The Science Behind The Ice Cream Brain Freeze!

Delicious, beautiful, and bound to cause a headache.

The ice cream headache is one of the most common and most hated sources of headache.  When you’re tucking into a delicious ice cream treat or slurping down a milkshake, the last thing you want is that stabbing pain in your skull from getting a little too enthusiastic with your eating.  You get it, I get it, even Harvard students get it, which is why Harvard Medical School students have been inducing ice cream headaches in the lab in order to study them.  As it turns out, ice cream headaches are a close cousin to migraines and people who have migraines are more likely to get brain freeze.

“The brain is one of the relatively important organs in the body, and it needs to be working all the time,” said study researcher Jorge Serrador.  ”It’s fairly sensitive to temperature, so vasodilation [the widening of the blood vessels] might be moving warm blood inside tissue to make sure the brain stays warm.”

Harvard brought 13 research subjects into their labs and hooked them up to various brain monitoring devices.  They gave the subjects ice-cold water to drink and told them to raise their hands when they felt the headache coming on and when it was going away.  While studying the brain freeze victims, they noticed that the anterior cerebral artery expanded, letting in more blood and causing the pressure.  When the artery constricted and reduced blood flow, the pain subsided.  So, basically, an ice cream headache is the brain trying to deal with excess cold, much like 3D headaches are the brain trying to deal with excess input.

Canadian High Schoolers Send Lego Astronaut Into Space!

Canada’s first astronaut?

For four and a half months, Canadian high school students Matthew Ho and Asad Muhammed spent every Saturday working on a project.  No, it wasn’t restoring an old car, it was building a homemade satellite/space vehicle.  Somehow, they not only managed to build their spacecraft, they managed to send a Lego minifigure into space.  It’s a shame it wasn’t one of the official Lego astronauts, but the important thing is Canada has gotten someone into orbit!  It’s a victory for the Canadian space program!

The pair were inspired by other videos of people sending balloons into space, possibly these guys.  The two spent only $400 to build their spacecraft, though the planning was meticulous.  They wanted their Lego man to launch and return to them in Canada to avoid having to cross the border to retrieve him.  The ascent took an hour and five minutes; after the balloon popped, the descent took only 30 minutes.  The homemade spacecraft consisted of a lightweight Styrofoam box carrying three point-and-shoot cameras, a wide-angle video camera, and a cellphone with GPS to track the landing. The balloon was bought online and filled with helium from a party store; two mitten warmers were used to ensure the electronics didn’t get too cold on the trip into space.
