Do White Holes Exist?

There’s been plenty of research and ample discussion of black holes in our universe–those regions in space where mass is packed so densely that it forms a singularity that not even light can escape. But what about their bizarro twins, their total opposite–white holes. Written off many times by science as a mathematical quirk, white holes remain hypothetical, though the math checks out and the reason to search for them are numerous. Host Julian Huguet takes a deeper look at the conundrum in this episode of Seeker.

Making Blood Type Universal

Accessing the right blood type in a medical emergency can be a matter of life or death. Today, blood types are categorized as A, B, AB and O, each with their own antibodies and antigens. Choosing the wrong type during a transfusion could mean trouble. But physiologist Patrick Kelly says there is hope on the horizon. Using a century of research and medical advancements in recent years, Kelly says scientists are developing a method to advance blood transfusion accessory even more to transform all donated blood to universal donor type. Here’s more from Seeker.

Is Phosphorous the Key to Life?

Scientists have discovered new evidence that one element–phosphorous–could be essential to creating life anywhere in the universe and it could be scarce.

Oxygen, carbon, hydrogen and nitrogen are the so-called bulk elements that make up our muscles and organs, and that we need a lot of to stay alive. But phosphorous is equally as important.

It is the key that provides our genetic make up–DNA and RNA–and our ATP, how we store and use energy. So is life in the universe rarer than we think? Or might there be other alien elements out there creating life we don’t understand? Host Maren Hunsberger explains further in this edition of Seeker.
