1 . When we’re on the treadmill (跑步机), we’re more likely to bethinking about whether we’re going to make it another mile than’what’s in our workout clothing. But our favorite sports ch ab are likely to be made from synthetic (合成的) fabrics, all of which are essentially plastic often created with harmful chemical additives. Now, a study conducted by the University of Birmingham shows the chemical additives from our workout clothing are available to be absorbed through our skin.
Previously, researchers have tended to focus on our exposure to plastic through diet,but the new study raises awareness that humans can be expesed to plastic chemicals through our skin, too. And because harmful chemicals accumulate lowly and stick around in our bodies, repeared and multi-source exposure can result in having high concentrations of chemicals inside us, potentially contributing to health effects.
The Birmingham study focused on a class of compounds(化合物)called brominated flame retardants(BFRs), which are used to prevent burning in a wide range of consumer products including fabries, and are linked to adverse health effects such as hormonal disorders and mental problems.
It’s known that sweat contains oil. Researchers found the oil has a chemical nature that encourages the chemicals in plastic to dissolve and spread.“In short, oil substances in our sweat help the bad chemicals to come out of the microplastic fibers and become available for human absorption,”says Dr. Abdallah of the Urnversity of Birmingham. An easy way to avoid exposure to these chemicals is to wear clothing made of sustainably produced textiles, which dont contain the bad chemicals associated with plastic materials. Check fabric labels for items that are mostly organic cotton, he mp or merino wool. Visit brand websites to see if they make an effort to list their suppliers, and where their products come from, including their dye houses and mills. Abdallah says he minimizes synthetic fabrics in his home, meanwhile wearing natural fibers like cotton. “Why be exposed to these chemicals even at low levels?”he says.“Why not avoid the risks?”

3 . Baidu, a Chinese search engine and artificial intelligence firm, announced its latest electric autonomous driving vehicle, Apollo RT6, on Thursday. The new vehicle is a fully electric vehicle with a steering wheel (方向盘) that can be removed when not required. It will cost ¥250,000 per unit.
“The steering-wheel-free design allows more space for extra seating or other additions and the massive cost reduction will enable us to put tens of thousands of autonomous vehicles into operation across China,” Robin Li, co-founder and CEO of Baidu, said at the firm's Baidu World Conference Thursday. “We are moving towards a future where taking a robotaxi will be half the cost of taking a taxi today.”
Baidu already runs Apollo Go and Apollo Moon, taxi services using self-driving robotaxis with safety staff seated in the driver or passenger seat. They have been in operation in big cities like Beijing, Shanghai, Shenzhen and Guangzhou, although the service is limited to specific areas. The new vehicle will soon join those robotaxis.
The RT6 has reached the industry's Level 4 out of five possible levels of technology. That means its systems can operate without a driver but must be pre-loaded with a detailed map, thus limiting the areas where the vehicles can operate. Lower levels of self-driving technology have been available for decades. For example, many Level-3 vehicles allow hands-free highway driving. Other kinds of self-driving robot vehicles are already widely used in factories warehouses and other tightly controlled settings.
Compared to previous generations where the technology was mainly used on conventional vehicles, the Apollo RT6 was designed specifically with fully autonomous driving in mind.
Baidu is best known for its search engine and online advertising services, but in recent years it has invested heavily in autonomous driving and artificial intelligence technology, including automated personal assistants and AI chips.

4 . Sara Dykman is on a 10, 000-mile bike trip, following the monarch butterfly from Mexico through the UnitedStates and Canada and back again. The purpose of her journey is not just to mark the butterfly’s migrating (迁徙) road, but to warn about the threat it faces — and what we can do to help it.
When I reached Dykman by phone, she was biking through Iowa cornfields. She said she feels more upset than usual, because of what she is seeing — or not seeing — on her travels: Fewer butterflies and milkweed. “In the last two decades, the butterfly population has declined by about 90 percent as a result of the loss of milkweed, a native plant that the butterflies need as part of their life cycle,” she said.
Butterflies go through a four-stage life cycle. In February and March, the adult monarch butterflies come out of winter sleep to look for a mate. Then they migrate north and east to lay their eggs on milkweed plants. It takes about four days for the eggs to hatch. Then the baby caterpillars (毛毛虫) spend much of their time eating milkweed in order to grow. About two weeks later, the fully grown caterpillars will attach themselves to plant branches or leaves to change into butterflies.
But Dykman is not in total despair. A solution, she says, exists within the reach of everyone who owns a home; simply planting some milkweed in the yards to help the butterflies on their journey.
Dykman lives a life as simple and rootless as the butterflies she loves. She doesn’t own a house or car or eat out at restaurants. She carries only what she needs; a sleeping bag and clothing. People help along the way by providing a place to stay and a meal.
“I have failed at everything normal, but I’m pretty good at doing the less normal things,” she admits in her new book Cycling With Butterflies.
“But this trip is about solutions, and it’s about helping people see the consequences of their actions,” she said on the phone.

5 . As the movie Nomadland revealed to the world, ever since the 2008 financial collapse, people have mowed into vehicles as a way of surviving the high cost of living. The pandemic also fuelled an increase in the nomadic (流浪的) lifestyle.
In 2020, my co-researcher Scott Rankin and I looked at how people who live in vehicles balance work and life. This year, I continued my research to better understand why people live this way.
People of all ages and genders take part in van (面包车) living. The average age of van dwellers (居住者) was 42. After asking respondents to rank the reasons why they chose to live in a vehicle, ranked from top to bottom are: 1) freedom, 2) low cost of living, 3) adventure, 4)connection to nature,5)minimalism,6)avoiding undesirable weather,7)starting a new life, 8)pursuing work in different places, 9)working remotely, 10)to be on their own, 11)to join a partner, 12)to leave a partner.
Above all else, vehicle dwellers sought to be free. Whether they were a re tire n in a $100,000 Mercedes van, or young Canadians working from a $5 ,000 van, respondents wanted to be able to move their home to any place that was best for them. For others, living in a vehicle minimized their costs, allowing them to work less or make the most of their income without paying rent.
As it turns out, van living is not a fad. While many respondents were new to van living, on average, respondents indicated they had been living in a vehicle for an average of 2.5 years. Seventy-eight per cent of respondents permanently lived in a vehicle.
As the housing crisis deepens, we may see more people consider van living as a means of surviving the high cost of living. It will be up to the government to accept this alternative living arrangement, and consider having parking and facilities to support those who choose to live this way.

6 . We sometimes think that everything was much better and easier in the past. It’s one of the tricks our minds play on us, especially when we are in low spirits.
Actually, it’s unlikely that things were objectively better in the past. This form of thinking is called rosy retrospection, which is a well-studied cognitive bias. It happens because when we think about the past, we are more likely to focus on positive generalities than annoying details.
If you think back to a holiday with your family five years ago, you’re likely to recall the beautiful views rather than the uncomfortable bed. In other words, the negative details disappear from our memory over time while the positive ones remain.
Rosy retrospection can influence how we make decisions, and it’s one of the reasons why we easily return into problematic relationships. The longer it is since we experienced the negative influence of a relationship, the more likely we are to let the good memories outweigh the bad memories and to perhaps forgive unforgivable behavior. It’s always a good idea to review our nostalgic (怀旧的) feelings with a healthy degree of doubt.
But rosy retrospection does serve an important purpose. It keeps us in a positive state of mind in the present and is important to our psychological wellbeing. In fact, people who tend to remember negative experiences more than positive ones are likely to exhibit psychological disorders. Research generally suggests that our happiest days are still to come. And even if they’re not, it’s still important to believe that they are. Don’t shy away from looking upon the past with a certain degree of nostalgia. But, for the same reason, don’t use the past as an excuse to be unhappy in the present.

9 . “The era of global warming has ended and the era of global boiling has arrived,” the UN secretary general, Antonio Guterres, said after scientists confirmed July 2023 was the world’s hottest month on record.
“Humanity is in the hot seat,” Guterres told a press conference on Thursday. “For vast parts of North America, Asia, Africa and Europe, it is a cruel summer. For the entire planet, it is a disaster. And for scientists, it is clear that humans are to blame. Climate change is here, it is terrifying, and it is just the beginning. The era of global warming has ended; the era of global boiling has arrived.”
Guterres urged politicians to take swift action. “The air is unbreathable, the heat is unbearable, and the level of fossil fuel profits and climate inaction is unacceptable. Leaders must lead. No more hesitancy, no more excuses, and no more waiting for others to move first. There is simply no more time for that.”
“It is still possible to limit global temperature rise to 1.5℃and avoid the very worst of climate change but only with dramatic, immediate climate action. We have seen some progress, but none of this is going far enough or fast enough. Accelerating temperatures demand accelerated action.”
The WMO secretary general, Petteri Taalas, said, “The need to reduce greenhouse gas emissions is more urgent than ever before. Climate action is not a luxury but a must.”
Other climate scientists confirmed the findings. Karsten Haustein at Leipzig University found the world was 1.5℃ hotter in July 2023 than in the average July before industrialisation.
Marina Romanello, a climate and health researcher at University College London, said, “We have data showing how the very foundations of health are being undermined by climate change. But we still have time today to turn the tide and to ensure a liveable future for us and our children.”
