directly, but just waits for them to say something about what they can smell. Just like with me that sets him off. What a wonderful icebreaker I mused.

But not only that, it is a lot of data collected ‘in the wild’ that shows a massive gender difference. I had no idea we were so different in our ability to identify smells. Whether women are better is another matter since we all seem to think his car smells more almond than cherry.

littletreeI’ve always thought car air fresheners are a bit naff. My memory of cardboard pine trees in a variety of colours dangling from rearview mirrors is that they were always overpowering and unpleasant – artificial sickly sweet. Reminded me of when I was 16 – and the first time I went on a date with Aaron the carpet-layer from Luton – who had a couple hanging in his Ford Cortina. Whatever was I doing…

carscent2When I bought my Scirocco a couple of years ago, it had that horrible new car smell of plastic and rubber. It never seemed to fade, so I caved in and went to Halfords in search of a car freshener to mask it. I was amazed to discover just how many different kinds of exotic trees, sticks, sprays, and tubs of super smelly gunk there are now to fill our cars with fragrance. Seems the marketing departments have gone overboard with Tropicana scents that conjure up drinking cocktails on a beach. All of them had exotic sounding names with the likes of “Jelly bean Margarita”, “Bahama Aruba Blue Breeze” and “Bahama Waikiki Wild Hibiscus Vent Sticks.” I bought a stick that promised the taste of Pina Colada – coconuts and pineapple. After taking the wrapper off, however, it smelt more like the Costa del Sol than fresh fruits. It was awful. I had to throw it out and keep the car windows open for a couple of weeks to get rid of the new smell.

As we neared home, my taxi driver regaled how he has met women who could even name the make and brand of perfume others are wearing. What must it be like to be a super smeller?

Pigeon Carriers

pigeonI came across an article in the news about using pigeons to monitor air pollution levels in London. 12 carrier pigeons have each been strapped with a backpack full of sensor technologies that can detect nitrogen oxide and other gases. It seems pretty harmless and rather cute at first imagining such birds helping humans to discover how polluted our city is (or not) in places where it would be impossible or very difficult to find out otherwise. Maybe we will discover that it is more polluted at the top of Nelson’s column than in the grounds of Buckingham Palace – when we might have assumed the opposite. Maybe the birds will ‘understand’ their mission to learn more and swoop down into all sorts of unexpected places, including inside churches, shopping malls and onto the smelly platforms at Kings Cross.

While seemingly benign, something irked me about the use of animals in this way for human interest. Is it right? Has anyone asked the pigeons if they minded acting as mules? Surely, it would be uncomfortable for the pigeons flying whilst wearing all that kit? Plamena Panova tweeted the same concern as me:
“@PigeonAir How safe are your backpacks for the pigeons? Do they cause them pain or discomfort?” Apparently, the carrier pigeons only had to wear their backpacks for three days during the experiment and then they were removed.

bees_3370425bAnother project has been using bees to monitor the air quality of industrally polluted areas. Bees generate a lot of static electricity that results in molecules from pollen sticking to their wings, legs and abdomen. Tiny particles that are hard to detect can also be picked up by the bees providing a way of measuring local levels of pollution. The researchers have been using bees to discover more about the pollution levels of an industrial area of Sardinia where there used to be lead-zinc mines operating until a few years back. While the bees in this case can fly around unfettered they still are breathing the polluted air.

But it is not just bees and pigeons that are now becoming our roaming sensors but all manner of animals. From elephants to whales to ducks – all are being donned with electronic gear and often for much longer periods in the pursuit of science. The benefits are obvious – providing us humans with more detailed data about the gases around us, climate change or more about the animal’s own migration patterns and predatory/sexual behaviors. Scientists are having a field day finding out more about what dolphins, bats and ants get up to in their natural habitats.

The scientists argue that this kind of pervasive data collection is invaluable. Moreover, they reassure us that the animals are not being harmed in anyway. Let’s hope they are right. After all, donkeys, packhorses and mules have been carrying infinitely heavy loads for our needs for centuries. The pigeon backpacks are featherweight in comparison.

We often go to great lengths to debate the ethics of whether humans should be monitored or monitor on behalf of others (e.g. workers wearing sensor vests to collect environmental data in warehouses) but we rarely question whether if it is OK to use animals to do the same. Of course it would be easier if we could simply ask the animals if they mind.

drone-swarm-2 swarmingPerhaps, in the not too distant future those drones, that are becoming commonplace in our parks, will take over our monitoring needs. And we might get to watch them as wings of beauty instead of as noisy pesky devices – that they currently are. Rather than watching a flock of starlings swarming in formation against a beautiful sunset we might one day be in awe of a swarm of flying drones performing breathtaking air display acts.
