5 . Engineers at Deakin University have developed a new smart generation schoolbag that will end the days when students end up forgetting their homework, particularly since the smart schoolbag is capable of completing its own morning checklist.

According to a recent press release, the smart schoolbag comes with built-in hardware and software that works to ensure it is packed correctly for each day’s timetable, including lunch and sports equipment.

The bag was designed by Dr Hamid Abdi alongside Masters students at Deakin University. It uses Radio Frequency Identification (RFID) tags (标签) to detect items in the bag and Internet of Things (IOT) technology, which extends Internet connectivity to everyday objects. “RFID technology allows any user to detect items in the bag in a contactless way,” Dr Abdi says. The Internet of Things (IOT) technology is employed to check its contents against the daily school plan. Schools or parents can enter data about the activities of each day to the system’s IOT server. The server then links these activities to the RFID tags placed on the items needed. The smart school-bag can tell what items are not required, ensuring that the bag is no heavier than it needs to be.

The smart schoolbag will save a lot of time and stress that occurs when homework, hats or lunches are left home by mistake, especially if that requires parents to quickly race home to collect the missing item.

While the system can be fitted to any schoolbag, the team have designed a sample of the smart schoolbag that includes the smartphone application. Dr Abdi and his team are looking for commercial partners to take the project to the next level.

6 . In a weightless, microgravity environment like space, how can someone with sight or mobility problems navigate in the space station? As scientists continue to push the boundaries of spaceflight and the possibility of human life on other planets, how can we build space infrastructure (基础设施) friendly to all humans？

The Mission AstroAccess project aims to answer these questions, starting with a historic parabolic (抛物线的) flight that took off from Long Bench on Oct. 17, 2021. A group of 12 disabled scientists, students, athletes and artists launched into a zero-gravity environment as a first step. To get a better idea of what is needed for more inclusive (包容的) space travel, AstroAccess plans to conduct a series of follow-on parabolic flights after the first launch. On these flights, a plane flies up to an altitude of around 32, 000 feet and then begins a descent at about 4 miles per second. This quick descent creates a microgravity, weightless effect lasting roughly 30 seconds. Afterwards, the plane climbs back up to a stable altitude, and repeats the process again.

The 12 AstroAccess Ambassadors selected for this first microgravity flight included four blind or low-vision Ambassadors; two deaf or hard-of-hearing Ambassadors；and six with mobility disabilities, all carrying out various tasks in the weightless environment. One of the challenges was seeing whether all members could perform basic safety and operational tasks. The crew also tested whether sound beacons (声信标) could be used for blind members to direst themselves, They are also investigating how American Sign Language will be impacted by microgravity.

“My whole career goal is to make the average person able to go to cuter space, where you don’t have to be a crazy trained astronaut with perfect physical abilities and health to visit cuter space,” said Brenda Williamson, head of the AstroAccess logistics committee. “I grew up on Star Trek, so the idea of exploration is really important.”

7 . Jerry was born on October 14, 1966. Shortly after birth, he was discovered to have a heart defect (缺陷) and quickly had an operation to save his life. Although he always thought his childhood to be “normal”, there were quite a few things that made him a little different. He couldn’t do heavy farm work like his brothers and his classmates called him “grape juice” because his lips would turn purple in gym class.

After another operation, Jerry went on to live a very full life. He studied in a technical school and met his love after graduation. They married in 1989, and in 1993, the first light of Jerry’s life was born.

Growing up with Jerry as my dad was the greatest blessing of my life. He was always full of life and light, making anyone around smile. He never wanted to draw attention to his medical condition. Even many of his close friends and co-workers were unaware of his heart problem. To all of us he was just a normal guy — that was just the way he wanted it.

I didn’t know or understand my father was sick until he was placed a pacemaker (心脏起搏器). Despite several times of unconsciousness, and 19 days’ stay in ICU, he managed to celebrate Christmas with us and even work as usual. With his wide laugh, I soon adjusted to a “new normal” father. The progress and life, as we now know, came to a grinding halt one night after he came down with a cold.

He was picked up by a helicopter. The nurse said my dad was in good spirits throughout the trip, cracking jokes and making her laugh. When he was unloaded, his eyes rolled back and was unresponsive. The man who loved his life and family was gone.

My dad taught me many lessons. But probably the most important one was in his death. I know as I celebrate his incredible life, he will be looking down on me with smile.

8 . Fleanor Love knows that weddings create a lot of leftover flowers. That means more opportunities for her to collect after-wedding bouquets (花束) and give them to her lonely hospital _______, many of whom don’t often have visitors, let alone expensive _______.

The flowers are still in good shape, and the patients are pleased to have them. “I was so _______ that I cried,” said patient Connie Melzer, who was recovering from a heart problem when Love walked into her room with a bouquet in early 2020.

Love worked at the Virginia Commonwealth University Hospital as a(n) _______ student. She wondered how she could help _______ the patients’ suffering besides learning how to treat them as a student doctor.

“One of the _______ of being a medical student is that it can be very difficult to _______ to the care team,” said Love. “You are there as a learner, who doesn’t have as much knowledge as doctors. But you want to _______ your patients. How can I at this stage in my training make a(n) _______ for them?”

In 2019, she started The Simple Sunflower in Richmond, and so far has ________ more than 760 bouquets to patients. She brought fellow students and other people into her project, and now has more than 200 ________ on the email list.

When Love began the project, she called businesses such as wedding venues (场馆) and florists and asked them what events were scheduled. She then reached out to brides and grooms to ask them if they had ________ for their flowers after the big day.

For each wedding, she organized a team of eight people who helped ________ the flowers when the party was over and then spent time carrying them to individual patients.

People beyond the VCU community have heard about Love’s project and become part of it. “Once the word got out, people around the city started ________ us,” Love said. She wanted to bring the project to more cities and maybe open branches at other medical schools.

“I feel ________ when I see the patients who receive our bouquets,” she said. “It reminds me why we do what we do.”

10 . The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia in later life, and as they did, it came on a decade later than less sporty women.

Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said : "These findings are exciting because it’s possible that improving people's cardiovascular （心血管的）fitness in middle age could delay or even prevent them from developing dementia. "

For the study, 191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak （最大值的） cardiovascular capacity. The average peak workload was measured at 103 watts.

A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.

These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.

"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important. " She also admitted that a relatively small number of women were studied, all of whom were form Sweden, so the results might not be applicable to other groups.
