“REMOVE from friends.”
This is no ordinary button. One click and I have the power to erase a person from my life.
In late fall, I had around 400 friends on Facebook. Today, I have 134.
Click. Make that 133.
When Facebook first entered my life in 2005, I panicked（恐慌、担心） that my friend count was too low. If I wasn’t properly connected, how would anyone see my clever quote(引语)? Who would wish me a happy birthday? I accepted and sent out friend requests without a second thought and soon accumulated 391 friends.
There is an appeal to being able to communicate with someone or just “thumbs(拨动手指) up” a photo rather than make real conversation.
“It’s comforting and it’s easy,” said Larry Rosen, a psychology professor at California State University, who studies the way people communicate online.” There’s a sense of belonging in it. It’s a sense of community in a generation where community has sort of (有点)disappeared.”
However, I don’t talk to half of these people in the online community. There are some I would avoid if I met them on the street.
Click. 132.
I decided to rid my account of any “friend” that…well, wasn’t. Sound easy? You try it.
Look at who you’re dealing with: family, friends, classmates, crushes(爱恋的对象), acquaintances…
With every click of the “Remove from friends” button, you risk burning a bridge, losing a contact and missing an opportunity. So every time I go to click the button, my heart hurts.
However, I’m not the only one who has experienced a Faceboook friend refreshing. The New Oxford American Dictionary announces its “Word of the Year” each year, and last year, “unfriend” made the cut (入围) (though I’ll still stick with “defriend”).
When I started my mission(任务), a few friends joined. Most were surprised by how easily they could cut hundreds of connections without thinking twice.
“Oh my God, I defriended like 600 people today. I feel so good!” my friend Sarah messaged.
Dana, a close friend from high school, and I battled it out to see who could get our counts lower. She wins at 123.
To some, it’s poor “netiquette(网络礼仪)” to defriend. But to me, it’s the stage of life when we hold onto the people who count, the people who impact you.

Every electronic gadget (小玩意) needs good memory. A music player stores songs, albums and playlists. A computer holds schoolwork and programs and remembers how far a player has advanced in his or her favorite game. Mobile phones store names, numbers and hundreds of texts.

Now, scientists in California say they have come up with a way to turn a living cell into a memory device.

It can store only one tiny bit of information, but it’s a start. In the future, a cell-based gadget might travel through the body and record measurements. The benefit to human health could be big: the right tool, for example, might record the earliest signs of disease.

Doctors, scientists and other curious people want to know what is happening inside the body, even at levels that can’t be seen by the naked eye. So far, there is no device small enough to travel through the bloodstream.

If normal machines won’t do the trick, perhaps biology will. Scientists who work in the field of synthetic (合成的) biology are trying to find ways to turn living things into human tools. In the case of the new memory device, bioengineers from Stanford University used the genetic material inside living cells to record information.

This genetic material consists of DNA. Found in nearly every cell, DNA carries all of the information that keeps a living thing alive.

In the new experiment, the researchers turned DNA from bacteria(细菌) into a switch. They “flip (翻转)” a small section of DNA. Then, using the same procedure (过程) , the scientists flip the section again—returning it into its normal structure.

Using these DNA switches, “We can write and erase DNA in a living cell,” bioengineer, Jerome Bonnet, explained to Science News.

It might take years before his team or others identity whether a DNA-based memory device might be practical. Right now, it takes one hour to complete a flip. That is far too long to be useful. Plus, a flipped section has a very small little memory—less than what a computer uses to remember a single letter.

 “This was an important proof that it was doable,” Bonnet told Science News. “Now we want to build a more complex system, something that other people can use.”
