Rewiring the Brain: Deep Brain Stimulation and the Future of Happiness | Gods Like Us (2/3)

After several family members developed Alzheimer's disease, Julia Ravey decided to become a neuroscientist and find the cure. Following recent research that suggests a link between the stomach, the brain and mental health, she meets the scientists harnessing the power of what is called "The Microbiome". Julia travels to Australia, where she meets Dr. Barry Marshall, a Nobel-prize winner who infected himself with H. pylori to prove that bacteria could cause ulcers, leading to a breakthrough in the stomach cancer treatment. However, bacteria are not all bad – in the Netherlands, she visits the Micropia Museum, learning that microbes can also be essential to our way of life. Understanding the microbiome as a kind of ecosystem that is part of the human body, scientists are attempting to increase the presence of microbes across the body by intentionally infecting people with more infectious agents. As microbiologists from Rutgers University explain to Julia, increasing microbial diversity in the body boosts its immunity, and helps people fight disease from the inside out. The next stop is UC San Diego, home to The American

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.

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

Elsewhere, a motorcyclist is brought in following a serious road traffic collision as trauma teams search for hidden internal injuries. From split-second decisions to life-saving treatment, witness the extraordinary work of frontline emergency nurses inside one of the UK's busiest emergency departments.

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
