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.

4 . 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. |

6 . In recent years American society has become increasingly dependent on its universities to find solutions to its major problems. It is the universities that have been to blame for developing the expertise to place men on the moon; for dealing with our urban problems and with our worsening environment; for developing the means to feed the world’s rapidly increasing population. The effort involved in meeting these demands presents its own problems. In addition, however, this concentration on the creation of new knowledge significantly impinges on the universities’ efforts to perform their other principal functions, the transmission and interpretation of knowledge-the imparting of the heritage of the past and the preparing of the next generation to carry it forward.
With regard to this, perhaps their most traditionally acknowledged task, college and universities today find themselves in a serious situation. On one hand, there is the American commitment, especially since World War Ⅱ, to provide higher education for all young people who can profit from it. The result of the commitment has been a dramatic rise in enrollments(登记入学) in our universities, coupled with a striking shift from the private to the public sector of higher education.
On the other hand, there are serious and continuing limitations on the resources available for higher education. While higher education has become a great ”growth industry“, it is also at the same time a tremendous drain(耗竭) on the resources of the nation. With the vast increase in enrollment and the shift in priorities away from education in state and federal(联邦的) budgets, there is in most of our public institutions a significant decrease in expenses for their students. One crucial aspect of this drain on resources lies in the persistent shortage of trained faculty(全体教师), which has led, in turn, to a declining standard of competence in instruction.
Intensifying these difficulties is, as indicated above, the concern with research, with its increasing claims on resources and the attention of the faculty. In addition, there is a strong tendency for the institutions’ organization and functioning to fulfill the demands of research rather than those of teaching.

When our youngest sister was born, my little brother Tom was six and I was eight. I had always been the “Big Sister” and he had always been “The Baby”.
Our sister’s arrival was a complete surprise to both of us. In those days no one worried much about sibling rivalry (兄弟姐妹间的较劲), and no “experts” told us how to deal with another child in the house. We had wise and loving grandpa and mom, however.
I was excited about the baby and loved to hold her and help care for her. Tom’s feelings were quite different! He just looked at her and left, preferring to spend the evening in his room. When I went to his room to talk to him and try to get him to play games with me, he just looked away. “Why did they have to get that baby?” Tom asked.
Later that night, Grandpa came over to see the new baby. As he held her, he said to Tom, “You know, she’s a lot like the baby lamb I’m raising on the bottle. I have to take care of her and feed her often, just the way your mom does with the baby.” Tom said, “I’d rather have the lamb.”
Grandpa heard and said, “Well, if you’d rather have a lamb, maybe we could trade your little sister for it. I’ll give you a day to think it over, and if you still want to trade tomorrow, we’ll do it.” I thought I saw him wink at Mom, but I knew I must have been mistaken because Grandpa never winked at anyone.
After Grandpa left, Mom read to Tom for a long while. Tom kept looking at the baby, and Mom asked him to hold our little sister while she went to the bathroom. When Mom came back. Tom was gently touching the baby’s smooth black hair, and as he held her hand, she took hold of his finger.

10 . “Given that signs of Alzheimer’s disease (老年痴呆症) start to accumulate in the brain several decades before the disease begins, understanding the connection between sleep and cognition (认知) earlier in life is critical for understanding the role of sleep problems as a risk factor for the disease,” said study author Yue Leng, PhD, of the University of California, San Francisco.
The study involved 526 people with an average age of 40. They were followed for 11 years. Researchers looked at participants’ sleep duration and quality. Participants wore a wrist activity monitor for three continuous days on two occasions approximately one year apart to calculate their averages. Participants slept for an average of six hours. Participants also reported bedtime and wake-up time in a sleep diary and completed a sleep quality survey with scores ranging from 0 to 21. A total of 239 people reported poor sleep with a score greater than five.
Researchers also looked at sleep fragmentation (碎片化), a measure of restlessness during the sleep period expressed as a percentage. The higher the value, the more sleep is interrupted. Participants were divided into three groups based on their sleep fragmentation score. Of the 175 people with the most interrupted sleep, 44 had poor cognitive performance 10 years later, compared to 10 of the 176 people with the least interrupted sleep.
After adjusting for age, sex, race, and education, people who had the most interrupted sleep had more than twice the possibility of having poor cognitive performance when compared to those with the least interrupted sleep. There was no difference in cognitive performance at midlife for those in the middle group compared to the group with the least interrupted sleep.
However, due to the small sample size, the researchers were unable to fully investigate potential race or sex differences. “More research is needed to assess the link between sleep disturbances and cognition at different life stages and to identify if critical life periods exist when sleep is more strongly associated with cognition,” Leng said.
