Next Up: Fourth-Hand Smoke?

1 Dangers of Third-Hand Cigarette Smoke

"Everything is toxic in certain amounts. If 3rd hand smoke were so cancer-causing, everyone would be dead from 2nd hand smoke."
- Ernest in the comments

If your residence was previously inhabited by a smoker, you should consider throwing out the furniture, ripping up the carpet, and tearing out the drywall, according to researchers from Lawrence Berkeley National Laboratory in California. Better yet, you might want to demolish the entire building and cart the rubble off to a toxic waste dump. The researchers found that the residue of cigarette smoke that adheres to objects in the room can leach back out into the atmosphere in the form of toxic and cancer-causing substances. Among the toxic substances are heavy metals and even radioactive elements. The new study appears in the current issue of the Proceedings of the National Academy of Sciences.

Have a Drink for Your Bones

2 Beer Could Help Prevent Osteoporosis

"My twin sister likes a glass of wine, while I drink only light beer. My sister has fallen and broken some bones, whereas I have never broken anything."
- Irene Huls in the comments

Beer is a great source of dietary silicon, which is key for bone density, leading researchers in the Department of Food Science & Technology at the University of California, Davis, to say that drinking beer could help prevent osteoporosis. The silicon in beer comes in the form of orthosilicic acid. Researchers said beers that are lighter in color tend to have more of the acid, perhaps because the barley used is subjected to less heat to make a lighter beer. There were very high levels of the acid in the hops used to make the beer, but hops are used in much smaller quantities than grains are in beermaking, so it's really the content of the grain that seems to make a difference.

Hormonal Alterations to Blame

3 Anorexics Have Excessively Fatty Bone Marrow

Contrary to what one might think about the body fat content of people with anorexia nervosa, a new study reveals that they have extremely high levels of fat in their bone marrow. The findings, from research at the Children’s Hospital Boston and published in the February issue of the Journal of Bone and Mineral Research, are based on MRI imaging of the knees of 40 young women. Twenty of the subjects had the disease; 20 did not. Participants with the disease showed an excessively high content of fat in their bone marrow indicating that, because of hormonal changes due to malnutrition, the bone marrow of anorexics stop making healthy bones and form fat instead. Scientists are not sure why this happens but one theory is that it’s the body’s way of preserving heat and storing energy.

Double Duty Drug

4 Statins Fight Cataracts

Statins, drugs used to lower cholesterol, have been found to reduce the risk of cataracts in men aged 45 to 54 by 40 percent, according to a new study published in the February issue of the Annals of Epidemiology. Says Dr. Gabriel Chodick (pictured), Department of Epidemiology and Preventive Medicine at Sackler Faculty of Medicine at Tel Aviv University and lead researcher of the study, "It seems that [statins] protect the eye from inflammation and ocular nerve cells from a process of oxidization. But ours is the first study to show such a strong association in such a large population." Chodick believes that, perhaps someday, even people who do not have elevated cholesterol may be taking statins daily - but more research is needed before this becomes medically acceptable.
