KVUE TV News, Channel 24, Jan. 22, 2007 AUSTIN -- Last week's ice storm put quite a damper on things for many of us, but it may have also stifled cedar pollen. Doctors say the worst of the season may be over, but some scientists say we could be in for more severe seasons down the road. With all the rain and last week's freeze, a lot of the cedar has died off. While that may make for a milder tail-end of this season, researchers at University of Texas Medical Branch say things could get worse in years to come. Researchers at UTMB recently discovered a stronger protein in cedar pollen. They say pollen with more protein could mean more severe symptoms. Researchers at UTMB believe the stronger protein in cedar pollen may be linked to environmental pollution.
