Fire has always been a part of California's natural history. But several centuries of human settlement have created new conditions that promote its spread.Studies have shown human ignition is to blame for 84% of all wildfires in the United States,and 97% of all those that threaten homes.

Human-caused fires always seemed more extreme, says Stijn Hantson,a fire ecologist at the University of California,Irvine,who led the new research. But measurements of how fast they spread and their impacts on ecosystems (生态系统) in California had not been explored, he notes.

To examine those differences, Hantson and his colleagues analyzed satellite data for 214 wildfires in California between 2012 and 2018.Human-caused fires typically spread about 1.83 kilometers per day, more than twice as fast as lightning-ignited burns,the team reports.The faster spreading fires also burned more violently and killed "double or triple" the trees as lightning-caused ones.

However, there is no fundamental difference in the chemistry of a human-caused blaze. "A fire is a fire" Hantson says. "It's the surrounding things that matter." Causes of fires ranging from improperly thrown cigarettes to sparking (冒火花) power lines could ignite a blaze on any given day, he says, while lightning strikes and dry thunderstorms only happen seasonally.

The researchers tracked meteorological data and found that human-caused fires were more likely to start on days with extreme weather conditions,and were more associated with drier,less-forested landscapes. This adds to scientists' understanding of how humans are extending the fire season, says Nathan Mietkiewicz, an ecologist with the National Ecological Observation Network.

The robot is soft and covered in fur. It contains small airbags internally that inflate(膨胀)in response to hand movement. Participants in the study who wore the robot while subjected to a medium heat stimulation, experienced less pain in the test than those who did not wear the robot. The test proved that the pain and anxiety being felt could be reduced sharply bylessening the experience of pain through using the robot.

The research team checked the effectiveness of the wearable robot while being handled by participants under certain conditions, based on the clenching of the hand. The team placed painful heat stimulation on the other arm that was not holding the robot. They then measured cortisol levels from the participants' saliva samples, suggesting levels of stress hormones. The pain felt by the patients was given specific ratings and was also recorded using an assessment scale. The people in the study were given a survey test to assess their fear of injections before and after the experiment with the wearable robot was completed.

The study proved that holding the robot can case the experience of patients who were receiving injections. The research team hopes to use this study to advance the robot for use during painful situations, such as getting medical shots or similar conditions.

Yollando is also known as Yanming, the Chinese name he was given by his teacher at the Shaolin Temple, where the "Shaolin kung fu" was born, and which today is like a magnet (磁铁) for fans from all over the world.

At the time, Yollando was a student at the Felix Houphouet-Boigny University in Abidjan. Motivated by his passion for Chinese culture, he signed up at the Confucius Institute to study Chinese. In late 2016, he had the opportunity to visit the temple in Henan Province on a three-month exchange. This experience defined his close relationship with traditional Chinese culture.

After returning to Cote d'Ivoire, Yollando continued to practice Chinese and study traditional Chinese culture. In July 2017, he returned to the Shaolin Temple again and remained there for six years. His years at the temple reading, exercising, practicing kung fu and meditation (冥想) greatly changed him, and allowed him to better understand and appreciate traditional Chinese culture.

He says the most impressive things he noticed that rooted in Chinese culture are the love of work, respect and recognition. At the end of 2022, when he completed his studies at the temple, he began working at a Shaolin cultural center in Zambia. The first of its kind in Africa, the center is home to 30 orphans (孤儿), who are taught Chinese language and traditional Chinese culture, including kung fu, as part of the course.

For Yollando, the purpose of studying Chinese culture was to be able to return to Africa to introduce Chinese values to his compatriots (同胞). "The culture fascinated me because in China, people make an effort to work better, and they are very respectful and grateful to their family and country," he says.
