1 . The first person to receive a brain-monitoring device from neurotechnology company Neuralink can control a computer cursor(光标) with his mind, Elon Musk, the firm’s founder, revealed this week. But researchers say that this is not a major feat — and they are concerned about the secrecy around the device’s safety and performance.

Musk announced on 29 January that Neuralink had implanted a brain–computer interface (BCI) into a human for the first time. Neuralink, which is headquartered in Fremont, California, is the third company to start long-term trials in humans.

The Neuralink chip contains 64 flexible polymer threads, providing 1,024 sites for recording brain activity according to the company’s study brochure. That is considerably more than Blackrock Neurotech’s BCIs, the only other single-neuron recording system to have been implanted long-term in humans. So the Neuralink device can improve brain–machine communication.

The company has also produced a surgical robot for inserting its device. But it has not confirmed whether that system was used for the first human implant. Details about the first recipient are also scarce, although Neuralink’s volunteer recruitment brochure says that people with quadriplegia(四肢瘫痪者) stemming from certain conditions “may qualify”.

This week, Musk said on Spaces — an audio component of his social-media platform X — that the volunteer “seems to have made a full recovery, with no ill effects that we are aware of” and “is able to move a mouse around the screen by just thinking”.

To researchers working on implanted neurotechnologies, this achievement is underwhelming. Controlling a computer mouse with one’s thoughts could enable people living with paralysis to regain some independence and functionality. But it is a far cry from Musk’s ambitions for the Neuralink device. “Imagine if Stephen Hawking could communicate faster than a speed typist or auctioneer,” Musk wrote last month on X. “That is the goal.”

However, even more important at this stage, researchers say, is safety — of both the device and the surgery. Sheth says he and other researchers are in the dark about the system’s first application in the clinic.

2 . How many bosses could rely on their employees threatening to quit in mass if they were abruptly forced out? Sam Altman received such a show of support from more than 700 staff after he was fired from Open AI that he was swiftly restored to his position by the board. But this level of loyalty is not typical and may not always be a good thing.

Management experts say staff who are loyal to their employer are inclined to invest more time and effort in their jobs, helping to create an engaged and higher performing workplace. In turn they receive promotions and pay rises. They have a greater sense of belonging and potentially a longer career at the same organisation. But it is not all rosy. People who are too loyal are more likely to take actions that are deemed wrong to keep their jobs and protect their employer, according to a 2021 academic paper. They might overlook wrongdoing and be less likely to expose corruption. Loyalty is sometimes seen as such a force for good that it can be used to justify bad behavior.

Often companies and senior bosses are the real winner a of employee loyalty. Research led by Matthew Stanley at Duke University’s Fuqua School of Business published this year, found that managers were more likely to exploit loyal individuals. Stanley recruited almost 1,400 managers to read about a fictional 29-year-old employee called John, who worked for a company that was trying to keep costs down. They had to decide how willing they would be to ask John to work longer hours and take on more work without more pay. Researchers created various situations including labelling John as loyal versus other traits such as honest and fair. Managers were more willing to ask loyal John to take on the burden of unpaid work.

However, Consultancy Gallup’s latest state of the workplace report showed that half of the 122, 416 employees who took part in a global survey were looking out for new work. “You can’t guarantee anyone will stick around these days,” says a consultant who advises boards. This is particularly true of younger generations. They trust their bosses less and are not as patient when it comes to career progression, seeing little benefit in keeping their heads down and following orders if they do not see results quickly.

3 . Obese people experience discrimination (歧视) in many parts of their lives, and the workplace is no exception. Studies have long shown that obese workers, defined as those with a body-mass index (BMI) of 30 or more, earn significantly less than their slimmer co-workers.

Yet the costs of weight discrimination may be even greater than previously thought. “The overwhelming evidence,” wrote the Institute for employment Studies, “is that it is only women living with obesity who experience the obesity wage penalty (薪资损失).” They were expressing a view that is widely aired in academic papers. To test it, The Economist has analyzed data concerning 23,000 workers from the American Time Use Survey, conducted by the Bureau of Labour Statistics. Our number-processing suggests that, in fact, being obese hurts the earnings of both women and men.

The data we analyzed cover men and women aged between 25 and 54 and in full-time employment. At a general level, it is true that men’s BMIs are unrelated to their wages. But that changes for men with university degrees. For them, obesity is associated with a wage penalty of nearly 8%, even after accounting for the separate effects of age, race, graduate education and marital status.

The conclusion — that well-educated workers in particular are penalized for their weight — holds for both sexes. Moreover, the higher your level of education, the greater the penalty. We found that obese men with a Bachelor’s degree (学士学位) earn 5% less than their thinner colleagues, while those with a Master’s degree earn 14% less. Obese women, it is true, still have it worse: for them, the equivalent figures are 12% and 19%, respectively (分别地).

Your line of work makes a difference, too. When we dealt with the numbers for individual occupations and industries, we found the greatest differences in high-skilled jobs. Obese workers in health care, for example, make 11% less than their slimmer colleagues; those in management roles make roughly 9% less, on average. In sectors such as construction and agriculture, meanwhile, obesity is actually associated with higher wages.

These results suggest that the total costs of wage discrimination borne by overweight workers in America are greater than expected. Now, it’s time for our governments to take it seriously.

5 . Older people traditionally struggle with new tech, but it doesn’t have to be this way. With the right design, even the most unwilling user can obtain the benefits.

A lack of understanding of technology and its benefits, along with difficulty in using hi-tech products, such as a smartphone or computer, leads to the result that many seniors hesitate to migrate from the old to the new. This is a mistake.

Older people themselves must consider whether they want to embrace new technology, or let the benefits pass them by. Technology, often in the form of social media, has enabled seniors to meet new friends, keep in touch with old ones and learn new skills.

The reasons why some older people adopt new technology are likely to be twofold: they’re forced to do so and they want to make their lives easier. These reasons are important for anyone who realizes seniors need to be convinced to engage with technology to consider.

Adopting new technology is often imperative for modern people to do, yet some elderly still insist, “I have managed before without technology. Why do I have to use it now?”

Seniors often become frustrated with technology. “It’s not working, ” is a complaint co-author Lucia heard many times from her late father, especially when it came to his cell phone-and he used technology well, for the most part. Often, the problem was that he was unable to use the small keypad( 键盘) on his phone or read the letter size of the words in text messages he received.

One issue that needs to be addressed is the design of technology. Seniors want web pages to be simple and clear, and navigation easy. One study from 2005 shows that many seniors like a website to be user-friendly with a simple interface (界面).

“A simpler and more uniformly designed internet would help to break down the psychological barriers outlined, ”it states. While that study was carried out years ago, this problem with web design still stands.

7 . Film Puts Justifiable Defense in Spotlight

The film, Article 20, directed by Zhang Yimou, draws its name from Article 20 of the Criminal Law, which focuses on the sometimes controversial legal concept of justifiable defense. Drawing inspiration from real-life cases of justifiable defense, the film gained widespread attention and struck a chord with the public during the Spring Festival holiday. The movie calls for a de tailed interpretation of legal terms and urges against compromising on unlawful conduct.

According to the Criminal Law, when a person, faced with an unlawful attack, takes action to protect his or her own rights or interests or those of others, and the attacker is thereby harmed, the defender will be considered to have acted in justifiable defense and will not bear criminal responsibility. For some time, justifiable defense has been regarded as a “dormant clause” (沉寂条款), due to the influence of misconceptions, such as “whoever is injured or killed is right”.

But the true meaning of the law should be to increase the responsibility for wrongdoers, rather than burdening good people. Recent cases have shown that, for ordinary citizens, justifiable defense is no longer a pipe dream. A high-profile case in Kunshan, Jiangsu province, in 2018 served as a wake-up call and caught the attention of authorities regarding such cases. In that case, a traffic argument led to a motorist who took a knife with him confronting another man. The motorist was killed, and police and judges determined that the defender’s actions constituted justifiable defense. Since then, the justifiable defense clause has been applied in several places across the nation. The concern over justifiable defense reflects the public’s demand for fairness, justice, security and rule of law.

Luo Xiang, a renowned professor of criminal law at China University of Political Science and Law, said in a recent comment about the film Article 20 that the public and judges should avoid taking a “godlike” perspective. Instead, they should consider the situation in which the defender was involved, empathize with the defender’s position, and stop themselves from making excessive demands on the defender, Luo said.

9 . The rise of body neutrality You define (定义) beauty yourself. You are more than a number in measurement. Love yourself the way you are. Body positive messages like theses seem to be everywhere from social media to TV advertisements.

Body positivity’s aim to boost acceptance and appreciation of a variety of body types and sizes may explain why it has such a broad appeal. While some find the body positivity movement to be helpful, others have begun calling the movement toxic and suggesting it may be time to move on from this way of thinking.

More recently, people have voiced concerns. Some feel that the focus on loving your looks actually strengthens society’s stress on appearance over other values. Much body positivity content in advertisements may bring a stereotype (刻板印象) to viewers because it does little to challenge the hidden assumption that people are valued mainly for their appearance. Therefore, the movement still encourages people to be graceful and engage in beauty practices from head to toe. And if you fail to be body positive, it’s you that are at fault.

Many are now moving away from the body positivity movement and the pressures that come from it entirely, and instead are getting behind the body neutrality (中立) movement. Instead of focusing on physical appearance, body neutrality is a profound idea that we can exist without having to think too much about our bodies.

We are all more than just our bodies. We are complicated beings with a range of emotions and feelings about our bodies. And because body neutrality de-emphasizes (不强调) the focus on appearance, it motivates us to better acknowledge all the things our bodies are able to do. Being grateful for being able to take up your hobbies and appreciating your body for what it’s capable of doing are both examples of body neutrality.

Body neutrality can be beneficial to us. It is associated with the positive body image and mental well-being. The good news is that there are many ways you can develop body neutrality, including writing-based treatment, yoga and spending time in nature.

10 . The next time you’re at an airport or hotel, you might notice a traveling group that consists of young kids, parents, and grandparents vacationing together.     1    But more and more families tend to bring multiple generations with them.

    2    In larger groups, for example, child-care responsibilities can be shared across family members, allowing parents to take a break. But the real value of these trips might be how they give relatives an opportunity to freshen their perception of the people they’ve known for perhaps their entire life. Travel can take us out of our familiar contexts and offer people a chance to see one another differently.

The shift toward multi-generational travel has a few explanations. For one, grandparents today stay healthy later in life, allowing them more energy for travel.     3    Plus, the average U.S. household has become more multi-generational. Americans are not just traveling with grandparents in order to spend time with them, they are traveling with them because they are more likely to live with them in the first place.     4    Americans are taking fewer vacation days than they did in the 1970s. They might want to make the most of that time by including as many people as possible.

Whatever the reason for its popularity, a multi-generational trip can be a rare time when younger and older generations can glimpse the complex people they have each become. Away from the family home, older generations get to see their adult children as responsible parents. Kids get to see their grandparents encounter a new environment.     5
