8 Interesting Science Tales from 2018 Because You Probably Need It

1. Crocodiles Were Played Classical Music.

A group of international researchers scanned Nile crocodiles in MRI scanners while playing classical music to see how their brains handle complicated sensory information.

The researchers played Bach music to the crocodiles while also exposing them to sophisticated visual cues.

The study discovered that the brains of crocodiles, which evolved more than 200 million years ago, exhibited distinct brain activation after being exposed to sophisticated noises such as classical music versus when they were exposed to simple sounds.

The findings showed that this sophisticated sensory processing originated far earlier than scientists previously believed.

2. Asian Elephants Are Extremely Good at Counting.

According to research published in the Journal of Ethology in October, Asian Elephants exhibit mathematical ability that is more similar to humans than other species.

The researchers taught a 14-year-old Asian elephant to utilize a computer-controlled touch screen, which the elephant used its trunk to express numerical judgments.

The elephant picked the right answer 181 out of 271 times (66.8 percent of the time), indicating that it possesses cognitive powers equivalent to human counting.

3. Scientists Have Developed A Sensory System Small Enough To Ride On Bumblebees.

Engineers at the University of Washington have developed a sensor device that rides on the backs of bees to monitor temperature, humidity, and crop health.

Farmers may employ drones for this purpose, but they take a lot of electricity to fly over big fields, so they need to be recharged frequently.

The bumblebee sensory system includes position tracking, wireless communication, and a seven-hour battery that recharges as the bees sleep in their hives at night.

4. Scientists Rediscovered An Animal Not Seen In 30 Years.

The Mexican government proclaimed the San Quintin kangaroo rat, a tiny, feisty burrow-dwelling animal from northern Mexico, extinct in 1994.

However, four of the kangaroo rats were discovered by researchers during a routine survey in 2017 and their findings were published in May of this year.

According to the researchers, the kangaroo rat's comeback is an encouraging indicator that natural ecosystems in the Baja California area are rebounding after an agricultural boom severely altered the environment.

5. Three New Rainbow Chameleon Species Have Been Discovered.

On an expedition conducted by a German zoological association, three new species of rainbow chameleons were found on Madagascar's east coast.

According to the experts that found them, the three species are expected to have tiny populations with a limited range.

One of the chameleon species was only found in a 37-acre area of secluded jungle.

6. Goats Notice When People Smile And Like Seeing It.

Researchers studied goat intelligence in recognizing social cues in a study published by the Royal Society.

The scientists noticed preference when 35 goats were shown images of either an angry or a cheerful human expression.

The goats preferred to spend time near photos of joyful human faces, indicating for the first time that domesticated farm animals that haven't been raised particularly to engage with humans can detect facial communication signs in people.

7. Pterosaurs Were Most Likely Feathered.

Nanjing University in China undertook a study that microscopically studied fossils of pterosaurs, the flying reptiles that coexisted with dinosaurs, and discovered that they were covered in tiny feathers.

The unexpected discovery pushed back the origin of feathers by 70 million years. The feathers of pterosaurs were shorter and were not designed to aid flying like feathers on contemporary birds.

The finding led scientists to believe that pterosaurs were feathered rather than scaled in appearance.

8. Lizards Dream In The Same Way That We Do.

The Neuroscience Research Center of Lyon conducted a sleep study on lizards and discovered that they had different sleep phases similar to humans.

The researchers were looking at how lizards sleep to figure out how sleep states evolved in humans.

The study discovered that lizards go through stages that are comparable to human rapid-eye-movement (REM) and slow-wave sleep states.

The findings showed that lizards may have dreams in the same manner that humans do.
