May 4 SciCafe: The Race for Rare Earths and Other Metals

News posts

Cell phones, hybrid cars, missile defense systems — and many other modern technologies — depend on components that include elements known collectively as rare earth metals. At the next SciCafe on Wednesday, May 4, Curator James Webster of the Museum’s Department of Earth and Planetary Sciences will be discussing these elements’ properties as well as the pressing issues of supply and sustainability. Dr. Webster recently answered a few questions about the topic.

What are rare earth metals?

It depends on who you ask. To many, the rare earth metals are 17 of the heavier known elements that exhibit similar but unique chemical, magnetic, optical, and electrical properties. They are silver to gray in color, relatively soft, chemically reactive, exhibit high melting temperatures, and are crucial to many modern technologies. But these metals have been mischaracterized and are incorrectly named. Most of the rare earth metals are simply not that rare: they are actually more abundant in the crust of our planet than metals like silver and lead.

Jane McGonigal: How Games Can Change the World

News posts

On Wednesday, February 2, Jane McGonigal,author of Reality is Broken: Why Games Make Us Better and How They Can Change the World, will discuss why games are engineered to maximize human potential and how they can change and influence life in the real world. She recently answered a few questions about her research.

How popular is gaming? What’s behind this popularity?

Currently there are more than half a billion people worldwide playing online games at least an hour a day — and 183 million in the U.S. alone. The younger you are, the more likely you are to be a gamer: 97% of boys under 18 and 94% of girls under 18 report playing videogames regularly. And the average young person racks up 10,000 hours of gaming by the age of 21. That’s 24 hours less than they spend in a classroom for all of middle and high school if they have perfect attendance. It’s really a remarkable amount of time we’re spending playing games. Five million gamer in the U.S., in fact, are spending more than 40 hours a week playing games — the equivalent of a full time job!

Why is this happening? According to my research, it’s because games do a better job of provoking our most powerful positive emotions, like curiosity, optimism, pride, and a desire to join forces with others to achieve something extraordinary. Games are also a particularly effective way to bond with our friends and family, strengthening our real-life and online social networks in ways that no other kind of social interaction can.
