In celebration of National Shark Week, UCTV visits the Birch Aquarium to hear from an expert on leopard sharks, Andy Nosal, a Ph.D. student of Scripps Institution of Oceanography.
Leopard sharks are a special species of shark found only along the West coast of North America, their territory spanning from Washington to Baja California. A distinctive characteristic of these creatures is their mild temperament. Unlike most sharks, which will bite anything that might be food, leopard sharks are timid and have such small mouths that they pose essentially no danger to humans. In fact, a leopard shark bite on a human has never been recorded by the International Shark Attack File.
Every Summer La Jolla Shores is the gathering site of hundreds of leopard sharks. A common misconception of this behavior is that these sharks convene here to mate or give birth, but in fact scientists are not quite certain what they do at this annual conference.
Watch “Local Legends: The Leopard Sharks of La Jolla Shores” to see what Nosal has determined about why these sharks flock to La Jolla Shores and what they do there.

We may not often think of the role imagination plays in our society and in our everyday lives. Without imagination, would the internet exist? Would Edison have invented the light bulb? Would primitive man have invented the wheel?
Literature is a field where the imagination is encouraged to run freely. Science fiction in particular pushes the imagination to its limits. UC San Diego recently created a center devoted to this creative aspect of our minds, dedicated to the very imaginative author of 2001: A Space Odyssey, Arthur C. Clarke.
Watch “The Literary Imagination with Jonathan Lethem and Kim Stanley Robinson” to hear these two science fiction authors discuss the literary imagination in honor of the grand opening of UC San Diego’s Arthur C. Clarke Center for Human Imagination.

Entrepreneurship plays a vital role in the U.S. economy as it embodies the spirit of American capitalism.
However, as the necessity of capitalism dictates, some of these entrepreneurs must fail in order for others to succeed.
According to the Bureau of Labor Statistics, survival rates of new start-ups have been dwindling since the recession began. The BLS reports, “The period from 1993 to 2006 was marked by an increase in the number of births and deaths [of start up companies], indicating a higher amount of business ‘churn’ — that is, new business establishments entered and old establishments exited the economy in greater numbers. Since the most recent recession began in December 2007, births have experienced the steepest decline in the history of the series.”
But even in this tough economy, UC San Diego Alumni have managed to create and sustain successful businesses. Watch “Start Me Up! Entrepreneurs at Career Boost Camp 2013” to hear from a chief creative officer, a computer and electrical engineer, and other entrepreneurs as they share their tales of successful start ups.

There are many theories as to how humans evolved to who we are today.
Fossils tell us that there once existed many human-like species, such as the Neanderthals, that had similar yet archaic skull shapes. Some people believe that there was just one ancestor of our modern species who evolved into the species we are today — but that straightforward trajectory seems too simple to be evolutionarily possible. Another theory suggests that there were many variations of our ancestors, but whose lineages did not persist as ours did. Eventually, modern humans replaced those sub-human species — but not before our ancestors interbred with them to create the variations of humans we have today.
In this episode of the latest CARTA series, Behaviorally Modern Humans: The Origins of Us, Chris Stringer of the Natural History Museum of London takes us through his analysis of the fossil record to present his theory on how humans and our ancestors evolved and dominated the globe. Then, Michael Hammer from the University of Arizona discusses the possibility of interbreeding of human subspecies to create the species known as modern humans. Followed by Richard “Ed” Green of UC Santa Cruz who also talks about the possibility of interbreeding, but with species even outside of Africa.
