1 Shed Skin Helps Reduce Indoor Air Pollution

Humans shed their entire outer layer of skin every 2 to 4 weeks. The dust you see on tables and other surfaces in your home and office are the result of that shedding process. Those flakes contain cholesterol and squalene and research has found that the latter reduces levels of ozone which may irritate the eyes, nose and throat, in airplane cabins. Now, a new study of children’s bedrooms and daycare centers finds that “squalene in settled dust ... contributes, in a small way, to the indoor removal of ozone,” reducing indoor ozone levels by between 2 and 15 percent. "It is only within the last 5 years that we've grown to appreciate the central role that squalene (from human skin oil) plays in oxidation chemistry within indoor environments," say researchers.

CEO Gets Defensive

2 Philip Morris CEO: It's Not Hard to Quit Smoking

Philip Morris International CEO Louis Camillei told a cancer nurse that it's not that hard to quit smoking, reports USA Today. The comment was made to Elisabeth Gunderson, a member of The Nightingales Nurses activist group. She says that a patient told her recently that quitting smoking was more difficult than other addictions he's beaten, including crack, cocaine and meth. Camillei, a longtime smoker, admitted that cigarettes are harmful and addictive, but said he believes that since there are more previous smokers in America than current smokers, it's just not that hard to quit. Camillei's opinion was expressed in response to comments made during Philip Morris International's annual shareholder meeting in New York on Wednesday.

Primes Immune System to Attack

3 Effective SIV Vaccine Paves Way for HIV Vaccine

An experimental vaccine against simian immunodeficiency virus (SIV) that is carried into the body by cytomegalovirus (CMV) which is normally non-pathogenic and present in most people, kept the viral load at undetectable levels in over 50 percent of vaccinated Macaques for over a year. These results are exciting because they may provide clues on how to develop an effective HIV vaccine, which has eluded many scientists since AIDS first emerged in humans in the early 1980s. SIV is the non-human primate form of HIV and researchers hypothesize that CMV keeps the immune system primed to attack HIV so it can halt its replication when it first enters the body and evades the immune system. Before human clinical trials can begin, researchers will weaken CMV to prevent any potential health problems.
