1 . These days, there’s barely a world leader who doesn’t talk up science. For example, the India’s Prime Minister was the main performer at the annual Indian Science Congress, held in Nagpur, where he encouraged the nation’s researchers to do the science needed to make India self-reliant.
The message to researchers is crystal clear: leaders see science as essential to national prosperity, well-being and, of course, competitiveness. So, is research fit for the challenge of advancing, refining or critiquing these goals? Not exactly. And it won’t be until there is fundamental reform to the gateway to a research career: PhD training.
As Nature and other publications have frequently reported, PhD training worldwide has been in trouble for some time. Students’ stipends (生活津贴) are not enough in most countries, creating a cost-of-living crisis. Early-career researchers constantly report concerns about a constant lack of support and poor-quality supervision, with senior researchers rarely trained in mentorship (指导).
Furthermore, PhD candidates are inadequately prepared for the cross-disciplinary working and large teams that characterize cutting-edge science today. This is especially true for careers outside academic research, where the overwhelming majority of PhD candidates will be heading.
It is not all bad. Universities in a small number of high-income countries have reformed, or are reforming, PhD assessment. But in most places, and especially in low- and middle-income countries, a candidate’s work is still evaluated using a single-authored paper. In many countries, candidates must publish in a journal before they get a PhD, something that critics say could fuel profitable publishing.
The system’s strains have become more obvious because the number of people doing PhD training has been rising sharply. According to the 2022 book Towards a Global Core Value System in Doctoral Education, the number of PhDs awarded in India increased from 17,850 in 2004 to 25,095 in 2016; US figures climbed from 48,500 to 69,525 over the same period. If researchers are to meet society’s expectations, their training and mentoring must escape the nineteenth century.

How to Enhance Children’s Attention Span
In a world of increased multitasking and smart devices that constantly compete for our attention, it has become harder to keep children on task during studying or house hold activities. Part of this is environmental, put part of it is also a lack of training that is taking place. Being attentive is a skill, rarely an innate talent, and must be cultivated in children for them to succeed.
Eliminating environmental distractions’ can be a smart way to, improve a child’s attention. It’s important to remember that many things in a child’s environment can draw a child’s attention span away from the task or lesson at hand, including surrounding noises, visual messes and internal distractions. Providing an environment that is as free of distractions as possible can dramatically Improve a child’s attention because it means there are fewer things around for the child’s attention span to be divided between. This is also why it’s a good idea to do studying in an area which is not usually used for other activities, such as in the sitting room.
Not being prepared for a lesson also serves as a distraction because it needs a five or ten minutes to gather the necessary materials. Help keep your child organized and make sure all necessary study materials are close at hand before it’s time to start a lesson to avoid a wild goose chase that will break up your child’s attention before the lesson has even begun.
Several scientific studies have linked a child’s decreased attention span to increased time in front of screened devices such as tablets and television, so parents should make efforts to limit over-stimulation caused by these devices to leisure time and keep them away from studying activities. This isn’t to say that children should avoid the use of smart devices, televisions, or video games indefinitely. After all, these outlets provide much-needed relaxation to children and can even help to improve their hand-eye coordination. I strongly suggest that parents should make sure that screen-time is a privilege (特权) , not a right. That is to say, use screen-time as a reward.

6 . A new study published in the Journal of Marriage and Family claims that all that time you spend parenting just doesn’t matter. But it’s a claim that, despite the enthusiastic and widespread coverage by the media, does not hold water.
The research suggests that child outcomes (including behavior problems, emotional problems, and academic performance) are barely connected with the time that parents spend with their children. The researchers examined the time diaries of 1,600 children, looking at parenting time and outcomes when the kids were aged 3 to 11 in 1997, and again in 2002, when they were between 8 and 16. (A time diary is a detailed report of all activities you carry out in a day. )
This research largely reflects the failure of the authors to correctly measure parental input. It just looked at time diaries from two particular days-one a weekday and the other a weekend day.
Trying to get a sense of the time you spend parenting from a single day’s diary is a bit like trying to measure your income from a single day. If yesterday was payday, you looked rich, but if it’s not, you would be reported as poor. You get a clearer picture only by looking at your income — or your parenting time—over a more meaningful period.
What you did yesterday should not be taken as representative of what you did last year, This is why most high-quality studies of parenting time focus instead on how often parents read to their children, play with them or help their with homework over a period of a month or longer — long enough to represent their different approaches to parenting.
As an exhausted parent who doesn’t get enough time to work out, and who hasn’t seen a movie for months, I understand why so many of us might seize on studies suggesting that we should take more time for ourselves. Perhaps we should. But I agree with Ariel Kalil, a developmental psychologist, on the suggestion “that when parents spend high-quality time with their children, their children are more likely to succeed.”

8 . When Lenore Skenazy let her 9-year-old son take the New York subway home by himself 10 years ago, you would have thought that she’d carried out a crime. Now Skenazy started the movement Free Range (放养的) Kids to bring up safe and independent children. Just this month, Utah became a free range state, changing its law to protect parents from being charged with neglect (疏忽)for letting their kids walk alone, or wait in a car for an adult.
Skenazy argues that the risks of giving children some freedom are exaggerated (夸大). Skenazy’s mother used to send her outside at 5 to walk to school. That was just normal back then. And suddenly we hear stories about parents getting punished for letting their 10-year-old son play outside.
We get so used to not knowing our neighbors, not letting our kids walk to school, or play outside, that nowadays, the kids are either in a car or in the backyard, and they don’t get to know the neighborhood. In fact, the world has become safer. We have the technologies to keep track of almost everything our kids do. And so you think you must control them, and you think your child is something that has to be tracked like a package.
The famous case for many parents was the Etan Patz case in New York in 1979. Patz’s parents gave him permission for the first time to walk to the bus stop nearby. He was killed. The story is so terrible that we remember it two generations later. And we don’t allow our kids to walk alone because of one terrible thing that happened 39 years ago. But we don’t say, “I want to drive you to the dentist, but what if we get in a car accident? Think of those people who died in a car accident 39 years ago. I don’t want to be like them. No, we’re not going.” And we recognize that it would be funny to think that way.

9 . Adults understand what it feels like to be flooded with objects. Why do we often assume that more is more when it comes to kids and their belongings? The good news is that I can help my own kids learn earlier than I did how to live more with less.
I found the pre-holidays a good time to encourage young children to donate less-used things, and it worked. Because of our efforts, our daughter Georgia did decide to donate a large bag of toys to a little girl whose mother was unable to pay for her holiday due to illness. She chose to sell a few larger objects that were less often used when we promised to put the money into her school fund (基金) (our kindergarten daughter is serious about becoming a doctor).
For weeks, I’ve been thinking of bigger, deeper questions: How do we make it a habit for them? And how do we train ourselves to help them live with, need, and use less? Yesterday, I sat with my son, Shepherd, determined to test my own theory on this. I decided to play with him with only one toy for as long as it would keep his interest. I expected that one toy would keep his attention for about five minutes, ten minutes, max. I chose a red rubber ball—simple, universally available. We passed it, he tried to put it in his mouth, he tried bouncing it, rolling it, sitting on it, throwing it. It was totally, completely enough for him. Before I knew it an hour had passed and it was time to move on to lunch.
We both became absorbed in the simplicity of playing together. He had my full attention and I had his. My little experiment to find joy in a single object worked for both of us.

10 . The weather in Texas may have cooled since the recent extreme heat, but the temperature will be high at the State Board of Education meeting in Austin this month as officials debate how climate change is taught in Texas schools.
Pat Hardy, who agrees with the views of the energy department, is resisting proposed changes to science standards for pre-teen pupils. These would emphasize the significance of human activity in recent climate change and encourage discussion of reduction measures.
Most scientists and experts sharply argue against Hardy’s views. “They casually view the career work of scholars and scientists as just another misguided opinion,” says Dan Quinn, senior communications strategist at the Texas Freedom Network, a non-profit group that monitors public education. Such debates reflect fierce discussions across the US and around the world, as researchers, policymakers, teachers and students step up demands for a greater focus on teaching about the facts of climate change in schools.
A study, looking at how state public schools across the country address climate change in science classes, gave barely half of US states a grade B+ or higher. Among the 10 worst performers were some of the most populous states, including Texas, which was given the lowest grade (F) and has a huge influence because its textbooks are widely sold elsewhere.
Glenn Branch, the center’s deputy director, cautions that setting state-level science standards is only one limited norm in a country that decentralizes (使分权) decisions to local school boards. Even if a state is considered a high performer in its science standards, “that does not mean it will be taught”, he says.
Branch points out that, even if a growing number of official guidelines and textbooks reflect scientific consensus (共识) on climate change, unofficial educational materials that convey more biased (带有偏见的) perspectives are being distributed to teachers. They include materials sponsored by libertarian think-tanks (智库) and energy industry associations.

| C．To indicate the atmosphere at the board meeting. | D．To draw the public’s attention to energy shortages. |
| A．Hardy overstates the existing panic. | B．Hardy denies the value of scientific work. |
| C．Hardy shows no concern for pre-teens. | D．Hardy expresses self-contradictory views |
| A．The standards call for regular revision. | B．The standards cater to local needs. |
| C．The standards have limited influence. | D．The standards require urgent application. |
