The number of serial murders is dwindling, along with the public’s fascination with them. The golden age of serial killers is probably past.
Statistics on serial murder are hard to come by—the FBI doesn’t keep numbers, according to a spokeswoman—but the data we do have suggests serial murders peaked in the 1980s and have been declining ever since. James Alan Fox, a criminology professor at Northeastern University and co-author of Extreme Killing: Understanding Serial and Mass Murder, keeps a database of confirmed serial murderers starting in 1900. According to his count, based on newspaper clippings, books, and Web sources, there were only a dozen or so serial killers before 1960 in the United States. Then serial killings took off: There were 19 in the 1960s, 119 in the ’70s, and 200 in the ’80s. In the ’90s, the number of cases dropped to 141. And the 2000s saw only 61 serial murderers.
A Physicist Explains Why Parallel Universes May Exist
Recent discoveries in physics and astronomy, [Brian Greene] says, point to the idea that our universe may be one of many universes populating a grander multiverse.
“You almost can’t avoid having some version of the multiverse in your studies if you push deeply enough in the mathematical descriptions of the physical universe,” he says. “There are many of us thinking of one version of parallel universe theory or another. If it’s all a lot of nonsense, then it’s a lot of wasted effort going into this far-out idea. But if this idea is correct, it is a fantastic upheaval in our understanding.”
Nobel Prize winning biologist says DNA can electromagnetically teleport a duplicate of itself between test tubes.
A Nobel prize winning scientist who shared the 2008 prize for medicine for his role in establishing the link between HIV and AIDS has stirred up a good deal of both interest and skepticism with his latest experimental results, which more or less show that DNA can teleport itself to distant cells via electromagnetic signals.
