S5 Ep17: Could You Be Immune To Everything?

Do you remember having a cold in 5th grade? Or the flu a couple years ago? Your immune system does. Our bodies hold many levels of immune defense. Millions of B cells and T cells and antibodies are constantly on patrol for germs and antigen invaders. As scientists learn more about how this system works and how to engineer it, could we ever actually be immune to everything?

The Most Interesting Life Forms On Earth And Beyond5m24s

The Most Interesting Life Forms On Earth And Beyond

What have we learned from exploring Earth’s harshest locations? That pretty everywhere we look for life, we find it. From smoking hot hydro-thermal vents to icy deserts, up in clouds and inside rocks, extremophiles have found a way to survive. These survivors and adapters are not only teaching us about life on Earth, but expanding the possibilities of where life can exist elsewhere. Earth mysteries are a wide range of spiritual, quasi-religious and pseudoscientific ideas focusing on cultural and religious beliefs about the Earth, generally with regard to particular geographical locations of historical significance. Believers in Earth mysteries generally consider certain locations to be "sacred", or that certain spiritual "energies" may be active at those locations. The term "alternative archaeology" has also been used to describe the study of Earth mystery beliefs. The study of ley lines originates in the 1920s with Alfred Watkins. The term "Earth mysteries" for this field of interest was coined about 1970 in The Ley Hunter journal, and the associated concepts have been embraced and reinvented by movements such as the New Age Movement and modern paganism during the 1970s to 1980s. Some New Age believers engage in travel to locations they consider important according to their beliefs; for example, Stonehenge is a popular destination among New Age seekers. For those of us who are over run by our curiosities this just might be the video in which you are introduced to life forms of all different species that by human standards are over all hazardous and dangerous, to say the least. Somehow, nature has made these specs of life in such manner to withstand abnormal surroundings. Take a look as this video is sure to broaden your horizons!

S5 Ep15: Defusing the Population Bomb5m51s

S5 Ep15: Defusing the Population Bomb

Is overpopulation real? Is Earth filling up with too many humans? How many people can Earth hold, anyway? As our species approaches 8 billion, human overpopulation is a major concern for many people. How can we reduce poverty and our impact on the environment? Do we need a forced one-child policy or something? Maybe not, because when we look at the science and history, populations seem to control

S5 Ep16: Why Are There As Many Males As Females?5m20s

S5 Ep16: Why Are There As Many Males As Females?

In almost every animal species on Earth, equal numbers of males and females are conceived. Why is that? Especially in populations like lions or elephant seals, where most males don’t get to mate? That’s survival of the laziest, not survival of the fittest. It turns out that in most cases, an equal balance of the sexes is the evolutionary stable strategy. From Charles Darwin to Ronald Fisher to W.D

Congressional Delegation: Crash Course Government #13

What are all these federal agencies about? Well, the president has a lot of stuff to do as the chief executive, and as much as Americans like to talk about personal responsibility, the president can't really do all this stuff alone. Because it's a huge job! Same deal with Congress. So, they delegate authority. This is where all the government agencies and stuff come from.

Bureaucracy Basics: Crash Course Government #15

Bureaucracies tend to be associated with unintelligible rules and time-wasting procedures, but they play an important, though controversial, role in governing.

This week Craig looks at the expressed powers of the President of the United States - that is the ones you can find in the Constitution.
