Hurricane Ike was still a Category 4 storm on the morning of Sept. 4 when this photo was taken from the International Space Station’s vantage point of 220 miles above the Earth. The season’s seventh named storm was churning west-northwestward through the mid-Atlantic Ocean sporting winds of 120 nautical miles per hour with gusts to 145.

Heated car seats are nice and toasty for your bottom, but it may prove be too toasty for men’s sperms:
Optimal sperm production requires a temperature 1 to 2 °C below
the core body temperature of 37 °C. This is one reason why the testicles hang outside the main part of the body. To test whether heated car seats might be raising scrotal temperatures above this threshold, Andreas Jung at the University of Giessen in Germany and his colleagues fitted temperature sensors to the scrotums of 30 healthy men, who then sat on a heated car seat for 90 minutes.
In what must have been one of the most difficult and most painstaking research projects of all time, a cosmetic surgeon spent hours studying photos of topless models to determine the perfect pair.
Apparently, his findings indicate that the perfect chest isn’t about size. Instead, it’s all about proportion.
“The ideal is a 45 to 55 percent proportion – that is the nipple sits not at the half-way mark down the breast, but at about 45 percent from the top.”
So who came out on top?
