CRISPR 是基因實驗室研發的新工具,可以讓科學家極精準地改變任何生物的遺傳物質。科研人員正在用CRISPR 來研究不治之症的療法,亦有農業公司正在研發出新的植物品種,令它們擁有抗蟲等特質。同時,訂製嬰兒的出現亦變得指日可待。究竟我們應該容許醫學及農業走得多遠?


    CRISPR is a new tool in the gene laboratory which allows scientists to change the genetic material of all living organisms with great precision. Researchers are using CRISPR to develop therapies for incurable diseases. Agriculture companies have created plants with new characteristics, like resistance to pests. Meanwhile, designer babies are suddenly within reach. How far should medicine or agriculture be allowed to go?

    • 解毒大地




      Nuclear accidents severely damage the environment and soil for decades at least. Previously fertile soil and land that once provided a habitat for fauna and flora then become a source of poison.
      But it is not just radioactivity that causes irreparable damage to our lands, intensive farming also causes this slow but sure poisoning. Use of pesticides and toxic fertilisers, the cultivation of plants and crops that are inappropriate for the soil type and, ultimately, damage to the environment and biodiversity are evident in every field!

    • 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.
