两栖类动物在冰雪冬季仙境中挑战冰点

研究人员发现,蓝斑蝾螈即使在体液低于正常冰点的情况下仍能保持活跃,这种状态被称为“过冷”。这一现象是在加拿大安大略省阿冈昆省立公园的蝙蝠湖观察到的,当时湖面仍然结冰,地面也被冰覆盖。尽管存在这些极端条件,蝾螈仍被看到在陆地上移动。

根据渥太华大学的研究员大卫·派克博士说,“我们注意到,地面上仍然有冰,湖面仍然结冰,但出于某种奇怪的原因,蓝斑蝾螈出现在了陆地上。”派克和他的团队当时正在进行对蝾螈行为和生理的研究时做出了这一令人惊讶的观察。

蓝斑蝾螈在冰冻温度下生存的能力是一种令人惊叹的适应性,这让科学家们感到困惑。古时候,人们认为蝾螈可以在火中生存,但这是一个误解。然而,一些蝾螈已经进化到能够应对其他极端温度条件,包括冰冷。

派克解释说,蝾螈能够在过冷状态下保持活跃,可能是由于它们独特的生理结构。“它们有一个专门的系统,可以防止体液冻结,”他说。“这是一个复杂的过程,但基本上,它们能够创造一种‘防冻剂’,防止细胞冻结。”

这一发现对我们理解动物生理和适应性有着重要的影响。它也引发了人们对这一知识在医学和生物技术等领域的潜在应用的疑问。“这一研究可能会带来新的见解,告诉我们如何预防或治疗与寒冷相关的伤害和疾病,”派克说。

研究结果引起了科学家和公众的兴趣。蓝斑蝾螈在冰冻温度下生存的能力是地球上生命多样性和适应性的一个令人惊叹的例子。随着研究人员继续研究这一现象,我们可能会揭开更多关于自然世界的迷人秘密。

研究团队计划继续研究蓝斑蝾螈的行为和生理,以更深入地了解它们的非凡适应性。他们希望能够阐明这一现象背后的机制,并探索其潜在的应用。

Lawmaker sues to remove Trump's name from Kennedy Center

A Democratic board member, Representative Joyce Beatty, has filed a lawsuit to remove President Donald Trump's name from the John F. Kennedy Center for the Performing Arts, claiming the renaming was illegal without Congressional approval. The board, dominated by Trump allies, voted to rename the center in his honor, citing his efforts to strengthen the center's finances and modernize its facilities. The lawsuit argues that the center was intended to be a "living memorial" to President Kennedy, and the renaming undermines its original purpose.
