1 . A new study by scientists at Utrecht University concludes that about half of global wastewater is treated, rather than the previous estimate of 20%. Despite this promising finding, the authors warn that treatment rates in developing countries are still very low.

Humans and factories produce vast quantities of wastewater per day. If not properly collected and treated, wastewater may severely threaten human health and pollute the environment.

The authors use national statistics to estimate volumes of wastewater production, collection, treatment and reuse. “Globally, about 359 billion cubic metres of wastewater is produced each year, equivalent to 144 million Olympic-sized swimming pools,” says Edward Jones, PhD researcher at Utrecht University. “About 48 percent of that water is currently released untreated. This is much lower than the frequently announced figure of 80%.”

While the results show a more optimistic outlook, the authors stress that many challenges still exist. “We see that particularly in the developing world, where most of the future population growth will likely occur, treatment rates are falling behind,” Jones explains. “In these countries, wastewater production is likely to rise at a faster pace than the current development of collection and treatment basic facilities. This poses serious threats to both human health and the environment.”

The main problem, especially in the developing world, is the lack of financial resources to build basic facilities to collect and treat wastewater. This is particularly the case for advanced treatment technologies, which can be extremely expensive. However, the authors highlight potential opportunities for creative reuse of wastewater streams that could help to finance improved wastewater treatment practices.

“The most obvious reuse of treated wastewater is to increase freshwater water supplies,” Jones states. Treated wastewater reuse is already an important source of irrigation water in many dry countries. However, only 11% of the wastewater produced globally is currently being reused, which shows large opportunities for expansion.

“But freshwater increasing is not the only opportunity,” says Jones. “Wastewater also has large potential as a source of nutrients and energy. Recognition of wastewater as a resource, opposed to as ‘waste’, will be the key to driving improved treatment going forward.”

However, the authors stress the importance of proper monitoring of wastewater treatment factories, accompanied by strong legislation (法律) and regulations, to ensure that the reuse of wastewater is safe. The authors also acknowledge public acceptance as another key barrier towards increasing wastewater reuse.

2 . How to Deal with FOMO in Your Life

FOMO, or “fear of missing out,” is becoming increasingly common and can cause significant stress in your life. It applies to anything from a party to a promotion at work and affects just about anyone. It always involves a sense of helplessness that you are missing out on something big.

    1     However, while it has been around for centuries, it has only been studied during the past few decades, beginning with a 1996 research paper by Dr. Dan Herman.

With social media becoming popular, FOMO has become more obvious. As more research on FOMO is conducted, we are getting a clearer picture of how it affects us.     2     Aside from feelings of unhappiness, fear of missing out can lead to greater involvement in unhealthy behaviors. For example, the same study in Computers and Human Behavior found that FOMO was linked to distracted driving, which in some cases could be deadly.

Moreover, one study found that the fear of missing out was linked to a greater smartphone and social media usage.     3     They create a platform where things, events, and even happiness seem to be in competition, which may lead you to wonder what you are lacking. Greater engagement with social media can make us feel worse about ourselves and our lives, not better.

    4     Feelings of loneliness are our brain’s way of telling us that we want to connect with others and increase our sense of belonging. Unfortunately, social media engagement is not the way to accomplish this—you might be running from one bad situation right into an even worse one.

Rather than trying to connect more with people on social media, why not arrange to meet up with someone in person? Making plans with a good friend, or doing anything social that gets you out with friends can be a nice change of pace.     5    

The use of the internet in academic contexts is on the rise. However, its role in learning     1     (debate) by teachers and students. For many teachers who did not grow up with this technology, its effects seem alarming and     2     (potential) harmful. But the internet has had a major positive impact on the world of education. The future of teaching lies in the possibilities the internet opens up for communication, research, and interactivity. Students value the flexibility and accessibility     3     (offer) by digital education. Educators should welcome these advantages.

7 . Mindfulness—in basic terms, the practice of being “present” in the moment and paying attention to one’s own thoughts and feelings—has seen something of a boom over the last few years. While it certainly has its benefits, some argue that it encourages blind acceptance of the status quo, taking us so far into ourselves that we forget the rest of the world. In a new preprint on PsyArxiv, Michael Poulin and colleagues from New York’s University at Buffalo also find that mindfulness can decrease prosocial behaviours (亲社会行为).

The first study was designed to look at the impact of mindfulness on prosocial activity, and in particular, whether this depends on a person’s “self-construal”. In short, if someone has an independent self-construal they see the self as separate from others, rather than thinking more collectively and conceptualizing themselves as part of a wider group.

Participants were randomly assigned to one of two conditions, one oriented around mindfulness meditation, and the other focusing on a control meditation in the form of mind wandering. Those in the mindfulness condition listened to a tape designed to inspire mindfulness through mindful breathing, while those in the mind wandering condition were instructed to “let your mind wander and think freely”.

After listening to the tapes, participants read about a local poverty and homelessness charity, before being asked whether or not they wanted to stuff envelopes in support of the organisation. Participants who decided to take part were left to do so for as long as they wanted. The team also measured participants’ self-construal by asking them to indicate how much they identified with friends, family, and wider groups compared to how much they thought of themselves as independent.

Most participants (84%) stuffed at least some envelopes after the task. People who participated in the mindfulness meditation stuffed 15% more envelopes than those who did the control mediation—if they had an interdependent self-construal. But for those with independent self-construals, mindfulness decreased the number of envelopes stuffed by 15%.

As the second study took place online, participants were not asked to stuff envelopes, but instead to sign up (or not) to chat online with alumni donors to request financial support for the same charity. And similar to the results of the first study, those in the interdependent condition saw an increased likelihood of volunteering after the mindfulness task, while those with independent self-construal were less likely to volunteer after listening to the mindfulness exercise.

Mindfulness has often been positioned as a panacea (灵丹妙药), not only for anxiety or other mental health conditions but in other areas, too: productivity, creativity, personal relationships, and particular traits or habits. Rather than treating it as a wholesale good, however, it may be better to understand when mindfulness might be truly beneficial—and, importantly, for whom.

8 . The “laugh out loud” face is officially the world’s most popular emoji, according to researchers from Adobe (ADBE) who surveyed 7,000 users across the United States, the United Kingdom, Germany, France, Japan, Australia, and South Korea.

The “thumbs up” emoji came in second, followed by the “red heart” emoji. The flirtatious “wink and kiss” and “sad face with a tear” emojis respectively rounded out the top five.

The software maker on Thursday released the findings from its 2021 Global Emoji Trend Report ahead of World Emoji Day on Saturday.

Adobe’s latest Emoji Trend report also examined the three most misunderstood emojis in the world. The “eggplant” symbol edged out the “peach” and the “clown” emojis respectively as the most confusing for users.

The vast majority of emoji users (90%) believe the modern —day hieroglyphs make it easier for them to express themselves. Eighty — nine percent of respondents said emojis simplify communicating across language barriers. And 67% said they think people who use emojis are friendlier, funnier and cooler than those who don’t. A slight majority of respondents said they are more comfortable expressing emotions through emojis than talking on the phone or in —person. More than half of global emoji users (55%) said using emojis in communications has positively impacted their mental health. Seventy — six percent of those surveyed said emojis are an important communication tool for creating unity, respect and understanding. And 88% said they feel more empathetic toward people who use emojis.
