Last Day on Earth: A Tribute to Mothers

Introduction
The bond that exists between a mother and her child is one of the purest, most enduring connections known to humanity. It is a relationship built on love, sacrifice, and unwavering support. In the hit mobile game "Last Day on Earth," the role of the mother figure holds a special significance. This article aims to explore the importance of the "mama" character in the game and pay tribute to all the real-life mothers who embody her qualities.

Body
1. The Nurturer: A Mother's Love
In "Last Day on Earth," the mama character embodies the essence of a nurturing and caring mother. She provides a safe haven, a place where players can find solace amidst the chaos of a post-apocalyptic world. She cooks nutritious meals for her children, stitches wounds with tender care, and offers words of encouragement when hope seems lost. Similarly, real-life mothers are the epitome of unconditional love and support. They selflessly devote themselves to their children, always putting their welfare above their own. A mother's love is a constant presence, providing the emotional foundation necessary to thrive in both good times and bad.

2. The Protector: Strength in the Face of Adversity
In "Last Day on Earth," the mama character often faces dangerous situations head-on to ensure the safety of her children. She fights zombies and other threats fearlessly, demonstrating her unwavering determination to protect those she holds dear. Real-life mothers, too, possess an unmatched strength when it comes to protecting their children. They are the staunchest defenders, ready to face any challenge or sacrifice their own well-being to shield their little ones from harm. A mother's protective instinct is an unbreakable force that creates a sense of security, teaching their children to rise above any adversity they may encounter.

3. The Teacher: Empowering the Next Generation
The mama character in "Last Day on Earth" takes on the role of an educator, imparting valuable knowledge and skills to help her children survive and thrive. She teaches them how to hunt, fish, and gather resources effectively. She equips them with essential life skills to navigate a world forever changed by disaster. In the real world, mothers are often a child's first teacher. They instill important values, impart wisdom, and provide guidance to help their children become well-rounded individuals. A mother's teachings are not limited to school subjects but extend into the realms of compassion, empathy, and resilience, shaping their children into future leaders.

Conclusion
In a world filled with uncertainty and chaos, a mother's love remains a constant beacon of hope and strength. "Last Day on Earth" captures this sentiment through its portrayal of the mama character, who personifies the nurturing, protective, and teaching qualities that make mothers so exceptional. This game serves as a reminder of the invaluable role played by mothers in our lives. Let us honor and cherish the mothers who have molded us into the individuals we are today, for they are the ones who have helped us survive and thrive on the last day on Earth.

　　央视网消息：从2021年天和核心舱发射升空到现在，三年时间，中国空间站已展开近百项空间科学实验，取得一批重要科研成果。此次神舟十八号乘组也将在轨开展多项科学实验。

　　作为国家级太空实验室，中国空间站的科学研究设施主要包括密封舱内的14个科学实验柜、舱外暴露实验平台等，支持在轨滚动实施空间天文、空间生命科学与生物技术、微重力基础物理等科学研究。

　　中国科学院空间应用工程与技术中心研究员张伟称：“我们之前大概做了近一百项实验，有四十多个实验的样品已经返回，产出了一些有特色的成果。”

　　本次随神舟十八进入中国空间站的实验项目包括生命生态科学实验、材料舱外暴露实验等4项科学实验项目。其中，生命生态科学实验项目把斑马鱼和金鱼藻作为研究对象，“太空养鱼”将有望在中国空间站实现。

　　斑马鱼是一种非常漂亮的观赏鱼，大概3—4厘米长，体形纤细，从头到尾有多条深蓝色的纹路，如同斑马一样，所以被称为斑马鱼。这次上天的太空鱼缸里配备有4条斑马鱼，还有金鱼藻，鱼缸是密闭的，装满了水，斑马鱼需要的氧气全部由金鱼藻的光合作用产生，系统可以实现自动喂食、温度控制、光照控制等，还可以收集鱼卵，将来由航天员带回地面，供科学家进行进一步研究。

　　作为一种典型的模式实验动物，斑马鱼与人类基因组有超过70%的相似性，这也是迄今为止中国空间站除了航天员以外迎来的首种脊椎动物。

　　张伟称：“斑马鱼和金鱼藻形成一个小型生态，同时斑马鱼还是一个非常小的脊椎动物，我们要研究脊椎动物在太空的骨丢失，做肌肉萎缩的研究，形成一个系列化的研究。”

　　据介绍，通过2023年的广泛征集，中国空间站征集到近千个科学项目，遴选出100余项，正在分批立项，预计分别通过天舟八号、九号和十号飞船上行实施。

　　张伟介绍：“目前比较有意思的，我们将要上小鼠，这些小老鼠要在上面进行饲养，然后把它返回。返回以后要进行大量的研究，包括骨丢失、肌肉萎缩，包括免疫力、神经，相当于全方位对小鼠进行一些研究。通过对小鼠深入的研究，实际上对未来人在太空的长期生存非常有意义。”
