If superheroes are one of the ultimate expressions of individualism, what are we to make of Ant-Man, a Marvel Comics character based on one of the least individual, most collective creatures on the planet?
Ant-Man can shrink to the size of an ant — and, in the movie which opens this weekend, ants are his greatest allies. "The ants are loyal, brave and will be your partners on this job," explains the scientist who invented Ant-Man's supersuit.
Lightning strikes have killed at least 20 people in the U.S. so far this year, according to the National Weather Service. That's higher than the average for recent years, the service says.
Most people who are injured or killed by lightning, it turns out, are not struck directly — instead, the bolt lands nearby.
That's what happened to Steve Marshburn in 1969. He was working inside a bank and says lightning somehow made its way through an ungrounded speaker at the drive-through window to the stool where he was sitting.
Air pollution isn't just bad for your health.It can have dramatic effects on weather and climate. In fact, a team of scientists believes that air pollution from industries and traffic could have caused the extreme floods that devastated southwest China in 2013.
It's almost impossible to ignore a screaming baby. (Click here if you doubt that.) And now scientists think they know why.
"Screams occupy their own little patch of the soundscape that doesn't seem to be used for other things," says David Poeppel, a professor of psychology and neuroscience at New York University and director of the Department of Neuroscience at the Max Planck Institute in Frankfurt.
Playing sports has always been important to 31-year-old Erik Johanson, a city planner in Philadelphia. Johanson thrived in baseball and ice hockey as a kid, he says — "one of the best players on the team in high school."
Today, Johanson is married and expecting his first child but is still passionate about ice hockey — and about winning. He plays on a highly competitive team of guys who got together after college and still play weekly in an adult league; they hope to take the crown this year.
