2 . Scientists have already applied robots like Roomba to work in the agriculture (农业). A Roomba works because it has wheels that function well on flat ground. However, fields are full of rough and rocky environments, which means it is difficult for robots to work in the fields. Luckily, scientists thought of centipedes (蜈蚣). With tens to hundreds of legs, they can move on any places without stopping. If they stop moving their body parts and feet, they basically stop moving instantly.
A team led by Chong developed a theory that proposes that adding leg pairs to the robot increases its ability to move firmly over challenging environments.
To test this, Juntao conducted a series of experiments where he and Daniel Soto built models to simulate (模拟) different natural environments. He then tested the robot by increasing its number of legs by two each time, starting with six and finally increasing to 16. As the leg count increased, the robot could more easily move across the surfaces, even without sensors. Finally, they tested the robot outdoors on real environments, where it was able to move in a variety of environments.
The researchers are applying their discoveries to farming. Goldman has co-founded a company that wants to use these robots to weed (除草) farmland where weedkillers are ineffective. “It’s truly impressive to see the multilegged robot easily moves on both lab-based and outdoor environments,” Juntao said. “Now we are deciding the most suitable number of legs to achieve motion. In the future, we hope to apply them for space exploration, and even search and rescue.”

3 . Taking good care of your teeth may be linked to better brain health, according to a study published in the July 5, 2023, online issue of Neurology. “Our study found that gum (牙龈) disease and tooth loss were linked to brain shrinkage (萎缩) in the hippocampus (海马体) , which plays a role in memory and Alzheimer’s disease,” said study author Satoshi Yamaguchi, Ph. D. of Tohoku University in Sendai, Japan.
The study involved 172 people without memory problems. Their average age was 67. Participants had dental exams and took memory tests at the beginning of the study. They also had brain scans to measure the volume of their hippocampus at the beginning of the study. This was measured again four years later. For each participant, researchers counted the number of teeth and checked for the amount of gum disease.
Researchers found that the number of teeth and amount of gum disease was linked to changes in the left hippocampus of the brain. For people with mild gum disease, having fewer teeth was associated with a faster rate of brain shrinkage, which is the same for people with severe gum disease having more teeth. After adjusting for age, researchers found that for people with mild gum disease, the increase in the rate of brain shrinkage due to one less tooth was equal to nearly one year of brain aging. By contrast, for people with severe gum disease the increase in brain shrinkage due to one more tooth was equal to 1. 3 years of brain aging.
“These results highlight the importance of preserving the health of the teeth and not just maintaining the teeth,” Yamaguchi said. “The findings suggest that controlling the progression of gum disease through regular dental visits is important, and that teeth with severe gum disease may need to be removed and replaced with appropnate false ones.”
Yamaguchi said future studies are needed with larger groups of people. The limitation of the study is that it was conducted in one region of Japan, so the results may not be applied to other locations.

7 . Martin Kocher, an international business student at the University of Wisconsin-Eau Claire, has always been interested in exploring different cultures and traditions in preparation for a global career. Focusing on global management, he was super motivated (激励) to develop his career about sustainable development.
Kocher is set to graduate in May with a major in international business, expressing his gratitude to the university for training his international ambitions. After he completed the internship (实习) in Australia, he traveled to a small island of Lombok near Bali, Indonesia. A teacher at the local school told Kocher that the English language can empower students and allow them to bridge the cultural gap with people in other parts of the world, but the school lacked the resources.
As a result. when Kocher returned to U’W-Eau Claire, he founded Language 4 Lombok to connect English language resources from Chippewa Valley residents with the Indonesian island. Books from community book drives are shipped abroad to help children learn English.
His non-profit work is not his whole life. He is also a competitive diver, part-time real estate agent, enthusiastic photographer and writer. Dr. Kaishan Kong, a professor of Kocher said he is a real jack of all trades, and was impressed with his ability to connect different languages while maintaining an incredible enthusiasm for learning them.
Having benefited a lot from his own experiences, Kocher encourages others to travel and venture internationally, calling it “one of the best investments you can make in yourself.”

9 . Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website Book Crossing.com turns the page on the traditional idea of a book group.
Members go on the site and register (登记) the books they own and would like to share. Book Crossing provides an identification number (识别码) to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.
Bruce Pederson, the managing director of Book Crossing, says, “The two things that change your life are the people you meet and books you read. Book Crossing combines both.”
Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.
People who find a book can also leave a journal entry describing what they thought of it. E— mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.
Book Crossing is part of a trend (趋势) among people who want to get back to the “real” and not the virtual (虚拟).The site now has more than one million members in more than one hundred thirty—five countries.
