    • January 29, 2012
    • NHK

    One in three Japanese people will die of cancer, so it's no surprise that cancer research is one of the most important medical fields. Currently, there are three established treatments: surgery, chemotherapy and radiation therapy. But today scientists around the world are working to add a fourth: cancer vaccines. And Japanese researchers are right in the thick of it! They are identifying genes that are expressed only in cancer cells, and making vaccines from molecules called peptides that form from the breakdown of the proteins these "cancer genes" encode. We hear about patients who were treated with the vaccine-and saw amazing results. And in the studio, we have Yusuke Nakamura of the University of Tokyo Institute of Medical Science, one of Japan's leading researchers in this field.

  • S2012E13 New Frontiers in Seismic Design

    • April 12, 2012
    • NHK

    Do you know what the most significant source of damage is to a building during an earthquake? While most people might think of the magnitude and intensity scales as a way to measure a quake's destructiveness, there is actually another important factor: an earthquake's period of oscillation. For example, during earthquakes with a long period of oscillation, tall buildings are most susceptible to damage because of a phenomenon called resonance. Studies have now begun to analyze the kind of ground cities are built upon in an effort to predict the period of earthquakes before they happen. We report on this cutting edge research protect buildings against giant earthquakes.

    • January 24, 2013
    • NHK

    A huge number of toxins exist all around the world. And believe it or not, the nine deadliest toxins come from living things! Tetrodotoxin, found in the organs of blowfish, is particularly notorious. When blowfish is prepared for consumption in Japan, it must be prepared by a licensed chef who is trained to cut the toxic organs out. It is possible, however, under special conditions, to raise blowfish that are not toxic at all. In fact, blowfish aren't even born with the poison at all. So, where does it come from? Scientists are looking for ways to use biotoxins for medicinal purposes. For example, conotoxin, which paralyzes nerves, could be a thousand times more effective than a certain drug you may have heard of. Can you guess what it is? Join us as we step into the deep and amazing world of biotoxins.

The National Museum of Nature and Science, Tokyo has a history of more than 130 years. In addition to its valuable exhibits in the fields of natural history and the history of science and technology, it also engages in pioneering research. The new natural history building in Tsukuba, which houses most of more than 4 million items in the natural history collection, was completed in April 2012. You can see fascinating items not normally shown to the public, as we explore the natural world of Japan, how the Japanese people interact with it, and also Japan's growth as a technological power. In Part One, we focus on the fauna of Japan. Our first port of call is the ancient specimen collection, where we examine a fossil that is considered one of Japan's treasures. What makes this 6 plus-meter long plesiosaur, discovered in 1968, such a national treasure? Well, it actually helped overturn a widely held assumption about Japanese natural history. Tune in to find out what it was. Meanwhile, a fossil found nearby suggested that our futabasaurus was engaged in a ferocious battle with another creature. What was this creature, who helps inspire vivid images of an ancient Japanese ecosystem? We peer into the scientists' toolkit to see how CT scanning is now being used to study the structure of such valuable fossils - without breaking them! CT scans have also revealed much about the way of life of an ancient mammal known as the "mysterious beast!"

Ice particles inside the clouds rubbing against each other generate a large amount of static electricity, which in turn leads to extraordinary lightning called Superbolts with more than 1,000 times the energy of ordinary lightning. Dr. Teruaki ENOTO of RIKEN discovered that a phenomenon called "annihilation" occurs in these Superbolts, emitting enormous amounts of energy, and this has attracted worldwide attention. Annihilation is a phenomenon that is thought to have occurred in the formation of the universe, causing matter and antimatter to disappear in a burst of light. The study of annihilation in Superbolts is now providing clues about the beginning of our universe.

    • February 15, 2022

    With the spread of COVID-19, as well as the declining birthrate and aging population in Japan, the shortage of blood has become an important issue. As the number of blood donors decreases, it will become more difficult in the future to secure blood for transfusion. Recognizing this risk, Professor Teruyuki Komatsu of Chuo University's Faculty of Science and Engineering is working on the development of artificial blood that can be administered to anyone at any time. He has succeeded in developing an artificial oxygen carrier by extracting hemoglobin from red blood cells and encasing it in a protein called albumin. Moreover, Professor Komatsu's artificial blood does not have a blood type and eliminates the need for compatibility tests, a key advantage for immediate transfusion in an emergency. Animal experiments have already confirmed its effectiveness in stabilizing blood pressure during hemorrhage and treating strokes, and he is now focusing on the possibility of applying it to humans.

  • S2022E03 Protecting Infrastructure by Visualizing Stress

    • February 22, 2022

    Both in Japan and other developed countries, social infrastructure built during periods of rapid economic growth is rapidly aging, and accidents involving aging infrastructure are becoming more frequent. The useful life of infrastructure is considered to be about 50 years due to the deterioration of concrete, a key component. Concrete eventually cracks due to internal chemical reactions and external forces, and so-called "moving cracks" that are gradually progressing due to the constant application of force are particularly dangerous. However, finding such cracks is a difficult task that requires significant time and effort. That's why Nao Terasaki, a team leader at the National Institute of Advanced Industrial Science and Technology (AIST), and his colleagues have developed a luminescent material that helps reveal dangerous cracks by making them glow. The technology is called "stress luminescence," which generates faint light at locations inside an object where force is concentrated.

  • S2022E06 The Mystery of the Dying Bamboo

    • April 5, 2022

    For the first time in nearly 120 years, "hachiku" bamboo is flowering all across Japan. The hachiku bamboo plant expands by sending out underground stems, which can grow at a rate of about 2 meters per year. The plant then essentially creates clones of itself by sending up shoots from these stems. Yet once every 120 years, the hachiku bloom, leave seeds and die off en masse. Why has this type of bamboo developed such an unusual flowering cycle? First, researchers ran simulations on the evolutionary process of bamboo based on observational data. Analysis of the results has yielded clues into bamboo's incredible survival strategy. We'll also look at rare footage of hachiku bamboo flowering, and see how a new material made from bamboo could change space development.

    • April 25, 2023

    Anger, sadness, joy... How do these various human emotions arise? The latest brain research has revealed a surprisingly close relationship between emotions and our bodies. When the body's condition changes, such as when the heart beats faster or blood pressure rises, this information is sent to the "insular cortex" in the brain. We now know that the changes in the body sensed by the insular cortex are recognized as emotions born within us. Moreover, the ability to recognize these changes in the body varies from person to person, and this affects the amount of "empathy" one has for other people's emotions. Research has also shown that people who have difficulty in recognizing their own emotions are insensitive to changes in their bodies, which can aggravate chronic pain.

This is a promising new solution to energy and environmental problems as it can efficiently produce hydrogen and other substances. Japan was one of the first countries to recognize this technology and had launched a national project that involved the collaboration among industry, academia, and government. In 2021, they successfully produced large amounts of hydrogen, taking the world by surprise. Also in this episode, take a look at a system that can power homes using carbon dioxide. Find out the latest in artificial photosynthesis with reporter Michelle YAMAMOTO.

  • S2023E16 Poisons in the Animal Kingdom

    • October 10, 2023

    There are many dangerous creatures in the natural world that use poison for self-defense or for hunting, such as poisonous snakes, spiders and scorpions. It is said that there are more than 200,000 species of poisonous animal on Earth, each with varying degrees of toxicity. Research is currently underway around the world to make these animal poisons useful to humans. For example, a major feature of biotoxins is that they target particular molecules. This "specificity" can produce different results on different targets. This feature is being applied in the development of drugs with minimal side effects and pesticides that only attack pests. Researchers explore the possibilities of a "treasure trove" of poisons. [J-Innovators] Using a distinctive optical design to create a "touchless" touch-panel display.

And yet, they have ways of processing information. This ancient "intelligence" is of particular interest for unprecedented experiments by Japanese researchers that surprisingly showed slime molds could solve mazes. Moreover, a new type of computer is in the works that applies the information processing abilities of slime molds. The latest research looks into the mysteries of the evolution of life. This episode thoroughly dissects the mysterious powers hidden in the single-celled body of slime molds. [J-Innovators] Certified space food! Dried fish that can be eaten bones and all.

  • S2023E18 Next Generation Solar Cells

    • November 14, 2023

    Solar power generation is attracting attention as a way to solve energy problems. However, conventional silicon-based solar cells have one particular weakness - their power generation efficiency depends on the weather. This is why the world is now focusing on the development of perovskite solar cells as "next-generation solar cells." Perovskite solar cells can not only generate electricity on cloudy or rainy days, but even under weak indoor light as well, all while being lightweight and easy to make! Now competition to develop these cells for practical use is intensifying around the globe. In this episode, we examine how the innovative technology was created by Japanese researchers, and the incredible potential perovskite solar cells hold for the future.

  • S2023E19 Great Escape: How Prey Avoid Predators

    • November 28, 2023

    All over the planet, creatures display incredible ways to escape predators. Shocking escape techniques beyond imagination are still being discovered one after another. A juvenile eel escapes from the gills of a predator fish even after being eaten. A bombardier beetle ejects gas that can reach temperatures of up to 100℃ to fend off an attack by a praying mantis. The common Japanese idiom "a frog stared at by a snake," implying a frog so overcome with fear that it can't move, actually belies a profound survival strategy. Even playing dead has been shown to be advantageous in avoiding predators. In this episode, we'll look at how "predation avoidance behavior" is tied to creatures' fundamental desire to survive.
