[2022·昆明市“三诊一模”教学质量检测]Pandas are famously picky eaters. They only consume bamboo—a poor quality diet low in fat. But the creatures appear to have evolved to get the most out of what they do eat, according to a new study.
Their gut (肠道) bacteria change in late spring and early summer when bamboo is at its most nutritious time—when proteinrich green shoots are coming out. The bacteria make the panda gain more weight and store more fat, which rearchers said may compensate for a lack of nutrients later in the year, when bamboo plants have only fibrous leaves to chew.
“We've known the pandas have a different t of gut microbiota during the shooteating ason for a long time, and it's very obvious that they are chubbierdim是什么意思 during this time of the year，” said lead study author Guangping Huang, a rearcher for the Institute of Zoology at the Chine Academy of Sciences.
To investigate how the gut bacteria could affect a panda's digestion, the team first collected the wastes of eight wild giant pandas in China's Qinling Mountains during both the leafeating ason and shooteating ason and then examined how the waste samples differed. They found a bacterium called Clostridium butyricum was more abundant in the pandas' guts during the ason when they enjoy the fresh bamboo shoots.
To understand whether this bacterium helps the pandas gain and store weight, the rearchers put the panda wastes they collected into lab mice. Then they fed the mice for three weeks with a bamboobad diet that simulated what pandas eat. Rearchers found the mice which were transplanted with panda wastes collected during the shooteati
ng ason gained significantly more weight than the ones which were not, despite consuming the same amount of food.
“The gut bacteria were the only variable (变量) in this rearch，” Wei explained. However, Felix Sommer at the ChristianAlbrecht University of Kiel in Germany, noted the number of pandas studied was small and that the experiment had only been performed once. Sommer also stresd the rearchers had found a link, not a causal relationship between the bacteria and weight gain.

展会英语翻译Although computer technology is often necessary today, using a pen or a pencil activates more areas of your brain than a keyboard does. You can potentially remember more by handwriting, according to a new study.
The potential benefits of handwriting for memory have been debated for some time. The new study was carried out to answer one question: How does handwriting compare to using a keyboard when it comes to remembering new information?
在职医学硕士In all, 24 participants took part. Rearchers asked each of them to write with a pen and then each was also asked to type on a keyboard. While performing the tasks, each volunteer wore a cap that held electrodes next to their head. It looked somewhat like a hairnet equipped with 256 nsors. Tho nsors recorded the participants' brainwaves. The electrodes noted which parts of the brain were turned on during each task. And they showed that writing turned on the memory area in the brain while typing didn't.幼儿英语培训班
merchantjapanevideos中文tmAudrey van der Meer, the new study's leader, says this suggests that when we write by hand, we remember better. “This is becau writing involves complex movements that activate more areas of the brain. The incread brain activity gives the brain more ‘hooks’ to hang on to your memories，” she explains. Audrey van der Meer also points out that writing by hand is related to visual notetaking. “Rather than typing blindly, the visual notetaker has to think about what is important to write down. Then, key words can be interlinked by boxes, arrows and small drawings，” she adds.
This study does not recommend banning digital devices. In fact, its authors point out that computers and other devices with keyboards have become necessary in modern society. Keyboarding can especially benefit tho with certain special needs (such as if they have trouble using their hands) and typing beats writing when it comes to speed, they add.
