Is Voice Communication Over?
With AT&T announcing its free mobile to mobile calls to help fend off customers defecting for the iPhone on Verizon’s network, it’s time to recognize that voice is now worthless.
Because voice is still profitable and represents a sizable chunk of operators’ revenue, operators won’t let it go without trying to recoup some of that average revenue per user with higher data charges for consumers. They’ll also turn to machine-to-machine subscriptions to make up profits and provide high-volume, lower-revenue subscriptions. I explained a lot of this last May, but today’s news is yet another data point showcasing the continuing decline of voice. Sure it’s good for those who use their phones for talking over cell networks, but thanks to VoIP, video chat, and increasing web use, that source of income is overrated.
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.

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.
