2 . 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 . Which is more important for parents, making more money to give the kids a better life or spending more time with them? It is a problem for parents and it is not easy to decide. A new study shows that today’s parents are spending more time with their children than parents in the past. According to the study, today’s college-educated mothers spend about 21.2 hours a week taking care of their children. But women with less education spend about 15.9 hours. Before 1995, it was only 12 hours.

Dads are spending more time on ball games. Before 1995, fathers with college educations only spent about 4.5 hours a week playing with their children. Today, it increases to 9.6 hours a week. For fathers with high school education, the time goes up from 3.7 hours to 6.8.

These days, parents don’t care more about the cleaning or the cooking. They are trying their best to spend time with their families. As for the kids, they don’t mind how much time their parents spend with them. They just want to enjoy the time their parents do be with them.

So, take part in the kids’ activities when you are with them, such as helping with homework or playing soccer with them.

6 . Thanksgiving isn’t just a holiday in the US. Some other countries have their own versions of Thanksgiving.

Brazil

Legend has it that Joaquim Nabuco, Brazil’s first ambassador (大使) to the US, enjoyed the American holiday so much that he persuaded his government to set up a similar day of thanks. Dia de Acao de Gracas is also celebrated every year on the fourth Thursday of November to give thanks for the fall harvest. The Brazilian holiday ends with a colorful and noisy carnival(狂欢节) and parade.

Japan

Japan’s version of the holiday, called “Kinro Kansha no Hi” or Labor Thanksgiving Day, is observed on November 23. It originated from an ancient rice harvest festival called Niiname-sai. Later, the holiday’s purpose was to celebrate the rights of workers. Today, Labor Thanksgiving Day is mainly observed with small acts of community service. Children often mark the occasion by handing out thank-you notes to firefighters, police officers, and other frontline workers.

Canada

Thanksgiving in Canada is a low-key affair with no big parades or retail sales. The holiday mainly focuses on families and friends getting together for a meal. While many parts of the country get the day off, it is an optional (可选择的) holiday in Prince Edward Island, New Brunswick, Nova Scotia, Newfoundland and Labrador. As a result, the celebrations often take place the weekend before the holiday.

Ghana

Ghana celebrates its version of Thanksgiving in August or September. As the story goes, the Ga settlers arrived in Ghana in the 16th century after facing lots of hardships during their travels across Africa. They celebrated their first harvest in Ghana with a feast, and a tradition was born. Before the festival, there is a month-long ban on noise, especially drumming. Similar to Thanksgiving, Homowo is a festival of food.

However, McCutchen isn't ______ about this at all. In fact, she says she'll ______ help anyone who's keen to do so, even if it means that they beat her to it.

8 . Dorothea Dix was born in 1802 in Massachusetts. When she was 12 years old, she left her unhappy home to live with her grandmother in Boston. There Dorothea went to school and was so quick at her lessons that two years later she went back to Worcester, Massachusetts and taught in a school for little children. She was only fourteen and rather small for her age. Anyway, she proved herself a good teacher, and the children loved her and respected her. In 1821, she opened a school for girls in Boston.

Gradually, her health broke down, and she began to think that she could never work any more, but after a long rest in England, she came back to America and did something far greater than teaching. She went through the whole country where she first observed the inhumane treatment of the mentally ill. During Dorothea’s traveling for nearly two years throughout the state, and meeting similar conditions, she always spoke kindly to the ill-treated, but she spoke wrathfully to the men who ill-treated them. In January 1843, she submitted to the Massachusetts legislature (立法机关) a detailed report of her fully documented findings.

In the next 40 years Dorothea inspired legislators in 15 US states and in Canada to establish state hospitals for the mentally ill. Her continuous efforts directly affected the building of 32 institutions in the United States. When the Civil War broke out, she went straight to Washington and offered to nurse the soldiers without pay. She hired houses to keep supplies in and bought an ambulance. She gave her time, strength and money to her country.

Dorothea Dix has been called the most useful woman of America. She is an, American educator, social reformer and humanitarian whose devotion to the welfare of the mentally ill led to widespread reforms in the United States and abroad.

9 . Scientists are now digging into precisely why exercise holds so many benefits for our mental health and memory. The answer, studies say, lies in our brain chemistry.

Each time you work up a sweat, your body releases feel-good happy hormones (荷尔蒙), including endorphins, dopamine and endocannabinoids, the latter being responsible for the so-called runner’s high. Now researchers are also pointing to myokines (肌肉因子) as an important contributor to the mental health benefits of exercise. When our muscles contract, myokines are released into the bloodstream, helping your muscles and organs communicate. They think this communication increases resilience to stress, reduces symptoms of mental suffering and anxiety and has a direct effect on depression.

A 2021 scientific report published in Neuropharmacology showed evidence that myokines boost brain function, like improving memory and mood. “Myokines reduce systemic inflammation (炎症), which is especially beneficial for people with drug-resistant depression whose low mood is linked to high inflammation,” explains Dr Jennifer Heisz, an expert in brain health and associate professor in the department of kinesiology at McMaster University in Canada.

A recent study published in the British Journal of Sports Medicine showed that treatment for depression can be much more effective when physical activity is added to the usual care. Participants found benefits after 12 weeks of exercising for 30 to 60 minutes a day. “While exercise is not a replacement for professional mental health treatment, physical activity can complement and enhance the effects of the treatment,” says lead researcher Ben Singh, a research fellow at the University of South Australia.

“It is amazing to consider how moving our bodies can heal our minds,” says Heisz. Whether you’re cycling, walking around your neighbourhood or doing yoga, getting sweaty is good for your body and mind. To get the biggest overall health boost, the key is to zero in on sports and activities you enjoy, so you’ll keep going back to them.

10 . The maleo (塚雉), a bird with black feathers and a pink chest, is native to Indonesia’s Sulawesi island and a few neighboring ones. The International Union for Conservation of Nature (IUCN), which identifies wildlife across the world currently facing threats, estimates only 800 to 1,400 adult maleos remain in the wild. Experts do not know how many maleos still live across West Sulawesi island. They were only able to record the presence of nesting grounds in 23 villages based on reports from locals in the area. But of those, only 18 are considered active nesting areas.

Recently, the birds have been faced with new threats, which accelerate their decline. The Indonesian government plans to move the nation’s capital from Jakarta to a new city on Borneo island, which is just a six-hour boat trip apart from Sulawesi island. The island takes on the building of new roads and seaports to be used to transport materials to the new capital. Activities also include tree clearing, digging, and removing stones. The process already has changed the forest environment on West Sulawesi and is harming maleo nesting areas near the beach. These changes have made the trip for maleos to lay their eggs increasingly difficult.

Another problem has been poachers. The Associated Press reports that, regardless of official ban, they steal maleo eggs that the males’ parents have hidden in the sand, and sell the eggs for about $1 to people as food. The eggs are a traditional gift for many people in Mamuju and other parts of Sulawesi.

“As far as I know, maleo birds are in decline,” said Andi Aco Takdir, chief of the West Sulawesi Forestry Agency. He pointed to several reasons for the decline, including destruction of beach areas, and expanding human development activities. He added that government officials there are prepared to take steps to protect the maleos even with the new capital development. Andi said, “Nature conservation must be used as an achievement and must not be built leaving behind problems.”
