In late July and August, something remarkable happens in the air above Lake Murray in South Carolina. Around sunset, hundreds of thousands of purple martins come streaming toward the center of the lake from every direction, swirling together in a massive flock that darkens the sky. After an hour or so, they settle down on Bomb Island in the center of the lake.

If you went to the movie theater this weekend, you might've caught the latest Scarlett Johansson action movie called "Lucy." It's about a woman who develops superpowers by harnessing the full potential of her brain.
When scientists talk about the destruction of rain forests or the acidification of oceans, we often hear about the tragic loss of plants and animals.
But ecologists at the University of California, Berkeley say there's also a human tragedy that frequently goes unnoticed: As fish and fauna are wiped out, more children around the world are forced to work, and more people are forced into indentured servitude, scientists wrote Thursday in the journal Science.

Here in southeastern Virginia, our biggest city, Norfolk, is saddled with an unwanted claim to fame. As The Washington Post has reported, Norfolk is the place "where normal tides have risen 1.5 feet over the past century and the sea is rising faster than anywhere else on the East Coast."
Hate to burst your bubble, glass lab gear. But plastic bubble wrap also works pretty well at running science experiments.
Scientists at Harvard University have figured out a way to use these petite pouches as an inexpensive alternate to glass test tubes and culture dishes. They even ran glucose tests on artificial urine and anemia tests on blood, all with the samples sitting inside bubble wrap.

When 12-year-old Lauren Arrington heard about her sixth-grade science project, she knew she wanted to study lionfish. Growing up in Jupiter, Fla., she saw them in the ocean while snorkeling and fishing with her dad.
In November of 1969, astronaut Alan Bean became the fourth man to walk on the moon. His mission, Apollo 12, arrived at the moon a few months after Apollo 11 made the first moon landing. That historic event celebrates its 45th anniversary Sunday.
Apollo 12 got off to a dramatic start: A storm rolled in as the rocket was scheduled to launch. Bean, with fellow astronauts Pete Conrad and Dick Gordon, sat inside the spacecraft while the bad weather threatened the operation.

Forty-five years ago today, in arguably the greatest technological feat of the 20th Century, two Americans stepped off the ladder of their small landing craft and walked on the surface of the moon.
The first of them, Neil Armstrong, 38, of Wapakoneta, Ohio, pronounced his accomplishment "one small step for [a] man; one giant leap for mankind." The second, 39-year-old New Jersey native Edwin "Buzz" Aldrin, Jr., described what he saw as "magnificent desolation."
Standard economic theory assumes that humans behave rationally and are able to objectively calculate the value (or cost) of the different choices they are presented with. In fact, we pride ourselves on our rationality. Different from the animals, we humans have the unique capacity for logical thought and rational decision making. Or do we?
Malaysia Airlines has released the manifest of passengers who were on that plane that crashed in Eastern Ukraine. We know that many of them were bound for the world's largest AIDS conference in Australia. At the opening of the conference yesterday there was a moment of silence to remember those who had died. Diane Anderson-Minshall is the editor-in-chief of HIV Plus Magazine and asked her about one of the most prominent AIDS researchers who was killed, Dutch scientist Jope Lange.
