Pinocchio may be just a children's fairy tale, but Spanish scientists at the University of Granada recently investigated the so-called ''Pinocchio effect'' and found that our noses don't grow when we tell a lie, but actually shrink a bit.
Dr. Emilio Gómez Milán and his team developed a lie detector test that used thermography to tell if people were lying, and found that whenever participants in their research were being untruthful, the temperature of the tips of their noses dropped up to 1.2℃, while the temperature of their forehead increased up to 1.5℃. Scientists also found that drop in temperature at nose level actually caused it to slightly shrink, although the difference is undetected by the human eye.
''One has to think in order to lie, which rises the temperature of the forehead, '' Dr. Gomez Milan explained the findings. ''At the same time we feel anxious, which lowers the temperature of the nose. ''
For this study, researchers asked a number of 60 students to perform various tasks while being scanned by thermal imaging technology. One of these tasks involved calling a 3 to 4 minutes call to their parents, partner or a friend and telling a significant lie. Participants had to devise the lie by themselves during the call, and the thermal cameras picked up this ''reverse Pinocchio effect'' caused by the fluctuation (起伏) in temperature in the nose and forehead.
Interestingly, the thermal lie doctor picked up the temperature difference in 80 percent of test subjects, which is a better rate of success than that of any modern lie doctor.
''With this method we have achieved to increase accuracy and reduce the occurrence of 'false positives', something that is frequently with other methods such as the polygraph (测谎仪) , '' said Dr. Emilio Gómez Milán, who added that law enforcement interviewers could one day combine other lie detection technology with thermal imaging to achieve better results.
The thermal lie doctor has been the most reliable in the world, 10% more than the popular polygraph.

If plastic had been invented when the Pilgrims (清教徒移民) sailed from Plymouth, England, to North America and the Mayflower had been stocked with bottled water and plastic-wrapped snacks, their plastic waste would likely still be around, four centuries later. If the Pilgrims had been like many people today and had simply thrown their empty bottles and wrappers over the side, Atlantic waves and sunlight would have worn all that plastic into tiny bits. And those bits might still be floating around the world’s oceans today, waiting to be eaten by unfortunate fish, and eventually perhaps by one of us.
Because plastic wasn’t invented until the late 19th century, and production really only took off around 1950, we have a mere 9.2 billion tons of the stuff to deal with. Of that, more than 6.9 billion tons have become waste. And of that waste, a shocking 6.3 billion tons never made it to recycling facilities.
No one knows how much unrecycled plastic waste ends up in the ocean, Earth’s last sink. In 2015, Jenna Jambeck, a university of Georgia engineering professor, caught everyone’s attention with a rough estimate: between 5.3 million and 14 million tons each year just from coastal regions. Most of it isn’t thrown off ships, she and her colleagues say, but is dumped carelessly on land or in rivers, mostly in Asia. It’s then blown or washed into the sea. It’s unclear how long it will take for that plastic to completely biodegrade (降解). Estimates range from 450 years to never.
Meanwhile, ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. Some are harmed visibly-strangled (勒死) by abandoned fishing nets. Many more are probably harmed invisibly. Marine species of all sizes, from fish to whale, now eat microplastics, the bits smaller than one-fifth of an inch across. On Hawaii’s Big Island, on a beach to which no paved road, I walked ankle-deep through mocroplastics. After that, I could understand why some people see ocean plastic as an approaching disaster, worth mentioning in the same breath as climate change.
And yet there’s a key difference: Ocean plastic is not as complicated as climate change. There are no mean waste deniers (否认者), at least so far. To do something about it, we have to remake our planet’s entire energy system.
“This isn’t a problem where we don’t know what the solution is,” says Jambeck. “We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle.” It’s a matter of building the necessary institutions and systems, she says--ideally before the ocean tums, for centuries to come, into a thin soup of plastic.
