7 . International scientists have found that people from different cultures around the world like and dislike the same kinds of smells.

The researchers, from Oxford University and the Karolinska Institute in Sweden, tested smell preferences in 235 people. “We wanted to examine if people around the world have the same smell perception (感知能力) and like the same types of smell, or whether this is something that is culturally learned,” said the study author Dr. Artin Arshamian.

The scientists took 10 different scents and presented them to 235 people from nine different cultures to find out what was universally loved and hated. Dr. Arshamian said the people lived in various places, including rainforests, coasts, mountains and cities, and were therefore exposed to very different smells. The 235 people were asked to rank smells on a scale of pleasant to unpleasant. Different people within each group had their own preferences, but there were very few differences between the groups overall.

Vanilla was consistently ranked the most pleasant smell by the groups, followed by peaches and lavender. The least pleasant smell was isovaleric acid (异戊酸), which is found in many foods, such as cheese, soy milk and apple juice, but also in foot sweat.

“The smells we like or dislike are partly determined by personal preference but also by the molecular structure, or chemical makeup of the particular smell, which explains why we like or dislike a certain smell,” said the scientists.

8 . Artworks get dirty. Art that has been around for centuries gets even dirtier. If any art is cleaned too often or with some harmful chemical materials, it can be ruined in an instant. In Italy, some scientists were tasked with cleaning status by Michelangelo at the Medici Chapels. They knew that just using soap and water wasn’t going to work because there were too many layers of dirt on them. So, what did they do? They made bacteria, which have traditionally been viewed as a threat to art, do the dirty work.

Michelangelo’s marble statues have been stained since the 16th century. Experts could not use a common chemical cleaner because it would easily cause great damage to or even destroy the details of the valuable pieces. Luckily, scientists developed a substance with bacteria that could eliminate the dirt without damaging the marble. The scientists tested several kinds of bacteria on small pieces of marble before finding the one that worked best to swallow the dirt. After seeing positive effects, they later applied the bacteria to whole statues. In the end, the substance turned out to be very effective. It is now considered the best way to get such statues to look new again.

After the special treatment, the statues began to glow again and visitors were impressed when admiring them. While the works will never look exactly the same as they did 500 years ago when they were first made and brand new, at least they now look much better.
