Are you using a dating App to make friends? How do you know that Ben from London is really 25-year-old? Is his photo taken recently? Is his name even Ben? Dating apps can be tricky to operate, particularly when you’re trying to know whether someone is trustworthy, but one thing you can’t cheat is your gene, which is why a new dating app is using DNA as a basis for its match.
A dating app named Pheramor requires all users to hand in a cheek sample, from which a team of in-house scientists using a specially-created tool can queue the specific genes connected with attraction and then identify which users might be suitable. The process works by separating the 11 genes that link to our pheromones(信息素), the chemical signals that are believed to control; one’s attraction. Combining this data with the personal information allows the app to make very specific matches.
“Pheramor uses both your biology and your social technology: we collect your genetic data through a cheek sample and collect your like, dislikes, and interest from your social media introductions like Facebook, Twitter, etc,” the app’s website explains. “All of them will be used in our specific software, which is designed to learn what you prefer.”
The co-founder Brittany Barreto, who has a PHD in genetics added that Pheramor’s technology digs deeper than traditional dating apps, making it almost impossible for people to cheat their way to a date.
The Houston-based app is already up and running but hopes to be officially put into market in February with 3,000 members.

Researchers are only now starting to pay attention to the importance of friendship and social networks in overall health. A 10-year Australian study found that older people with a large circle of friends were 22 percent less likely to die during the study period than those with fewer friends. A large 2007 study showed an increase of nearly 60 percent in the risk for obesity among people whose friends gained weight. And last year, Harvard researchers reported that strong social ties could promote brain health as we age.
“In general, the role of friendship in our lives isn’ t well appreciated,” said Rebecca G. Adams, a professor of sociology at the University of North Carolina, Greensboro. “There are a lot of things on families and marriage, but very little on friendship. It baffles me. Friendship has a bigger impact on our psychological well being than family relationships.”
Bella DePaulo, a visiting psychology professor at the University of California, Santa Barbara, whose work focuses on single people and friendships, notes that in many studies, friendship has an even greater effect on health than a spouse or a family member.
It isn’ t entirely clear why friendship has such a big effect. It may be because people with strong social ties also have better access to health services and care. Beyond that, however, friendship clearly has a profound psychological effect. People with strong friendships are less likely than others to get colds, perhaps because they have lower stress levels.
Last year, researchers studied 34 students at the University of Virginia, taking them to the base of a steep hill and fitting them with a weighted backpack. They were then asked to estimate the steepness of the hill. Some participants stood next to friends during the exercise, while others were alone.
The students who stood with friends gave lower estimates of the steepness of the hill. And the longer the friends had known each other, the less steep the hill appeared.
“People with stronger friendship networks feel like there is someone they can turn to,” said Karen A.Roberto, director of the center for gerontology (老年医学) at Virginia Tech.“ Friendship is an undervalued resource. The consistent message of these studies is that friends make your life better.”

My parents and teachers-even some of my friends—think I’m quiet and shy, really smart but not very cool. In fact, that’s who I am when I am with them, but not who I really am. The real me comes out when I’m around guys who are more like me-like Tom Henderson and Graham Barry. I met Tom and Graham at a Young Scientist contest last y car. The three of us were among the five finalists. As soon as we met, we really hit it off.
As we talked about the conference, we discovered that all three of us were interested in space debris mitigation, which is the study of the prevention of space garbage damaging satellites and the new space station. It was great to meet other people my age who actually knew what I was talking about. When I talk about “space garbage,” most of the kids at my school just say, “Oh, you mean like asteroid-type (小行星之类的) things? I played a videogame about that once.”
Luckily, we met each other on the first day of the conference, so we were able to spend a lot of time together for the entire three days. We talked about everything from the best schools to go to, what degrees to get, and even the names of the best people in each field. We want to study with the pioneers. Both Tom and I want to study with Dr. Claude Phipps, the inventor of a project that developed a laser (光) that knocks down space garbage before it does any damage to expensive space vehicles. Graham wants to study under Didier Patrick Queloz, the physics Nobel winner from the University of Cambridge.
Even though the three of us don’t get a chance to see each other very often, we’re still the best of friends. We call each other a couple of times a month. I always feel happy when I talk with Tom and Graham. It’s like the other person in me wakes up. With them, I’m my “real shade.”

Conflict is a normal part of any healthy relationship. After all, two people can’t be expected to agree on everything all the time.

◆Take turns talking and listening. Use talking and listening skills to have a conversation about the problem.
◆Restate what you hear. Reflect what the other person says to figure out his or her thought and feelings.
