1 . When I first aspired to become a science writer, I imagined each day would be filled with inspiration and creativity. The reality, of course, is far less enjoyable than my fantasies. Researching a story, for example, often involves reading lots of dry and technical papers before I finally strike gold with the information that I seek.
Most professions, I imagine, include challenging but necessary tasks that sap enthusiasm. But a recent paper from Edward Lai at the Hong Kong Polytechnic University and his colleagues may offer us all a way to boost our motivation. It is called the "easy addendum effect", and, as the name suggests, it involves ending each work session with a more pleasant task that will be relatively straightforward to complete.
The strategy was inspired by a phenomenon known as the "peak-end rule", which means we often judge events by the way they finish, rather than the overall experience. In one experiment, Daniel Kahneman and his colleagues asked participants to plunge their hands into water at unpleasantly cold temperatures, the first group simply in 14℃ water for 60 seconds, while the second one were given a further 30 seconds in water at 15℃. Surprisingly, most preferred the second option. It seems their memory of the experiment only focused on the last moments, which was slightly more pleasant in the 90-second set-up.
The research suggests that our impressions of work fall prey to the same preference — and we can use that to our advantage. Lai's team gave participants a series of dull tasks — from flexing their muscles against heavy weights to sorting books into alphabetical order or answering customer complaints. In each case, participants performed the tasks with or without an "easy addendum" attached to the end of the job. Those testing their strength were given a few extra rounds of lighter weights while those answering customer queries with some more straightforward requests.
Much like the ice-bath experiments, there was no logical reason why loading on additional work to an existing task should make it more pleasant overall. But the researchers found that the "easy addendums" significantly reduced the anticipated difficulty and increased participants` satisfaction with their jobs.
Since learning about Lai's research, I have tried applying this strategy to my own work. Writing is still my favourite part of the job, and so this article was a pleasant addendum to an otherwise demanding day of research for another one. By putting these words on the page, I feel far more energised about the work behind me — and readier to enjoy the evening ahead.

2 . Until recently, gravitational waves could have been the stuff of Einstein’s imagination. Before they were detected, these waves in space time existed only in the physicist’s general theory of relativity, as far as scientists knew. Now, researchers are on the hunt for more ways to detect the waves. “The study of gravitational waves is booming,” says astrophysicist Karan Jani of Vanderbilt University in Nashville. “This is just remarkable. No field I can think of in fundamental physics has seen progress this fast.”
Just as light comes in a variety of wavelengths, so do gravitational waves. Different wave lengths point to different types of origins of the universe and require different kinds of detectors. Gravitational waves with wavelengths of a few thousand kilometers—like those detected by the United States, Italy and Japan—come mostly from pairs of black holes 10 or so times the mass of the sun, or from collisions of dense cosmic blocks called neutron stars (中子星). These detectors could also spot waves from certain types of exploding stars and rapidly moving neutron stars.
In contrast, huge waves that span light-years are thought to be created by orbiting pairs of bigger black holes with masses billions of times that of the sun. In June, scientists reported the first strong evidence of these types of waves by turning the entire galaxy (星系) into a detector, watching how the waves make slight changes to the timing of regular blinks from neutron stars throughout the Milky Way.
Physicists now hope to dive into a vast, cosmic ocean of gravitational waves of all sorts of sizes. These waves could reveal new details about the secret lives of exotic objects such as black holes and unknown parts of the universe.
Physicist Jason Hogan of Stanford University thinks there are still a lot of gaps in the coverage of wavelengths. “But it makes sense to cover all the bases. Who knows what else we may find?” he says. The search for capturing the full complement of the universe’s gravitational waves exactly could take observatories out into the moon, to the atomic area and elsewhere.

3 . I used to tell my children that they were smart, because I was impressed by their rapid growth. I remember clearly watching my daughter figure out how to build a Lego house that would stand up on its own, and thinking: Look at this tiny architectural genius.
But decades of research now suggest that we should not tell our children they’re “smart” when they do impressive things. When I first heard it, I felt instinctively annoyed. But after I dug into the research, I was persuaded. It all goes back to something called “growth” mindset (心态), a term developed and popularized by Carol Dweck, a professor of psychology at Stanford. Professor Dweck believes that we can change our abilities through effort and strategy. The alternative to a growth mindset is a “fixed” mindset — the idea that our abilities are inborn and can’t be changed. When we praise our children for being “smart,” based on victories like doing well on a test, we’re unconsciously encouraging them to believe that if they do poorly or make mistakes, they’re not smart.
It’s not just what we say that matters, but how we tolerate our children’s failures. A 2016 study by Dweck showed that parents’ “failure mind-sets” affect their children more than their views on intelligence. In other words, if parents think that failure is shameful, their children are more likely to be afraid of making mistakes. The study concludes that everyone is actually a mixture of fixed and growth mindsets, continually evolving with experience. Whatever we say or don’t say to our kids, the key is to get them more comfortable with failures big or small.
It’s helpful for kids to understand that you make mistakes and learn how they happen. When you chat with them, you can describe what you learned, or how you strategized a solution. “You don’t have to deny you have negative emotional reactions,” Dweck said. “We, as a society, don’t do that enough because we feel embarrassed when we make mistakes.” But if we discuss our missteps more and explain how we overcame them, our children can learn to do the same.

5 . Hiring processes can be thought of as a battle between integrity and dishonesty. You might imagine this is a simple fight between truth-seeking firms and self-promoting candidates, and to a certain extent it is. But companies themselves are prone (有倾向的) to bend reality out of shape in ways that are self-defeating.
Start with the obvious wrongdoers: job applicants. When it comes to writing the resume (简历), they tend to massage (美化) reality into the most appealing shape possible. Everyone beyond a certain level of experience is a transformational leader personally responsible for generating millions income; the world economy would be about 15 times bigger than it actually is if all such claims were true. The average British spends four and a half hours a day watching TV and online videos. But each average job candidate is an enthusiast for public welfare, using their spare time only for worthy purposes, like volunteering in soup kitchens.
But the tendency to stretch the truth infects companies as well as applicants. The typical firm will write a job description that invariably describes the work environment as fast-paced and innovative, and then lays out a set of improbable requirements for the “ideal candidate”, someone who almost by definition does not exist. Sometimes, the requirements include an ability to go back and change the course of history.
Too few firms offer an accurate account of what a position actually involves in their job previews, which are supposed to give prospective employees a genuine sense of the negatives and positives of the job, as well as a clear idea of the company’s corporate culture. One effective strategy is to lay out in text or video, what a typical day in the role would look like.
Such honesty can be its own reward. Research has long suggested that realistic job previews lead to lower turnover and higher employee satisfaction. A paper in 2011 by David Eamest of Towson University and his co-authors concluded that favourable perceptions of the organisation’s honesty are the best explanation for why. So a process designed to uncover the truth about job applicants would run a lot more smoothly if firms were also honest about themselves.

7 . Children’s Acquiring the Principles of Mathematics and Science
It has been pointed out that learning mathematics and science is not so much learning facts as learning ways of thinking. It has also been emphasized that in order to learn science, people often have to change the way they think in ordinary situations. These changes in ways of thinking are often referred to as “conceptual changes”. But how do “conceptual changes” happen? How do children change their ways of thinking as they learn in school?
The psychologist Piaget suggested an interesting hypothesis (假说) relating to the process of cognitive (认知的) change in children. Cognitive change was expected to result from the pupils’ own intellectual activity. When met with a result that challenges their thinking, that is when faced with conflict, pupils realize that they need to think again about their own ways of solving problems, regardless of whether the problem is one in mathematics or in science. He hypothesised that conflict brings about unbalance, and then triggers processes that ultimately produce cognitive changes. For this reason, pupils need to be actively engaged in solving problems that will challenge their current mode of reasoning. However, Piaget also pointed out that young children do not always abandon their ideas in the face of conflicting evidence. They may actually abandon the evidence and keep their theory.
Piaget’s hypothesis about how cognitive change occurs was later translated into an educational approach which is now termed “discovery learning”. Discovery learning initially took what is now considered the “lone learners” route. The role of the teacher was to select situations that challenged the pupils’ reasoning; and the pupils’ peers had no real role in this process. However, it was subsequently proposed that interpersonal conflict, especially with peers, might play an important role in promoting cognitive change. This hypothesis has been investigated in many recent studies of science teaching and learning.
Christine Howe and her colleagues, for example, have compared children’s progress in understanding several types of science concepts when they are given the opportunity to observe relevant events. In one study, Howe compared the progress of 8 to 12-year-old children in understanding what influences motion down a slope. In order to figure out the role of conflict in group work, they created two kinds of groups according to a pre-test: one in which the children had dissimilar views, and a second in which the children had similar views. They found support for the idea that children in the groups with dissimilar views progressed more after their training sessions than those who had been placed in groups with similar views. However, they found no evidence to support the idea that the children worked out their new conceptions during their group discussions, because progress was not actually observed in a post-test immediately after the sessions of group work, but rather in a second test given around four weeks after the group work.

8 . Cancer-fighting genes in elephants could help tackle one of the biggest killers of people, according to research. Despite their large bodies and long lifespans, elephants are much less likely to die from cancer than humans, with death rates of less than 5 percent.
The paradox has puzzled scientists because more cells lead to greater replications (复制), which increases the possibility of the body failing to detect damaged DNA or a faulty cell that can result in tumors(肿瘤). Elephants live for almost as long as humans and weigh up to five tons.
However, a group of British and European scientists say they have taken a big step towards solving Peto’s paradox, named after the British epidemiologist Sir Richard Peto. Elephants, they say, carry a much larger more diverse group of tumor-fighting proteins.
The findings, published last week in the journal Molecular Biology and Evolution, raise hopes that the cancer fighting genes in elephants could be the key to tackling cancer, which kills about 167, 000 Britons yearly. Cells keep dividing throughout an organism’s life, each carrying the risk of producing a tumor. One of the body’s weapons is a gene called p53 known as the “guardian of the genome”, which hunts cells with faulty DNA. It encourages the cell to repair itself or self-destruct, keeping the cell from combining with others and producing tumors.
Humans have two versions of p53 but elephants have 40, said the researchers. Biochemical analysis and computer simulations also showed that an elephant’s p53 genes are structurally slightly different, providing a much larger anti-cancer toolkit. The researchers suspect that while faulty cells might be able to skirt two p53 versions, they cannot combine with other cells as easily in the face of dozens.
The findings will open the way for research on how p53 genes of elephants are activated and on medical treatment for humans.

9 . Researchers at the University of Sussex, Imperial College London and Nanyang Technological University in Singapore have for the first time used game theory (博弈论) to allow robots to assist humans safely and variously.
The research team used adaptive control (自适应控制) and Nash equilibrium (纳什均衡) to program a robot that can understand its human users’ behavior in order to better foresee their movements and respond to them. The researchers believe the breakthrough could make robots help humans do things better in many areas, such as sport training, body recovery or shared driving.
Lead author Dr Yanan Li, Lecturer in Control Engineering at the University of Sussex, said, “It is still very early days in the development of robots and at present, those robots for work are not intuitive enough to work closely and safely with human users. By allowing the robot to identify human users’ behavior and make use of game theory to let the robot react to them in the best way, we have developed a system where robots can work along with humans as humans do.”
To successfully apply game theory to the interaction of a robot and its human users, the researchers had to overcome the problem that the robot cannot know the humans’ intentions. The researchers thus had to develop a method allowing the robot to identify the human partner while safely and efficiently interacting with their motion.
The reactive robotic programming system allows a robot to continuously learn the human users’ control and adapt its own control accordingly. The robot is able to understand the human users’ action and then respond to it and help them to perform tasks successfully with minimal effort.
Professor Etienne Burdet, senior author of the paper, added: “Game theory has had important influences on economics during the last century and lead to several Nobel prizes.”

10 . We are in the midst of a battle for our attention. Our devices have affected our brains and destroyed our collective ability to concentrate. Journalist Johann Hair’s new book, Stolen Focus, has just joined the voice s complaining about the great influence of the digital age. His and other recent books reflect a public perception that our focus is under attack.
Indeed, in out new research, we found some clear concerns. We surveyed a nationally representative sample of 2,093 UK adults in 2021. Half of those surveyed felt their attention ans were shorter than they used to be, compared with a quarter who didn’t. And three quarters of participants agreed we’re living through a time when there’s non-stop competition for our attention between a variety of media channels and information outlets (渠道).
There has long been a worry about the threat to attention brought by new cultural forms, whether that’s social media or the cheap paperback sensation novels of the 19th century. Even as far back as ancient Greece, the philosopher Socrates complained that the written words created “forgetfulness in our souls”. There has always been a tendency to fear the effects that new media and technologies will have on our minds.
The reality is that we simply don’t have long-term studies that tell us whether our attention spans have actually shrunk. What we do know from our study is that people overestimate some of the problems. There’s no such thing as an average attention span. Our ability to focus varies hugely depending on the individual and the task at hand.
It’s also important not to ignore the many benefits that technology brings to our life. Much of the public surveyed recognized these, so while half thought big tech and social media were ruining young people’s attention spans, roughly another half felt that being easily distracted was more to do with people’s personalities than any negative influence that tech ho logy may or may not have. Also, half of the public believed multitasking at work and switching frequently between emails, phone calls, and other tasks can create a more efficient and satisfactory work experience.
