Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have been awarded $1.3 million for two sets of studies to better understand the health impacts of thirdhand smoke, the noxious residue that clings to virtually all indoor surfaces long after the secondhand smoke from a cigarette has cleared out. Berkeley Lab geneticist and BBDS Scientist, Jian-Hua Mao, will use a genetically diverse population of mice to investigate how components of thirdhand smoke cause genetic damage. (Related news link)
