布朗大学经济学教授怀疑班级里多数学生使用 AI 作弊
在去年 12 月学校发生枪击案之后,布朗大学经济学教授 Roberto Serrano 首次让学生在家中完成期中考试。期中考试成绩显示大部分学生获得了满分或接近满分,他怀疑学生大规模使用 AI 作弊。因此决定将期末考试改为线下进行。他没有立即宣布期中考试无效,而是决定先看看期末考试的得分。如果期末考试得分的分布与期中考试的分布基本相同,那么他会将期中考试得分计入成绩。结果是 18 名学生退课,9 名学生没有参加期末考试。3 名学生得了零分,期末考试的平均分只有 48.6%——这是他所教班级迄今的历史最低分。此前期末考试的平均分从未低于 65%。只有少数学生的期末考试成绩与期中考试的成绩相近。 via Solidot

相对论支配重元素化学键
布朗大学化学家提供了直接证据,证明重元素三键的传统解释需要修正。化学教科书称,原子通过共享电子形成化学键。每个原子共享一个电子形成成键电子对。电子对的强负电荷吸引着两个带正电的原子核,从而将它们结合在一起。一些元素会共享多个电子对,形成双键或三键。三键由一个σ键两个π键组成。σ键是头碰头的强键,π键是弱键,环绕在σ键周围。这种描述适用于轻元素。当原子核足够重时,爱因斯坦相对论会改变三键的结构,模糊了σ键和π键之间的界限。光电子能谱显示,碳-铋键不符合传统的一个σ键和两个π键构成的三键结构。其结构更像是由一个π键和两个σ-π杂化键构成。 via Solidot

中国法院支持数字资产的继承
多个案例显示中国法院支持数字资产的继承。法院认为游戏账户和微交易购买属于某种货币价值,因此玩家对这些资产拥有相关权利。法院拒绝标准的不可转让条款,认为这些条款无法阻止你继承或转让游戏(包括微交易物品)。其中一个案例是一位玩家的遗孀试图继承《征途》中的一把“黄金刀”。死者的游戏“情侣”对此表示反对,因为黄金刀是一件只能通过两个玩家协作游戏获取的道具,两个玩家的账户被连结为游戏中的情侣。法院发现另一名玩家曾出价人民币 5 万元购买黄金刀,表明该武器具有真正的市场价值。法院还注意到两名玩家在获取黄金刀上投入了大量的时间、精力和资金。因此法院认为黄金刀构成具有经济价值的虚拟财产,能成为死者遗产的一部分。然而由于它是由死者和游戏“情侣”共同获取的,法院最终得出结论:所有权由他们共同享有。因此只有死者的份额(50%)可以由他的继承人继承,而剩余的份额归游戏中的“情侣”。第二个案例涉及到了 5 个比特币和一个价值约 20 万元人民币的游戏账户。 via Solidot

GLP-1 减肥药并不能取代锻炼
GLP-1 减肥药并不能取代锻炼。研究人员跟踪了 130 名重度肥胖患者一年,他们平均减重 13.7公斤。研究人员将他们分成四组——运动组、服用 GLP-1 药 liraglutide 组,运动加 liraglutide 组,以及安慰剂组。研究结果显示,运动组的血管更健康,炎症水平也更低。虽然只服用 GLP-1 药有助于减轻体重,但不能改善血管健康。动脉壁越厚,动脉粥样硬化、血栓和中风的风险越大。运动组的动脉壁厚度减少了 6-7%,但服用 GLP-1 药和安慰剂组没有改善。运动组的炎症标志物水平也下降了。运动组的参与者平均每周训练约两个半小时,主要是健身车和循环训练。 via Solidot
