法媒:破译达·芬奇DNA密码
Huan Qiu Shi Bao· 2026-01-14 22:51
法国《费加罗报》 1 月 9 日文章,原题:碳 -14 测年、 Y 染色体 …… 破译 " 达 · 芬奇 DNA 密码 " 最近十年来, 参与"莱昂纳多·达·芬奇DNA项目(LVDP)"的美国、意大利科研人员一直在寻找这位天才艺术家的 DNA。近日,他们在达·芬奇的画作上发现了DNA,试图以此验证法国昂布瓦斯达·芬奇墓中的那具遗骸 是否为达·芬奇本人。达·芬奇的陵墓在历史上长期是一个谜。他1519年去世时,曾安葬在法国中部昂布 瓦斯城堡的圣于贝尔礼拜堂内,然而礼拜堂后来遭到严重损毁,藏有达·芬奇遗骸的铅棺下落不明。直 到多年后,人们才在一棵樱桃树下挖到铅棺,棺材内骸骨的身高、牙齿、姿态,似乎都印证这就是达· 芬奇本人。1863年这具遗骸被送往巴黎进行分析,之后铅棺又被带回昂布瓦斯,1876年与新墓碑重新安 葬在圣于贝尔礼拜堂内,之后"达·芬奇之墓"就再也没打开过。 但百年来,人们一直存疑:失而复得铅棺里的那具遗骸,真的是达·芬奇吗?如何采用最新科技来确认 其身份,也就成了LVDP团队的研究课题之一。LVDP团队并没有申请"开馆验尸",而是倾向于通过多种 间接线索和途径,建立达·芬奇的参考基因图谱。不久前,研究 ...

西班牙媒体:研究发现,格陵兰冰盖曾于7000年前完全消融
Huan Qiu Shi Bao· 2026-01-14 22:51
研究团队通过极端环境下的钻探作业,成功获取了埋藏于500多米厚冰层之下的原始沉积物与基岩样 本。运用光释光测年技术,科学家测定这些材料在约6000至8200年前曾长期暴露于地表,证明该区域冰 盖在当时已完全消失。该报告刊发于英国《自然·地球科学》期刊。"这一发现表明,在气候相对温和、 仅比前工业化时期气温高约3至5摄氏度的全新世中期,格陵兰冰盖的关键部分就已变得极其脆弱并彻底 消融,"研究报告主要作者、肯塔基大学的凯莱布·沃尔科特-乔治解释。 数据显示,当时的气温比现在高出3至5摄氏度,恰好落在当前气候模型对本世纪末格陵兰地区的升温预 测范围内。"一些模型表明,到2100年,普拉德霍穹顶区域可能再次达到类似的变暖水平,"沃尔科特- 乔治表示,与缓慢的自然变暖过程不同,当下由人类活动驱动的气候变化速度和强度空前。历史证明, 极地冰盖系统对持续、温和的升温异常敏感,一旦越过某个临界点,消融过程可能变得漫长且难以逆 转。此项研究超越了纯学术价值,直接服务于更精准的全球风险评估。通过识别如"普拉德霍穹顶"这类 对变暖响应敏感的关键脆弱区,科学家能显著改进海平面上升的预测模型,明确哪些沿海城市与地区将 面临最迫切的威胁 ...

施加种种限制,暴露“防华”心态 ,美有条件“放行”H200芯片
Huan Qiu Shi Bao· 2026-01-14 22:45
【环球时报报道 记者 李萌 李嘉钰】美国商务部13日正式批准英伟达向中国销售其第二强大的人工智能 (AI)芯片H200,同时出台一项新规以回应国内对华鹰派的担忧。此前,该芯片因被华盛顿担心会提 升中国在科技和军事领域对美优势而受到限制。14日接受《环球时报》记者采访的专家认为,美国在芯 片问题上采取了"既要又要还要"的思维。从中国角度讲,美国这种心态不可接受。 据路透社报道,根据新规,英伟达H200芯片在运往中国之前必须由第三方测试实验室进行审核,以确 认其AI技术能力。此外,中国客户获得的H200芯片数量不得超过美国客户购买总量的50%。英伟达需 要证明美国境内有足够的H200芯片,中国客户则必须证明拥有"充分的安全措施",而且不得将这些芯 片用于军事用途。 路透社援引股票研究平台Seaport Research分析师杰伊·戈德堡的观点称,美国针对H200的最新出口上限 似乎是一种妥协方案,对英伟达在中国的销售施加了一些限制,但可能难以执行。 英伟达在一份声明中称,美国政府这一决定"达成了一种深思熟虑的平衡,对美国来说是极好的",将帮 助该公司在全球芯片市场中保持竞争力。英伟达发言人还对英国广播公司(BBC ...

【环球时报综合报道】13日,美国众议院通过了"洗澡法案"(Shower ACT),该法案计划放宽联邦政 府对淋浴喷头的流量限制,旨在兑现美国总统特朗普"让美国淋浴再次伟大"的主张。 美联社14日称,美国共和党籍众议员弗莱表示,通过该法案将增大淋浴喷头的水流量,"消费者应该有 自由选择权,无论是涓涓细流的喷头,还是水流大到能把橙子切片的喷嘴"。共和党籍众议员迈克尔·鲁 利则称,通过该法案是共和党"关心工薪阶层"的体现。民主党方面警告称,放宽对淋浴喷头的限制可能 导致消费者水电费用激增。环保组织则批评该法案可能加剧对环境的破坏,浪费水资源的同时会消耗更 多能源。 据英国广播公司此前报道,2025年4月,特朗普签署行政令要求立即废除对淋浴喷头、洗衣机等家用设 备的节水限制。他抱怨说:"我需要站在水流下15分钟才能打湿我的'秀发'。"白宫强调:"新行政令能使 美国家庭摆脱来自官僚主义的过度监管,淋浴喷头将不再软弱无力。" 该法案的具体细节尚未得到披露,在美国参议院的前景亦不明朗。(线一凡) 这场"淋浴喷头之争"可以追溯到1992年美国通过的一项能源法,其规定是淋浴喷头每分钟出水量不得超 过9.5升。特朗普在第一任期时 ...
