珊瑚礁保护意识周

盛开的柱状珊瑚、绿色的海龟和五颜六色的珊瑚鱼，欢迎来到珊瑚礁这个欣欣向荣的水下世界。从7月15日到21日，珊瑚礁保护意识周是向他们致敬的最佳时机。珊瑚礁是由被称为珊瑚虫的微小海洋生物形成的，珊瑚虫创造了巨大的群落，为各种海洋物种提供了家园。当我们把注意力转向它们的美丽和益处的同时，认识到潜在的威胁（气候变化、污染和有害的人类活动）也至关重要。

今天的照片展示的是印度洋海面下的天堂马约特岛。这座法属岛屿拥有世界上最大、最深的泻湖之一，周围环绕着近100英里长的珊瑚礁。马约特岛的泻湖是250多种珊瑚和3500多种海洋物种的家园。但它正面临着众多威胁，包括过度捕捞和珊瑚白化（即珊瑚体内的共生藻离开或死亡，珊瑚就会变白，最终因失去营养供应而死）。因此，本周让我们共同承诺保护这些美丽的珊瑚礁！轻轻潜入水下，因为一滴水花都能惊扰到这些生灵。

Coral Reef Awareness Week

Blooming pillar corals, green sea turtles, and colorful reef fishes—welcome to the underwater universe of coral reefs. They are formed by tiny marine organisms called coral polyps, which create vast colonies housing many species. As we celebrate their beauty and benefits, it's vital to recognize the lurking threats of climate change, pollution, and harmful human activities.

This underwater scene was photographed at Mayotte, a French island region in the Indian Ocean. Mayotte boasts one of the world's largest and deepest lagoons, encircled by a coral reef nearly 100 miles long. It is home to over 250 species of coral and more than 3,500 marine species. But it is facing numerous threats, including overfishing and coral bleaching, where corals expel the algae that live in their tissues, leading to a loss of color and essential energy sources. So, in Coral Reef Awareness Week, let's pledge to preserve coral reefs like this one.

Brain coral

You needn't be a genius to guess how brain coral got its name. But you could just as easily call it 'maze coral' after its labyrinthine surface. Either way, this sea organism is an apt mascot for today's cerebral celebration: Puzzle Day!

From mazes to math problems to minute mysteries, you can find puzzles to tease just about every part of your brain, from the logical left hemisphere to the creative and crafty right. While medical science hasn't fully established that regular practice with puzzles benefits the brain, it's thought that solving puzzles helps concentration, pattern recognition, and memory. Or maybe they're just fun—but hey, that's excuse enough to riddle away the day on your favorite puzzles. Try starting off with today's homepage quiz.

脑珊瑚

你不必是个天才就能猜出brain coral是如何得名的。但你也可以简单地用迷宫般的表面来称呼它为“迷宫珊瑚”。不管怎样，这种海洋生物都是今天大脑庆祝活动的吉祥物：拼图日！

从迷宫到数学问题，再到微小的谜题，你可以找到谜题来挑逗你大脑的每一个部分，从逻辑的左半球到创造性和狡猾的右半球。虽然医学尚未完全证实经常练习拼图对大脑有益，但人们认为解决拼图有助于集中注意力、模式识别和记忆。或者也许它们只是好玩，但嘿，这足以让你在你最喜欢的谜题上度过这一天。试着从今天的主页测试开始。
