1 . In 1959, Handler changed how toy dolls were made when she introduced “Barbie” to the world. With her mature figure, Barbie was one of the first “grown-up” dolls to hit the retail market.
Handler wanted to create a toy that was different from the baby dolls that dominated little girls’ toy boxes. She wanted a doll that girls could project their future dreams upon and allowed for limitless clothing and career choices. Inspired by paper dolls of the time, Handler, to much disagreement, made sure Barbie had the body of a grown woman.
“My own philosophy of Barbie,” Handler wrote in her autobiography, “was that through the doll, the little girl could be anything she wanted to be. Barbie always represented the fact that a woman had choices.”
There’s even a Barbie for cancer patients — Brave Barbie — a partnership between Mattel and CureSearch that sends a bald (光头的) Barbie to families affected by cancer. “Gifting my daughter a Barbie who suffered from cancer was tremendous,” Michelle, a cancer survivor said, “We would play with that Barbie together and I’d heartbreakingly watch her pretend to take the doll to the hospital for chemo (化疗), or place its long wig on top of its head and tell the doll ‘It’s time to be beautiful again.’”
Bald Barbie was super brave and went on awesome adventures after chemo. Sometimes she felt sick and needed to sleep, but would feel much better after a rest. Bald Barbie always beat the cancer and went on to live a long and happy life with her family. That Barbie became so much more than a plastic doll — she was a means of communication and a coping mechanism during an extremely distressing time for little families.

2 . People have come to understand the enormous impacts-beneficial as well as harmful- plastics have on human lives and the environment. As polymer (聚合物) scientists committed to inventing sustainable solutions for real-world problems, we set out to tackle the issue of plastic waste by rethinking the way polymers are designed so we could make plastics with recyclability built right in.
Everyday items including milk jug, grocery bags, and takeout containers are made from a class of polymers called polyolefins. These plastics are really durable (耐用的) because the chemical bonds in those polymers are extremely stable. In a world set up for disposable (一次性的) items, durability is no longer a design feature but rather a design drawback. Imagine if half the plastics used today were recyclable through twice as many processes as they are now. Also conventional recycling requires careful sorting of all the collected materials, which can be challenging with so many different plastics. For example, separating paper from metal doesn’t require complex technology, but sorting a container from a milk jug of a different polyolefin is difficult to do without the occasional mistake.
In a study published in Science in October 2023, we described a series of polymers with only two building blocks-one soft polymer and one hard polymer-that behave like polyolefins but could be chemically recycled. Connecting two different polymers multiple times until they form a single, long molecule (分子) creates what’s called a multiblock polymer. By changing how much of each polymer type goes into the multiblock polymer, our team produced a wide range of materials with properties that covered all polyolefin types.
Using the same strategy but by adding hydrogen, we could disconnect the polymers back into their building blocks and easily separate them to use again. When we made new polymers out of these recycled plastics, they performed just as well as the original materials even after several rounds of chemical recycling. So we were able to create materials with similar properties of the plastics the world relies on. We believe this work is a step toward more sustainable plastics.

3 . Hiring processes can be thought of as a battle between integrity and dishonesty. You might imagine this is a simple fight between truth-seeking firms and self-promoting candidates, and to a certain extent it is. But companies themselves are prone (有倾向的) to bend reality out of shape in ways that are self-defeating.
Start with the obvious wrongdoers: job applicants. When it comes to writing the resume (简历), they tend to massage (美化) reality into the most appealing shape possible. Everyone beyond a certain level of experience is a transformational leader personally responsible for generating millions income; the world economy would be about 15 times bigger than it actually is if all such claims were true. The average British spends four and a half hours a day watching TV and online videos. But each average job candidate is an enthusiast for public welfare, using their spare time only for worthy purposes, like volunteering in soup kitchens.
But the tendency to stretch the truth infects companies as well as applicants. The typical firm will write a job description that invariably describes the work environment as fast-paced and innovative, and then lays out a set of improbable requirements for the “ideal candidate”, someone who almost by definition does not exist. Sometimes, the requirements include an ability to go back and change the course of history.
Too few firms offer an accurate account of what a position actually involves in their job previews, which are supposed to give prospective employees a genuine sense of the negatives and positives of the job, as well as a clear idea of the company’s corporate culture. One effective strategy is to lay out in text or video, what a typical day in the role would look like.
Such honesty can be its own reward. Research has long suggested that realistic job previews lead to lower turnover and higher employee satisfaction. A paper in 2011 by David Eamest of Towson University and his co-authors concluded that favourable perceptions of the organisation’s honesty are the best explanation for why. So a process designed to uncover the truth about job applicants would run a lot more smoothly if firms were also honest about themselves.

5 . “ Humans and machine algorithms (算法) have complementary (互补的) strengths and weaknesses. Each uses different sources of information and strategies to make predictions and decisions, ” said Mark Steyvers, UCI professor of cognitive sciences. “ We show through experiments that humans can improve the predictions of AI even when human accuracy is below that of the AI, and vice versa (反之亦然). This accuracy is higher than combining predictions from two individuals or two AI algorithms. ”
To test the framework, researchers conducted an image classification experiment where human participants and computer algorithms worked separately to correctly identify disorderly pictures of animals and everyday items including chairs, bottles, bicycles and trucks. The human participants ranked their confidence in the accuracy of each image identification as low, medium or high, while the machine classifier generated a continuous score. The results showed large differences in confidence between humans and AI algorithms across images.
“ Human participants were confident that a particular picture contained a chair, for example, while the AI algorithm was confused about the image, ” said Padhraic Smyth, UCI Chancellor’s Professor of computer science. “ Similarly, the AI algorithm was able to confidently provide a label for the object shown, while human participants were unsure if the disorderly picture contained any recognizable object. ”
When predictions and confidence scores from both were combined using the researchers’ new Bayesian framework, the mixed model led to better performance than either human or machine predictions achieved alone.
“ While the past research has demonstrated the benefits of combining machine predictions or combining human predictions, this work shows a new direction in demonstrating the potential of combining human and machine predictions, pointing to new and improved approaches to human-AI cooperation, ” Smyth said.
“ The blend of cognitive science focusing on understanding how humans think and behave and computer science in which technologies are produced will provide further insight into how humans and machines can cooperate to build more accurate artificially intelligent systems, ” the researchers said.

6 . Until recently, gravitational waves could have been the stuff of Einstein’s imagination. Before they were detected, these waves in space time existed only in the physicist’s general theory of relativity, as far as scientists knew. Now, researchers are on the hunt for more ways to detect the waves. “The study of gravitational waves is booming,” says astrophysicist Karan Jani of Vanderbilt University in Nashville. “This is just remarkable. No field I can think of in fundamental physics has seen progress this fast.”
Just as light comes in a variety of wavelengths, so do gravitational waves. Different wave lengths point to different types of origins of the universe and require different kinds of detectors. Gravitational waves with wavelengths of a few thousand kilometers—like those detected by the United States, Italy and Japan—come mostly from pairs of black holes 10 or so times the mass of the sun, or from collisions of dense cosmic blocks called neutron stars (中子星). These detectors could also spot waves from certain types of exploding stars and rapidly moving neutron stars.
In contrast, huge waves that span light-years are thought to be created by orbiting pairs of bigger black holes with masses billions of times that of the sun. In June, scientists reported the first strong evidence of these types of waves by turning the entire galaxy (星系) into a detector, watching how the waves make slight changes to the timing of regular blinks from neutron stars throughout the Milky Way.
Physicists now hope to dive into a vast, cosmic ocean of gravitational waves of all sorts of sizes. These waves could reveal new details about the secret lives of exotic objects such as black holes and unknown parts of the universe.
Physicist Jason Hogan of Stanford University thinks there are still a lot of gaps in the coverage of wavelengths. “But it makes sense to cover all the bases. Who knows what else we may find?” he says. The search for capturing the full complement of the universe’s gravitational waves exactly could take observatories out into the moon, to the atomic area and elsewhere.

7 . More than 80 percent of global heat is absorbed by the ocean, which has a massive capacity to store and give off heat. High sea-surface temperatures are causing long-term damage to coral reefs (珊瑚礁). Corals are dying. The IPCC (政府间气候变化专门委员会) projects that up to 90 percent of coral reefs could disappear if global warming reaches 1.5℃. Another reason corals are in trouble is because of ocean acidification. Higher carbon dioxide levels have shift ed the chemistry of the ocean, making it more acidic, and corals and sea creatures have trouble growing in acidic conditions.
When ocean water warms, it expands in volume. This is a major cause of the rise in sea levels, along with the water added to the ocean by the melting of land-based glaciers (冰川). The sea level has risen by an average of 20 centimeters since the late 19th century, and the research by scientists studying the last 25 years of satellite data found that the ocean water is rising faster and faster. If it continues at its current rate, the rise in sea level by 2100 will be more than double the current estimates. Sea level rise leads to the destruction of coastal wetlands, flooding and damage to water ecosystems.
Temperature and precipitation (沉淀) are key elements of climate. A warmer climate means that more water rises from both the land and ocean, and a warmer atmosphere holds more of that water. Scientists have noticed that there are more heavy rainfall events. Additionally, higher water temperature in streams, lakes, and rivers lead to lower levels of dissolved oxygen in the water, which impacts the survival and populations of fish and other sea life.
Especially troubling are the extreme weather events that are happening more often around the world. Hurricanes are ramping up in intensity, particularly in North Atlantic. The year 2017 was a busy one for Atlantic hurricanes. Meanwhile, in the western United States, the state of California has had record-setting drought conditions, which began in 2012.

8 . Some libraries use unique architecture to encourage visitors to explore the bookshelves and settle down with a new book, or use roving libraries to bring books to hard-to-reach populations. No matter how they achieve it, these novel libraries are keeping the magic of reading alive.
Bishan Library (Singapore)
Built in 2006, this library with skylights and trellises, is meant to invoke a modern glass treehouse. Glass pods of varying colors stick out of the building randomly to create cozy yet airy corners for reading throughout the building. At the same time, a more open-plan children’s room on the basement level invites interaction while preventing noise from filtering upward and disturbing those concentrating in the lofty perches above.
Stuttgart City Library (Stuttgart, Germany)
Opened in 2011, this nine-story public library is characterized by its attractive white color scheme (lit by blue light at night), its bold cubic shape. This cultural center for the city, designed to feel open and full of light, can be entered from any of its four sides, and people can borrow artwork as well as books.
The Camel Library Service (North Eastern Province, Kenya)
To combat low literacy rates in the desert of Kenya, the government created a roaming library composed of nine camels bringing books to villages. The library travels four days a week serving the region’s nomadic people. With more funding, they plan to increase their reach both in distance and the books they carry.
Macquarie University Library (Sydney, Australia)
A wonderful combination of cutting-edge and sustainable ideas, this building was made from recycled materials, features a green roof, and was designed to look like the shape of a eucalyptus tree. It is also state of the art, using robot cranes to bring requested books to the front desk.

9 . Whenever you pick up an apple and prepare to eat it, you may notice a small sticker attached to the fruit with a row of four or five numbers on it.That string of numbers is something called a Price Look-Up (PLU) code.
From the code, you can also know what specific variety of a particular fruit or vegetable you’re going to enjoy — whether it’s a Honeycrisp apple or a Shamouti orange. And it may tell you the size of the fruit or vegetable.
A volunteer committee developed PLUs in 1988. One important reason why PLUs were invented was to enable supermarkets to tell the difference between conventionally grown fruits and vegetables and higher-priced organic food. As organic produce was being introduced then, cashiers often wrongly sold it at the conventional price.
| A．The function is fairly simple. |
| B．PLU codes have a long history. |
| C．You probably think organic food is healthier. |
| D．The appearance of PLUs helped solve this problem. |
| E．Besides, it shows where the fruit or vegetable comes from. |
| F．The future of fruit and vegetable stickers is still uncertain. |
| G．You can use the PLU search app to know what a particular one means. |
10 . A walk around the workplace is also a trip back in time. The office is where colleagues meet, work and bond. But it is also a time capsule, a place where the traces of historic patterns of working are visible everywhere. The pandemic has heightened this sense of office as a dig site for corporate archaeologists.
The most obvious object is the landline phone(固定电话), a reminder of the days when mobility meant being able to stand up and keep talking. Long after people have junked them in their personal lives - less than 15% of Americans aged between 25 and 34 had one at home in the second half of 2021- landline phones survive in offices.
There might be good reasons for its persistence: they offer a more secure and stable connection than mobile phones, and no one worries that they are about to run out of battery. In practice, the habit of using them was definitely lost during the pandemic. Now they sit on desk after desk, rows of buttons unpressed, ring tones unheard.
Landline phones were already well on their way out before covid-19 struck. Whiteboard charts have suffered a swifter reverse. These objects signal a particular type of pain- people physically crowded together into a room while a manager sketches a graph with a marker pen and points meaningfully to the top-right-hand corner, giving requirements never to be satisfied. This manager is still making graphs but is now much more likely to use a PowerPoint. The crowd is still being tortured but is now much more likely to be watching on the screen. The office still has whiteboards, but they are left in corners and the charts on them are slowly yellowing.
Real archaeologists need tools and time to do their painstaking work: brushes, shovels and picks. Corporate archaeology is easier: you just need eyes and a memory of how things used to be. But you also need to be quick as more and more work places are revamped for the post-pandemic era. Now its time to take a careful look around the office: you may see something that will soon seem outdated.
