Tears Chemical Turn-off Weizmann Institute of Science

Tears Chemical Turn-off Weizmann Institute of Science - According to Noam Sobel, a cognitive neuroscientist at the Weizmann Institute of Science in Rehovot, Israel, tears contain chemical signals that decrease sexual arousal and testosterone levels in men, reports Nature.

In the study, men were asked to sniff vials containing either the women's tears or saline that had been applied to their cheeks.

Results showed that men who sniffed the tears perceived those women as sexually less attractive than did men who sniffed saline.

And men who took a whiff of tears (and not saline) reported a decrease in sexual arousal. These men also reported reduced activity in the areas of brain that are associated with sexual arousal, such as the hypothalamus.

"I think the study has used sound methodology and the results indeed are fascinating. But as far as I know, there is no clear logical, theoretical or empirical justification to design a study on the effects of tears on sex," Nature quoted Ad Vingerhoets, who studies emotion at Tilburg University in the Netherlands, as saying.

Interestingly, on the other hand, tears are considered to heighten empathy and induce caring behaviour, and they act as sexual attractants in mice but decrease sexual arousal in humans.

Urban Meyer Stepping Down

Urban Meyer Stepping Down - Well, it appears as if it’s deja vu all over again.

Less than 12 months after retiring and then un-retiring, Urban Meyer is apparently stepping down as Florida’s head coach. There’s no word on if he will be stepping back up tomorrow.

According to Todd Wright of Sporting News radio, GatorUpdates.com and AOL Fanhouse‘s Brett McMurphy Meyer will announce at a 5 p.m. ET press conference Wednesday that he is resigning/retiring as the Gators’ head coach. There are no further details available at this time, other than GatorUpdates reporting over the weekend that Meyer checked into a hospital the week of the UGA game and has been undergoing tests since.

Obviously, we’ll have more on this story throughout the day and well into the night…

Matt Cassel Undergoes Appendectomy

Matt Cassel Undergoes Appendectomy - The mystery of Matt Cassel missing practice Wednesday coupled with the Kansas City Chiefs promoting quarterback Tyler Palko has been solved.

The team has announced that Cassel underwent an appendectomy on Wednesday morning. The Chiefs say they expect Cassel to return to work this week. Returning to work and being ready to perform well in the team’s biggest game of the season on Sunday against San Diego are two different things. ESPN’s Adam Schefter is reporting the Chiefs are viewing Cassel as being questionable to play in the game.

Clearly, this is terrible timing. The Chiefs are 8-4 and would take a major step toward the playoffs with a win over the Chargers. Cassel has played very well for the past two months. If he can’t play, the brittle Brodie Croyle would face the Chiefs in his first action of the season. Croyle last played in Week 13 of the 2009 season.
