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.

    • 救救森林




      In regions that are prone to wildfires, such as the areas around the Mediterranean Basin, the fight to save species is underway. After the ravages of the flames, programmes aimed at reforestation and reintroduction of animal species are being conducted by biologists, agronomists and environmental specialists. How are they reforesting entire woods and also making them more fireproof? To protect biodiversity, scientists are assessing wildfires’ impact on local animals. Some insects take advantage of the disasters and spread in burnt forests. Some other creatures lose their habitats after the fires, like the endangered Iberian lynx. Can scientists save them from a bigger crisis?

    • 水源修復




      Water is at the heart of life itself and of biodiversity.  If it is polluted or there is a shortage of water, then many ecosystems will come under threat. The environmental disaster in Brazil in November 2015, caused by the failure of a mining dam, devastated not only the species along the rivers, but might also pose a threat to the sea turtles that laid eggs on the beaches nearby. Associations and volunteers have been attempting to repair the immense damage done to the environment. In Africa, it is beset with water shortage. Therefore, many countries are now committed to an impossible mission: building a forest on the edge of the desert to help combat droughts. Can the scientists fix the water and rescue its ecosystems?

    • 第一個美洲人




      One unlucky day 13,000 years ago, a malnourished teenager missed her footing and tumbled to the bottom of a 100-foot pit deep inside a cave in Mexico’s Yucatán. Rising seas flooded the cave and cut it off from the outside world—until a team of divers chanced upon her nearly complete skeleton in 2007. Intricate detective work reveals that the young woman’s bones are among the earliest known human remains in the Americas. What drove her to venture nearly a mile underground inside a vast cave? Where did her people come from, and why would she look so distinct from today’s Native Americans? From a stunning Mexico cave to the genetics lab, new clues are being discovered, rewriting the story of the forgotten first people who ventured into the Americas.

    • 蟲蟲大搜查




      Welcome to the biome inside your home: a world of insects and spiders as rich, as surprising, and as beautiful as any other ecosystem. Every corner is a potential lair, every carpet a dense forest, and the wide spaces of your kitchen, an open savannah where food is abundant. Many creatures will be safe and sound in your home. But if you decide to set them free outside, you may in fact be dooming them to death in a world they have never known. Entomologists will investigate what they really are, how they have adapted to live with us, and how our lives intersect.

    • 隱形殺手之超級細菌



      Hundreds of thousands of people die annually, due to multi-resistant germs - bacteria, which are no longer challenged by the use of many antibiotics. Experts and politicians from all corners of the world warn of the looming catastrophe: multi-resistant pathogens are currently the most major risk faced by modern medicine. Millions of people will die without effective antibiotics, of illnesses that have long been considered eradicated. This documentary shows however, that of all people, it is the manufacturers of vital medication that contribute to the development and global propagation of extremely resistant germs and that not even their own resources have any effect on them.

    • 幽靈血管




      99% of human blood vessels are said to be capillaries. With age, these tiny tubules break, becoming hollow "ghost" vessels that cause wrinkles in the skin. Scientists are now finding they are also tied to a higher risk of age-related ailments, including osteoporosis and Alzheimer's disease. Using advanced biological imaging techniques, this program delves into the mechanism behind broken capillaries. It also examines how to slow down or even repair the damage to help people live longer, healthier lives.

    • 大地的想像



      The earth nurtures everything. Not only is food harvested from the soil, power can also be generated by our land - more specifically, by the thermal energy in it; even bacteria of plants can do the trick. Some other scientists are recently using land to turn CO2 into rocks. In Romania, an underground salt mine is turned into a recreational space, in which the salty air is said to be beneficial to our health. What other unexpected uses does the earth have?

    • 風的想像



      We all know what wind power is, but do you know typhoons could generate power too? It is estimated that the energy of typhoons, if harnessed, could provide electricity for half of the world. But first we would need wind turbines that would not be destroyed by strong winds. Engineers are designing turbines without blades – how does that work? Some others are trying to turn balloons into a means of transporting goods and conducting scientific research. What are the other possibilities that lie in the movement of air?

    • 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?
