2 . How to Deal with a Colleague who Keeps Challenging Your Views
It can be difficult to develop an environment of teamwork when you continually run up against a colleague who challenges your views.
If a co-worker habitually challenges your ideas in a group discussion in a confrontational manner, don’t engage him or get into an argument. Pause for a moment, look the colleague in the eye.
There’s a time and place for everything, including professional disagreements. If a colleague interrupts you or talks over you in an effort to contradict your point or insert (插入) his own opinion, gently remind him that you still have the floor. If the colleague is challenging something you say before you have a chance to address the point, note that as well.
Agree to respect each other.If a particular colleague has a long history of disagreeing with you, you might be able to anticipate his arguments or objections. Prepare rebuttals to address anything your colleague might throw at you.
A.Hold your ground. |
B.Ask for peace-making. |
C.This will help you support your own arguments. |
D.And ask him in a calm voice to repeat what he said. |
E.Here are the ways to deal with colleagues of this kind. |
F.Just find ways to make peace and communicate with your colleague. |
G.The bottom line is, colleagues are not going to agree with each other all the time. |
3 . Louis Pasteur once said, “Chance favors the prepared mind.” That’s the truth behind the following inventions — the scientists were prepared and were able to see the magic in a mistake.
MauveIn 1856, William Perkin was trying to come up with an artificial medicine, but his experiments produced a thick mess. But the more Perkin looked at it, the more he saw a beautiful color in his mess. Turns out he had made mauve, the first-ever synthetic dye (合成染料), which was far better than any natural dyes: the color was brighter, clearer, and didn’t fade or wash out.
SuperglueThis super-sticky substance was discovered by accident — twice! Chemist Harry Coover had been attempting to make clear plastic gun sights, and in 1942 one method he tested produced an extremely quick bonding adhesive (黏合剂). It was useless for his gun sights, though, and he forgot about it until almost ten years later, when he came across it again while developing heat-resistant parts for airplanes. This time he realised its potential, and the product was put on the market.
PlasticIn 1907, shellac (虫胶) was used in electronics. It was costly, so American chemist Leo Hendrik Baekeland tried to produce an alternative. Instead, his experiments produced a material that could take high temperatures. He later developed it into plastic, and it was soon used in the production of almost everything.
TeflonBack in the 1930s, Young DuPont chemist Roy Plunkett was working to make a new kind of CFC for refrigeration. After storing the gas in certain containers, he opened one to discover that it had changed into a white powder that was extremely sticky and had a very high melting point. Three years later, the substance, which was named Teflon, was patented.

5 . A little brain stimulation at night appears to help people remember what they learned the previous day, a study of 18 severe epilepsy (癫痫) patients has found.
During sleep, brain cells fire in rhythmic patterns. When two brain areas synchronize (同步) their firing patterns, they are able to communicate. During non-rapid eye movement sleep, the hippocampus, found deep in the brain, synchronizes its activity with the prefrontal cortex, which lies just behind the forehead. This helps transform memories from the day into memories that can last a lifetime.
Dr. Itzhak Fried at the University of California and his team gathered 18 epilepsy patients who already had electrodes (电极) in their brains for medical evaluation. This offered the scientists a way to both monitor and change a person’s brain rhythms. They used a “celebrity pet” test in which participants were shown images matching a particular celebrity with a specific animal. The goal was to remember which animal went with which celebrity.
Patients saw the images before going to bed. While sleeping, some of them got tiny electrical stimulation through the wires in their brains. In patients who got the stimulation, rhythms in the two brain areas became more synchronized. And when they woke up they scored higher on the test.
The experiment was based on decades of research done by scientists, including Dr. György Buzsáki, a neuroscientist at New York University. But changing rhythms in healthy peoples’ brains might not improve their memory, he says, because those communication channels are already in perfect condition. The epilepsy patients may have improved because they started out with sleep and memory problems caused by both the disorder and the drugs used to treat it.
Even so, he says, the approach has the potential to help millions of people with damaged memory. And brain rhythms probably play parts in many other problems. “They are not specific to memory. They are doing a lot of other things,” Buzsáki says, like regulating mood and emotion.

7 . After being driven to near extinction, wolves are back in Washington state.
Wolf 32M, called The Old Guy by wolf specialist Ben Maletzke, lived some 12 years as the patriarch (族长) of the Teanaway Pack, kicking off the recovery of wolves in Washington. The pack’s territory was roasted by wildfire in 2014. But wolf 32M and his family remained in existence, bringing the call of the wild back for the first time in a century. These wolves are what Maletzke calls stepping stones in recovery — the animals that could help lead the way to new territory not yet repopulated by wolves.
Wolves spread to new territory to find mates and begin packs of their own. It is this pack dynamic that wildlife biologists are counting on, in time, to urge wolves into areas where they do not presently live. “We just need a couple to pick up and go,” Maletzke says.
All along, the Teanaway pack has stayed mostly out of trouble probably, helped by a lot of range riding (牧区巡逻) intended to help reduce conflicts over wolf recovery by keeping wolves away from cattle. “He is an example of wolves living and doing what they do, even around people,” Maletzke says of wolf 32M.
Story Warren, a student at the University of Montana, was just a girl when she first saw 32M’s tracks in the Teanaway River Valley — an exciting encounter that helped generate a serious interest in wildlife that now fuels her studies. To her, the return of the wolf is about more than the species; it is about recovering something even bigger: hope.
“Growing up in my generation, there is so much bad ecological news, a lot of hopelessness about climate change and loss of biodiversity and extinctions,” Warren says, “To have something as wild as wolves coming back to Washington is very encouraging for me — just to know such an amazing and powerful creature exists.”
