1 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.
But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.
According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.
To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.
“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.
Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.
It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.

3 . As the concept of emotional intelligence (EI) has gone global, we’ve watched professionals fail as they try to improve their emotional intelligence because they either don’t know where to focus their efforts or they haven’t understood how to improve these skills on a practical level. In our work consulting with companies and coaching leaders, we have found that if you’re looking to develop particular EI strengths, it helps to consider areas for improvement others have identified along with the goals you want to achieve and then to actively build habits in those areas rather than simply relying on understanding them conceptually.
The first step is to get a sense of how your self-perception (how you see yourself) differs from your reputation (how others see you). This is especially true for the development of EI because we can be blind to how we express and read the emotional components of our interactions. For example, most of us think that we’re good listeners, but very often that’s really not the case. Without this external reality check, it will be difficult for you to identify the ways that your actions affect your performance. Getting teed back from others can also provide proof of the necessity of shifting our behavior and motivation to do so.
To give you the best sense of where the differences lie between your self-perception and reputation, you should use a 360-degree feedback assessment that takes into account the multiple aspects of EI. The key is to find one to give you feedback, which is focused on development and not on performance assessment. And that can give you a detailed understanding of how other people’s assessments of you differ from your own assessments.
Secondly, when you get your feedback from an assessment, let that inform what you want to improve. But also consider what your goals are. When it comes to cultivating strengths in emotional intelligence, you’re at a huge disadvantage if you’re only interested because others say you should be. Your emotional intelligence is so tied up in your sense of self that being intrinsically (内在的) motivated to make the effort matters more when changing longstanding habits than it does when simply learning a skill.
That means the areas that you choose to actively work on should lie at the intersection of the feedback you’ve gotten and the areas that are most important to your own aspirations (抱负). Understanding the influences of your current EI habits relative to your goals will keep you going over a long period at time as you do the work or strengthening your emotional intelligence.

6 . Women are still underrepresented in top academic positions. One of the possible explanations for this is the increasing importance of obtaining research funding. Women are often less successful in this than men. Psychology researchers Dr. Romy van der Lee and professor Naomi Ellemers investigated whether this difference also occurs at the Netherlands Organisation for Scientific Research (NWO) and examined potential explanations.
The researchers were assigned by NWO to carry out this study as part of the broader evaluation of NWO’s procedures and its gender diversity policy. The aim was to gain more insight into the causes of the differences in awarding rates for male and female applicants for research funding. The analysis addressed an important “talent programme” of NWO, the Veni grant. “Whoever receives this grant has a greater chance of obtaining an important appointment at a university, ” says Naomi Ellemers.
Van der Lee and Ellemers investigated all the applications submitted by male and female researchers over a period of three years: a total of 2823 applications. Under the direction of NWO these applications were assessed by scientific committees consisting of men and women. The results demonstrate that the awarding rates for female applicants (14.9%) are systematically lower than those for male applicants (17.7%). “If we compare the proportion of women among the applicants with the proportion of women among those awarded funding, we see a loss of 4%,” said Ellemers.
The study reveals that women are less positively evaluated for their qualities as researcher than men are, “Interestingly the research proposals of women and men are evaluated equally positively. In other words, the reviewers see no difference in the quality of the proposals that men and women submit,” says Romy van der Lee.
In search for a possible cause for the differences in awarding rates and evaluations, the researchers also investigated the language use in the instructions and forms used to assess the quality of applications. This clearly revealed the occurrence of gendered language. The words that are used to indicate quality are frequently words that were established in previous research as referring mainly to the male gender stereotype (such as challenging and excellent). Romy van der Lee explains: “As a result, it appears that men more easily satisfy the assessment criteria, because these better fit the characteristics stereoty-pically associated with men.”
In response to the results of this research, NWO will devote more attention to the gender awareness of reviewers in its methods and procedures. It will also be investigated which changes to the assessment procedures and criteria can most strongly contribute to more equal chances for men and women to obtain research funding. This will include an examination of the language used by NWO. NWO chair Jos Engelens said, “The research has yielded valuable results and insights. Based on the recommendations made by the researchers we will therefore focus in the coming period on the development of evidence-based measures to reduce the difference in awarding rates.”

8 . What would the world be if there were no hunger? It’s a question that the late ecologist Donella Meadows would ask her students at Dartmouth College back in the 1970s. She set out to create a global movement. The result—an approach known as systems thinking—is now seen as essential in meeting big global challenges.
Systems thinking is crucial to achieving targets such as zero hunger and better nutrition because it requires considering the way in which food is produced, processed, delivered and consumed, and looking at how those things relate with human health, the environment, economics and society. According to systems thinking, changing the food system—or any other network—requires three things to happen. First, researchers need to identify all the players in that system; second, they must work out how they relate to each other; and third, they need to understand and quantify the impact of those relationships on each other and on those outside the system.
Take nutrition for example. The United Nations Food and Agriculture Organization tracked 150 biochemicals in food and various databases, which revealed the relationships between calories, sugar, fat, vitamins and the occurrence of common diseases. But using machine learning and artificial intelligence, network scientists propose that human diets consist of at least 26,000 biochemicals and that the vast majority are not known. This shows that we have some way to travel before achieving the first objective of systems thinking—which, in this example, is to identify more constituent parts of the nutrition system.
A systems approach to creating change is also built on the assumption that everyone in the system has equal power and status. But the food system is not an equal one. There have been calls for a World Food and Nutrition Organization, so that legally binding policies can be applied to all its members. Another way to address power imbalances is for more universities to do what Meadows did and teach students how to think using a systems approach.
A team of researchers has done just that, through the Interdisciplinary Food Systems Teaching and Learning program. Students from disciplines including agriculture, ecology and economics learn together by drawing on their collective expertise in tackling real-world problems, such as how to reduce food waste. Since its launch in 2015, the program has trained more than 1,500 students from 45 university departments.
More researchers, policymakers and representatives from the food industry must learn to look beyond their direct lines of responsibility and embrace a systems approach, as the editors of Nature Food advocate in their launch editorial. Meadows knew that visions alone don’t produce results, but concluded that “we’ll never produce results that we can’t envision”.
