We’ve all been there before: On a hot day, you reach for an ice cold drink or a big scoop of ice cream - and are shortly met with excruciating pain.
We’re talking the dreaded “brain freeze,” - often dubbed an “ice cream headache” - and a new study claims to have finally unlocked clues as to what causes this chilly sensation. The researchers behind the study say their findings may lead to better treatments for other headache sufferers, such as people with migraines or those with traumatic brain injuries.
Almost everyone has felt brain freeze at some point in their lives, according to the study and the effect is triggered by an ice-cold sip of liquid or a slurp of an ice cream or some other chilly product hitting the mouth’s upper palate. But scientists have long been unable to explain the phenomenon - until now.
For the study, presented this week at the Experimental Biology 2012 meeting in San Diego, researchers induced brain freeze in 13 healthy adults by having them sip ice cold water with a straw on their upper palate. The researchers monitored participants’ blood flow in their brains with a “transcranial Doppler test,” and found the sudden headache seems to be triggered by an abrupt increase in blood flow on the brain’s anterior cerebral artery. The pain disappears when that artery constricts, an effect researchers reproduced by having participants drink warm water.
I’ll have a science-flavored Slurpee, please.
Cool. And yes, that was totally pun intended…

Feelings between Selena Quintanilla and Chris Perez took root on a return flight from Acapulco, Mexico to their home state of Texas. There was turbulence during the ride and, seeing how scared Chris was, Selena held his hand and assured him everything would be alright. At the time, Chris had already been a guitarist for the band Selena y Los Dinos for a year, with Selena as the band’s frontwoman.
The New Orleans Saints’ defense maintained a lucrative bounty system during the last three seasons that rewarded players for injuring opponents and causing fumbles and interceptions, the National Football League announced Friday.
The bounty was financed by as many as 27 players and administered by the former defensive coordinator Gregg Williams, who is now the defensive coordinator for the St. Louis Rams. The N.F.L. said that neither Coach Sean Payton nor General Manager Mickey Loomis did anything to stop the bounties when they were made aware of them and the league’s investigation.
Bounties are a violation of N.F.L. rules and could lead to severe sanctions, including suspensions and the forfeiture of draft picks. Commissioner Roger Goodell will decide the discipline. In 2007, as a result of the improper videotaping of opponents’ signals in a case that became known as Spygate, the N.F.L. took away a first-round pick from the New England Patriots and fined Coach Bill Belichick $500,000 and the team an additional $250,000.
“The payments here are particularly troubling because they involved not just payments for ‘performance,’ but also for injuring opposing players,” Goodell said in a statement. “The bounty rule promotes two key elements of N.F.L. football: player safety and competitive integrity. It is our responsibility to protect player safety and the integrity of our game, and this type of conduct will not be tolerated. We have made significant progress in changing the culture with respect to player safety and we are not going to relent. We have more work to do and we will do it.”
The investigation began in 2010 when an unnamed player accused the Saints of targeting opponents, including Brett Favre and Kurt Warner, who were both injured against New Orleans during its Super Bowl run. That player retracted the allegation, but the investigation was revived in the latter part of the 2011 season when the N.F.L. received what it called significant and credible new information.
The N.F.L. said the total amount of money in the pool might have reached $50,000 or more at its height during the playoffs of the 2009 season, when the Saints won the Super Bowl. The system paid players $1,500 for a “knockout” and $1,000 for a “cart-off,” with payouts doubling or tripling during the playoffs. The N.F.L. said it interviewed a wide range of individuals and reviewed about 18,000 documents totaling more than 50,000 pages, including the use of outside forensic experts to verify the authenticity of key documents.
Who dat bunch of assholes? Disgusting.

Childhood poverty among Latinos leads nation (Pew Hispanic Center)
A report released yesterday shows that in 2010 there were almost 6.1m Latino children living in poverty, more than any other ethnic group. The Pew Hispanic Center notes that this is partly a result of the poverty which has spread from the “Great Recession” of 2007-09 and has destroyed a significant amount of the nation’s wealth. A previous Pew report showed that this wealth destruction hit the Hispanic community particularly hard. Between 2007 and 2010, the number of Latino children living in poverty increased by 36.3%, compared to a 17.6% increase in the number of white children in poverty, and an 11.7% increase for black children during the period.
Also, according to the Pew Hispanic report:
This negative milestone for Hispanics is a product of their growing numbers, high birth rates and declining economic fortunes. According to the 2010 U.S. Census, Hispanics today make up a record 16.3% of the total U.S. population. But they comprise an even larger share—23.1%—of the nation’s children, a disparity driven mainly by high birth rates among Hispanic immigrants.
Of the 6.1 million Latino children living in poverty, more than two-thirds (4.1 million) are the children of immigrant parents. The other 2 million are the children of parents born in the U.S. Among the 4.1 million impoverished Latino children of immigrants, the vast majority (86.2%) were born in the U.S.
The U.S. Department of Health and Human Services has announced sweeping new guidelines for women’s health care which will change everything from distribution of birth control pills to administration of breast exams — and will mean insured women will no longer pay anything out of their own pocket.
