1 . Success Requires “Ample Doses of Pain”

Jensen Huang, CEO of Nvidia, has a simple message for young people who want to achieve greatness: No pain, no gain. That was essentially his message for students at his alma mater, Stanford University, where he made a speech at the Stanford Institute for Economic Policy Research.

“Greatness is not intelligence.     1     And character isn’t formed out of smart people; it’s formed out of people who suffered,” Huang said in response to a question about how students can maximize their shot at being successful.

    2     In 1993, he co-founded computer chip company Nvidia, where he’s served as CEO for more than three decades. The company’s success turned Huang into a billionaire. Now, with Nvidia’s chips in high demand for building AI software, it’s become one of the world’s most valuable companies with a valuation worth of $2 trillion.

“One of my great advantages is that I have very low expectations,” Huang said, noting that most Stanford graduates have very high expectations as a result of having an elite education. Often people with very high expectations have very low resilience because they are not accustomed to, or prepared for, failure. “     3     I don’t know how to teach it to you except for I hope suffering happens to you,” he said. Psychologists also tend to agree that resilient people are more likely to have the strength and confidence to handle challenges and bounce back from failure. Huang certainly had to struggle in his company’s early days.

“To this day I use the phrase ‘pain and suffering’ inside our company with great joy,” Huang told the Stanford students. “    4     You want greatness out of it.”

2 . Monarch Butterflies Listed as Endangered

The monarch butterfly, known for its legendary migration from Mexico to Canada, is now at great risk of extinction. According to the International Union for Conservation of Nature, the population of this orange-and-black insect has shrunk between 23% and 72% over the past 10 years. IUCN has labeled it as being endangered after having added it to its Red List of Threatened Species.

    1    . In order to make space for agriculture and urban development, people have been illegally cutting down trees. As a result, the massive forested areas that had previously sheltered the butterflies during winter have now been destroyed.

Another factor at play is the use of herbicides (除草剂) in agricultural fields.     2    . Just before leaving their overwintering grounds, females lay eggs on milkweed plants. But now milkweed is disappearing, and monarch caterpillars are losing their host plants.

Climate change has also taken a heavy toll on the species.     3    . What’s worse, severe weather conditions such as hurricanes and storms are proving to be disastrous for the already vulnerable butterflies.

Monarch experts are calling for the public’s help in the fight to save the species. “Few species inspire the awe and wonder that the migratory monarch butterfly commands,” said Dr. Sean T. O’Brien, President and CEO of Nature Serve. “While efforts to protect this species are encouraging, much is still needed to ensure its long-term survival.”

What can be done to case the problem? A middle-of-the-road solution is gaining ground. Scientists recommend promoting the growth of native milkweed and nectar flowers. Monarch butterflies are a common backyard insect in America, so everyone can contribute their share.   —     4    . They can also plant flowers for monarchs. — Those flowers will provide nectar for monarchs when they bloom.

3 . The Maya loved cacao so much that they used the beans as currency. They also believed it is good for you — which many people still say today about cacao’s most famous byproduct, chocolate.     1    . While some have suggested that less than an ounce of dark chocolate might improve heart health, much of the research doesn’t involve eating actual chocolate but rather its components-flavanol, especially.

    2    . In a clinical trial of 21,000 adults, they found that the half of the group that took500mg of. cocoa flavanol supplements daily had a significantly lower risk of death from cardiovascular disease than those who had taken a placebo (安慰剂).

Flavanols may also boost insulin sensitivity, according to some studies, which might be helpful in reducing the risk of type 2 diabetes (糖尿病).     3    . Those at risk of diabetes might be wise to choose a cacao-inspired supplement instead of eating chocolate — and the sugar it contains. Other research suggests that the flavanols found in cacao (also present in fruits, vegetables, and tea) could slow cognitive decline during aging, or even boost brain performance by improving blood flow to the cerebral cortex.

What these findings mean for chocolate is limited, however. Participants would have had to eat multiple fat and sugar filled chocolate bars a day to source 500mg of flavanols.     4    . So understanding why certain types of chocolate are healthier than the rest is the focus of further research.

5 . A Victory for Women in Economics

Economic history has long been documented through a male perspective, putting emphasis on the contributions of men and their viewpoints. For proof, just look to the Nobel Memorial Prize in Economic Sciences.     1     The third, Harvard labor economist Claudia Goldin, won the prize in 2023, for her decades of work studying the gender pay gap.

    2     This narrow view might not appeal to everyone. Women in particular tend to be drawn to areas that have a direct impact on social challenges, such as health economics, development economics and education economics. But those fields don’t get as much attention and are sometimes not even recognized as economics at all.

Not only are women insufficiently represented as economists, economics as a field has historically ignored the role women play in the economy.     3     This resulted in economists failing to appreciate the unpaid labor that women provided in households and continuing to shape their analyses based on their traditional gender role beliefs.

Goldin has challenged the traditional male-centered world and turned the attention to women’s economic roles and challenges. Her Nobel recognition isn’t merely an honor for her individual achievements. It shows the world how inclusive, diverse and interconnected the field truly is.     4    

7 . The Psychology of Giving: Why do People Give to Charity?

Every day, leaders in the nonprofit sector invest valuable time, energy, and money into educating and spreading awareness of their mission in the hopes that this will increase support for their nonprofit. They assume that if only more people knew about a school’s budget cuts, for example, then they would surely donate! So, they bombard (连续轰炸) potential supporters with depressing statistics or complex arguments.     1    .

Why do people donate to charity? While it’s true that donors and volunteers are motivated to make the world a better place because it’s the right thing to do, that’s not the entire—or even the primary—reason for their generosity.     2    . In other words, we give because it feels good and that good feeling connects us to others in ways that we find satisfying. While that might sound selfish, all it really means is that people are wired to feel happy when they’re being kind.

    3    . Nobody wants to read yet another article about how the world is falling to pieces. Emphasize the good that’s being done at your organization so that your donors feel empowered, not depressed.

Since we give in part because it solidifies our connections to others, make sure that your communication with your donors is personal and specific (i.e. begin correspondence with “Dear Anna,” not “Dear Donor”). Prioritize community by finding ways to connect with your supporters on a personal level and give them the opportunity to interact with each other, whether it’s through a monthly video call or a donor appreciation night.     4    .

Remember that, at base, all philanthropic work is fundamentally a social act, so aim to make your donors feel like they’re a part of a broader community in which they are included, valued, and seen.

8 . A flexible patch could help people with voice disorders talk

The human voice, with its unique ability to attract audiences, express love and sometimes annoy neighbors, is a delibate thing. Doppler’s vocal cords can easily get damaged by stress, infections, or overuse.     1    . According to a 2005 study, 30% of the population will experience a voice disorder at some point in their life.

Researchers from the University of California, Los Angeles, have developed a soft patch that attaches to the neck, detecting muscle movements and translating them into clear speech using machine-learning algorithms. Even though the device is still in the early stages, it could be a significant improvement over existing communication aids for those who have lost their voice.     2     More complex aids such as electrolarynxes, external devices held against the throat, or surgical options, can be invasive or require special training to use. This patch would theoretically be able to clean all the obstacles.

The patch works based on the magneto-elastic (磁弹性的) effect When magnetic nanoparticles are mixed into flexible materials like elastic or silicone, stretching the material can change its magnetic properties. Every time the material changes shape, the particles either rotate or move against each other, altering the material’s magnetic strength. The patch, with its copper coil border that creates a stable magnetic field, can precisely track these changes.

    3     In a trial with eight participants, the researchers captured the signals as the subjects spoke and mouthed five different sentences (including: “Hope your experiments are going well!”, “Merry Christmas!” and “I love you!”). They then trained a machine-learning model to recognize the distinct patterns of the electrical signals associated with each sentence. This algorithm was then able to predict which of the five sentences the participants spoke — whether aloud or in silence — with more than 90% accuracy.

The patch is also designed to be user-friendly. It stays on even when the skin is sweaty and can be worn for 40 minutes without getting too warm.

However, there is more work to be done. For now the device can only recognize five pre-trained phrases.     4     To make it practical at scale, the researchers will need to collect a lot more data.

9 . Nature’s Gigantic Snow Plough

On January 10, 1962, an enormous piece of glacier broke away and collapsed down the side of a mountain in Peru. A mere seven minutes later, when cascading ice finally came to a stop ten miles down the mountain, it had taken the lives of 4,000 people. This disaster is one of the most “destructive” examples of a very common event: an avalanche (雪崩) of snow or ice. Because it is extremely cold at very high altitudes, snow rarely melts.     1     Glaciers are eventually created when the weight of the snow is so great that the lower layers are pressed into solid ice.     2     As snow accumulates on a steep slope, it reaches a critical point at which the slightest vibration will send it sliding into the valley below.

Even an avalanche of light power can be dangerous, but the Peruvian disaster was particularly terrible because it was caused by a heavy layer of ice.     3     As it crashed down the steep mountainside like a gigantic snow plough, it swept up trees, boulders and tons of topsoil, and completely crushed and destroyed the six villages that lay in its path.

At present there is no way to predict or avoid such enormous avalanches, but luckily, they are very rare.     4     In the future, perhaps dangerous masses of snow and ice can be found and removed before they take human lives?

10 . Health in space

Astronaut Frank Rubiales has returned to Earth after 371 days in space.     1       Unlucky for him, but very lucky for scientists who want to see what effects spending an extended time in space has on the human body.

Being in space can affect physical wellbeing.     2     Astronauts are recommended 150 minutes of exercise per day to counteract this. Also, space traveller’s eyes can be affected by the way that fluids act in zero-gravity. Outside the protection of the Earth’s atmosphere, astronauts are exposed to much higher levels and different forms of solar radiation. This can potentially cause long-term health problems, such as cancer.

It’s not just physical health that is affected by being in space. Our mental health can be damaged if we don’t get enough sleep. On earth, our bodies respond through circadian rhythms (昼夜节奏) to the Sun rising and setting to help us sleep, but astronauts on board the International Space Station see 16 sunsets and sunrises every day. This means that avoiding sleep deprivation is a challenge. Isolation, and spending all your time with a small group of people can also affect mental health. Along with isolation, is the pressure that comes from being constantly monitored by experts back on Earth. With possible future missions to Mars predicted to last three years, tensions within the crew could become heightened.     3    

Developing new techniques and technology to support astronauts’ health will enable more ambitious future missions.     4     The Canadian Space Agency is using its expertise to improve health care for people living in remote regions. The technology that supports robots used in space is now being used in surgery in normal hospitals, while pressure suits are being used to treat post-pregnancy complications.
