3-D Printing: End of Our Throw-Away Culture?
Advancements in 3D printing technology are revolutionizing consumption and manufacturing. Instead of throwing broken items away, fix them by printing a croudsourced spare part!
What's the Latest Development?
Recent advances in 3D printing technology have made commercial-quality printers affordable to the public for the first time. And the design software needed to create objects has become more user friendly. Instead of throwing away a coffeemaker, for example, because its knob is broken, simply design a new one or croudsource one that has been created by the online 3D printing community. If the trend continues, manufacturing will one day turn on specialized products designed by people in your local community.
What's the Big Idea?
The concept of 3D printing, originally known as rapid prototyping by companies that could afford the once-exclusive technology, allows individuals to design and manufacture their own products. Today, small and medium size companies can make quick and inexpensive prototypes, test them and scale production if desired. Manufacturing material is also undergoing a revolution as 3D hardware makers search for ways to use recycled household plastics as the printers' "paper and ink".

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.
