The Mechanics of "Brain Freeze" headaches

Scientists have studied blood flow changes to come up with a theory

Headaches of all sorts are one of those blind spots in modern medicine. We know surprisingly little about where they come from, and how to make them leave. From cluster headaches to migraines to "brain freeze," these excruciating phenomena have been very mysterious… until now.
 
The phenomena of "brain freeze" (also known as an "ice cream headache") may seem a bit trivial to draw the attention of a multi-national, multi-disciplinary team of medical researchers. But the researchers decided to study brain freeze as a model for understanding all other sorts of headaches. A gateway headache, if you will.

National Take-Back Day for prescription drugs

It is important to safely dispose of old prescription drugs.

 

The Drug Enforcement Administration (DEA) arm of the United States government along with its community partners is holding another national day for the public to safely dispose of old drugs. This year's event will be held on April 28, 2012.

One of the main purposes of the program is to give the public another way to prevent pill theft and abuse by elimination potentially dangerous unused, unwanted or expired prescription drugs from homes. In addition, unused drugs that are discarded can inadvertently end up in the nation's water supply, which is another reason for this DEA event.

Polyphasic Sleep: It Just Doesn't Work

Unless your goal is to be more miserable, of course!
Polyphasic sleep is one of those things that only enjoyed a limited popularity until someone invented the internet, and it became something of a fad. (What is it about the internet that fosters these oddball fixations?) Many people have attempted polyphasic sleep. But any who claim to have mastered it are, according to one biologist, either liars or suffering from a sleep disorder.
 
Most of us, most of the time, experience monophasic sleep. You go to bed, sleep in one reasonably contiguous chunk, then get up and go about your day. Duophasic sleep is also common, including the tradition in Latin countries of the afternoon siesta.
