We criminalize drug addicts in this country. To Nora Volkow, director of the National Institute on Drug Abuse, that would be equivalent to putting someone with Parkinson’s in jail. Drug addiction is a disease that changes the chemistry of your brain, and makes you unable to kick the cravings. It all stems from dopamine, a powerful drug that controls pleasure and leads you to make decisions that aren’t truly benefitting your body.
Volkow walks us through the reasons that different drugs trigger addictions and why certain people are more prone to addiction than others. It’s not only about genetics- nurture plays a key role in making someone vulnerable to the disease.
She also launches into a discussion on the human’s propensity for food addictions, a relationship more complex than that of drugs. Is it possible to transfer a love of chocolate to a desire for lettuce and running? It’s more complicated than you think.
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.
