Need Another Reason To Quit Smoking – Third Hand Smoke
Need another reason to add “Quit Smoking” to your New Year’s resolutions list? How about the fact that even if you choose to smoke outside of your home or only smoke in your home when your children are not there – thinking that you’re keeping them away from second-hand smoke – you’re still exposing them to toxins? In the January issue of Pediatrics, researchers at MassGeneral Hospital for Children (MGHfC) and colleagues across the country describe how tobacco smoke contamination lingers even after a cigarette is extinguished – a phenomenon they define as “third-hand” smoke. Their study is the first to examine adult attitudes about the health risks to children of third-hand smoke and how those beliefs may relate to rules about smoking in their homes.

A Plastic That Cools
Films of a specially designed polymer, just 0.4 to 2.0 micrometers thick, can get colder or hotter by 12 °C when an electric field is removed or applied across them.
Thin films of a new polymer developed at Penn State change temperature in response to changing electric fields. The Penn State researchers, who reported the new material in Science last week, say that it could lead to new technologies for cooling computer chips and to environmentally friendly refrigerators.

Possibles sources of lead poisoning
In what may be the strongest link yet between lead exposure and crime rates, researchers at the University of Cincinnati on Tuesday released new evidence, spanning more than 20 years, that draws a direct relationship between the amount of lead in a child’s blood and the likelihood he or she will commit crimes as an adult.
