A new analysis of topographic and gravity data from Titan, the largest moon orbiting Saturn,  indicates its icy outer crust is twice as thick as has generally been thought.

Is there a vast ocean of liquid water lies under the crust?. The new study suggests that the internally generated heat that keeps that ocean from freezing solid depends far more on Titan's interactions with Saturn and its other moons than had been suspected.

Rain in Southern Arizona is usually scarce - but on November 29th, 25 miles north of Tucson, the soil was soaked. Spouting from a network of pipes, thousands of gallons of water drizzled down onto the world's only and largest man-made experimental watershed, recently completed at the University of Arizona's Biosphere 2.  You can read articles from original Biosphere 2 scientist Jane Poynter here.

Women suffering from sleep apnea have a higher degree of brain damage than men with the disorder, according to a study conducted by researchers at the UCLA School of Nursing.  

Obstructive sleep apnea is a serious disorder that occurs when a person's breathing is repeatedly interrupted during sleep, sometimes hundreds of times. Each time, the oxygen level in the blood drops, eventually resulting in damage to many cells in the body. If left untreated, it can lead to high blood pressure, stroke, heart failure, diabetes, depression and other serious health problems. 10 years ago, this UCLA research team showed that men with obstructive sleep apnea have damage to their brain cells.  

Drinking three to four cups of delicious coffee each day may help prevent type 2 diabetes, according to research published by the Institute for Scientific Information on Coffee (ISIC). Really, that is an actual organization dedicated to promoting the health benefits of coffee.  Some skepticism might ordinarily be warranted but since this is about coffee, it is okay to just accept the science.

Apple's Siri sounds like she cares about your needs, but she is faking it.  But some research by a team of engineers shown at the IEEE Workshop on Spoken Language Technology describes a new computer program that gauges human feelings through speech with substantially greater accuracy than existing approaches. 

Some day you may have a smart phone that identifies your mood.
