Secrets Of The Brain With Jim Al-Khalil

Professor Jim Al-Khalili explores the extraordinary 600-million-year evolution of the human brain. From primitive sea creatures and the first neurons to the rise of mammals and the emergence of imagination, he uncovers the scientific breakthroughs that transformed a simple nervous system into the most complex organ in the known universe.

Discover the secrets behind the Colosseum's epic restoration and the ingenious Roman engineering that keeps this ancient wonder standing after 2,000 years. Take a behind-the-scenes journey through the meticulous process of restoring the Colosseum, Rome's iconic amphitheater. This video reveals how expert conservators and modern industrialists are working together to clean centuries of grime, repair fractures, and ensure the Colosseum remains waterproof and structurally sound. You'll learn how travertine stone, marble powder stucco, and innovative monitoring systems are being used to preserve the monument's legacy for future generations. Explore the fascinating history of the Colosseum's construction, from Emperor Vespasian's vision to the advanced Roman techniques that allowed this massive arena to rise in just ten years. We delve into the practical engineering marvels - like the use of arches, Roman concrete, and elliptical foundations - and uncover how construction was divided among competing companies, resulting in visible joints and unique design quirks. The video also addresses the challenges posed by earthquakes, pollution, and even the vibrations from nearby metro lines, along with the ongoing debate over public-private partnerships funding the

Deep within the isolated volcanic waters of the San Benedicto Island, a massive 20-foot ocean giant defies everything scientists thought they knew about marine life. Once feared as legendary "devil fish," giant manta rays are now known to be peaceful, highly intelligent creatures possessing mammalian-sized brains and a strange, deep curiosity for human contact. This documentary follows world-renowned biologists on a high-stakes expedition to the remote Socorro Archipelago, deploying cutting-edge satellite tracking and harvesting vital DNA samples to protect these majestic animals. However, a dark threat looms as industrial gill netting and illegal poaching push this protected ecosystem to the absolute brink of collapse, making the fight for their survival more urgent than ever.

Can science really help us become fitter, younger, smarter and maybe even more perfect? In this episode of Myth or Science, Dr Jennifer Gardy puts some of the biggest health and human-performance claims to the test. Can exercise reverse aging? Is a few minutes of high-intensity training really as good as a long workout? Can you be fat and fit? Is willpower something you can train like a muscle? And could coffee, cooked food, music, or even sleep change the way our bodies and brains work? From intense lab tests and skin biopsies to MRI scans, DNA analysis, brain challenges, and music therapy after stroke, Jenn dives into the science behind the myths we hear every day. Along the way, she discovers that some “too good to be true” claims are surprisingly real, while others need a little more nuance. ------- Chapters ▷ 00:00 - Intro: Can Science Make Us Better? ▷ 01:27 - Can Exercise Reverse Aging? ▷ 03:47 - The Mice Experiment: Exercise vs. Aging ▷ 05:35 - Skin Biopsy Results: From 70 to 40? ▷ 07:44

In Episode 1 of Myth or Science, microbiologist Dr Jennifer Gardy takes on some of the most common health and science claims we hear every day. Using her own body as part of the experiment, she travels from Florida’s mosquito labs to freezing cold research chambers, New York food tests, and a classroom ice cream challenge to separate fact from fiction. Can mosquitoes really prefer women over men? Does grilled meat increase cancer risk? Does alcohol actually warm you up in cold weather? Do we lose most of our body heat through our head? Can eating too fast make you gain weight? And can brain freeze happen even on a cold day? With humor, curiosity, and unorthodox experiments, Gardy puts each claim under the microscope, revealing the surprising science behind the myths that shape our everyday choices. ------- Chapters ▷ 00:00 - Intro: Are Common Health Claims True? ▷ 00:40 - Can You Spread a Cold Before Symptoms? ▷ 01:51 - Are Mosquitoes More Attracted to Women? ▷ 08:00 - Can Grilled Meat Increase Cancer Risk? ▷ 11:52 - Can

Seven years ago Dr. Norman Doidge introduced Neuroplasticity to the world – the idea that our brains aren’t rigid, that they can change, can be rewired. The Brain’s Way of Healing is about neuroplasticity’s invaluable next step – healing the mind and the body. It’s revolutionary and in some instances shocking – we’ll see people’s lifelong afflictions cured almost miraculously. But miracles have nothing to do with it. It’s about how science and medicine are looking at the brain in different ways and discovering that permanent, lifelong and even life threatening ailments and diseases can now be dealt with–and in many instances done away with. ------- Chapters ▷ 00:00 - Introduction ▷ 01:00 - The man that walked off his parkinsonian symptoms ▷ 08:02 - A device that resets the brain helps two women recover from traumatic brain injuries ▷ 12:30 - The portable neuromodulation stimulator that reverses the symptoms of a muscular sclerosis patient ▷ 20:15 - Using energy and sound waves to help rewire the brain of autistic children ▷ 32:40 - Healing a brain injury with low-intensity
