一 | 当勒布朗·詹姆斯脱下紫金战袍穿上费城球衣，当“希腊怪兽”空降迈阿密海滩，当北境之王伦纳德时隔七年重返多伦多——2026年的NBA东部，已经不是过去记忆中的东部了。

二 | 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.。

三 | 美媒BGN Hoops盘点了东部球队今夏的阵容变动，那份名单长到让人窒息。76人记者Tony Jones甚至感叹：“这或许是30年来东部最强的一次。”从费城到克利夫兰，从迈阿密到多伦多，九支球队在这个夏天完成了脱胎换骨。东部，从来没有这么挤过。 76人是这个休赛期最大的赢家。他们先是用一笔5换1的交易，送出保罗·乔治和选秀权，从凯尔特人换回了正值巅峰的杰伦·布朗。这笔交易，直接为后续的超级签约埋下了伏笔。随后，勒布朗·詹姆斯以一份2年800万的底薪合同空降费城。一个41岁的老将，放弃了4875万美元的年薪，只为了在生涯末期再搏一冠。76人瞬间凑齐了詹姆斯、布朗、恩比德、马克西的四巨头阵容。一个拥有历史得分王、五届全明星、常规赛MVP和全明星后卫的球队——这不是“补强”，这是“开挂”。骑士是今夏操作最精妙、也最狠的球队。他们明白，光靠哈登和米切尔的后场双枪，永远跨不过尼克斯和76人的锋线群。于是，他们策划了一笔涉及五支球队的超级大交易。骑士送出了斯特鲁斯、特雷·曼恩、2031年首轮签和2032年次轮签，先签后换得到了掘金的锋线新星佩顿·沃特森。沃特森随即签下一份4年8800万的合同。上赛季他场均14.6分4.9篮板，三分命中率高达41.1%。骑士用一份合理的价格，锁定了未来四年锋线的答案。

四 | 再加上哈登最终以3年9700万续约留队，骑士凑齐了哈登+米切尔+沃特森+莫布利+阿伦的攻防一体阵容。ESPN给骑士的休赛期操作评级为A-。迈阿密热火是另一支完成“质变”的球队。他们先是通过交易得到了两届MVP扬尼斯·阿德托昆博，与阿德巴约组成了可能是联盟最恐怖的防守前场组合。随后，热火整个夏天都在等待一个人——克莱·汤普森。8月22日，克莱与独行侠达成买断，放弃了最后一年1750万美元的薪水。热火立即用预留的约890万美元中产特例，将这位四届总冠军射手带到了迈阿密。热火组成了米切尔+克莱+维金斯+字母哥+阿德巴约的超级阵容。字母哥的突破撕开防线，克莱在外线等着接球投篮。字母哥这辈子，可能从没打过这么富裕的仗。多伦多猛龙在这个夏天做了一件充满情怀的事——迎回他们的“北境之王”。猛龙送出布兰登·英格拉姆、格雷迪·迪克、两个首轮签、一个首轮互换权和两个次轮签，从快船换回了科怀·伦纳德。
