Question Your World: How Did We Become Who We Are?

As we move into the future with more powerful technology and a better understanding of the past we are starting to piece together the past as accurately as possible. Our origins have fascinated us for nearly all of recorded history and continue to do so today. With this better understanding we can finally start to answer some of the big questions about our existence on Earth as the dominant species. So, how did we become who we are?

Question Your World: Can We Increase Our Longevity?

Humanity has been fascinated by the concept of longevity. In the past 200,000 years of residence on this planet we've implemented a lot of technological changes that impact nearly every aspect of our lives. Our ability to eat food comfortably, stay warm in cold weather, and even transplant vital organs help improve our standards of living for comfort and health.

Question Your World: How Accurate Are Our Measurements of the Universe?

Knowing something is a pretty relative concept. For a long time we knew that the Earth was the center of the universe, later we learned we were wrong about what we once knew. So, accuracy means a lot when we say we know things. Using technology, we've been able to accurately know a lot of things about our natural world. There are still many things big things left to learn about, such as the size of the known universe. How accurate are our measurements of the universe?

Question Your World: Is There A Glue That Can Help Fix Our Wounds?

Busted door knobs, broken heels, and cracked glasses are a few things that can be fixed using super glue. The quick bonding adhesive works on nearly everything, perhaps that's why this glue is considered to be super. As amazing as this glue is it still can't be used to help us seal up surgical cuts and incisions due to its toxicity. So, is there a way to make glue that won’t be dangerous for us?

Question Your World: Can We Control Aging?

Every event in the universe that we have been able to observe is deeply entangled with time. Time's forward impact has an influence on everything from the forming of distant galaxies to the wear and tear within our cells. The impact time has on us is called aging. This is a constant and forward moving process, but does it have to be? Can we control aging? Learn more in this Question Your World radio report produced by the Science Museum of Virginia.

Question Your World: What's Up With Moons?

From our closest celestial neighbor to distant objects that orbit planets, moons are pretty interesting. The more we learn about them the more interesting they become. Scientists are constantly looking at various moons as future projects, but why? What's up with moons? Find out in this Question Your World radio report produced by the Science Museum of Virginia.

Question Your World: How Does the Brain Make Decisions?

Decisions, decisions, decisions! Our lives are basically a series of decisions, on after the other. The big and small decisions we make shape and guide everything in our lives. So, the big question right now is, how does the brain make decisions? Learn more in this Question Your World radio report produced by the Science Museum of Virginia.

Question Your World: How Did Technology Play a Role in the Comet ISON Story?

For a long time humanity has relied on technology to help us understand more about the natural world. For example, we can look up at the moon all we want, but without technology we would never see the detailed ridges on its surface or know what its dust is like. Observations and collecting data are just two of the many ways that technology can play a role in celestial happenings.
