The video documents a seagull “dancing” to bring earthworms to the surface.  When humans do this, it’s called “worm-charming” or “worm-grunting.”  Wood turtles also use this technique, by repeatedly bumping their carapace against the ground.

Some people ask me “Why bother to collect old newspapers? If I want to read dry, boring history, I can just get a history book.” My answer to this is that even the best of history books leave out some mighty interesting aspects of historical events. The only way they can be re-discovered, is through reading original newspapers published during the time of the event. The assassination of president James Garfield in 1881 is a prime example of this.

Discover Magazine references several studies on the importance of zoning out, including a University of Santa Barbara case that asked participating students to read from—what else—War and Peace and to tap on a computer key when they weren’t thinking about the book. On average, the students reported wandering off topic 5.4 times in 45 minutes. Depending on the experiment, we may spend even more time—up to 50 percent to be exact—not thinking about the task-at-hand.

All of which, the article says, is a good thing.

Two big communications satellites collided in the first-ever crash of two intact spacecraft in orbit, shooting out a pair of massive debris clouds and posing a slight risk to the international space station.

NASA said it will take weeks to determine the full magnitude of the crash, which occurred nearly 500 miles over Siberia on Tuesday.

“We knew this was going to happen eventually,” said Mark Matney, an orbital debris scientist at Johnson Space Center in Houston.

NASA believes any risk to the space station and its three astronauts is low. It orbits about 270 miles below the collision course. There also should be no danger to the space shuttle set to launch with seven astronauts on Feb. 22, officials said, but that will be re-evaluated in the coming days.

The collision involved an Iridium commercial satellite, which was launched in 1997, and a Russian satellite launched in 1993 and believed to be nonfunctioning. The Russian satellite was out of control, Matney said.

The Iridium craft weighed 1,235 pounds, and the Russian craft nearly a ton.

In humans, there are four tiny areas of the brain that some researchers say form a circuit of love. [Dr. Bianca] Acevedo, who works at the Albert Einstein College of Medicine in New York, is part of a team that has isolated those regions with the unromantic names of ventral tegmental area (VTA), the nucleus accumbens, the ventral pallidum and raphe nucleus.

The hot spot is the teardrop-shaped VTA. When people newly in love were put in a functional magnetic resonance imaging machine and shown pictures of their beloved, the VTA lit up. Same for people still madly in love after 20 years.

The VTA is part of a key reward system in the brain.

“These are cells that make dopamine and send it to different brain regions,” said Helen Fisher, a researcher and professor at Rutgers University. “This part of the system becomes activated because you’re trying to win life’s greatest prize – a mating partner.”
