The Signal is Out There. We Just Have to be Ready
"It’s not crazy," Bill Nye tells us, that we could hear radio signals from other civilizations.
Add two more planets to the small but growing list of candidates that might host intelligent life in the universe. Kepler-62 is a sun-like star some 12,000 light years away in the constellation Lyra. Within the Kepler-62 system are two planets that fall within the so-called "Goldilocks Zone," or "the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water," NASA reports.
Of course, scientists do not know whether life does exist on these newfound planets or others, but according to Bill Nye, aka, the Science Guy, there is only one way to find out. We need to open our ears and listen. "It’s not crazy," Nye tells us, that we could hear radio signals from other civilizations. "Perhaps there is another civilization not intentionally trying to get hold of us but sending out signals," he says.

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.
