Core Viewpoint - The continuous rainfall in the Huanghuaihai region, particularly in Henan and Shandong, has led to increased risks of mold growth on corn, causing delays in harvesting and raising public concerns about the quality of corn in the market [1][2]. Group 1: Mold Risks and Detection - Corn in humid environments may develop various molds, but not all are harmful; toxic molds can be effectively controlled through professional methods [1]. - The presence of toxic molds requires specific conditions, and not all infected corn will exceed toxin limits [1]. - A three-step method to identify bad corn includes: 1. Visual inspection for color and texture changes 2. Smelling for musty or sour odors 3. Tactile examination for stickiness or powdery texture [1]. Group 2: Public Assurance and Quality Control - The corn currently being harvested in the Huanghuaihai region is primarily feed corn, which is different from fresh corn consumed by the public [2]. - Feed corn undergoes multiple inspections before entering production, ensuring that only compliant corn is used for livestock feed, alleviating public concerns [2]. - Consumers can safely consume fresh corn purchased through regular channels, as the risk of mold has been effectively managed with ongoing harvesting and drying operations [2].

研究中甚至捕捉到了两种奇特的"模式"：翻滚模式中，章鱼把身体缩成一团，后腕足在身下像传送带一 样依次推动，滚着前进，仿佛在海底打滚。"踩高跷"模式中，它会将后腕足笔直向下延伸，像撑杆一样 把整个身体抬离海底，然后一步步"走"起来。 最近，一项发表于《科学报告》的最新研究给出了答案：章鱼能让任意腕足完成任何任务，且还会"分 工"，用特定的腕足干特定的活。这听起来或许不稀奇，但在无脊椎动物中，这种被称为"功能特化"的 行为极为罕见，一般是灵长类动物专属。 这种八爪分工的策略，可能是章鱼在进化中形成的高效生存密码——前腕足和后腕足互不干扰，各司其 职，实现感知与行动既完美分离又高效协同，在深海的寂静舞台上，演绎出无脊椎生命中顶尖的智能与 优雅。 在深海，有一种生物被认为是海洋中智者的化身。它没有骨骼，却能灵活地攀爬、挖掘、伪装，甚 至还会"踩高跷"走路。它就是章鱼，动物界最令人惊叹的"多任务处理大师"。 数据显示，前面四条腕足的使用率高达64%，而后四条只占36%。这种偏好并非随机——前腕足更像 是"手"，常被用来探索环境、触摸物体、搜寻猎物；而后腕足则更像是"脚"，更多承担起移动身体的重 任。 长期以来，科学家一 ...

随着天气转凉，季节性过敏进入高发期，不少"过敏星人"出现眼睛红肿、打喷嚏、皮肤瘙痒等症 状。与此同时，网络上"益生菌能抗过敏"的说法热传，电商平台上主打"调节免疫力""改善过敏体 质"的"抗过敏"益生菌销量节节攀升。这类产品价格从几十元到数百元不等，部分甚至宣称"7天改善鼻 敏""3天改善肠道"。 那么，益生菌能否通过类似或其他方式抗过敏？ 胡启文认为，从理论层面来看，某些特定的益生菌菌株或许可以通过调节人体免疫系统、改善肠道 屏障功能等方式，间接发挥一定的抗过敏作用。"肠道是人体重要的免疫器官，肠道菌群平衡与免疫系 统正常运转密切相关，这是益生菌可能与过敏产生关联的核心逻辑。"他说。 不过，从实际研究来看，益生菌抗过敏机制尚未完全阐明，且缺乏足够的循证医学支持。陆军军医 大学基础医学院教授王莉表示，近年来，尽管针对益生菌与过敏的研究不断增多，但由于益生菌种类繁 多、过敏性疾病类型复杂、个体差异显著，相关研究结果并不一致。 王莉举例说，有的研究显示某些益生菌可以降低过敏性鼻炎患者打喷嚏的频率，但也有多项对照试 验表明益生菌对过敏症状的缓解作用微乎其微，且即使有效果，也需要长期服用才能显现，远非商家宣 称的"3 ...

近期，河南、山东等黄淮海地区受持续阴雨影响，累计降雨量较常年明显偏多，导致玉米收割延 迟、田间滞留时间增加，霉菌滋生风险随之上升。"市场上的玉米会不会发霉？如何发现坏玉米？"不少 网友在社交平台提问。针对公众关心的问题，科技日报记者日前采访了相关专家。 "玉米在潮湿环境中可能滋生多种霉菌，但它们并非都有害，且有毒霉菌的污染可通过专业手段有 效控制。"农业农村部环境保护科研监测所研究员姚彦坡介绍，比如色二孢穗腐霉菌，它虽会导致玉米 籽粒变色、品质下降，但不会产生毒素。部分黑孢菌、枝孢菌也属于此类。 第一是看一看。正常玉米颗粒饱满、颜色鲜亮，发霉玉米可能有霉斑，颜色发暗、发灰，甚至出现 绿、黑、白等霉点，有的还会粘连在一起。第二是闻一闻。新鲜玉米有自然的谷物清香，发霉玉米会有 霉味、酸味，甚至发苦的味道。第三是摸一摸。正常玉米干燥爽手，发霉玉米可能发黏，有的还会有粉 末感。 "不过，大家不必过于担心。当前黄淮海地区集中收割的玉米，大多属于饲料用玉米，与日常公众 食用的鲜食玉米分属不同品类。"姚彦坡进一步说，这些饲料用玉米在进入生产环节前，会经过多道检 测。只有符合标准的玉米，才能用于家禽家畜饲料生产，公众无需因此 ...
