1 . A fully automated process, including a brand-new artificial intelligence(Al)tool, has successfully detected, identified(确认)and categorized its first supernova(超新星). Developed by an international organization led by Northwestern University, the new system automates the entire search for new supernovae across the night sky—effectively removing humans from the process. Not only does this rapidly speed up the process of analyzing and categorizing new supernova candidates(候选), but it also bypasses human errors.
The team reported to the astronomical community the launch and success of the new tool.called the Bright Transient Survey Bot(BTSbot), this week. In the past six years, humans have spent an estimated total of 2,200 hours checking and categorizing supernova candidates. With the new tool now officially online, researchers can redirect this precious time toward other responsibilities in order to speed up the discovery.
To detect and analyze supernovae, humans currently work hand in hand with robotic systems. First, robotic telescopes repeatedly image the same sections of the night sky, searching for new sources that were not present in previous images. Then, when these telescopes detect something new, humans take over. The researchers developed the BTSbot to cut out these human middlemen.
To test the BTSbot, the researchers looked to a newly discovered supernova candidate called SN2023tyk. The ZTF, a robotic observatory that images the night sky in a search for supernovae, first detected the source on Oct. 3. Examining ZTF’s data in real time, BTSbot found SN2023tyk on Oct.5. After determining that the candidate was a Type la supernova, the automated system publicly shared the discovery with the astronomical community on Oet.7.
In the first days of running BTSbot, Northwestern’s Nabeel Rehemtulla, who co-led the technology development, felt a mix of nervousness and excitement. “The beauty of it is that, once everything is turned on and working properly, we don’t actually do anything. We go to sleep at night, and, in the morning, we see that BTSbot and these other AIs firmly do their jobs,” he said.

2 . Paris mayor Anne Hidalgo has long worked to make her city less dependent on cars. She wanted to see more people using bicycles to get around. Over a number of years, the city government set limits on cars and increased the amount of bike paths from 200 kilometers to over 1,000 kilometers.
This year, Parisians are not complaining about too much automobile traffic. Instead, they say there are too many bikes. “Now, it’s really like a bike traffic jam(阻塞),” Thibault Quere, a spokesperson for France’s Federation of Bicycle Users, said. ”It’s kind of a good difficulty to have, especially when we think about what Paris used to be.”
Some famous roads along the River Seine are completely closed to cars. Now you see people riding bikes, running and walking with their families along the river. In another part of Paris, a bike path on Sebastopol Boulevard is one of the busiest in Europe, after opening in 2019. In one week in early September, it reached a record high of 124,000 riders.
The city will host the Summer Olympics in 2024 and plans to add more bike paths by then. Paris wants to reduce its pollution by half during the games, even as visitors from around the world will be in the city for the event. Organizers say all of the competition sites will be reachable by bike through a 60-kilometer network of bike paths.
The change to Paris, however, has not been easy. With more people using bikes, more people are making mistakes. Some of them are new to cycling and disobey traffic rules. But the environment may be improving. Cycling is good exercise and helps reduce pollution, which is still a problem for the large city. The French government blames atmospheric pollution for 48,000 early deaths in the country each year.
Hidalgo was re-elected in 2020 and plans to keep making what she calls a “Paris that breathes”. Her newest five-year bike plan includes over $250 million for more bike paths and bike parking. The new budget is an increase of over $100 million from her first five-year plan.

James Bradley had developed a strong passion for skiing. On a freezing cold Sunday in 2019, James, then a 16-year-old boy, headed to Aspen Mountain with his father to go skiing. They took a cable car to the top of the mountain and conquered the most challenging part of the long trail. Afterwards, they decided to follow different trails to go down the mountain respectively. That was when everything started to veer off course.
In the late afternoon, after finishing the final run through the side trial, his father arrived at the parking lot. Anxiously, he had waited here for his son for several hours. However, James never showed up.
It turned out that a fierce snowstorm had swept into the area as James was on his way down. Unable to see far and clearly, he turned off the path by accident and got lost. The dreadful snowstorm coupled with strong winds gained strength and enveloped everything, blocking his way back to the ski trails.
Before long, James slid down the mountain slope on his skis and stopped at the bottom of the mountain in the valley. Thanks to the thick snow, James didn’t get hurt and the winds weren’t as strong in the valley as they were up on the mountain. Looking around, he saw nothing but the branches of trees and the pure white snow. James had no idea where he was. Worse still, the sun began to sink and he was getting colder by the minute. Most worrisome of all was that he didn’t have any food or water with him, let alone his mobile phone or other supplies.
Standing alone in the wild and holding his large skis, cold and thirst, he couldn’t help thinking about the survival show Man vs. Wild that he used to watch. In the show, Bear Grylls was abandoned in a wild area like this and had to help himself out by using all sorts of survival skills. Yes! It was time to put the tips he had learned to use.
