Texting While Driving Rises in U.S.
There was a 50 percent increase in texting while driving in the United States in 2010 and about one in five drivers say they've sent text messages or emails while on the road, according to a National Highway Traffic Safety Administration study released Thursday.

The increase in this dangerous practice occurred despite a growing number of states that have banned texting while driving. Last month, Pennsylvania became the 35th state to outlaw the behavior, the Associated Press reported.
The NHTSA study found that the number of drivers who texted or used other hand-held devices while behind the wheel increased from 0.6 percent in 2009 to just under one percent last year.
The use of headsets also increased from 0.6 percent to 0.9 percent, but the use of handheld cell phones remained steady at five percent.
An NHTSA survey of more than 6,000 drivers 18 and older found that 18 percent of them said they've sent text messages or emails while driving.
"It is clear that educational messages alone aren't going to change their behavior," Jonathon Adkins, a spokesman for the Governors Highway Safety Association, told the AP. "Rather, good laws with strong enforcement are what is needed. Many drivers won't stop texting until they fear getting a ticket. The increase shows what an uphill challenge distracted driving remains."
Yawns Most Contagious Among Family, Friends: Study
Yawning family members or friends are more likely to make you yawn than strangers, according to a new study.
Italian researchers observed 109 people for up to two hours in their natural setting and recorded when the subjects' yawns triggered yawns in other people, ABC News reported.
The study found that yawns were most contagious among family members and life partners, followed by friends, and then acquaintances and strangers.
"Yawn contagion is affected by the empathic bond that links two people," the University of Pisa researchers said in a news release, ABC News reported.
The study was published in the journal PLoS One.
CooperVision Contact Lenses Recalled
Silicone oil residue on certain lots of CooperVision Avaira Aquaform Sphere soft contact lenses has prompted a recall of the products, the U.S. Food and Drug Administration said Wednesday.
The oil residue can cause hazy or blurry vision, discomfort or eye injuries that require medical treatment.
The recalled lenses were made between Feb. 1, 2011 through Aug. 24, 2011 and distributed from March 2, 2011 through Nov. 15, 2011.
Consumers with these contact lenses should stop wearing them and contact an eye professional for advice, the FDA said.
