On August 21, 2017, millions of Americans witnessed the first total solar eclipse to cross the continental United States in 99 years. As in all total solar eclipses, the moon blocked the sun and revealed its ethereal outer atmosphere – its corona – in a wondrous celestial spectacle. While hordes of citizens flocked to the eclipse’s path of totality, scientists, too, staked out spots for a very different reason: to investigate the secrets of the sun’s elusive atmosphere. During the eclipse’s precious seconds of darkness, they gathered new clues on how our sun works, how it can produce deadly solar storms, and why its atmosphere is so hot.

    • 太陽的想像




      As clean and inexhaustible as solar energy is, it only represents less than 2% of global power generation. To make better use of this resource, some engineers are trying to put solar panels on the ground, instead of the roofs. Does it work? Some others try to fly to the sky and sail around the world; some even melt the sand and turn it into glass products and construction materials – all depending on just the power of the sun.

    • 夢中見




      It is one of the big mysteries of humanity: almost every night we dream, but why? Are dreams a window into our unconsciousness or a rational product of our sleeping brain? Why do some of us have nightmares, or even recurring nightmares? Now, a simple but effective way has been found to rid people of nightmares. What is this cure?

    • AI:一切從深度學習開始




      Deep Learning is a radical and recent revolution from engineering. It allows artificial intelligence to better analyse and interpret large volumes of data. Now, AI has already out-performed humans in many applications. The next step would be equipping AI with a consciousness and a general understanding of the world. But, would the development of full AI spell the end of human race, as Stephen Hawking predicted?

    • 狂沙風暴




      Dam-building projects along with other human behavior are contributing to the problem of desertification and a consequent increase in dust storms. This documentary, which was filmed partly in the Middle East, one of the regions worst affected by dust storms, reveals the causes and effects of this natural phenomenon. We will also see how vast clouds of Saharan dust blow across the Atlantic and affect Florida’s coral reefs; and how can scientists predict dust storms with a supercomputer, and help farmers to farm in dry areas.

    • 鐵甲奇心

      38歲時,艾馬‧史班克(Elmar Sprink)的心跳突然停止,經醫生搶救後轉送深切治療部,後來接受心臟移植,重獲新生。不過移植心臟一般只可以運作十年,於是艾馬努力訓練,希望透過運動延長期限。術後一年,他已能參加鐵人賽。新的心臟附近亦長出新的神經細胞,而這個現象從未在成人心臟移植者身上出現。本集除了記錄艾馬頑強求生的故事,亦會訪問優秀的心臟科專家與科學家,探究現今治療嚴重心臟病的新方法,以及醫學技術未來的發展。


      At the age of 38 Elmar Sprink's heart suddenly stopped. Resuscitation, intensive care unit and the life-saving heart transplant. On average, a heart transplant beats for 10 years. Elmar is making every effort to extend this period. He trained hard and took part in an IRONMAN competition merely one year after the surgery. A medical sensation: New nerve cells grow around the foreign organ - a phenomenon that has never been observed in an adult heart recipient. The film combines the emotional story of Elmar’s survival with the search for promising scientific methods. Leading cardiac specialists and scientists will show how treatment methods for severe cardiac diseases are currently developing and what medical advances can be expected in the near future.

    • 深海巨獸




      The NHK team follows marine biologists as they venture into the deep sea of the Antarctic. The team will embark on the world's first scientific research by a submersible in the Antarctic. The dive in the Southern Ocean reveals a surprising world of bountiful marine life, where many creatures are gigantic forms of their shallow-water-dwelling relatives. A hostile, inaccessible world locked away under ice and snow now permits us the first vivid glimpse of its long concealed secrets.

    • 火山歷險(二)

      尼亞穆拉吉拉火山是世上最活躍的火山之一,同時也孕育了豐富的自然資源,包括山地大猩猩和礦物。不過,這亦引來武裝部隊匿藏在火山旁的樹林中,伺機奪取資源,甚至造成人命傷亡。為免受到襲擊,一班火山學家將乘坐直升機抵達火山口邊緣,以預測它下次爆發的時間。另一方面,山德‧托尼根醫生(Dr Xand van Tulleken)會去探訪當地的居民,看看他們如何與火山共處,而且善用它賜予的資源。


      Nyamuragira is one of the most active volcanoes on the planet. It also creates abundant natural resources, like mountain gorillas and minerals. But this attracts armed groups hiding in the forests on the slopes, scrambling for resources and leading to blood and death. To avoid being hit, the volcanologists have to travel on a helicopter to get to the crater rim, in order to predict when the volcano will next erupt. Meanwhile, Dr Xand van Tulleken meets the locals most affected by the volcano, to see how they cope with the constant threat and make the most out of it.

    • 火山歷險(一)



      In Africa lies Nyiragongo, one of the most dangerous volcanoes in the world, as it has erupted twice in the last 50 years, threatening the one million people who live nearby. Now, scientists are climbing up to the crater rim and then descend into the crater itself - to discover the warning signs that it is building towards a new eruption, so they can alert the people in advance. They will work with gas-sampling equipment, thermal cameras and infrasound to try and predict when the volcano will next erupt. Can the team complete the mission successfully and safely?
