On blazing hot summer days, fresh ingredients and cool refreshments straight from a refrigerator feel like nothing short of a miracle. However, chilled foods didn’t begin with modern refrigerators. In fact, the origin of refrigeration precedes the invention of this now-indispensable appliance by centuries.
Initially, the quest for refrigeration was motivated more by the desire to cool beverages than to preserve food. The ancient Greeks and Romans, for instance, used snow stored in insulated pits to chill wine. Around the fourth century BC, the Persians made a significant stride in refrigeration techniques when they devised the yakhchal. Fashioned from thick mud-brick walls, these innovative dome-shaped structures preserved ice and consequently food in a primitive yet effective manner.
It wasn’t until the 17th century that refrigeration took another leap forward with the development of the icehouse. Equipped with a system to drain meltwater, this underground chamber could keep ice frozen for up to 18 months. By the 18th century, icehouses were a prized feature that was part of many wealthy estates and villas in the UK.

The popularity of icehouses ushered in a golden age of commercial ice trading in the 19th century. Initiated by American merchant Frederic Tudor in 1806, this lucrative trade demanded extensive labor for the purpose of harvesting, transporting, and selling ice. This industry boomed in North America and Norway in particular. During the peak of the ice trade in the 1890s, Norway exported a staggering 250,000 tons of ice a year.
What followed, however, is hardly a surprise to us now: the introduction of the electric refrigerator in the early 20th century spelled the end of the ice trade. As we rely on the convenience of modern refrigeration today, let’s not forget to appreciate the history of the innovations that came before this marvel of modern life.
在炎炎夏日裡，直接從冰箱拿出的新鮮食材和清涼茶點簡直就彷彿奇蹟。然而，冷藏食物的起點並非現代冰箱。事實上，冷藏的起源比起這項現在不可或缺的家電的發明時間還早了好幾個世紀。
最初，人們對冷藏的追求更多是受到想要冷卻飲料，而不是想要保存食物的動機所驅使。例如，古希臘人和古羅馬人使用存放在隔熱地窖中的雪來冷卻葡萄酒。公元前四世紀左右，波斯人發明了冰塔，在冷藏技術上取得了重大進展。這些創新的圓頂結構體是由厚重的泥磚牆所砌成，以原始但有效的方式保存了冰塊，從而也保存了食物。
直到西元17世紀，隨著冰窖的發展，冷藏技術才再次出現了飛躍。這個配備了融水排放系統的地下室可以將冰塊保持冷凍長達18個月。到了西元18世紀，冰窖成為英國許多富裕莊園和別墅的一大珍貴特點。
冰窖的流行迎來了西元19世紀商業性冰貿易的黃金時代。這項利潤豐厚的貿易由美國商人弗雷德里克．都鐸在西元1806年發起，需要大量勞動力來進行冰塊的採集、運輸和銷售。這個行業在北美和挪威尤為蓬勃發展。在西元1890年代冰貿易的鼎盛時期，挪威每年出口的冰塊就達到驚人的25萬噸。
然而，接下來發生的事情對我們現在來說幾乎不足為奇：隨著西元20世紀初電冰箱的推出，這意味著冰貿易的結束。我們如今在依賴現代冷藏的便利時，也別忘了去欣賞在冰箱這項現代生活奇蹟出現前，就有些創新作為存在的這段歷史。

US President Donald Trump has renewed his ambition to take control of Greenland for national security reasons and questioned whether Denmark has any legal right to the Arctic island. The debate has revived scrutiny of how Greenland became part of Denmark, its current self-rule and path to independence, and Washington’s military footprint. HOW DID DENMARK GET GREENLAND? Greenland was inhabited by Inuit peoples from Asia and North America intermittently from around 2,500 BC. Around 985 AD, Vikings led by Erik the Red settled in southern Greenland, farming and building churches. Around the same time, ancestors of today’s Inuit arrived, living as hunters

Owls have long fascinated people with their distinctive appearance and mysterious habits. These nocturnal birds possess large, round eyes and a flat facial disc. Their feathers come in shades of brown, gray, or white, helping them blend easily into the darkness. The most remarkable trait of owls is that they can turn their heads without damaging blood vessels. Contrary to popular belief, they can only rotate their heads up to 270 degrees, not 360 degrees. Owls have 14 cervical vertebrae, which is twice as many as humans. This special physical structure compensates for their inability to move their eyes within their
AI-generated summaries are shaking up the media world. Tools like Google’s AI Overviews now provide users with direct answers above the search results, resulting in fewer people clicking on news links. For publishers who rely on that traffic to generate advertising revenue, this shift is hitting hard. The fallout is measurable. Many sites have seen a sharp drop in traffic since AI summary features rolled out. An analysis revealed that a news outlet that had once ranked first on Google lost up to 79% of its traffic when its link appeared beneath an AI-generated summary. Statistics also show that
