3 . Mark Bertram, 46, lost the tips of two fingers at work in 2018 when his hand became trapped in a fan belt. “It's life-changing but it's not life-ending,” he says. “Doing work is harder now. Everything is just a little different.”
After two surgeries and occupational therapy, Bertram decided to make light of his condition by asking Eric Catalano, a tattoo (纹身) artist, to create fingernail tattoos. The idea made everyone in the studio laugh—until they saw the final result. “The mood changed,” Catalano recalls from his Eternal Ink Tattoo Studio. “Everything turned from funny to wow.”
When Catalano posted a photo of the tattoos, a pair of fingernails that looked so real that no one could believe their eyes, he had no idea the image would eventually be viewed by millions of people around the world.
The viral photo pushed Catalano, 40, further into the world of paramedical (辅助医疗的) tattooing. Now people with life-altering scars come from as far away as Ireland to visit his shop. They enter Eternal Ink looking for the artistic healing they saw online. Using flesh-toned (肉色的) inks and a needle, Catalano transforms his clients' view of themselves.
Leslie Pollan, 32, a dog breeder in Oxford, was bitten on the face by a puppy in 2014. She underwent countless surgeries to correct a scar on her lip.
“Plastic surgery gave me no hope,” she says. “So I looked for other options.” She ultimately traveled six hours to meet with Catalano. He hid Pollan's lip scar, giving her back a piece of her confidence.“ You don't understand until you've been through it,” Pollan says. “It made me have a different look on life.”
Catalano performs up to eight reconstructive tattoos. While he charges $100 per regular tattoo, he doesn't charge for paramedical tattoos. “Financially, it doesn't make sense,” Catalano says. “But every time I see that emotion from my customers, I'm 100 percent sure this is something that I can't stop doing.”

4 . Your dentist has probably been telling you to floss for years.
That’s why many cheered at a news report that flossing might not be necessary. The Associated Press reviewed 25 studies and concluded that flossing didn’t have proven health benefits. Should you throw away your floss? Not so fast.
One review of 12 studies found that people who brushed and flossed regularly were less likely to have bleeding gums.
In fact, many dentists say the reason they recommend flossing isn’t because of research.
| A．Many dental experts aren’t on board. |
| B．There are also many benefits in flossing. |
| C．They had lower levels of gum disease, too. |
| D．If you’ve refused to do so, you’re not alone. |
| E．Instead, it’s because of what they see in their patients. |
| F．It takes seven or more years to train a professional dentist. |
| G．The connection between gum disease and health isn’t entirely clear. |
5 . Have you ever said to a friend “That rose’s smell is really sweet!”, only to find that your friend can’t smell anything at all?
According to a study published in the journal PNAS in May, people have different abilities to recognize certain odors (气味) — and it’s linked to different genes.
For the study, 300 people were placed among 150 jars with different odors. At a given time, they had to smell an odor and then rate the intensity (强度) and pleasantness of the odor on a scale from 1 (extremely weak/unpleasant) to 7 (extremely strong/pleasant). Before they left, the participants needed to leave a blood sample.
After comparing genes of the participants, researchers found all had different smelling abilities and that the differences between these abilities could be traced to certain genes.
According to The New York Times, human beings have nearly 400 genes that directly control receptors (器官) and influence the way these receptors become active.
“Odors ... turn on specific receptors, which then tells us if we’re smelling a flower, how strong we find it, and whether we like it,” said Casey Trimmer, a geneticist and the lead author of the study. “One small change in the gene for the receptor can change its shape and how well the odor fits, thereby changing the awareness of the odor.”
Though genes play a decisive role in our ability to smell, other factors, including attention, past associations and expectations, are important as well. For example, if we love the smell of roses, we are drawn to their smell and pay special attention to it.
But what does our different abilities to sense odors mean?
“Smelling is the most important sense for the rest of the animal kingdom,” said Trimmer. Although, unlike other animals, humans aren’t any longer dependent on their sense of smell to find food or detect danger, smell is still a significant sense. There is also evidence that a reduced sense of smell is an early symptom of Alzheimer’s disease.
