1 . Having thousands of photographs, songs, and films available at our fingertips would have seemed amazing just a few decades ago.
The materials phones and computers are made of can decay (腐烂) over time, impacting the data that they store.
Licensing rather than purchasing content is an example of how our behavior towards digital content has changed. Another example is that we take far more pictures than people did in the past.
So, what can we do? Technology writer Jack Schofield said that “data doesn’t exist unless you have at least two copies of it”.
A.This adds to the challenge of keeping our data safe. |
B.But how long will these files last for and be available? |
C.Storing information in the cloud can also help preserve it. |
D.Images can still be seen in discolored physical photographs. |
E.Storing your uploads on a cloud service can present problems as well. |
F.However, it’s common presently thanks to technological advancements. |
G.So it’s important that we keep backup copies of what is important to us. |
2 . The first transplant surgery to combine a mechanical (机械的) heart pump as well as a gene-edited pig kidney has recently been completed at NYU Langone Health.
The subject, 54-year-old Lisa Pisano of New Jersey, had heart failure and end-stage kidney disease. But she couldn’t have a standard heart or kidney transplant because of certain medical conditions and an overall lack of donor organs in the US. According to the Organ Transplantation Network, roughly 27,000 kidneys were transplanted last year, but nearly 89,000 people were on the waiting list for those organs.
Pisano got the heart pump on April 4 and then, on April 12, received a pig kidney, which was gene-edited to help keep the human body from recognizing the animal’s organ as foreign and rejecting it. “The editing process was to disrupt a gene responsible for the production of a sugar found on the surface of animal cells called alpha-gal, which can be recognized by human antibodies (抗体) and attacked,” said Dr. Robert Montgomery, director of the NYU Langone Transplant Institute, who led the surgery.
Montgomery noted that the gene edits used in the pig in this case are much simpler than those used in other transplants. “We’re going to have an opportunity to really address the problem that we’re trying to address, which is the scarcity of organs, and the more complex the gene edits, the less likely it is that you’ll be able to produce those edits into a pig group. You would have to clone every pig for each organ. That is not something that can be easily achieved. So, we feel like less is more in this case.”
“Pisano has a long way to go and we are watching out for rejections,” he said, “but her kidney is functioning beautifully, and her heart is in much better shape. What previously existed in science fiction is now a reality.” Doctors expect that she might be discharged within a month.

3 . You might know what to do if a human needs first aid, but what if your dog gets a bite or your cat eats something poisonous? Dr. Liam Donaldson, clinical director at Greencross Vet (兽医) Hospital at the University of Melbourne, says it’s important that pet owners understand basic first aid. Here, he shares his tips for dealing with common accidents and injuries.
Cuts & woundsYou don’t need to worry about disinfecting the injury site, but you do need to stop the bleeding, says Dr. Donaldson. “If there’s uncontrollable bleeding, apply pressure — even if it’s just using a T-shirt. Once you have applied pressure to reduce bleeding, take your pet immediately to a vet for assessment.” he advises.
Snake bitesSnakes have very small teeth, so their bite marks can be difficult to spot — and you might not see the bite happen. But if your pet shows signs of snake bite poisoning — sudden weakness and collapse, dilated pupils, vomiting, paralysis and shaking or twitching of muscles — get them to a vet without delay.
Tick bitesIt’s a good idea to have a pair of tick-removal tweezers (镊子) on hand in case you need to remove a tick from your pet. “There’s often a lot of concern about whether you have to get all of the tick or not, but as long as you get the body of the tick off, generally the head will just remove itself over time,” says Dr. Donaldson. He recommends keeping the tick so that if your pet becomes ill, your vet can identify whether they were bitten by a paralysis tick (the type that can be deadly).
PoisoningCats eating ivy and dogs eating sago palm or macadamia nuts are some of the most common poisonings Dr. Donaldson sees. “If it’s a macadamia nut, I would just keep a very close eye on them. If they start to show any gastrointestinal signs — if they go off their food, if they become sore in any of their legs — get them checked over by a vet,” he says. “If it was lilies or sago palm, I would recommend getting them to a vet, even if they’re not showing signs of illness, just because that can typically be life-threatening.”

9 . After a heavy snowstorm, I ran outside excitedly to build a snowman. No matter how I rolled my snowball, it refused to grow. After resting for a while, I restarted the job. Then I noticed I had an audience-a prim-looking (古板的) couple with obvious disapproval. My face turned red as I tried to answer their unspoken question: Don’t you have anything better to do?
An adult playing by herself seems strange, but’ maybe it shouldn’t. New research suggests that modern adults have ignored their play instinct (本能). Most animals stop playing as adults. However, there are a handful of animals that never stop.
One possibility is’ that adult play is important and beneficial, -a theory supported by a study. Researcher Camilla Cenni from the University of Lethbridge left some puzzle boxes for some monkeys to solve. To get the food inside, they had to drop a rock into the container. The monkeys that previously had dropped rocks for fun were more likely to solve the puzzle. This finding also suggests somewhere in our evolutionary history—a playful human invented stone tools. Even today, the urge to play accounts for some of humans’ greatest inventions. Adult play is also about preparing for the unexpected. And biologists found its most important function is improving relationships and helping individuals get along.
Adult play promotes inclusivity, cooperation and creativity—all qualities that we humans could use. Unfortunately, social norms hold back our urge to let loose. “Generally speaking, we like to do the things that are necessary for our survival,” says Peter Gray, a play researcher at Boston University, Humans took one giant step away from fun when we started planting crops. Plowing (耕) fields is hard and boring. Then we invented factories and lost sight of play.”
With threats like climate change, it’s easy to get into seriousness. But we should understand the value of encouraging adult play. The next time I’m caught playing. I know what to say, “I’m playing for the benefit of all humankind. You’ re welcome.”
