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.

3 . The older you are, the less likely you are to swear (except in the car—studies say most people swear when driving). As we get older, swearing becomes part of the rich lexicon of language that we use to express ourselves, and while we might associate swear words with negative communication. Only eight percent of people actually swear to cause offence. “There are many other reasons that we swear, including positive uses like expressing excitement, emphasis.” says Dr Karyn Stapleton, a senior lecturer in Communication at Ulster University. “And there’s cathartic (宣泄的) swearing, which provides a means of releasing strong emotions, or feelings like anger, pain or frustration.”
Cathartic swearing fascinates scientists as it shows some really interesting facts about bad language. Studies at the UK’s Keele University revealed that when under stress, a person can think of considerably more swear words than someone asked to do the same task when relaxed, and it’s now suspected that rather than being controlled by the normal part of the brain that handles language (the left cortex), swear words are actually processed by the limbic (边缘的) system that normally controls emotional thoughts. Be warned though—the more you swear in general speech, the less effective the cathartic effects of swear words are when you really need them!
What makes a word offensive is also very interesting. “The two main categories of swear words are bodily functions and religion—and that’s not just in English, it’s observed across many languages,” says Dr Robbie Love, lecturer in English Language at Aston University in Birmingham. “It’s like the brain has encoded these words with a special meaning so that it knows they are different in some way. I think there’s almost an innate human need to have some linguistic items that can be used to process intense moments.”
Generally though, we’re swearing less than we used to. Dr Love’s research found the use of 16 common swear words has declined by 27 percent over the last 20 years. According to a survey by the British Board of Film Classification, only 12 percent of those aged 55-64 swear regularly compared to 46 percent of 20-somethings. “It’s possible that as we get older we might have fewer uses for swearing. We don’t need it to bond with coworkers. Also, older adults have often had to spend some time restraining their language around children—no matter how our own feelings about swearing change, we still don’t want to expose children to it,” says Dr Love.

5 . Electrically powered vertical-take-off-and-landing (eVTOL) aircraft—flying cars are an idea whose time has not quite yet come, but is fast approaching. Many firms are offering various designs. None of these, however, will be Jetson-like family flying cars. Pivotal, based in Silicon Valley, by contrast has crafted something that people can purchase and pilot themselves. Helix is a single-seat vehicle, so “flying motorbike” might be more accurate. From next year, many people will be able to order one for personal use, though they will not be able to take delivery until June.
Marcus Leng founded Pivotal in 2011, and some back-of-the-envelope calculations he made suggested that electric lift-off of a human-carrying craft, using motors powered by the lithium-ion batteries ought to work. He thus built a model and flew it in the garden of his house in Warkworth, Ontario.
Now, after ameliorating it, the firm thinks it has something marketable. The aircraft has, nevertheless, changed little in its fundamentals over the years. It has two pairs of wings and eight propellers (螺旋桨), making it slightly resemble a squashed “H” when seen in the sky from below. And there is no undercarriage. Instead, its belly is curved in a way similar to a humpback whale’s, so it rocks to stability after landing.
Pilot’s licence or not, buyers will still need some training to fly a Helix. Pivotal insists on this. For the same reason, the craft’s software will stop the pilot doing anything that does not fit its safety rules. And if, despite this, something does go wrong, it is fitted with a parachute（降落伞）.
The Helix’s top speed is a respectable 100 kph, but its range is only 30 km. And refueling it is a bit of a pain. Filling up from the mains takes four and a half hours, though a special high-power system similar to those employed for electric cars can bring that down to 75 minutes. While Helix still doesn’t compare to the flying car from the Jetsons, it could be a step forward.
1. What can we learn from the first two paragraphs?| A．Helix has been used in Warkworth widely. |

6 . On July 28, I retired from my position. After teaching for many years, I looked forward to kayaking (划独木舟) with my grandsons, seeing friends and traveling for leisure with my husband. But my body had other plans for me. A broken spine (脊椎) in my back took me down a path that upended my plans.
I have long had back pain. However, I pushed through the pain to do my work, which worsened my condition. Doctors urged an operation when increased disability meant I could not sit, stand or walk for a long time. But I wanted to see whether physical therapy (治疗) could create an easier option.
Indeed, hard work with a great physical therapist has let me improve my mobility, sitting and standing. But X-rays told a different story. My spine was unstable and bending. After careful consideration and a second opinion from another professional, I agreed to surgery yet in the near term. Needless to say, the past months have been tough and the way ahead will be even tougher. Kayaking with my grandsons in the peacefulness of the lake is all out of reach, for now.
When I met my physical therapist for the first time, I was a mess. He listened to me outline my history with tears and then calmly said, “You have to make friends with your body.” I have repeated that line to myself daily and worked to embrace my body. I have focused on gratitude. I’m grateful that I do not have a fatal disease. I’m grateful that the body I have remains alert to the world, loved by family and friends. I’m grateful that I am still myself.
I don’t know exactly how the future will play out. The surgeon assures me that I should be able to get in my kayak by summer. But I may have to make friends with a different body, one that is mine regardless of the shape.

8 . In a world where technology is king, hardly does a day go by without the launch of some “world-changing” product in the field of alternate reality.
Many people confuse augmented reality (AR) with virtual reality (VR) and understandably so. Both AR and VR offer alternate or altered reality experiences and as a result, it is easy for users to be attracted and wonder what is real and what is not.
However, AR and VR can be quite different in many ways. The main difference lies in the mode of delivery. Simply put, VR “transports” the user to another world, by “replacing” the real world with a virtual substitute most commonly done through helmets or goggles to completely immerse the gamer in a different reality.
AR, however, does not change the entire landscape of what users see.
VR and AR are both powerful technologies which are still relatively new to many consumers.
| A．VR can be interactive or non-interactive. |
| B．In fact, it adds to reality with digital images. |
| C．In short, at the heart of VR and AR are two very similar technologies. |
| D．However, they have already begun to shake things up in the gaming world. |
| E．It is also getting increasingly difficult to keep up with the “R”s that have come into existence. |
| F．For example, it can make users feel as if they are falling, thereby igniting fear. |
| G．They would see computer made images as an overlay to what they see in real life. |
9 . It is a practice favored by Lena Dunham, Tom Hanks and Lady Gaga to improve their focus and bring about calmness in an often busy, distracted world. Now researchers have found evidence that frequent meditation (冥想) over several years, may help change human gut (肠道), boost the body’s immune (免疫的) system and reduce the risk of anxiety, depression and heart disease. The findings are published by the British Medical Journal.
Meditation is increasingly used to help treat drug abuse, overwhelming stress, eating disorders and long-lasting pain. But until now it has not been clear whether it could also be able to change the composition of the gut microbiome (微生物组). In an effort to find out, researchers led by the Shanghai Mental Health Centre at the Shanghai Jiao Tong University analyzed the stool (粪便) and blood samples of 37 Tibetan Buddhist monks from three temples and 19 residents in the neighboring areas. The Tibetan meditation from the ancient Indian medical system, is a form of psychological training. The monks in the study had practiced it for at least 2 hours a day for 3-30 years. Both groups were matched for age, blood pressure, heart rate and diet. Stool sample analysis revealed significant differences in the diversity and volume of microbes between the monks and their neighbors. “Bacteria enriched in the meditation group had a positive effect on human physical and mental health,” the researchers wrote. “This changed gut microbiome composition could improve immune function in the body.” Blood sample analysis also revealed the levels of markers associated with risk of heart disease were significantly lower in the monks.
The researchers emphasized that the study was observational and the number joining was small, all male and living at high altitude, making it difficult to draw any firm or general conclusions. However, based on their findings, the researchers said the role of meditation in helping to prevent or treat mental and physical illness deserved further research.

10 . A man with advanced Parkinson’s disease (帕金森氏症) is now able to walk almost normally again thanks to electrodes implanted (电极植入) in his spinal cord (脊椎), researchers said on Monday. The medical first was achieved by Swiss researchers who had previously pioneered similar breakthroughs to help disabled people walk again.
“This could be a game-changing technology to help bring back movement in people with advanced Parkinson’s,” said David Dexter, research director at Parkinson’s UK.
Marc Gauthier, the 62-year-old patient who lives in France, has suffered from the brain disorder for about 30 years. Like more than 90 percent of people with advanced Parkinson’s, Mar c has had great difficulty walking. What are known as “freezing” experiences — during which patients are unable to move for a limited time, putting them at risk of falling — are particularly awful, Marc told AFP.
Much remains unknown about Parkinson’s disease, making treatment difficult. But the disease can seriously affect the lives of patients, sometimes keeping them to bed or a wheelchair. So when the opportunity came to go through an operation in Switzerland, Marc gladly accepted the chance.
“Now I can do whatever I want,” Marc says. “I can go for a walk and go out shopping by myself.” He adds that he can now walk much more easily — he is even planning a trip to Brazil — but it still requires concentration, particularly when climbing upstairs.
The Swiss team, led by surgeon Jocelyne Bloch and neuroscientist Gregoire Courtine , implanted a complex system of electrodes called a “neuroprosthesis (神经假体)” at important points along Marc’s spinal cord. The neuroprosthesis was first tested on animals, and then implanted in Marc, who has used it for roughly eight hours a day over nearly two years.
The Swiss team has expanded their experiment to a group of six Parkinson’s patients, aiming to know how it could help others, given the disease affects people in different ways. However, treatment using the implant could be quite expensive, potentially limiting how many patients would have access.
