Michio Kaku on Lucid Dreaming
The renowned physicist and scholar discusses the science of lucid dreaming, from his Big Think interview posted earlier this week.
"There’s some superstition called lucid dreaming where you can actually control the direction of the dream. Well that superstition last year became science fact. At the Max Planck Institute in Germany they were able to show once and for all that lucid dreaming is testable, reproducible – it is real. They took a person who was about to go to sleep and told them that when you dream clench your right fist and then clench your left fist. Now when you dream you are paralyzed. You cannot move... When this person went into a dream state you can clearly see that the brain initiated orders to clench your right fist and your left fist... in other words, he was conscious while he was dreaming."
From Michio Kaku's recent Big Think interview, a clip from which you can watch below:
Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."
- Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
- Patients from low-income neighborhoods are most at risk of negative health impacts.
- Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.
The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.
- The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
- Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
- Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
We explore the history of blood types and how they are classified to find out what makes the Rh-null type important to science and dangerous for those who live with it.
- Fewer than 50 people worldwide have 'golden blood' — or Rh-null.
- Blood is considered Rh-null if it lacks all of the 61 possible antigens in the Rh system.
- It's also very dangerous to live with this blood type, as so few people have it.
An innovation may lead to lifelike evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
