Scientists using an aerial remote-sensing method have discovered the largest and oldest-known structure built by the ancient Maya civilization — a colossal rectangular elevated platform built between 1,000 and 800 BC in Mexico’s Tabasco state.
The structure, unlike the soaring Maya pyramids at cities like Tikal in Guatemala and Palenque in Mexico erected some 1,500 years later, was not built of stone but rather of clay and earth, and likely was used for mass rituals, researchers said on June 3.
Located at a site called Aguada Fenix near the Guatemalan border, the structure measured nearly 400m wide and 1,400m long and stood 10m to 15m high. In total volume, it exceeded ancient Egypt’s Great Pyramid of Giza built 1,500 years earlier.

There were no signs of sculptures depicting high-status individuals, suggesting Maya culture at this early stage was more communal and only later developed social inequality and a hierarchical society led by royalty, the researchers said. “Because it is so large horizontally, if you walk on it, it just looks like natural landscape,” said University of Arizona archaeologist Takeshi Inomata, who led the research published in the journal Nature. “But its form comes out nicely in lidar.”
Lidar, short for Light Detection and Ranging, is a remote-sensing technique that employs a pulsed laser and other data obtained flying over a site to generate three-dimensional information about the shape of surface characteristics. Nine large causeways and a series of reservoirs were linked to the structure. Some parts of the rural Aguada Fenix site today are covered with cattle ranches. Other parts are wooded.
“It is probable that many people from surrounding areas gathered for special occasions, possibly tied to calendrical cycles,” Inomata said. “The rituals probably involved processions along the causeways and within the rectangular plaza. The people also deposited symbolic objects such as jade axes in the center of the plateau.”

科學家日前利用空中遙測技術,發現馬雅古文明迄今所知最大規模、最古老的建築結構。該遺址是一座巨大的長方形高台,位在墨西哥的塔巴斯戈州,建造於西元前一千年到前八百年間。
研究人員六月三日表示,該遺址迥異於馬雅文明一千五百多年後於瓜地馬拉的提卡爾和墨西哥的帕倫克等城市建造的高聳金字塔,並非由巨石堆砌而成,而是用黏土和泥土建成,可能是用來舉行大型祭祀活動。
此建築座落於一處稱為「阿瓜達芬尼克斯」的遺址,靠近瓜地馬拉的邊界,長一千四百公尺、寬幾乎達四百公尺,高度約為十到十五公尺。從總體積來看,此結構超過古埃及早一千五百年(即西元前兩千五百年)建造的吉薩大金字塔。
研究人員指出,這處遺址並未出現刻畫身居高位的個人雕塑,意味著馬雅文化在這個早期階段較為偏向「共治」,直到稍晚才發展出社會不平等的現象,以及由王室主導的階級制社會。美國亞利桑那大學的考古學家豬俁健是研究主持人,他表示:「因為這個結構和地面平行,規模又如此巨大,當人走在上面時,感覺就像是走在自然形成的地理景觀上。」豬俁健進一步補充說:「不過,透過光學雷達,遺址的結構就清楚地展現出來。」這份研究日前刊登於《自然》期刊。
「光達」是「光線檢測與測距」的簡稱,是一種運用脈衝雷射的遙測技術,配合受測地點上空獲得的其它資料,產生地貌特徵的3D資訊。這次發現的大型結構,與九條大型堤道和一系列蓄水設施相連。地處鄉間的阿瓜達芬尼克斯遺址,今日部分地區被養牛的牧場覆蓋,其它部分則被繁茂的樹林遮蔽。
豬俁健表示:「許多來自周圍地區的人,可能會在特殊場合在此聚會,或許和曆法的週期有關。」他進一步推測:「這些儀式可能包括沿著堤道、在矩形廣場內列隊遊行。這些人也會在高台中央放置玉斧這類具有象徵性的物品。」

South Korea’s famous kimchi is falling victim to climate change, with scientists, farmers and manufacturers saying the quality and quantity of the napa cabbage that is pickled to make the ubiquitous dish is suffering due to rising temperatures. Napa cabbage thrives in cooler climates, and is usually planted in mountainous regions where temperatures during the key growing summer season once rarely rose above 25 degrees Celsius. Studies show that warmer weather brought about by climate change is now threatening these crops, so much so that South Korea might not be able to grow napa cabbage one day due to the intensifying heat. “We
It’s widely recognized that there are far more right-handed people than left-handed people in the world. Being right-handed simply means preferring to use one’s right hand for tasks that involve only one hand, such as writing and eating. But have you ever wondered about the possible reasons behind the global dominance of the right hand over the left? As with many complex biological questions, multiple factors appear to be at play. First, one reason seems to be genetics. __1__ Therefore, the global dominance of right-handedness is something that has been passed down through many generations of humans. Next,
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

Historically, items that require physical manipulation have been designed for right-handed use. For example, tools like scissors and musical instruments are often constructed with right-handers in mind, making it difficult for left-handers to use them. __4__ While these factors offer some explanation, they remain speculative. The precise reasons for the global prevalence of right-handed people continue to be debated. Nevertheless, left-handedness will remain a phenomenon of great curiosity among scientists and researchers for many years to come. 最後,文化影響也在人們偏好哪一隻手上扮演一角。歷史上,需要用到肢體操作的物品都被設計來供右手使用。舉例來說,像是剪刀、樂器等工具常常就是考慮到右撇子而打造的,造成左撇子難以使用這些工具。因此,許多天生就是左撇子的人可能就必須透過學習使用右手來適應。 雖然這些因素都提供了一些解釋,但它們仍是推測而已。全球右撇子如此普及,確切的原因仍持續被爭論著。不過,在未來的許多年裡,左撇子依然會是科學家和研究人員相當好奇的一個現象。 What Did You Learn?
