Genetic variations may determine lung function and susceptibility to maternal smoking

A tiny variation within a single gene can determine not only how quickly and well lungs grow and function in children and adolescents, but how susceptible those children will be to exposure to second-hand tobacco smoke, even in utero, according to researchers from the University of Southern California.

Nanotubes sniff out cancer agents in living cells

A multidisciplinary team at the Massachusetts Institute of Technology (MIT) has developed carbon nanotubes that can be used as sensors for cancer drugs and other DNA-damaging agents inside living cells. The sensors, made of carbon nanotubes wrapped in DNA, can detect chemotherapy drugs such as cisplatin as well as environmental toxins and free radicals that damage DNA.
