Study: ‘6G’ Radiation Boosts Brain Cell Growth in Mice_我的网站

康熙王朝

一 |     The same technology that may power the next generation of mobile networks has been shown to increase the growth of brain cells in mice, according to a new study from Xian Jiaotong University in Beijing.,Radio waves in the terahertz frequency can transmit data at speeds up to 1 terabit (or 125 gigabytes) per second, it is a prime candidate for the next generation of mobile cell phone networks if it can be proven safe. By contrast, current 5G networks use millimeter waves that top out at 20 gigabits (2.5 gigabytes) per second.,But there may be another use for terahertz radio waves: treatment of neurological disorders like Alzheimer’s disease, autism, and Parkinson’s disease.,Science & Tech'Vicious Cycle' Between Alzheimer's Dementia and Daytime Napping Found by Scientists17 March, 19:05 GMT,The researchers exposed mice neurons in a petri dish to 100-microwatt pulse radiation, ranging from 0.3 terahertz to 3 terahertz. The result was that the exposed neurons grew at a rate of 150% compared to the control group. The length of connections also doubled in three days. Despite the accelerated growth, the brain cells appeared healthy.,The accelerated brain growth was not permanent; it slowed two days after exposure.,However, a 2009 study by the Russian Academy of Sciences showed that prolonged exposure to strong terahertz radiation had an adverse effect, increasing the temperature of brain cells, disturbing their development and causing dehydration of the cells which reduces their size and causes other damage.,But Li Xiaoli, the lead scientist of the new Beijing study, thinks that the negative effects of terahertz radiation could be avoided by limiting the strength and duration of exposure.,“The safety of terahertz radiation protocol is a top concern,” Li said. And while the health concerns of terahertz radiation remain, it could, Li believes, be used to treat neurological disorders.,“Abnormal neuron development and the resulting abnormal neural network structure can lead to the occurrence of various psychiatric and neurological diseases, such as Alzheimer’s disease, autism and Parkinson’s disease,” the study’s authors said.,The authors believe that a lower dose of terahertz radiation could increase the production and the activity of certain proteins responsible for brain cell growth, namely GluA1, GluN1, and SY-38. The researchers theorize that is because they contain hydrogen bonds that constantly vibrate at a frequency that falls in the terahertz range. The radio waves combine with the proteins and cause them to resonate in a “non-linear manner,” according to Li, which could “affect the shape of the proteins, and therefore the structure and function of neurons.”However, because proteins vary significantly from each other, only certain proteins are affected by the terahertz radiation at low frequencies. Li says more investigation is needed to learn how proteins react to different exposure intensities.,The study backs up another done at the Institute of Brain Science at Xian Jiaotong University that was published in June. That study found that terahertz exposure could make young mice more intelligent. There, scientists exposed mice to 90-milliwatt terahertz radiation for 20 minutes a day for three weeks. They observed that the exposed mice had more brain cells and were quicker at escaping mazes. However, for reasons that remain unclear, the same effect was not observed in older mice.。    巳蛇嬉嬉,          童游非遗中国年!                    第十八站:泉城新春烟火气                                                                                                                                   趵突泉边的红灯笼刚挂上树梢,芙蓉街的青石板已漫起糖瓜的甜香。当曲水亭街的老茶碗续上第七道泉水,济南这座城市便瞬间被浓郁的年味所笼罩着,让我们一起来到童游非遗中国年的第十八站-济南,感受春节济南的魅力!                                                                                                                                                                                                                                                                              剪一片月光,把祝福贴在窗上                     小剪刀,咔嚓嚓,剪只福虎墙上挂!"济南剪纸艺术是国家级非遗,老艺人能用一张红纸剪出泉城柳、荷花鲤,连趵突泉的三股水都跃然纸上。         济南剪纸          春          节                              面团里的魔法剧场                     济南过年有个超厉害的习俗——面塑,它可是国家级非遗!过年时,济南的大街小巷都能看到面塑摊。师傅用彩色面团,三两下就能捏出可爱造型。面塑不仅好看,还带着吉祥寓意。                                                                                                                                                                                                                                                                   鼓点里的千年心跳           "咚咚锵!"当章丘芯子的娃娃们扮成哪吒踩着高架巡游,当商河鼓子秧歌的伞、鼓、棒划出欢快的弧线,这就是济南人血脉里的春节BGM!这些国家级非遗项目,用最热闹的方式讲述着黄河岸边的故事。快带宝贝去看社火表演,让他们跟着鼓点扭起来吧!          章丘芯子          鼓子秧歌          舌尖上的非遗地图           在芙蓉街的老巷里,糖画艺人手腕轻转就画出会飞的糖凤凰;把子肉在百年老汤里咕嘟作响;杨氏茶汤的龙嘴大铜壶扬起一道琥珀色的弧线…带孩子用舌尖丈量济南非遗美食地图,让老味道成为童年最甜的春节记忆。         糖画                              把子肉           – SPRING FESTIVAL –                    茶          汤                    SPRING          FESTIVAL                                                                                                                                                       这个春节,我们和孩子们踏上了一段奇妙的"寻找年味之旅"!从北方窗花剪纸的魔法剪刀,到南方醒狮的威风步伐;从热气腾腾的团圆饺子,到甜甜蜜蜜的八宝年糕……每一场非遗邂逅都是时光馈赠的成长礼物,让孩子们用指尖触摸文化温度,用舌尖跳跃家乡滋味。          让我们共同呵护这些在童年生根的文化嫩芽,期待每个孩子都能成为最棒的"小小传承人",让带着祖辈温度的年俗故事,继续在他们未来的人生里绽放光彩!                              中二班的小朋友来给大家拜年了                    撰稿 | 唐妙红          编辑 | 陈健彬          审稿 | 唐妙红          审核 | 于美华。
