2 . Chinese material scientists have found the soil on the moon may potentially be able to generate oxygen and fuel, a finding that means more possibilities of humans to use lunar resources to further exploration of the moon and beyond.
The researchers at Nanjing University showed that the lunar sample brought back by China’s Chang’e-5 contains active compounds (化合物) that can change carbon dioxide into oxygen and fuel. Initially, they hoped to design a system that took advantage of lunar soil and solar radiation, the two rich resources on the moon, according to a study published on Thursday in the journal Joule.
After analyzing the Chang’e-5’s lunar soil, the team found the sample contained metal-rich substances, which could work as a catalyst (催化剂) to make oxygen using sunlight and carbon dioxide. The team proposed a strategy using lunar soil to electrolyze water from the moon and the astronauts’ life support system into oxygen and hydrogen. The process was powered by sunlight. The carbon dioxide breathed out by moon inhabitants can be collected and combined with hydrogen to produce the fuel, also catalyzed by the lunar soil, according to the study. The researchers said with this method, no external energy apart from sunlight would be used to produce oxygen and fuel to support life on a moon base.
“We use the environmental resources to minimize rocket payload, and our strategy provides a scenario for a sustainable and affordable living environment for life out of the Earth,” said the paper’s first author Yao Yingfang from Nanjing University, expressing his assumption.
“The challenge lies in the fact that catalytic efficiency of lunar soil is lower than catalysts on the Earth,” said the researchers. They are testing different approaches in order to improve the design. The team is looking for an opportunity to test the system in space with China’s future manned lunar missions.

3 . In the past, music recording was primitive. A recording engineer placed microphones in front of instruments. The producer pressed record and signaled the band to play. There was a human touch to recordings, and this way of recording gave rock music its raw edge. But here we are today. Complex and advanced audio software sits in every recording studio. The higher cost and greater practicality make creating digital music common.
However, the modern recordings aren’t beneficial to a rock record. Let’s not forget, being in a band is laborious. You need like-minded musicians to rehearse for hours on end. Nowadays, this isn’t a necessity.
Programming drums on a computer is as simple as filling cells on a spreadsheet, and there you have it, a drumbeat. Only a few professionals are aware that they aren’t listening to true live drums. Such tech is even accessible on your smartphone. Whether on a train or in a bedroom, you can create a full band track without a live band.
What happened to rock music? With pop and hip hop dominating the charts, it feels like the time for bands is over. Is rock music really dying out? Is it really on its last legs, or are we just not trying hard enough?
Artists, inspired by the great rock bands, seek to put their own spin on this classic genre. The spirit of rock music still remains. One singer mixed soul and rock while one band combined indie rock with elements of techno, both with underlying rock characteristics.
The truth is that fresh rock bands are out there and you just need to dig deeper. A search through online music blogs shows a growing number of new rock bands. While rock bands are now not as popular as before and not receiving mainstream exposure, the flame still burns brightly.

5 . How to Deal with Academic Failure
Experiencing failure in academic settings is inevitable in your journey to study. However, once you get through it, you can bounce back from almost any academic failure.
Adopt the proper mindset
The proper mentality plays a big part in dealing with academic failure.
Consider the troubles of chaotic personal relationships and stress. They are the most common external factor making students' academic performance suffer.
Bounce back
Once you have determined that, you need to develop a plan of action. Try to study at the same times and same places each day, so it becomes a routine. Enlist someone to help you stay accountable to your plan of action.
A.Identify the trouble spots |
B.Analyze extracurricular commitments |
C.Achieving academic goals is vitally important |
D.Instead of judging yourself for past shortcomings |
E.Only by recognizing your problems weren't created overnight |
F.Look at the history of your grades and determine the overall trend |
G.Talk to a friend, family member or teacher about helping you stay on track |

9 . When opening certain mobile apps, users often find disruptive (有干扰性的) open-app advertisements that impact their experience. Open-app advertisements are advertisements that appear in between contents or during transition screens, such as when an app is loading the next page. Some of these advertisements can redirect users to another app if the phone is shaken, causing a lot of frustration for consumers.
These open-app advertisements function as gateways and become more common during online shopping festivals, redirecting users to shopping platforms such as Taobao and JD. Most smartphones have a gyroscope sensor (陀螺仪传感器) to detect shaking, leading to unintentional redirection. Many users not only find it annoying to find themselves on an advertisements page, but also have trouble disabling the gyroscope feature since sometimes their phones lack the choice to do so to avoid this issue.
In response, authorities have introduced detailed regulations on shaking advertisements gateways. A regulation published in December 2022 outlines specific rules for the design of “shake-to-open” advertisements. It says that these advertisements can only be “clicked through” if the phone’s rotation angle exceeds 35 degrees, with an action time longer than three seconds.
Additionally, in February, the Ministry of Industry and Information Technology emphasized that pop-up or open-app advertisements should not disrupt users’ experiences. A regulation introduced in May states that advertisements must include a clear button for users to close them.
Government enforcement of these regulations presents challenges, as the number of apps and developers is great. However, this should not be an excuse for internet platforms to break the rules, as this behavior causes far more harm than good. A survey by the Jiangsu Consumer Council showed that over 90 percent of users strongly dislike open-app advertisements, feeling that their rights are being threatened.
While these advertisements might lead to more clicks, the fact is that the advertisements may harm the credibility of the platforms that the advertisements lead to and weaken the users’ willingness to use the platforms. Platforms can achieve a mutually beneficial (互惠互利) solution only if they respect users’ choices and provide suitable advertisements that users are willing to accept.

10 . Are you an “I person” or an “E person”? These two personality labels in particular are widely discussed online. They are part of a popular personality test called the Myers-Briggs Type Indicator, or MBTI. There are 16 personalities in all, of which “I” and “E” refer to “introverted” and “extroverted”, respectively.
Even if someone is typically quiet, many online discussions suggest that an “I person” can still act outgoing at times. For example, when an introverted person is with a group of introverted friends, they might become more social like an “E” person.
According to psychologists, this idea of temporarily switching personalities is called “masking”. That is hiding your true personality in specific situations. “Human beings want to feel they belong, and they might become people-pleasers to do so,” wrote the MasterClass website.
Thinking on this, I may actually be the kind of person that these people are discussing. Most times, I just wish to make the atmosphere more interesting and exciting and show people that I’m easy to get along with. But deep down, I mostly enjoy being alone and quiet.
Using the MBTI result to identify and describe someone’s personality seems fun. However, I went too far at one time. My sister was excitedly making a day-to-day travel plan when I remembered from an article that a “P person” doesn’t like to make or stick to plans, so I said to her, “You don’t seem like a ‘P person’”. “Why?” she asked back. “Since when do I need to follow what my personality test tells me to do?” It was then that I realized that I’d taken the result too seriously.
The MBTI personality test may show something you don’t know about yourself and can even be a fun ice-breaker question when meeting new friends. And that’s all it is—for fun. Knowing someone’s MBTI result doesn’t mean you really know this person.
