• Just Explain It: What Is Déjà Vu?



    Have you ever experienced déjà vu? You know, the strong feeling an experience is familiar, while at the same time knowing it hasn’t happened before. Where does it come from

    That’s the subject of today’s Just Explain It.

    The truth is, even though 60 to 80 percent of us say we’ve experienced it, déjà vu stumps science as much as it stumps the rest of us. That’s because it happens so quickly and so randomly, it’s very difficult to study.

    Because it’s so hard to study, scientists haven’t singled out a definitive reason as to why déjà vu – which means "already seen" in French – happens. There are, however, two prevailing theories.

    One theory has to do with the areas of the brain that recognize familiarity and recall memories. Although they occupy different parts of the brain, they’re normally in sync. Some scientists theorize that déjà vu occurs when the part that recognizes familiarity misfires and creates a strong sensation of familiarity. They don’t know why it misfires, but it could be Read More »from Just Explain It: What Is Déjà Vu?
  • The Little Secret Of The Concert Business

    Some of the biggest acts in music are hitting the road this summer: Beyonce, The Rolling Stones, Jay-Z and Justin Timberlake, just to name a few.
     
    But have you tried to get tickets to see your favorite megastar?
     
    You can call or go online the moment tickets go on sale, but they can be sold out in seconds.
     
    Why is it so hard to get tickets to the hottest concerts?
     
    That's the subject of today's Just Explain It.

    You might think these concerts sell out so fast because of the high demand for tickets. But the profitable little secret of the concert business is just how small the supply of tickets actually is. In some cases, as little as seven percent of all tickets for an event go on sale to the general public.

    That was the portion of tickets up for grabs to the general public for a Justin Bieber show earlier this year. An investigation by Nashville’s NewsChannel5 found that out of close to 14,000 tickets at the

  • Just Explain It: Predicting Weather Disasters

    Moore, Oklahoma continues to recover from the two-mile-wide tornado that resulted in tragic deaths and devastated the Oklahoma City suburb last week. The financial cost is still being calculated, but one meteorologist estimates it could be one of the costliest tornadoes in history, with a price tag approaching $3 billion. And he may be right.

    That same meteorologist predicted a major hurricane would hit New York City and the U.S. would enter a major drought. That was one year before Hurricane Sandy battered the Northeast and the 2012 drought that rivaled the Dust Bowl of the 1930’s.

    So, who is this forecaster, and what are his other predictions? That’s the topic of today’s Just Explain It.
     
    The meteorologist is Jeff Masters, who co-founded the Weather Underground website. In 2011, he predicted nine weather disasters in the U.S. that would cause $100 billion in damage each in next 30 years. He ranked them based on their potential

  • Environmentalists Unite in Quest to Fight Global Warming

    The nation’s environmental leaders are mounting a double battle against global warming, and they see President Obama’s remaining time in the White House as critical in winning both of them.

    In interviews with the leaders of seven major environmental organizations, they all indicated a sense of unity and urgency on rolling out regulations to control the greenhouse-gas emissions that scientists agree cause climate change and on blocking the Keystone XL pipeline, which would carry carbon-heavy oil sands 1,700 miles from Canada to the Gulf Coast.

    “I was recently with my colleagues at a quarterly CEO meeting with different groups, and I would say I feel very strongly that we’re unified that these two things go hand in hand in an ask to the White House,” said Frances Beinecke, president of the Natural Resources Defense Council. “They’re both very important to the community as a whole.”

    The environmental chiefs don’t want one or the other. They want both. They’re lobbying Obama, who promised
